Clinical Psychology


Clinical psychology, a branch of psychology, is that body of knowledge and skills which can be used to help persons with behavior disabilities or mental disorders to achieve better adjustment and self-expression. It encompasses the applied areas of diagnosis, treatment, and prevention, as well as the basic area of research. (In British countries the term “clinical psychology” is more or less interchangeable with “medical psychology.”)

In function, clinical psychology overlaps a number of fields. The profession to which it is most closely related is psychiatry. Psychiatrists, although members of a medical specialty whose training includes medical school, general internship,and three years of psychiatric residency, have more in common with clinical psychologists than with other physicians. Because of their medical training, however, psychiatrists, unlike clinical psychologists, can use drugs. Psychotherapy as a major treatment technique and diagnosis are areas common to both clinical psychology and psychiatry, although the two professions make use of somewhat different approaches.

Psychiatry tends to use interviews and mentalstatus examinations, whereas psychology leans more to objective tests and projective devices. Both groups are increasingly directing attention to the rapidly expanding area of prevention. Clinical psychologists have generally been more active in research than psychiatrists, but a marked effort is being made to increase the number of psychiatrists participating in research activities. Clinical psychology also has much in common with social work, particularly in the area of treatment. Social workers are given excellent training in this function— perhaps better training than either of the other two major mental health professionals, clinical psychologists or psychiatrists. Social work has in recent years recognized the weakness of being a profession that has neither an underlying basic discipline nor a body of research, and it is attempting to remedy these difficulties. Clinical psychology borders on the fields of sociology, particularly in its social-psychological aspects, and the ministry, when the latter assumes the “helping” role. Clinical psychology’s relation to anthropology is remote except for the analogies that may be drawn between patterns of collective behavior and forms of individual pathology.

The content of clinical psychology includes large portions of psychopathology, abnormal psychology, and similar areas. It is particularly dependent on personality theory and psychoanalysis for its theoretical underpinnings.

Origins. Clinical psychology is younger than many other branches of psychology. In an organized form it dates from 1896, when Lightner Witmer first established a psychological clinic at the University of Pennsylvania. (Witmer also coined the terms “clinical psychology,” “psychological clinic,” and “orthogenics.”) From the beginning he called for the qualitative study of the individual patient, for therapeutic as well as diagnostic purposes. He acknowledged the need for the detailed consideration and prolonged observation of cases by establishing a children’s hospital–school. Although in its early period the clinic was concerned almost entirely with the retarded child, in later years its major preoccupations were the problems of the superior child, vocational guidance, and speech disability. What has since become known as the “team” approach—coordinated work by representatives of a number of disciplines dealing with the same case—was, after a fashion, adopted at an early date by the clinic. Physicians, especially neurologists, and social workers collaborated on case studies. Witmer emphasized the need for professional training and developed a pattern of attack that included most of the elements of present-day clinics.

While Witmer’s clinic was expanding its activities, the Binet movement in France was gathering force. Rumblings of it had been heard at the turn of the century, and with the publication of the Binet-Simon test in 1905 the potential of the intelligence test first became evident. The Vineland Training School, an institution for the mentally retarded, was among the first to adapt the test to American conditions. There, in 1906, H. H. Goddard started the first American psychological laboratory.

About 1910, a second university clinic, modeled on Witmer’s was organized by Carl Seashore at the University of Iowa. During the same period, J. E. Wallace Wallin began to apply psychological techniques to school children. He started a psychoeducational clinic at the University of Pittsburgh in 1912. Emphasizing the educational, as opposed to the psychopathological significance of clinics, Wallin recommended that clinics be established in association with departments of education rather than with psychology departments.

In the latter part of the nineteenth century and through the early part of the twentieth, the activities of such men as J. M. Charcot and Pierre Janet —but most particularly Sigmund Freud, abroad, and Adolf Meyer in this country—brought prominence to the functional point of view. Their influence led to the development of perhaps the most important type of clinic in this country.

In 1909, in association with the Cook County Juvenile Court of Chicago, William Healy started a behavior clinic. It is from this event that the child-guidance movement dates its origin. Although impressed by Witmer’s clinic, Healy, who was concerned mainly with social pathology, took a different approach. Despite Witmer’s pioneering, Healy’s approach was to have a greater and more lasting effect on clinical psychology specifically and on the field of mental hygiene in general.

Witmer versus Healy. Why this difference? Study of the programs of the two clinics shows Witmer’s strikingly consistent concern with educational problems, primarily with those of the mentally retarded. His emphasis on the intellectualcognitive aspects of personality naturally led to contact with educators in school settings or in institutions for the mentally retarded. When interested in a medical problem, Witmer focused on its physical or neurological aspects. Healy, on the other hand, emphasized the affective aspects of personality, looked at the psychiatric side of medical problems, and dealt with a variety of social agencies and institutions. Healy, it turns out, was wiser in his choice, for the study of the mentally retarded has remained relatively more narrow and distinctly less rewarding than the study of the personality differences associated with psychopathy, neurosis, or psychosis. Events such as those reflected in the mental health bills passed by Congress in 1963 may belie this statement, but professionals treating or doing research in mental disorder, with few exceptions, hold to it. [SeeMental retardation.]

The lack of organized information flowing from the Pennsylvania clinic also served to circumscribe the response to the Witmer approach. Witmer never published a systematic book on the clinical field; his major contributions were papers in his own journal. Holmes’s book (1912) describing the clinic’s procedure is rather anemic and unimaginative. In contrast, Healy’s The Individual Delinquent (1915) is a rounded and challenging work.

The structure of the Pennsylvania clinic may have created additional obstacles to its influence. Because it was established in a university setting and was directed by a nonphysician, the clinic may have been effectively barred from social prominence. Association with student training may have limited its scope. Had the clinic been established in a medical school already recognized as a therapeutic center, or in a market place of social agencies (as Healy’s clinic was), it might have had more general influence. Or perhaps Witmer was ahead of the times.

More important than the content of the programs, the way information was disseminated, or the characteristics of the clinics (or perhaps inextricably woven into all) were the outlooks of the respective leaders. Whereas Witmer’s approach was essentially segmental and static, relatively uninspiring and plodding, Healy’s was total, seminal, and stimulating. Whereas Healy was markedly influenced by the functional psychology of James and the dynamic views of Freud and Meyer, Witmer identified with the less imaginative WundtianKraepelinian approach. A systematic skimming of Psychological Clinic, the journal Witmer founded, leaves one with the feeling that Witmer was burdened by a conservatism which led him to oppose dynamic psychology because it was “unscientific” and “radical.” This attitude is paradoxical for a pioneer. Witmer’s pioneering, however, was not really in new thinking but rather in new material to which old thinking was applied. Healy’s perspective, in comparison, was to prove more suited to the developing field of clinical psychology.

Early developments. Paralleling the growth of the clinics was the establishment of psychological laboratories in hospitals for the mentally disordered. The McLean Hospital, St. Elizabeth’s Hospital, and the Boston Psychopathic Hospital were outstanding. In some respects the work in the hospital laboratories followed conservative academic–experimental lines. In other ways hospital activities promoted the liberal use of test devices.

Since the earliest days of clinical psychology, the American Psychological Association has made attempts to deal with problems related to the field (Fernberger 1932, pp. 42–53). Since 1895 it has taken an interest in the standardization of mental tests. In 1915 a study of the qualifications of mental examiners was initiated. In 1918 a committee appointed to explore the problem reported in favor of the certification of examiners by the association. A certifying committee was appointed in 1920, but by 1923 only 25 members had applied for certification, and in 1927 certification was discontinued. It was started again, however, in 1947.

During the 1930s various systematic efforts were made to deal with clinical psychological problems. Morrow (1946) has described the attempts of university, state, and national organizations to devise standards of training and experience.

In the early 1940s a considerable amount of clinical work was being done in communities and hospitals, as well as in universities (which had, however, taken a decidedly secondary role), by psychologists whose training was, with few exceptions, unsystematically acquired. Although there was wide concern with problems of training, few organized programs had been set up. Whatever background the clinical psychologist had was largely self-determined. His training was surprisingly uninfluenced by programs emanating from universities or other recognized psychological institutions.

Recent developments. Since the 1940s there has been considerable preoccupation with the problems of clinical psychology. The play of a great variety of forces, both within and without psychology, has made clinical psychology into a field that calls upon its practitioners for competence in three major tasks: (1) diagnosis, or the acquisition of knowledge about the origin and nature of existing psychological conditions through the use of tests, measurements, standard interviews, and similar procedures; (2) research, or the advancement of knowledge by a systematic attack, in the laboratory or in the field setting, on specific problems capable of controlled, experimental resolution; and (3) therapy, or the intricate art and science of improving the condition of clients. Beyond these tasks lies always—implicitly at least, but increasingly at an explicit level—the important problem of prevention.

In the 1960s, doctoral training for these tasks calls for a minimum program of four years, one year of which (preferably the third) consists of an internship. Practica, clerkships, and internships are organized on a foundation of basic courses in theoretical, clinical, and dynamic psychology. The type of training program now generally accepted was initially proposed by the Committee on Training in Clinical Psychology of the American Psychological Association in its 1947 report and was further supported in conferences at Boulder (Conference… 1950), Stanford (Strother 1956), Miami (Conference… 1959), and Chicago (Hoch et al. 1966). The 1947 report recommended that clinical training be centered in existing university departments and that field-training units be integrated with university programs. Although proposals have been made for the establishment of special professional schools in clinical psychology, the solution still generally favored is the expansion of existing university psychology departments to meet the needs of clinical psychology. Such a plan underscores the model of the clinical psychologist as a scientist-professional and supports the motto “A clinical psychologist is a psychologist first and a clinician second.”

As the professional consciousness of psychologists has developed, however, universities and field centers have come to recognize the importance of appropriate personality qualities and high intellectual abilities in clinical work. In the past, some professors had a tendency to direct their weaker students—those who did not have the makings of “scientists”—into clinical courses with the hope that they would then be able to find jobs in clinical settings. A number of poorly trained people, generally called “psychometricians,” who presumably were nothing more than psychological technicians, thus entered the field. The present attention to selection and recruitment problems, however, has led to an increase in competently trained researchers and practitioners. Most have come from institutions in which standards have been maintained and a reasonably comfortable relationship exists between academic and clinical psychology. Some have also come from centers where the standards have not been of the highest level, but where exceptionally good people have managed, in one way or another, to educate themselves.

The American Psychological Association has, in recent years, taken an increasingly greater role in setting up standards for evaluating both training and practice in clinical psychology. The Committee on Graduate and Professional Training (American Psychological Association 1945) was followed by the Committees on Training in Clinical Psychology (American Psychological Association 1947; 1948; 1949) and more recently by the Education and Training Board (Conference… 1959). These committees have provided the criteria for approving universities and for recommending their participation in programs of the Veterans Administration and the Public Health Service (Ross 1964; 1965; Ross & Lockman 1964; Goodstein & Ross 1966).

To consolidate and advance standards, the American Board of Examiners in Professional Psychology was organized and, in April 1947, incorporated. It was modeled on the specialty boards in medicine and had similar standards. The board generally requires five years of acceptable experience, in addition to the doctoral degree, for admission to the examination for a diploma. A “grandfather clause,” which expired December 31, 1949, allowed for certification of qualified persons on the basis of experience rather than actual examination.

With the protection of the public in mind, governmental bodies have made several attempts to set the standards for the certification of psychologists. The two types of legislation that have been under consideration by state agencies are exemplified, in their essentials, by the early laws of Connecticut and Virginia. The Connecticut law provides for the general certification of psychologists with a ph.d. degree plus one year of experience; the Virginia law entails the certification of specified kinds of psychologists with a ph.d. plus five years of experience. The consensus among psychologists is that state certification should follow the Connecticut pattern and that “expert” certification should be left to a professional agency, such as the American Board of Examiners in Professional Psychology.

Present picture. Since 1947, the growth of clinical psychology in the United States has been phenomenal. This is reflected, to a small degree, in the following statistics: (1) membership in the Division of Clinical Psychology of the American Psychological Association has risen from 787 in 1948 to 3,048 in 1966; (2) the number of schools fully approved by the Committee on Training in Clinical Psychology of the American Psychological Association has increased from 20 in 1948 to 67 in 1965; (3) there were an estimated 742 graduate students enrolled in doctoral-training programs in clinical psychology in the academic year 1947/1948 compared to 3,340 in 1962/1963; (4) the number of clinical psychologists certified by the American Board of Examiners in Professional Psychology has increased from 234 in 1948 to 1,793 in 1963 (of the total, 1,116 are “grandfathers”); (5) some form of statutory control has been established by 28 states and four Canadian provinces, and non-statutory control has been set up by 18 states.

But this unusual growth has not come about without much travail. An increasing number of questions have arisen which psychology and clinical psychology will have to answer in the coming years: (1) Can psychologists be trained who have both professional and scientific goals in mind? (2) How much application can there be in a field in which basic knowledge is still so meager? (3) Should clinical psychologists devote more time to research? (4) How can socially unprofitable trends toward private practice be curbed? (5) Should training for research and teaching be separated from training for the applications of psychology? (Shakow 1965).

Outside the United States there are signs of increasing interest in clinical psychology (David 1958). Growth rates for the countries differ, however, and the pace is decidedly less rapid outside the United States.

England and Canada. In Britain, the pattern has, in general, been less structured than in the United States. Formal programs, where they do exist, have been modeled on the Maudsley (University of London) pattern, which consists of one to two years of practical experience and a doctoral dissertation. The development of the National Health Service in 1948 led to an increase of clinical psychologists (Summerfield 1958). Whereas at the end of 1945 there were 77 professional psychologists in the British Psychological Society working in mental health, by 1958 the number had increased to some 400. University training facilities have been extended and the pursuit of higher degrees has been encouraged. In English-speaking Canadian universities, training has consisted of a combination of American and English patterns, generally calling for a diploma or special master’s degree after one to two years of practical training, followed by two years of formal research leading to the PH.D. The report on the Conference on the Training of Professional Psychologists, held in May 1965 at the Couchiching Conference Center at Geneva Park, Ontario (Coons 1965), presents a detailed discussion of developments in Canada.

Western Europe. The situation in the western Continental countries is not as encouraging. A strong medical tradition still holds sway, limiting a good deal of the practice of clinical psychology (and particularly of psychotherapy) to physicians. In the last few years, however, these countries have made increasing inquiries about American training programs, and one can expect some growth of clinical training along American lines.

Eastern Europe. In eastern continental Europe, medical influence is even more pervasive. Particular emphasis is placed upon physiological functioning with a corresponding denigration of the place of psychological testing, objective or subjective, and of the study of individual differences generally. Rapid growth of clinical psychology appears less likely.

Japan. In Japan, noteworthy among Eastern countries, psychology is in an active ferment (McGinnies 1960). The field of clinical psychology is developing rapidly despite a number of handicaps—for instance, the rigidity of the university system and the overrepresentation of physicians in the field. Thus, at the 1958 meeting of the Japanese Psychological Association, of the 619 papers presented, representing 11 areas, clinical psychology ranked fourth in number, being preceded only by perception, education, and learning.

Problems and prospects. On the whole there has been a tremendous growth of clinical psychology in the United States and a moderate growth, along similar lines, in other countries. The hope is that countries will work out patterns suited to their own needs and not be guided too much by the patterns established in the United States—patterns that have brought with them problems of their own. A large number of major problems must be solved by both psychology and clinical psychology if clinical psychology is to make its proper contribution to the needs of society and to develop its potential as a profession. These include training both for old and new areas of endeavor, evaluation of both training institutions and individuals, and improvement of existing programs. Specifically, the following issues have to be faced.

Training for research. The role of the university, the role of the field center, and the relationship between the two types of institutions need elaboration. Concomitantly, the content of research needs redefinition so it will encompass the most rigorous laboratory research, systematic naturalistic observation, and a serious attitude of inquiry leading to deliberate efforts to answer questions that arise during clinical operations.

Application. The function of each of the training agencies and the way to integrate their work in institutional and community settings need clarification.

Areas for research and practice. Much imaginative thinking is demanded. New methods of therapy, new methods of diagnosis, and, particularly, preventive methods of education are becoming increasingly important. Clinical psychology must do everything it can to attract persons with the resourcefulness to meet problems in unconventional areas. It is clear that the personnel shortages in the area of mental health will be enormous. Much thought and experimentation must go into making use of a larger pool of persons, for example, younger persons with the ideals and resourcefulness represented in Peace Corps volunteers, older persons such as mothers whose children no longer need their attention (see the experiment by Margaret Rioch et al. 1963), and teachers whose effective use is crucial in the mental health area. In addition, new methods of therapy and prevention must be constantly invented for, and tested on, groups—especially the underprivileged—that have heretofore received little consideration in mental health projects.

University training programs. The proper university settings for training in clinical psychology should be described and the importance of programs coming from unified departments considered. The nature of the doctoral degree granted to clinical psychologists—whether strictly professional (say, a ps.d.) or a combined research degree (the ph.d.)—calls for special discussion. The place and nature of postdoctoral programs, especially such programs for psychotherapy training, should be given equal thought.

Evaluation and regulation. There should be a re-examination of the composition, responsibilities, and standards of those committees that evaluate the performance of institutions, both universities and field centers, and those that regulate the activities of individuals, such as the American Board of Examiners in Professional Psychology and state licensing and certification boards.

Upgrading research and practice. Periodic regional conferences to consider the details of existing and potential training programs would be an effort in the direction of upgrading research and practice. The kind of professional eclecticism proposed by Kubie (1954) or the intensive, integrated approach discussed in detail at the Gould House Conference on an Ideal Program of Training for Psychotherapists (1963) may be possibilities. In addition, methods for making the private practice of psychology more effective and socially useful should be reviewed.

The major problems of clinical psychology continue to lie within the parent field, psychology. Clinical psychology, after a long period spent as part of an academic discipline, has been through the early stages of becoming a profession as well. It is going through the natural disturbances and difficulties that attend a growth process of this kind. These need not be of serious concern, however, if clinical psychology selects its students carefully, for personality as well as intellect; if it trains thoroughly, in spirit as well as letter; if it trains broadly, recognizing that narrowly educated specialists are not true clinical psychologists; if it remains flexible about its training and encourages experimentation; if it does not sacrifice more remote goals to the fulfillment of immediate needs; if it maintains its contact with its scientific background, remaining alert to the importance of theory as well as practice; if it keeps modest in the face of the complexity of its problems, rather than becoming pretentious—in short, if it finds good people and gives them good training its future in society and as a profession is then assured.

Psychology, Health


Psychology has various definitions, most of them stating that psychology is the study of behavior. Health psychology is the application of psychology to health-related problems and behavior. Most psychological applications in health are from the discipline of social psychology. The contribution of health psychology to public health is in such areas as psychological processes in prevention, health maintenance (e.g., not smoking), and patient education, particularly in helping people cope with an illness (e.g., mastering the use of the peak flow meter to control asthma).


Health psychology deals with individual behavior in a social context. However, within the public health sector, behavior is not restricted to behavior of at-risk persons, but also includes behaviors of peers, parents, health professionals, employers, politicians, and others. Unfortunately, while there is a large amount of empirical data available regarding individual behavior of the at-risk person or patient, there is very little data available about behaviors at other social levels.

Health psychologists try to understand behavior by describing psychosocial determinants for individual behavior. But health psychologists also try to understand and promote behavior change. One basic assumption in health psychology is that to change people's behaviorat least through health promotion interventionsit is necessary to understand the psychosocial determinants of behavior. For example, when a smoker fails to stop smoking because of a lack of motivation, another type of intervention is required than for a smoker that fails because of a lack of social support.

The first public health applications of psychology were strongly focused on risk perception and risk taking. The best example may be the health belief model, where the perception of the severity of the risk and the susceptibility for the risk were seen as the primary determinants of health-protective behaviors. Over time, it became clear that people have many reasons for health-related behaviors, of which risk perception is often not an important one. In this multicausality approach, there is also a growing recognition of the many psychosocial and environmental influences on individual behavior. Changes in psychosocial determinants (e.g., self-efficacy) are most effective in creating behavior change when paralleled by changes in the social and physical environment(e.g., removal of barriers).

The application of psychological theories to public health is not without debate. Some professionals state that psychological theories will never be able to fully help us understand behavior and behavior change; other professionals claim that in practice there is nothing so helpful as a good theory. Both perspectives are justified. Theories are, by definition, a reduction of reality, but they do help people organize their thoughts and ask the right questions. The interesting contribution of theories is that they can generalize findings from one area of behavior to be of use in another.


The most often applied theories to explain the psychosocial determinants of behavior are Icek Ajzen's theory of planned behavior and Albert Bandura's social cognitive theory. Social cognitive theory (SCT) specifies the following determinants of behavior: outcome expectations, self-efficacy expectations, behavioral capability, perceived behavior of others (modeling), and the social and physical environment.

The theory of planned behavior (TPB) is an extension of the earlier theory of reasoned action. TPB postulates that intention, the most proximal determinant of behavior, is determined by three conceptually independent constructs: attitude, subjective norms, and perceived behavioral control (or self-efficacy). The attitude towards the behavior is determined by salient beliefs, or outcome expectations, about that behavior. Beliefs are weighted by evaluations or judgments about the value or importance of the expected outcome. For example, the expected outcome of going on a lowfat diet might be a lowering of blood pressure, which could be judged to be important and worthwhile.

Subjective norms, or perceived social expectations, are beliefs that specific, important individuals or groups approve or disapprove of the behavior. These beliefs are weighted by the motivation to comply with the referent person or groupthat is, how important is a friend's or group's approval or opinion. Note that Ajzen's perceived social expectations are different from Bandura's perceived behavior of others, where the social environment does not necessarily expect certain behavior. Other authors have broadened the TPB social influence construct to include perceived behavior of others, perceived expectations of others, social pressure, and social support.

Perceived behavior control or self-efficacy refers to the subjective probability that a person is capable of executing a certain action (e.g., going on a low-fat diet might be perceived to be difficult).

Since the theory of planned behavior was introduced in the 1980s, other determinants have been suggested, including: personal moral norms, anticipated regret, identity concerns, and self-evaluation. Another development is an increasing attention to the relation between intentions and behavior. Studies on implementation intention show that helping people to make plans to behave in a certain way can improve the intention-behavior link. Intentions, however, may be overruled by habits. Behaviors become habitual when performed frequently and when performed in a stable environment. Under conditions where habits conflict with intentions, intentions become poor predictors of behavior. It is possible, however, to break bad habits by replacing a habitual sequence with an alternative sequence.

TPB is most often applied at the individual level. However, it has been applied to higher ecological levels as well, such as the voting behavior of legislators regarding a cigarette tax increase, or the adoption behavior of schoolteachers and principles for HIV (human immunodeficiency virus) prevention programs.


The most prominent psychology theories of behavior change are the social cognitive theory, James Prochaska and Carlo DiClemente's transtheoretical model, Richard Petty and John Cacioppo's elaboration likelihood model, and various theories on coping and self-regulation by authors like Richard Lazarus. Social cognitive theory suggests the following methods for change: active learning, reinforcement, and modeling and guided practice (including feedback).

The transtheoretical model (TTM) has two major sets of constructs: stages of change and processes of change. In the stages of change, people are thought to move from a state of no motivation to change to one of internalization of new behavior. The first stage is "precontemplation," in which people have no intention to change their behavior. In a successful change process, people make a transition to "contemplation," in which they are thinking about changing the problem behavior. Ideally, people then move to "preparation," in which they are planning to change this behavior in the short term. People who have recently changed their behavior are in the "action stage," whereas people who have performed the behavior for a longer time are in the "maintenance stage." People in the action stage may lapse and then recycle to an earlier stage.

TTM can be used to describe and to change behavior. An important contribution of the model is the specific tailoring of educational efforts to include different models and processes of change for individuals in different stages of change. For instance, a re-evaluation of outcome expectations is used to make the change from precontemplation to contemplation; and a guided practice for skills improvement can help with the change from action to maintenance.

Social psychology has a long tradition in persuasion research. Petty and Cacioppo have a new perspective on persuasion effects with their elaboration likelihood model (ELM). The basic idea of ELM is that people differ in their ability and motivation for thoughtful information processing of persuasive messages. These authors explain two ways of information processing, central or peripheral (also called systematic versus heuristic). Central processing occurs when a message is carefully considered and compared against other messages and beliefs. Peripheral processing occurs when a message is processed without thoughtful consideration or comparison. A variablefor instance, the credibility of a sports hero as a modelmay have a positive effect when the receivers process the message through the peripheral route, but a negative effect when they follow the central route, because people might realize that their behavioral capabilities are different from those of the sports hero. Research findings suggest that thoughtful information processing is related to a higher persistence of attitude change, a higher resistance to counter-persuasion, and a stronger attitudebehavior consistency. ELM suggests two ways to stimulate central processing: Make the message more personally relevant and unexpected, and repeat the message.

Self-regulatory or self-management conceptualizations, including coping theories, have to do with how individuals function to behaviorally self-correct. Various authors describe this process. The general procedure is: (a) monitoring of some aspect of behavior or health, (b) comparing one's observation with normal or desired outcomes or behavior, describing a problem or divergence from normal, and analyzing the causes of the problem, and (c) trying a behavioral correction. This entire process recycles with a return to monitoring. Self-regulatory theories are useful for the designation of health-promoting behaviors for the self-management of chronic diseases, such as asthma, diabetes, or cystic fibrosis.

Clinical Psychology

Clinical psychology

The application of psychological principles to diagnosing and treating persons with emotional and behavioral problems.

Clinical psychologists apply research findings in the fields of mental and physical health to explain dysfunctional behavior in terms of normal processes. The problems they address are diverse and include mental illness , mental retardation , marital and family issues, criminal behavior, and chemical dependency. The clinical psychologist may also address less serious problems of adjustment similar to those encountered by the counseling psychologist.

Approximately one-third of the psychologists working in the United States today are clinical psychologists. A number of clinical psychologists are in private practice, either alone or in group practice with other mental health professionals. Others may practice in a variety of settings, including community mental-health centers, university medical schools, social work departments, centers for the mentally and physically handicapped, prisons, state institutions and hospitals, juvenile courts, and probation offices. Clinical psychologists use psychological assessment and other means to diagnose psychological disorders and may apply psychotherapy to treat clients individually or in groups. In the United States, they are governed by a code of professional practice drawn up by the American Psychological Association .

Individuals consult clinical psychologists for treatment when their behaviors or attitudes are harmful to themselves or others. Many different treatment types and methods are employed by psychologists, depending on the setting in which they work and their theoretical orientation. The major types of therapy include psychodynamic therapies, based on uncovering unconscious processes and motivations, of which the most well known is Freudian psychoanalysis ; phenomenological, or humanistic, therapies (including the Rogerian and Gestalt methods) which view psychotherapy as an encounter between equals, abandoning the traditional doctor-patient relationship; and behavior-oriented therapies geared toward helping clients see their problems as learned behaviors that can be modified without looking for unconscious motivations or hidden meanings. These therapies, derived from the work of Ivan Pavlov and B.F. Skinner , include methods such as behavior modification and cognitive-behavior therapy, which may be used to alter not only overt behavior but also the thought patterns that drive it.

The work of the clinical psychologist is often compared with that of the psychiatrist, and although there is overlap in what these professionals do, there are also specific distinctions between them. As of 1996, clinical psychologists cannot prescribe drugs to treat psychological disorders, and must work in conjunction with a psychiatrist or other M.D. who is authorized to administer controlled substances. However, a movement is under-way for prescription privileges for psychologists. The clinical psychologist has extensive training in research methods and in techniques for diagnosing, treating, and preventing various disorders. Most psychologists earn a Ph.D. degree in the field, which requires completion of a four- to six-year program offered by a university psychology department. The course of study includes a broad overview of the field (including courses in such areas as statistics, personality theory, and psychotherapy), as well as specialization in a particular subfield and completion of a practicum, internship, and dissertation.

A new training program for psychologists was developed and introduced at the University of Illinois, which offered the first Psychology Doctorate (Psy.D.) in 1968. This degree program is geared exclusively toward the training of clinicians rather than researchers. It stresses course work in applied methods of assessment and intervention and eliminates the dissertation requirement. The number of Psy.D. programs in the United States has grown since 1968, with some programs offered at universities and others at independent, "freestanding" professional schools of psychology.

Assessment plays a prominent role among the functions of clinical psychology. The term "clinical psychology" itself was first used at the end of the nineteenth century in connection with the testing of mentally retarded and physically handicapped children. The discipline soon expanded with the growing interest in the application of assessment techniques to the general population following Robert Yerkes's revision of the Stanford Binet Intelligence scales in 1915, creating a widely used point scale for the measurement of human mental ability . Clinical psychologists must be familiar with a variety of techniques of assessing patients through interviews, observation, tests, and various forms of play . Assessment may be used to compare an individual with others in a reliable way using standardized norms; determine the type and circumstances of symptomatic behaviors; understand how a person functions in a given area (cognition , social skills, emotion ); or match a patient to a particular diagnostic category for further treatment.

While the clinical psychologist does not specialize in research, the two disciplines often overlap. With their varied experiences, clinicians are qualified to participate in research on, for example, cost effectiveness in health care, design of facilities, doctor-patient communication, or studies of various treatment methods. Clinical psychologists routinely contribute to the training of mental health professionals and those in other areas of health care, serving on the faculties of universities and independent institutes of psychology, where they teach courses, supervise practicums and internships, and oversee dissertation research. They also carry out administrative appointments which call for them to assist in the planning and implementation of health care services and are represented in international groups such as the World Health Organization.

Health Psychology

Health psychology

A subfield of psychology devoted to health maintenance, including research on the relationship between mental and physical health, guidance in improving individual health through lifestyle changes, and analysis and improvement of the health care system.

Health psychology is a diverse area with a variety of emphases. Medical psychology focuses on the clinical treatment of patients with physical illnesses, offering practical advice people can use in order to improve their health. While there is special emphasis on psychosomatic disordersthose that have traditionally been most closely related to psychological factorsthe current trend is toward a holistic perspective that considers all physical health inseparable from a patient's emotional state. As part of this trend, psychologists and pediatricians have joined forces in the growing area of pediatric psychology, collaborating to meet the health and developmental needs of children and their families. Another focal point is rehabilitation psychology, which teams mental health professionals with health care providers who care for patients with physical disabilities and chronic conditions, often in institutional settings.

Another province of health psychology is the study of "health behavior"how people take care of or neglect their health, either in a preventative context or when they are ill. This area includes such concerns as drug abuse, utilization of health care resources, and adjustment to chronic illness. Health psychology also addresses the health care system itself, including analysis of the outreach, diagnostic, and prescription processes, provider-patient interaction, and the training of health care personnel.

clinical sociology

clinical sociology A term, analogous to clinical psychology, introduced in 1931 by Chicago sociologist Louis Wirth, for the work of sociologists employed in clinical settings alongside social workers, psychologists, and psychiatrists. Clinical sociology involves the use of sociological knowledge to aid diagnosis, treatment, teaching, and research. However, the practice of employing clinical sociologists is not widespread.
