Annual Review of Clinical Psychology - Volume 1, 2005

Clinical psychology emerged as a profession in the United States in the 1890s with studies conducted by psychologists with patients in the mental asylums of that time, and with the founding of Witmer's psychological clinic, where he treated children with learning and behavioral problems. This chapter traces the history of clinical psychology as a profession, from the focus on assessment at the turn of the twentieth century to the provision of psychotherapy that would come to dominate the field after World War II. It concludes with a discussion of some of the contemporary concerns in the profession and how those might impact the future practice of clinical psychologists.

Because structural equation modeling (SEM) has become a very popular data-analytic technique, it is important for clinical scientists to have a balanced perception of its strengths and limitations. We review several strengths of SEM, with a particular focus on recent innovations (e.g., latent growth modeling, multilevel SEM models, and approaches for dealing with missing data and with violations of normality assumptions) that underscore how SEM has become a broad data-analytic framework with flexible and unique capabilities. We also consider several limitations of SEM and some misconceptions that it tends to elicit. Major themes emphasized are the problem of omitted variables, the importance of lower-order model components, potential limitations of models judged to be well fitting, the inaccuracy of some commonly used rules of thumb, and the importance of study design. Throughout, we offer recommendations for the conduct of SEM analyses and the reporting of results.

When clinical psychologists make judgments, are they likely to be correct or incorrect? The following topics are reviewed: (a) methodological advances in evaluating the validity of descriptions of personality and psychopathology, (b) recent findings on the cognitive processes of clinicians, and (c) the validity of judgments and utility of decisions made by mental health professionals. Results from research on clinical judgment and decision making and their relationship to conflicts within the field of clinical psychology are discussed.

Motivational interviewing (MI) is a client-centered, directive therapeutic style to enhance readiness for change by helping clients explore and resolve ambivalence. An evolution of Rogers's person-centered counseling approach, MI elicits the client's own motivations for change. The rapidly growing evidence base for MI is summarized in a new meta-analysis of 72 clinical trials spanning a range of target problems. The average short-term between-group effect size of MI was 0.77, decreasing to 0.30 at follow-ups to one year. Observed effect sizes of MI were larger with ethnic minority populations, and when the practice of MI was not manual-guided. The highly variable effectiveness of MI across providers, populations, target problems, and settings suggests a need to understand and specify how MI exerts its effects. Progress toward a theory of MI is described, as is research on how clinicians develop proficiency in this method.

As high-profile reviews have appeared and international interest has grown, sophisticated studies of the U.S. population continue to document racial and ethnic disparities in initiation of mental health care and in continuity of care. Many explanations focus on cultural factors: trust and treatment receptiveness, stigma, culturally distinctive beliefs about mental illness and mental health, culturally sanctioned ways of expressing mental health–related suffering and coping styles, and client preferences for alternative interventions and treatment-seeking pathways, as well as unresponsive programs and providers. The research itself has become more rigorous and informative, but it continues to lack theoretical focus and does not yet yield cumulative findings. Too few studies have addressed community and regional differences or differences between mental health treatment programs and systems, or considered mental health-related policies that are very likely linked to disparities. Theoretically well-formulated studies on representative samples can provide a comprehensive explanation of access disparities in cultural and culture-related terms that inform a broad-based plan of remedial intervention.

A review of recent research on cognitive processing indicates that biases in attention, memory, and interpretation, as well as repetitive negative thoughts, are common across emotional disorders, although they vary in form according to type of disorder. Current cognitive models emphasize specific forms of biased processing, such as variations in the focus of attention or habitual interpretative styles that contribute to the risk of developing particular disorders. As well as predicting risk of emotional disorders, new studies haveprovided evidence of a causal relationship between processing bias and vulnerability. Beyond merely demonstrating the existence of biased processing, research is thus beginning to explore the cognitive causes of emotional vulnerability, and their modification.

This chapter provides a review of recent empirical developments, current controversies, and areas in need of further research in relation to factors that are common as well as specific to the etiology and maintenance of panic disorder, phobias, and generalized anxiety disorder. The relative contribution of broad risk factors to these disorders is discussed, including temperament, genetics, biological influences, cognition, and familial variables. In addition, the role that specific learning experiences play in relation to each disorder is reviewed. In an overarching hierarchical model, it is proposed that generalized anxiety disorder, and to some extent panic disorder, loads most heavily on broad underlying factors, whereas specific life history contributes most strongly to circumscribed phobias.

The dissociative disorders, including “psychogenic” or “functional” amnesia, fugue, dissociative identity disorder (DID, also known as multiple personality disorder), and depersonalization disorder, were once classified, along with conversion disorder, as forms of hysteria. The 1970s witnessed an “epidemic” of dissociative disorder, particularly DID, which may have reflected enthusiasm for the diagnosis more than its actual prevalence. Traditionally, the dissociative disorders have been attributed to trauma and other psychological stress, but the existing evidence favoring this hypothesis is plagued by poor methodology. Prospective studies of traumatized individuals reveal no convincing cases of amnesia not attributable to brain insult, injury, or disease. Treatment generally involves recovering and working through ostensibly repressed or dissociated memories of trauma; at present, there are few quantitative or controlled outcome studies. Experimental studies are few in number and have focused largely on state-dependent and implicit memory. Depersonalization disorder may be in line for the next “epidemic” of dissociation.

This review discusses neurobiological and psychosocial factors associated with stress-induced depression and compares these factors with those believed to characterize stress resilience. Neurobiological factors that are discussed and contrasted include serotonin, the 5-HT1A receptor, polymorphisms of the 5-HT transporter gene, norepinephrine, alpha-2 adrenergic receptors, neuropeptide Y, polymorphisms of the alpha-2 adrenergic gene, dopamine, corticotropin-releasing hormone (CRH), dehydroepiandrosterone (DHEA), cortisol, and CRH receptors. These factors are described in the context of brain regions believed to be involved in stress, depression, and resilience to stress. Psychosocial factors associated with depression and/or stress resilience include positive emotions and optimism, humor, cognitive flexibility, cognitive explanatory style and reappraisal, acceptance, religion/spirituality, altruism, social support, role models, coping style, exercise, capacity to recover from negative events, and stress inoculation. The review concludes with potential psychological, social, spiritual, and neurobiological approaches to enhancing stress resilience, decreasing the likelihood of developing stress-induced depression/anxiety, and treating stress-induced psychopathology.

Improved methods of assessment and research design have established a robust and causal association between stressful life events and major depressive episodes. The chapter reviews these developments briefly and attempts to identify gaps in the field and new directions in recent research. There are notable shortcomings in several important topics: measurement and evaluation of chronic stress and depression; exploration of potentially different processes of stress and depression associated with first-onset versus recurrent episodes; possible gender differences in exposure and reactivity to stressors; testing kindling/sensitization processes; longitudinal tests of diathesis-stress models; and understanding biological stress processes associated with naturally occurring stress and depressive outcomes. There is growing interest in moving away from unidirectional models of the stress-depression association, toward recognition of the effects of contexts and personal characteristics on the occurrence of stressors, and on the likelihood of progressive and dynamic relationships between stress and depression over time—including effects of childhood and lifetime stress exposure on later reactivity to stress.

Individuals with schizophrenia experience a range of cognitive deficits and associated dysfunctions in the neural systems that support cognitive processes. This chapter reviews the literature on disturbances in working memory, executive control, and episodic memory in schizophrenia. Advances in basic cognitive neuroscience are described to help explain the cognitive neuroscience of schizophrenia. For working memory in schizophrenia, evidence is reviewed regarding deficits in the verbal (phonological loop) and nonverbal (visual-spatial scratch pad) buffer systems as well as in the central executive function. In the domain of episodic memory, evidence is reviewed for deficits in recollection versus familiarity processes in episodic memory. Also discussed are conceptual issues and potential confounds relevant to understanding the cognitive neuroscience of schizophrenia, including the role that cognitive deficits play in the developmental course of schizophrenia, relationships to specific symptom domains, behavioral performance confounds, and medication influences on behavioral performance and brain function.

We review major categorical and dimensional models of personality pathology, highlighting advantages and disadvantages of these approaches. Several analytic and methodological approaches to the question of the categorical versus dimensional status of constructs are discussed, including taxometric analyses, latent class analyses, and multivariate genetic analyses. Based on our review, we advocate a dimensional approach to classifying personality pathology. There is converging evidence that four major domains of personality are relevant to personality pathology: neuroticism/negative affectivity/emotional dysregulation; extraversion/positive emotionality; dissocial/antagonistic behavior; and constraint/compulsivity/conscientiousness. Finally, we discuss how dimensional approaches might be integrated into the diagnostic system, as well as some of the major issues that must be addressed in order for dimensional approaches to gain wide acceptance.

In this review, we explore two aspects of the development of psychopathy. First, we examine what psychopathy looks like across time. Second, we ask where psychopathy comes from. Much recent empirical work supports the idea that psychopathy in childhood and adolescence looks much like psychopathy in adulthood. Research utilizing recently created juvenile psychopathy indices demonstrates that juvenile psychopathy can be assessed reliably and that the nomological network surrounding the construct is quite similar to the one around adult psychopathy. Juvenile psychopathy is robustly related to offending, other externalizing problems, low levels of Agreeableness and Conscientiousness, and deficits in emotional processing and inhibition. Juvenile psychopathy is also relatively stable across adolescence. Much less research has examined from whence psychopathy comes, although several theories are reviewed. We close with a discussion of recent objections to the downward developmental extension of psychopathy to juveniles and some suggestions for additional research.

Child maltreatment exemplifies a toxic relational environment that poses significant risks for maladaptation across biological and psychological domains of development. Research on child maltreatment can inform developmental theory, but more importantly, it can enhance the quality of clinical, legal, and policy-making decisions for maltreated children. This chapter addresses definitional, epidemiological, and etiological aspects of child maltreatment. A developmental psychopathology perspective is directed toward the discussion of the psychological and neurobiological sequelae of child maltreatment. Implications for prevention, intervention, and social policy are discussed, and recommendations for future research are proffered.

Manual-based cognitive behavior therapy (CBT) is presently the most effective treatment of bulimia nervosa. Its efficacy is limited, however. Different strategies for improving upon current manual-based CBT are discussed, including combining CBT with antidepressant medication, integrating CBT with alternative psychological therapies, and expanding the scope and flexibility of manual-based CBT. CBT is underutilized in clinical practice. Dissemination of evidence-based treatment is a priority. Research on anorexia nervosa is minimal. Effective treatments have yet to be developed, although the Maudsley method of family therapy has shown the most promise in the treatment of adolescents. The most commonly seen eating disorders in clinical practice are those classified as “eating disorder not otherwise specified.” With the exception of binge eating disorder (BED), however, they have been neglected by researchers. Several psychological therapies have been shown to be effective in treating BED. Controversy exists over whether treatment-specific effects have been identified. Whereas treatments have proved effective in eliminating binge eating and associated eating disorder psychopathology, achieving clinically significant weight loss remains a challenge.

Gender identity disorder entered the psychiatric nomenclature in the DSM-III in 1980. This article reviews three domains of empirical research on gender identity disorder in children and adolescents: diagnosis and assessment, associated psychopathology, and developmental trajectories.

Pathological alcohol use is a complex and costly problem. This chapter focuses on recent developments in the etiology of alcohol use disorders. Literature is reviewed from the fields of epidemiology, genetics, personality, neuropsychology, parenting, and social influences. In addition, theoretical models that describe pathways to the development of alcohol use disorders are presented. Particular emphasis is given to ways in which genetic, environmental, psychopharmacological, and personological literatures can inform one another.

Decision making is central to health policy and medical practice. Because health outcomes are probabilistic, most decisions are made under conditions of uncertainty. This review considers two classes of decisions in health care: decisions made by providers on behalf of patients, and shared decisions between patients and providers. Considerable evidence suggests wide regional variation exists in services received by patients. Evidence-based guidelines that incorporate quality of life and patient preferences may help address this problem. Systematic cost-effectiveness analysis can be used to improve resource allocation decisions. Shared medical decision making seeks to engage patients and providers in a collaborative process to choose clinical options that reflect patient preferences. Although some evidence indicates patients want an active role in making decisions, other evidence suggests that some patients prefer a passive role. Decision aids hold promise for improving individual decisions, but there are still few systematic evaluations of these aids. Several directions for future research are offered.
