The assessment of intervention competence possesses an obvious relevance for practitioners and clinical scientists alike. It is often assessed as part of the evaluation of treatment integrity in clinical research in general, and in randomized clinical trials (RCTs) in particular. The authors first attempt to add clarity to the concept and better differentiate intervention competence from closely related constructs. Next, the authors review and evaluate the main measures of therapist competence used in RCTs, relying on this conceptual foundation to provide suggestions for future measures. The empirical literature on the relation between therapist competence and clinical outcome is then reviewed. The relation, while positive, is weaker than expected, and factors having a potential bearing on this are discussed. The authors then recommend that new measures be created and that the assessment of limited-domain competence be supplemented by explorations of global competence. Due to the potential ramifications for the field, the authors also recommend that caution be exercised in the task of operationally defining competence.

Objective To determine lifetime prevalence rates of sleep paralysis. Data Sources Keyword term searches using “sleep paralysis”, “isolated sleep paralysis”, or “parasomnia not otherwise specified” were conducted using MEDLINE (1950-present) and PsychINFO (1872-present). English and Spanish language abstracts were reviewed, as were reference lists of identified articles. Study Selection Thirty five studies that reported lifetime sleep paralysis rates and described both the assessment procedures and sample utilized were selected. Data Extraction Weighted percentages were calculated for each study and, when possible, for each reported subsample. Data Synthesis Aggregating across studies (total N = 36533), 7.6% of the general population, 28.3% of students, and 31.9% of psychiatric patients experienced at least one episode of sleep paralysis. Of the psychiatric patients with panic disorder, 34.6% reported lifetime sleep paralysis. Results also suggested that minorities experience lifetime sleep paralysis at higher rates than Caucasians. Conclusions Sleep paralysis is relatively common in the general population and more frequent in students and psychiatric patients. Given these prevalence rates, sleep paralysis should be assessed more regularly and uniformly in order to determine its impact on individual functioning and better articulate its relation to psychiatric and other medical conditions.

Through the course of this paper we discuss several fundamental issues related to the intervention competence of psychologists. Following definitional clarification and proposals for more strictly distinguishing competence from adherence, we interpret Dreyfus and Dreyfus's (1986) five stage theory of competence development (from novice to expert) within a strictly clinical framework. Existing methods of competence assessment are then evaluated, and we argue for the use of new and multiple assessment modalities. Next, we utilize the previous sections as a foundation to propose methods for training and evaluating competent psychologists. Lastly, we discuss several potential impediments to large scale competence assessment and education, such as the heterogeneity of therapeutic orientations and what could be termed a lack of transparency in clinical training.The idea of psychological competence has recently assumed a prominent role in our field. Competencies of various sorts (e.g., research, teaching, assessment) have been widely discussed (e.g, Kaslow, 2004), and recent work has attempted to formalize these multifarious competencies into a widely-known "cube model" (Rodolfa et al., 2005). However, many questions about competence remain unanswered, and these include several which are fundamental (e.g., what competence means, how best to measure it, and how to it develops). This current lack of firm answers is likely due to the number of central theoretical issues that underlie the construct of competence as well as the assortment of psychological approaches that are currently available.Clinical psychology and the services it provides represent a principal locus where psychological knowledge and the general public converge in an intimate way. As the public is continually searching for a means to ensure that its time and money are invested in trusted and competent sources, the idea of intervention competence (or that particular type of competence demonstrated when remedying psychological difficulties) holds an obvious relevance. This is especially the case given that accountability has recently become something of a cause celebre (e.g., Nelson, 2007). Thus, given this importance, we intend to review the many complexities involved in understanding intervention competence. It is important to note that Correspondence to: Brian A. Sharpless.

This review summarizes the empirical and clinical literature on sleep paralysis most relevant to practitioners. During episodes of sleep paralysis, the sufferer awakens to rapid eye movement sleep-based atonia combined with conscious awareness. This is usually a frightening event often accompanied by vivid, waking dreams (ie, hallucinations). When sleep paralysis occurs independently of narcolepsy and other medical conditions, it is termed “isolated” sleep paralysis. Although the more specific diagnostic syndrome of “recurrent isolated sleep paralysis” is a recognized sleep–wake disorder, it is not widely known to nonsleep specialists. This is likely due to the unusual nature of the condition, patient reluctance to disclose episodes for fear of embarrassment, and a lack of training during medical residencies and graduate education. In fact, a growing literature base has accrued on the prevalence, risk factors, and clinical impact of this condition, and a number of assessment instruments are currently available in both self-report and interview formats. After discussing these and providing suggestions for accurate diagnosis, differential diagnosis, and patient selection, the available treatment options are discussed. These consist of both pharmacological and psychotherapeutic interventions which, although promising, require more empirical support and larger, well-controlled trials.

Isolated sleep paralysis (ISP) has received scant attention in clinical populations, and there has been little empirical consideration of the role of fear in ISP episodes. To facilitate research and clinical work in this area, the authors developed a reliable semistructured interview (the Fearful Isolated Sleep Paralysis Interview) to assess ISP and their proposed fearful ISP (FISP) episode criteria in 133 patients presenting for panic disorder treatment. Of these, 29.3% met lifetime ISP episode criteria, 20.3% met the authors’ lifetime FISP episode criteria, and 12.8% met their recurrent FISP criteria. Both ISP and FISP were associated with minority status and comorbidity. However, only FISP was significantly associated with posttraumatic stress disorder, body mass, anxiety sensitivity, and mood and anxiety disorder symptomatology.

Objective The contributions of disorder severity, comorbidity and interpersonal variables to therapists’ adherence to a cognitive–behavioural treatment (CBT) manual were tested. Method Thirty-eight patients received panic control therapy (PCT) for panic disorder. Trained observers watching videotapes of the sixth session of a 24-session protocol rated therapists’ adherence to PCT and their use of interventions from outside the CBT model. Different observers rated patients’ behavioural resistance to therapy in the same session using the client resistance code. Interview measures obtained before treatment included the Panic Disorder Severity Scale, the anxiety disorders interview schedule for Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV and the structured clinical interview for DSM-IV, Axis II. Questionnaire measures were the anxiety sensitivity index at intake, and, at session 2, the therapist and client versions of the working alliance inventory—short form. Results The higher the patients’ resistance and the more Axis II traits a patient had, the less adherent the therapist. Moreover, the more resistant the client, the more therapists resorted to interventions from outside the CBT model. Stronger therapist and patient alliance was also generally related to better adherence, but these results were somewhat inconsistent across therapists. Pretreatment disorder severity and comorbidity were not related to adherence. Conclusions Interpersonal variables, particularly behavioural resistance to therapy, are related to therapists’ ability to adhere to a treatment manual and to their use of interventions from outside of the CBT model.
