Excessive or complex polypharmacy (≥4 psychotropics) has been studied in patients with bipolar disorder, but not in schizophrenia to date. Methods: We conducted a digital medical record data extraction of 829 patients consecutively admitted to a psychiatric hospital and diagnosed as having schizophrenia-spectrum disorders. Results: In those prescribed psychiatric medication preadmission, 28.1% (n = 169) met the criteria for complex polypharmacy. Complex polypharmacy patients were older, female, white, and disabled, and had more comorbidities compared with those without complex polypharmacy. In multivariable analysis, complex polypharmacy was specifically associated with being white and disabled, and having a comorbid anxiety disorder, tobacco use disorder, metabolic condition, and neurological condition compared with noncomplex polypharmacy patients. Conclusions: Although there is little evidence to support complex polypharmacy in schizophrenia, rates were relatively high in patients requiring hospitalization, especially when they are also diagnosed as having comorbid psychiatric and medical conditions. Future research is needed to study the risk-benefit profile for these patients, especially considering their higher medical burden and related health risks.

We surveyed adults (N = 2510) from February to March 2021 across five sites (Australia = 502, Germany = 516, Hong Kong = 445, UK = 512, USA = 535) using a cross-sectional design and stratified quota sampling for age, sex, and education. We assessed willingness to take a vaccine and a comprehensive set of putative predictors. Predictive power was analysed with regression analyses and machine learning algorithms. Only 57.4% of the participants indicated that they would definitely or probably get vaccinated. A parsimonious machine-learning model could identify vaccine hesitancy with high accuracy (i.e. 83% sensitivity and 82% specificity) using 10 variables only. The most relevant predictors were vaccination conspiracy beliefs, paranoid concerns related to the pandemic, COVID anxiety, high perceived risk of infection, low perceived social rank, lower age, and female gender. Campaigns seeking to increase ...

The current study investigated the psychometric properties and clinical usefulness of a new measure called the Self-Efficacy for Social Situations (SESS) Scale. Results provide preliminary evidence for the reliability and validity of the

The authors identified 50 top-selling self-help books for anxiety, depressive, and trauma-related disorders. Using a scale derived from the literature on bibliotherapy, expert psychologists rated each book on overall usefulness, grounding in psychological science, the extent to which it offers reasonable expectations, the extent to which it offers specific guidance for implementing the self-help techniques and for monitoring treatment progress, and whether it offers potentially harmful advice. The results revealed strong intercorrelations among the scales, such that books scoring high along one dimension tended to score high along others. There was wide variability in the overall quality of the books, but several factors emerged as predictors of book quality. The most highly rated books tended to be those having a cognitive behavioral perspective, those written by mental health professionals, those written by authors holding a doctoral degree, and those focusing on specific problems. Implications of the findings, including specific recommendations for authors and consumers of self-help books, are discussed.

Thirty-two clinical psychologists evaluated 12 profiles of hypothetical patients in which these factors were varied factorially. The results revealed strong effects of typicality and dominance, but no effects for number. Implications for the assessment and classification of personality disorders are discussed. Recent years have witnessed a growing interest in the classification of personality disorders. Most current nosological systems, including recent editions of the Diagnostic and Statistical Manual of Mental Disorders (DSM; American Psychiatric Association, 1980, 1987, 1994) are rooted largely in classical models of categorization. If all members of a classical category possess the same set of necessary and sufficient features, it follows that all category members are equally good and representative instances of the category, and equally poor and unrepresentative examples of other categories. According to the classical model, category membership is inherently clear-cut, with homogeneity within categories, clearly demarcated boundaries, and heterogeneity between categories. These assumptions, however, do not reflect the more complex reality of many psychological concepts. Such models, in which a list of necessary and sufficient criteria define category membership, have been found to be problematic in relation to many psychological concepts, including the personality disorders (Cantor & Mischel, 1977; Lakoff, 1987; Rosch, 1973, 1978). The personality disorders defy the assumptions of classical categorization in several ways. These include the high degree of heterogeneity within each disorder, the fact that 95
