Abstract
We investigated the prevalence of persecutory, grandiose, reference, control, and religious delusions in adult clinical populations worldwide and whether they differed according to country characteristics or age, gender, or year of publication. 123 studies met inclusion criteria, across 30 countries; 102 (115 samples, n = 20,979) were included in the main random-effects meta-analysis of studies measuring multiple delusional themes (21 in a separate analysis of studies in recording a single theme). Persecutory delusions were most common (pooled point estimate: 64.5%, CI = 60.6–68.3, k = 106, followed by reference (39.7%, CI 34.5–45.3, k = 65), grandiose (28.2, CI 24.8–31.9, k = 100), control 21.6%, CI 17.8–26.0, k = 53), and religious delusions 18.3%, CI 15.4–21.6, k = 50). Data from studies recording one theme were broadly consistent with these findings. There were no effects for study quality or publication date. Prevalences were higher in samples exclusively with psychotic patients but did not differ between developed and developing countries, or by country individualism, power distance, or prevalence of atheism. Religious and control delusions were more prevalent in countries with higher income inequality. We hypothesize that these delusional themes reflect universal human dilemmas and existential challenges.
期刊介绍:
Clinical Psychology Review serves as a platform for substantial reviews addressing pertinent topics in clinical psychology. Encompassing a spectrum of issues, from psychopathology to behavior therapy, cognition to cognitive therapies, behavioral medicine to community mental health, assessment, and child development, the journal seeks cutting-edge papers that significantly contribute to advancing the science and/or practice of clinical psychology.
While maintaining a primary focus on topics directly related to clinical psychology, the journal occasionally features reviews on psychophysiology, learning therapy, experimental psychopathology, and social psychology, provided they demonstrate a clear connection to research or practice in clinical psychology. Integrative literature reviews and summaries of innovative ongoing clinical research programs find a place within its pages. However, reports on individual research studies and theoretical treatises or clinical guides lacking an empirical base are deemed inappropriate for publication.
