Abstract

Background: The absence of systematic psychosis screening within general mental health services contributes to substantial treatment delays and poor long-term outcomes for individuals with psychotic symptoms. We conducted a meta-analysis to estimate rates of subclinical psychotic symptoms for psychotic experiences (PE), clinical high-risk for psychosis syndrome (CHR-P), and psychotic disorders that were identified via studies screening treatment-seeking individuals. These rates can inform implementation recommendations for routine psychosis screening in general mental health settings.

Methods: PubMed and Web of Science databases were searched to identify empirical studies with information on PE, CHR-P, or psychotic disorder prevalence identified by screening inpatients and outpatients (age < 65 years) receiving general mental health care. PE was identified using threshold scores on validated self-reported questionnaires, and CHR-P and psychotic disorder were identified using gold-standard structured interview assessments. A meta-analysis of each outcome was conducted using the restricted maximum likelihood estimator method to assess effect sizes in a random effects model.

Results: The analyses included 41 independent samples (k = 32 outpatient, k = 2 inpatient, k = 7 combined settings) with a total of 25,751 patients (58% female, mean age: 24.1 years). PE prevalence was 44.3% (95% CI: 35.8-52.8%; 28 samples, n = 21,957); CHR-P prevalence was 26.4% (95% CI: 20.0-32.7%; 28 samples, n = 14,395); and psychotic disorder prevalence was 6.6% (95% CI: 3.3-9.8%; 32 samples, n = 20,371). Rates did not differ by sex, age, or setting type.

Conclusions: The high prevalence of psychotic symptoms in general mental health treatment settings underscores the need for early-detection psychosis screening. These base rates can be used to plan training and allocation of resources required to conduct psychosis assessments and build capacity for delivering interventions for CHR-P and early psychosis in non-specialty mental health treatment settings.
