Despite practice guidelines recommending caregiver inclusion for assessment of mental health problems in adolescents, clinical high-risk (CHR) assessment tools that target attenuated psychosis symptoms rely solely on self-report. As many individuals in the clinical high-risk phase are expected to be adolescents, and programs of CHR research routinely recruit participants as young as twelve, parent input regarding adolescents%26apos; symptoms and functioning may help to inform clinical conceptualizations. No assessment tool targeting CHR symptoms has been developed for this purpose. We created a caregiver-report version of the 12-item Prime Screen-Revised and administered the measure to caregivers of 52 youth ages 12-19 referred by mental health providers for CHR study participation. Youth completed the Prime Screen-Revised as well as the Structured Interview for Psychosis Risk Syndromes (SIPS). Caregiver responses demonstrated poor agreement with youth ratings on Prime Screen-Revised (r = .09), but moderate agreement with clinician ratings (r = .41). The addition of caregiver screening data to youth self-report scores significantly improved a linear regression predicting clinician ratings. Using a threshold of four or more endorsements, the combined use of parent and adolescent responses accurately classified 75% of respondents with regard to SIPS-determined CHR status. Findings suggest that involving caregivers may help to improve the specificity of CHR screening and assessment procedures.
