Borderline Personality Features among Individuals at Clinical High Risk for Psychosis (CHR‐P): A Brief Report

Aim This exploratory study reports on borderline symptomatology within a sample of individuals at clinical high risk for psychosis (CHR-P) through a validated, self-report instrument, the short version of the Borderline Symptom List (BSL-23). Methods The sample consisted of 44 help-seeking CHR-P youth (ages 14-29 years) who completed an initial evaluation at a specialized clinic for psychosis-risk. Results The mean BSL-23 score was 1.5 (SD = 1.0, range 0.1-4.0). Higher scores were strongly associated with greater reported depressive symptoms (r = 0.84, p < 0.001). Additionally, borderline symptoms associated with attenuated positive symptoms (r = 0.32, p = 0.034) and social anxiety (r = 0.34, p = 0.027). Borderline symptomatology was not associated with role or social functioning. Conclusions This study is one of the first examinations of borderline symptomatology within a CHR-P sample through a validated self-report measure. Future research replicating these results is required to determine their robustness.
