Self-Disorders and Clinical High Risk for Psychosis: An Empirical Study in Help-Seeking Youth Attending Community Mental Health Facilities

Anomalous subjective experiences involving an altera- tion of the basic sense of self (ie, Self-disorder [SD]) are emerging as a core marker of schizophrenia spec- trum disorders with potential impact on current early detection strategies as well. In this study, we wished to field-test the prevalence of SD in a clinical sam- ple of adolescent/young adult help-seekers at puta- tive risk for psychosis attending standard community mental health facilities in Italy. Participants (n = 47), aged between 14 and 25, underwent extensive psycho- pathological evaluations with current semi-structured tools to assess Clinical High Risk (CHR) state (ie, Structured Interview for Prodromal Syndromes/Scale of Prodromal Symptoms [SIPS/SOPS], Schizophrenia Proneness Instrument-Adult/Child and Youth [SPI-A/ CY]). SD aggregated in CHR subjects as compared to the non-CHR and revealed substantial association with sub-psychotic symptoms (SIPS), subjective expe- rience of cognitive and cognitive-perceptual vulner- ability (basic symptoms) and functional level (Global Assessment of functioning). Moreover, a combination of the 2 approaches (ie, CHR plus SD) enabled further “closing-in” on a subgroup of CHR with lower global functioning. The results confirm SD’s relevance for the early profiling of youths at potential high risk for psychosis.
