Introduction This database includes the raw data linked with the paper “Perceived family functioning profile in adolescents at Clinical High-Risk for Psychosis: rigidity as a possible preventive target”, currently under submission. In this paper, we reported sociodemographic characteristics, family history of any DSM-5 psychiatric disorder, personal history of any DSM-5 psychiatric disorder, psychopathological assessment, and level of functioning. We aimed at investigating the role of family functioning for APS adolescents compared to adolescents suffering from early onset psychosis and with other psychiatric disorders. Methods Participants were then divided into three groups: 1) adolescents with established Early Onset Psychosis (EOP), 2) adolescents meeting DSM-5 Attenuated psychotic Syndrome (APS) criteria and the attenuated psychotic symptoms subgroup of the Clinical High Risk for Psychosis (CHR-P), 3) adolescents with other DSM-5 psychiatric disorders who did not meet APS/EOP criteria. Results Our results suggest that family functioning has a central role and could represent a worthwhile target of intervention for adolescents at CHR-P, leading the way to new preventive approaches.
