The Social Cognition and Object Relations Scale-Global Version (SCORS-G) is a clinical rating system assessing 8 domains of self- and interpersonal relational experience that can be applied to narrative response data (e.g., Thematic Apperception Test [TAT; Murray, 1943], early memories narratives) or oral data (e.g., psychotherapy narratives, relationship anecdotal paradigms). In this study, 72 psychiatrically hospitalized adolescents consented and were rated by their individual and group therapist using the SCORS-G. Clinicians also rated therapy engagement, personality functioning, quality of peer relationships, school functioning, global assessment of functioning (GAF), history of eating-disordered behavior, and history of nonsuicidal self-injury. SCORS-G composite ratings achieved an acceptable level of interrater reliability and were associated with theoretically predicted variables (e.g., engagement in therapy, history of nonsuicidal self-injury). SCORS-G ratings also incrementally improved the prediction of therapy engagement and global functioning beyond what was accounted for by GAF scores. This study further demonstrates the clinical utility of the SCORS-G with adolescents.
