Brief battery of the Social Cognition Psychometric Evaluation study (BB-SCOPE): Development and validation in schizophrenia spectrum disorders

Abstract

The aim of the present study was to develop an abbreviated social cognition (SC) battery for individuals with schizophrenia spectrum disorders (SSD) to reduce the heterogeneity of and increase the frequency of assessment of SC impairment. To this end, the present study utilized Item Response Theory to develop brief versions of SC tasks administered to individuals with SSD (n = 386) and individuals without a psychiatric diagnosis (n = 292) during the Social Cognition Psychometric Evaluation (SCOPE) Study. Seven brief measures of SC were evaluated (i.e., Ambiguous Intentions and Hostility Questionnaire [AIHQ], Bell Lysaker Emotion Recognition Task [BLERT], Penn Emotion Recognition Task, Reading the Mind in the Eyes Task, Hinting Task, Intentionality Bias Task, Relationships Across Domains Task), and the existing brief version of The Awareness of Social Inference Test was reviewed. Psychometric properties for each brief SC measure were evaluated and compared to the original measures. Based on psychometric properties and relationships with other measures of SC, neurocognition, and functioning, two brief tasks (AIHQ, BLERT) and the full-length Hinting task were recommended for inclusion in a brief battery of SC tasks from the SCOPE Study (BB-SCOPE). The resulting BB-SCOPE is efficient, with an estimated administration time of 15 min, and comprehensively assesses three domains of SC (i.e., attributional bias, emotion processing, theory of mind) to identify severe SC impairment. Scoring of BB-SCOPE is also straightforward and includes a recommended cut-point of 60 for identifying SC impairment.
