Development of a social emotional information processing assessment for adults (SEIP-Q).

An expanded self-report, vignette-based, questionnaire was developed to assess five components in a social emotional information processing model (SEIP: attribution, emotional response, response valuation, outcome expectancy, response efficacy, and response enactment), first in a population-based sample (n = 250) and, second in healthy control participants (n = 50) and in those with DSM-5 Intermittent Explosive Disorder (IED: n = 50). SEIP-Q vignettes depict, separately, both overtly aggressive and relationally aggressive as well as socially ambivalent scenarios. This expanded SEIP-Q assessment demonstrated good internal reliability, as well as convergent and discriminant validity, for all five SEIP components. IED participants differed from healthy controls in all SEIP-Q components. This expanded SEIP-Q assessment is thus proposed as a reliable and valid method for studying the various stages of SEIP in adult human subjects. Aggr. Behav. 43:47-59, 2017.
