Supplementary material from "Social reward questionnaire: adolescent version and its association with callous–unemotional traits"

However, no measure of social reward value exists for this age group. In this study, we adapted the adult Social Reward Questionnaire, which we had previously developed and validated, for use with adolescents.

Participants aged 11–16 ( n = 568; 50% male) completed the Social Reward Questionnaire—Adolescent version (SRQ-A), alongside measures of personality traits—five-factor model (FFM) and callous–unemotional (CU) traits—for construct validity purposes. A confirmatory factor analysis of the SRQ-A supported a five-factor structure (Comparative Fit Index = 0.90; Root Mean Square Error of Approximation = 0.07), equating to five questionnaire subscales: enjoyment of Admiration, Negative Social Potency, Passivity, Prosocial Interactions and Sociability.
