Anticipated Pleasure and Displeasure for Future Social and nonsocial Events: A Scale Development Study

Abstract

Abstract Background and Hypothesis People with schizophrenia (SCZ) or schizotypal traits (ST) have difficulties in anticipating future pleasure and displeasure in social situations. However, no self-report scale has been developed to specifically capture these abilities. This study aimed to develop and validate the Social Affective Forecasting Scale (SAFS), and to examine how anticipated pleasure and displeasure are associated with ST and clinical symptoms in SCZ. Study Design Study 1 recruited a main sample of 666 college students and a validation sample of 927 college students to complete the SAFS and other measurements for anhedonia. Exploratory factor analysis (EFA), confirmatory factor analysis (CFA), parallel analysis, and measurement invariance analysis were conducted. Study 2 recruited 2655 college students, 47 people with SCZ and 47 matched controls to complete the SAFS. Correlation analysis, regression analysis, and independent t-tests were performed. Study Results Both EFA and CFA indicated a 4-factor model which was supported by parallel analysis in the validation sample. The SAFS showed good internal consistency, convergent validity, and strong invariance across sex. Interpersonal features of ST and negative symptoms in SCZ were associated with reduced anticipated pleasure for positive social events. Conclusions The SAFS appears to be a reliable scale for evaluating anticipated pleasure and displeasure for future social and nonsocial events, and can be applied to study social anhedonia in individuals with ST and individuals with SCZ.
