ABSTRACT
Social anhedonia is considered a key feature of schizophrenia that leads to impaired social functioning. Although traditional laboratory measures assess non-current social pleasure, researchers have begun using experience sampling methods (ESM) to measure current, or consummatory, experiences of social pleasure in daily life. A recent meta-analysis examined deficits in consummatory social pleasure in schizophrenia and found vast heterogeneity in effect sizes across ESM studies. Thus, this meta-analysis aimed to extend those results by testing moderators of this effect. Meta-analysis of 14 ESM studies suggests those with psychotic disorders exhibit a moderate deficit in consummatory social pleasure compared to healthy controls. Yet, this effect was significantly moderated by the type of measure used to assess social pleasure. Measures that directly assessed positive emotional experience during socialization yielded small effects that failed to reach significance; indirect measures of other social factors related to pleasure yielded large, significant effects. This suggests daily social anhedonia observed in psychotic disorders is not due to reduced experience of positive emotion. Instead, social anhedonia may be driven by other elements of social functioning. Most clinical variables did not influence effects, but there was a trend such that patient groups with lower cognitive functioning exhibited greater pleasure deficits. Inconsistent reporting across studies limited our ability to examine other real-world variables that may contribute to deficits in social pleasure. Yet, results show different ESM items used to measure social pleasure do not assess the same construct. Future research is needed to validate ESM measures and standardize protocols across studies.
