46. POSITIVE AND NEGATIVE AFFECT AS PREDICTORS OF FUTURE SOCIAL BEHAVIOR IN SCHIZOTYPY
Technological advancements have created novel ways to measure social behavior and affect in real-world settings. Social functioning deficits exist across the psychosis spectrum, including schizotypy, and past research suggests that affect differently predicts future social behavior for individuals with mental illness. To understand mechanisms underlying social dysfunction, we examined if positive and negative affect predicted social behavior in individuals with and without schizotypy. Subjects wore the Electronically Activated Recorder for two days, and reported affect hourly. Multilevel modeling was used to test the role of schizotypy and affect on social behavior at a future time point. Results indicated that controls were more likely to later engage in social behavior when positive affect was higher, but variations in positive affect did not impact social engagement for those with schizotypy (γ = 5.16%, SE = 1.64, p = 0.002). Negative affect did not differently predict behavior for the two groups (γ = -0.98%, SE = 2.01, p = 0.323). Findings demonstrate that current positive affect does not motivate individuals with schizotypy to later engage in complex social behavior; this may relate to past findings that, unlike controls, individuals with schizotypy do not experience a boost in positive affect during complex social behavior.
