Predicting Social Motivation and Interactions in Schizophrenia: An Ecological Momentary Assessment Study

Area of Science:

• Psychiatry
• Clinical Psychology
• Social Neuroscience

Background:

• Social motivation deficits are a core feature of psychosis, impacting daily functioning.
• Previous research relied on lab settings, limiting ecological validity.
• Understanding real-world social motivation is crucial for effective interventions.

Purpose of the Study:

• To investigate real-time factors influencing social motivation in Veterans with psychosis.
• To assess the utility of ecological momentary assessment (EMA) for studying social motivation.

Main Methods:

• Utilized EMA with 82 Veterans with psychosis, collecting data via four daily electronic surveys for one week.
• Measured social activity, including appraisals of interactions, experienced enjoyment, and desire for future socialization.
• Examined predictors of desire for social interaction and subsequent social engagement.

Main Results:

• Increased social rewards and positive performance appraisals were linked to a greater desire for social interaction.
• These positive factors did not predict the actual number of subsequent social interactions.
• Hostile attributions were not associated with either the desire for or the occurrence of social interactions.

Conclusions:

• EMA is a valuable tool for capturing state-level changes in social motivation.
• Positive experiences and performance appraisals are significant, modifiable drivers of social motivation.
• Additional factors beyond immediate positive experiences likely influence actual social behavior in psychosis.
