30. Diminished anticipatory pleasure in individuals at clinical high-risk for psychosis using ecological momentary assessment

Schizophrenia has been associated with a deficit in anticipatory but not consummatory pleasure; however, it is unclear if this pattern also holds in individuals at clinical high-risk (CHR) for psychosis. The current study evaluated anticipatory and consummatory pleasure and negative emotion in the context of everyday life, using ecological momentary assessment (EMA). Participants included CHR individuals and healthy controls who completed 6 days of EMA, which consisted each day of 8 in-the-moment surveys and 1 event survey in relation to a planned pleasurable activity (PPA). Analyses evaluated EMA survey items which probed for anticipatory and consummatory positive and negative emotion in relation to the PPA. Results indicated that CHR completed fewer PPAs than controls. Similar to what is observed in schizophrenia, CHR had a reduction in anticipatory but not consummatory pleasure. CHR also reported more anticipatory and consummatory negative affect than controls. In controls, consummatory but not anticipatory pleasure predicted the probability of completing the PPA, whereas neither anticipatory nor consummatory pleasure predicted probability of completing the PPA in CHR. These findings suggest that, similar to individuals diagnosed with schizophrenia, anhedonia is present in CHR participants, and is best characterized as a deficit in anticipatory rather than consummatory pleasure.
