Consummatory deficits in close social reward predict inflammation-induced depressed mood.

ABSTRACT:

Background

Inflammation is implicated in the etiology of depression, but not all individuals develop mood symptoms when exposed to inflammatory states. Identifying psychological predictors of this vulnerability is critical for advancing mechanistic models of depression. Deficits in global reward processing predict risk for depression, but reward processing involves both temporal dimensions (e.g., anticipatory vs. consummatory pleasure) and experiential domains (e.g., social vs. non-social). It remains unknown whether specific aspects of reward experience predict greater affective sensitivity to inflammation. This study examined whether lower in-the-moment and anticipated enjoyment across multiple reward domains in daily life predicted greater increases in depressed mood following a
