Daily stress and emotions in relation to fear of negative and positive evaluation.

Fear of negative (FNE) and positive (FPE) evaluation constitute distinct components of social anxiety and relate to altered affectivity. It is unclear whether individuals with strong FNE/FPE overreact to social stressors only or to more unspecific ones as well. The present set of three studies (n = 109 and n = 97 healthy individuals in study 1/2, n = 49 patients with social anxiety disorder in study 3) assessed whether reactivity to various daily stressors and non-specific momentary stress/emotions assessed through ecological momentary assessment depend on individuals' level of FPE/FNE. Almost all relationships with FPE/FNE were explained by depressive symptoms, except for a unique association of FNE with reactivity to stressors from the distant social network. Relationships of FNE with momentary global stress and emotions were mixed, but again explained by depressive symptoms. More depressive symptoms were associated with higher stress, negative affect, and most stressor types as well as lower positive affect in all studies. These results show that for social stressors from the distant social network, FNE has explanatory power. They further document the role of depressive affect for reactivity to a wide range of everyday stressors and question the need for specific instruments assessing FPE/FNE unless stressors are explicitly social-evaluative in nature.
