Emotional response patterns during social threat in individuals with generalized social anxiety disorder and...

Patterns of synchrony in repeated measures of heart rate, skin conductance levels, negative affect, and positive affect were investigated in patients with social anxiety disorder and non-anxious controls during a speech task. Despite expected low levels of absolute concordance between measures of affect and arousal overall, results revealed clearly defined and specific patterns of emotional response coherence that distinguished between the two groups and depended on the types of measures used. Specifically, findings demonstrated that (a) for both patients and controls, increased heart rate was significantly synchronized with increased negative affect, with patients showing overall stronger levels of synchrony between these two measures than controls; (b) for controls only, increased heart rate was significantly synchronized with increased positive affect; and (c) for patients only, increased skin conductance was significantly synchronized with both increased negative affect and decreased positive affect. These findings are discussed in relation to current conceptualizations of the construct of emotion as well as directions for future research and potential implications for clinical practice.
