Notes.Group differences were tested by generalized linear models with log link. Only diagnostic group contrast was entered in first models for each construct. Gender, age, group contrast, mean levels, and interaction of group and mean level were initially entered in the second models; gender and/or age were removed if non-significant. NA = negative affect; PA = positive affect; SAD = Social Anxiety Disorder Diagnosis (contrast coded); SSD = squared successive differences.
