Perhaps, in the present sample the description of the items in the
social concerns subscale include either physical concerns or mental incapacitation
or both. The overlap of items could result in social concerns contributing little to
no unique variance in predicting the anxious and depressive symptoms yielding
social concerns to not be a significant predictor of any of the anxiety or
depressive symptoms. The mental incapacitation subscale together with physical
concerns subscale may cover the construct of fear of publically observable
symptoms. Perhaps mental incapacitation may be the more prominent underlying
belief associated with symptoms of social anxiety rather than social concerns in
both men and women. Additionally in men, both mental incapacitation and
physical concerns may be beliefs underlying social anxiety symptoms
