A list of negative outcomes (harmful events) was constructed to invest
igate the nature and organization of outcome concerns in anxiety. In S
tudy 1, analysis of worry frequency ratings for the 116 negative outco
mes revealed two major correlated factors corresponding to physical ou
tcomes (harm or misfortune) and social outcomes (negative evaluation).
These higher-order factors could be further subdivided into smaller d
iscrete categories of related concerns. Ratings of worry frequency wer
e higher for social outcomes. Trait anxiety was associated with both p
hysical and social concerns, but stress and depression were primarily
associated with social concerns. In Study 2, aversiveness ratings for
the 116 negative outcomes followed the same physical-social organizati
on and formed similar lower-order categories. Unlike the worry frequen
cy ratings, aversiveness ratings were higher for physical than social
categories, and did not correlate substantially with trait measures of
depression, anxiety or stress. In Study 3, a short (24-item) negative
outcome questionnaire was developed to discriminate between concerns
about physical and social outcomes. The Physical Scale correlated subs
tantially with the Anxiety Sensitivity Index (ASI) but not the Fear of
Negative Evaluation (FNE), whereas the Social Scale correlated with t
he FNE but not the ASI. The Penn State Worry Questionnaire (PSWQ), whi
ch assesses worry frequency but not content, correlated only with the
Social Scale. Implications for theories of normal and clinical anxiety
are discussed.
