Am. Shapiro et al., Differentiating symptoms of anxiety and depression in older adults: Distinct cognitive and affective profiles?, COGN THER R, 23(1), 1999, pp. 53-74
Cognitive and affective dimensions of symptoms of anxiety and depression we
re examined in a sample of 283 community-dwelling older adults (ranging in
age from 65 to 93 years). A principal-axis factor analysis with varimax rot
ation conducted on the Cognition Checklist (CCL) revealed a factor structur
e different than that found in younger adults. Three factors emerged (Anxio
us, Social Loss, and Negative Self-Evaluation/Worthlessness Cognitions) and
, in general, these cognitions were not specifically related to anxious and
depressive symptoms. Instead, worthlessness cognitions were robustly assoc
iated with both anxious and depressive symptoms including variance that was
unique to each. In terms of affective dimensions, factor analyses revealed
that only anxiety-related items loaded on the negative affectivity subscal
e. Consequently, negative affectivity was strongly related to variance that
was unique to anxious symptoms, but was only weakly related to variance th
at was unique to depressive symptoms. On the other hand, positive affectivi
ty was only weakly associated with both forms of symptomatology. Findings a
re discussed in terms of the cognitive and affective distinctions between o
lder and younger adulthood.
