Factor analysis of the cognitive-somatic anxiety questionnaire

The Cognitive-Somatic Anxiety Questionnaire (CSAQ; Schwartz, Davidson, & Goleman, 1978) is a brief self-report rating scale designed to differentiate between cognitive and somatic symptoms of anxiety. The CSAQ gained relatively widespread acceptance as a behavioral assessment instrument before much was known about its psychometric properties. Psychometric studies of the CSAQ (e.g., DeGood & Tait, 1987) have raised questions about the instrument's item content and subscale structure. The primary purpose of the present study was to determine whether the Cognitive and Somatic subscales correspond to the instrument's factorial structure in a clinically anxious population. The sample consisted of 120 nonpsychotic psychiatric inpatients. Factor analysis with oblique rotation accounted for 60% of the total variance and yielded four factors that do not conform to the Cognitive-Somatic subscale structure. The results challenge the validity of the CSAQ and suggest the need for an improved instrument capable of differentiating the multidimensional features of clinical anxiety.
