Predictive validity of the CognitiveVs. Somatic Anxiety Distinction

The purpose of this study was to test the predictive validity of an instrument, The Cognitive-Somatic Anxiety Questionnaire (CSAQ), which purports to measure separately cognitive and somatic anxiety. Twelve subjects with either predominantly cognitive or somatic anxiety received a treatment that matched their predominant anxiety mode (“matched”), and twelve received a treatment which addressed the secondary anxiety mode (“mismatched”). After five sessions, the “matched” subjects reported significantly fewer anxiety symptoms than the “mismatched” subjects. The results support the predictive validity of the CSAQ, and suggest that anxiety may not be a unidimensional phenomenon. The implications of these results for clinical practice are discussed.
