The Sweating Cognitions Inventory: A Measure of Cognitions in Hyperhidrosis

Primary hyperhidrosis is a dermatological condition involving excessive sweating. Little research has been conducted on the psychological processes associated with this condition. A cognitive-behavioral approach would suggest that negative beliefs about the nature and consequences of sweating paradoxically increase sweating, and therefore maintain hyperhidrosis. The present research reports on the development and psychometric evaluation of the Sweating Cognitions Inventory (SCI), a self-report measure that assesses dysfunctional beliefs in hyperhidrosis. The SCI was administered to a clinical sample of patients diagnosed with hyperhidrosis (N = 226) as well as a student comparison group (N = 482). The SCI demonstrated good internal consistency and a stable, unidimensional factor structure in both samples. Sweating cognitions differentiated between the two groups, indicating discriminant validity. Correlations with comparison measures indicated that sweating cognitions were strongly related to sweating severity, and also to social anxiety and anxiety sensitivity. These results are consistent with our conceptualization that dysfunctional sweating cognitions can maintain and exacerbate excessive sweating. A cognitive-behavioral conceptualization of hyperhidrosis could advance our understanding of the condition and could lead to novel treatment approaches.
