Factor Structure and Incremental Utility of the Distress Tolerance Scale: A Bifactor Analysis.

Abstract

The Distress Tolerance Scale (DTS) is a self-report measure of perceived capacity to withstand aversive emotions. Initial factor analysis of this measure suggested a structure comprising one higher-order factor and four lower-order domain-specific factors. However, there is limited evidence in support of the DTS's purported multidimensionality, and despite use of the DTS subscales, research has yet to assess their incremental utility. The current investigation sought to rectify the paucity of evidence in support of the DTS's factor structure and independent use of DTS subscales via bifactor analysis. In the present study (N = 826 community adults), a bifactor model of the DTS provided the best fit to the data. However, an examination of statistical indices associated with bifactor modeling, as well as results from an examination of incremental utility, suggest that the domain-specific factors are largely redundant with the general factor and do not provide incremental utility in predicting relevant clinical constructs beyond the general factor. Measurement invariance between sexes was confirmed. Taken together, results support use of a DTS total score, but not subscale scores.
