Refining the Measurement of Distress Intolerance

Distress intolerance is an important transdiagnostic variable that has long been implicated in the development and maintenance of psychological disorders. Self-report measurement strategies for distress intolerance (DI) have emerged from several different models of psychopathology and these measures have been applied inconsistently in the literature in the absence of a clear gold standard. The absence of a consistent assessment strategy has limited the ability to compare across studies and samples, thus hampering the advancement of this research agenda. This study evaluated the latent factor structure of existing measures of DI to examine the degree to which they are capturing the same construct. Results of confirmatory factor analysis in three samples totaling 400 participants provided support for a single-factor latent structure. Individual items of these four scales were then correlated with this factor to identify those that best capture the core construct. Results provided consistent support for 10 items that demonstrated the strongest concordance with this factor. The use of these 10 items as a unifying measure in the study of DI and future directions for the evaluation of its utility are discussed.

► Distress intolerance is an important transdiagnostic vulnerability factor. ► Measurement of distress intolerance is hampered by inconsistency across studies. ► Measures of distress intolerance appear to load onto 1 latent factor. ► Use of 10 items drawn from existing measures may provide an alternative to use of multiple measures.
