Investigating the relationship between the five-factor model of distress tolerance, anxiety and anxiety sensitivity.

ABSTRACT

BACKGROUND: Distress tolerance (DT) has been conceptualized as a vulnerability factor for several psychopathologies. A five factor model of DT has been suggested, but its associations with anxiety and anxiety sensitivity have yet to be explored. OBJECTIVES: This study aimed to further validate the five-factor model of DT, identify the associations between its factors and elevated anxiety, and assess if anxiety sensitivity mediates the association between DT and anxiety. DESIGN AND METHODS: This observational study included 330 students and university workers (women = 82.7%; mean age = 27.7 years, SD = 9.4). They completed online questionnaires assessing DT, anxiety sensitivity and anxiety levels. RESULTS: The five-factor model was a good fit to the data (RMSEA = .04). Two factors, and the sex of the participants, contributed to the variance in anxiety (r2 = .418, p < .001). Tolerance of negative emotion was directly (ß = -1.98, 95% CI = [-2.53, -1.42]) and indirectly (ß = -1.10, 95% CI = [-1.55, -.78]) associated with lower anxiety through anxiety sensitivity. Tolerance of uncertainty was also directly (ß = -.08, 95% CI = [-.10, -.06]) and indirectly (ß = -.04, 95% CI = [-.05, -.02]) associated with lower anxiety through anxiety sensitivity. CONCLUSIONS: Tolerance of negative emotion and uncertainty were associated with anxiety independently of the other factors of DT. These associations seem partially explained by the effect of anxiety sensitivity.
