Validation of the distress tolerance scale-short form in obsessive compulsive disorder.

OBJECTIVE: This study aimed to develop and validate the Distress Tolerance Scale-Short Form (DTS-SF), a modification of the original Distress Tolerance Scale, in a severe/complex sample of individuals with obsessive compulsive disorder (OCD). Currently, there are multiple self-report measurements of distress tolerance (DT), highlighting the need for a more refined measure.

METHOD: Participants included 222 individuals with a primary diagnosis of OCD (57% male, average age = 31) seeking intensive/residential treatment. Participants completed surveys at admission, discharge, and each week.

RESULTS: An exploratory factor analysis revealed a one-factor solution representing overall DT ability. The DTS-SF was found to be sensitive to treatment effects. Appropriate associations between the DTS-SF and other measures were also found, with lower DT associated with greater OCD and depression severity and lower reported quality of life.

CONCLUSION: The DTS-SF was found to be a valid and reliable measure with high clinical utility for quickly and accurately measuring DT.
