Abstract
Background: Relapse may occur suddenly, following a short period of craving, or after extended consideration. The time to relapse may reveal underlying mechanisms of relapse and have important implications for treatment. Objective: The Time to Relapse Questionnaire (TRQ), a self-administered questionnaire, was designed to assess the time from the initial thought of drug use to actual use. Methods: Psychometric properties of the TRQ were evaluated in two distinct populations (n = 183 and 194) with DSM-IV primary substance use disorders. Results: Factor analysis and item refinement led to a 9-item TRQ with a three-factor solution accounting for 63% of the total variance. Three discrete types of relapse style were identified: Sudden Relapse, Short Delay Relapse, and Long Delay Relapse. The TRQ demonstrated good construct validity and adequate internal consistency for the total (α = .61) and individual factor (α = .64-.75) scores. Measures to assess convergent validity of the TRQ suggest that Sudden Relapse may not reflect more generalized deficits of inhibitory control. Conclusions and Significance: The TRQ may provide a useful self-report measure to discriminate between addicted patients who relapse without forewarning compared to those with a period of delay. Clinical interventions may be targeted towards different relapse styles.
