Psychometric properties, validity, and reliability of the Temporal Experience of Pleasure Scale state version in an opioid-dependent sample.
Individuals with substance dependence commonly experience anhedonia. Theories of anhedonia distinguish between anticipatory and consummatory reward deficits, with the Temporal Experience of Pleasure Scale (TEPS) the first self-report scale to separately measure these two constructs. Several psychometric studies have analysed the trait version of the TEPS, but the state version of the TEPS has not been previously validated. ⋯ In opioid-dependent participants, the TEPS state version appeared to have good validity as a measure of state anhedonia. However, evidence for its ability to distinguish between consummatory and anticipatory anhedonia was weak.
