Examining the Psychometric Properties of the Reward and Relief Inventory of Drinking Situations
Recent work has examined the extent to which individuals seek alcohol to enhance positive experiences (reward drinking) or relieve aversive states (relief drinking), and processes underlying reward/relief drinking correspond to neurobiological adaptations within the addiction cycle. Previous findings indicate the utility of reward/relief drinking phenotypes in matching patients to AUD pharmacotherapies, with high reward drinkers responding better to naltrexone versus placebo. Practical reward/relief drinking measures with good psychometric properties are needed to translate these findings to clinical practice. We examined the reliability and construct validity of a recently developed brief measure of reward /relief drinking, the Reward and Relief Inventory of Drinking Situations (RR-IDS). Sixty-five individuals (51% female; 77% White, 8% multiracial, 6% American Indian, 9% other racial identities; 49% Hispanic; mean age=31.6 years) with high-risk alcohol use based on the AUD Identification Test were recruited in New Mexico. The RR-IDS reward (α=.866-.897) and relief (α=.905-.917) subscales demonstrated good internal consistency and test-retest reliability over one month (reward intraclass correlation coefficient (ICC)=.652; relief ICC=.722). The RR-IDS reward subscale was associated with greater social and enhancement motives, reward responsiveness, and sensation seeking (ps<0.05). Conversely, the relief subscale was associated with greater age, AUD severity, alcohol craving, coping motives, negative urgency, and depression and anxiety, and lower age of alcohol initiation and positive affect (ps<0.05). Pending additional information on the RR-IDS' predictive validity and clinical utility, implementing this measure in clinical settings might help match patients to AUD treatments that work best for them.
