Optimizing the length and reliability of measures of mechanisms of change to support measurement-based care in alcohol use disorder treatment.

OBJECTIVE: Clients who receive alcohol use disorder (AUD) treatment experience variable outcomes. Measuring clinical progress during treatment using standardized measures (i.e., measurement-based care) can help indicate whether clinical improvements are occurring. Measures of mechanisms of behavioral change (MOBCs) may be particularly well-suited for measurement-based care; however, measuring MOBCs would be more feasible and informative if measures were briefer and if their ability to detect reliable change with individual clients was better articulated. METHOD: Three abbreviated measures of hypothesized MOBCs (abstinence self-efficacy, coping strategies, anxiety) and a fourth full-length measure (depression) were administered weekly during a 12-week randomized trial of cognitive-behavioral therapy (CBT) for women with AUD. Psychometric analyses estimated how reliably each measure distinguished within-person change from between-person differences and measurement error. Reliability coefficients were estimated for simulated briefer versions of each instrument (i.e., instruments with fewer items than the already-abbreviated instruments) and rates of reliable improvement and reliable worsening were estimated for each measure. RESULTS: All four measures had good reliability (.86-.90) for detecting within-person change. Many participants (41.4%-62.5%) reliably improved on MOBCs from first to last treatment session. Reliable improvement on MOBCs was associated with reductions in percentage of drinking days (PDD) at 3, 9, and 15-month follow-ups. Simulated briefer versions of each instrument retained good reliability for detecting change with only 3 (self-efficacy), 11 (coping strategies), 5 (anxiety), or 10 items (depression). CONCLUSIONS: Brief MOBC measures can detect reliable change for individuals in AUD treatment. Routinely measuring MOBCs may help with monitoring clinical progress.

Menstrual cycle phase, alcohol consumption, alcohol cravings, and mood among women in outpatient treatment for alcohol use disorder.

Research shows fluctuations in drinking across the menstrual cycle among women with alcohol use disorder (AUD), but little work has investigated moderators of these fluctuations. This study examined drinking and craving intensity across the menstrual cycle, and the moderating effect of baseline depression and emotional distress during the midlate luteal phase and/or menses, among women receiving AUD treatment. Fifty-nine regularly cycling women reported menstrual history and baseline depression. Over 3 months of treatment, they kept daily logs of drinks, alcohol cravings, and menstruation (yes/no). Emotional distress during the midlate luteal phase and/or menses of their most recent menstrual cycle was also assessed during treatment. Menstrual cycle phase was estimated for each within-treatment day. Mixed model analyses tested main and interactive effects of menstrual cycle phase, baseline depression, and emotional distress during the midlate luteal phase and/or menses on daily drinks and craving intensity. Women drank most during the midlate luteal phase and menses compared with other phases. Among women with lower baseline depression, those with lower distress during the midlate luteal phase and/or menses reported more intense cravings during the midlate luteal phase (ΔM = .77, p = .000) and menses (ΔM = .51, p = .012); those with higher distress reported more intense cravings during menses, compared with all other phases (p < .01). Among women with higher baseline depression, craving intensity remained consistently high. Results document more drinking during the midlate luteal phase and menses and suggest that cycle-related distress and depression moderate the alcohol-menstrual association among women in AUD treatment.
