SECONDARY outcome
Timeframe: baseline, 2, 4, and 6 monthsDrinkers' and partners' psychological distress was assessed by the OQ-45 scale. Response options range from 0-4, with items 1, 12, 13, 20, 21, 24, 31, 37, and 43 reversed; items are summed (i.e., a possible range of 0-180). High scores suggest distress (anxiety, depression, somatic problems, stress), difficulties in interpersonal relationships and social roles (e.g., work), and low quality of life, with scores of 63 or more indicating symptoms of clinical significance, and changes of 14 points or more considered reliable.
