Interaction of Motivation and Social Support on Abstinence among Recovery Home Residents.

The impetus to abstain from alcohol and drugs is especially robust when individuals seek help. However, motivation to continue abstinence during ongoing recovery is less understood. The present study assessed how social support interacted with motivation to affect abstinence over an 18-month time period. A sample of 289 residents entering residential recovery homes was recruited and followed at 6-, 12-, and 18-months. Motivation was measured as the perceived costs and benefits of abstinence. Five social influence measures were used to assess interactive effects with costs and benefits on abstinence. Perceived costs and benefits of abstinence were robust predictors of abstinence over the 18-month assessment period. Two social support factors interacted with perceived benefits to influence abstinence: 12-step involvement and number of persons in the social network. Suggestions are made for recovery services to influence perceived costs, benefits, and social network characteristics.
