Abstract

OBJECTIVE:

Few studies have examined the effects of brief motivational intervention components, such as change-plan completion, on treatment outcomes. This secondary analysis of an opportunistically recruited emergency-department sample of hazardous injured drinkers examines the potential predictive role of an alcohol-related change plan on treatment outcomes after accounting for pretreatment readiness. Written change plans were independently rated.

METHOD:

A mediational analysis framework tested directional hypotheses between pretreatment readiness, change plan, and treatment outcomes using linear regressions. The baseline total Drinker Inventory of Consequences (DrInC) score was covaried on 12-month DrInC total score, in all analyses. Participants who completed a brief motivational intervention and a change plan were included (N = 333).

RESULTS:

Pretreatment readiness was negatively associated with alcohol consequences at 12 months, (beta = -.09, t(254) = -2.07, p < .05, and good-quality change plans, (beta = .18, t(320) = 4.37, p < .001. With change plan and readiness in the same model, the relationship between readiness and treatment outcomes became nonsignificant, but change plan remained a significant predictor of treatment outcomes in the expected direction, beta = -.17, t(254) = -2.89, p < .01. Follow-up generalized linear modeling including an interaction term (change plan and pretreatment readiness) revealed that those with high readiness and a good-quality change plan versus those with low readiness and a poor-quality change plan had better-than-predicted outcomes for either readiness or change plan alone.

CONCLUSIONS:

Study findings suggest that the change plan in brief motivational intervention may be an active ingredient of treatment associated with better outcomes over and above the influence of pretreatment readiness.
