Stages of change and self-efficacy for controlling drinking and driving: a psychometric analysis.
Indicators of self-efficacy and motivation to change (stage of change) with regard to drinking and to drinking and driving were examined in a sample of Driving Under the Influence (DUI) offenders in a court-mandated intervention program. Self-administered questionnaires that contained pertinent measures were completed by 210 consenting offenders (34 of whom were female) during the intervention program. A factor analysis of efficacy and stages of change items showed distinct factors for the respective constructs; however, drinking and drinking-and-driving items of the same type (e.g., efficacy or stages of change) tended to codefine common factors, and the factor pattern suggested that motivations and efficacy for changing drinking behavior are critical for avoiding the drinking-and-driving sequence. Most participants were classified into the action stage in both drinking and drinking-and-driving domains. In regression analysis, contemplation of action and self-efficacy measures pertaining to drinking and driving predicted prior crashes and arrests; however, after accounting for recent alcohol problems, action items pertaining to drinking and driving were the best predictors of recent drinking-and-driving incidents.
