Title: "Commitment, Confidence, and Processes of Change as Mechanisms in Modifying Drinking Behavior." Paper presented at the Research Society on Alcoholism (RSA) annual meeting, San Diego, CA, June 2009.

Abstract: Changing drinking behavior requires individuals to exercise self-regulatory mechanisms that require effort, a variety of coping mechanisms, and a sense of personal efficacy. This presentation will share initial results from an R21 NIAAA MOBC trial that examines modification of drinking behavior over an initial 12 week period of treatment and its relationship with changes in commitment, efficacy (confidence to abstain) and experiential and behavioral coping activities among alcohol abusing and dependent clients. These personal process variables are assumed to operate as mechanisms of change and shift prior to or immediately following changes in drinking. Extensive assessments at baseline, six weeks, and 12 weeks along with twice a week telephone assessments by Interactive Voice Technology are providing data on variables of interest on a weekly basis. Participants are individuals entering treatment in several community treatment agencies whose primary drug of abuse is alcohol and who have been drinking in the past month, are English speaking, without any cognitive impairment. Parallel process linear modeling statistical methods will be used to evaluate the relationships among these potential mechanism variables and drinking behaviors. Secondary data analysis of Project MATCH client session reports which was included in this project have demonstrated significant co-variation between patterns of drinking and both abstinence efficacy and processes of change. This study provides the microanalysis of process activity and drinking needed to better understand personal mechanisms of drinking behavior change.
