This research will use existing data from the Relapse Replication and
Extension Project (RREP) to increase our understanding
of the relapse process in individuals who have received treatment for
an alcohol use disorder. This dataset includes pre- and post-treatment
assessment of drinking behavior, background characteristics, and relapse
precipitants in a group of 563 research participants, who were recruited
from 15 treatment sites that offered a variety of alcoholism treatment
approaches. Using a multi-deterministic framework, the relationship
between background variables, risk and protective factors, and situational
will be examined with respect to post-treatment drinking outcomes.
It is well-documented that a lack of effective coping responses increases
relapse risk; and self-efficacy, outcome expectancies, and the abstinence
violation effect, are cognitive factors that have been identified as
important mediators in the return to heavy drinking following treatment.
However, the relationship between these variables in the relapse process
has not been clearly established. Focusing on the process of relapse,
rather than evaluating relapse as a dichotomous event, the proposed
will examine trajectories of drinking behavior during the first year
after treatment for an alcohol use disorder. Specifically, the first
goal of the research is to further delineate the relationship between
coping behavior, background characteristics, and cognitive factors
in the prediction of these trajectories using advanced statistical models,
including both catastrophe models and general growth mixture models.
The second goal of the research is to test the utility and
of these advanced modeling techniques in the prediction of post-treatment
drinking outcomes. Gaining a better understanding of the relapse process
has been a primary goal of addictive behaviors research for the past
30 years. The abundance of treatment outcome data for addictive behaviors
makes the proposed research an important and cost-effective contribution
to the advancement of our understanding of the relapse process.
