Description:Objective:
Using data from Project CHOICES, a randomized controlled trial to test an intervention to prevent alcohol-exposed pregnancies, this study examined process of change profiles composed of Transtheoretical Model of Change (TTM) constructs for alcohol. The primary purpose was to identify a profile of TTM variables associated with reduced drinking.
Method:
Participants (n=570) were women at risk of an alcohol-exposed pregnancy recruited from high risk settings. Profile analyses compared end-of-treatment (i.e. 3 months post-intake) TTM construct mean profiles for women who reduced drinking to below NIAAA-defined risk levels1 (changers) to women who continued to drink at risk levels (non-changers) at the 9-month follow-up. TTM construct profiles included experiential and behavioral processes of change, pros and cons for change, confidence to reduce drinking, and temptation to drink above risk levels.
Results:
Results revealed a parallelism effect or interaction (p<.001) in the end-oftreatment TTM construct profiles for the changers versus the non-changers at the 9-month follow-up. Changers reported greater pros (p<.001) and lower cons for change (p=.012), greater confidence (p=.030), lower temptation (p<.001) and greater use of the experiential (p<.001) and behavioral processes of change (p<.001). A larger percentage of the women from the CHOICES intervention were in the end-of-treatment profile of the changers (48%) compared to the control condition (39%; p=.042).
Conclusions:
Interventions can potentially be enhanced by clinicians’ understanding what successful change ‘looks like’ for specific clients in terms of their process use, decisional balance and self-efficacy, allowing for tailored interventions targeted to each client’s specific strengths and deficits.
