University of Missouri--Kansas City, 2015Although studies have demonstrated that change talk (CT) and sustain talk (ST) are
related to behavior change in multiple addictive behaviors, few have investigated the
relationship between change talk and outcome in health promotion. This is the first study to
investigate whether CT and ST are related to HIV medication adherence in a sample of
individuals recruited to participate in an ART adherence intervention. MI session tapes from
92 HIV-positive patients were coded for frequency of utterances expressing desire, ability,
reasons, need, commitment, other, and taking steps to adhere/not adhere to an ART
medication regimen. Strength of language as well as summary scores for both frequency and
strength ratings were calculated. Adherence was assessed at Week 2 and Week 12. There was
a significant relationship between Total ST and adherence at Week 2. Additionally, multiple
regression with bootstrapped standard errors showed that Taking Steps ST was negatively
related to adherence at both Week 2 and Week 12. Finally, Taking Steps Strength was related
to adherence at Week 2 only. Findings from this study support the need for coding for
individual change talk categories to determine what individual forms of change talk are
related to health behaviors. The identification of Taking Steps ST as a predictor of poorer
adherence suggests that Taking Steps ST might be an indicator of barriers to adhere to ART
regimens.Introduction -- Review of literature -- Methodology -- Analyses -- Results -- Discussion --Appendix A. Summary of review of literature for Change Talk studies -- Appendix B. Manual for the Motivational Interviewing Skill Code v 2.
