The Motivational Interviewing Treatment Integrity Code has been revised to address new evidence-based elements of motivational interviewing (MI). This new version (MITI 4) includes new global ratings to assess clinician’s attention to client language, increased rigor in assessing autonomy support and client choice, and items to evaluate the use of persuasion when giving information and advice. Method: Four undergraduate, non-professional raters were trained in the MITI and used it to review 50 audiotapes of clinicians conducting MI in actual treatments sessions. Both kappa and intraclass correlation indices were calculated for all coders, for the best rater pair and for a 20% randomly selected sample from the best rater pair. Results: Reliability across raters, with the exception of Emphasize Autonomy and % Complex Reflections, were in the good to excellent range. Reliability estimates decrease when smaller samples are used and when fewer raters contribute. Conclusion: The advantages and drawbacks of this revision are discussed including implications for research and clinical applications. The MITI 4.0 represents a reliable method for assessing the integrity of MI including both the technical and relational components of the method.
This study tests the feasibility, safety, and short-term preliminary effects of a relapse prevention and relationship safety (RPRS) intervention in reducing drug use and the experience of intimate partner violence (IPV) among women on methadone. For this randomized controlled trial, 34 women who met IPV and drug use criteria were randomly assigned to either the RPRS condition (n = 16) or a one-session informational control (IC) condition (n = 18). RPRS participants were more likely than IC participants to report a decrease in minor physical or sexual IPV (OR = 7.1, p = .05), minor psychological IPV (OR = 5.3, p = .03) and severe psychological IPV (OR = 6.07, p = .03) at the 3-month follow-up. Data suggest that RPRS participants were also more likely than IC participants to report a decrease in any drug use at 3 months (OR = 3.3, p = .08). This study provides preliminary evidence that the RPRS intervention is effective in reducing IPV and drug use among women on methadone.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
