Integration of Motivational Interviewing and Self-Affirmation Theory into a Culturally Adapted Motivational Interview: A Case Study

Abstract

Annually, alcohol, tobacco, and illicit drug use are responsible for the 11.8 million deaths worldwide, exceeding the number of deaths from all cancers ( Ritchie & Roser, 2018 ). Motivational Interviewing (MI), a person-centered addiction counseling approach ( Miller & Rollnick, 2013 ), is designed for those with low motivation to change. MI is presumed to minimize client defensiveness by avoiding confrontation. Culturally adapting evidence-based treatments such as MI may reduce alcohol-related health disparities among Latinx adults. A completed randomized trial tested the relative efficacy of Culturally Adapted Motivational Interview (CAMI) compared to MI in Latinx drinkers. CAMI had beneficial alcohol use effects among persons who reported high discrimination and stigma ( Lee et al., 2019 ). Self-Affirmation Theory, which provides a mechanism where stigma effects can be buffered, was integrated into the CAMI. Augmenting affirmation in the CAMI is postulated to lower defensiveness and increase openness to information that pose a threat to self-image ( Sherman & Cohen, 2006 ). The purpose of this case example is to present the novel features of CAMI and to suggest how affirmation may have played in the CAMI’s beneficial effects for individuals with high discrimination. The case example illustrates how the CAMI addresses three conditions for self-affirmation associated with strongest effects on motivating behavior change ( Ferrer & Cohen, 2019 ): the presence of psychological threat, timing and availability of resources.
