Measurement Invariance of the Readiness to Change Questionnaire Among Injured Patients Who Received a Brief Intervention for Alcohol Use

The Relationship between Mindfulness and Readiness to Change in Alcohol Drinkers

Mindfulness is a multi-faceted construct that involves paying attention to thoughts and emotions without automatically reacting and being critical of them. Recent research has suggested that mindfulness might play an important role in reducing problematic alcohol use. Further, Readiness to Change (RTC) is related to motivation to change drinking behaviours. The RTC scale identifies motivation to change drinking behaviours including Precontemplation, Contemplation, and Action stages. The current study investigated, for the first time, the relationship between mindfulness (and its facets) and RTC in relation to drinking behaviours. Undergraduate students from Western Sydney University (N = 279) were screened for drinking levels using the Alcohol Use Disorder Identification Test (AUDIT) and then completed the Readiness to Change Questionnaire (RCT) and the Five Facets Mindfulness Questionnaire (FFMQ), which includes the following facets: Acting with Awareness, Non-Judging of Inner Experience, Non-Reactivity to Inner Experience, Describing, and Observing. Results show that overall, mindfulness and its facets negatively correlated with RTC. Multiple regression analysis further showed that Awareness and Non-Judgement facets negatively predicted RTC. These findings provide insight into how the facets of mindfulness interact with the drinking motives of individuals and their intentions to change drinking behaviours. Based on these findings, we recommend the incorporation of mindfulness techniques in interventions targeting problematic drinking.

Drinking motives as a predictor of readiness to change alcohol use

Drinking motives have been identified as important predictors of alcohol consumption. Similarly, the degree of readiness to change (RTC) can predict behavioral changes when drinking alcohol. However, the link between drinking motives and RTC has not been explored in previous research. The aim of this study is to investigate whether the four drinking motives (coping, enhancement, social, conformity) can predict the three stages of RTC (precontemplation, contemplation and action) in relation to alcohol consumption. Two hundred and fifty-two undergraduates’ students completed an online self-assessment survey on Qualtrics that assessed motives for alcohol use, drinking behavior, and RTC. Hierarchical regressions showed that among the four specific drinking motives, coping motives significantly predicted all three stages of RTC; conformity motives positively predicted the action stage of change; social motives negatively predicted the precontemplation and action stages of change; enhancement motives were not significant in predicting RTC stages. These results indicate that the three RTC levels can be predicted by coping, social, and conformity motives, but not by enhancement motives. Additionally, given the importance of coping motives, it might be useful to address and include healthier coping mechanisms as part of clinical interventions and prevention methods to circumvent unsafe drinking behaviors independent of a single RTC stage.

Measurement invariance of the University of Rhode Island Change Assessment Scale in Project MATCH: An exploratory structural equation modeling approach

BACKGROUND

Progression through the stages of change is a proposed mechanism underlying the effects of treatment for alcohol use disorder (AUD). However, examining stages of change as a mechanism of treatment effects requires that the measure be invariant across patient subgroups, treatment conditions, and time. In this study, we examined measurement invariance of the University of Rhode Island Change Assessment Scale (URICA) in Project MATCH using an exploratory structural equation modeling (ESEM) approach.

METHODS

We conducted a secondary analysis of data from Project MATCH (N = 1726; M_age  = 40.2, SD = 10.9; 75.7% male; 80% non-Hispanic white), a multisite randomized clinical trial that tested three AUD treatments: Motivational Enhancement Therapy, Cognitive-Behavioral Therapy, or Twelve-Step Facilitation. Participants completed the 24-item URICA for assessing the stages of change in relation to drinking at baseline and post-treatment (3 months after baseline).

RESULTS

A 4-factor ESEM provided a good fit to the data and a better fit to the data than a conventional 4-factor confirmatory factor analysis model. Further, the URICA demonstrated scalar invariance across each patient subgroup at baseline (sex, ethnicity, marital status, education, and parental history of AUD) and treatment condition at follow-up. However, the URICA was not longitudinally invariant as the metric model resulted in a significant decrement in model fit.

CONCLUSIONS

Measurement invariance of the URICA over time was not supported. Longitudinally invariant measures of the stages of change are needed to test the proposal that progression through the stages explains treatment effects.
