Is fidelity to motivational interviewing associated with alcohol outcomes in treatment-seeking 60+ year-old citizens?

Preliminary evaluation of a novel group-based motivational interviewing intervention with adolescents: a feasibility study

Drinking is closely intertwined with social life among many adolescents, particularly in Europe. Group-based interventions, such as group-based motivational interviewing (group MI), have shown the capacity to prevent and reduce hazardous drinking and related problems among adolescents, but few examinations have been conducted in a European high school setting. This study examines the preliminary outcomes of a pilot group MI intervention among Danish adolescents. High school students (ages 15-18 years) were randomly allocated to two 1-h group MI sessions delivered in a school setting (N = 65) or an assessment only control condition (N = 67). Data were collected in August and November 2020 using online self-administrated questionnaires regarding the acceptability of the intervention and past month alcohol use. The pilot group MI intervention showed high feasibility and acceptability in this setting and with this age group. Group MI adolescents significantly reduced peak drinks per drinking day compared to assessment only adolescents (-2.7 drinks, p < 0.05). Results are discussed in relation to the metrics being evaluated during COVID-19 lockdown, including increased social restrictions at follow-up compared to baseline. Group MI shows promise for reducing hazardous alcohol use among Danish adolescents. In addition, the findings indicate the importance of building on and extending this work in future larger, better-powered randomized controlled trials.

Adapted motivational interviewing for brief healthcare consultations: A systematic review and meta-analysis of treatment fidelity in real-world evaluations of behaviour change counselling

BACKGROUND

Behaviour change counselling (BCC) is an adaptation of motivational interviewing (MI) designed to maximize the effectiveness of time-limited health behaviour change consultations. To improve intervention quality and understanding of treatment effects, it is recommended that evaluations of health behaviour change interventions incorporate existing fidelity frameworks (e.g. The National Institutes of Health [NIH] Behaviour Change Consortium) and ensure that treatment fidelity is assessed and reported.

PURPOSE

This systematic review was designed to examine (a) adherence to NIH fidelity recommendations, (b) provider fidelity to BCC and (c) impact of these variables on the real-world effectiveness of BCC for adult health behaviours and outcomes.

METHODS AND RESULTS

Searches of 10 electronic databases yielded 110 eligible publications describing 58 unique studies examining BCC delivered within real-world healthcare settings by existing providers. Mean study adherence to NIH fidelity recommendations was 63.31% (Range 26.83%-96.23%). Pooled effect size (Hedges g) for short-term and long-term outcomes was .19 (95% CI [.11, .27]) and .09 (95% CI [.04, .13]), respectively. In separate, random-effects meta-regressions, neither short-term nor long-term effect sizes were significantly modified by adherence to NIH fidelity recommendations. For the subgroup of short-term alcohol studies (n = 10), a significant inverse relationship was detected (Coefficient = -.0114, 95% CI [-.0187, -.0041], p = .0021). Inadequate and inconsistent reporting within the included studies precluded planned meta-regression between provider fidelity and BCC effect size.

CONCLUSIONS

Further evidence is needed to clarify whether adherence to fidelity recommendations modifies intervention effects. Efforts to promote transparent consideration, evaluation and reporting of fidelity are urgently needed. Research and clinical implications are discussed.

Improvement in quality of life among women and men aged 60 years and older following treatment for alcohol use disorder

BACKGROUND

Previous studies have yielded mixed results on the association between gender and alcohol use disorder (AUD) treatment outcomes. Thus, additional research is needed to determine the effect of gender on AUD treatment outcomes, including quality of life (QoL), particularly among older adults.

AIMS

In a clinical sample of older adults with DSM-5 AUD, we examined changes in QoL from the beginning of AUD treatment through 1 year of follow-ups. We also examined the effect of gender and explored interaction effects with gender on QoL.

METHODS

We utilized data from the "Elderly Study," a multi-national, single-blind, randomized, controlled trial of 693 adults aged 60+ with DSM-5 AUD. Alcohol use was assessed with the Form-90, and QoL with the brief version of the World Health Organization QoL measure. Information was collected at treatment initiation and at 4-, 12-, 26-, and 52-week follow-ups. Multilevel mixed-effects logistic and linear regression models were used to examine QoL changes and the effect of gender on changes in QoL.

RESULTS

Following treatment, small, but significant improvements were seen over time in overall perceived health (p < 0.05). Improvements that persisted over the 1-year follow-up period were seen in the QoL domains of physical health (β: 2.6, 95% CI: 1.4-3.9), psychological health (β: 3.5, 95% CI: 3.3-3.8), social relationships (β: 4.0, 95% CI: 2.5-5.6), and environmental health (β: 1.4, 95% CI: 0.4-2.4). No significant changes were seen over time in overall perceived QoL (p = 0.58). Gender was not associated with changes in any of the QoL outcome measures (all p ≥ 0.05).

CONCLUSIONS

Among 60+ year-old adults receiving treatment for DSM-5 AUD, improvements in QoL were achievable and maintained over time, but were not associated with gender.

Preliminary Support for the Use of Motivational Interviewing to Improve Parent/Adult Caregiver Behavior for Obesity and Cancer Prevention

Motivational interviewing (MI) is a promising behavioral intervention for improving parent and adult caregiver (PAC) health behavior for obesity and cancer prevention. This study explored the preliminary effects of MI from a registered dietitian (RDMI) within an obesity prevention intervention to promote PAC behavior change and positive proxy effects on children and the home environment. N = 36 PAC/child dyads from low-resource communities were enrolled in a randomized trial testing a 10-week obesity prevention intervention. Intervention dyads were offered RDMI sessions. Data were collected at baseline and post-intervention (PAC diet quality (Healthy Eating Index (HEI)), child skin carotenoids, home environment, and PAC ambivalence regarding improving diet). Results show that for every RDMI dose, PAC HEI scores increased (0.571 points, p = 0.530), child skin carotenoid scores improved (1.315%, p = 0.592), and the home food environment improved (3.559%, p = 0.026). There was a significant positive relationship between RDMI dose and change in ambivalence (ρ = 0.533, p = 0.007). Higher baseline ambivalence was associated with greater dose (ρ = -0.287, p = 0.173). Thus, RDMI for PACs may improve diets among PACs who are otherwise ambivalent, with potential effects on the diets of their children and the home food environment. Such intervention strategies have the potential for greater effect, strengthening behavioral interventions targeting obesity and cancer.

Differences in the delivery of motivational interviewing across three countries

We do not know if the delivery of Motivational Interviewing (MI) differs across countries. In an international study targeting Elderly people with Alcohol Use Disorder, The Elderly Study, MI was part of the treatment applied. Treatment delivery was measured by means of the Motivational Interviewing Treatment Integrity code version 4 (MITI 4). Mixed effects models explored potential differences in delivery of MI between the countries. Delivery of MI differed significantly between participating countries: Denmark, Germany and the US. These findings are important to consider when comparing measures of MI integrity across studies from different cultures.

Impact of motivational interviewing on early childhood caries: A systematic review and meta-analysis

BACKGROUND

The authors aimed to assess the scientific evidence on motivational interviewing for the clinical reduction of early childhood caries compared with traditional dental health education.

METHODS

Search terms were selected on the basis of Medical Subject Headings and non-Medical Subject Headings terms. The main key words were motivational interviewing, early childhood caries, and education. Potentially eligible studies involved the clinical assessment of caries rate in children whose parents or caregivers received motivational interviewing as an intervention. The authors assessed the risk of bias using the Cochrane risk-of-bias tool. In March 2019, the authors performed an electronic database search of literature published in English within the following databases: Scopus, Cochrane, PubMed, and Embase.

RESULTS

Of 329 articles retrieved initially, 14 were eligible for inclusion in the systematic review and 3 articles contributed to the meta-analysis. For statistical analysis, the mean difference of continuous data was analyzed at a 95% confidence interval using the random-effects model.

CONCLUSIONS

Overall, the evidence presented in this review was limited. Although the results of the meta-analysis showed that motivational interviewing is as effective as dental health education in controlling early childhood caries, we need more and better designed and reported interventions to assess its impact on early childhood caries accurately.
