Samdal et al. (2016) conduct the systematic review and meta-regression of 48 studies, focusing on behavior change techniques (BCTs) in the overweight and obese adult population. The authors consider the change in eating habits and healthy lifestyle as the key factors, leading to weight loss. The purpose of the article is to explore heterogeneity in the results of interventions, including BCTs and MI as well.
The findings of the study clearly show that short-term interventions significantly differ in their results, and long-term ones proved to be more similar in this respect. At this point, goal setting and self-monitoring are noted as the most effective interventions. The fidelity rates were reported only by few studies, yet the confidence interval was identified as 95 percent and 59.4 percent for long-term and short-term interventions, respectively.
The quality and level of evidence of the given article may be identified as level I because it uses the systematic review and meta-regression as the research methods. The findings of the study are relevant to the proposed research as they differentiate between short-term and long-term strategies on weight reduction among the obese population as specified in the PICOT question. Furthermore, these interventions are aimed at changing eating habits, and the results are provided compared to the traditional treatment.
In addition to goal setting and self-monitoring, person-centered and autonomy-supportive counseling are specified as effective measures to help obese people in reducing their weight. The application of this study is likely to promote credibility and compliance to the selected intervention in the perspective study. In particular, BCTs and MI will be used to evaluate the target audience and interpret the findings, thus contributing to the practice of change.
