Does Motivational Interviewing Improve the Weight Management Process in Adolescents? A Systematic Review and Meta-analysis

Motivational Interviewing in Pediatric Obesity: A Meta-analysis of the Effects on Behavioral Outcomes

“…This indicates that MI outperforms the alternative (usual care) for a period (3–6 months) immediately after the interventions. The small effect on ↓sugary beverages noted in this meta-analysis (−0.16) is relatively lower to a recent meta-analysis focusing on adolescents weight management process (SMD = −0.47, k = 3, I 2 = 26.2%) [ 66 ]. The effect of MI on children’s MVPA (0.22, p < .05) is significantly better than a recent meta-analysis assessing the effect of MI delivered in primary care settings with adults during a period of 6 months (0.04, 95% CI = −0.06 to 0.14) [ 67 ].…”

Motivational interviewing—an evidence-based, collaborative, goal-oriented communication approach in lifestyle medicine: A comprehensive review of the literature

“… 16 In another recent systematic review of adolescents (n = 19 studies), the MI intervention group showed a reduction in sugary beverage intake (standardized mean difference [SMD] = −0.47; K = 3; I 2 = 26.2%) and waist circumference (SMD = −0.51; 95% confidence interval [CI] = −0.91, −0.11). 17 In a meta-analysis (n = 10 studies) by Suire et al., MI interventions have been found to support weight management among women by producing significant changes in anthropometric outcomes. The effect sizes of MI in reducing body weight and body mass index were 0.19 (95% CI = −0.13, 0.26; p < 0.01) and 0.35 (95% CI = 0.12, 0.58; p < 0.01), respectively.…”
