Objective

To perform a systematic review and meta-analysis for the effects of physical activity intervention on self-esteem and self-concept in children and adolescents, and to identify moderator variables by meta-regression.

Design

A meta-analysis and meta-regression.

Method

Relevant studies were identified through a comprehensive search of electronic databases. Study inclusion criteria were: 1 intervention should be supervised physical activity, 2 reported sufficient data to estimate pooled effect sizes of physical activity intervention on self-esteem or self-concept, 3 participants’ ages ranged from 3 to 20 years, and 4 a control or comparison group was included. For each study, study design, intervention design and participant characteristics were extracted. R software version 3.1.3 and Stata version 12.0 were used to synthesize effect sizes and perform moderation analyses for determining moderators.

Results

Twenty-five randomized controlled trial RCT studies and 13 non-randomized controlled trial non-RCT studies including a total of 2991 cases were identified. Significant positive effects were found in RCTs for intervention of physical activity alone on general self outcomes Hedges’ g = 0.29, 95% confidence interval CI: 0.14 to 0.45; p = 0.001, self-concept Hedges’ g = 0.49, 95%CI: 0.10 to 0.88, p = 0.014 and self-worth Hedges’ g = 0.31, 95%CI: 0.13 to 0.49, p = 0.005. There was no significant effect of intervention of physical activity alone on any outcomes in non-RCTs, as well as in studies with intervention of physical activity combined with other strategies. Meta-regression analysis revealed that higher treatment effects were associated with setting of intervention in RCTs β = 0.31, 95%CI: 0.07 to 0.55, p = 0.013.

Conclusion

Intervention of physical activity alone is associated with increased self-concept and self-worth in children and adolescents. And there is a stronger association with school-based and gymnasium-based intervention compared with other settings.
