Summary
Perfectionism interventions effectively reduce disordered eating and perfectionism, with moderate effects on anxiety and depression. These findings suggest potential benefits for eating disorder treatments.
Area of Science:
- Psychology
- Clinical Psychology
- Mental Health
Background:
- Perfectionism is a significant risk factor for depression, anxiety, and eating disorders.
- Perfectionism interventions have demonstrated efficacy in addressing these mental health concerns.
Purpose of the Study:
- To systematically review and meta-analyze studies on perfectionism interventions.
- To assess the impact of these interventions on perfectionism, disordered eating, body image concerns, depression, and anxiety.
Main Methods:
- Systematic review of Medline, PsycINFO, and Scopus databases.
- Meta-analysis using between- and within-group effect size calculations.
- Inclusion of eight studies for between-group and nine for within-group analyses.
Main Results:
- Perfectionism interventions showed large effect sizes in reducing perfectionism and disordered eating.
- Moderate effect sizes were observed for reductions in depression and anxiety.
- Significant heterogeneity was noted across the analyzed studies.
Conclusions:
- Perfectionism interventions appear highly beneficial for disordered eating and perfectionism, and moderately for depression and anxiety.
- Eating disorder treatments may particularly benefit from integrating perfectionism interventions.
- Further research with diverse populations is needed to confirm generalizability.
