This systematic review examined the effectiveness of school social work practices using meta-analytic techniques.
Hierarchical linear modeling software was used to calculate overall effect size estimates as well as test for between-study variability.
A total of 21 studies were included in the final analysis. Unconditional random effects model shows an overall weighted mean effect size estimate of .23 for externalizing problem outcomes and .40 for internalizing problem outcomes; both categories were statistically significant at the p < .05 level. Subgroup analysis for academic outcomes showed mixed results for knowledge, attendance, and grade point average outcome measures.
Results highlight the positive impact school social workers may have on student emotional, mental, behavioral, and academic outcomes.
