Are counselor-led SEL interventions effective? Insights from a recent meta-analysis

By Carmen Pannone, University of Cagliari

Social and emotional learning (SEL) interventions help students, educators, and school staff manage emotions, build relationships, and make thoughtful decisions. These programs are linked to improved academic performance and overall well-being. School counselors are crucial in implementing SEL programs but often face challenges due to limited resources, such as limited time and training. As students face increasing mental and social challenges, understanding the impact and best practices for these interventions is essential.

A recent meta-analysis reviewed the effectiveness of school counselor-led SEL interventions, including 28 studies published over the past 20 years. Using a random effects model, the analysis found an average statistically significant positive effect (ES = +0.31). Subgroup analyses and meta-regression revealed that while no moderators showed statistically significant differences, several factors were associated with larger effect sizes. Notably, larger effect sizes were observed in randomized controlled trials (RCTs) (ES =+0.31) and cluster RCTs (ES = +0.42) in samples with over 50% racial/ethnic minority students (ES = +0.40 versus ES = +0.21 in samples with less diversity). Effects were larger for low SES groups (ES = +0.35 compared to +0.21 for higher SES group), and for middle (ES = +0.45) and high school students (ES = +0.43) compared to elementary students (ES = +0.08). The interventions were more effective for academic development (ES = +0.41) than for social-emotional (ES = +0.19) or career development (ES = +0.14). Small group interventions showed the highest effect (ES = +0.44), followed by classroom lessons (ES = +0.30). Interventions grounded in theory had larger effects (ES = +0.41 for multiple theories, ES = +0.32 for a single theory) compared to those without theoretical grounding (ES = +0.17). Applying theory to measure changes in relevant constructs led to larger effects (ES = +0.34) compared to those that did not (ES = +0.26), and discussing results in relation to theory also showed higher effect sizes (ES = +0.40 vs. +0.27).

Despite the limitation of including only peer-reviewed published papers, which may lead to an overrepresentation of positive findings, this meta-analysis suggests that school counselors contribute significantly to SEL-related outcomes, especially for academic achievement. Additionally, the integration of theory in SEL programming seems to be associated with more impactful intervention results.
