Implementing Strong Teens for Adolescent Girls in Residential Treatment: A Quasi-Experimental Evaluation

ABSTRACT

Adolescents in residential treatment centers (RTCs) often have a severe mental illness as well as significant deficits in their social competencies. Strong Teens is a social and emotional learning (SEL) curriculum designed to decrease internalizing disorders by promoting emotional resilience and social competence. The curriculum has shown promising effects in educational settings. This study is the second to implement Strong Teens in residential treatment with high-risk adolescents. Using a quasi-experimental wait-list control design, therapists implemented Strong Teens with 36 adolescent girls in an RTC during group therapy. The researchers assessed changes in social and emotional knowledge, internalizing symptoms, and resilience using a split-plot repeated measures ANOVA, paired samples t-tests, and effect sizes. Although results indicated that Strong Teens did not affect the girls’ social and emotional knowledge, the intervention did show evidence of reducing their internalizing symptoms and increasing their resilience. In a social validity survey, most group therapists agreed with the goals and procedures of the curriculum but were less certain regarding the outcomes. We recommend that future studies of this population investigate which SEL topics are most suitable, identify the most favorable lesson times for RTC implementation, and explore student perspectives and experiences with Strong Teens.
