DeRosier, M. E. (2004). Building relationships and combating bullying: Effectiveness of a school-based social skills group intervention. Journal of Clinical Child and Adolescent Psychology, 33. 125-130.


This study tested the efficacy of a generic social skills intervention, Social Skills Group Intervention (S.S.GRIN), for children experiencing peer dislike, bullying, or social anxiety. Third-grade children were randomly assigned to treatment (n = 187) or no-treatment control (CO; n = 194) groups. Examination of the direction and magnitude of change in functioning revealed that S.S.GRIN increased peer liking, enhanced self-esteem and self-efficacy, and decreased social anxiety compared to controls. S.S.GRIN was equally efficacious for all subtypes of peer problems targeted. Particular benefits were found for aggressive children who showed greater declines in aggression and bullying behavior and fewer antisocial affiliations than aggressive control participants.

Discussion focuses on the benefits of heterogeneous versus homogeneous groups of participants and the potential value of utilizing generic social skills training protocols.

This study tested the long-term effectiveness of a social-skills program for peer-rejected, victimized, and socially anxious children. Third-grade children with peer problems were randomly assigned to treatment (TX; n = 187) or no-treatment control (CO; n = 194) groups. One year after the intervention, the pattern of findings was similar to that at post-intervention; however, several new group differences emerged.

Additional positive treatment effects were found, including higher social acceptance and self-esteem and lower depression and anxiety. Lower aggressive behavior was found, particularly for initially more aggressive children. Several gender differences emerged where treatment effects were present for girls but not boys. The demonstrated value of teaching social skills to children experiencing peer problems is discussed and suggestions for future research are offered.

Results for students who participated in S.S.GRIN 3-5:

  • Significant reductions in peer nominated aggression, bullying behavior, and fear of negative evaluation. 
  • Significant differences between treatment and control groups on antisocial affiliations and depression when compared to controls. 
  • Significant improvement in social motivation.


Schools are required to use a system of accountability called Response to Intervention (RTI) and Positive Behavioral Interventions and Supports (PBIS). A number of states are moving to the Multi-tiered System of Supports (MTSS) model to incorporate RTI and PBIS.

MTSS is designed to ensure that educators provide high-quality instruction and intervention matched to student needs using (1) learning rate over time and (2) level of performance to inform instructional decisions.

S.S.GRIN K-2 Alignment with RTI, PBIS, and MTSS

S.S.GRIN K-2 meets the Tier 2 requirements of these models by providing a targeted behavioral intervention for students who need extra support to improve their social skills.
