Summary
The Stop Sexual Harassment (SSH) program did not significantly reduce sexual and gendered harassment among adolescents in Norwegian schools. This school-based intervention showed no improvement compared to a control group.
Area of Science:
- Adolescent Health
- Public Health Interventions
- Educational Psychology
Background:
- Sexual and gendered harassment is common among adolescents, impacting their health.
- Existing research on school-based interventions for this age group is limited.
- The Stop Sexual Harassment (SSH) program aimed to address this gap.
Purpose of the Study:
- To evaluate the effectiveness of the SSH program in reducing sexual and gendered harassment.
- To assess both victimization and perpetration of harassment.
- To provide evidence for school-based prevention strategies.
Main Methods:
- A cluster-randomized controlled superiority trial involving 41 Norwegian secondary schools and 2236 students (aged 13-15).
- Schools were randomized to the SSH intervention or a delayed-access control group.
- Primary outcomes measured self-reported harassment using validated scales at baseline and 2 months, analyzed via intention-to-treat.
Main Results:
- No statistically significant differences in sexual or gendered harassment were found between the intervention and control groups.
- Effect sizes for all primary outcomes were small and close to zero.
- Multiple imputation was used to address substantial missing outcome data.
Conclusions:
- The SSH program, as implemented, did not demonstrate effectiveness in reducing adolescent sexual and gendered harassment.
- Further research may be needed to explore alternative or modified intervention strategies.
- Findings suggest current school-based approaches may require re-evaluation.

01:27Halo Effect
The halo effect is a cognitive bias in which an individual's overall impression influences judgments about their specific traits. This psychological phenomenon leads people to associate positive characteristics with those they perceive as generally good and negative characteristics with those they view as bad. This effect is particularly influential in social perception, professional evaluations, and decision-making processes.The Psychological Basis of the Halo EffectThe halo effect is rooted...
01:13Randomized Experiments
The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.
