Pre- and Post-Surveys
help-seeking behavior
REGRESSION, SECONDARY
In primary statistical analysis (Aim 1), curriculum only and curriculum plus club schools were analyzed separately, using the same methods. Mixed effects linear and logistic regression models appropriate for longitudinal (repeated measures) data were used to analyze all survey items collected at each time point. The models contained a fixed effect for time (pre vs post) and random effects for school and student. The parameter for time was the primary parameter of interest in the model, as it indicates the change over time with intervention implementation. Parameter estimates and standard errors from the models are reported along with corresponding 95% confidence intervals and In secondary statistical analysis (Aim 2), curriculum only were compared directly to curriculum plus club schools regarding changes in knowledge, help-seeking behavior, and school culture. The same mixed effects regression models were used for each survey item, except the model also included a fixed-effect for group (curriculum only vs curriculum plus club) and a group by time interaction effect. All analyses were performed using SAS statistical software version 9.4 (SAS Institute, Cary, NC).
