q3 · i? · quant-synthesis · r3

Meta-ANOVA moderator analysis for the bullying-achievement relationship. Design was a significant moderator (Qb = 11.26, p = 0.001), with longitudinal studies showing a stronger effect (OR = 0.43) than cross-sectional studies (OR = 0.85); age, assessment method, country and bullying type were also significant moderators.

"The heterogeneity assessment indicated that the relationship was also significantly moderated by study design (Qb = 11.26, p = 0.001). This indicated that bullying involvement had a stronger effect on academic achievement in longitudinal studies (k = 7, OR = 0.43, p = 0.000) compared with cross-sectional studies (k = 7, OR = 0.85, p = 0.006)."
