Note. d = weighted mean difference; QB = between-categories homogeneity index with number of levels of factor – 1 degree of freedom. Differences are differences between the d when the strategy was present versus absent. Significant QBs indicate significant effects of the interventions relative to control study groups. The first QB in the table compared the effect at the time of the immediate follow-up and the second at the time of the delayed follow-up. The comparison F reflects changes in QBs from immediate to delayed follow-up. The weighted means for control study groups at immediate follow-up were perceived risk d = 0.01, knowledge d = 0.08, and condom use d = 0.04. The weighted means for control study groups at delayed follow-up were perceived risk d = −0.07, knowledge d = 0.11, and condom use d = −0.03.
