Friendship group norms as a correlate of seed behavior (n = 57 groups).

Note. To correct for cluster size, recreation and drug norms utilize an Empirical Bayes estimation of the group mean. Condom norms are based on the observed group mean because cluster values are extremely homogeneous obviating the need for the Empirical Bayes estimation method. OR: Odds ratio. The norm scores are adjusted to a unit value of 0.1 for all logit models; CI: confidence interval. p < 0.05*, 0.01**, 0.001***; ns = p > 0.06.
