aSignificance calculated on adjusted mean change between baseline and each followup. Multilevel modeling (MLM) analysis adjusted for intervention group, evaluation times, interaction between intervention group and evaluation times, age, gender, religious group (any religion versus nonreligion), and socio-economic status. *; **; ***. EWA: exploring the world of adolescents (youth program); PMT: protection motivation.
