Note. Two Repeated-Measures Mixed Effect Models. Intention to smoke and knowledge were assessed 3 days before treatment and by the end of a one-month-long treatment (i.e., 33 days post-baseline assessment). ASPIRE stands for a smoking prevention interactive experience. PSI stands for positive social influence. SE stands for standard error.
