Ondertitel:testing effects of seeking, scanning, and trust in sources on attitudes toward marijuana
This study uses a three-wave prospective longitudinal survey (at 6-month intervals) to test effects of information seeking and scanning on attitudes toward marijuana among college students in Israel (N = 700). We integrate constructs from the elaboration likelihood model to contrast processes of attitude change among individuals who vary in moderators of information processing depth (motivation and ability). In addition, we test whether trust in the information source moderates these processes, and use propensity score matching to reduce bias. Results of autoregressive cross-lagged structural equation models show that scanning from interpersonal sources predicted attitudes toward marijuana among individuals who were low in elaboration motivation or ability. Seeking and scanning information about marijuana from interpersonal sources were positively associated with attitudes toward marijuana among individuals higher in elaboration motivation and ability, who had greater trust in the source. Implications for information processing models, seeking and scanning, and campaigns are discussed.
