Stok, F. Marijn Perceiving college peers' alcohol consumption : temporal patterns and individual differences in overestimation Stok, F. Marijn Objective: This study examines temporal patterns and individual differences of overestimation in alcohol norm perception within a social network.<br /><br />Design: Hundred psychology freshmen indicated biweekly during their first semester the drinks they consumed, the perceived average of their peers’ consumption, and with whom they were acquainted. At baseline, trait self-control was assessed.<br /><br />Main outcome: The moderation of alcohol consumption overestimation by time and individual characteristics was explored.<br /><br />Results: Results show that students overestimated alcohol consumption of their acquainted peers by 1.22 drinks (p < .001). For time periods at which peers reported high consumption, overestimation decreased. Additionally, individuals reporting high alcohol consumption (b = −0.25, p < .001) and low self-control (b = 0.27, p = .010) showed higher overestimation.<br /><br />Conclusions: Students overestimate the alcohol consumption of peers not fully accounting for changes in peer-reports. Furthermore, individual differences suggest informational and motivational processes underlying overestimation. 2019-02 Giese, Helge Giese, Helge eng 2019-03-06T14:18:54Z 2019-03-06T14:18:54Z Renner, Britta Renner, Britta
