Abstract |
Heavy episodic drinking (4+/5+ drinks/occasion for females/males) is highly prevalent among college students and is influenced by social factors. Among these social risk factors, perceived peer drinking norms have been shown to significantly predict heavy episodic drinking across a number of studies. However, there is little known about which students may be most and least susceptible to these influences or why individual differences may moderate the impact of norms on heavy drinking. Recent work has suggested self-control may be an important individual difference factor in this regard. Working memory (WM) is a central component of self-control that has been shown to buffer the effect of social influence variables. This study examined whether WM, as measured by memory span tasks, moderates the relationship between perceived drinking norms and alcohol use among college students reporting one or more past month drinking occasions (n = 98). Hierarchical linear regression analyses were used to examine whether WM significantly moderated the relationship between perceived norms and heavy drinking episodes (HDEs) as well as number of drinking days in the past month. Analyses revealed a significant WM x norms interaction for both drinking indices. Simple slopes analyses suggested a buffering effect of WM as higher perceived norms predicted more HDEs and drinking days at low (-1SD) and mean WM scores but not high (+1SD) WM. These results suggest WM serves as a protective factor for the influence of norms such that individuals high in WM may be more able to inhibit the impact of norms on alcohol use. Language: en |
