The new normal: Changes in drinking norms from college to postcollege life

[Correction Notice: An Erratum for this article was reported in Vol 34(4) of Psychology of Addictive Behaviors (see record 2020-38542-001). In the article, the description of the prospective sample in the second sentence of the second paragraph and the second sentence of the third paragraph of the Participants section is incorrect. The description should appear, respectively, as follows: These were participants who were contacted if they reported at least one heavy drinking day (≥4 drinks for women and ≥5 drinks for men) in both a 30-day retrospective assessment and a 30-day daily diary reporting phase at Wave 1. . . . Of these, 1,141 were identified as moderate to heavy drinkers. Due to a coding error, 23 of these individuals did not meet these criteria but were contacted for Wave 2. However, all of these individuals reported drinking levels at Wave 1 (using a drinking composite comprised of standardized retrospective and daily diary drinking variables) within the range of values for the individuals who met the correct criteria. All were retained for analysis and 906 (79%) completed at least 15 days of recording in Wave 2.²] Despite the wealth of research on the effects of drinking norms on college students' alcohol consumption, researchers have not yet examined changes in drinking norms and their association with drinking level after students leave the college environment. The current study filled this gap by following students into postcollege life, measuring drinking norms and daily drinking behavior. College students (N = 1,848) were recruited to take part in a daily diary study measuring social and solitary alcohol consumption, and 1,142 moderate to heavy drinkers from the college cohort were invited to complete a second wave of daily diaries 5 years later, with 906 providing at least 15 days of diary data in each wave. Results of multilevel modeling analyses suggest that family injunctive drinking norms become more strongly related to alcohol consumption after individuals leave college. In contrast, institutional injunctive norms may have a greater limiting effect among college students (i.e., the association was greater among college students) and the relations between friend injunctive and descriptive norms to drinking behavior did not change between waves in the current study. This suggests that friend drinking continues to be related to own drinking behavior among adults after leaving the college environment, and highlights the changing importance of institutional norms and family approval. These results may have implications for intervening in young adults' heavy drinking. (PsycInfo Database Record (c) 2020 APA, all rights reserved).
