The Association Between Secondhand Harms From Alcohol and Mental Health Outcomes Among Postsecondary Students.

OBJECTIVE
There is a paucity of research on the prevalence and consequences of secondhand harms from alcohol. The current study (a) investigated whether secondhand harms can be clustered into latent factors that reflect distinct but related types of harms and (b) examined the associations between experiencing secondhand harms and mental health outcomes, including anxiety, depression, and subjective mental well-being, among first-year Canadian postsecondary students. The moderating effect of living arrangement (i.e., living on campus or not) on the associations was also tested.


METHOD
The sample included 1,885 first-year undergraduate students (49.8% female; mean age = 18.31 years) from three Canadian universities. Exploratory and confirmatory factor analyses were used to determine the factor structure of the harms measure. Path analysis was used to assess the association between harms and mental health outcomes. Models accounted for age, sex, and frequency of heavy drinking.


RESULTS
Seventy-one percent of the sample reported experiencing at least one type of secondhand harm. The harms examined clustered into two distinct but related factors: strains (e.g., interrupted sleep) and threats (e.g., being harassed or insulted). Both threats and strains were associated with higher levels of anxiety and depression and poorer subjective well-being. Associations were stronger for threats and did not differ by living arrangement.


CONCLUSIONS
Experiencing secondhand harms from alcohol, particularly threats, may have negative implications for student mental health over and above students' own drinking. Programs and policies on university campuses targeting both alcohol use and mental health should consider how to reduce both the prevalence and impact of secondhand harms from alcohol on students.
