How do Bystanders Help in Drinking Situations: The Bystanders to Alcohol Risk Scale - Strategies.

Bystander intervention (BI) is a promising approach for promoting collective behavior change that has been applied to several domains, including sexual assault, bullying, and more recently problematic alcohol use. Accurately measuring the strategies that bystanders use to reduce others' alcohol-related risk is an essential step towards improving bystanders' ability to reduce alcohol-related harm in their communities, but current measures of BI are not easily modifiable and applicable for alcohol-related BI. The current study aimed to develop a valid and reliable measure of the bystander construct most proximal to the reduction of risk: bystander strategies. Young adults ( An initial set of 52 items was reduced to 17 items, representing two different factors. The first factor, Level One, reflected strategies used during circumstances of acute risk. The second factor, Level Two, reflected strategies used to reduce risk for more longstanding problems with alcohol. Both factors demonstrated good model fit, strong internal consistency, evidence of convergent validity, and moderate test-retest reliability. This novel measure can contribute to the production of knowledge about the use and efficacy of peer-focused strategies and the value of BI training for alcohol use.
