A mixed‐methods approach to improve the measurement of alcohol‐induced blackouts: ABOM‐2

摘要: Background Alcohol‐induced blackouts describe memory loss resulting from alcohol consumption. Approximately half of college students report experiencing a blackout in their lifetime. Blackouts are associated with an increased risk for negative consequences, including serious injury. Research has documented two types of blackouts, en bloc (EB) and fragmentary (FB). However, research is limited by the lack of a validated measure that differentiates between these two forms of blackout. This study used a mixed‐methods approach to improve the assessment of FB and EB among young adults. Specifically, we sought to improve the existing Alcohol‐Induced Blackout Measure (ABOM), which was derived from a relatively small pool of items that did not distinguish FB from EB. Methods Study 1 used three rounds of cognitive interviewing with U.S. college students (N = 31) to refine existing assessment items …
