摘要

Food and alcohol disturbance (FAD) refers to partaking in disordered eating behaviors before, during, and/or after consuming alcohol to offset calories or enhance alcohol’s effects. While interest in FAD has grown, more precise, theoretically informed measurement tools are needed. We tested the factor structure, group invariance, and convergent validity of the revised College Eating and Drinking Behavior Scale (CEDBS-R) among college students from six universities. Participants were split into two samples (sample A: N = 2016, 77.4% female, 62.7% White non-Hispanic, Mage = 19.24, SD = 1.89; sample B: N = 1060, 69.6% female, 67.8% White non-Hispanic, Mage = 19.80, SD = 2.58). A two-factor solution with 12 items—alcohol enhancement (5 items; ω = .909) and caloric compensation (7 items; ω = .908)—demonstrated good model fit, CFI = .961, TLI = .952, RMSEA = .050, SRMR = .059, and was scalar invariant across sex assigned at birth. Both subscales demonstrated convergent validity with measures of alcohol use and disordered eating constructs. The two factors align with the theoretical and empirical research on FAD, providing valuable insights into not only the frequency of FAD but also into the underlying motives driving these behaviors. This represents a significant advancement in FAD assessment.
