Higher FHD was associated with greater drinking intensity in the COGA sample (p = 0.0002; Score Test p = 0.54, Figure S1). Individuals with a higher FHD were 7.75 times more likely to be in the extreme‐risk DI group compared with the other DI groups (based on unit of 0.25 in FHD calculation; 95% confidence interval (CI) = [1.45, 40.76]). FHD was not associated with any of the alcohol‐related screening measures (all ps > 0.30) in the laboratory sample.
