The final sample included 820 participants [age: 19.63 ± 1.24 years; 464 (56.58%) female; ethnicity: 373 (45.4%) European/European American, 223 (27.2%) Asian/Asian-American, 88 (10.7%) African/African-American, 52 (6.3%) Hispanic, 84 (10.2%) multiracial or other]. While the majority of participants were healthy (81.82%), some of our sample met criteria for one or more Axis I disorders (18.17%) according to a diagnostic interview (Supplementary Table S1). Based on normative data (Boschen & Oei, 2007) 10.2% and 7.8% of our participants demonstrated scores comparable to those observed in depression clinical samples for the depression and anhedonic depression scales respectively. Additionally 2% of our sample self-reported AUDIT scores equal to or above clinical samples who meet criteria for alcohol dependence (Donovan et al. 2006).
