COGA participants completed comprehensive diagnostic clinical interviews (SSAGA) from which documentation about their past and present status of alcohol-related symptoms and diagnosis was gathered and used to determine whether they satisfied DSM-5 criteria for AUD (APA, 2013; Bucholz et al., 1994; Dick et al., 2023), along with a battery of EEG assessments, including resting state recordings (Meyers et al., 2023). Participants were told to arrive sober for the EEG recording session and they were rescheduled if they had a positive breath alcohol test. In this study, associations between AUD diagnosis and PAC were assessed using EEG recordings acquired during the resting state eyes closed condition as part of the COGA project. Detailed information on EEG collection in COGA is available in our previous publications (Begleiter et al., 1995; Meyers et al., 2023; Rangaswamy et al., 2002).
