Although past \u2018variable\u2010centered\u2019 (e.g. factor\u2010analytic) studies have demonstrated the importance of these clusters, the current study aimed to examine how these clusters commonly manifest using a \u2018person\u2010centered\u2019 approach (e.g. latent class).<\/jats:p><\/jats:sec><jats:sec><jats:title>Design<\/jats:title><jats:p>Cross\u2010sectional in\u2010person assessment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Setting<\/jats:title><jats:p>Indiana, USA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Participants<\/jats:title><jats:p>A convenience sample of 1390 young adults (mean age\u2009=\u200921.43, SD\u2009=\u20092.47) recruited for an over\u2010representation of alcohol problems (65% with AUD).<\/jats:p><\/jats:sec><jats:sec><jats:title>Measurements<\/jats:title><jats:p>Latent class analysis (LCA) was conducted on 23 criteria from the Semi\u2010Structured Interview on the Genetics of Alcoholism (SSAGA) that align with DSM\u2010V AUD symptoms.
