However, longer TLFB windows can increase burden for participants and study staff. This study assessed youth alcohol use patterns across two different 30\u2010day periods (TLFB days 1\u201330 and 31\u201360) to inform future research protocols.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Participants (\n                      <jats:italic>N<\/jats:italic>\n                      \u2009=\u2009481 with 504 visits, ages: 15\u201325) completed a shared intake to determine eligibility for numerous substance\u2010related studies. Alcohol consumption over the past 60\u2009days was assessed using a modified TLFB that recorded total number of drinks, average drinks per day, average drinks per drinking day (DPDD), total number of drinking days, maximum number of drinks in a single day, and total number of binge drinking days (4+ drinks for females, 5+ drinks for males). TLFB data were divided into two 30\u2010day periods: the most recent (Days 1\u201330) and the more distal (Days 31\u201360). Analyses were conducted overall and within subgroups by sex, age (under 21 or 21+), presence of alcohol use disorder (AUD), and other substance use. Alcohol use patterns were assessed using Spearman correlations, Wilcoxon signed rank tests, and intraclass correlations (ICC) for test\u2013retest reliability.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      All alcohol outcomes were significantly correlated between reporting windows (\n                      <jats:italic>p<\/jats:italic>\n                      's\u2009&lt;\u20090.001).

Overall, the differences between reporting windows were small (on average, less than three total drinks and &lt;1 drinking day or binge drinking day) and suggested clinically similar use patterns. The ICC values suggest moderate\u2010to\u2010good stability between reporting windows.
