Participants completed an acceptability survey post\u2010intervention, and a subset were interviewed to provide additional feedback. Measures of recovery organization engagement and alcohol use were collected pre\u2010intervention, post\u2010intervention, and at 1\u2010month post\u2010intervention and summarized using descriptive statistics.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The recruitment rate was 10 participants per month, and 76.7% of enrolled participants completed the post\u2010treatment assessment.
