We investigated the test-retest reliability of the 2-minute walk test (2MWT) and its’ concurrent validity with the 6-minute walk test (6MWT) in Ugandan outpatients with alcohol use disorder (AUD). We also explored practice effects, and assessed the minimal detectable change (MDC) and correlations with the 2MWT. Fifty outpatients [7 women; median age=32.0 years] performed the 2MWT twice, the 6MWT once and completed the Simple Physical Activity Questionnaire, Brief Symptoms Inventory-18 (BSI-18), and Alcohol Use Disorders Identification Test. The median (interquartile) 2MWT score on the first and second test were 162.0 (49.0) meters and 161.0 (58.0) meters, respectively, without significant difference between the two trials (P=0.20). The intraclass correlation between the two 2MWTs was 0.96 (95% confidence interval=0.94-0.98). The Spearman Rho correlation between the second 2MWT and the 6MWT was 0.91 (P<0.001). The MDC for the 2MWT was 18 meters. There was no evidence of a practice effect. Variance in BSI-18 depression, and the presence of leg pain following the 2MWT explained 18.7% of 2MWT score variance. The 2MWT is a reliable and valid fitness test, which can be conducted without any special equipment or substantial time demands in outpatients with AUD.

我们调查了乌干达酒精使用障碍 (AUD) 门诊患者 2 分钟步行测试 (2MWT)的测试- 重测信度及其与 6 分钟步行测试 (6MWT) 的同时有效性。我们还探讨了实践效果，并评估了最小可检测变化 (MDC) 和与 2MWT 的相关性。50 名门诊患者 [7 名女性；中位年龄 = 32.0 岁] 进行了两次 2MWT，一次 6MWT，并完成了简单体力活动问卷、简要症状量表 - 18 (BSI-18) 和酒精使用障碍识别测试。第一次和第二次测试的中位数（四分位间距）2MWT 分数分别为 162.0（49.0）米和 161.0（58.0）米，两次试验之间没有显着差异（P=0.20）。两个 2MWT 之间的组内相关性为 0.96（95% 置信区间 = 0.94-0.98）。第二次 2MWT 和 6MWT 之间的 Spearman Rho 相关为 0.91 (P<0.001)。2MWT 的 MDC 为 18 米。没有证据表明练习效果。BSI-18 抑郁的差异和 2MWT 后腿部疼痛的存在解释了 18.7% 的 2MWT 评分差异。2MWT 是一种可靠且有效的体能测试，无需任何特殊设备或对 AUD 门诊患者的大量时间要求即可进行。
