Although many members of Alcoholics Anonymous (AA) are introduced to AA during treatment, the relationship between treatment and AA attendance over time is unknown. This paper describes four latent classes of AA attendance among 586 dependent alcoholics interviewed by telephone 1, 3, 5 and 7 years after baseline, and models the relationship between treatment exposure and AA attendance in each class. There was a low AA group (averaging fewer than 5 meetings at most follow-ups), a medium AA group (about 50 meetings a year at each follow-up), a descending AA group (about 150 meetings year 1, then decreasing steeply), and a high AA group (about 200 meetings at 1 year, then decreasing gradually by year 7). Declines in meeting attendance were not always accompanied by decreases in abstinence. After accounting for the effect of time on AA attendance (i.e., the "ups-and-downs" that occur over time), treatment exposure was minimally related to AA attendance in all but the descending AA group, where it was negatively associated (p<0.001). Considering AA patterns over time highlights a different role for treatment in AA attendance than what is gleaned from analyses at single timepoints.
虽然许多酗酒者匿名互助会（AA）的成员是在治疗期间被介绍到 AA 的，但随着时间的推移，治疗与 AA 出勤率之间的关系尚不清楚。本文描述了在基线后 1、3、5 和 7 年通过电话采访的 586 名依赖酒精的酗酒者中，AA 出勤率的四个潜在类别，并为每个类别中的治疗暴露与 AA 出勤率之间的关系建模。存在一个低 AA 群体（大多数随访中平均参加的会议少于 5 次）、一个中等 AA 群体（每年大约 50 次会议）、一个下降的 AA 群体（每年约 150 次会议，然后急剧下降）和一个高 AA 群体（每年约 200 次会议，第 1 年下降，然后逐渐下降到第 7 年）。出席会议的人数下降并不总是伴随着禁欲的减少。在考虑 AA 出勤率随时间的影响（即随时间发生的“起伏”）后，治疗暴露与除下降的 AA 群体外的所有 AA 出勤率均呈最小相关，而在下降的 AA 群体中则呈负相关（p<0.001）。考虑到 AA 模式随时间的变化，治疗在 AA 出勤率方面的作用与在单一时间点分析中得出的作用不同。
