In a 2012 study, researchers recruited 20 people as drinkers, and 20 others to serve as controls who stayed sober.

在 2012 年的一项研究中，研究人员招募了 20 人为饮酒者， 20 清醒者为对照。

While controls, usually people who don't get any therapy, often do get better on their own, those in psychotherapy usually improve faster, and with a significantly lower risk of relapse.

对照者，通常是未接受任何治疗的人，通常会自行好转， 而那些接受治疗的人通常改善得更快， 并且复发风险显着降低。
