The authors compared 3 measures of readiness to change alcohol use commonly used in clinical research and practice with adolescents: the Readiness Ruler, the SOCRATES (subscales of Recognition and Taking Steps), and a Staging Algorithm. The analysis sample consisted of 161 male and female adolescents presenting for intensive outpatient alcohol-abuse treatment who reported current alcohol use at the initial assessment. Evidence for concurrent validity was assessed by computing simple correlations of each readiness measure with the other 3 and of each readiness measure with drinking behavior (percentage of days abstinent [PDA] and drinks per drinking day [DDD], respectively, in the last 30 days) at the start of treatment and at the 6-month follow-up assessment. Evidence for predictive validity was based on percentage of independent variance accounted for by each of the readiness measures in predicting drinking behavior at 6 months from the start of treatment, and then in predicting drinking behavior at 12 months from the readiness assessment at 6 months. The results showed that all but Recognition had good concurrent validity, the Readiness Ruler score showed consistent evidence for predictive validity, and the Staging Algorithm showed good predictive validity for DDD at 6 and 12 months. For the 82 participants with an alcohol-use disorder diagnosis, the findings for the Ruler and Recognition were similar, but the Staging Algorithm had poorer prediction of DDD at 12 months, and Taking Steps was a better predictor of 6- and 12-month PDA and DDD. Research and clinical implications of the findings are discussed.
准备程度尺、SOCRATES（识别和采取措施的子量表）和分期算法。分析样本包括 161 名男性和女性青少年，他们在最初评估时报告了当前的饮酒情况，并在门诊强化治疗中就诊。通过计算每个准备程度量表与其他 3 个量表以及每个准备程度量表与治疗开始时和 6 个月随访评估时饮酒行为（过去 30 天内的无饮酒天数百分比 [PDA] 和每天饮酒量 [DDD]）之间的简单相关性，评估了同时效度的证据。预测效度的证据基于每个准备程度量表在治疗开始后 6 个月预测饮酒行为的独立方差百分比，然后在治疗开始后 6 个月的准备程度评估中预测 12 个月的饮酒行为。结果表明，除了识别，所有量表都具有良好的同时效度，准备程度尺的评分具有一致的预测效度，分期算法在 6 个月和 12 个月时都具有良好的 DDD 预测效度。对于 82 名患有酒精使用障碍诊断的参与者，尺和识别的结果相似，但在 12 个月时，分期算法对 DDD 的预测较差，而采取措施是预测 6 个月和 12 个月 PDA 和 DDD 的更好指标。讨论了这些发现的研究和临床意义。
