Developing brief measures of motivation to abstain from substance use that reliably predict treatment retention and outcome is a high priority in the addiction field. This study examined the psychometric properties of a contemplation ladder designed to assess readiness to abstain from alcohol and drug use respectively, on the basis of the contemplation ladder for smoking cessation developed by Biener and Abrams (1991). Participants were 394 substance-using male and female welfare recipients referred for treatment. The combined alcohol and other drug (AOD) ladder showed discriminant validity with demographic and health characteristics, convergent validity with conceptually related treatment motivation variables, concurrent validity with baseline AOD treatment and substance use variables, and predictive validity for participation in treatment services up to 1 month later and abstinence outcomes up to 1 year later. The AOD ladder showed predictive validity for those in drug-free treatment and no treatment at baseline but not for those in methadone maintenance.
开发简短的戒除物质使用动机的测量工具，这些工具能够可靠地预测治疗保留率和结果，这是成瘾领域的一个高度优先事项。本研究基于 Biener 和 Abrams（1991）开发的戒烟思考梯，检验了评估分别戒除酒精和药物使用的思考梯的心理测量学特性。参与者为 394 名接受治疗的男性和女性福利接受者，他们都有物质使用问题。酒精和其他药物（AOD）综合思考梯在人口统计学和健康特征方面具有判别有效性，与概念上相关的治疗动机变量具有收敛有效性，与基线 AOD 治疗和物质使用变量具有同时有效性，并能预测 1 个月后参加治疗服务和 1 年后的戒断结果。该 AOD 思考梯对那些在基线时未接受美沙酮维持治疗和未接受任何治疗的人具有预测有效性，但对接受美沙酮维持治疗的人则不具有预测有效性。
