最初的动机和准备改变（RTC）是复杂的结构，并一直是重要的，但不一致的预测治疗出勤率和饮酒的结果在酗酒治疗的研究。动机可以用多种方式来描述，简单地说，就是推动变化的结果的积累，意图的转变，或者参与各种任务，这些任务是更大的变化过程的一部分。这项研究重新评估了一个24-来自罗得岛大学变化评估量表的动机项目测量，该量表产生了4个分量表，代表与沉思前阶段任务相关的态度和经验，沉思，行动，和维护努力，以及二阶因子得分代表RTC饮酒的多维视图。各种假设的预测因子的准备和阶段分量表进行了检查，使用多元回归分析，以更好地了解这种措施的动机的性质，调查结果支持的基本分量表结构和整体动机准备得分来自这个措施。RTC饮酒行为通过感知压力、饮酒严重程度、精神共病、自我效能、渴望和积极治疗结果预期的基线测量进行预测。然而，绝对值很小，表明准备改变是不是简单地解释人口，饮酒严重程度，治疗，改变过程中，或contextual variables.This措施表现出良好的心理测量特性和结果支持的独立性，以及收敛和发散效度的测量结构。整体准备和分量表分数的预测表明，各种个人和背景因素有助于治疗寻求者的动机，以一种可以理解的，但复杂的方式改变。
Initial motivation and readiness to change (RTC) are complex constructs and have been important but inconsistent predictors of treatment attendance and drinking outcomes in studies of alcoholism treatment. Motivation can be described in multiple ways as simply the accumulation of consequences that push change, a shift in intentions, or engagement in various tasks that are part of a larger process of change.Using baseline data from participants in the COMBINE Study, this study reevaluated the psychometric properties of a 24-item measure of motivation derived from the University of Rhode Island Change Assessment Scale that yielded 4 subscales representing attitudes and experiences related to tasks of stages of Precontemplation, Contemplation, Action, and Maintenance Striving as well as a second-order factor score representing a multidimensional view of RTC drinking. A variety of hypothesized predictors of readiness and the stage subscales were examined using multiple regression analyses to better understand the nature of this measure of motivation.Findings supported the basic subscale structure and the overall motivational readiness score derived from this measure. RTC drinking behavior was predicted by baseline measures of perceived stress, drinking severity, psychiatric comorbidity, self-efficacy, craving, and positive treatment outcome expectancies. However, absolute values were small, indicating that readiness for change is not explained simply by demographic, drinking severity, treatment, change process, or contextual variables.This measure demonstrated good psychometric properties and results supported the independence as well as convergent and divergent validity of the measured constructs. Predictors of overall readiness and subscale scores indicate that a variety of personal and contextual factors contribute to treatment seekers' motivation to change in an understandable but complex manner.
