Although several multi-item scales assess readiness to change alcohol consumption, some researchers have proposed that a small number of single-item rulers may assess readiness nearly as well.
In fall 2006 and spring 2007, the authors assessed 279 participants who reported at least 1 heavy drinking episode in the 2 weeks prior to the survey.
The authors compared answers from the Readiness to Change Questionnaire with rulers measuring importance and confidence regarding change.
Importance correlated strongly with readiness to change, whereas confidence correlated negatively and less strongly with readiness. The validity of the importance ruler as a proxy for readiness was supported by its correlations with several measures of patterns of alcohol use, as well as its precursors and consequences.
Given the strong correlation between the importance ruler and the Readiness to Change score, this method may have practical utility as a brief assessment tool. Adding confidence as a second dimension slightly improved the ability to predict readiness.
尽管有几种多项目量表用于评估改变饮酒行为的准备情况，但一些研究人员提出，少数单项目量表可能也能较好地评估准备情况。
在2006年秋季和2007年春季，作者对279名参与者进行了评估，这些参与者在调查前两周内至少报告了1次重度饮酒事件。
作者将改变准备情况问卷的答案与衡量改变的重要性和信心的量表进行了比较。
重要性与改变准备情况密切相关，而信心与准备情况呈负相关且相关性较弱。重要性量表作为准备情况替代指标的有效性得到了其与多种饮酒模式测量指标及其前因后果的相关性的支持。
鉴于重要性量表与改变准备情况得分之间的强相关性，该方法作为一种简短的评估工具可能具有实际应用价值。将信心作为第二个维度添加进来，稍微提高了预测准备情况的能力。
