本研究探讨了沉思阶梯和罗得岛大学变化评估（URICA）的收敛和并发效度。对两项同期研究招募的参与者的摄入数据进行了分析。一组（n = 77）没有计划在未来6个月内戒烟，而第二组（n = 106）有明确的戒烟计划。除就业状况外，两组在任何人口统计变量上都没有差异。整个样本（n = 183）的沉思阶梯评分与URICA沉思和行动子量表评分呈正相关，但与沉思前子量表评分呈负相关。沉思阶梯也与URICA综合评分呈正相关。此外，在接下来的6个月内寻求戒烟的参与者的沉思阶梯和URICA沉思，行动和综合评分显着较高，但比不寻求戒烟的参与者的沉思前评分较低。控制就业状况并没有改变结果的模式。我们的研究结果为这两种测量方法的收敛性和并发有效性提供了支持，并表明在某些情况下，单项沉思阶梯可能是URICA的实用替代方案。(C)2003爱思唯尔爱尔兰有限公司保留所有权利。
This study examined the convergent and concurrent validity of the Contemplation Ladder and the University of Rhode Island Change Assessment (URICA). Intake data of participants recruited into two concurrent studies were analyzed. One group (n = 77) had no plans to quit smoking within the next 6 months, while a second group (n = 106) had definite plans to quit. The groups did not differ on any demographic variables except employment status. Contemplation Ladder scores for the entire sample (n = 183) correlated positively with the URICA Contemplation and Action subscale scores but negatively with Precontemplation subscale scores. The Contemplation Ladder also correlated positively with the URICA Composite score. Additionally, participants seeking to quit within the next 6 months had significantly higher Contemplation Ladder and URICA Contemplation, Action, and Composite scores, but lower Precontemplation scores than participants not seeking to quit. Controlling for employment status did not change the pattern of results. Our findings provide support for the convergent and concurrent validity of these two measures and suggest that the single-item Contemplation Ladder may be a practical alternative to the URICA in certain situations.
