This research examined the reliability and validity of the Change Agenda Implicit Relational Assessment Procedure (CA-IRAP). Change agendas that lead people to think that “reducing or removing undesirable thoughts and feelings will solve problems and lead to a more successful life” are considered unworkable in acceptance and commitment therapy (ACT). For acceptance-based interventions to succeed, relinquishing change agendas is important. However, currently available methods for measuring these types of change agendas are limited to explicit measures, which are vulnerable to distortion from social desirability and demand characteristics. The authors attempted to measure change agendas using the IRAP. A total of 131 undergraduate and graduate students (40 male, 91 female; mean age = 21.93, SD = 3.19) participated. First, we examined the CA-IRAP’s discriminant validity in relation to explicit measures such as the Acceptance and Action Questionnaire-II in 83 participants who were able to pass the CA-IRAP. The correlations between the CA-IRAP and the explicit measures were low, confirming the discriminant validity of the CA-IRAP. Second, we examined the predictive validity of the CA-IRAP. Nineteen respondents had learned ACT and 34 respondents had never learned ACT. Non-ACT learners’ CA-IRAP scores were higher than those of ACT learners, which confirmed the CA-IRAP’s predictive validity. Finally, we examined the CA-IRAP’s test–retest reliability, which was confirmed across some CA-IRAP trial types. In conclusion, the authors submit that the CA-IRAP has strong potential as a valid instrument for measuring the relative strength of relational responses around change agendas while controlling for variables such as demand characteristics.

这项研究检查了更改议程隐式关系评估程序（CA-IRAP）的可靠性和有效性。变革议程使人们认为“减少或消除不良思想和情感将解决问题并带来更成功的生活”在接受和承诺治疗（ACT）中被认为是行不通的。对于成功的基于接受的干预，放弃变更议程很重要。但是，目前用于衡量这些类型的变化议程的方法仅限于明确的措施，这些措施容易受到社会期望和需求特征的扭曲。作者试图使用IRAP来衡量变更议程。共有131名本科生和研究生（男40名，女91名；平均年龄= 21.93，SD= 3.19）。首先，我们检查了CA-IRAP与明确措施（例如，接受和行动问卷II）相关的判别效度，该83名参与者均通过了CA-IRAP。CA-IRAP与显式度量之间的相关性较低，证实了CA-IRAP的判别有效性。其次，我们检查了CA-IRAP的预测有效性。19名受访者学习了ACT，而34名受访者从未学习过ACT。非ACT学习者的CA-IRAP得分高于ACT学习者，这证实了CA-IRAP的预测效度。最后，我们检查了CA-IRAP的重测可靠性，这在某些CA-IRAP试验类型中得到了证实。结论，
