Abstract
The “Change Agenda” is a rule that psycho−behavioral problems can be solved if private events are controlled. It is considered a maintaining factor of experiential avoidance that is defined as an attempt to avoid private events. However, no tool has been developed to measure the Change Agenda. Therefore, this study aimed to develop a measurement of the conviction degree in the Change Agenda (CAQ−believability) and the behavior according to it (CAQ−
avoidance), and investigate its reliability and validity. The structural validities of CAQ−believability and CAQ−avoidance were generally sufficient. Cronbach’s α was sufficiently high and good test–retest reliability was observed. With regard to convergent validity, CAQ−believability and CAQ−avoidance generally exhibited hypothesized correlation patterns.
Moreover, between the clinical and the student samples examined in this study, scores of CAQ−believability and CAQ−avoidance were higher in the clinical sample than in the student sample. These results indicate that the reliability and validity of CAQ were generally acceptable. In the field of psychological treatment, expanding behavioral repertoire and improving the quality of life are the most important goal; the CAQ can be used as a tool to achieve this goal.
