The purposes of the present study were to develop a questionnaire to measure the Acceptance and Commitment Therapy (ACT) core behavior processes of “Values” and “Committed Action” and to confirm the questionnaire’s reliability and validity. In Study 1, exploratory factor analysis indicated that the new questionnaire had a 3-factor pattern: “Increased Motivation,” “Continuing Behavior,” and “Awareness of Reinforcement.” Furthermore, Study 1 indicated that the questionnaire had adequate internal consistency and convergent and discriminant validity. Study 2 examined the questionnaire’s construct validity, using structural equation modeling (SEM). The results revealed that as “Awareness of Reinforcement” and “Increased Motivation” increase, “Continuing Behavior” ensues; subjective well-being was enhanced and resulted in a decrease in experiential avoidance. In the future, the questionnaire’s efficiency should be confirmed by conducting surveys with different participants, for instance, clinical patients, and a broader range of age groups and, subsequently, demonstrating its reliability and validity.
