“Sense-making” has been proposed as a perspective through which to understand clients’ cognitive changes in cognitive therapy. Until now, sense-making has been measured through subjective verbal reports; however, we considered it important to measure sense-making through nonverbal responses. In the present study, we developed a checklist of nonverbal responses that were thought to indicate “sense-making” and examined whether checklist scores predicted behavioral change. In Study 1, the checklist items were scrutinized through a survey of clinical psychologists. In Study 2, we examined whether the checklist predicted behavioral change. The results showed that the checklist did in fact predict behavioral changes. The results showed that the checklist predicted behavioral changes. The present study provided a valid non-verbal indicator of “sense-making”, but further investigation of the detailed checklist items and its clinical application is warranted in future research.
