Abstract

Background and Objectives: Traumatic brain injury (TBI) is one of the main causes of disability.

Forty caregivers of TBI patients who referred to Kashan's Shahid Beheshti Hospital, Iran, since 2017 until 2019 were randomly assigned to the experimental (n = 20) and the waiting list control (n = 20) groups. Both the groups completed a demographic information questionnaire, the Family Assessment Device, the Experiential Avoidance in Caregiving Questionnaire, and the anxiety subscale of the Depression, Anxiety, and Stress Scale in pretest, posttest, 3-month follow-up, and 6-month follow-up. Results: The results of repeated measures analysis of variance showed that ACT program can significantly decrease the anxiety, experiential avoidance, and most of the dimensions of the family functions (P < 0.005). Conclusion: ACT could be utilized to improve the family functions and reduce the experiential avoidance and the anxiety of the TBI patients' caregivers.
