This study examined the effectiveness of dialectical behavior therapy intervention on emotion regulation and death anxiety in old women. This quasi-experimental study was conducted using a pretest-posttest design with a control group. The research population included elderly women aged 60-75 years who were members of the Tehran Municipality Retirees Association in 2020. A total of 30 women were assigned to intervention and control groups (15 persons in each group). The participants in the intervention group received the dialectical behavior therapy (DBT) intervention for 10 sessions while the participants in the control group did not receive any intervention. The results of the analysis of covariance (ANCOVA) showed that there was a significant difference between the women in the intervention and control groups in terms of cognitive emotion regulation and death anxiety on the posttest. This therapy can be used for the elderly living in nursing homes and aging associations and institutions.
