| Introduction: Complicated grief (CG) exhibits distinct characteristics compared to natural grief, adversely affecting the physical and mental health of bereaved individuals. Therefore, it is essential to mitigate and treat these complications through various psychotherapeutic interventions. This study aimed to compare the effectiveness of Complicated Grief Therapy (CGT) and Acceptance and Commitment Therapy (ACT) on blood pressure and complex grief symptoms among suicide survivors. Methods: A quasi-experimental study with a pretest-posttest design and a control group was conducted in 2024. The statistical population included suicide survivors with complex grief symptoms in Kerman, Iran, selected via census sampling. The sample comprised 30 participants divided into three groups (two experimental groups and one control group, each with 10 individuals). One experimental group received ACT, while the other underwent CGT; the control group received no intervention. A follow-up phase was conducted after two months. Data were analyzed using SPSS version 23. Results: In both experimental groups, most participants exhibited diastolic blood pressure below 90 mmHg and systolic blood pressure below 140 mmHg. In contrast, the control group predominantly showed diastolic blood pressure above 90 mmHg and systolic blood pressure exceeding 140 mmHg. Additionally, the mean scores of complex grief symptoms significantly decreased in the experimental groups compared to the control group. The effect size of CGT on grief symptoms was 78% (p<0.001), while ACT showed a 72% (p<0.05). Conclusion: The findings indicate that both therapeutic approaches effectively reduced blood pressure and complex grief symptoms in suicide survivors, with Complicated Grief Therapy demonstrating superior efficacy. |
