The Efficacy of Time Perspective Therapy in Reducing Symptoms of Post-traumatic Stress, Anxiety, and Depression in Females with Breast Cancer

Abstract

Background: Breast cancer is the biggest risk factor that endangers women's health. It is considered the highest stress-causing disease due to the unpleasant effects of disease on different aspects of patients’ life. Breast cancer is commonly associated with the symptoms of post-traumatic stress and its comorbidities such as anxiety and depression. It appears that time perspective therapy (TPT), as a new psychological treatment, can reduce the symptoms of post-traumatic stress, anxiety, and depression in females with breast cancer. Methods: This is a randomized controlled trial conducted from February to September 2019. A total of 30 patients with breast cancer were selected through a convenience sampling technique and were randomly divided into the control and treatment groups. The latter group attended 6-week sessions (each session lasted 90 minutes long) to receive TPT. To conduct pretest and posttest, all participants in the two groups were asked to fill out the following questionnaires: (1) Zimbardo Time Perspective Inventory (ZTPI); (2) The Post-traumatic Stress Disorder Checklist (PCL); (3) Beck Anxiety Inventory (BAI); and (4) the second version of Beck Depression Inventory (BDI-II). The analysis of covariance (ANCOVA) was used to evaluate the effects of treatment. A P-value smaller than 0.05 was considered significant. Results: Data analysis of 28 patients from the experimental and control groups showed that TPT significantly reduced the symptoms of post-traumatic stress, anxiety, and depression in the treatment group (P < 0.001 for symptoms of post-traumatic stress and anxiety, and P = 0.002 for depression). Such a difference was not seen in the control group. Conclusions: TPT may be an effective approach to reduce symptoms of post-traumatic stress, anxiety, and depression in Iranian women with breast cancer. Further investigations are required to confirm these findings, which may in turn help heath care professionals use TPT to promote the mental health of females with breast cancer.
