The Effect of Theraplay on Prolonged Grief and Post-Traumatic Stress Disorder in Bereaved Siblings of Children with Cancer: A Preliminary Study

 Death of any of siblings is an overwhelming, severe, and prolonged challenge in children development process and is a major risk factor for psychiatric disorders in childhood and later. Interventions for bereaved families following a child’s death have been examined over the last several decades. However, no effective treatment for bereavement siblings prolonged grief disorder (PGD) and post-traumatic stress disorder (PTSD) has been found yet.

 The study aimed at determining the effect of Theraplay on the symptoms of prolonged grief (PG) and post-traumatic stress disorder (PTSD) in siblings of a deceased child with cancer.

 In this preliminary study, a multiple baseline single-subject design with a follow-up period was used. The statistical population included siblings and mothers of children aged 6-10 years who had been under treatment at Mahak Child Cancer Hospital and died 1or 2 years ago. From this population, 4 mother-child pairs were selected as the study sample by convenience sampling. Each mother-child pair participated in 15 Theraplay sessions once a week (45-minute section). Assessments were performed using the inventory of prolonged grief for children (IPG-C) and the University of California at Los Angeles Posttraumatic Stress disorder reaction index for DSM-5 (UCLA PTSD-RI) at baseline, intervention sessions and follow-up stages. Visual analysis of graphic displays of level, reliable change index (RCI) and clinical significance were used to analyze the data. Data analysis and drawing graphs were performed in Microsoft Excel 2016.

 Results of visual and quantitative analysis of data showed that PG symptoms decreased in all 4 participants during the treatment and follow-up. Also, according to the results, Theraplay intervention significantly reduced PTSD in all participants.

 Theraplay appears to be effective in reducing PG and PTSD in bereaved siblings. However, the reduction rate varied in different subjects. According to the findings, Theraplay helped subjects accept grief and loss and this method can be used to help the mental health of other bereaved children.
