Predictors of parental distress during acute phase of pediatric hematopoietic stem cell transplantation in Japan: A multicenter prospective study

OBJECTIVE: The purposes of this study were (1) to describe the levels of anxiety and depressive symptoms in parents of children undergoing hematopoietic stem cell transplantation (HSCT) before (Time 1 [T1]) and one month after transplantation (Time 2 [T2]), and (2) to identify the pre-HSCT factors that predict anxiety and depressive symptoms in fathers and mothers one month after transplantation. METHODS: A prospective quantitative study was conducted at four children's hospitals between June 2015 and September 2016 using self-administered questionnaires and medical records. Parents from 23 families, including 19 fathers and 23 mothers, completed the Hospital Anxiety and Depression Scale (cutoff score: 8) and provided information regarding their stress appraisal, coping strategies, family functioning, demographic characteristics, and children's health-related quality of life. Hierarchical multiple regression analysis was performed to identify the variables that predicted T2 paternal and maternal anxiety and depressive symptoms. RESULTS: Among the parents, 15 fathers (79%) and 11 mothers (48%) reported anxiety symptoms, and 13 fathers (68%) and 9 mothers (39%) reported depressive symptoms above the cutoff level for clinical relevance at T1. Similarly, 11 fathers (58%) and 6 mothers (26%) reported anxiety symptoms, and 10 fathers (53%) and 9 mothers (39%) reported depressive symptoms above the cutoff level at T2. Overall, parents' anxiety and depressive symptoms did not differ significantly between T1 and T2. For fathers, both T1 depressive symptoms and the understanding of their children's medical situation through communication with other parents and consultation with medical staff predicted T2 paternal depressive symptoms. For mothers, T1 maternal anxiety symptoms and marital satisfaction predicted T2 anxiety symptoms. CONCLUSIONS: The medical staff should understand that parents of children undergoing HSCT experience considerable psychological distress throughout the treatment process, and therefore, they should adopt unique approaches to reduce such distress.
