Greater Social Isolation and Social Constraints Prior to Hematopoietic Stem Cell Transplant Are Associated with Greater Anxiety and Depressive Symptoms

Hematopoietic stem cell transplantation (hereafter “HCT”) is a physically and psychologically difficult treatment for patients with hematological cancers. This study examined relationships among patients’ reports of pre-transplant social isolation, social constraints, and psychological distress. We used baseline data from a multisite randomized controlled trial evaluating the effects of expressive helping writing to reduce physical and emotional symptoms in HCT patients. We collected data prior to randomization and before either allogenic or autologous HCT using validated scales to assess social constraints, social isolation, anxiety, and depressive symptoms. We analyzed data using bivariate analysis and multivariate linear regression. We also explored whether social isolation mediated the effect of social constraints on both of our outcomes: anxiety and depressive symptoms. Among 259 adults recruited prior to transplant, 43.6
