Improving Quality of Life in Hematopoietic Stem Cell Transplantation Survivors Through a Positive Psychology Intervention.

Abstract

Despite advances in transplantation medicine, psychological distress and quality of life and functional deficits continue to compromise survivorship after hematopoietic stem cell transplantation (HSCT). With increasing numbers of HSCT survivors, supportive oncology interventions that target health-related outcomes in HSCT survivorship are needed. Here we aimed to test the feasibility and acceptability of a group format phone-delivered positive psychology (PP) intervention in HSCT survivors. This is a one-arm pilot study design that adapted and tested an individual PP intervention used in cardiac disease to a phone-delivered group-based program for HSCT survivors who were .4 to 39 years post-transplantation. All participants received an 8-session weekly PP intervention. We assessed feasibility by the enrollment and intervention completion rates. We examined acceptability on a 10-point Likert scale of ease and utility. Unstructured qualitative interviews were used to obtain participant feedback on the intervention for future application in a larger trial. Self-reported assessments on psychological, functional, and quality of life outcomes were administered at baseline and at follow-up (the end of the intervention). Of 64 eligible participants, 29 (45%) enrolled in the study. For the main aim of intervention feasibility and acceptability, participants completed 96% of all PP sessions and rated the ease (7.6 ± 1.7) and utility (8.1 ± 1.1) of sessions highly. Of the self-reported assessments obtained, the PP intervention resulted in improvements in the resilience scale (mean difference, 2.4 ± 5.4; P=.03). From unstructured qualitative interviews, participants reported the PP exercises and intervention helped them to focus on positive emotions and the group format fostered a sense of community and social support. An 8-week phone-delivered group format PP intervention is feasible and acceptable in HSCT survivors. The piloted intervention could be tested with minor modifications in a randomized study to definitively examine the impact of the group format PP intervention on health-related outcomes.
