Participants recruited from the Dana-Farber Cancer Institute, Moffitt Cancer Center, and Fred Hutchinson Cancer Center who are randomized to the intervention/experimental arm will receive the STEPP intervention, which pairs patients preparing for their transplant hospitalization with hematopoietic stem cell transplantation (HSCT) survivors for informational, emotional, and practical support. Participants will complete questionnaires (in person, over the computer or telephone, or by mail) at predetermined days per protocol.
Participants recruited from the Dana-Farber Cancer Institute, Moffitt Cancer Center, and Fred Hutchinson Cancer Center who are randomized to the minimally enhanced usual care control arm will receive standard psychosocial care provided by social work plus a comprehensive list of local, regional, and national peer support resources. Participants will complete questionnaires (in person, via computer or telephone, or by mail) at predetermined days per protocol.
STEPP, a phone-delivered structured peer support intervention for patients preparing to undergo hematopoietic stem cell transplantation (HSCT), consists of five sessions which integrates evidence-based strategies from cognitive-behavioral therapy, mindfulness, and positive psychology with informational, emotional, and practical support. STEPP is manualized and delivered by an HSCT survivor who is trained and supervised by a clinical psychologist.
