 The proposed project is a pilot randomized control trial of the Pep-Pal Psychoeducation and Skills Based Intervention versus a treatment as usual control group. A total of 120 caregivers; 40 caregivers of patients with HSCT Hematopoietic Stem Cell Transplantation, 40 caregivers of patients enrolled in phase I oncology trials, and 40 caregivers of patients with advanced cancer Stage IV, solid tumor will be enrolled in this study. The investigators do not expect different outcomes from these three groups, rather these populations are selected to optimize recruitment within a short time frame. The caregivers will be randomized to either treatment as usual or Pep-Pal intervention.
