A two-part, qualitative descriptive design will be employed to systematically adapt the Coping Together manuals based on recommendations of HSCT patients, CGs, dyads and clinicians (for Phase 1 only). For this study, CG is defined as spouse, partner, family member, friend, colleague, or neighbor who can, but do not necessarily live together, and provide uncompensated care. A dyad is defined as a combination of a patient and their designated CG. Dyads can review the Coping Together manuals individually or jointly, but will be interviewed together.
