Summary

This trial tests whether a phone-based positive psychology program can improve mood, quality of life, and daily functioning in adults who have just undergone a stem cell transplant for blood cancer. Participants receive weekly calls and complete exercises focused on gratitude, personal strengths, and meaning over eight weeks. The study aims to see if this approach is feasible and acceptable, and whether it may help patients feel better emotionally during recovery.

Active substance: A phone-based positive psychology intervention involving weekly calls and exercises focused on gratitude, strengths, and meaning over 8 weeks.
What this could lead to: If effective, this could offer a simple, non-drug way to boost emotional well-being and quality of life for patients recovering from stem cell transplants.
What could go wrong: This is a small early-stage proof-of-concept study, so results may not apply broadly. The intervention's benefits are uncertain and depend on patient engagement.
