Meaning-Centered Psychotherapy for Addressing Existential Distress of Patient/Caregiver Dyads Following Hematopoietic Stem Cell Transplantation: Feasibility and Acceptability

10 août 2026 mis à jour par: Natalie S. McAndrew, PhD, RN, Mayo Clinic
The purpose of this study is to learn whether Meaning-Centered Psychotherapy (MCP-Dyad) is practical, acceptable, and helpful to survivors and caregivers during recovery after stem cell transplant. MCP-Dyad is a meaning-focused support program. It is designed to help people stay connected to meaning, cope with difficult experiences, and communicate as a pair during recovery.

Mesures de résultats secondaires

Mesure des résultats
Description de la mesure
Délai
Change in Benefit Finding Scale (BFS) score
Délai: Baseline, End of treatment (approximately 14 weeks), 8 weeks post-intervention
The impact of MCP-Dyad on benefit finding will be measured using a slightly modified version of the Benefit Finding Scale (BFS), a 17-item measure that captures positive life challenges resulting from adversity (e.g., personal priorities, acceptance, daily activities, family, world views, relationship, purpose). Higher scores indicate greater benefit finding.
Baseline, End of treatment (approximately 14 weeks), 8 weeks post-intervention
Change in Communal Coping Domains score
Délai: 8 weeks post-intervention
The Communal Coping Domains instrument assesses how patients and caregivers manage health-related behavior change, particularly in the context of health threats by measuring shared perceptions, confidence, and behaviors. There are three tailored subscales: use of communal coping (how frequently dyads use joint efforts to manage health threats), how confident the dyad is in working together to manage health, and beliefs about communal coping strategies. Responses for the use of the communal coping domain range from 1(never) to 5 (very often), and responses for the couple efficacy and outcome efficacy range from 0 (not at all) to 10 (very much). Higher overall scores indicate greater confidence in patient/caregiver coping strategies.
8 weeks post-intervention
Change in survivor and caregiver health-related quality of life.
Délai: Baseline, End of treatment (approximately 14 weeks), 8 weeks post-intervention
The impact of MCP-Dyad on patient and caregiver health-related quality of life will be assessed using the Functional Assessment of Cancer Therapy -Bone Marrow Transplant (FACT-BMT). The patient instrument is a multidimensional measure of quality of life in adult HSCT patients. Each item is rated from 0 (not at all) to 4 (very much) and is an assessment of symptoms over the past 7 days. Domains include social and family well-being, emotional well-being, functional well-being, and BMT-specific concerns. Higher scores overall indicate better quality of life.
Baseline, End of treatment (approximately 14 weeks), 8 weeks post-intervention
Change in survivor and caregiver existential distress
Délai: Baseline, End of treatment (approximately 14 weeks), 8 weeks post-intervention
The impact of MCP-Dyad on the patient and caregiver's meaning and purpose (increased meaning and purpose equivalent to less existential distress) will be measured using the 48-item Life Attitude Profile-Revised (LAP-R) instrument. It has six domains (purpose, coherence, life control, death acceptance, existential vacuum, goal seeking) that make up two subscales, the Personal Meaning Index and Existential Transcendence. Higher scores generally indicate a more positive attitude towards life.
Baseline, End of treatment (approximately 14 weeks), 8 weeks post-intervention
Change in survivor and caregiver spiritual well-being
Délai: Baseline, End of treatment (approximately 14 weeks), 8 weeks post-intervention
The impact of MCP-Dyad on the patient's and caregiver's spiritual well-being will be measured using the Functional Assessment of Chronic Illness Therapy Spiritual Well-being (FACIT-Sp) Scale. It has two subscales, one for faith and another for meaning/peace. Higher scores indicate greater spiritual well-being.
Baseline, End of treatment (approximately 14 weeks), 8 weeks post-intervention
Change in survivor and caregiver mutuality (quality of relationship)
Délai: Baseline, End of treatment (approximately 14 weeks), 8 weeks post-intervention
The impact of MCP-Dyad on survivor and caregiver mutuality will be measured using Mutuality Scale (MS). The Mutuality Scale measures the positive quality of the relationship between the care recipient and the caregiver. Grounded in the concept of mutuality (degree of love, reciprocity, shared pleasurable activities, and shared values) in the patient/caregiver relationship. There is a four-domain structure with items rated from 0 (not at all) to 4 (a great deal) with question stems examining varies aspects of the relationship (e.g., how much do you enjoy spending time together). Higher overall scores indicate greater mutuality.
Baseline, End of treatment (approximately 14 weeks), 8 weeks post-intervention
Change in dyadic adjustment (couples only)
Délai: Baseline, End of treatment (approximately 14 weeks), 8 weeks post-intervention
The impact of MCP-Dyad in couples will be measured using the Revised Dyadic Adjustment Scale (RDAS). The RDAS is a self-report measure of relationship quality in couples. It assesses dyadic consensus, dyadic satisfaction, and dyadic cohesion to give an overall index of marital quality. The rating scale is 0 (always disagree) to 5 (always agree). Higher overall scores indicates greater relationship satisfaction.
Baseline, End of treatment (approximately 14 weeks), 8 weeks post-intervention
Change in illness-related communication
Délai: Baseline, End of treatment (approximately 14 weeks), 8 weeks post-intervention
The change in illness-related communication will be measured using the Social Constraints Scale. This scale measures the extent to which individuals perceive their social environment, particularly close relationships, as a limiting or discouraging their ability to express thoughts and feelings related to a stressful experience. Items are rated from 1(never) to 4 (very often). Higher scores are equivalent to more social constraints in the relationship.
Baseline, End of treatment (approximately 14 weeks), 8 weeks post-intervention
Change in survivor and caregiver needs/distress
Délai: Baseline, End of treatment (approximately 14 weeks), 8 weeks post-intervention
The impact of MCP-Dyad on the survivor and caregiver's needs/distress will be measured using the Cancer SupportSource Survivors: CCS-15+ and the CancerSupportSource-Caregiver: CCS-Caregiver-18+ instruments. Survivors and caregivers will rate their level of concern from 0 (not at all) to 4 (very serious concern). Questions for survivors focus on emotional well-being, symptom burden & impact, body image & healthy lifestyle, health care team communication, relationships & intimacy. Questions for caregivers focus on 5 areas of concern (emotional well-being, survivor well-being, caregiving tasks, finances, and healthy lifestyle) and areas of desired support. A total score for distress is recommended based on 18 items.
Baseline, End of treatment (approximately 14 weeks), 8 weeks post-intervention
Change in survivor and caregiver psychological distress
Délai: Baseline, End of treatment (approximately 14 weeks), 8 weeks post-intervention
The impact of MCP-Dyad on psychological distress will be measured using 2 anxiety and 2 depression questions from the CCS-15+ and the CCS-Caregiver-18+. These questions have established clinical cut offs. Scores range from 0 to 8. Survivor scores of 3 or above signify clinically significant anxiety or depression. Caregiver anxiety scores of 4 and above, and depression scores of 3 or above, indicate clinically significant distress.
Baseline, End of treatment (approximately 14 weeks), 8 weeks post-intervention
Change in Dyadic Relationship Scale score
Délai: Baseline, End of treatment (approximately 14 weeks), 8 weeks post-intervention
The Dyadic Relationship Scale is a brief dyadic measure assessing positive dyadic interaction and negative dyadic strain from both caregiver and care recipient perspectives. The caregiver version includes 11 items and the care recipient version includes 10 items, with two subscales: positive dyadic interaction and negative dyadic strain.
Baseline, End of treatment (approximately 14 weeks), 8 weeks post-intervention
Change in interdependence of survivor and caregiver
Délai: Baseline, End of treatment (approximately 14 weeks), 8 weeks post-intervention
The Inclusion of Other in the Self Scale is a single-item pictorial measure of perceived relationship closeness and self-other overlap. Respondents select one of seven increasingly overlapping circle pairs to represent their relationship with a specified other person, with higher scores indicating greater perceived closeness.
