Study summary

Identify the psychological factors (i.e. personality and transactional factors), beneficial and deleterious, at different phases of the transplant process, on the patient's mental health (quality of life, short and long-term post-transplant recovery) and physical health (e.g. infections, relapse, length of hospitalization or even death).

Read the detailed description

To reach the research purposes, questionnaires will be given to patients at different times during the transplant process :

  1. Pre-admission transplant questionnaire: given and collected by the transplant physician during the pre-graft consultation before entering hospitalization (approximatively 15 days before). To be completed by the patient on site (approximately 45 minutes to complete the questionnaire)
  2. Transplant admission questionnaire: given during the first days of hospitalization. To be completed within 6 days and returned to the transplant physician (approximately 30 minutes to complete the questionnaire)
  3. Post-transplant follow-up questionnaire: given in consultation at 6 months by the transplant physician (between 30 and 45 minutes to complete the questionnaire in consultation)

The questionnaires include validated and standardized scales.

The first questionnaire contains scales on dispositional factors (i.e. personality factors) . The second one is on the so-called transactional adjustment factors. And the third is on post-transplant factors (e. g. post-traumatic growth). Scales from the first and second questionnaire will be used to obtain a longitudinal view.

The study population concerns all patients going to receive an allograft transplantation, aged over 18 years, who have consented to answer the various questionnaires over a period of approximately 7 months . The participants come from the hematology departments of the Saint-Louis Hospital in Paris, the Estaing University Hospital in Clermont-Ferrand and the Brabois Hospital in Nancy.

Ran from Nov 2017 to primary completion in Feb 2020, 27 months.

Of 103 non-industry interventional studies with no phase under Leukemia, half reached primary completion within 38 months of starting (the median), counting those still running; a quarter within 22 and three quarters within 128. This study's 27 months is below that.

Counting every sponsor, half of 110 studies reached it within 38 months; a quarter within 22 and three quarters within 75.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 22, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
