title: [Factors Influencing Changes in Quality of Life in Patients undergoing Hematopoietic Stem Cell Transplantation: A Longitudinal and Multilevel Analysis].
abstract: OBJECTIVE
  This study was a prospective longitudinal study to identify changes in quality of life in patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT). It was based on Roy's adaptation model.
  
  
  METHODS
  The questionnaires were administered before HSCT, 30 and 100 days after HSCT. Of the 48 potentially eligible patients, 44 (91.7%) participated in the study and 40 (90.9%) completed the questionnaires at 100 days after HSCT. Multilevel analysis was applied to analyze changes in quality of life.
  
  
  RESULTS
  Overall, quality of life showed a decreasing tendency from pre-HSCT to 100 days after HSCT. The adaptation level of participants was compensatory. Type of conditioning was the significant factor influencing quality of life before HSCT (β₀₀=79.92, p<.001; β₀₁=-12.64, p<.001) and the change rate of quality of life (β₁₀=-1.66, p=.020; β₁₁=2.88, p=.014). Symptom severity (β₂₀=-1.81, p=.004), depression (β₃₀=-0.58, p=.001), social dependency (β₄₀=-0.35, p=.165), and loneliness (β₅₀=-0.23, p=.065) had a negative effect on changes in quality of life. Symptom severity and depression were statistically significant factors influencing changes in quality of life.
  
  
  CONCLUSIONS
  According to the results of this study, the development of nursing intervention is needed to improve quality of life in patients undergoing allogeneic hematopoietic stem cell transplantation in the early immune reconstruction period. The interventions should include programs to enhance coping capacity and programs to help control symptom severity and depression. Also these interventions need to be started from the beginning of HSCT and a multidisciplinary approach would be helpful.
