“…We used univariate linear regression models to explore factors associated with patients’ perceptions of PC (main outcome of interest). Predictors of interest were identified a priori by the research team 20 , 25 , 26 , 27 and included demographic factors (age, sex, race, ethnicity, importance of spirituality, marital status, education), clinical factors (transplant type, Karnofsky performance status, hematopoietic cell transplant-comorbidity index, disease risk, and presence and severity of graft-versus-host disease), time since transplant, transplant center, region of transplant center, familiarity with PC, knowledge of PC, perceived knowledge of PC, perceptions of PC, unmet PC needs, patient’s belief they will be cured with the transplant, symptom burden, and quality of life (physical and mental health). We assessed for collinearity between predictors using Pearson correlation coefficients and found positive collinearity between knowledge of PC (13-item survey) and perceived knowledge about PC (1 item in familiarity with PC domain) (r = .67, P < .0001).…”
