Can we identify "at-risk" children and adolescents for poor transplant outcomes in the psychosocial evaluation before solid organ transplantation? The reliability and validity study of Pediatric Transplant Rating Instrument (P-TRI) in Turkish pediatric renal transplant patients

BackgroundThis study aims to translate the Pediatric Transplant Rating Instrument (P-TRI) to conduct a validity and reliability study on Turkish children and define a cutoff value of this scale. MethodA total of 151 pediatric kidney transplant patients were included in the study. The files of the patients were reviewed by two clinicians, and the scale was filled for inter-rater reliability. One of the clinicians filled the scale again after one month for intra-rater reliability. Glomerular filtration rate (GFR) and creatinine values were used for predictive validity. A GFR below Correlation of P-TRI with GFR (r = .252, p = .003) and creatinine (r = -.249, p = .002) was performed, and the internal consistency of the scale items as measured by Cronbach's alpha coefficient was found to be 0.825. When the test was performed again, the intra-class correlation coefficient was found as .922 for intra-rater reliability and as .798 for inter-rater reliability. For both creatinine and GFR, the best cutoff point for the total score was found to be 66.5. ConclusionsPatients who received P-TRI above 66.5 could be at risk in the post-transplant period. Identification of these patients before transplantation and following these young people more closely will aid in the prevention of serious consequences. The reliability and validity scores are satisfactory for use in transplantation clinics for psychosocial evaluation and compliance in Turkish pediatric renal transplantation patients.
