Background: This 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.Method: A 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 <60 ml/min/1.73 m 2 and creatinine up to 3.0 mg/ dl was defined as risk factors.Results: 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. Conclusions:Patients who received P-TRI above 66.5 could be at risk in the posttransplant 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.

Background. Electronic media have become an important element in the lives of modern children. Devices like televisions, smartphones and tablets are widely used by some parents in order to manage hyperactive, stubborn and impulsive children who need high-intensity stimuli. Consequently, a child`s temperament and parental attitudes affect the duration and frequency of 3-7-year-old children`s screen (television-smartphone-internet) use. Based on this information, the objective of the present study was to evaluate the relation between screen media exposure, the child`s temperament and parental attitudes in 3-7-year-old children. Methods. The participants of this study were 210 children of 3 to 7 years of age. Rothbart`s Child Behavior List was used to assess temperament; the Parenting Attitude Research Instrument was used to determine the parental attitudes. Screen media exposure assessment questionnaire, which included questions about the age the child started using the TV, smartphone and/or internet, and the duration of their daily usage, were filled in with the children`s parents. Results. It was found that the increase in activity level, approach and discomfort was negatively correlated to the age the child started watching television, while shyness was positively related to the same phenomenon. The scores of the discomfort temperament subscale had a direct relation to the duration of watching television. Background television is negatively related to attention, inhibitory control, and perceptual sensitivity. Dependency, marital conflict and strictness and authoritarianism parameters were found to be positively related to the duration of playing with a smartphone. Also, in this study we found that negative temperament characteristics adversely affected screen media exposure and poor parenting styles worsen this relationship. Conclusions. Both temperament and parenting styles affect screen media exposure. In addition, it was understood that parenting styles also affect the relation between temperament and screen exposure. Parental information programs on this subject can eliminate the lack of information related to early screen media exposure in preschool children.
