Translation and validation of a lifestyle questionnaire related to prostate cancer.

BACKGROUND: Valid and reliable instruments are needed to measure prostate cancer-related lifestyle changes, plan evidence-based interventions to modify lifestyle, and improve treatment outcomes. Due to the lack of appropriate instruments, this study was conducted to translate the Effects of Prostate Cancer upon Lifestyle Questionnaire (EPCLQ) into Persian and examine its psychometric properties in a sample of Iranian older adults with prostate cancer. METHODS: This methodological study was carried out between 2021 and 2022. Initially, the EPCLQ, comprising 36 items, was translated into Persian through a meticulous translation and back-translation procedure. Subsequent steps involved the assessment of face validity, qualitative content validity, content validity index, content validity ratio, construct validity via confirmatory factor analysis, and reliability testing of the Persian version of the EPCLQ. RESULTS: The psychometric evaluation led to the exclusion of 4 items from the EPCLQ. The refined model demonstrated satisfactory fit indices (PCFI = 0.732, PNFI = 0.696, CMIN/DF = 2.29, RMSEA = 0.072, IFI = 0.920, CFI = 0.919, and GFI = 0.971), indicating an appropriate fit of the final model. The internal consistency, as measured by Cronbach's alpha, was 0.67, and the intraclass correlation coefficient for the questionnaire was 0.938, reflecting high reliability. CONCLUSIONS: The Persian version of the EPCLQ, now consisting of 32 items, has been validated and is reliable for assessing the impact of prostate cancer on lifestyle among older adults. Its simplicity and the clarity of the items make it suitable for use in clinical settings or during home visits for follow-up assessments.

Comparison of Retinopathy of Prematurity Incidence in Preterm Infants of Mothers with Preeclampsia and Infants of Healthy Mothers.

Introduction: Preeclampsia is one of the four leading causes for pregnancy complications, maternal-fetal and neonatal mortality. This study was aimed at comparing the incidence of retinopathy of prematurity in neonates of mothers with preeclampsia and neonates of healthy mothers. Methods: This cross-sectional study was performed among 213 mothers, including 49 healthy mothers and 164 mothers with preeclampsia whose neonates were admitted to the neonatal intensive care unit of Ghaem Hospital, Mashhad, Iran, during 2016-2021. The participants were chosen using the convenience sampling method. The data collection tool was a researcher-made checklist including items on laboratory evaluation, maternal and neonatal characteristics, and eye examination. The data were analyzed using t-test and Chi-square. Results: In the two groups, gestational age (P = 0.112), first-minute Apgar score (P = 0.209), and fifth-minute Apgar score (P = 0.949) were not significantly different. There was a significant difference between the two groups in terms of maternal age (P = 0.0001), type of delivery (P = 0.0001), premature rupture of membranes (P = 0.003), and eye condition (P = 0.033). Conclusion: The results of our study show that preeclampsia affects the prognosis of infants, and in neonates with preeclamptic mothers, the rate of premature rupture of the membranes, cesarean delivery, and retinopathy of prematurity were higher.
