“…The alpha coefficients suggest that the ThyPROro (85-item) and ThyPROro-39 are reliable instruments for evaluating QoL of patients with benign thyroid diseases. The values of Cronbach`s alpha in our study, being in the range 0.78-0.93 for the ThyPROro (85-item) and 0.78-0.87 for the ThyPROro-39, were comparable to previous findings (12,39). Watt et al reported a Cronbach`s alpha above 0.9, a very high reliability estimate, from 904 respondents (12).…”

Background. ThyPRO is a recently developed thyroid-specific quality of life (QoL) questionnaire applicable to patients with benign thyroid disorders(BTD). The aim of the present study was to translate ThyPRO and ThyPRO-39 into Romanian, and to evaluate reliability and cross-cultural validity.Methods. Standard methodology for translation and linguistic validation of patient-reported outcomes (PRO) was applied. The questionnaire was completed by 130 patients with benign thyroid diseases seen at Department of Endocrinology in the Emergency County Hospital, Tîrgu Mureș, Romania, between October 2015 and March 2016. Internal reliability of the Romanian version of the ThyPRO (ThyPROro) scales was assessed for multi-item scales using Cronbach's alpha coefficient. An efficient method for testing cross-cultural validity is analysis of differential item functioning (DIF). Uniform DIF between the Romanian and the original Danish sample was investigated using ordinal logistic regression. The translation process proceeded without difficulties, and any disagreements were revised by one of the developers and the language coordinator.Results. Internal reliability for ThyPRO was satisfactory. Cronbach`s alpha coefficients for the 13 scales ranged from 0.78 to 0.93 for the ThyPROro and 0.78 to 0.87 for the ThyPROro-39. In the 85-item ThyPRO, nine instances of DIF were found. Most were minor, explaining <3% of the variation in scale score, but DIF in positively worded items were larger, with explained variance (R2's) around 10-15%. Conclusion.The ThyPROro questionnaire is ready for assessment of health-related quality of life in Romanian patients with benign thyroid diseases.

“…One study using a Romanian version of the ThyPRO 30 found that the Cronbach α coefficients ranged from 0.78 to 0.93, and another using a Serbian version found that they ranged from 0.83 to 0.95. 31 There was no standard cut-point on the acceptable value of Cronbach α coefficients. However, the acceptable values in most reports were ranging from 0.70 to 0.95.…”

Introduction The Thyroid-Related Patient-Reported Outcome (ThyPRO) is a new thyroid-specific quality of life patient-reported outcome measure for benign thyroid disorders. Objective The objective of this study was to investigate the face validity, internal consistency, and test-retest reliability of the Thai version of the ThyPRO (ThyPROth). Methods The translation of the ThyPRO questionnaire was performed using double forward translation, reconciliation, single backward translation, and cognitive debriefing, followed by a panel review. Five thyroid patients evaluated the face validity. The internal consistency and test-retest reliability were evaluated in 30 patients with thyroid diseases. Results The overall validity score was 3.75 (range 0–4). The Cronbach α coefficient ranged from 0.76 to 0.95, with a total coefficient of 0.97 (95% CI 0.962–0.959), indicating excellent internal consistency. The test-retest reliability coefficient ranged from 0.70 to 0.97. All values were 0.70 and above. The total reliability coefficient was 0.86 (95% CI 0.724–0.932), indicating excellent reliability. Conclusion The ThyPROth was found to be valid and to exhibit good internal consistency and test-retest reliability. The questionnaire is ready for implementation in the assessment of health-related quality of life in Thai patients with benign thyroid diseases.

“…Like the original questionnaire 9 and other translated versions 29 , the ThyPROes demonstrated good quality measurement using classic procedures for reliability assessment. Additionally, following the methodology used for cross-cultural validation of other language versions 25 , we also evaluated DIF between the Spanish translated version and the Danish master questionnaire to investigate potential language bias.…”
