Objective: This study aimed to test the reliability and validity of the Turkish version of the Parents’ Postoperative Pain Measure. Materials and Methods: The permission was obtained via email from the creator of the measure, Christine T. Chambers. A sample of 150 children aged 7–12 years (48.7% girls, 51.3% boys) was recruited for this methodological study. The instrument consisted of 15 items. A “Sociodemographic Questionnaire, ” the “Parents’ Postoperative Pain Measure, ” and the “Wong–Baker Faces Pain Rating Scale” were utilized as data collection instruments. The study consisted of language and content validity testing (the technique of translation-back translation, Lawshe’s technique), construct validity (exploratory and confirmatory factor analyses), and reliability testing (Kuder–Richardson 20 test, Pearson product moment correlation between parallel forms). Measurements were taken on postoperative days 1, 2, and 3. Results: The results of the factor analysis for validity demonstrated acceptable levels. The factor analysis produced a single factor with a total variance of 69%. The Parents’ Postoperative Pain Measure and the Wong–Baker Faces Pain Rating Scale exhibited positive correlations on postop days 1, 2, and 3 (r=0.67/p<0.01, r=0.74/p<0.05, r=0.79/p<0.05). The internal consistency coefficient (Kuder–Richardson 20) was 0.851. Conclusion: The Parents’ Postoperative Pain Measure, originally developed by Chambers et al. in the English language, is a valid and reliable instrument that is suitable for use in Turkish and the Turkish culture.
