Introduction: There are different instruments that measure quality of life related to oral health in children, such as the CPQ, which has two versions (CPQ8-10 and CPQ11-14). Objective: The purpose of this study was to cross-culturally adapt the Peruvian version of CPQ11-14 to the language of the Colombian Caribbean, determine the psychometric properties of reproducibility, and describe the usefulness of the CPQ11-14 questionnaire. Materials and methods: With a sample of 214 participants, in this quantitative observational psychometric scale evaluation study, measurements of reliability, internal consistency, and discriminant power of the CPQ11-14 were performed. The structure of the instrument was explored by Exploratory Factor Analysis (EFA). With factor extraction via the Principal Axis Method with Varimax rotation. Results: A global Cronbach's alpha of 0.9 was obtained. For the EFA, the measure of sampling adequacy was evaluated with the KMO test = 0.829 (p = 0.001), and the mean adequacy of the sample with the Bartlett test = 2904.538 (p = 0.001). These values allowed for the calculation of factor loadings to justify each item in the dimensions of the scale. Conclusions: This version of the instrument showed an adequate response to reproducibility, however, the low percentages of success in the discriminant power and some null factor loadings in some items suggest changes in the wording and a new evaluation to study their behavior. However, this version of the instrument is described as useful for this purpose, although it is not the definitive version to perform CVrSO measurements in children and adolescents on the Colombian Caribbean coast.

Introduction: the oral health related quality of life measurement is considered a daily life negative effect indicator due to patients’ oral condition. The Oral Health Impact Profile (OHIP-49) is an extended-use instrument, the readers should to expect the researchers to present the psychometric properties analysis, which describe the instrument behavior in the study population. The purpose is to evaluate the OHIP-49 reproducibility properties when is applied in patients with periodontal disease, who attend two dental healthcare institutions. Methods: we included 207 participants how it is suggested from the International Test Commission for similar purposes. We included 91 men and 116 women for convenience; reproducibility properties were evaluated: reliability, internal consistency, item discriminant validity, and content validity. Results: Cronbach’s alpha of 0.951 was obtained and high success percentages for internal consistency (87.5%-100%); the item discriminant validity not achieved acceptable success percentages (16,6% -68,5%). We decided to review the instrument content structure, with which a seven-factor model was obtained. According to the clinical situation, when we compared them with the less severe cases, patients with periodontitis stage III and IV presented worst quality of life represented in the dimensions of functional limitation, chewing, swallowing and aesthetics. Conclusions: a good instrument performance was obtained for this Colombian Caribbean Coast population; but it is valid to consider reducing dimensions to improve reproducibility scores.
