Psychometric properties of a Turkish version of the oral health impact profile‑14
Objectives: The purpose of this study was to analyze and evaluate a Turkish translation of the oral health impact profile‑14 (OHIP‑14) in a Turkish population to provide an objective standard for future studies.
Methods: This cross‑sectional research study consisted of three independent studies. Data were collected utilizing a personal interview and a review of periodontal records. This study was performed on 1205 subjects who were visiting for routine medical check‑ups. The OHIP‑14 was administered to measure oral health related to the quality of life, along with a questionnaire addressing demographic information, such as age, gender, and education.
Results: The reliability coefficient (Cronbach’s alpha) of the Turkish version OHIP‑14‑TR (OHIP‑14‑TR) was reported to be nearly perfect in all 3 parts of our study (alpha 1: 0.82; alpha 2: 0.76; alpha 3: 0.91); additionally, values were greater than the recommended 0.70 threshold. Spearman’s correlation coefficients showed that both OHIP scores significantly correlated with periodontal parameters, serving as proof of convergent validity (P < 0.01, P < 0.001). The principal component analysis with varimax rotation revealed seven factors. The OHIP‑14‑TR was more than 95% comprehensible.
Conclusion: The OHIP‑14‑TR is a reliable, valid, and comprehensible scale for measuring oral health‑related quality of life in the Turkish population.
