Cross‑cultural adaptation and psychometric evaluation of oral health impact profile among school teacher community

To translate OHIP‑14 into Hindi and test its psychometric properties among school teacher community.

The OHIP‑14 was translated to OHIP‑14‑H using WHO recommended translation protocol. During pre‑testing, an expert panel assessed content validity of the questionnaire. Face validity was assessed on a sample of 10 individuals. The OHIP‑14‑H was administered on a random sample of 170 primary school teachers. Internal consistency and test‑retest reliability were assessed using Cronbach’s alpha and Intra‑class correlation coefficient (ICC) respectively, with 2 weeks interval. Predictive validity was tested by comparing OHIP‑14‑H scores with clinical parameters. The concurrent validity was assessed using self‑reported oral health and discriminant validity was ascertained through negative association with sociodemographic variables.

The mean OHIP‑14‑H score was 9.57 (S.D = 4.58). ICC and Cronbach’s alpha for OHIP‑14‑H was 0.96 and 0.92 respectively. Concurrent validity using binomial regression model indicated that good (OR = 0.56, 95% CI = 0.55 – 4.47) and moderate (OR = 0.25, 95% CI = 0.17 – 1.87) OHIP‑14‑H scores were negative but significant risk indicators of poor self reported oral health (P < 0.009). Significant predictive validity was observed between OHIP‑14‑H scores and clinical parameters (P < 0.000).

Translated and culturally adapted OHIP‑14‑H indicates good reliability and validity among primary school teachers.
