The Dutch version of the Oral Health Impact Profile (OHIP-NL): Translation, reliability and construct validity

Abstract

BackgroundThe purpose of this study was to make a cross-culturally adapted, Dutch version of the Oral Health Impact Profile (OHIP), a 49-item questionnaire measuring oral health-related quality of life, and to examine its psychometric properties.MethodsThe original English version of the OHIP was translated into the Dutch language, following the guidelines for cross-cultural adaptation of health-related quality of life measures. The resulting OHIP-NL's psychometric properties were examined in a sample of 119 patients (68.9 % women; mean age = 57.1 ± 12.2 yrs). They were referred to the clinic of Prosthodontics and Implantology with complaints concerning their partial or full dentures or other problems with missing teeth. To establish the reliability of the OHIP-NL, internal consistency and test-retest reliability (N = 41; 1 – 2 weeks interval) were examined, using Cronbach's alpha and intraclass correlation coefficients (ICC), respectively. Further, construct validity was established by calculating ANOVA.ResultsInternal consistency and test-retest reliability were excellent (Cronbach's alpha = 0.82 – 0.97; ICC = 0.78 – 0.90). In addition, all associations were significant and in the expected direction.ConclusionIn conclusion: the OHIP-NL can be considered a reliable and valid instrument to measure oral health-related quality of life.

Psychometric properties and performance of the Oral Health Impact Profile (OHIP-14s-ar) among Sudanese adults

“…This study demonstrated that the OHIP is internally consistent (as shown by the Cronbach α). The Cronbach α for internal consistency in this study was slightly lower than in studies by van der Meulen or John (23,36), similar to values obtained by Slade and Spencer (10), and higher than those from Lopez (38).…”

“…Our values were slightly higher than those reported in other studies (23,36). The adequate reliability on the OHIP-14s-ar was confirmed by the Bland-Altman plot (34), which showed that 95% of differences were within the limits of agreement.…”

“…The cross-cultural adaptation of the OHIP-14s-ar was done using published guidelines (23,36,37). Even though the OHIP-49 had been previously translated into Arabic (22) and used in a Saudi population, cultural differences and difficulty in understanding some of the questions led us to develop a version more suitable for the Sudanese population.…”

“…To create an Arabic version of the OHIP-14, translation guidelines using a forward-backward approach were followed based on previous studies (22,23). For the forward translation, two teams of bilingual dentists first independently translated the English version of the OHIP-14.…”

Application of the Oral Health Impact Profile (OHIP) among Taiwanese elderly

“…Therefore, the OHIP-49 has been translated and validated in several countries [4][5][6][7][8][9][10][11]. A Chinese version of the OHIP was developed by Wong and McMillan [4] for the Hong Kong elderly.…”
