A Danish version of the oral health impact profile-14 (OHIP-14): translation and cross-cultural adaptation

Abstract

Background The Oral Health Impact Profile-14 (OHIP-14) questionnaire assesses quality of life related to people’s perception of oral disorders on their well-being. However, a translated and validated Danish version of OHIP-14 is not yet available. The purpose of this pilot study was to translate and cross-culturally adapt the English version of the OHIP-14 into Danish (OHIP-14-DK). In addition, to assess its content and face validity, internal consistency and test-retest reliability. Methods The English version of OHIP-14 was translated into Danish following a standard protocol of cross-cultural adaptation. Stages I-IV: translation phase to generate a pre-final version “OHIP-14-DK”. Stage V: pre-testing phase. A random sample of 22 orthodontic patients (mean age 24.7 years, SD ±14.8; 14 females, 8 males) were selected at the Section of Orthodontics, Aarhus University, Denmark. All patients self-completed the OHIP-14-DK and were then interviewed to assess its content and face validity. Internal consistency was assessed with Cronbach’s alpha coefficients. All patients completed the same questionnaire again at a one-week interval. Test-retest reliability was assessed using Spearman’s correlation coefficient and intra-class correlation coefficient (ICC). Results The initial and back translations were very similar: the OHIP-14-DK proved to have a good level of equivalence with no translation errors or deviations. Furthermore, the OHIP-14-DK seemed well-adapted to Danish culture and was understood by individuals down to 12 years of age. Pre-testing demonstrated good face and content validity; interviews had a response rate of 100% and confirmed that each item was understandable without inducing reluctance or hesitation. Thus, responses were related to their corresponding item. Therefore, no final adjustments were required for the pre-tested version. Cronbach’s alpha for the OHIP-14-DK subscales fell in the 0.75–0.84 range, indicating an adequate-to-good internal consistency. Spearman’s correlation coefficient for the OHIP-14-DK total score was 0.77. The ICC for the OHIP-14-DK total score was 0.91. Conclusions The OHIP-14-DK seems well adapted to Danish culture, proved to be face and content valid and also showed good internal consistency and excellent reliability. However, its psychometric properties still need to be tested. Study registration Not applicable

Translation and content validation of the trans-contextual model questionnaire battery and development of a web-based version for 10-to 12-year-old Danish schoolchildren

“…Denmark has implemented comprehensive national IT strategies in recent years (EU, 2020), making the use of web-based questionnaires applicable and easy to use for this age group and within this culture (Statistik, 2019). However, in newly translated versions of web-based questionnaires, comprehensibility is of major importance (Gera et al, 2020), which is why we emphasized content validity in our study. This is important since the translated web-based version is to be used within the large-scale school-based 11 for Health concept.…”

“…However, web-based administration may yield slightly different results compared to paper-based versions as the web-based administration is seldomly done in a controlled setting (Austin et al, 2006;Donker et al, 2010). Therefore, content validity of the web-based TCM questionnaire must also be established (Gera et al, 2020;Terwee et al, 2018). Since the target users of the 11 for Health concept (i.e., 10-to 12-year-old schoolchildren) are not capable of translating a comprehensive English questionnaire, it is essential to involve them in other ways in the translation and adaptation process.…”

Factors Affecting Care and Maintenance of Complete Denture Prostheses (CDP)-A Literature Review

“…In addition, that had been no major impact of LcS on occurrence and success rates of Candida. CDP patients had an exceptional general knowledge of CDP hygiene and it was also highlighted that the responses made to OHIP-14 questionnaires had also shown improvement upon completion of the study (Sutula et al, 2012;Gera, Cattaneo, & Cornelis, 2020).…”

Use of Oral Health Impact Profile-14 (OHIP-14) in Different Contexts. What Is Being Measured?

“…A reduction of items was performed using statistical procedures on sample data from Australian individuals aged over 60 years [5]. Since its publication, the OHIP-14 has been translated and adapted into different languages [10][11][12][13][14]. It has also been widely applied in different samples and contexts different from those in which the instrument was proposed and evaluated, for example, in the general population (non-patient) [12,13,15], young orthodontic patients [11], indigenous population [15] and postpartum women [10,16].…”
