Oral Impacts on Daily Performance in Norwegian adults: validity, reliability and prevalence estimates

Abstract

The Oral Impacts on Daily Performance (OIDP) instrument was translated into Norwegian and reviewed for cultural and conceptual equivalence by a group of bilingual academics. A sample of employees from the University of Bergen completed the Norwegian OIDP frequency questionnaire twice. A total of 173 and 108 subjects participated in the first and the second administration, respectively, of this questionnaire. A two-stage proportionate random sample, comprising 2,000 residents (age-range 16-79 yr), was drawn from the national population register by the Central Bureau of Statistics. Information became available for 1,309 persons who completed telephone interviews. The Norwegian OIDP preserved the overall concept of the English version. Test-retest reliability, in terms of Cohen's kappa, was 0.65, and Cronbach's alpha was high (> or = 0.80). In both samples, variations in the OIDP scores were apparent in relation to self-reported oral health and number of remaining teeth, supporting construct and criterion validity of the inventory. Only three of the OIDP interviews were discarded, which supports face validity. A total of 18.3% confirmed that they had at least one oral impact. Age-specific rates were 17.5%, 19.0%, 17.9% and 18.4% among 16-24, 24-44, 45-66 and 67-79-yr-old participants. The satisfactory psychometric properties provide evidence for the cross-cultural use of the OIDP. The presence of a distinct floor effect indicates poor sensitivity of the OIDP to detect improvements of oral health-related quality of life at a population level. Prevalence estimates were low, suggesting that the current oral health status has little impact on the daily performance of the Norwegian adult population.

Evaluation of oral health-related quality-of-life in patients with generalized aggressive periodontitis

“…They reported that the missing teeth and periodontal pockets were problems and these negatively affected patients' quality-of-life. Previous studies reported a close relationship between missing teeth and OHRQoL [23,25,26]. This study also showed that social aspects were the items most affected by missing teeth.…”

Oral Health-related Quality of Life in Czech Population

“…It was also found that cultural differences in subjects with own teeth do not play a role in the perception of oral problems to their quality of life. Therefore it is recommended to use some of the existing methods (9,33,35). In the field of dentistry, the Oral Health Impact Profile (OHIP) has been developed to examine whether the oral problems of individuals affect their daily life.…”

Validation of a Persian version of the OIDP index

“…Thus, it is important to carry out a rigorous translation and validation process before an instrument developed in one culture is used in a different cultural setting [14,21-23]. This study was the first to use the OIDP index on an Iranian population.…”

“…The OIDP has been used in different studies of adult populations in Great Britain and Greece [9,10], Thailand [11], Tanzania [12], Uganda [13], and Norway [14]. The measure has proved to be reliable and valid in cross-sectional population-based studies as well as in studies of patients with specific oral disorders, such as traumatic injuries and malocclusion [15,16].…”
