Evaluation of a Swedish version of the OHIP-14 among patients in general and specialist dental care.
The aim of this study was to investigate the Swedish version of an oral health-related quality of life (OHRQL) instrument, the short form of the Oral Health Impact Profile (OHIP-14), and to assess OHRQL among patients in general dental care and specialist clinics (periodontics, TMD and implant dentistry) in Göteborg, Sweden. Consecutively selected patients were asked to answer the OHIP-14, the General Oral Health Assessment Index (GOHAI) and a questionnaire including socio-demographic, general health and oral health questions. 153 patients (50-89 years old) out of 237 (65%) returned the questionnaires. Cronbach's Alpha among the OHIP items was high (0.93) and the corrected item-scale correlation varied between 0.51 and 0.79. The correlation between the OHIP-14 score and the GOHAI was high (-0.83) indicating good criterion validity. The mean additive OHIP-14 score was 22.6 (SD = 10.5). Implant patients scored significantly higher than other patient groups with respect to missing teeth, dentures and mobile teeth. High scores were also associated with perceived poor general health and dissatisfaction with life-situation. The test-retest reliability was assessed in a separate sample (n = 47) and the correlation coefficient was 0.85. The Swedish version of OHIP-14 demonstrated good reliability and validity. The poorer OHRQL reported by the implant patients reflects the strong association found between OHIP score and dentures and missing teeth, while OHIP-14 did not show similar sensitivity to other impacts of oral disorders.
