Abstract

Objectives To adapt and validate the OAKHQOL for using in osteoarthritis patients of Turkish population.

Methods The cross-cultural adaptation of OAKHQOL according to guideline used forward and backward translations from French to Turkish, with an emphasis on expert committee informed decision making. Patients with knee and hip osteoarthritis were recruited into the study. Systemic inflammatory rheumatic diseases were in exclusion criteria. Internal consistency of OAKHQOL subgroups were assessed. Face and content validity were assessed via cognitive debriefing interviews with OA patients. The OAKHQOL subgroups were correlated with SF36, Lequesnes index, Nothingam Health Profile (NHP), WOMAC and VASpain to evaluate construct validity. Spearman correlation coefficient managed to compare qualitative parameters. p<0.05 was significant.

Results Eighty two patients (63 female) with aged 56,31 (SD:11,12) years were recruited. Sixtynine patients had osteoarthritis at knees, 11 had at hips and 2 patients had both. The Body Mass Index (BMI) was 27,19 (SD:3,90) and the disease duration was 4,77 years (range: 0,5 – 30). The internal consistency of OAKHQOL subgroups (1 to5) were 0,80; 0,51; 0,87; 0,77 and 0,31. The mean scores of subgroups were 47,19 (SD: 19,77); 42,46 (SD: 34,58); 56,47 (SD: 22,96); 59,92 (24,89) and 49,75 (34,32). According to expert and patient desicions the Turkish version of OAKHQOL had good face and content vaidity. The physical activity, pain and mental health subgroups of OAKHQOL had significant correlation with all subgroups of SF36. The social support and social activities subgroups had not significant correlation with SF36 scores. Lequesnes index had good correlation only with physical activity (p=0,001) and pain (p<0,0001) subgroups of OAKHQOL. The total score of WOMAC had significant correlation with the physical activity (p=0,001), pain (p=0,001) and mental health (p=0,001) subgroups of OAKHQOL. Physical activity and pain subgroups of NHP had significant correlation only with the physical activity, pain and mental health subgroups of OAKHQOL. There was not any significant correlation with social support and social activities subgroups of OAKHQOL with other quality of life scales.

Conclusions The psychometric properties of Turkish version of OAKHQOL show that it is useful scale to assess the quality of life of patients with knee and hip osteoarthritis in our population.
