Abstract
Objective:
The purpose of this study was to develop a Turkish version of the mini Osteoporosis Quality of Life Questionnaire (mini-OQLQ), and assess its reliability and validity.
Material and method:
Sixty-four women with postmenopausal osteoporosis were included in the study. Patients who were diagnosed with secondary osteoporosis through clinical and laboratory examinations were excluded from the study. After translation process, the Turkish version of the scale was applied to each participant twice with an interval of 2 weeks. For reliability study, internal consistency (Cronbach’s α) of mini-OQLQ total score and test-retest intraclass correlation coefficient (ICC) were calculated. Validation study was assessed by correlating the scale with QUALEFFO 41.
Results:
The mean age at menopause and age of patients were 45.61 ± 6.04 and 59.91 ± 8.69 years, respectively. Cronbach’s α of the Turkish version of the mini-OQLQ was 0.898. The test-retest reliability (ICC) of the Turkish version of the mini-OQLQ was determined as 0.81 for the total score, and ranged between 0.71 and 0.84 for individual items. In terms of validity, the Turkish version of mini-OQLQ showed significant negative correlation with QUALEFFO 41 (r= –0.756; p < 0.0001).
Conclusion:
The Turkish version of the mini-OQLQ was found to be reliable and valid in the evaluation of life quality of patients with postmenopausal osteoporosis.
