[The Well-Being Questionnaire-12: an evaluation of its validity and reliability in Turkish people with end-stage renal disease].
OBJECTIVE
The aim of the present investigation was to test the psychometric properties of the Turkish version of the Well-Being Questionnaire-12 (WBQ-12) in patients with end-stage renal disease.


METHODS
The subjects included in the study were patients with end-stage renal disease treated in Hemodialysis Unit of Başkent University Medical Hospital. The Patient Information Sheet, the Mini Mental Test, the WBQ-12, the Hospital Anxiety and Depression Scale (HAD) were applied to a total of 60 patients ranging from 19-71 years old. The WBQ-12 was applied for test-retest reliability assessment in 3-7 days after first interview.


RESULTS
The item-total score correlation of the WBQ-12's items was 0.43, Cronbach's alpha coefficient was 0.87, and test-retest correlation coefficient was 0.80. The optimum cut-off score for the WBQ-12 with respect to detecting anxiety and/or depressive disorder was determined to be 10. Using this cut-off point, the sensitivity, specificity, positive predictive value, and negative predictive value of the WBQ-12 were 0.87, 0.73, 0.50 and 0.92, respectively.


CONCLUSIONS
This short instrument is easy to administer and may be considered a useful tool for both clinicians and researchers to assess the psychological well-being of patients with end-stage renal disease which has high psychiatric comorbidity, and causes disability in high level.
