Turkish reliability of the patient health questionnaire-9
Objective: Our aim was to adapt for Turkish and perform the reliability study of The Patient Health Questionnaire-9 (PHQ-9).
Material and methods: PHQ-9 was translated to Turkish by three researchers and a consensus meeting was held after the translation process. Turkish text on which the researchers agreed was translated into English by an independent professional translator. As a result of this process, the researchers obtained the final version on which they agreed and the accuracy of which was proved by back translation.
Results: The questionnaire was administered to patients above 18 years presenting to Family Medicine clinic. Total of 96 patients (42 male 54 female, with an average age of 37.63 ± 11.66 years) took part in this study. Turkish version of the questionnaire was found to be quite reliable. (Cronbach’s alpha 0.842)
Conclusion: Turkish version of The Patient Health Questionnaire-9 is quite reliable. We believe that this questionnaire may be used for objective assessment of diagnosing depression, evaluating its severity and its follow-up in clinical practice.Author(s): Yunus Emre Sari, Burcu Kokoglu, Huseyin Balcioglu, Ugur Bilge, Ertugrul Colak, Ilhami Unluoglu
