Validation of the Polish language version of the Patient Health Questionnaire-9 in a population of adults aged 35–64

Open access

Abstract

Introduction.Depressive disorders are one of the most common psychiatric disorders.Recognition of signs of mental health disorders is not always easy, hence the availability of simple and accurate tools for assessing them is very important in the practice of primary care.Objective.The aim of the study is to assess the theoretical accuracy and reliability of the Patient Health Questionnaire-9 (PHQ-9) in Polish conditions, when applied to general population studies for adults aged between 35-64. Materials and method.The study comprised a population of 4,040 people.Women constituted 59% of the research population and people living in the countryside 65%.The average age of participants was 53.45 ± 7.05 years.According to PHQ-9, 727 people (18.0%) had moderate, moderate to severe or severe depression.PHQ-9 showed a significant positive internal cohesion (Cronbach's alpha = 0.77), and factor charges oscillated between 0.43-0.63,and the R 2 coefficients of determination were in the range of 0.21-0.40. Conclusions.The Polish version of PHQ-9 is a valid tool for diagnosing depression in the general population aged 35-64.Good psychometric properties and compactness make the PHQ-9 a useful clinical and research tool.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
