The EQ-5D index score of the depressive group was significantly lower than that of the normal group.Ĭonclusion: The PHQ-2 is an effective measure for screening depression and is expected to be useful in busy clinical settings. The agreement between PHQ-2 and ‘depression by questionnaire’ was poor. The Mood Disorders Questionnaire (MDQ) is a valid, reliable instrument that.
The agreement between PHQ-2 and depression by PHQ-9 was 0.430 when PHQ-2 ≥2 was used as a cut point. The Patient Health Questionnaire-Adolescent Version (PHQ-9) is a nine-item. Results: Using ‘depression by PHQ-9’ as the criterion standard, PHQ-2 scores ≥2 had a sensitivity of 89% and a specificity of 87%, and a receiver operating characteristic analysis identified PHQ-2 ≥2 as the optimal cut point for screening. The correlation between EuroQol-5D (EQ-5D) index scores and PHQ-2 scores was analyzed using Student’s t-test. The Severity Measure for DepressionChild Age 1117 (adapted from PHQ-9 modified for Adolescents PHQ-A) is a 9-item measure that assesses the severity of depressive disorders and episodes (or clinically significant symptoms of depressive disorders and episodes) in children ages 1117. The agreement between PHQ-2 and depression by PHQ-9 and the agreement between PHQ-2 and ‘currently diagnosed as depression’ were analyzed using Cohen’s kappa. We analyzed the validity of the PHQ-2 compared with ‘depression by PHQ-9,’ and obtained the optimal cut point for screening depression. Methods: This study used Korean National Health and Nutrition Examination Survey data from 2014, and the study population consisted of 4,946 individuals.
This study aimed to assess the usefulness of the PHQ-2 as a brief screening tool for depression. The Patient Health Questionnaire-2 (PHQ-2) consists of two questions gauging the frequency of depressed mood and anhedonia over the past two weeks. Abstract Background: While various screening tools are available for depression, they are not feasible in clinical practice because of their excessive number of questions.
