ObjectiveTo assess the psychometric properties of the Hebrew version of the Patient Health Questionnaire (PHQ-9) in the general population. MethodsUsing an online survey, we assessed test-retest reliability with a two-week time interval. A total of 118 participants enrolled in the study, of whom 103 completed the survey twice. Each participant filled out the PHQ-9 and the 12-Item Short Form Survey (SF-12). Our statistical analysis includes Cronbachs alpha, Intraclass Correlation Coefficient (ICC2,1), Spearmans rank correlation coefficient, Standard Error of Measurement (SEM), and Minimal Detectable Change (MDC). ResultsInternal consistency of the Hebrew version of the PHQ-9 ranged from =0.79-0.83. The test-retest reliability of the questionnaire is good (ICC2,1= 0.81), and it is moderately and negatively correlated to the mental component of the SF-12 (Spearman {rho}= -0.57, p< .05). The SEM of the PHQ-9 is 1.83 points, and the MDC was found to be 5 points. ConclusionThe Hebrew version of the PHQ-9 is valid and reliable for screening self-reported depressive symptoms online in the general Hebrew-speaking population.
