The participants were 2,000 Russians (1,000 men and 1,000 women) aged 18 to 60 years (M = 38.78; SD = 9.25).Results. The psychometric analysis confirmed the internal reliability and discriminative validity of the adapted questionnaire. The proof of the factor validity of the Russian version of the PHQ-4 was the identification of a two-factor structure describing the symptoms of anxiety and depression, and factor invariance by age, level of education, marital status, parental status, financial status and place of residence. Among the Russians, 44.9% had clinically significant anxiety symptoms and 42.9% had clinically significant depressive symptoms.
