The validity and reliability of the Patient Health Questionnaire - Adolescent version (PHQ - A) in Vietnam.
Article in BMC psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe two cross-sectional studies were conducted to examine the validity and reliability of the Patient Health Questionnaire for Adolescents (PHQ-A) in a sample of Vietnamese adolescents.
methodParticipants were recruited from secondary schools (grades 6 to 9) and high schools (grades 10 to 12) in Ho Chi Minh City, comprising 68 students in Study 1 and 624 students in Study 2. The scale was translated into Vietnamese following standard forward–backward translation procedures. PHQ-A scores were compared with clinical diagnoses based on DSM-5 criteria, and the psychometric properties of the scale were evaluated through test–retest reliability, internal consistency analyses, confirmatory factor analysis (CFA), and assessments of convergent validity.
resultsThe findings indicated that PHQ-A have a sensitivity of 91.89% and a specificity of 70.97% for a cut-off point of 10. The scale also had a high internal consistency with Cronbach’s α exceeding 0.80 and McDonald’s omega total of 0.80. The confirmatory factor analysis validated the original structures of the PHQ-A, demonstrating acceptable fit indices. Furthermore, the scale revealed significant correlations with the ESSA, thereby affirming its convergent validity.
conclusionThe findings indicate that the PHQ-A is appropriate for extensive initial assessment and screening in educational institutions, healthcare centres, and other time-limited contexts.
