Factorial structure of the patient health questionnaire-9, generalized anxiety disorder-7 and berger HIV stigma scale-short form among adolescents living with HIV in Ghana.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundMental health issues and stigma experiences significantly affect adolescents living with HIV (ALHIV). While the Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and Berger HIV Stigma Scale-Short Form (HSS-SF) are widely used screening tools for mental health and stigma, their factorial validity among ALHIV in resource-limited settings such as Ghana remains understudied. This study investigated the factor structure, internal consistency, and correlations of the PHQ-9, GAD-7, and HSS-SF among ALHIV in Ghana.
methodsA cross-sectional study was conducted among 105 ALHIV (aged 10-24 years) receiving care at three government hospitals in Eastern Ghana. Confirmatory factor analyses were conducted to examine the factor structure of the PHQ-9 and GAD-7 and HSS-SF.
resultsA two-factor structure showed the best fit for PHQ-9, with satisfactory internal consistency for cognitive/affective (α = 0.79) and somatic factors (α = 0.70). The GAD-7 demonstrated best fit as a unidimensional factor structure, with acceptable internal consistency (α = 0.88). The HSS-SF was found to be best represented by a three-factor structure, with internal consistency ranging from 0.76 to 0.95 across subscales.
conclusionsThe PHQ-9, GAD-7, and HSS-SF demonstrated acceptable factorial structure and internal consistency among Ghanaian ALHIV, supporting their utility as screening tools in this population.
