Validity and reliability of the Patient Health Questionnaire-8 in Swedish for individuals with systemic sclerosis.
Article in Rheumatology international, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers.
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
backgroundDepressive symptoms are common in rheumatic diseases and influence patients' quality of life. The Patient Health Questionnaire-9 (PHQ-9), which assesses symptoms of depression, is valid in English in patients with systemic sclerosis (SSc). However, the measurement properties of the PHQ-8 (short version of the PHQ-9) have not been evaluated in Swedish patients with SSc.
objectiveTo investigate different aspects of validity and reliability of the PHQ-8 in Swedish (PHQ-8 Swe) for individuals with SSc.
methodsA total of 101 patients with SSc participated. Content validity was evaluated via interviews of 11 patients and 10 health professionals. Construct validity, internal consistency test-retest reliability, and floor/ceiling effects were evaluated in 90 patients.
resultsContent validity was satisfactory, but some linguistic adjustments were made. Confirmatory factor analysis supported a better fit for a two-factor structure. Moderate-to-strong correlations were found between the PHQ-8 Swe and scleroderma HAQ including VAS (r
conclusionThe PHQ-8 Swe has satisfactory content validity and sufficient reliability in patients with in majority limited SSc. It is more strongly associated with self-reported disability, pain, disease interferences with daily activities, fatigue, and quality of life than with disease severity, except for a moderate association with lung severity.
