Psychometric properties of the Brazilian version of the Patient Satisfaction Questionnaire.

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
This study aimed to assess the psychometric properties of the Brazilian version of the Patient Satisfaction Questionnaire (PSQ) which assesses the satisfaction of adolescents with orthodontic treatment. The PSQ is a 58-item self-report instrument presenting six subscales (doctor-patient relationship, situational aspects, dentofacial improvement, psychosocial improvement, dental function, and a residual category). The psychometric properties of the Brazilian version of the PSQ (B-PSQ) were assessed in a cross-sectional study with 111 adolescents between 11-18 years who had undergone orthodontic treatment. The sample's features and the questionnaire's characteristics (including the determination of the floor and ceiling effect) were assessed with descriptive statistics. The instrument's internal consistency was assessed by Cronbach's alpha and stability with the intraclass correlation coefficient (ICC) in test-retest reliability. The convergent and discriminant construct validity was also assessed. Data included responses from 106 adolescents, of which 58 (54.7%) were female. The percentage of individuals reaching the floor effect was 0% in all subscales. In four subscales, the percentage of individuals reaching the ceiling effect was <15%. The B-PSQ showed excellent reliability for the total score (Cronbach's alpha=0.919; ICC=0.918), ranging from good to excellent for all subscales. B-PSQ's total score exhibited a high correlation with all five subscales (ρ>0.50). Scores of young adolescents (10-14 years) were significantly higher in the dental function (p=0.018) and situational aspects (p=0.003) subscales, showing the discriminant validity of the instrument. The B-PSQ has good psychometric properties regarding stability and appears to be a valuable instrument to assess the satisfaction of Brazilian adolescents with orthodontic treatment.
