Psychometric Validation of the FACE-Q Dental Module in Patients With Malocclusions.
Article in Community dentistry and oral epidemiology, 2025. 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
objectiveThe FACE-Q Craniofacial Module is a patient-reported outcome measure (PROM) developed for children and young adults with craniofacial conditions. We hypothesised that some of its scales may be applicable to other populations. The aim of this study was to assess the validity and reliability of FACE-Q scales for patients with dental malocclusions.
methodsThe FACE-Q Dental Module includes 5 scales from the Craniofacial Module that measure appearance (Face, Jaws, Smile and Teeth) and function (Eating/Drinking). Data were collected from patients aged 8-29 years who presented with a dental malocclusion (pre-treatment) or 1-2 years after orthodontic treatment (post-treatment) at a large university-based orthodontic specialty clinic in Canada between September 2018 and March 2020. Patients completed a paper questionnaire booklet, and data were entered into a Research Electronic Data Capture (REDCap) survey. The psychometric analysis was performed using Rasch Measurement Theory (RMT) analysis.
resultsThe sample of 434 patients was aged 9 to 29 years, with 249 female and 185 male participants. The sample included 252 pre-treatment and 182 post-treatment patients. The 4 appearance scales evidenced strong psychometric performance; all 37 items had ordered thresholds with good item fit to the Rasch model. Reliability was high, with person separation index and Cronbach alpha values, with and without extremes ≥ 0.86. As hypothesised, those participants who had a major difference in appearance, and those who reported liking their appearance less, scored lower on the appearance scales (p < 0.001). In the RMT analysis, the Eating/Drinking scale evidenced low reliability and poor targeting with close to 40% of particpants scoring at the ceiling.
conclusionThe FACE-Q Dental Module provides a means to collect evidence-based outcomes data from children and young adults who undergo orthodontic care for dental malocclusions.
