My orthopedic brace inventory (MOBI): a new, reliable, and valid questionnaire to identify barriers to brace adherence in adolescent idiopathic scoliosis treatment.
Article in Spine deformity, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
purposeFull-time wearing of an orthopedic brace has demonstrated effectiveness in limiting curve progression in adolescents with idiopathic scoliosis. However, treatment adherence is challenging, with an average wearing time of 13 h/day. Despite this issue, barriers to brace adherence have rarely been studied. The aim of this study was to develop and validate a new instrument tool to evaluate factors influencing brace adherence.
methodsOur study followed the COnsensus-based Standards for the selection of health Measurement INnstruments criteria (COSMIN). A conceptual framework was initially defined, and experts elaborated, reviewed, and selected candidate items. We also investigated the MOBI's factorial structure and its psychometric properties.
resultsThe MOBI initial version included 32 items related to four conceptual barriers to adherence, namely social/emotional, treatment, patient, and health system/professional. The factorial analysis led to an 18-item inventory with an internal consistency of 0.85 with four better-defined barriers (treatment social/emotional support structure, patient's self-image and perception, treatment adverse effects, and treatment acceptability. The MOBI-18f correlates with the SRS-22 domain treatment satisfaction and pain and the SF-12 mental health. Patients with poor brace wear time and more severe scoliosis will score higher on the MOBI-18f questionnaire.
conclusionThe MOBI-18f is a reliable and valid measure of patients' adherence to brace treatment. This questionnaire can be used to develop interprofessional adherence support intervention in AIS patients undergoing brace treatment.
