Background: Movement quality is an important aspect in clinical reasoning. The observable movement quality scale (OMQ-scale), a 15-item questionnaire, has been developed for use alongside an age-specific motor test.
Purpose: To determine the interrater reliability of the OMQ-scale in children from 6 months to 6 years of age.
Methods: Pediatric physical therapists (n = 28; 2 male, 26 female), observed age-related discriminative motor tests in video-recorded children (n = 9), and filled in the OMQ-scale (range 1575). We used linear mixed models to study random measurement error and the differences between subgroups (three based on work setting, two based on working experience).
Results: Interrater reliability was moderate (ICC: 0.67, 95% CI [0.47, 0.88]). The random measurement error was 5.7; no statistically significant differences were found between work setting groups and working experience group.
Conclusion(s): Experienced and novice therapists showed moderate interrater reliability after only a 2-hour training. The results are promising and feedback suggested a need for a more comprehensive training for using the OMQ-scale in clinical practice, which may further increase interrater reliability.
Implications: Research for the determination of remaining psychometric properties are planned, needed before the OMQ-scale will be furhter implemented in clinical practice.
