Trunk appearance perception scale (TAPS) discrepancy between adolescents with idiopathic scoliosis and their parents influences HRQL

Background The Trunk Appearance Perception Scale (TAPS) is a valid instrument to assess self-perception of trunk deformity [1]. The SRS-22 has been widely used to measure Health Related Quality of Life in scoliosis population, but it is not clear which factors can influence its final score [2]. Children and parents can perceive trunk deformity differently, and discrepancy can be assessed with a coefficient of discrepancy (CD= TAPS major TAPS minor x 100/ TAPS major). We already found that the CD influences the SRS-22 score. However, the previous study included patients older than 18 years, both genders, and results were not reported according to age [3].
