Validation Study, Posture, Self-PerceptionAbstract
The assessment of self-perceived body
posture still lacks valid instruments that measure the
“perception” construct. This study aims to develop and
validate the content of a questionnaire that assesses
self-perceived static body posture alignment in school-aged
children and adolescents. In total, six experts in postural
assessment and education — three dedicated to clinical
practice and three, to the scientific area — evaluated
the Self-Bodpos proposed instrument by a validation
questionnaire with general and specific questions about
each item and the options for closed answers and contained
spaces for suggestions. The content validity index (CVI) served
to calculate the experts’ responses. In total, two rounds of
evaluations with the experts were necessary. In the first round,
CVI ranged from 90 to 40%, requiring further adjustments
in the drawings and response options. In the second round,
the CVI reached values above 90%, ending the content
validation stage. The Self-Bodpos proposed questionnaire offers
a valid tool to assess children’s and adolescents’ self-perceived
static body posture, which can serve scientific research,
clinical practice, and the educational environment
