The BODY-Q Belly Button Scale: A Development and Validation Study

Résumé fourni par la source

BACKGROUND: One of the critical steps in abdominoplasty or in reconstructive procedures involving abdominal tissue involves repositioning the belly button. However, there is limited knowledge about patient satisfaction regarding the appearance of the belly button after such procedures. Currently, there is no standardized patient-reported outcome measure designed to assess this outcome. OBJECTIVES: This study aimed to develop and validate a BODY-Q scale that measures patient satisfaction with the appearance of the belly button. METHODS: In Phase 1 (qualitative), patient interview data were used to develop and refine the new BODY-Q scale. In Phase 2 (quantitative), the scale was field-tested through a crowdsourcing platform. Rasch measurement theory analysis was used for item reduction and to examine reliability and validity. Predefined hypotheses were tested by applying a 75% acceptance threshold, which was considered indicative of sufficient evidence for construct validity. RESULTS: The BODY-Q Belly Button scale was refined through qualitative input from 5 patients. Psychometric validation was performed in a sample of 372 participants. Out of the 15 items assessed, 6 were retained in the final scale. This scale showed ordered thresholds, and the data fit the Rasch model (χ2 = 22.72, df = 24, P-value = .54). The scale evidenced reliability, with Person Separation Index and Cronbach α values ≥.81. For construct validity, acceptance of hypotheses was 89%. CONCLUSIONS: The BODY-Q Belly Button scale can be used in clinical practice and in research to assess satisfaction with the belly button from the patient's perspective.
