Child Amputee Prosthetics Project-Prosthesis Satisfaction Inventory (CAPP-PSI): Validation of Italian Version in...

Area of Science:

• Pediatric Rehabilitation
• Prosthetics and Orthotics
• Health Psychology

Background:

• The Child Amputee Prosthetics Project-Prosthesis Satisfaction Inventory (CAPP-PSI) measures satisfaction in functionality, aesthetics, and service.
• Assessing prosthetic satisfaction is crucial for pediatric amputees' well-being and treatment efficacy.

Purpose of the Study:

• To translate and culturally adapt the CAPP-PSI for the Italian pediatric population.
• To evaluate the psychometric properties of the Italian version of the CAPP-PSI.

Main Methods:

• Translation and cultural adaptation of the CAPP-PSI following international guidelines.
• Psychometric evaluation including internal consistency (Cronbach's alpha) and test-retest reliability (ICC).
• Construct validity assessed through subscale correlation analysis in 113 pediatric amputees.

Main Results:

• The Italian CAPP-PSI demonstrated excellent internal consistency (Cronbach's alpha = 0.913) and strong test-retest reliability (ICC = 0.966).
• Significant correlations were found between child and parent satisfaction, and parent satisfaction with services.
• Moderate correlations were observed between child satisfaction and service satisfaction.

Conclusions:

• The Italian CAPP-PSI is a valid and reliable instrument for evaluating prosthetic satisfaction in children with limb loss.
• Findings support its use by clinicians and researchers to enhance patient-centered prosthetic care.
• The tool can guide improvements in prosthetic design and service delivery for pediatric amputees.
