Construct validity of the Capacity Profile in preschool children with cerebral palsy

Area of Science:

• Pediatric Rehabilitation
• Disability Assessment
• Child Health Outcomes

Background:

• The Capacity Profile (CAP) is a tool designed to classify additional care needs in children with stable conditions.
• Cerebral palsy (CP) is a heterogeneous condition requiring comprehensive assessment of functional abilities and care requirements.

Purpose of the Study:

• To establish the construct validity of the Capacity Profile (CAP) in young children with cerebral palsy (CP).
• To determine the association between CAP domains and established functional and caregiver assistance scales.
• To identify the contribution of individual CAP domains to specific functional outcomes in children with CP.

Main Methods:

• The study involved 72 children diagnosed with cerebral palsy (CP), with varying GMFCS levels.
• Construct validity was assessed by correlating CAP scores with the Dutch Paediatric Evaluation of Disability Inventory (PEDI) scales.
• Stepwise regression analysis was used to determine the predictive contribution of CAP domains to mobility, self-care, and social functionality.

Main Results:

• The CAP demonstrated good construct validity in young children with CP.
• All CAP domains were significantly associated with Functional Skills and Caregiver Assistance scales (p<0.001).
• The CAP-motor domain showed a strong correlation with the Gross Motor Function Classification System (GMFCS) (rho=0.91, p<0.001).
• CAP domains explained a substantial percentage of variance in mobility (74%), self-care (75%), and social functionality (70%).

Conclusions:

• The Capacity Profile (CAP) is a valid tool for assessing care needs in children with cerebral palsy.
• The CAP's comprehensive assessment across multiple body function domains is crucial for understanding functional limitations in CP.
• Findings highlight the importance of considering all CAP domains for a holistic evaluation of children with complex conditions like CP.
