Executive Functioning Predicts Adaptive Functioning and Self-Care Independence in Pediatric Sickle Cell Disease

Area of Science:

• Neuroscience
• Pediatrics
• Psychology

Background:

• Sickle cell disease (SCD) presents unique challenges for adolescents.
• Executive functioning (EF) is critical for daily life skills and independence.
• Transition to adulthood requires robust self-care and disease management abilities.

Purpose of the Study:

• To investigate the impact of executive functioning (EF) on adaptive functioning and self-care independence in pre-transition youth with sickle cell disease (SCD).
• To determine if EF skills predict adaptive functioning and independence beyond other known factors.

Main Methods:

• Thirty-four youth (ages 12-18) with SCD completed neuropsychological assessments.
• Caregivers reported on adaptive functioning, EF behaviors, and self-care independence.
• Hierarchical linear regression analyses were used to assess predictive relationships.

Main Results:

• Youth with SCD demonstrated low-average performance in working memory, processing speed, and EF skills.
• Both performance-based and caregiver-reported EF predicted adaptive functioning and self-care independence.
• These predictions remained significant after accounting for SES, disease knowledge, and intelligence.

Conclusions:

• Executive functioning (EF) skills are vital for self-care and adaptive skills in youth with SCD.
• Neuropsychological screening and tailored interventions are recommended for transition programs.
• Enhancing EF may improve medical self-care and support successful transition to young adulthood.
