Patterns of response to childhood asthma

Area of Science:

• Pediatric Pulmonology
• Child Psychology
• Asthma Research

Background:

• Asthma symptom assessment in children relies on subjective reports, often involving both the child and their parents.
• Understanding the concordance between these perspectives is crucial for accurate diagnosis and treatment monitoring.
• Previous research has explored symptom patterns, but direct comparison of parent-child ratings and their link to objective morbidity is less explored.

Purpose of the Study:

• To evaluate the agreement between parental and child self-ratings of asthma symptoms.
• To determine the relationship between these symptom ratings and objective measures of asthma morbidity.
• To identify distinct symptom patterns in pediatric asthma.

Main Methods:

• A modified Asthma Symptom Checklist (CASCL) was administered independently to 162 children with asthma and their 105 parents.
• Factor analysis was used to identify symptom patterns from the CASCL data.
• Functional morbidity was assessed using medication levels, emergency room visits, and hospitalizations.

Main Results:

• Factor analysis identified three symptom clusters: General Physical Symptoms, Panic/Fear, and Hyperventilation/Irritability.
• Correlations between parent and child item ratings ranged from 0.00 to 0.35, indicating low to modest agreement.
• Parental factor scores showed significant correlations with functional morbidity indices, while children's factor scores did not.

Conclusions:

• Parental reports of asthma symptoms offer a more reliable indicator of functional morbidity in children than child self-reports.
• Discrepancies in symptom perception highlight the importance of considering both perspectives in clinical practice.
• Further research is needed to understand the reasons behind the differing correlations with morbidity.
