Summary
Developing a new tool to assess cystic fibrosis (CF) medication knowledge in children and their caregivers is crucial. This validated questionnaire can personalize education, potentially improving treatment adherence and health outcomes for pediatric CF patients.
Area of Science:
- Pediatric Pulmonology
- Health Education
- Psychometrics
Background:
- Low adherence to cystic fibrosis (CF) treatment negatively impacts patient health outcomes.
- Increased knowledge of CF and its treatment regimen is linked to better adherence.
- A validated tool is needed to assess medication knowledge in pediatric CF patients and caregivers.
Purpose of the Study:
- To develop and validate a questionnaire assessing medication knowledge in pediatric patients with cystic fibrosis and their caregivers.
- To provide a tool for identifying knowledge gaps to enable personalized educational interventions.
Main Methods:
- A 37-item questionnaire (22 selected-response, 15 open-response) was developed.
- Content validity was established through expert review based on Standards for Educational and Psychological Testing.
- Field testing was conducted with 17 pediatric CF patients and 18 caregivers.
Main Results:
- The questionnaire demonstrated strong internal consistency, with an overall Cronbach's α of .84.
- A medium, though not statistically significant, correlation (r = .33, P = .189) was found between age and medication knowledge.
- Participants found the questionnaire relevant and suitable, offering minor suggestions for wording improvements.
Conclusions:
- The developed questionnaire possesses strong validity evidence for assessing pediatric CF medication knowledge.
- This tool can facilitate tailored educational strategies to enhance treatment adherence in pediatric CF populations.
- Improved adherence through personalized education holds the potential to positively influence health outcomes in cystic fibrosis.

Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...
