Abstract

<h4>Objective</h4>Treatments for cystic fibrosis (CF) are complex, labour-intensive, and perceived as highly burdensome by caregivers of children with CF. An instrument assessing burden of care is needed.<h4>Design</h4>A stepwise, qualitative design was used to create the CLCF with caregiver focus groups, participant researchers, a multidisciplinary professional panel, and cognitive interviews.<h4>Main outcome measures</h4>Preliminary psychometric analyses evaluated the reliability and convergent validity of the CLCF scores. Cronbach's alpha assessed internal consistency and t-tests examined test-retest reliability. Correlations measured convergence between the Treatment Burden scale of the Cystic Fibrosis Questionnaire-Revised (CFQ-R) and the CLCF. Discriminant validity was assessed by comparing CLCF scores in one vs two-parent families, across ages, and in children with vs without <i>Pseudomonas aeruginosa</i> (<i>PA</i>).<h4>Results</h4>Six Challenge subscales emerged from the qualitative data and the professional panel constructed a scoresheet estimating the Time and Effort required for treatments. Internal consistency and test-retest reliability were adequate. Good convergence was found between the Total Challenge score and Treatment Burden on the CFQ-R (<i>r</i>=-0.49, <i>p</i> = 0.02, <i>n</i> = 31). A recent <i>PA</i> infection signalled higher Total Challenge for caregivers (<i>F</i>(23)11.72, <i>p</i> = 0.002).<h4>Conclusions</h4>The CLCF, developed in partnership with parents/caregivers and CF professionals, is a timely, disease-specific burden measure for clinical research.
