AIM To determine the most accurate parent-reported indicators for detecting (1) feeding/
swallowing difficulties and (2) undernutrition in preschool-aged children with cerebral palsy
(CP).
METHOD This was a longitudinal, population-based study, involving 179 children with CP,
aged 18 to 60 months (mean 34.1mo [SD 11.9] at entry, 111 males, 68 females [Gross Motor
Function Classification System level I, 84; II, 23; III, 28; IV, 18; V, 26], 423 data points).
Feeding/swallowing difficulties were determined by the Dysphagia Disorders Survey and 16
signs suggestive of pharyngeal phase impairment. Undernutrition was indicated by
height–weight and skinfold composite z-scores less than À2. Primary parent-reported
indicators included mealtime duration, mealtime stress, concern about growth, and
respiratory problems. Other indicators were derived from a parent feeding questionnaire,
including ‘significant difficulty eating and drinking’. Data were analysed using multilevel
mixed-effects regression and diagnostic statistics.
RESULTS Primary parent-reported indicators associated with feeding/swallowing were
‘moderate–severe parent stress’ (odds ratio [OR]=3.2 [95% confidence interval {CI} 1.3–7.8];
p<0.01), ‘moderate–severe concern regarding growth’ (OR=4.5 [95% CI 1.7–11.9]; p<0.01), and
‘any respiratory condition’ (OR=1.8 [95% CI 1.4–5.8]; p<0.01). The indicator associated with
undernutrition was ‘moderate–severe concern regarding growth’ (height–weight OR=13.5
[95% CI 3.0–61.3]; p<0.01; skinfold OR=19.1 [95% CI 3.7–98.9]; p<0.01). ‘Significant difficulty
eating and drinking’ was most sensitive/specific for feeding outcome (sensitivity=58.6%,
specificity=100.0%), and ‘parent concern regarding growth’ for undernutrition
(sensitivity=77.8%, specificity=77.0%).
INTERPRETATION Parent-reported indicators are feasible for detecting feeding and
swallowing difficulties and undernutrition in children with CP, but need formal validation.
There is growing awareness of the significance of undernu-
trition as a foundational health concern for children with
cerebral palsy (CP).

It has been well documented that
feeding and swallowing difficulties, and consequent limita-
tions to dietary intake, are important underlying factors
contributing to undernutrition in this population.

Diffi-
culties with feeding and swallowing can also result in pro-
longed and stressful mealtimes, and reduce the safety of
the swallow. Feeding and swallowing difficulties persist in
approximately two-thirds of preschool-aged children with
CP

and, as such, form part of their expected clinical
profile. To facilitate earlier management of feeding and
swallowing difficulties and undernutrition, it is important
to develop efficient and effective screening tools for use in
children with CP.
Parent-report has frequently been used as a measure
of feeding and swallowing difficulties in children with
CP.
3,5–7
Studies using parent-report to identify feeding and
swallowing difficulties in CP have used structured or semi-
structured item protocols that were developed for the study
alone. Only three of seven questionnaires documented a
formal development phase (including literature review,
