Parents' or caregivers' perceptions of their infants' overall developm
ent may serve as a reliable screen for clinical decisions regarding th
e need for further assessment. To determine whether caregivers were ac
curate in estimating infant development, 27 caregivers were asked to a
nswer four questions about their infants before standardized assessmen
t by a paediatric physical therapist. Their responses were compared wi
th the professional's ratings on the Bayley Scales of Infant Developme
nt. Specificity of the parents' estimate with the Bayley Mental Scale
was 85.9 per cent and sensitivity 60 per cent; using the Bayley Motor
Scale as the outcome criterion, specificity reached 90.9 per cent and
sensitivity 80 per cent. Results of this pilot study support the accur
acy of caregiver estimates of their infants' overall development, thus
suggesting that professionals should pay close attention to caregiver
s' concerns about their children's development.
