4.0 Limitations

Data routinely collected from C&BT callers could not be linked to the information collected for this study therefore we were not able to calculate the age of the child or infant for whom there was concern. It would be interesting to know the age of children most commonly causing concerns in callers to the C&BT phone line.

The study population is a convenience sample of callers to the phone line so that no information is available about 'non-callers'. Also, callers who seemed particularly anxious or distraught were not asked to answer the additional demographic questions.
