An interview technique in assessing retarded children. A comparative study of the reliability of the Children's Handicaps, Behaviour and Skills (HBS) Schedule.
A new assessment instrument the Children's Handicaps, Behaviour and Skills Schedule (HBS Schedule), constructed in England, has been used in a Danish epidemiological survey to interview the parents and professionals involved with 148 severely retarded children. Results as to reliability between informants and congruity with similar results from a study in Camberwell, England, are presented and discussed. It is concluded that the HBS Schedule constitutes a very valuable supplement in the evaluation of such children and deserves propagation for routine application, provided satisfactory instructions to interviewers can be given.
