Background for and development of a brief Children's Behavioral Classification Project Inventory.

A brief form of the Children's Behavioral Classification Project Inventory was developed. A Proto-CBCP Inventory consisting of 229 behavioral items and 11 demographic variables was administered to 351 parents of children with clinical problems and 80 normal control parents. The analyses of these data were thoroughly criticised by experts in psychology and related fields. From this critique and trial runs which included 22 demographic variables, a full inventory of 274 behavioral items plus child's age, sex and clinic vs nonclinic status resulted; this inventory has a 30-factor structure. Given the length of the full-scale inventory and the number of factors derived from it, a briefer form was created consisting of 189 items from which were derived 13 factors. This inventory was standardized on a total n of 1379 for use as a screening device in clinics.
