THE BEHAVIOR PROBLEM INVENTORY - A FURTHER REPLICATION OF ITS FACTOR STRUCTURE

The Behavior Problem Inventory was administered to a random sample of people living in a state school. The scores from all items and from se lf-injury items only were factor analysed. The three scales of the Beh avior Problem Inventory were highly internally consistent. Factor anal ysis of all the items showed some similarities to previous studies, an d factor analysis of the self-injury items showed a very close corresp ondence to two previous studies. The results are discussed in terms of the design of this instrument, the possible multi-factorial nature of self-injury and future research on the design of measures of assessme nts of maladaptive behaviours in people with developmental disabilitie s.
