Psychometric properties of the Chinese Behavior Problems Inventory-01 in children and adolescents with or at risk for intellectual disabilities.

As the world's most populous country, China is likely to have the highest number of people with intellectual disabilities (ID) in the world. As many people with ID are susceptible to serious and persistent behavior problems, research by Chinese scientists on this public health issue is needed. However, there are only very few reliable Chinese-language behavior assessment instruments for problem behaviors. To fill this gap we translated the Behavior Problems Inventory-01 (BPI-01; Rojahn, Matson, Lott, Esbensen, & Smalls, 2001) into Chinese. The BPI-01 is an informant-based behavior rating instrument that was designed to assess self-injurious behavior (SIB), stereotyped behavior, and aggressive/destructive behavior in individuals with ID. We then assessed the behavior of 222 children and young adults (age range 1.5-21.5 years) with or at risk for ID from three special needs service programs in mainland China. Teachers or staff members, respectively, served as respondents. The Chinese version of the BPI-01 showed good reliability (internal consistency) and good factor validity tested by confirmatory factorial analysis. We conclude that the Chinese version of the BPI-01 can be used for research and clinical evaluation of Chinese children and adolescents with ID.
