Abstract Individuals diagnosed with intellectual and developmental disabilities (IDD) frequently exhibit self-injurious behavior (SIB). Previous research has examined the published literature on behavioral treatments of SIB from 1964–2000. Results suggested that these treatments were highly efficacious at decreasing SIB, particularly when based on the results of a functional assessment. The purpose of this review is to update, replicate, and extend the previous research. The current findings indicate an increase in studies reporting automatically maintained SIB as well as less efficacious treatments overall. Discussion of our conclusions and methods of SIB assessment and treatment are discussed, both as they relate to the previous review and for future directions.

Knowledge about the assessment of personality disorder (PD) in people with intellectual and developmental disabilities (IDD) has improved significantly in the last 15 years. Guidelines have been developed starting with recommendations by Alexander and Cooray (2003) that informant information, observation, and interview should be employed in a convergent assessment. Specific considerations should be given to the features of IDD itself such as delay in perspective taking abilities. While initial research found widely differing prevalence of PD in people with IDD, more recent research following guidelines, has been more consistent. It has also been demonstrated that PD has an orderly relationship with the assessment of general personality and with emotional problems. Recent alterations in the assessment of PD in the general population have been found suitable for people with IDD and it has also been found that generic services for this population are suitable for those with IDD and PD.
