The PEP-R (psychoeducational profile revised) is an instrument that has been used in many countries to assess abilities and formulate treatment programs for children with autism and related developmental disorders. To the end to provide further information on the PEP-R's psychometric properties, a large sample (N = 137) of children presenting…

Autism spectrum disorders (ASD) and intellectual disabilities (ID) are high prevalence developmental disabilities that co-occur at high rates. Furthermore, Axis I psychopathology is known to occur more frequently in individuals with ID than the general population. The problems are lifelong and can be major impediments to independent living.…

This paper considers the measurement of person-centered planning with developmentally disabled individuals. It reports on the development of three instruments to assess person-centered planning and both a process and an outcome index. Psychometric evaluation indicated test-retest reliability and measures of internal consistency were adequate.…

The Early Development Index (EDI) is a teacher-completed checklist, intended to be a population-level tool to measure children's readiness for school and to alert communities to potential developmental problems in children. In response to the increasing popularity of the EDI, this paper provides a critical and timely evaluation and identifies the…

This paper reviews the psychometric properties, treatment utility, and conceptual basis of instruments used to identify the functions of aberrant behaviors in people with developmental disabilities. Instruments include the Motivational Assessment Scale, Motivation Analysis Rating Scale, Functional Analysis Interview Form, and Functional Analysis…

This research was conducted to replicate and expanded the work of Bodfish et al. [Bodfish, J. W., Harper, V. N., Deacon, J. R., & Symons, F. J. (2001, May). "Identifying and measuring pain in persons with developmental disabilities: A manual for the Pain and Discomfort Scale (PADS)." Western Carolina Center Research Reports] by assessing the…

Current methods of assessing and treating aggression in children and adolescents with developmental disabilities were reviewed. While a number of measures have been developed to assess aggression in the general population, there are relatively few assessment methods for use with children and adolescents with developmental disabilities. In all, 54…

The use of anti-epileptic medications (AEDs) is much higher in individuals with intellectual disabilities than in the general population. As many of these individuals rely on such medications, clinicians should consider psychometrically sound instruments for assessing adverse side effects of these medications as one aspect of routine clinical…

Background: Research on prediction of violent and sexual offending behaviour has developed considerably in the mainstream criminological literature. Apart from one publication [Quinsey (2004) "Offenders with Developmental Disabilities," pp. 131-142] this has not been extended to the field of intellectual disabilities. Methods: Work on actuarial…

This paper offers a rationale for and a description of the creation of the Developmentally Delayed Children's Behaviour Checklist, which is completed by caregivers or teachers and uses a taxonometric model to describe the child's (ages 4-20) disturbed emotions and behaviors. Results of clinical validation studies are cited. (Author/JDD)
