Background: Treatment for adults who set fires relies upon valid and reliable assessment. Research is needed to ensure self-report measures are available for adults with neurodevelopmental disabilities and that they are robust. Method: Qualitative and quantitative data from three rounds of a Delphi exercise with practitioners and a focus group…

Strategies for the early detection of autism spectrum disorders (ASD) in people with intellectual developmental disorder (IDD) are urgently needed, but few specific tools have been developed. The present study examines the psychometric properties of the EVTEA-DI, a Spanish adaptation of the PDD-MRS, in a large randomized sample of 979 adults with…

Background: Sensory irregularities are commonly seen across developmental and intellectual disability groups. Identifying patterns of dysfunction within these clinical groups facilitates the development of appropriate intervention strategies. Thus, we evaluated the psychometric properties of the new Sensory Processing (SP) Scale Inventory rating…

The Delis Rating of Executive Function (D-REF) is a set of rating scales designed to assess executive functions and their constituent sub-processes in children and adolescents between the ages of 5 and 18. More specifically, the D-REF is a supplemental assessment of children and adolescents demonstrating behavioral or cognitive difficulties often…

Reliable and valid assessment of aberrant behaviors is essential in empirically verifying prevention and intervention for individuals with intellectual or developmental disabilities (IDD). Few instruments exist which assess behavior problems in infants. The current longitudinal study examined the performance of three behavior-rating scales for…

Purpose: Accurate description of an individual's communication status is critical in both research and practice. Describing the communication status of individuals with severe intellectual and developmental disabilities is difficult because these individuals often communicate with presymbolic means that may not be readily recognized. Our goal was…

Roth's Mother Child Relationship Evaluation was administered to 54 mothers and 20 fathers of children aged 3 to 11. The underlying dimensions--acceptance, overprotection, overindulgence, and rejection--were also assessed. Results suggested the need for both revision and renorming of the instrument. (Author/GDC)

To assess the psychometric characteristics of the Verbal Behavior Assessment Scale, the 15-item questionnaire was administered to pairs of caregivers of 115 individuals with developmental disabilities. Exploratory factor analysis involving 11 more participants revealed evidence concerning the distinction of three different communicative functions…

Comparison using paired t-tests of parent and teacher ratings for 16 preschool children on the Receptive-Expressive Emergent Language Scale found no significant differences between parent and teacher ratings of expressive language, but a significant difference on the receptive language subscale. However, interrater reliability was relatively low…
