Deviation scores: An innovative approach to interpreting cognitive test results for individuals with intellectual disabilities.

Background: Students with Intellectual Disability undergo frequent cognitive testing. Testing with this population is limited by insensitivity to relative strengths and weaknesses due to floor effects.

Aim: The study explored the utility of deviation scores via four case studies as a supplement to educational decision-making.

Thriving with Down syndrome: A qualitative multiple case study.

Background: Down syndrome (DS) is the most common genetic cause of intellectual disability. Prior research has primarily focused on associated medical problems and skill deficits. This study takes a novel positive psychology approach by examining critical individual characteristics and environmental factors that facilitate exceptional quality of life for people with DS.

Toilet Training in Fragile X Syndrome.

Objective: To characterize bladder and bowel toileting skill acquisition in children with fragile X syndrome and to identify associated demographic, behavioral, and clinical factors.

Methods: Using baseline data from the Fragile X Online Registry With Accessible Research Database (FORWARD), bivariate analyses and logistic regression models were used to identify differences between subjects who were and were not bowel and/or bladder trained by the age of 10 years. Cox proportional hazard models were used to assess the rate of completion of toilet training (TT) as a function of sex and autism spectrum disorder (ASD) diagnosis.
