Classification of intellectual disability according to domains of adaptive functioning and between-domains discrepancy in adults with epilepsy

Developmental Functioning of Infants and Toddlers with Neurodevelopmental Disorders

PURPOSE

The current study aimed to investigate developmental functioning in infants and toddlers with autism spectrum disorder (ASD), seizures, cerebral palsy (CP), and atypical development.

METHODS

An ANOVA was utilized to investigate the differences between neurodevelopmental group on BDI-2 developmental quotient and a MANOVA was used to investigate the differences between the groups and five developmental domains.

RESULTS

The results indicated statistically significant differences in overall developmental functioning and each subdomain of the BDI-2.

DISCUSSION

These findings provide the basis for further research to investigate comorbidities of the three neurodevelopmental disorders and parse out the impact of intellectual disability (ID).

Intellectual Disability Profiles, Quality of Life and Maladaptive Behavior in Deaf Adults: An Exploratory Study

Individuals who are prelingually deaf and have intellectual disabilities experience great challenges in their language, cognitive and social development, leading to heterogeneous profiles of intellectual and adaptive functioning. The present study describes these profiles, paying particular attention to domain discrepancies, and explores their associations with quality of life and maladaptive behavior. Twenty-nine adults with prelingual deafness (31% female) and mild intellectual functioning deficits (mean IQ = 67.3, SD = 6.5) were administered the Vineland Adaptive Behavior Scales-II (VABS-II) and an adapted sign language version of a quality of life scale (EUROHIS-QOL 8). Intellectual disability domain discrepancies were characterized as at least one standard deviation difference between the social domain and IQ and the practical domain and IQ, and a significant difference, according to the VABS-II manual, between the social and practical domains. Domain discrepancies were found between intellectual functioning and both the practical (58.6%) and social domain (65.5%). A discrepancy between intellectual and social functioning was significantly associated with a higher level of internalizing maladaptive behavior (T = 1.89, p < 0.05). The heterogeneous profiles highlight the importance of comprehensive assessments for adequate service provision.
