Cultural Adaptation and Validation of Mullen Scales of Early Learning in Taiwanese children with Autism Spectrum Disorder, Global Developmental Delay, and Typically Developing Children.

Background: The Mullen Scales of Early Learning (MSEL) is a standardized comprehensive developmental assessment tool for children aged 0-68 months. However, few Asia-based studies have explored cultural and linguistic adaptations of the MSEL or investigated its psychometric properties in populations with autism spectrum disorder (ASD).

Aims: This study evaluated the reliability and validity of the MSEL-Taiwan version (MSEL-T) for Taiwanese children with ASD, global developmental delay (GDD), and typical development (TD).

Multidimensional Development and Adaptive Behavioral Functioning in Younger and Older Children With Rett Syndrome.

Objective: The purpose of this study was to examine clinical severity, multidimensional development, and adaptive behavioral functioning in younger and older children with Rett syndrome (RTT) in the pseudostationary stage (stage III).

Methods: Fourteen younger (≤10 years of age) and 15 older (11-18 years of age) children with confirmed stage III RTT (assigned to young-RTT and old-RTT groups, respectively) participated in this study. Clinical severity was determined using the Clinical Severity Score (CSS) scale for RTT.

Relationship Between Motor Skills and Language Abilities in Children With Autism Spectrum Disorder.

Objectives: Few studies have examined the relationship between language abilities and specific motor skills in toddlers with autism spectrum disorder (ASD). The aim of this study was to compare the relationship of receptive language (RL) and expressive language (EL) abilities with motor functioning in toddlers with ASD aged 24 to 36 months and their peers with typical development (TD). Furthermore, the study compared multidimensional motor functioning in toddlers with ASD with delayed RL and EL development and toddlers with ASD and typical RL and EL development.
