Neural systems predicting long-term outcome in dyslexia.

Individuals with developmental dyslexia vary in their ability to improve reading skills, but the brain basis for improvement remains largely unknown. We performed a prospective, longitudinal study over 2.5 y in children with dyslexia (n = 25) or without dyslexia (n = 20) to discover whether initial behavioral or brain measures, including functional MRI (fMRI) and diffusion tensor imaging (DTI), can predict future long-term reading gains in dyslexia. No behavioral measure, including widely used and standardized reading and language tests, reliably predicted future reading gains in dyslexia. Greater right prefrontal activation during a reading task that demanded phonological awareness and right superior longitudinal fasciculus (including arcuate fasciculus) white-matter organization significantly predicted future reading gains in dyslexia. Multivariate pattern analysis (MVPA) of these two brain measures, using linear support vector machine (SVM) and cross-validation, predicted significantly above chance (72% accuracy) which particular child would or would not improve reading skills (behavioral measures were at chance). MVPA of whole-brain activation pattern during phonological processing predicted which children with dyslexia would improve reading skills 2.5 y later with >90% accuracy. These findings identify right prefrontal brain mechanisms that may be critical for reading improvement in dyslexia and that may differ from typical reading development. Brain measures that predict future behavioral outcomes (neuroprognosis) may be more accurate, in some cases, than available behavioral measures.

A Randomized Controlled Trial to Improve Social Skills in Young Adults with Autism Spectrum Disorder: The UCLA PEERS(®) Program.

Research suggests that impaired social skills are often the most significant challenge for those with autism spectrum disorder (ASD), yet few evidence-based social skills interventions exist for adults on the spectrum. This replication trial tested the effectiveness of PEERS, a caregiver-assisted social skills program for high-functioning young adults with ASD. Using a randomized controlled design, 22 young adults 18-24 years of age were randomly assigned to a treatment (n = 12) or delayed treatment control (n = 10) group. Results revealed that the treatment group improved significantly in overall social skills, frequency of social engagement, and social skills knowledge, and significantly reduced ASD symptoms related to social responsiveness following PEERS. Most treatment gains were maintained at a 16-week follow-up assessment with new improvements observed.

Predicting treatment success in social skills training for adolescents with autism spectrum disorders: the UCLA Program for the Education and Enrichment of Relational Skills.

This study seeks to examine the predictors of positive social skills outcomes from the University of California, Los Angeles Program for the Education and Enrichment of Relational Skills, an evidence-based parent-assisted social skills program for high-functioning middle school and high school adolescents with autism spectrum disorders. The results revealed that adolescents with higher parent-reported baseline social skills and lower self-reported perceived social functioning demonstrated greater improvement in social skills following the intervention.

Social skills training for young adults with high-functioning autism spectrum disorders: a randomized controlled pilot study.

Despite the psychosocial difficulties common among young adults with autism spectrum disorders (ASD), little to no evidence-based social skills interventions exist for this population. Using a randomized controlled trial (RCT) design, the current study tested the effectiveness of an evidence-based, caregiver-assisted social skills intervention known as PEERS for Young Adults with high-functioning young adults with ASD (ages 18-23) using self- and caregiver-report measures. Results revealed that treated young adults reported significantly less loneliness and improved social skills knowledge, while caregivers reported significant improvements in young adults' overall social skills, social responsiveness, empathy, and frequency of get-togethers. Results support the effectiveness of using this caregiver-assisted, manualized intervention for young adults with ASD.

Evidence-based social skills training for adolescents with autism spectrum disorders: the UCLA PEERS program.

The present study examines the efficacy and durability of the PEERS Program, a parent-assisted social skills group intervention for high-functioning adolescents with ASD. Results indicate that teens receiving PEERS significantly improved their social skills knowledge, social responsiveness, and overall social skills in the areas of social communication, social cognition, social awareness, social motivation, assertion, cooperation, and responsibility, while decreasing autistic mannerisms and increasing the frequency of peer interactions. Independent teacher ratings revealed significant improvement in social skills and assertion from pre-test to follow-up assessment. Examination of durability of improvement revealed maintenance of gains in nearly all domains with additional treatment gains at a 14-week follow-up assessment.
