Deficits in question-asking are common in children with autism spectrum disorder (ASD). Furthermore, their opportunities to self-initiate questions are often hindered by directive behavior of their conversation partners. This study assessed the effectiveness of staff training in pivotal response treatment (PRT) on staff member-created…

In a non-selected sample of children with Neurofibromatosis type 1 (NF1) the prevalence rate of autism spectrum disorder (ASD) and predictive value of an observational (ADOS)--and questionnaire-based screening instrument were assessed. Complete data was available for 128 children. The prevalence rate for clinical ASD was 10.9%, which is clearly…

To gain further insight into psychosexual functioning, including behaviors, intrapersonal and interpersonal aspects, in adolescents with Autism Spectrum Disorder (ASD), comprehensive, multi-informant measures are needed. This study describes (1) the development of a new measure of psychosexual functioning in both parent- and self-reports (Teen…

Purpose of this quasi-experimental trial was to investigate the effect of Pivotal response treatment (PRT) versus treatment as usual (TAU) on autism symptoms. Children with autism spectrum disorder (ASD), aged 3-8 years, received either PRT (n = 11) or TAU (n = 13). Primary outcome measure was the total score on the Autism Diagnostic Observation…

Juveniles who have committed a sexual offense (JSOs) are thought to have abnormal sexual development, as well as increased ASD symptoms. In the current study, sexual development and behavior, as well as stability of ASD-like symptoms were assessed in a sample of 44 male JSOs (mean age 24.7 ± 1.5 years) 8 years after their sexual offence. JSOs…

A social skills training (SST) for high-functioning children with autism spectrum disorders (ASD) was evaluated in an outpatient setting using a combined between- and within-subject design in which SST and a waiting list condition were compared. According to parents and teachers, the SST produced greater improvement of social skills than the…

A study of 10 children (ages 3-6) with pervasive developmental disorders investigated the interrater reliability of the Psychoeducational Profile (PEP). Results show good interrater reliability for the developmental items, indicating that the PEP can be used to evaluate progress in development of children with pervasive developmental disorders.…

A study examined the social cognition of 20 Dutch children (ages 8-18) with autism, 20 with pervasive developmental disorder not otherwise specified, 20 with psychiatric disorders, and 20 typical children. Theory of mind and emotion recognition functioning proved to be correlated and less integrated in children with autistic spectrum disorders.…

A study of 20 children (ages 3-6) with autism and 20 children with pervasive developmental disorders (PDD) examined the validity of a Dutch version of the revised Psychoeducational Profile (PEP-R). No differences were found on the PEP-R developmental subscales, but on the pathology subscales children with autism showed more severe behavior than…

Seventy-two children (ages 23-148 months) referred to an autism center in the Netherlands were administered the Psychoeducational Profile (PEP) and the Handicaps Behaviour and Skills Schedule (HBS). The correlation between the two instruments was higher than expected, and internal consistency of the subscales of the PEP and the HBS was…
