The predominant models on the emergence and maintenance of stereotypy in individuals with developmental disabilities are based on operant and neurobiological interpretations of the behavior. Although the proponents of the two models maintain largely independent lines of research, operant and neurobiological interpretations of stereotypy are not…

Many children with Autism Spectrum Disorder (ASD) demonstrate challenging behaviors. Since challenging behaviors are obstacles for social development and learning, it is important to determine if and what challenging behaviors are exhibited. Although there are some measures that asses for challenging behaviors, the majority were not specifically…

Lesson starts are transitional events which may cause management problems for teachers. In this study 131 lesson starts of equally many teachers were observed in primary and secondary schools in Finland. The results indicated that, in general, the problems were minimal. However, for various reasons lesson starts were delayed by an average of about…

We evaluated the proportion of individuals with Down syndrome (DS: N = 108) who met criteria for autism spectrum disorder (ASD) on the Social Communication Questionnaire and the severity of ASD-related symptomatology in this group. The proportions of individuals with DS meeting the cut-off for ASD and autism in this sample were 19% and 8%,…

Parenting a child with autism may differentially affect mothers and fathers. Existing studies of mother-father differences often ignore the interdependence of data within families. We investigated gender differences within-families using multilevel linear modeling. Mothers and fathers of children with autism (161 couples) reported on their own…

Theory and evidence suggest the potential value of prodromal intervention for infants at risk of developing autism. We report an initial case series (n = 8) of a parent-mediated, video-aided and interaction-focused intervention with infant siblings of autistic probands, beginning at 8-10 months of age. We outline the theory and evidence base…

Bullying often persists in spite of formal programs targeting this problem. Supportive school and classroom communities enlist brave peers in consoling, encouraging, and befriending victims, which removes the status that fuels bullies. For the past 18 years, this author has worked in multiple children's agencies and schools, studying bullying…

Background: Although prior studies have shown that detained females are marked by significant adverse circumstances, little is known about their adult outcomes. Method: Prospective follow-up study of 184 (80.4% of original sample of 229) detained adolescent females who were reassessed 4.5 SD = 0.6) years later in young adulthood (mean age = 20.0,…

Background: Prior studies exploring gene-environment interactions (GxE) in the development of youth conduct problems (CP) have focused almost exclusively on single-risk experiences, despite research indicating that the presence of other risk factors and or the absence of protective factors can accentuate the influence of a given risk factor on CP.…

Extensive exposure to nonparental child care during the first 4.5 years of life has been demonstrated in some American studies to negatively affect children's socioemotional functioning. Data from 935 preschool children who averaged 54.9 (SD = 3.0) months of age, from Trondheim, Norway were used to examine whether such negative effects, would…

Although treatment acceptability was originally proposed as a critical factor in determining the likelihood that a treatment will be used with integrity, more contemporary findings suggest that whether something is likely to be adopted into routine practice is dependent on the complex interplay among a number of different factors. The Usage Rating…

In a 3-tiered, prevention-oriented framework, Tier II (secondary, targeted) interventions are designed for students whose problem behaviors have not responded to Tier I but are not severe enough to warrant an individualized Tier III intervention. Tier II interventions are implemented similarly across students receiving the intervention and can be…

22q11.2 deletion syndrome (22q11DS) has a complex phenotype with more than 180 characteristics, including cardiac anomalies, cleft palate, intellectual disabilities, a typical facial morphology, and mental health problems. However, the variable phenotype makes it difficult to predict clinical outcome, such as the high prevalence of psychosis among…

Opinions of parenting programs mostly have been obtained from mothers. Because mothers and fathers' interactions with children differ, gathering data from both parents regarding behavior modification and parenting programs is necessary. This project was part of a larger study and compared mothers and fathers' acceptability of Parent-Child…

The purpose of this article is to provide tools for preschool professionals to plan for transitions between daily routines, to identify challenging transitions during the day, and to offer strategies to support transitions in classrooms to prevent challenging behaviors from occurring due to frequent changes. Specifically, the authors answer three…
