This study examined differences in acoustic characteristics of infant cries in a sample of babies at risk for autism and a low-risk comparison group. Cry samples derived from vocal recordings of 6-month-old infants at risk for autism spectrum disorder (ASD; n = 21) and low-risk infants (n = 18) were subjected to acoustic analyses using analysis software designed for this purpose. Cries were categorized as either pain-related or non-pain-related based on videotape coding. At-risk infants produced pain-related cries with higher and more variable fundamental frequency (F0) than low-risk infants. At-risk infants later classified with ASD at 36 months had among the highest F0 values for both types of cries and produced cries that were more poorly phonated than those of nonautistic infants, reflecting cries that were less likely to be produced in a voiced mode. These results provide preliminary evidence that disruptions in cry acoustics may be part of an atypical vocal signature of autism in early life.

School professionals who work with students with autism spectrum disorder (ASD) play a significant role in the academic experiences of these students, but some evidence suggests that teachers of students with ASD experience a high risk of burnout. Research has begun to examine factors that ameliorate or prevent teacher burnout, including teacher training and teacher self-efficacy, or teachers' beliefs regarding their abilities to bring about positive outcomes for their students. The present study examined variables associated with the self-efficacy of school professionals for working with students with ASD, including knowledge about ASD, prior experience working with students with ASD, and prior training in ASD and evidence-based practices. A second goal of the present study was to investigate the impact of training on ASD and evidence-based practices on school professionals' knowledge and self-efficacy related to working with students with ASD. In particular, the participants received training on the Prevent-Teach-Reinforce model. Results of the present study suggested the importance of training to school professionals' self-efficacy, highlighting the need for continued efforts to provide quality training to individuals who work with students with ASD.

The present study was a multisite randomized clinical trial assessing the effects of adding a cognitive-behavioral intervention to positive behavior support (PBS). Fifty-four families who met the criteria of (a) having a child with a developmental disability, (b) whose child displayed serious challenging behavior (e.g., aggression, self-injury, tantrums), and (c) who scored high on a measure of parental pessimism were randomly assigned to either PBS intervention or a combination of PBS and optimism training for parents (positive family intervention [PFI]). A manualized approach to both interventions was used for eight weekly individual sessions. Both groups improved in scores of parental pessimism as well as on standardized measures and direct observations of child challenging behavior. The PFI intervention resulted in significantly improved scores on the General Maladaptive Index of the Scales of Independent Behavior-Revised when compared with the PBS alone group. No differences in attrition were observed across the two different approaches. Importantly, significant improvements in child behavior at home were achieved through a clinic-based approach. Implications for working with families who may be less likely to benefit from parent training are discussed.

These results suggest: (i) that the global measures usually employed may not be appropriate for demonstrating specific relationships between symptoms and executive functions and (ii) that it is necessary to take into account the interactions between positive symptoms as well as with other factors to reveal these relationships.
