This study evaluates an intervention targeting social-communication and play skills (Advancing Social-communication And Play; ASAP) implemented by school staff in a public preschool setting. With increases in enrollment of children with autism spectrum disorder (ASD) in school systems, establishing the effectiveness and feasibility of interventions implemented in school settings is important. In clinical settings, interventions targeting social-communication and play behaviors have increased these skills and impacted later language abilities. Results of this single-case design study indicated the ASAP intervention had a positive impact on social-communication and play skills for three preschoolers with ASD. All participants showed either increases in frequency or more stability in targeted behaviors. Social validity results provide additional support for the use of ASAP with preschoolers with ASD.

While early diagnosis of autism spectrum disorders (ASD) is essential for ensuring timely access to early intervention services, there is limited existing literature investigating factors that delay this diagnosis. This population-based cohort study explored the age at which children in Nova Scotia, Canada, are diagnosed with ASDs and the factors associated with this age. Children diagnosed with an ASD between January 1992 and December 2005 were identified from a cohort of live births in the province between 1990 and 2002. Demographic and clinical variables were extracted from population-based perinatal and administrative health databases and evaluated as predictors of age at ASD diagnosis. Of 122,759 live births, 884 cases of ASDs were identified during the study period. The median age at diagnosis within the cohort was 4.6 years. In adjusted linear regression analysis, a one year increase in maternal age at delivery was associated with a 0.06 decrease in age at ASD diagnosis (p = .0007). Children who were residents of Halifax County received their diagnoses 0.52 years later than residents of other counties (p = .0054). A diagnosis of attention-deficit/hyperactivity disorder (ADHD) was associated with a 1.29-year increase in age at diagnosis (p < .0001). These results suggest that potential exists for improving early detection of ASDs in the province. Future research in this field has the potential to contribute to our understanding of the causal pathways linking the demographic and clinical variables we have identified and the age at diagnosis of ASDs.

Raising a child with an Autism Spectrum Disorder (ASD) presents significant challenges for parents that potentially have a impact on their health and wellbeing. The current study examined the extent to which parents experience fatigue and its relationship to other aspects of wellbeing and parenting. Fifty mothers of children with an ASD aged 2-5 years participated in the study. Compared with mothers of typically developing children, mothers of children with an ASD reported significantly higher fatigue, with overall scores in the moderate range. Factors associated with high levels of fatigue were poor maternal sleep quality, a high need for social support and poor quality of physical activity. Fatigue was also significantly related to other aspects of wellbeing, including stress, anxiety and depression, and lower parenting efficacy and satisfaction. The need for interventions to specifically target parental fatigue and its impact on families affected by ASDs both in the short and long term is clearly indicated.

Objective: This article examines the form and function of spontaneous communication and outcome predictors in nonverbal children with autism following classroom-based intervention (Picture Exchange Communication System [PECS] training). Method: 84 children from 15 schools participated in a randomized controlled trial (RCT) of PECS (P. Howlin, R. K. Gordon, G. Pasco, A. Wade, & T. Charman, 2007). They were aged 4-10 years (73 boys). Primary outcome measure was naturalistic observation of communication in the classroom. Multilevel Poisson regression was used to test for intervention effects and outcome predictors. Results: Spontaneous communication using picture cards, speech, or both increased significantly following training (rate ratio [RR] =1.90, 95% CI [1.46, 2.48], p < .001; RR = 1.77, 95% CI [1.35, 2.32], p < .001; RR = 3.74, 95% CI [2.19, 6.37], p < .001, respectively). Spontaneous communication to request objects significantly increased (RR = 2.17, 95% CI [1.75, 2.68], p < .001), but spontaneous requesting for social purposes did not (RR = 1.34, 95% CI [0.83, 2.18], p = .237). Only the effect on spontaneous speech persisted by follow-up (9 months later). Less severe baseline autism symptomatology (lower Autism Diagnosis Observation Schedule [ADOS] score; C. Lord et al., 2000) was associated with greater increase in spontaneous speech (RR = 0.90, 95% CI [0.83, 0.98], p = .011) and less severe baseline expressive language impairment (lower ADOS item A1 score), with larger increases in spontaneous use of speech and pictures together (RR = 0.62, 95% CI [0.44, 0.88], p = .008). Conclusion: Overall, PECS appeared to enhance children’s spontaneous communication for instrumental requesting using pictures, speech, or a combination of both. Some effects of training were moderated by baseline factors. For example, PECS appears to have increased spontaneous speech in children who could talk a little at baseline.
