Recently, there has been heightened interest in suggestions of enhanced visual acuity in autism spectrum disorders (ASD) which was sparked by evidence that was later accepted to be methodologically flawed. However, a recent study that claimed children with ASD have enhanced visual acuity (Brosnan et al. in J Autism Dev Disord 42:2491-2497, 2012) repeated a critical methodological flaw by using an inappropriate viewing distance for a computerised acuity test, placing the findings in doubt. We examined visual acuity in 31 children with ASD and 33 controls using the 2 m 2000 Series Revised Early Treatment Diabetic Retinopathy Study chart placed at twice the conventional distance to better evaluate possible enhanced acuity. Children with ASD did not demonstrate superior acuity. The current findings strengthen the argument that reports of enhanced acuity in ASD are due to methodological flaws and challenges the reported association between visual acuity and systemising type behaviours.
There is a paucity of diagnostic instruments for adults with autism spectrum disorder (ASD). This study evaluates the psychometric properties of the Swedish version of the Ritvo Autism and Asperger Diagnostic Scale-Revised (RAADS-R), an 80-item self-rating scale designed to assist clinicians diagnosing ASD in adults. It was administered to 75 adults with ASD and 197 comparison cases. Also, a subset completed the Autism Spectrum Quotient (AQ). Three out of four subscales had high internal consistency. Sensitivity was 91% and specificity was 93%. The ASD subjects had significantly higher mean scores on all subscales. ASD females had higher scores than ASD males on the sensory motor subscale, a dimension not included in the AQ. RAADS-R showed promising test re-test reliability.
The broad autism phenotype (BAP) is a set of characteristics often observed in typically developing people with a genetic load for autism, such as parents of autistic children. The Broad Autism Phenotypic Questionnaire (BAPQ) is a 36-item questionnaire developed to identify the BAP in first-degree relatives of autistic people. We translated the BAPQ into Swedish and examined its psychometric properties in a Swedish sample consisting of 45 parents of children with ASC and 74 parents of non-autistic children. We found support for the original 3-factor structure (aloof, pragmatic language and rigid), good internal consistency and convergent validity with the Autism Quotient. Thus, the Swedish BAPQ exhibits acceptable psychometric properties and may be useful for assessing the BAP in non-clinical populations.
The aim of the study was to describe the occupational transition process to upper secondary school, further education and/or work, and to discover what support influences the process from the perspectives of young adults with Asperger’s disorder (AS) or attention deficit/hyperactivity disorder (ADHD). This qualitative study comprised semi-structured interviews with 15 young adults with AS or ADHD, eight men and seven women (aged 20 to 29 years). Most of the participants were attending community-based day centres at local businesses. Analysis identified three different occupational transition pathways following compulsory school. Support influencing the occupational transition process included: occupational transition preparation in compulsory school, practical work experience in a safe environment, and support beyond the workplace. The overall understanding shows that the occupational transition process was a longitudinal one starting as early as in middle school, and continuing until the young adults with AS and ADHD obtained and were able to remain in employment or further education. Support from community-based day centres was described both as an important step towards finding employment in the regular labour market in which participants could develop practical work experience, and as being too far away from the regular labour market.
The symptomatology of autism spectrum disorder (ASD) can make driving risky, but little is known about the on-road driving behaviour of individuals with ASD. This study assessed and compared the on-road driving performance of drivers with and without ASD, and explored how the symptomatology of ASD hinders or facilitates on-road driving performance. Sixteen drivers with ASD and 21 typically-developed drivers participated in the study. Drivers with ASD underperformed in vehicle manoeuvring, especially at left-turns, right-turns and pedestrian crossings. However, drivers with ASD outperformed the TD group in aspects related to rule-following such as using the indicator at roundabouts and checking for cross-traffic when approaching intersections. Drivers with ASD in the current study presented with a range of capabilities and weaknesses during driving.
A process evaluation was conducted to determine the effectiveness, usability, and barriers and facilitators related to the Better OutcOmes amp; Successful Transitions for Autism (BOOST-A (TM)), an online transition planning program. Adolescents on the autism spectrum (n = 33) and their parents (n = 39) provided feedback via an online questionnaire. Of these, 13 participants were interviewed to gain in-depth information about their experiences. Data were analyzed using descriptive statistics and thematic analysis. Four themes were identified: (i) taking action to overcome inertia, (ii) new insights that led to clear plans for the future, (iii) adolescent empowerment through strengths focus, and (iv) having a champion to guide the way. The process evaluation revealed why BOOST-A (TM) was beneficial to some participants more than others. Trial registration #ACTRN12615000119594.
This paper reports on the effect of using an interactive and child-initiatedmicrocomputer program (Alpha) when teaching three groups of childrenfN = 30) reading and communications skills: (a) 11 children with autism fMchronological age, CA = 9:4 years), (b) 9 children with mixed handicaps(M CA = 13:1), and (c) 10 normal preschool children (M CA = 6:4 years).Their mental age varied from 5:8 years to 6:9 years and all children receivedcomputer instruction supplementary to their regular reading and writing activities. Tests of reading and phonological development were carried out atthe onset of the training (Start), at the end (Post I), and at a follow-upevaluation (Post 2). In addition, video observations of the childrens' verbaland nonverbal communication were added at Start and Post I. The childrenwith autism increased both their word reading and their phonologicalawareness through the use of the Alpha program. Clearly significant gains wereobserved during the intervention, but none during the follow-up period. Asimilar but weaker pattern is observed for the children with mixed handicaps.In contrast, the normal preschool children increased their scores regardless ofthe program. Analyses of the children's classroom behavior indicate that theintervention succeeded in stimulating verbal expressions among the childrenwith autism and mixed handicap. A significant increase in enjoyment was alsonoted for the children with autism. It is concluded that the intervention witha motivating multimedia program might stimulate reading and communicationin children with various developmental disabilities, but that such interventionsmust be individually based and include both detailed planning and monitoringfrom teachers, and parents, as well as from clinicians in charge.
As postsecondary outcomes of adolescents with Autism Spectrum Disorder (ASD) are poor, there is a need for programs that aim to improve employment and education outcomes. This study employed a grounded theory approach to explore the key factors contributing to successful work placement experience and the perceived benefits of these placements from the perspective of adolescents with ASD (n=5), their parents (n=6) and employers (n=6). Key factors contributing to success include preparing for the workplace, harnessing strengths and interests and developing work related skills, while the benefits include insight into the workplace, recognising and realising potential, working as a team and the pathway ahead. The findings articulate a framework which could underpin future transition interventions for adolescents with ASD.
Sensory processing difficulties affect the development of sensorimotor skills in individuals with autism spectrum disorder (ASD). However, the effect of sensory information on postural control is unclear in the ASD adult population. The present study examined the effect of visual information on postural control as well as the attentional demands associated with postural control in fourteen adults with ASD and seventeen typically developed adults. The results showed that postural sway and attention demands of postural control were larger in adults with ASD than in typically developed adults. These findings indicate that visual processing used for postural control may be different in adults with ASD. Further research in visual field processing and visual motion processing may elucidate these sensorimotor differences.
Visual information is crucial for postural control. Visual processing in children with autism spectrum disorder (ASD) was hypothesized to be less efficient and thus they would display a less stable standing posture than typically developing children. The present study compared the static standing responses and attentional demands of 15 children with ASD and 18 control participants in conditions of eyes open and eyes closed. The results showed that postural responses and attention invested in standing were similar between the participant groups in the two visual conditions. Both groups displayed a more stable posture when their eyes were open in comparison to eyes closed. The finding suggests that normal postural control development could occur in children with ASD.
This study aimed to examine the influence of differences in household status on the parental stress, coping, time use and quality of life (QoL) among mothers of children with autism spectrum disorders. Forty-three single and 164 coupled mothers completed the survey. Data were analysed using multivariate logistic regression. We found that single mothers were 1.05 times more likely to report lower levels of environmental QoL. Whilst they were 1.73 times more likely to use acceptance coping style, this association did not persist after adjusting for total number of children, household income and employment status. There was no difference in time use and stress between these mothers. Possible environmental issues for single mothers and implications for future research are discussed.
This exploratory randomised controlled trial tested the effectiveness of a tablet-based information communication technology early intervention application to augment existing therapy with the aim of improving visual motor, imitation, language and social skills in young children with ASD who reside in regional areas. Fifty-nine participants were recruited and randomised to either a therapy-as-usual group or intervention group. With the exception of the expressive language subscale on the Mullen Scales of Early Learning, no significant between-group differences were recorded for visual motor, imitation, receptive language and social skills of participants between baseline and post-intervention. When all participants were pooled and measured over time, improvements were shown in receptive and pragmatic language and social skills; these gains were maintained, thus suggesting skill acquisition.
A randomised controlled trial evaluated the effectiveness of the Integrated Employment Success Tool (IEST (TM)) in improving employers self-efficacy in modifying the workplace for individuals on the autism spectrum. Employers (N = 84) were randomised to the IEST (TM) or support as usual groups. Measurements of self-efficacy, knowledge and attitudes towards disability in the workplace were obtained at baseline and post-test. Results revealed a significant improvement in self-efficacy within the IEST (TM) group between baseline and post-test (p = 0.016). At post-test, there were no significant differences between groups in relation to self-efficacy in implementing autism-specific workplace modifications and employer attitudes towards disability in the workplace. Given the lack of significant outcomes, further research is needed to determine the effectiveness of the IEST (TM) for employers.Trial registration: Australian New Zealand Clinical Trials Registry #ACTRN12614000771651, registered 21/7/2014.

Dyadic coping strategies may play a pivotal role in relationship satisfaction and explain why some couples adapt positively to the challenges associated with raising a child with ASD and others do not. Survey data from 127 caregivers of a child with ASD were used in generalized estimating equation analyses to investigate the factors associated with relationship satisfaction, including socio-demographics, parenting stress and dyadic coping. Results showed that over two-thirds of the sample reported satisfaction, which was associated with low parenting stress, increased use of positive and decreased use of negative dyadic coping strategies. Positive dyadic coping was found to have a greater influence than negative dyadic coping, supporting a strengths-based approach to interventions promoting family resilience.
Globally, there are more bilingual speakers than monolingual speakers; however, scant research evidence exists regarding social communication development and outcomes for bilingual children with autism spectrum disorder (ASD). A stronger evidence base will facilitate health professionals and educators providing accurate recommendations regarding language use. This study employed a longitudinal cohort design to compare social and communication skills, at baseline and over 12 months, for 60 monolingual and 60 bilingual children with ASD receiving community based early intervention. We found few differences at intake, and no difference in the magnitude of change over 12 months for this cohort. Findings support the notion that there is no basis on which to discourage home language use with bilingual children with ASD.
