Autistic people experience high rates of mental health problems. A tendency towards behavioural repetition in autistic individuals could contribute to repetitive negative thinking, which is a transdiagnostic risk factor for mental health problems. Our research aimed to add to the literature by using transdiagnostic measures of both mental health…

Shared family meals are associated with family functioning and thought to protect against disordered eating in families with neurotypical children. Limited research, however, has examined the mealtime structure or experience in families with children with autism (Autism spectrum condition) and/or attention deficit hyperactivity disorder, despite…

Rates of self-injurious thoughts and behaviors are elevated among autistic youth, yet research is limited to caregiver report or single-item questionnaires. Investigation of specific suicidal thoughts, triggers, and disclosure is needed to improve risk assessment and interventions. The current study characterized self-injurious thoughts and…

Autistic meltdowns have been explored from the perspectives of parents, but there is a paucity of research on the experience of meltdowns from the autistic perspective. Little is known about how adults experience these events. In this descriptive phenomenological study, we conducted online interviews with 32 autistic adults on the experience of…

Many autistic children have co-occurring behavioural problems influencing core autism symptomology potentially relevant for intervention planning. Parental Expressed Emotion -- reflecting critical, hostile and overprotective comments -- contributes to understanding and predicting behaviour in autistic school-aged children, adolescents and adults…

This study aimed to investigate the feasibility, acceptability, and preliminary effects of an acceptance and commitment therapy (ACT)-based parenting program for parents of autistic children. A pilot randomized controlled trial (RCT) was conducted, with 40 parents randomly assigned to either the eight-session ACT-based parenting program or usual…

Many autistic individuals camouflage socially atypical behaviours. Evidence suggests autistic females camouflage more than autistic males. Although camouflaging may confer some benefits, it is also associated with negative outcomes including poorer mental health and well-being. Those with high autistic traits but no clinical diagnosis are not…

Associations between parent critical attitudes (a component of the Expressed Emotion construct) and behavior problems have been relatively well established in adolescents and young adults with autism spectrum disorder, but use of systems adapted for children with autism spectrum disorder and additional investigations with younger samples are…

Cross-sectional research has demonstrated the overrepresentation of gender dysphoria in children and adults with autism spectrum disorder. However, the predictors and underlying mechanisms of this co-occurrence remain unclear. This follow-up study aimed to explore baseline (childhood/adolescence) predictors for the follow-up (adulthood)…

Posttraumatic growth theory posits that when life circumstances are perceived as stressful, secondary appraisal processes can be recruited in ways to facilitate both coping efforts and personal growth. Using a mixed-methods approach, we found mothers' most challenging experiences involved child behavior (e.g. aggression, communication, and social…

Emotional reactivity (e.g. explosive outbursts, tantrums) is a common but understudied challenge for individuals with autism spectrum disorder. Prior research has relied primarily on questionnaire data or observations of very young children. The current study coded emotional reactivity and recovery during a series of standardized frustration tasks…

Autism spectrum disorder is associated with high rates of co-occurring health conditions. While elevated prescription rates of psychotropic medications have been reported in the United Kingdom and the United States, there is a paucity of research investigating clinical and prescribing practices in Australia. This study describes the problems…

Publicly funded mental health programs play a significant role in serving children with autism spectrum disorder. Understanding patterns of psychiatric comorbidity for this population within mental health settings is important to implement appropriately tailored interventions. This study (1) describes patterns of psychiatric comorbidity in…

This study (a) examined the role of anger rumination as a mediator of the relation between social anxiety and the experience of anger, hostility, and aggression, in the general population, and (b) evaluated the degree to which the presence of autism spectrum disorder characteristics moderates the indirect influence of anger rumination. We then…

This study aims to evaluate the long-term outcome of Children's Friendship Training, a parent-assisted social skills intervention for children. Prior research has shown Children's Friendship Training to be superior to wait-list control with maintenance of gains at 3-month follow-up. Participants were families of children diagnosed with autism…
