This study examined age trends in anxious and depressive symptoms, from older adolescence to old age, and explored the association between anxious and depressive symptoms with gender, ASD severity, and socio-economic factors. Two hundred and fifty-five individuals with ASD (151 males, M[subscript age] = 33.52 years, SD[subscript age] = 14.98) took…

Although informed consent is critical for all research, there is increased ethical responsibility as individuals with intellectual or developmental disabilities (IDD) become the focus of more clinical trials. This study examined decisional capacity for informed consent to clinical trials in individuals with fragile X syndrome (FXS). Participants…

Ganglmayer, Kerstin; Schuwerk, Tobias; Sodian, Beate; Paulus, Markus – Journal of Autism and Developmental Disorders, 2020
An action's end state can be anticipated by considering the agent's goal, or simply by projecting the movement trajectory. Theories suggest that individuals with autism spectrum condition (ASC) have difficulties anticipating other's goal-directed actions, caused by an impairment using prior information. We examined whether children, adolescents…

This study examined trajectories of daily living skills, behavior problems, body mass index (BMI), and health conditions spanning nearly a decade in adolescents and adults with fragile X syndrome (N = 134; age range at study end = 19-49 years), examining influences of sex and autism spectrum disorder (ASD) symptoms. Hierarchical linear modeling…

Umesawa, Yumi; Matsushima, Kanae; Atsumi, Takeshi; Kato, Toshihiro; Fukatsu, Reiko; Wada, Makoto; Ide, Masakazu – Journal of Autism and Developmental Disorders, 2020
Several motor disabilities accompanied with autism spectrum disorder (ASD) are widely known despite limited reports of underlying neural mechanisms. Gamma-aminobutyric acid (GABA) levels in the motor-related cortical areas modulate several motor performances in healthy participants. We hypothesized that abnormal GABA concentrations in the primary…

Jager-Hyman, Shari; Maddox, Brenna B.; Crabbe, Samantha R.; Mandell, David S. – Journal of Autism and Developmental Disorders, 2020
Autistic individuals experience elevated risk for suicide ideation, attempts, and deaths. Little is known about how clinicians assess risk or intervene with suicidal autistic individuals. We surveyed 121 clinicians about use of suicide prevention practices with autistic and non-autistic clients. Clinicians reported greater self-efficacy in…

Boland, Kelly M.; Stichter, Janine P.; Beversdorf, David Q.; Christ, Shawn E. – Journal of Autism and Developmental Disorders, 2019
Recent research has documented impaired ability to resist interference from visual distractors in individuals with autism spectrum disorder (ASD) and suggests that this phenomenon may be more pronounced in young versus older children (Christ et al., "Neuropsychology" 25(6):690-701, 2011). The present study extends previous findings by…

Ezell, Jordan; Hogan, Abigail; Fairchild, Amanda; Hills, Kimberly; Klusek, Jessica; Abbeduto, Leonard; Roberts, Jane – Journal of Autism and Developmental Disorders, 2019
Anxiety disorders affect ~ 15-20% of youths without neurodevelopmental disorders, with persons having autism spectrum disorder (ASD) and fragile X syndrome (FXS) at elevated risk for anxiety disorders. Few studies have compared rates and predictors of anxiety disorders in adolescents with FXS or ASD. This study directly compares rates, predictors,…

Schaller, Ulrich Max; Biscaldi, Monica; Fangmeier, Thomas; Tebartz van Elst, Ludger; Rauh, Reinhold – Journal of Autism and Developmental Disorders, 2019
Using a schema-theoretical perspective in the field of moral cognition, we assessed response behavior of adolescent (n = 15) and adult (n = 22) individuals with Autism Spectrum Disorder (ASD) in comparison with adolescent (n = 22) and adult (n = 22) neurotypically developed controls. We conceptualized the Intuitive Moral Reasoning Test--in five…

Platos, Mateusz; Wojaczek, Kinga – Journal of Autism and Developmental Disorders, 2018
Peer-mediated intervention (PMI) is most commonly defined as a treatment approach that engages typically developing peers to teach children with autism spectrum disorders (ASD) social skills and increase their social interactions, mainly in a school setting. In this letter, we address the limitations of such understanding of PMI and review the…

Martínez-González, A. E.; Piqueras, J. A. – Journal of Autism and Developmental Disorders, 2018
Restricted and repetitive behavior (RRB) is one of the two key diagnostic features of autism spectrum disorder (ASD). DSM-5 highlights the importance of severity-based diagnostic modifiers assigned on the basis of intensity of needed supports. Therefore, there is a need for available measures that assess the severity of RRB. The repetitive…
