Article Synopsis
  • Individuals with autism spectrum disorder (ASD) react differently to social stressors compared to those with typical development (TD), with physiological responses being influenced by both the social context and time.
  • The study involved 244 children aged 10-13, analyzing their cortisol levels, heart rate, and respiratory sinus arrhythmia before and after engaging in social evaluative tasks and friendly interactions.
  • Results showed that while cortisol and heart rate reactions varied significantly by diagnosis and context, anxiety did not mediate these physiological responses, highlighting the need for tailored approaches to support ASD youth in social situations.

Recent research suggests there may be differences in the social presentations of autistic males and females. Camouflaging is believed to account for some of these differences and executive function (EF) may support compensatory social behaviors. As few studies have explored the role of sex and everyday EF when evaluating specific social difficulties among autistic youth, the present study seeks to address this.

Article Synopsis
  • The study investigates how depressive symptoms develop over time in autistic youth compared to neurotypical (TD) youth during adolescence, a period known for increased mental health issues.
  • Autistic youth showed higher depression scores than their TD peers initially, but their symptoms decreased as they entered middle adolescence and puberty, while TD youth experienced an increase in depression.
  • Limitations of the research include a smaller number of females in the sample and the unique circumstances around the COVID-19 pandemic that could affect the results.

Recent research in autism spectrum disorder (ASD) has suggested a higher prevalence of gender diversity in individuals diagnosed with ASD. Adolescence is a critical period for the consolidation of gender identity, yet the extent to which the experience of gender diversity is stable over adolescence and puberty in autistic youth is poorly understood. The aim of the study was to examine the consistency of gender diversity using the gender diversity screening questionnaire for self- and parent-report of youth (GDSQ-S, GDSQ-P) over a four-year longitudinal study of pubertal development in youth with ASD (N = 140, 36 assigned-female-at birth (AFAB)) and typical development (TD, N = 104, 58 assigned-male-at-birth [AMAB]) and their parents.

Autism spectrum disorder (ASD) is characterized by challenges in social competence that persist in adulthood, yet few treatment options exist. A pilot randomized clinical trial (RCT) of a peer-mediated, theatre-based intervention with established efficacy in youth with ASD was examined in autistic adults. The final sample consisted of forty-seven 18-to-40-year-old participants randomized to the experimental (EXP N = 23) or waitlist control (WLC N = 24) condition.

Background: Puberty is characterized by significant physical, hormonal, and psychological changes, which may be especially challenging for individuals with autism spectrum disorder (ASD). Although the etiology of ASD remains uncertain, studies suggest imbalances in hormones, such as testosterone, may modulate the autism phenotype. While differences in fetal and postnatal testosterone have been reported, there is limited literature regarding testosterone variations during adolescence in ASD.

Prolonged dysregulation of the autonomic nervous system (ANS) may increase propensity for physical or psychiatric illness. The current study examined differences in respiratory sinus arrhythmia (RSA) regulation in 215 adolescents with or without autism spectrum disorder (ASD) at Time 1 (T1; 10-13 years old) and 1 year later (Time 2; T2). Linear mixed effects models demonstrated lower RSA regulation in ASD, and a small interaction effect, showing blunted change in RSA from T1 to T2.

Article Synopsis
  • Gender diversity refers to how individuals express their gender differently than societal expectations based on their assigned sex at birth.
  • Recent research indicates that autistic youth demonstrate higher rates of both Binary and Nonbinary Gender Diversity compared to their typically developing peers.
  • Parents of autistic children report more gender-body incongruence and there are significant links between gender diversity and mental health issues like anxiety and depression, emphasizing the need for better support for these children.

Individuals with autism spectrum disorder (ASD) may demonstrate atypical autonomic (ANS) responses; however, research remains inconsistent. This study examined parasympathetic response during social evaluation in 241 youth (10-13 years) with ASD (n = 138) or typical development (TD; n = 103). Diagnosis, age, pubertal development, and body mass index (BMI) were hypothesized to be associated with ANS function.

In the wake of COVID-19, the world has become a more uncertain environment-a breeding ground for stress and anxiety, especially for individuals with autism spectrum disorder (ASD). The study examined stress, anxiety, and coping in a data-driven, real-time assessment of 122 youth with and without ASD and their parents at the height of the COVID-19 shutdown and three-months later. Standardized measures were administered to ascertain stress and coping explicitly related to the pandemic (RSQ COVID-19-Child [self-report], Adult [self-report from the guardian of youth], Parent [report about child]) and anxiety (STAI-C, STAI-A).

Background: Individuals with autism spectrum disorder (ASD) often experience elevated stress during social interactions and may have difficulty forming and maintaining peer relationships. The autonomic nervous system (ANS) directs physiological changes in the body in response to a number of environmental stimuli, including social encounters. Evidence suggests the flexibility of the ANS response is an important driving factor in shaping social behavior.

Introduction: Humans place high value on how they are socially evaluated by others. The Trier Social Stress Test (TSST) is a well-established measure of social evaluative threat that promotes activation of the hypothalamic pituitary adrenal (HPA) axis and release of cortisol. Higher cortisol responses in typically developing (TD) adolescents are influenced by age and pubertal development especially in later stages.

Camouflaging refers to behavioral adaptations that individuals with autism spectrum disorder (ASD), especially females, use to mask symptoms during social situations. Compensation is a component of camouflaging in which an individual's observed behavior is considerably better than actual ability. The study explored diagnostic, sex-based, and compensatory differences using the Contextual Assessment of Social Skills (CASS).

Children with autism spectrum disorder (ASD) have significant difficulty in social functioning to include engaging in natural play with peers. Many children with ASD exhibit significantly less interactive play and more physiological stress during benign social encounters with same-age peers on a playground. Theatrical role-playing and performance with expert role models may provide a unique opportunity for children with ASD to learn to engage with other children in a safe, supportive environment.

Depression is often associated with dysfunction in the hypothalamic-pituitary-adrenal (HPA) axis and autonomic nervous system (ANS). Individuals with autism spectrum disorder (ASD) may experience physiological dysregulation and psychological comorbidities; however, the extent to which the interactions between these systems predict internalizing symptoms in ASD has not been investigated. The study examined interactions with the HPA axis and ANS in 10-13-year-old children with ASD (n = 41) and typical development (TD; n = 46).

Response to psychological stress can vary based on the extent to which the context is perceived as stressful, especially under different social conditions. The purpose of this preliminary study was to compare physiological stress (cortisol) and regulation (respiratory sinus arrhythmia, RSA) of 10-12 year old children with autism spectrum disorder (ASD, n = 31) or typical development (TD, n = 25) when exposed to two social stress protocols. The extent to which perceived emotion (affect recognition) and anxiety (state and trait) mediate the stress response was also explored.

Social evaluative threat is a potent activator of the hypothalamic-pituitary-adrenocortical (HPA) axis in typically developing (TD) populations. Studies have shown that children and adolescents with autism spectrum disorder (ASD) show a blunted cortisol response to this type of stressor; yet, a previous study in adults with ASD reported a more prototypical stress response. The current study compared 24 adolescents and 17 adults with ASD to investigate a possible developmental lag in autism resulting in a more adaptive stress response to social evaluation with development.

Introduction: The autonomic nervous system (ANS) is involved in regulating social behavior; Autism Spectrum Disorder (ASD) is characterized by alterations in social behavior and reduced physiological response to threat. We hypothesized that adolescents with ASD would show reduced ANS response to social threat.

Methods: Eighteen males with ASD and thirteen males with typical development (TD), ages 12 to 17, completed a social threat paradigm while wearing an impedance cardiography apparatus.
