Functional analysis of insistence on sameness in an 11-year old boy with Asperger syndrome

Association between Mothers' Emotional Problems and Autistic Children's Behavioral Problems: The Moderating Effect of Parenting Style

Mothers' emotional problems are associated with autistic children's behavioral problems. We aim to test whether parenting styles moderate associations between mothers' mood symptoms and autistic children's behavioral problems. A sample of 80 mother-autistic child dyads were enrolled at three rehabilitation facilities in Guangzhou, China. The Social Communication Questionnaire (SCQ) and the Strengths and Difficulties Questionnaire (SDQ) were used to collect the autistic symptoms and behavioral problems of the children. Mothers' depression and anxiety symptoms were measured using the Patient Health Questionnaire 9 (PHQ-9) and the General Anxiety Disorder 7-item (GAD-7) scale, respectively, and parenting styles were measured using the Parental Behavior Inventory (PBI). Our results show that mothers' anxiety symptoms were negatively associated with their children's prosocial behavior scores (β = -0.26, p < 0.05) but positively related to their social interaction scores (β = 0.31, p < 0.05). Supportive/engaged parenting styles positively moderated the effects of mothers' anxiety symptoms on their prosocial behavior score (β = 0.23, p = 0.026), whereas hostile/coercive parenting styles had a negative moderation (β = -0.23, p = 0.03). Moreover, hostile/coercive parenting styles positivity moderated the effects of mothers' anxiety symptoms on social interaction problems (β= 0.24, p < 0.05). The findings highlight, where mothers adopted a hostile/coercive parenting style while experiencing high anxiety, their autistic child may have more serious behavioral problems.

Does the gender matter?: Anxiety symptoms and emotion dysregulation in adults with autism and intellectual disabilities

Research shows high rates of anxious symptoms in people autistic spectrum disorder (ASD). Finding factors related to the development of anxiety in ASD is necessary. Emotion regulation (ER) is associated with anxiety in ASD. Moreover, some studies find higher rates of anxiety in women with ASD. A total of 121 adults (M = 35.46 years, SD = 9.46) with ASD and intellectual disabilities were evaluated to verify moderating role of gender and mediating role of ER. A moderated mediation analysis supported the moderated role of gender in the relationship mediated by emotional dysregulation between ASD and anxiety. These findings suggest that interventions designed to prevent or reduce anxiety symptoms in women with ASD should include among their goals emotional regulation. LAY SUMMARY: If we want to reduce or prevent anxiety symptoms in women with ASD we must work on emotional regulation.

Proximate and ultimate causes of ritual behavior

Ritual behaviour, intended as a specific, repetitive and rigid form of action flow, appears both in social and non-social environmental contexts, representing an ubiquitous phenomenon in animal life including human individuals and cultures. The purpose of this contribution is to investigate an evolutionary continuum in proximate and ultimate causes of ritual behavior. A phylogenetic homology in proximal mechanisms can be found, based on the repetition of genetically programmed and/or epigenetically acquired action patterns of behavior. As far as its adaptive significance, ethological comparative studies show that the tendency to ritualization is driven by the unpredictability of social or ecological environmental stimuli. In this perspective, rituals may have a "homeostatic" function over unpredictable environments, as further highlighted by psychopathological compulsions. In humans, a circular loop may have occurred among ritual practices and symbolic activity to deal with a novel culturally-mediated world. However, we suggest that the compulsion to action patterns repetition, typical of all rituals, has a genetically inborn motor foundation, thus precognitive and pre-symbolic. Rooted in such phylogenetically conserved motor structure (proximate causes), the evolution of cognitive and symbolic capacities have generated the complexity of human rituals, though maintaining the original adaptive function (ultimate causes) to cope with unpredictable environments.

Insights from perceptual, sensory, and motor functioning in autism and cerebellar primary disturbances: Are there reliable markers for these disorders?

The contribution of cerebellar circuitry alterations in the pathophysiology of Autism Spectrum Disorder (ASD) has been widely investigated in the last decades. Yet, experimental studies on neurocognitive markers of ASD have not been attentively compared with similar studies in patients with cerebellar primary disturbances (e.g., malformations, agenesis, degeneration, etc). Addressing this neglected issue could be useful to underline unexpected areas of overlap and/or underestimated differences between these sets of conditions. In fact, ASD and cerebellar primary disturbances (notably, Cerebellar Cognitive Affective Syndrome, CCAS) can share atypical manifestations in perceptual, sensory, and motor functions, but neural subcircuits involved in these anomalies/difficulties could be distinct. Here, we specifically deal with this issue focusing on four paradigmatic neurocognitive functions: visual and biological motion perception, multisensory integration, and high stages of the motor hierarchy. From a research perspective, this represents an essential challenge to more deeply understand neurocognitive markers of ASD and of cerebellar primary disturbances/CCAS. Although we cannot assume definitive conclusions, and beyond phenotypical similarities between ASD and CCAS, clinical and experimental evidence described in this work argues that ASD and CCAS are distinct phenomena. ASD and CCAS seem to be characterized by different pathophysiological mechanisms and mediated by distinct neural nodes. In parallel, from a clinical perspective, this characterization may furnish insights to tackle the distinction between autistic functioning/autistic phenotype (in ASD) and dysmetria of thought/autistic-like phenotype (in CCAS).

Restricted, Repetitive Behaviors in Autism Spectrum Disorder and Obsessive-Compulsive Disorder: A Comparative Review

This review paper critically examines literature regarding restricted and repetitive behaviors (RRBs) in Autism Spectrum Disorder (ASD) and Obsessive-Compulsive Disorder (OCD). The similar behavioral profiles of these disorders presents the potential for confusion regarding diagnoses and intervention efforts. As such, this review highlights the similarities and differences between RRBs in ASD and OCD. The developmental trajectories of RRBs are presented, followed by an exploration of three constructs implicated in RRB manifestation: anxiety, executive functioning, and sensory phenomena. While RRBs tend to develop with some similarity in both disorders, the differing role of anxiety highlights important distinctions between ASD and OCD. We urge researchers and clinicians to think critically about the dimensions that affect RRB presentation. Future research should use this review as a starting point to further elucidate the differences between RRBs in these two populations.

Comparison of a direct and an indirect approach for the functional assessment of insistence on sameness in a child with autism spectrum disorder and a typically developing child

OBJECTIVE

To compare indirect and direct functional assessment of insistence on sameness associated with autism spectrum disorder (ASD) and typical development.

METHODS

Parents rated the function of insistence on sameness for a 6-year-old boy with ASD (Peter) and a typically developing 4-year-old boy (Nathan) using the Motivation Assessment Scale (MAS). Ratings were compared to the results of a direct assessment.

RESULTS

The results of the assessment procedures were mainly consistent for Peter and suggested that his tendency to insist on sameness was maintained by sensory consequences. The finding of an attention function for Nathan in the play-based assessment was consistent with previous functional assessment studies surrounding typically developing children, but in contrast to the MAS.

CONCLUSION

While the play-based assessment may be more suitable for assessing the high rate insistence on sameness observed in individuals with ASD, the MAS may be more suitable for low rate insistence on sameness.
