• Self- and Other-Reports in Evaluating Emotion Regulation in Autism Spectrum Disorder and the Potential of Physiological Indices (2026) · Journal of Special Education Research · doi

  This review summarized findings from self- and other-report measures of emotion regulation (ER) in Autism Spectrum Disorder (ASD) and examined the potential contributions of physiological indices for evaluating emotional processes. This section highlights key considerations for future research, emphasizes the need to expand physiological investigations, and discusses the potential clinical and educational applications of these measures. First, this review identified discrepancies in findings on suppression strategies in ASD depending on whether self- or other-report methods were used. Each evaluation approach has distinct strengths and limitations that vary according to study design. Researchers must carefully consider which method is most appropriate for a given research question while remaining aware of the inherent constraints of each approach. Ideally, ER in ASD should be assessed using a multimethod strategy that integrates multiple sources of data, including self- and other-reports, behavioral observations, and physiological measures (Mazefsky et al., 2014; Okano et al., 2021). Second, there is a critical need for additional evidence from basic research employing physiological indices. Studies investigating suppression strategies using physiological measures remain scarce, and inconsistencies have been reported not only in self- and other- reports but also across neuroimaging studies. As noted by Sikka et al. (2022), these inconsistencies may arise in part from variations in experimental design or neuroimaging data processing. Nevertheless, certain brain regions, particularly the prefrontal cortex (PFC), have been consistently implicated in ER. Findings from basic research targeting these neural mechanisms may serve as valuable biomarkers for developing clinical assessment tools. Finally, the potential clinical applications of physiological indices merit consideration. As demonstrated by Reisinger et al. (2024), physiological measures can serve as outcome indicators in interventions designed to enhance ER. However, practical constraints often limit the use of large-scale neuroimaging equipment, such as functional magnetic resonance imaging (fMRI), in educational and developmental contexts, including schools, where financial, spatial, and personnel resources are limited. In such settings, more accessible indices, such as heart rate variability (HRV) and skin conductance, may provide practical and cost-effective means of assessment. For example, O’Haire et al. (2015) measured social stress in school environments using skin conductance and reported that children with ASD showed a 43% reduction in responses during free play with peers in the presence of animals compared with toys. Additionally, less intrusive neuroimaging techniques, such as near-infrared spectroscopy (NIRS), can enable multimodal evaluations by combining prefrontal activity with behavioral observations in naturalistic settings. Physiological indices may also facilitate objective evaluation of intervention outcomes and visualization of developmental progress. Because ER is not easily observable in everyday settings and may be partially inaccessible even via report- based assessments, these measures can provide meaningful developmental milestones. Such visualization may empower parents to better understand their child’s progress, inform caregiving strategies, and reinforce parental confidence in supporting their child’s emotional development. While these applications are preliminary, they hold significant promise as reliable, informative clinical tools for both research and practice.

• Conceptualizing Autism as a Behavioral Network: Transdiagnostic Associations with Co-occurring Psychiatric Conditions (2026) · Research on Child and Adolescent Psychopathology · cited 2× · doi

  First, causal conclusions are limited by the cross-sectional nature of the study and results can only demonstrate how a network of autism-related approach-withdrawal behav- iors relates to concurrent psychiatric symptomatology for autistic children between the ages of 6 and 11 years.
