While diagnostic pathways for identifying Autism in eating disorder (ED) populations have been developed, the field continues to lack validated psychometric tools to measure EDs for use in the Autistic population. Many commonly used measures for EDs potentially lack validity and reliability in the Autistic population limiting theoretical and practical advancements in the field. This paper outlines current conflicts in autism and ED research and how these can be addressed through psychometric methodology.

Background: Mentally-generated soothing imagery is a therapeutic technique to support mental wellbeing, but some individuals may require support using externally presented stimuli. Project Soothe was launched to collect soothing images using a citizen science approach. This online pilot study evaluated the first 575 soothing images collected, examining: 1) if the images were perceived to be soothing; 2) if viewing the images had a positive impact on mood; and 3) if mood effects were influenced by individual differences in age, gender and depressive symptoms.

Background: Sensory processing differences are commonly experienced by autistic individuals, and some sensory experiences can greatly impact the mental health and quality of life of individuals. Previous research suggests that adapting the sensory nature of environments may improve individual experiences and engagement with these spaces. However, knowledge about which public places are particularly disabling is limited, especially from the perspective of autistic individuals.

Article Synopsis
  • The study examined how autistic individuals respond to sensory stimuli, focusing on three main traits: hyperreactivity (HYPER), hyporeactivity (HYPO), and sensory seeking (SEEK).
  • Using data from 3,868 autistic youth, the researchers applied advanced statistical methods to explore the relationships between these traits across different sensory modalities.
  • Results showed that while a general pattern of HYPER responses could be validated, HYPO responses were less consistent, and SEEK had a more limited version, indicating that sensory responses in autism vary significantly and require nuanced assessment.
