Measuring cognitive and affective empathy across positive and negative emotions: psychometric properties and measurement invariance of the Perth Empathy Scale

Empathy, a complex and multidimensional construct essential for social functioning and mental health, has been extensively studied in both research and clinical settings. The Perth Empathy Scale (PES), a recently developed self-report measure, assesses cognitive and affective empathy across both positive and negative emotions and is based on the self-other model of empathy. This study aimed to evaluate the psychometric properties of the Persian version of the PES in large Iranian sample.

Caregiver perspectives regarding the impact of feeding difficulties on mealtime participation for primary school-aged autistic children and their families

Although up to 89% of autistic children experience feeding difficulties, little is known about the impact of these difficulties on mealtime participation. The aim of this study was to explore the impact of feeding difficulties on the mealtime participation of autistic children and their families based on caregiver experiences.

Dental care experiences and clinical phenotypes in children on the autism spectrum

Children diagnosed with autism spectrum disorder may be at higher likelihood of experiencing poorer oral health and difficulties accessing dental health care. However, identifying which children on the autism spectrum may be more vulnerable to experiencing dental care difficulties is still unknown.

The Comprehensive Autistic Trait Inventory (CATI): development and validation of a new measure of autistic traits in the general population

Traits and characteristics qualitatively similar to those seen in diagnosed autism spectrum disorder can be found to varying degrees in the general population. To measure these traits and facilitate their use in autism research, several questionnaires have been developed that provide broad measures of autistic traits [e.g. Autism-Spectrum Quotient (AQ), Broad Autism Phenotype Questionnaire (BAPQ)]. However, since their development, our understanding of autism has grown considerably, and it is arguable that existing measures do not provide an ideal representation of the trait dimensions currently associated with autism. Our aim was to create a new measure of autistic traits that reflects our current understanding of autism, the Comprehensive Autism Trait Inventory (CATI).
