Eliciting Expressions of Emotion: An Exploratory Analysis of Alexithymia in Adults with Autism Utilising the APRQ.

This study looked at how adults with autism express emotions in writing compared to people without autism. Researchers gave both groups emotional scenarios and analysed their written responses. Adults with autism used fewer emotion words and had less detailed emotional descriptions. Interestingly, their responses related to autism symptoms but not to scores on a standard emotion questionnaire, suggesting current tools might miss important aspects of how autistic people experience and express emotions.

This exploratory study compared emotional expression abilities between 32 adults with autism and 32 neurotypical controls using the Alexithymia Provoked Responses Questionnaire (APRQ) as an alternative to the standard TAS-20 alexithymia measure. Researchers analysed participants' written responses to emotional scenarios using computational linguistics approaches (LIWC and tidytext). Adults with autism used significantly fewer emotion words and showed reduced emotional granularity in their responses. Importantly, emotional word use correlated with autism symptom severity but not with TAS-20 scores, suggesting the TAS-20 may miss important aspects of alexithymia in autism.

The APRQ combined with advanced text analysis shows promise for better understanding emotional expression difficulties in autism.

The APRQ with computational text analysis may offer a more sensitive assessment of emotional expression difficulties in autism than traditional measures. This could improve identification of alexithymia and inform therapeutic approaches targeting emotional awareness and expression skills.

Small sample size (n=32 per group) limits generalisability. Study design unclear from abstract. Cross-sectional design prevents causal inferences. Limited to written responses which may not reflect verbal emotional expression abilities.

This study examined alternative methods for detecting alexithymia to the Toronto Alexithymia Scale-20 (TAS-20) by comparing the emotional linguistic performance of ASD and NT samples (n = 32 in each) on the Alexithymia Provoked Responses Questionnaire (APRQ). We utilised both the LIWC and tidytext approaches to linguistic analysis. The results indicate the ASD sample used significantly fewer affective words in response to emotionally stimulating scenarios and had less emotional granularity. Affective word use was correlated with ASD symptomatology but not with TAS-20 scores, suggesting that some elements of alexithymia are not well detected by the TAS-20 alone.

The APRQ, in combination with the tidytext package, offers significant potential for sophisticated exploration of emotional expression in ASD.
