Are Autistic and Alexithymic Traits Distinct? A Factor-Analytic and Network Approach.

PMID 34060002WHAT IT FOUND
Autistic and alexithymic traits are distinct, not the same thing.
This means a patient's difficulty identifying emotions is not automatically a core symptom of their autism. Assess both separately to understand their specific needs.
Key findings
01Factor and network analyses showed that autistic and alexithymic traits cluster separately, supporting the view that they are distinct conditions.
02Confirmatory factor analysis found that models treating autism and alexithymia as separate constructs fit the data better than models treating them as a single common factor.
03The results suggest that assessing alexithymia specifically is needed when working with autistic individuals, as emotional difficulties may stem from alexithymia rather than autism itself.

What it does not show
The clinical sample was heterogeneous, grouping people with autism together with those with other conditions like depression and anxiety. Most diagnoses were self-reported and not independently verified. The study used a cross-sectional design, so it cannot determine causal relationships between the traits. The sample had a higher proportion of female and non-binary participants than is typical in autism research, which may limit generalizability.
Declared interests
Funding was provided by the Medical Sciences Division at the University of Oxford, the Baily Thomas Charitable Fund, and the Economic and Social Research Council. No specific conflicts of interest were declared in the text.
The easy way to misread this
Do not assume that because the traits are distinct, they never overlap or influence each other. The study found they are separate constructs, but they frequently co-occur and are positively correlated. A patient can have both, and treating one may not automatically resolve the other.
