PMID 40452234

WHAT IT FOUND

Autistic traits predicted schizoid and obsessive-compulsive personality dimensions, while alexithymia predicted schizoid and borderline dimensions.

Avoidant traits were linked to depression and anxiety, not autism or alexithymia. These overlaps suggest diagnostic assessments should distinguish between core conditions and co-occurring emotional processing difficulties.

Key findings

01Both autistic and alexithymic traits significantly predicted the schizoid personality disorder dimension.

02Autistic traits were significant predictors of the obsessive-compulsive personality disorder (OCPD) dimension.

03Alexithymic traits, but not autistic traits, significantly predicted the borderline personality disorder dimension.

What it does not show

The study design is cross-sectional and correlational, so it cannot prove that autistic or alexithymic traits cause personality disorder dimensions. Participants were recruited from a specialist clinic and a research group, which may not represent the general population of people with autism or social difficulties. The use of self-report measures for autism and alexithymia can be problematic in clinical populations due to differences in how symptoms are perceived and reported. Sex was not included as a moderator in the main analysis due to sample size constraints, despite known biases in these measurement tools.

Declared interests

The authors declared no potential conflicts of interest.

The easy way to misread this

Do not assume that social avoidance in autistic individuals is primarily driven by autistic traits. In this study, avoidant personality dimensions were predicted by depression and social anxiety, not by autism or alexithymia scores.
