Attention to detail in Italian parents of women with anorexia nervosa: a comparative study.

Aim: Anorexia nervosa (AN) and autistic spectrum disorder (ASD) may share traits such as mental rigidity and attention to detail, some of which might be familial. We aimed to investigate the distribution of autistic traits among parents of daughters suffering from eating disorders (anorexia or bulimia nervosa), comparing them with control parents.

Methods: As a whole, 40 parents of women with eating disorders (60% AN, 40% BN) and 33 control parents were recruited and accepted an examination through the administration of the autism spectrum quotient (AQ). The effects of eating disorders and other psychiatric traits were excluded by using EAT-26 and SCL-90-R respectively, while decision making skills were ruled out by using the cognitive estimation task (CET).

Results: AQ scores revealed a between-groups difference for a specific trait, showing a reduction in attention to detail among ED family members, especially AN parents.

Discussion: These findings suggest a preference for global processing in AN parents in contrast to what found in AN patients. Our findings support the role of a candidate trait in AN parents, supporting the need of further studies on the role of attention to detail as a family marker.

Conclusion: This study identified a global processing preference in AN parents, suggesting a role of attention to detail as an ideal marker to be included in a wider clinical assessment for AN patients and their families. Considering some study limitations, further research is needed.
