Set-shifting among adolescents with anorexia nervosa

Area of Science:

• Neuropsychology
• Developmental Psychology
• Eating Disorders Research

Background:

• Set-shifting difficulties are observed in adults with anorexia nervosa (AN).
• It remains unclear whether these difficulties are an early feature of AN or a consequence of chronic illness.
• Adolescence is the typical onset period for AN, necessitating investigation into early-stage cognitive function.

Purpose of the Study:

• To investigate set-shifting abilities in adolescents with short-duration AN.
• To compare executive functioning, specifically set-shifting, between adolescents with AN and healthy controls (HC).

Main Methods:

• Utilized the Delis-Kaplan executive functioning system and the Wisconsin Card Sorting Test (WCST) to assess set-shifting.
• Collected data on eating psychopathology.
• Compared a sample of 32 adolescent inpatients with AN to 22 healthy controls.

Main Results:

• No significant differences in set-shifting performance were found between adolescents with AN and healthy controls across most measures.
• This suggests that set-shifting deficits may not be present at the early stages of AN in adolescents.

Conclusions:

• The study's findings indicate that set-shifting difficulties in AN might be acquired rather than inherent.
• Further research with larger adolescent samples is recommended to identify potential subsets with set-shifting deficits and their relation to AN chronicity.
