Abstract

Objective: Inefficiencies in cognitive flexibility (CF) are a potential vulnerability trait for anorexia nervosa (AN). Yet, much of the research on CF in AN has been conducted in adult samples, with mixed results from research on adolescents. Knowledge of the prevalence of low scores on assessments can help avoid erroneous interpretations of test scores. The current study examined the prevalence of low scores on the Delis Kaplan Executive Function System (D-KEFS) in adolescents and adults with AN and adolescent healthy controls.

Method: We conducted a secondary analysis of D-KEFS data from 739 participants (552 adolescents with AN [aged 15.39 ± 1.91, 92% female], 69 adults with AN [aged 26.5 ± 6.1, 98.6% female], and 118 adolescent healthy controls [HC] [aged 15.09 ± 2.14, 98.3% female]).

Results: Low scores on the D-KEFS were common across all groups. Adults with AN exhibited the highest proportion of individuals with abnormally low scores, followed by adolescents with AN and adolescent HC. Adolescents with a higher proportion of low scores had a lower BMI z-score and longer length of illness.

Conclusions: Results highlight differences between adults and adolescents and lend support to the hypothesis that inefficiencies in flexibility are either a marker of persistent course or a scar of AN illness.

神经性厌食症患者Delis Kaplan执行功能系统评分低的基本比率。

目的：认知柔韧性低下（CF）是神经性厌食症（AN）的潜在易感特征。然而，大部分关于AN中CF的研究都是在成人样本中进行的，对青少年的研究结果好坏参半。了解低分的普遍性有助于避免对考试成绩的错误解读。本研究调查了患有AN的青少年和成人以及青少年健康对照组中Delis Kaplan执行功能系统（D-KEFS）低分的流行程度。方法：我们对739名参与者的D-KEFS数据进行二次分析，其中552名AN青少年[年龄15.39±1.91,92%为女性]，69名AN成人[年龄26.5±6.1,98.6%为女性]，118名青少年健康对照[HC][年龄15.09±2.14,98.3%为女性]。结果：D-KEFS的低得分在所有组中都很常见。成人AN患者异常低分比例最高，其次是青少年AN和青少年HC。低分比例越高的青少年BMI z-score越低，患病时间越长。结论：结果突出了成人和青少年之间的差异，并支持了灵活性低下要么是持续病程的标志，要么是AN疾病的疤痕的假设。
