OBJECTIVE
Research has suggested that a fundamental aspect of anorexia nervosa (AN) is its egosyntonic nature, the fact that it is often valued by individuals with the disorder. The current study describes the development of the P-CAN, a quantitative measure of both positive (valued) and negative aspects of AN.
METHOD
Items were derived from a previous qualitative study (Serpell, Treasure, Teasdale, & Sullivan. 1999. International Journal of Eating Disorders, 25, 177-186). Data from 233 women with AN were subjected to a principal components analysis.
RESULTS
Ten subscales were identified, six describing the pros of AN and four describing the cons of the illness.
DISCUSSION
The P-CAN shows good psychometric properties and should prove a useful tool for the measurement of attitudes towards AN, as well as offer insights into the maintenance of the disorder.
目的
研究表明神经性厌食症（AN）的一个基本特征是其与自我一致的性质，即患有该疾病的个体常常重视这一特征。本研究描述了P-CAN的开发过程，P-CAN是一种对神经性厌食症的积极（受重视）和消极方面进行量化的测量工具。
方法
条目来源于之前的一项定性研究（塞尔佩尔、特雷热、蒂斯代尔和沙利文，1999年。《国际进食障碍杂志》，第25卷，第177 - 186页）。对233名患有神经性厌食症的女性的数据进行主成分分析。
结果
确定了十个分量表，六个描述神经性厌食症的益处，四个描述该疾病的弊端。
讨论
P-CAN显示出良好的心理测量特性，应该会被证明是一种用于测量对神经性厌食症态度的有用工具，同时也能为该疾病的维持机制提供见解。
