Abstract

Objective

Motivation to change is an important predictor for treatment outcomes in individuals with anorexia nervosa (AN), however, the existence and clinical relevance of distinct motivational dimensions are understudied. This study aimed to structurally validate the AN Stage of Change Questionnaire (ANSOCQ) in the Italian adult AN population to identify separate motivational dimensions and their association with clinical variables and outcomes.

Method

Inpatients and outpatients with AN (N = 300) completed the ANSOCQ and measures assessing eating and depressive psychopathology. Unique Variable Analysis and Exploratory Graph Analysis were employed to identify dimensions in the network structure of ANSOCQ. Cross-sectional associations with clinical variables were assessed in the whole sample. Predictive value on weight and psychopathology was assessed in inpatients.

Results

Two dimensions were identified, one comprising items relative to weight gain, and the second items regarding attitudes towards eating, body, and emotional problems. Feelings associated with eating resulted as most central in the network. Higher scores in the first dimension and ANSOCQ total predicted weight gain during hospitalisation. No significant predictors emerged for changes in eating psychopathology.

Discussion

These findings confirm the robust psychometric properties of ANSOCQ and provide support for the use of its subdimensions in clinical practice.

动机的结构：通过对意大利语版 "神经性厌食症改变阶段问卷 "进行网络验证，评估改变准备度及其预测价值。

目的：改变动机是预测神经性厌食症（AN）患者治疗结果的重要指标，然而，不同动机维度的存在及其临床相关性却未得到充分研究。本研究旨在对意大利成人厌食症患者的厌食症改变阶段问卷（ANSOCQ）进行结构性验证，以确定不同的动机维度及其与临床变量和疗效的关系：方法：患有自闭症的住院和门诊患者（N = 300）完成 ANSOCQ 以及评估饮食和抑郁心理病理学的测量。采用独特变量分析法和探索性图表分析法确定ANSOCQ网络结构中的维度。在整个样本中评估了与临床变量的横截面关联。对住院病人体重和精神病理学的预测价值进行了评估：结果：确定了两个维度，一个是与体重增加有关的项目，另一个是与对饮食、身体和情绪问题的态度有关的项目。与进食有关的感觉在网络中占据最重要的位置。第一个维度和 ANSOCQ 总分越高，就越能预测住院期间体重增加的情况。饮食心理病理学的变化没有出现明显的预测因素：这些研究结果证实了 ANSOCQ 强大的心理测量特性，并为在临床实践中使用其子维度提供了支持。
