Abstract

Background: Treating patients with anorexia nervosa (AN) is generally prolonged or often ineffective. A key factor influencing treatment is the high level of ambivalence patients feel regarding the necessary behavioral changes. We examined the trajectories of patients' readiness to change throughout their inpatient stay, considering the influence of their illness perceptions.

Methods: Data from clinical routine monitoring at the Department of Psychosomatic Medicine at Medical University Innsbruck, collected between 2015 and 2024, were analyzed. Monitoring included questionnaires assessing readiness to change (Fragebogen zur Erfassung der Veränderungsbereitschaft [FEVER], biweekly) and the patients' individual perception of illness (Brief Illness Perception Questionnaire [B-IPQ], weekly). Data analysis was conducted using linear mixed models, considering data from 189 adult patients (2321 data points) diagnosed with AN or atypical AN (F 50.0, F 50.1; 94.9% female; average length of hospital stay 5.3 weeks).

Results: Willingness to change shifted during treatment, with lower precontemplation and higher action scores at discharge. In linear mixed-effects models, higher perceived treatment control, illness concern, and consequences were significantly associated with more advanced stages of change.

Conclusion: The results indicate that an individual's perception of their illness influences their readiness to change. This underscores the importance of continuously integrating patients' perceptions into treatment and collaboratively addressing their assumptions and beliefs.

个体疾病知觉对神经性厌食症患者行为改变意愿的影响。

背景：神经性厌食症（AN）的治疗通常需要很长时间，或者常常无效。影响治疗的一个关键因素是患者对必要的行为改变的高度矛盾心理。考虑到他们的疾病感知的影响，我们检查了患者在住院期间准备改变的轨迹。方法：对2015 - 2024年因斯布鲁克医科大学心身医学系临床常规监测数据进行分析。监测包括评估改变准备程度的问卷（Fragebogen zur Erfassung der Veränderungsbereitschaft [FEVER]，两周一次）和患者个人对疾病的感知（简短疾病感知问卷[B-IPQ]，每周一次）。采用线性混合模型进行数据分析，考虑诊断为AN或非典型AN的189名成年患者（2321个数据点）的数据(F 50.0, F 50.1；94.9%的女性;平均住院时间5.3周)。结果：治疗过程中改变意愿发生变化，出院时预思考得分较低，行动得分较高。在线性混合效应模型中，更高的感知治疗控制、疾病关注和后果与更高级的变化阶段显著相关。结论：结果表明个体对疾病的认知影响其改变的准备程度。这强调了不断将患者的看法整合到治疗中并协作解决他们的假设和信念的重要性。
