Anorexia nervosa (AN) is a severe mental illness. Personality traits and comorbidity with affective and anxiety disorders are key-aspects of its pathogenesis but little attention has been paid so far to affective temperaments in AN. Also, childhood anxiety is proposed to impact on AN clinical severity. Therefore, we aimed to investigate if affective temperaments could be related to AN eating psychopathology also clarifying if those with low versus high scores on depressive and anxious temperaments could differ in AN clinical current and lifetime severity.
One-hundred and forty-seven inpatients with AN were consecutively recruited. All participants completed: Temperament Evaluation of Memphis, Pisa, Paris and San Diego-Autoquestionnaire, Eating Disorder Examination Questionnaire, State Trait Anxiety Inventory, Beck Depression Inventory. Clinical data were collected upon admission.
Regression models showed that all affective temperaments were associated with eating psychopathology (eating restraint and eating, shape, and weight concerns); however, when controlling for confounders, only the anxious temperament remained significant. Also, those patients with higher scores on depressive and anxious temperaments reported higher current and lowest lifetime body mass index (BMI).
Only inpatients were recruited; self-report assessments were used and follow-up data are lacking.
Results from this study support the association between affective (anxious in particular) temperament traits and the presence of altered eating psychopathology in AN. Also, higher traits of depressive and anxious temperaments reported higher current and lowest lifetime BMI. Should these findings be confirmed, the assessment of the anxious temperament could fruitfully inform prevention and treatment interventions for AN.
神经性厌食症（AN）是一种严重的精神疾病。人格特质以及与情感和焦虑症的共病是其发病机制的关键方面，但迄今为止，AN中的情感气质很少受到关注。此外，有人提出儿童期焦虑会影响AN的临床严重程度。因此，我们旨在研究情感气质是否可能与AN的饮食心理病理学相关，同时也阐明抑郁气质和焦虑气质得分低与高的患者在AN的当前和终生临床严重程度上是否存在差异。
连续招募了147名AN住院患者。所有参与者均完成了：孟菲斯、比萨、巴黎和圣地亚哥气质评估-自填问卷、饮食失调检查问卷、状态特质焦虑量表、贝克抑郁量表。入院时收集临床数据。
回归模型显示，所有情感气质均与饮食心理病理学（饮食限制以及对饮食、体型和体重的关注）相关；然而，在控制混杂因素后，只有焦虑气质仍然显著。此外，抑郁气质和焦虑气质得分较高的患者报告的当前体重指数（BMI）较高，终生BMI最低。
仅招募了住院患者；使用了自我报告评估且缺乏随访数据。
本研究结果支持情感（尤其是焦虑）气质特质与AN中饮食心理病理学改变之间的关联。此外，抑郁气质和焦虑气质得分较高的患者报告的当前BMI较高，终生BMI最低。如果这些发现得到证实，焦虑气质的评估可为AN的预防和治疗干预提供有益信息。
