Abstract

Objective

Anxiety and depression symptoms are common in individuals with eating disorders. To study these co-occurrences, we need high-quality self-report questionnaires. The 19-item self-rated Comprehensive Psychopathological Rating Scale for Affective Syndromes (CPRS-S-A) is not validated in patients with eating disorders. We tested its factor structure, invariance, and differences in its latent dimensions.

Method

Patients were registered by 45 treatment units in the Swedish nationwide Stepwise quality assurance database for specialised eating disorder care (n = 9509). Patients self-reported their anxiety and depression symptoms on the CPRS-S-A. Analyses included exploratory and confirmatory factor analyses (CFA) in split samples, and testing of invariance and differences in subscales across eating disorder types.

Results

Results suggested a four-factor solution: Depression, Somatic and fear symptoms, Disinterest, and Worry. Multigroup CFA indicated an invariant factor structure. We detected the following differences: Patients with anorexia nervosa binge-eating/purging subtype scored the highest and patients with unspecified feeding and eating disorders the lowest on all subscales. Patients with anorexia nervosa or purging disorder show more somatic and fear symptoms than individuals with either bulimia nervosa or binge-eating disorder.

Conclusion

Our four-factor solution of the CPRS-S-A is suitable for patients with eating disorders and may help to identify differences in anxiety and depression dimensions amongst patients with eating disorders.

饮食失调患者的潜在焦虑和抑郁维度不同:瑞典全国调查

焦虑和抑郁症状在饮食失调患者中很常见。为了研究这些共现现象，我们需要高质量的自我报告问卷。19项自评情感综合征综合精神病理评定量表(CPRS-S-A)未在饮食失调患者中得到验证。我们测试了它的因素结构、不变性和潜在维度的差异。方法在瑞典全国逐步质量保证数据库中对45个治疗单位的患者进行登记，用于专门的饮食失调治疗(n = 9509)。患者在CPRS-S-A中自我报告焦虑和抑郁症状。分析包括在分裂样本中进行探索性和验证性因素分析(CFA)，并测试饮食失调类型的亚量表的不变性和差异。结果提出了四因素解决方案:抑郁、躯体和恐惧症状、冷漠和担忧。多组CFA显示因子结构不变。我们发现了以下差异:神经性厌食症暴食/泻食亚型患者在所有亚量表上得分最高，未指明的进食障碍患者得分最低。神经性厌食症或排便障碍患者比神经性贪食症或暴食症患者表现出更多的躯体和恐惧症状。结论本研究的四因素CPRS-S-A量表适用于进食障碍患者，有助于识别进食障碍患者焦虑和抑郁维度的差异。

期刊介绍： The International Journal of Methods in Psychiatric Research (MPR) publishes high-standard original research of a technical, methodological, experimental and clinical nature, contributing to the theory, methodology, practice and evaluation of mental and behavioural disorders. The journal targets in particular detailed methodological and design papers from major national and international multicentre studies. There is a close working relationship with the US National Institute of Mental Health, the World Health Organisation (WHO) Diagnostic Instruments Committees, as well as several other European and international organisations. MPR aims to publish rapidly articles of highest methodological quality in such areas as epidemiology, biostatistics, generics, psychopharmacology, psychology and the neurosciences. Articles informing about innovative and critical methodological, statistical and clinical issues, including nosology, can be submitted as regular papers and brief reports. Reviews are only occasionally accepted. MPR seeks to monitor, discuss, influence and improve the standards of mental health and behavioral neuroscience research by providing a platform for rapid publication of outstanding contributions. As a quarterly journal MPR is a major source of information and ideas and is an important medium for students, clinicians and researchers in psychiatry, clinical psychology, epidemiology and the allied disciplines in the mental health field.
