Abstract：
Bodily Distress Syndrome (BDS) represents a new research concept for adult patients with various functional somatic syndromes. We evaluated the utility of the BDS research concept and the associated BDS-25-checklist as a screening tool for diverse functional somatic symptoms (FSS) in adolescence by investigating: 1) the psychometric and factorial structures of the checklist, 2) symptom cluster patterns and 3) illness classification and associations with emotional psychopathology and sociodemographic factors.
This cross-sectional study obtained data from the 16/17-year follow-up (N = 2542) of the general population Copenhagen Child Cohort 2000 (CCC2000). We used self-reported questionnaires to assess physical symptoms (the BDS-25 checklist), overall health (KidScreen), emotional psychopathology (Spence Children\'s Anxiety Scale; The Mood and Feelings Questionnaire), and illness worry (Whiteley-6 Index), and utilized data from Danish national registers to assess sociodemographic factors.
The BDS-25 checklist items displayed satisfactory psychometric data quality. Factor analyses revealed a similar four-factor model as reported in adults (factor loadings λ ≥0.5), representing distinct BDS symptom clusters: cardio-pulmonary, gastro-intestinal, musculoskeletal and general symptoms. Latent class analyses revealed a model with three latent classes, i.e. probable no to mild BDS, probable moderate, single-organ BDS and probable severe, multi-organ BDS, displaying acceptable class quality (Entropy = 0.904). Trend analyses revealed sociodemographic group differences across latent classes. Increased emotional psychopathology was associated with more pronounced BDS symptoms.
Our findings support the BDS concept with four symptom clusters and three illness severity groups (no BDS, single- organ and multi-organ BDS) to screen for FSS in adolescence.

摘要：
身体窘迫综合征（BDS）代表了具有各种功能性躯体综合征的成年患者的新研究概念。我们通过调查以下方面评估了BDS研究概念和相关的BDS-25清单作为青春期各种功能性躯体症状（FSS）的筛查工具的实用性：1）清单的心理测量和因子结构，2）症状群模式和3）疾病分类以及与情绪心理病理学和社会人口统计学因素的关联。
这项横断面研究从一般人群哥本哈根儿童队列2000（CCC2000）的16/17年随访（N=2542）中获得了数据。我们使用自我报告的问卷来评估身体症状（BDS-25清单），整体健康（KidScreen），情绪心理病理学(斯宾塞儿童焦虑量表；情绪和情感问卷)，和疾病担忧(怀特利6指数)，并利用丹麦国家登记册的数据来评估社会人口因素。
BDS-25检查表项目显示了令人满意的心理测量数据质量。因素分析显示，与成年人报告的四因素模型相似(因素负荷λ≥0.5)，代表不同的BDS症状群：心肺，胃肠道,肌肉骨骼和一般症状。潜在类分析揭示了一个具有三个潜在类的模型，即可能没有轻度BDS，可能中等,单器官BDS和可能严重，多器官BDS,显示可接受的类质量(熵=0.904)。趋势分析揭示了潜在类别之间的社会人口统计学群体差异。情绪心理病理学的增加与更明显的BDS症状有关。
我们的研究结果支持BDS概念，包括四个症状群和三个疾病严重程度组（无BDS，单器官和多器官BDS）在青春期筛查FSS。
