Youth with somatic symptom disorder (SSD) present unique behavioral characteristics.
To develop and examine the psychometric properties of an observational measure of behavioral characteristics for youth with SSD (the Somatization Behavioral Characteristics Questionnaire, SBCQ).
N = 80 youth with SSD and 31 with non-SSD impairments participated in this study (age = 13.91 ± 2.72, 14 ± 3.21, respectively; females: n = 61, 14, respectively). Symptom intensity (Children's Somatization Inventory-24; CSI-24), functional disability (Six-Minute Walk Test, walking rate of perceived exertion), and the SBCQ were assessed. SBCQ reliability and validity were examined.
SBCQ had acceptable reliability in both groups (Cronbach's α > 0.7). Exploratory factor analysis in the SSD group revealed a three-cluster solution. Significant associations were found between the SBCQ, CSI-24, and functional disability. Both groups differed in the prevalence of all SBCQ behaviors. The greatest differences were in the mismatch between etiology and clinical presentation, and in the exhibited lack of trust in the therapist and "la belle indifference". Receiver operating characteristic analysis showed that the SBCQ has moderate accuracy in discriminating between the two groups (area under the curve = 0.80). Sensitivity and specificity were 82.5% and 73.3%, respectively.
The SBCQ is psychometrically sound. Findings may aid in developing sensitive assessment tools for SSD and continuing education for therapists.
患有躯体症状障碍（SSD）的青少年表现出独特的行为特征。
开发并检验一种针对患有SSD的青少年行为特征的观察性测量工具（躯体化行为特征问卷，SBCQ）的心理测量特性。
80名患有SSD的青少年和31名患有非SSD损伤的青少年参与了本研究（年龄分别为13.91±2.72岁和14±3.21岁；女性分别为61名和14名）。评估了症状强度（儿童躯体化量表-24；CSI-24）、功能残疾（六分钟步行测试、主观用力行走速度）和SBCQ。检验了SBCQ的信度和效度。
SBCQ在两组中均具有可接受的信度（Cronbach'sα>0.7）。SSD组的探索性因素分析得出了一个三聚类解决方案。发现SBCQ、CSI-24和功能残疾之间存在显著关联。两组在所有SBCQ行为的患病率上存在差异。最大的差异在于病因与临床表现之间的不匹配，以及表现出对治疗师缺乏信任和“泰然漠视”。受试者工作特征分析表明，SBCQ在区分两组方面具有中等准确性（曲线下面积=0.80）。敏感性和特异性分别为82.5%和73.3%。
SBCQ在心理测量上是可靠的。研究结果可能有助于开发针对SSD的敏感评估工具以及为治疗师提供继续教育。
