The Derogatis symptom checklist (SCL-90-R) and its short version, the Brief Symptom Inventory (BSI), are widely used instruments, despite the fact that their factor structures were not clearly confirmed. The goals of this research were to compare four measurement models of these instruments including one-factor, nine-factor, a second-ordered factor model and a bifactor model, in addition to testing the gender difference in symptom factors in a community sample. SCL-90-R was assessed in a large community survey which included 2710 adults who represent the population of Hungary. Statistical analyses included a series of confirmatory factor analyses and multiple indicator multiple cause (MIMIC modeling). The responses to items were treated as ordinal scales. The analysis revealed that the bifactor model yielded the closest fit in both the full SCL-90-R and BSI; however the nine-factor model also had an acceptable level of fit. As for the gender differences, women scored higher on global severity, somatization, obsession-compulsion, interpersonal sensitivity, depression and anxiety factors. Men scored higher on hostility and psychoticism. The bifactor model of symptom checklist supports the concept of global symptom severity and specific symptom factors. Global symptom severity explains the large correlations between symptom factors.
德若伽提斯症状清单（SCL-90-R）及其简短版，即Brief Symptom Inventory（BSI），是广泛使用的工具，尽管其因子结构并未得到明确证实。本研究的目的是比较这些工具的四种测量模型，包括单因素、九因素、二阶因子模型和双因素模型，此外还在社区样本中测试了症状因子的性别差异。SCL-90-R 在一项大型社区调查中进行了评估，该调查包括 2710 名代表匈牙利人口的成年人。统计分析包括一系列验证性因子分析和多指标多原因（MIMIC）建模。对项目的反应被视为有序量表。分析表明，双因素模型在完整的 SCL-90-R 和 BSI 中都具有最接近的拟合度；然而，九因素模型也具有可接受的拟合度。至于性别差异，女性在总体严重程度、躯体化、强迫观念-强迫行为、人际关系敏感、抑郁和焦虑因子上的得分较高。男性在敌对和精神病性上的得分较高。症状清单的双因素模型支持总体症状严重程度和特定症状因子的概念。总体症状严重程度解释了症状因子之间的大相关性。
