The goal of this research is to evaluate the psychometric qualities of the Polish version of the SCL-27-plus questionnaire in terms of its five factor structure, internal consistency and theoretical accuracy.
A total of 1.350 persons of which 62% were males, participated in the study. 651 persons were tested with a paper version, 699 subjects received an electronic version of the questionnaire. 336 (tested with the paper version) were patients with diagnosed psychiatric disorders. Paper version participants also filled out the General Health Questionnaire (GHQ-28).
Confirmatory factor analysis validated the five factor structure of SCL-27-plus when some errors terms within subscales are allowed to correlate (Depending on the sample: 1.64 < or = chi2/df < or = 2.46; 0.05 < or = RMSEA < or = 0.06; 0.91 < or = CFI < or = 0.95). Cronbach's Alpha reliability measures for the Global Severity Index was 0.90 to 0.92 and for the particular subscales 0.71 to 0.88. The GSI and symptom subscales for SCL-27-plus correlated with their equivalences in the GHQ-28 moderately to highly (r = 0.38 to 0.68). Strong differences occurred between the "clinical" and "non-clinical" groups in the levels of general and specific symptoms (Cohen's d from 0.42 to 1.15).
The Polish version of the SCL-27-plus questionnaire demonstrates good psychometric qualities. It can be used to measure the general intensity of psychopathological impairment as well as the specific subscales.
本研究的目的是从五因素结构、内部一致性和理论准确性方面评估波兰语版SCL - 27 +问卷的心理测量学特性。
共有1350人参与了该研究，其中62%为男性。651人接受纸质版测试，699人收到问卷电子版。336名（接受纸质版测试）为已确诊精神疾病的患者。纸质版参与者还填写了一般健康问卷（GHQ - 28）。
验证性因素分析在允许分量表内一些误差项相关时验证了SCL - 27 +的五因素结构（取决于样本：1.64≤卡方/自由度≤2.46；0.05≤近似均方根误差≤0.06；0.91≤比较拟合指数≤0.95）。全球严重程度指数的克朗巴哈α信度测量值为0.90至0.92，特定分量表为0.71至0.88。SCL - 27 +的GSI和症状分量表与其在GHQ - 28中的等效项中度至高度相关（r = 0.38至0.68）。“临床”组和“非临床”组在一般和特定症状水平上存在显著差异（科恩d值从0.42至1.15）。
波兰语版SCL - 27 +问卷显示出良好的心理测量学特性。它可用于测量心理病理损害的总体强度以及特定分量表。
