BACKGROUND
The aim of this study was to adapt and obtain validity evidence of the Spanish Green Paranoid Thought Scales (S-GPTS).
METHOD
191 Spanish people responded to S-GPTS, Peters Delusions Inventory (PDI), and measures of psychopathology.
RESULTS
Principal Component Analyses on the polychoric correlation matrix identified two factors accounting for 71.0% of the cumulative variance. Cronbach alphas for S-GPTS total and its subscales were above .90 in clinical and non-clinical group. The value of the area under the receiver operating characteristic curve was higher for the S-GPTS (.898), than for the PDI (.859). The best S-GPTS threshold to discriminate between cases and non-cases was 92 (sensitivity, 97.35%; specificity, 65%). S-GPTS scores positively correlated with PDI and measures of anxiety and depression.
CONCLUSION
The S-GPTS has adequate psychometric properties to provide valid measures of delusional ideation in a Spanish population.
背景
本研究旨在改编并获取西班牙版绿色偏执思维量表（S-GPTS）的效度证据。
方法
191名西班牙人对S-GPTS、彼得斯妄想量表（PDI）以及精神病理学测量量表进行了作答。
结果
对多系列相关矩阵进行主成分分析，确定了两个因素，它们占累积方差的71.0%。在临床组和非临床组中，S-GPTS总量表及其分量表的克朗巴哈系数均高于0.90。S-GPTS的接受者操作特征曲线下面积值（0.898）高于PDI（0.859）。区分病例与非病例的最佳S-GPTS阈值为92（灵敏度为97.35%；特异度为65%）。S-GPTS得分与PDI以及焦虑和抑郁测量量表呈正相关。
结论
S-GPTS具有足够的心理测量学特性，能够为西班牙人群中的妄想观念提供有效的测量。
