To develop the Scale of Paranoid Personality Organization Type (SPPOT) and test its reliability and validity, the initial scale was developed based on the diagnostic standard in the Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5) of PPD, personality organization theory and the clinical behavior samples. Sample 1 of 683 effective participants filled out SPPOT and Millon Clinical Multiaxial Inventory-III (MCMI-III). Sample 2 of 484 subjects filled out SPPOT and Inventory of Personality Organization (IPO). 60 effective participants were involved in checking of test-retest correlation at 5-week intervals. The final version of SPPOT had 18 items (including 4 lie detection items) and 3 dimensions: Hostile (Ht), Distrust (Dt) and Paranoid Thinking (PT), which cumulatively explained 42.28% variance. The scale had good structural validity (χ²/df=1.1, RMSEA=0.01, GFI=0.98, NFI=0.95, CFI=0.99). Cronbach’s α of SPPOT, Ht, Dt and PT was 0.77, 0.64, 0.35 and 0.64 respectively. The intraclass correlation coefficient (ICC) of Ht, Dt, PT and SPPOT were 0.79, 0.72, 0.63 and 0.75 (P<0.001). The criterion-related validity with MCMI-III and IPO sounded acceptable (r=0.13–0.31, P<0.001). SPPOT generally meets the measurement requirements for paranoid personality types and levels of personality organization.

为编制偏执型人格组织类型量表(SPPOT)并探究其信效度, 以精神疾病诊断与统计手册第5版(DSM-5)诊断标准为框架, 结合人格组织理论和行为样本编制初始量表。样本1为683名有效被试填写的SPPOT和米隆临床多轴问卷(MCMI-III), 样本2为484名有效被试填写的SPPOT和人格组织问卷(IPO), 60名有效被试间隔5周填写SPPOT重测问卷。SPPOT包括18个条目(含4个测谎题), 分为敌意、不信任和偏执观念3个维度, 解释总变异的42.28%, 具有良好的结构效度(χ²/df＝1.1, RMSEA＝0.01, GFI＝0.98, NFI＝0.95, CFI＝0.99)。总量表及3个因子的Cronbach’s α系数分别为0.77, 0.64, 0.35和0.64, 重测组内相关系数分别为0.79, 0.72, 0.63和0.75 (P值均小于0.001)。SPPOT与MCMI-III和IPO的效标关联效度良好(r=0.13~0.31, P值均小于0.001)。偏执型人格组织量表(SPPOT)基本上达到测量学要求, 可用于偏执型人格类型和人格组织水平的测量。
