The Personality Inventory for , Brief Form (PID-5-BF) was developed with an assumption of invariance across sexual and gender minority (SGM) individuals. This assumption has yet to be tested empirically. Using multigroup confirmatory factor analysis, we examined measurement invariance in the PID-5-BF across the SGM status in clinical ( = 1,174; = 254 SGM) and nonclinical ( = 1,456; = 151 SGM) samples. Measurement invariance was supported for the PID-5-BF structure, item thresholds, and factor loadings, but not at the item intercept level. SGM individuals endorsed higher negative affectivity, antagonism, disinhibition, and psychoticism domains in both samples. In the clinical sample, adjusting for partial invariance decreased detachment and antagonism levels for SGM persons. In the nonclinical sample, adjusting for partial invariance reduced antagonism disparities in the SGM group, even rendering original group differences null. Our results support the use of the PID-5-BF in SGM populations but indicate that some measurement bias may drive observed disparities in maladaptive trait domains and, in turn, personality disorder diagnosis.
人格障碍检查表简式量表（PID-5-BF）的制定假设了跨性少数群体（SGM）个体的不变性。这一假设尚未经过实证检验。本研究采用多群组验证性因素分析，在临床样本（n=1174，SGM=254）和非临床样本（n=1456，SGM=151）中，考察了 PID-5-BF 中 SGM 状态的测量不变性。PID-5-BF 的结构、项目门槛和因子负荷具有测量不变性，但项目截距水平没有不变性。在两个样本中，SGM 个体在负性情绪、敌对、冲动和精神病性等领域的得分更高。在临床样本中，对部分不变性进行调整后，SGM 个体的去人格化和敌对程度降低。在非临床样本中，对部分不变性进行调整后，SGM 组的敌对差异减小，甚至使原有的组间差异变得无统计学意义。本研究结果支持在 SGM 人群中使用 PID-5-BF，但表明一些测量偏差可能导致适应不良特质领域的观察到的差异，并进而影响人格障碍的诊断。
