As previous studies have shown that personality disorder (PD) assessment in older adults is often hampered because assessment tools are tailored toward younger adults, establishing the age-neutrality of novel tools is crucial. This study primarily aimed to evaluate the age-neutrality of the Level of Personality Functioning Brief Form (LPFS-BF 2.0) and the Personality Inventory for -5 Modified + (PID-5-BF+M), using a sample of 254 community-dwelling adults. The analysis of Differential Item Functioning (DIF) demonstrated the age-neutrality of both instruments, with only 8.3% of LPFS-BF 2.0 items and 5.6% of PID-5-BF+M items exhibiting DIF. Differential Test Functioning (DTF) analyses revealed large DTF for the LPFS-BF 2.0 total score, indicating that age-specific norms might be necessary for this score. In summary, this study supports the use of these instruments in both older and younger adults, enhancing the assessment of PDs across the life span.
如先前研究所示，由于评估工具是为年轻人量身定制的，因此对老年人进行人格障碍 (PD) 评估常常受到阻碍，因此确定新工具的无年龄偏见至关重要。本研究主要旨在使用 254 名社区居住成年人的样本，评估人格功能简式评定量表 (LPFS-BF 2.0) 和人格障碍检查表修订版 + 短式 (PID-5-BF+M) 的无年龄偏见性。差异项目功能分析 (DIF) 表明，这两种工具均具有无年龄偏见性，仅 8.3%的 LPFS-BF 2.0 项目和 5.6%的 PID-5-BF+M 项目表现出 DIF。差异测试功能 (DTF) 分析表明，LPFS-BF 2.0 总分的 DTF 较大，表明对于该分数可能需要特定年龄的常模。总之，这项研究支持在老年人和年轻人中使用这些工具，以增强整个生命周期的 PD 评估。
