ABSTRACT

Objectives

Measurements are often developed for the assessment of personality disorders (PDs) in younger adults and seldom evaluated on the applicability in older adults. Remarkably, research has not yet been conducted into age-group appropriateness of the gold standard for the assessment of PDs, known as Structured Clinical Interview for DSM-IV Personality Disorders (SCID-II). Therefore, the current study empirically investigated the age-neutrality of the PDs assessed by the SCID-II.

Methods

Age-neutrality was examined in 84 younger adults (aged 20–45 years) and 68 older adults (aged 65–85) by Differential Item Functioning (DIF). The impact of DIF on scale level was further examined using Differential Test Functioning analyzes to examine the impact of the amount of DIF variance in the items on scale level.

Results

Overall, the great majority, 95.8% of the categorically measured items and 87.5% of the dimensionally measured items, was endorsed in the same way by younger adults and older adults with equal scores on the PD scale. Subsequent analyzes revealed no large DTF for PD scales.

Conclusions

Overall the SCID-II in an outpatient population is age-neutral for both categorically and dimensionally scored PD scales.

Clinical Implications

The SCID-II can be used for the assessment of PDs in older adults.

SCID-II 的年龄中立性：年轻门诊患者（20-45 岁）和老年门诊患者（65 岁以上）中功能不同的项目

摘要

目标

测量方法通常是为了评估年轻人的人格障碍（PD）而开发的，很少评估其在老年人中的适用性。值得注意的是，尚未对 PD 评估黄金标准（即 DSM-IV 型人格障碍结构化临床访谈 (SCID-II)）的年龄组适当性进行研究。因此，本研究实证研究了 SCID-II 评估的 PD 的年龄中性。

方法

通过差异项目功能 (DIF) 对 84 名年轻人（20-45 岁）和 68 名老年人（65-85 岁）进行了年龄中性检查。使用差异测试功能分析进一步检查 DIF 对量表水平的影响，以检查项目中 DIF 方差量对量表水平的影响。

结果

总体而言，绝大多数（95.8% 的分类测量项目和 87.5% 的维度测量项目）在 PD 量表上得到了相同分数的年轻人和老年人的认可。随后的分析显示 PD 量表没有大的 DTF。

结论

总体而言，门诊患者群体中的 SCID-II 在分类和维度评分 PD 量表中均与年龄无关。

临床意义

SCID-II 可用于评估老年人的 PD。
