目的：SCL-90和SCL-90- r是诊断心理困扰最常用的量表。为了减少和防止个体的超载，在SCL-90的基础上开发了18项简短症状量表（BSI-18）。由于心理障碍更常发生在老年人，因此越来越需要有效的工具来测量老年人的痛苦。然而，BSI-18的心理测量特性、规范值和析因结构尚未在该年龄组中进行调查。方法：本研究的目的是评估老年人样本的BSI-18，并为这一特定人群建立规范值。随后收集884例样本的人口学信息和BSI-18结果，其中女性占55%，平均年龄70.75岁，SD = 7.08，年龄范围60-95岁。问卷包含躯体化（SOMA）、焦虑（ANX）和抑郁（DEPR）三个6项量表，构成一般症状指数（GSI）。结果：我们发现了一个可接受的良好的模型拟合的三因素模型与一般的GSI因素。BSI-18的心理测量性质令人满意。严格的测量不变性显示年龄和性别。此外，我们发现基于社会人口变量的心理困扰差异。结论：这些发现强调了老年人越来越需要预防机制，例如（重新）激活他们的社会网络和加强他们的身心健康。
Objective: The SCL-90 and the SCL-90-R are the most applied measures regarding psychological distress. To reduce and prevent an overload to of the individuals, the Brief Symptom Inventory with 18 items (BSI-18) was developed based on the SCL-90. Since psychological disorders more frequently occur at an older age, there is a growing need for efficient instruments to measure distress in the elderly. However, the BSI-18's psychometric properties, norm values, and factorial structure have not yet been investigated in this age group.Methods: The aim of this study was to evaluate the BSI-18 in a sample of elderly people and to establish norm values for this specific population. Subsequently, demographic information and BSI-18 results were collected from a sample totaling 884 (55% female, mean age of 70.75years, SD = 7.08, age range = 60-95years). The questionnaire contains three six-item scales: somatization (SOMA), anxiety (ANX), and depression (DEPR), which form a general symptom index (GSI).Results: We found an acceptable to good model fit for a three-factor-model with a general GSI factor. The BSI-18's psychometric properties were satisfactory. Strict measurement invariance was shown for age and gender. Additionally, we found differences in psychological distress based on sociodemographic variables.Conclusions: These findings underline the growing need for preventive mechanisms for elderly people such as, e.g., (re)activating their social networks and strengthening their physical and psychological well-being.
