The focus of these analyses was to examine the psychometric properties of the Lichtenberg Financial Decision Screening Scale (LFDSS). The purpose of the screen was to evaluate the decisional abilities and vulnerability to exploitation of older adults. Adults aged 60 and over were interviewed by social, legal, financial, or health services professionals who underwent in-person training on the administration and scoring of the scale. Professionals provided a rating of the decision-making abilities of the older adult. The analytic sample included 213 individuals with an average age of 76.9 (SD = 10.1). The majority (57%) were female. Data were analyzed using item response theory (IRT) methodology. The results supported the unidimensionality of the item set. Several IRT models were tested. Ten ordinal and binary items evidenced a slightly higher reliability estimate (0.85) than other versions and better coverage in terms of the range of reliable measurement across the continuum of financial incapacity.
这些分析的重点是检验利希滕贝格金融决策筛选量表（LFDSS）的心理测量特性。该筛选的目的是评估老年人的决策能力以及被剥削的易感性。60岁及以上的成年人由社会、法律、金融或医疗服务专业人员进行访谈，这些专业人员接受了关于该量表管理和评分的现场培训。专业人员对老年人的决策能力进行评分。分析样本包括213名个体，平均年龄为76.9岁（标准差=10.1）。大多数（57%）为女性。数据采用项目反应理论（IRT）方法进行分析。结果支持了项目集的单维性。测试了几种IRT模型。十个有序和二元项目的可靠性估计略高（0.85），高于其他版本，并且在整个金融无行为能力连续体的可靠测量范围内具有更好的覆盖范围。
