The Frontal Systems Behavior Scale (FrSBe) is a 46-item questionnaire that measures behaviors associated with frontal subcortical deficits (apathy, disinhibition, and executive dysfunction) in adult neurologic populations. Based on findings from a previous exploratory factor analysis on the scale, the current study used confirmatory factor analysis to explore and potentially improve on the measurement model fit of current FrSBe scores. Model fit indices and reliabilities (measured using internal consistency reliability) were compared in the original and in several alternative models. The original scale demonstrated a generally good fitting model, although the best fitting model (referred to as the reduced model) removed eight items from the original measure and modestly improved model fit over the original FrSBe. Strong reliability was found in both versions. Results from the current study provide a critical first step in a potential FrSBe scale revision.
额叶系统行为量表（FrSBe）是一个包含 46 个项目的问卷，用于测量成人神经人群中与额叶皮质下缺陷相关的行为（冷漠、抑制障碍和执行功能障碍）。基于对该量表的先前探索性因素分析的结果，本研究使用验证性因素分析来探索和潜在地改善当前 FrSBe 评分的测量模型拟合度。在原始模型和几个替代模型中比较了模型拟合指数和可靠性（使用内部一致性可靠性来衡量）。原始量表表现出一般良好的拟合模型，尽管最佳拟合模型（称为简化模型）从原始测量中删除了 8 个项目，并适度提高了原始 FrSBe 的模型拟合度。两个版本都具有很强的可靠性。本研究的结果为 FrSBe 量表修订提供了一个关键的第一步。
