鉴于行为抑制（BI）对社交焦虑和抑郁的影响，已经开发了几种具有成本效益的方法来检测这种特质。然而，没有一种工具可以使用心理健康专业人员的报告来获得BI的系统测量。本研究旨在探讨行为抑制观察系统（BIOS），一个简短的工具，使临床医生能够提供一个快速测量BI的心理测量特性。361名学龄前儿童的家长和教师提供了BI和精神病理学的措施。临床医生在与每个孩子单独会面后完成了BIOS。74名随机选择的儿童接受标准化观察。两名研究者在标准化观察后完成BIOS。结果表明，BIOS是在一个维度上结构化的，该维度解释了总方差的60%。它表现出良好的内部一致性（Cronbach's Alpha = .88）和良好的重测信度。BIOS评分与BI的观察指标适度收敛，并充分区分与BI无关的结构（如攻击性、破坏性行为或同伴冲突）。结果支持BIOS（需要3分钟完成的8项量表）对于捕获临床医生的BI测量值是有效和可靠的。BIOS可能有助于检测社交焦虑的气质倾向。
Given the implications of behavioral inhibition (BI) on social anxiety and depression, several cost-effective methods have been developed to detect this trait. However, there is no instrument for obtaining a systematic measurement of BI that uses the reports of mental health professionals. The present study aims to explore the psychometric properties of the Behavioral Inhibition Observation System (BIOS), a brief tool enabling clinicians to provide a quick measure of BI. Parents and teachers of 361 preschool children provided measures of BI and psychopathology. Clinicians completed the BIOS after an individual meeting with every child. Seventy-four randomly selected children were exposed to standardized observation. Two researchers completed the BIOS after standardized observation. The results show that the BIOS is structured in one dimension that explains 60 % of the total variance. It shows good internal consistency (Cronbach's Alpha = .88) and good test-retest reliability. The BIOS scores moderately converge with observational measures of BI and adequately distinguish constructs not related to BI (such as aggressiveness, disruptive behavior, or peer conflict). The results support that the BIOS, an 8-item scale that takes 3 min to complete, is valid and reliable for capturing a clinician's measure of BI. The BIOS may help to detect temperamental disposition to social anxiety.
