ABSTRACT

Objective: Develop and validate the Behavioral Assessment Screening Tool for Adolescents with brain injury.

Setting: Concussion clinics

Participants: Adolescents with mild traumatic brain injury 3 months after initial concussion clinic visit (n = 138).

Design: Assessment development and validation (cross-sectional cohort) study

Main Measures: Behavioral Assessment Screening Tool – Adolescent

Results: Expert panel members added or modified items specific to adolescents to the original Behavioral Assessment Screening Tool for adults. The Content Validity Index was 97.2%. Exploratory factor analysis of the Behavioral Assessment Screening Tool – Adolescent reduced the initial 70 items to 46 primary items with a 3-factor solution: Negative Affect & Fatigue, Executive & Social Function, and Risk Behaviors. Internal consistency reliabilities ranged from good to excellent for all factors (Cronbach’s α =.80-.95). We retained four secondary maladaptive coping items (from an initial six), though these require further modification and testing (Cronbach’s α =.67).

Conclusion: The Behavioral Assessment Screening Tool for Adolescents, a measure of neurobehavioral symptoms after mild traumatic brain injury in adolescents, has a multidimensional factor structure with evidence of good internal consistency reliabilities. Future work will further evaluate its convergent and discriminant validity and employ item response theory analyses for validation in a new sample of adolescents with concussion.

摘要

目标：开发和验证青少年脑损伤行为评估筛查工具。

环境: 脑震荡诊所

参与者：初次脑震荡门诊就诊 3 个月后患有轻度创伤性脑损伤的青少年（n = 138）。

设计：评估开发和验证（横断面队列）研究

主要措施：行为评估筛查工具——青少年

结果：专家小组成员在最初的成人行为评估筛查工具中添加或修改了特定于青少年的项目。内容有效性指数为 97.2%。行为评估筛查工具的探索性因素分析——青少年将最初的 70 个项目减少到 46 个主要项目，并采用 3 因素解决方案：负面影响和疲劳、执行和社会功能以及风险行为。所有因素的内部一致性可靠性范围从良好到极好（Cronbach's α =.80-.95）。我们保留了四个次要的适应不良应对项目（来自最初的六个），尽管这些需要进一步修改和测试（Cronbach's α =.67）。

结论：青少年行为评估筛查工具是衡量青少年轻度创伤性脑损伤后神经行为症状的指标，具有多维因素结构，具有良好的内部一致性可靠性证据。未来的工作将进一步评估其收敛效度和判别效度，并在新的脑震荡青少年样本中采用项目反应理论分析进行验证。
