To examine the utility of the Mayo-Portland Adaptability Inventory-4th Edition Participation Index (M2PI) as a self-report measure of functional outcome following mild traumatic brain injury (mTBI) in US Military veterans.
Department of Veterans Affairs Polytrauma Rehabilitation Center specialty hospital.
On hundred thirty-nine veterans with a history of self-reported mTBI.
Retrospective cross-sectional examination of data collected from regular clinical visits.
M2PI, Neurobehavioral Symptoms Inventory with embedded validity measures, Posttraumatic Stress Disorder Checklist-Military Version.
Forty-one percent of the sample provided symptom reports that exceeded established cut scores on embedded symptom validity tests. Invalid responders had higher levels of unemployment and endorsed significantly greater functional impairment, posttraumatic stress symptoms, and postconcussive complaints. For valid responders, regression analyses revealed that self-reported functioning was primarily related to posttraumatic stress complaints, followed by postconcussive cognitive complaints. For invalid responders, posttraumatic stress complaints also predicted self-reported functioning.
Caution is recommended when utilizing the M2PI to measure functional outcome following mTBI in military veterans, particularly in the absence of symptom validity tests.
考察 Mayo-Portland 适应能力量表第四版参与指数（M2PI）作为一种自我报告的功能结果测量方法，用于评估美国退役军人中轻度创伤性脑损伤（mTBI）后的功能。
退伍军人事务部多发创伤康复中心专科医院。
139 名有自我报告 mTBI 病史的退伍军人。
从定期临床就诊中收集数据的回顾性横断面研究。
M2PI、嵌入有效性测量的神经行为症状清单、创伤后应激障碍检查表-军事版。
样本中有 41%的人提供的症状报告超过了嵌入症状有效性测试的既定临界值。无效应答者的失业水平更高，并报告了明显更大的功能障碍、创伤后应激症状和脑震荡后主诉。对于有效的应答者，回归分析显示，自我报告的功能主要与创伤后应激主诉有关，其次是脑震荡后认知主诉。对于无效应答者，创伤后应激主诉也预测了自我报告的功能。
在评估军事退役军人 mTBI 后的功能结果时，建议谨慎使用 M2PI，特别是在缺乏症状有效性测试的情况下。
