■行为控制异常通常发生在普通人群和美国服役人员和退伍军人(SM/V)中。这种情况在SM/V中值得特别注意,特别是在部署之后。军事部署经常引起创伤后应激障碍(PTSD)和部署相关的轻度TBI创伤性脑损伤(TBI),可能导致行为失控的表现。
■检查PTSD症状严重程度之间的关联,部署相关的轻度创伤性脑损伤,SM/V之间的行为控制失调
■来自军事相关脑损伤联盟的长期影响-神经创伤联盟在SM/V(N=1,808)中的前瞻性纵向研究的二级横截面数据分析。
■单变量和多变量线性回归模型评估了PTSD症状严重程度之间的关联和相互作用效应,根据诊断和统计手册的创伤后应激障碍清单评估,第5版(PCL-5),和部署相关的轻度TBI对行为控制异常,适应人口统计,疼痛,社会支持,弹性,和一般的自我效能感。
■在我们样本中的1,808个人中,在单变量分析中,PTSD症状严重程度(B=0.23,95%CI:0.22,0.25,p<0.001)和部署相关的轻度TBI(B=3.27,95%CI:2.63,3.90,p<0.001)与行为控制异常显着相关。在多变量分析中,PTSD症状严重程度与部署轻度TBI之间的交互作用显着(B=-0.03,95%CI:-0.06,-0.01,p=0.029),表明轻度TBI对行为控制的影响在PCL-5评分>22.96的人群中不再显著。
■结果表明PTSD症状严重程度之间存在关联,部署相关的轻度TBI,SM/V之间的行为控制失调值得注意的是,对于PTSD症状严重程度较低的个体,部署相关的轻度TBI的影响显著.较高的社会支持分数与较低的失控有关,强调社会支持可能成为保护因素。一般自我效能感也与行为控制失调减少有关。
UNASSIGNED: Behavioral dyscontrol occurs commonly in the general population and in United States service members and Veterans (SM/V). This condition merits special attention in SM/V, particularly in the aftermath of deployments. Military deployments frequently give rise to posttraumatic stress disorder (PTSD) and deployment-related mild TBI traumatic brain injury (TBI), potentially leading to manifestations of behavioral dyscontrol.
UNASSIGNED: Examine associations among PTSD symptom severity, deployment-related mild traumatic brain injury, and behavioral dyscontrol among SM/V.
UNASSIGNED: Secondary cross-sectional data analysis from the Long-Term Impact of Military-Relevant Brain Injury Consortium - Chronic Effects of Neurotrauma Consortium prospective longitudinal
study among SM/V (N = 1,808).
UNASSIGNED: Univariable and multivariable linear regression models assessed the association and interaction effects between PTSD symptom severity, as assessed by the PTSD Checklist for the Diagnostic and Statistical Manual, 5th edition (PCL-5), and deployment-related mild TBI on behavioral dyscontrol, adjusting for demographics, pain, social support, resilience, and general self-efficacy.
UNASSIGNED: Among the 1,808 individuals in our sample, PTSD symptom severity (B = 0.23, 95% CI: 0.22, 0.25, p < 0.001) and deployment-related mild TBI (B = 3.27, 95% CI: 2.63, 3.90, p < 0.001) were significantly associated with behavioral dyscontrol in univariable analysis. Interaction effects were significant between PTSD symptom severity and deployment mild TBI (B = -0.03, 95% CI: -0.06, -0.01, p = 0.029) in multivariable analysis, indicating that the effect of mild TBI on behavioral dyscontrol is no longer significant among those with a PCL-5 score > 22.96.
UNASSIGNED: Results indicated an association between PTSD symptom severity, deployment-related mild TBI, and behavioral dyscontrol among SM/V. Notably, the effect of deployment-related mild TBI was pronounced for individuals with lower PTSD symptom severity. Higher social support scores were associated with lower dyscontrol, emphasizing the potential for social support to be a protective factor. General self-efficacy was also associated with reduced behavioral dyscontrol.
