Although the relationship between negative affect and psychiatric symptoms has been well-demonstrated in research, less is known about positive affect relative to negative affect, and its relationship to psychiatric symptoms, especially among veterans. This study examined how levels of positive and negative affect are associated with symptoms of depression, anxiety, and posttraumatic stress disorder (PTSD). Data were collected in a veteran polytrauma clinic; analyses were conducted using data from 94 veterans (87 males) with and without a mild traumatic brain injury (mTBI) diagnosis. Results demonstrate that positive and negative affect were separate dimensions and that both were independently related to each symptom measure. After removing the contribution of negative affect from symptom reports, strong relationships remained between positive affect and psychiatric symptoms. Furthermore, the magnitude of the associations for positive affect and for negative affect with symptoms of depression, anxiety, and PTSD were not impacted by a mTBI diagnosis. Altogether, findings suggest that both positive and negative affect should be uniquely considered when conceptualizing, assessing, and treating returning service members; in addition, positive affect may be an appropriate target of assessment and interventions of persons who have experienced polytrauma.
尽管研究已充分证明消极情绪与精神症状之间的关系，但相对于消极情绪，积极情绪及其与精神症状的关系，尤其是在退伍军人中，所知甚少。本研究探讨了积极情绪和消极情绪水平如何与抑郁、焦虑和创伤后应激障碍（PTSD）症状相关联。数据收集于一家退伍军人多创伤诊所；分析使用了94名有或无轻度创伤性脑损伤（mTBI）诊断的退伍军人（87名男性）的数据。结果表明，积极情绪和消极情绪是不同的维度，且二者均独立与各症状指标相关。从症状报告中去除消极情绪的影响后，积极情绪与精神症状之间仍存在强关联。此外，mTBI诊断并未影响积极情绪和消极情绪与抑郁、焦虑和PTSD症状之间关联的强度。总之，研究结果表明，在对退伍军人进行概念化、评估和治疗时，应分别考虑积极情绪和消极情绪；此外，积极情绪可能是经历多创伤者评估和干预的合适目标。
