| Abstract (English): |
Posttraumatic stress disorder (PTSD) has been consistently linked to poorer functional outcomes, including quality of life, health problems, and social and occupational functioning. Less is known about the potential mechanisms by which PTSD leads to poorer functional outcomes. We hypothesized that neurocognitive functioning and perception of cognitive problems would both mediate the relationship between PTSD diagnosis and functioning. In a sample of 140 veterans of the recent wars and conflicts in Iraq and Afghanistan, we assessed PTSD symptoms, history of traumatic brain injury (TBI), depression, self-report measures of quality of life, social and occupational functioning, and reintegration to civilian life, as well as perception of cognitive problems. Veterans also completed a comprehensive neuropsychological battery of tests. Structural equation modeling revealed that perception of cognitive problems, but not objective neuropsychological performance, mediated the relationship between PTSD diagnosis and functional outcomes after controlling for TBI, depression, education, and a premorbid IQ estimate, b = -6.29, 95% bias-corrected bootstrapped confidence interval [-11.03, -2.88], showing a large effect size. These results highlight the importance of addressing appraisals of posttrauma cognitive functioning in treatment as a means of improving functional outcomes. [ABSTRACT FROM AUTHOR] |

Resumen La Percepción de Problemas Cognitivos, y no el Rendimiento Neuropsicológico Objetivo, Media la relación entre TEPT y Resultados Funcionales PERCEPCIÓN DE PROBLEMAS COGNITIVOS EN TEPT El trastorno de estrés postraumático (TEPT) se ha vinculado de forma consistente a peores resultados funcionales, incluyendo calidad de vida, problemas de salud y el funcionamiento social y ocupacional. Menos conocidos son los mecanismos potenciales por los cuales el TEPT conduce a peores resultados funcionales. Hipotetizamos que el funcionamiento neurocognitivo y la percepción de los problemas cognitivos podrían mediar la relación entre el diagnóstico de TEPT y el funcionamiento. En una muestra de 140 veteranos de las recientes guerras y conflictos en Irak y Afganistán, evaluamos síntomas del TEPT, historia de lesión cerebral traumática (TBI), depresión, medidas de auto-reporte de calidad de vida, del funcionamiento laboral y social, y la reintegración en la vida civil, así como la percepción de problemas cognitivos. Los veteranos también completaron una batería de pruebas neuropsicológicas exhaustiva. El modelo de ecuaciones estructurales reveló que la percepción de problemas cognitivos, pero no el funcionamiento neuropsicológico objetivo, media la relación entre el diagnóstico de TEPT y los resultados funcionales después de controlar por TBI, depresión, educación y un coeficiente intelectual premórbido estimado (B = -6,29, intervalo de confianza bootstrapped corregido por sesgo de 95%: [-11,03, -2,88]), mostrando un gran tamaño del efecto (k2 = .26). Estos resultados destacan la importancia de abordar la evaluación del funcionamiento cognitivo post-trauma en el tratamiento, como un medio para mejorar los resultados funcionales.

抽象 Perception of Cognitive Problems, Not Objective Neuropsychological Test Performance, Mediates Relationship between PTSD and Functional Outcomes Traditional Chinese 標題: 對認知問題的感知在PTSD和功能運作的關係有中介效應, 客觀的神經心理表現則無構成中介 撮要: 過往研究一致發現創傷後壓力症(PTSD)跟生活質素、健康、社交和事業運作等功能受損有關。然而, 我們對PTSD導致功能受損的潛在機制認識不足。本研究假設神經認知運作和對認知問題的感知, 兩者都會在PTSD和功能運作的關係間構成中介效應。樣本為近年於伊拉克和阿富汗服役的140名退役軍人。我們檢視樣本的PTSD症狀、過往的創傷性腦損傷(TBI)記錄、抑鬱症、對生活質素的自評、社交和事業運作、重投平民生活的狀況、及對認知問題的感知。樣本亦接受了一系列綜合的神經心理測量。結構方程模型反映, 我們對樣本的TBI、抑鬱症、教育和患病前的IQ估計作對照試驗後, 對認知問題的感知在PTSD診斷和功能運作的關係有中介效應(B = -6.29, 95% 已修正偏差、拔靴帶置信水準: [-11.03, -2.88]), 效應量大(K2 = .26);但客觀的神經心理表現則無構成中介。結果反映, 為改善患者的功能運作, 我們有需要在治療裡評估和跟進患者創傷後的認知運作。 Simplified Chinese 标题: 对认知问题的感知在PTSD和功能运作的关系有中介效应, 客观的神经心理表现则无构成中介 撮要: 过往研究一致发现创伤后压力症(PTSD)跟生活质素、健康、社交和事业运作等功能受损有关。然而, 我们对PTSD导致功能受损的潜在机制认识不足。本研究假设神经认知运作和对认知问题的感知, 两者都会在PTSD和功能运作的关系间构成中介效应。样本为近年于伊拉克和阿富汗服役的140名退役军人。我们检视样本的PTSD症状、过往的创伤性脑损伤(TBI)记录、抑郁症、对生活质素的自评、社交和事业运作、重投平民生活的状况、及对认知问题的感知。样本亦接受了一系列综合的神经心理测量。结构方程模型反映, 我们对样本的TBI、抑郁症、教育和患病前的IQ估计作对照试验后, 对认知问题的感知在PTSD诊断和功能运作的关系有中介效应(B = -6.29, 95% 已修正偏差、拔靴带置信水平: [-11.03, -2.88]), 效应量大(K2 = .26);但客观的神经心理表现则无构成中介。结果反映, 为改善患者的功能运作, 我们有需要在治疗里评估和跟进患者创伤后的认知运作。 [ABSTRACT FROM AUTHOR] |
