Abstract

Objective: While psychiatric disorders (e.g., depression, anxiety) are well-established predictors of suicidal ideation (SI) in individuals with traumatic brain injury (TBI), the roles of other psychological and cognitive factors remain underexplored. This study examined associations between SI and emotion-processing difficulties, coping strategies, psychological resilience, and cognitive functioning after moderate-severe TBI.

Method: This was a secondary analysis of data from 106 individuals with moderate-severe TBI. SI and emotional distress were assessed using the Inventory of Depression and Anxiety Symptoms and Hospital Anxiety and Depression Scale, respectively. Participants also completed measures of emotional lability and detachment (Comprehensive Assessment of Traits Relevant to Personality Disorders [CAT-PD]), coping (Coping Scale for Adults), psychological resilience (Connor-Davidson Resilience Scale), and cognitive functioning, including subjective (CAT-PD, Brief Rating of Executive Function) and objective measures (Brief Test of Adult Cognition by Telephone). Spearman's correlations and path models were used to examine psychological and cognitive correlates of SI.

Results: SI was positively associated with emotional lability, emotional detachment, non-productive coping, and self-reported cognitive problems, and negatively associated with resilience. Path models indicated that emotional distress accounted for 76-100% of these associations. Conversely, SI was not significantly associated with adaptive coping or objective cognitive performance.

Conclusions: Emotion-processing difficulties, non-productive coping strategies, low resilience, and self-reported cognitive problems are linked to SI in individuals with moderate-severe TBI, primarily through their associations with emotional distress. Findings underscore the importance of addressing emotional distress, including depression and anxiety, and its underlying contributors in suicide prevention for this population.

创伤性脑损伤后自杀意念的心理和认知相关。

目的：虽然精神疾病（如抑郁、焦虑）是创伤性脑损伤（TBI）患者自杀意念（SI）的公认预测因素，但其他心理和认知因素的作用仍未得到充分探讨。本研究考察了中重度脑外伤后SI与情绪处理困难、应对策略、心理弹性和认知功能之间的关系。方法：这是对106例中重度TBI患者数据的二次分析。SI和情绪困扰分别使用抑郁和焦虑症状量表和医院焦虑和抑郁量表进行评估。参与者还完成了情绪不稳定性和超脱（人格障碍相关特征综合评估[CAT-PD]）、应对（成人应对量表）、心理弹性（康纳-戴维森弹性量表）和认知功能的测试，包括主观测试（CAT-PD，执行功能简要评定）和客观测试（成人电话认知简要测验）。斯皮尔曼的相关性和路径模型被用来检查心理和认知相关的SI。结果：SI与情绪不稳定性、情绪超脱、非生产性应对和自我报告的认知问题呈正相关，与弹性呈负相关。路径模型表明，情绪困扰占这些关联的76-100%。相反，SI与适应性应对或客观认知表现没有显著关联。结论：情绪处理困难、非生产性应对策略、低恢复力和自我报告的认知问题与中重度TBI患者的SI有关，主要是通过他们与情绪困扰的关联。研究结果强调了解决情绪困扰的重要性，包括抑郁和焦虑，以及它对这一人群自杀预防的潜在影响。

期刊介绍： The Journal of the International Neuropsychological Society is the official journal of the International Neuropsychological Society, an organization of over 4,500 international members from a variety of disciplines. The Journal of the International Neuropsychological Society welcomes original, creative, high quality research papers covering all areas of neuropsychology. The focus of articles may be primarily experimental, applied, or clinical. Contributions will broadly reflect the interest of all areas of neuropsychology, including but not limited to: development of cognitive processes, brain-behavior relationships, adult and pediatric neuropsychology, neurobehavioral syndromes (such as aphasia or apraxia), and the interfaces of neuropsychology with related areas such as behavioral neurology, neuropsychiatry, genetics, and cognitive neuroscience. Papers that utilize behavioral, neuroimaging, and electrophysiological measures are appropriate. To assure maximum flexibility and to promote diverse mechanisms of scholarly communication, the following formats are available in addition to a Regular Research Article: Brief Communication is a shorter research article; Rapid Communication is intended for "fast breaking" new work that does not yet justify a full length article and is placed on a fast review track; Case Report is a theoretically important and unique case study; Critical Review and Short Review are thoughtful considerations of topics of importance to neuropsychology and include meta-analyses; Dialogue provides a forum for publishing two distinct positions on controversial issues in a point-counterpoint format; Special Issue and Special Section consist of several articles linked thematically; Letter to the Editor responds to recent articles published in the Journal of the International Neuropsychological Society; and Book Review, which is considered but is no longer solicited.
