Psychological strain was measured in 592 Naval personnel at four phases using the General Health Questionnaire (GHQ-12). The GHQ-12 Likert score was summed to generate a measure of cumulative strain, which was best predicted by the Cognitive Failures Questionnaire (CFQ) score, effort-reward imbalance and a measure of organisational commitment. Point strain at phase IV was best predicted by CFQ score, whereas need for recovery was best predicted by over-commitment to work role. Susceptibility to strain, both cumulatively over 2 years and 12 months in the future appears to depend on a cognitive factor measured by the CFQ. This factor was more strongly associated with strain than with fatigue. Psychosocial stress exposure at work played a lesser role in predicting cumulative and future strain, possibly because these stressors were of an acute nature. The findings are discussed with reference to recent research on attention and anxiety and some of the practical implications are considered. STATEMENT OF RELEVANCE: There is renewed interest in intrinsic variables that predict adverse reactions to occupational stress. The paper presents evidence that self-reported cognitive failure is a vulnerability factor for future episodes of psychological strain. The paper strengthens the conclusions of a previous article and adds empirical support to recent research on the links between anxiety and attention.
使用一般健康问卷（GHQ-12）在四个阶段测量了 592 名海军人员的心理压力。通过对 GHQ-12 的李克特评分进行求和，得出了累积压力的衡量标准，该标准可通过认知失误问卷（CFQ）评分、努力-回报失衡以及组织承诺度的衡量标准来最好地预测。第四阶段的即时压力可通过 CFQ 评分来最好地预测，而对工作角色的过度投入则可最好地预测恢复需求。在未来 12 个月内，2 年内的累积压力的易感性似乎取决于 CFQ 衡量的认知因素。该因素与压力的相关性强于与疲劳的相关性。工作中的心理社会压力暴露在预测累积和未来压力方面的作用较小，这可能是因为这些压力具有急性性质。该研究结果与最近关于注意力和焦虑的研究有关，并考虑了一些实际意义。相关性的说明：人们对预测职业压力不良反应的内在变量重新产生了兴趣。本文提供的证据表明，自我报告的认知失败是未来心理压力发作的脆弱性因素。本文加强了之前一篇文章的结论，并为最近关于焦虑和注意力之间联系的研究提供了经验支持。
