Cognitive functioning is a relevant work and health related topic, however, validated methods to assess subjective cognitive complaints (SCC) at work are lacking. We introduce the Cognitive Function at Work Questionnaire (CFWQ) for measuring SCC in occupational settings. 1-year follow-up data of 418 employees from a Finnish public media service company was analyzed. Participants completed web-based CFWQ, cognitive tests and a broad set of questionnaires for evaluating depression, anxiety, insomnia, daytime sleepiness, burnout, stress, mental job burden, work ability, cognitive errors, and perceived health. The factor analysis yielded a model with the CFWQ subdomains: Memory, Language, Executive Function, Speed of Processing, Cognitive Control and Name Memory. The internal consistency (Cronbach's alpha = .87) and the test-retest constancy (ICC = .84) reflected good reliability. Correlation between the CFWQ and cognitive errors at work ranged from .25 to .64 indicating adequate concurrent validity. Employees with depression, insomnia and burnout symptoms had higher ( < .001) CFWQ scores than participants without these symptoms. Depression and burnout symptom severity as well as accumulation of mood, sleep, and psychosocial stressors were associated with higher CFWQ scores ( < .001 in all). The CFWQ appears psychometrically sound measure for the assessment of SCC in occupational population.
认知功能是一个与工作和健康相关的重要话题，然而，目前缺乏在工作中评估主观认知主诉（SCC）的有效方法。我们引入了工作中的认知功能问卷（CFWQ）来测量职业环境中的SCC。对一家芬兰公共媒体服务公司的418名员工的1年随访数据进行了分析。参与者完成了基于网络的CFWQ、认知测试以及一系列用于评估抑郁、焦虑、失眠、日间嗜睡、倦怠、压力、心理工作负担、工作能力、认知错误和感知健康的问卷。因子分析得出了一个包含CFWQ子领域的模型：记忆、语言、执行功能、处理速度、认知控制和姓名记忆。内部一致性（克朗巴哈α系数 =.87）和重测稳定性（组内相关系数ICC =.84）反映出良好的信度。CFWQ与工作中的认知错误之间的相关性在.25至.64之间，表明具有足够的同时效度。有抑郁、失眠和倦怠症状的员工的CFWQ得分高于没有这些症状的参与者（<.001）。抑郁和倦怠症状的严重程度以及情绪、睡眠和心理社会压力源的累积与较高的CFWQ得分相关（均<.001）。CFWQ似乎是一种在心理测量学上可靠的工具，可用于评估职业人群中的SCC。
