简要总结
The main aim of the SujuKE study is to test the effectiveness of workplace cognitive ergonomics development program designed to decrease cognitively disrupting work conditions and work-related cognitive stress, and to improve work flow. The cognitive ergonomics workplace intervention includes cognitive ergonomics workshop, work experiments, and intervention task questionnaires. Its effect on changes in subjective measures of work conditions, work flow, stress, and work productivity will be studied. The hypothesis is that cognitive ergonomics intervention decreases the level of cognitive strain related to work conditions, and this change is associated with higher level in work flow, well-being, and productivity at work.
详细描述
In the modern work life, performing work tasks rely on cognitive function, i.e. mental processes that are involved in processing information, such as attention, working memory, decision making and learning. Furthermore, the conditions at work include situations that require cognitive capacity. Information overload, multitasking and interruptions are typical features in any work. Thus, in the modern work life, work is knowledge work or information work by nature, and cognitive strain is a notable psychosocial risk factor. Not only task demands per se can exceed natural limitations of human cognitive capacities, but also the conditions at work can make it demanding for a human to perform.
Research shows that psychosocial stress, including cognitive stress, challenges wellbeing, safety and productivity at work. Cognitively straining conditions, such as disruptions, interruptions and information overload are related to higher levels of work stress, occupational accidents, and cognitive failures at work. It is essential to decrease harmful consequences to individual workers, organizations, and the society by managing psychosocial risks typical to cognitively demanding work tasks and conditions.
SujuKE study focuses on ergonomics (or human factors) practices that aim to ensure 'appropriate interaction between work, product and environment, and human needs, capabilities and limitations'. In cognitive ergonomics, the focus is on making human-system interaction compatible with human cognitive abilities and limitations, particularly at work. The aim is to apply general principles and good practices of cognitive ergonomics that help to avoid unnecessary cognitive load at work and that improve human performance.
The aim of the SujuKE study is to improve the conditions of knowledge work and promote the flow of work and reduce work strain. There are studies which show that decreasing disruptions, providing uninterrupted working time, and reducing information may lead to improved work flow and productivity. In the SujuKE-study, several sources of cognitive strain are restricted and concrete methods to help improve cognitive ergonomics will be worked on and implemented at workplace. The objective of the project is to obtain research evidence of the effects of cognitive ergonomics development programme on working conditions, the flow of work, well-being at work, and the productivity at work.
During the SujuKE project, the investigators will implement measures at the workplace that aim to facilitate work and reduce strain. The objective of the project is to obtain research evidence of the effects of these measures on working conditions, the flow of work, well-being at work, and the productivity at work. The study is carried out by the Finnish Institute of Occupational Health (FIOH) and funded by the Finnish Work Environment Fund.

结局指标
主要结局
Change in cognitive strain prevalence
时间窗: 1: Baseline measurements: 10-16 weeks before the intervention phase. 2: End-of-treatment measurements: 18-28 weeks after the baseline measurements. 3: Follow-up 4m: 16 weeks after the end-of-treatment. 4: Follow-up 10m: 40 weeks after end-of-treatment
Cognitive strain prevalence measures prevalence of disruptions, interruptions, and information overload. There are two items on disruptions, three items on interruptions, and seven items on information overload including memory load, multitasking, and problems with instructions (Brain@Work survey by FIOH). Response scale is from 1 to 5, higher number indicating higher prevalence (Scale: More rarely; Monthly; Weekly; Daily, or almost daily; Many times a day) Total score is a factor score including all 12 items.
