Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: Cluster randomization with stratification allocated groups selected by participating organizations to treatment and control groups. Primary stratification was by the organization. Within-organization stratification took into account the size, the type of work tasks and the response rate in the first survey of cluster. Participating organizations entered all together to 36 clusters, each with individuals for the intervention and active control groups (N=638 individuals). The intervention (and active control) receive different types of workshops, individual tasks and team tasks. Additional information is available from non-randomized passive control group (N=289 individuals).

Participating organizations were recruited by informing about the study. Participating units included knowledge workers, whose work tasks are cognitively rather than physically demanding.
Primary purpose: TREATMENT

Brief summary: 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.

Detailed description: 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.

Eligibility criteria: The participants in the study work in the participating organizations were recruited through direct contacts and by informing about the study in various events.

* The participating units (in organizations) include knowledge workers, such as office workers and experts

Whose

* work tasks are cognitively rather than physically demanding
