“This study investigated the relationships between the level of implementation of IC as a predictor variable and the satisfaction of workers at motor vehicle repair garages with the HES activities and working environment of the garages, participation in HES activities, coping with musculoskeletal symptoms, occurrence of musculoskeletal symptoms and sick leave as separate outcome variables.”
Experimental Design: CROSS-SECTIONAL STUDY
Cross-sectional study with data collected in 1996. Sample Characteristics:
SAMPLE SIZE: 1567 managers and garage workers in 237 garages
TYPE OF INDUSTRY: Industry code 8111 - Automotive repair
SIZE OF WORKPLACES:
< 10 employees: 41%
10-30 employees:42% >30 employees: 17% Mean 18; median 12; SE 20; range 2-140 employees NUMBER OF WORKPLACES: 311 initially sampled; 237 agreed to participate
panel beaters or sprayers
supervisors or foremen
SAMPLING METHOD: Convenience sample plus other participants, some of whom were matched group. 130 member garages of the Norwegian Association of Motorcar Dealers and Service Organization that were scheduled to participate in a management training course in health and safety were recruited, as well as 181 other Association members including 130 who had been matched to the training course participants in terms of size and geographic location. Questionnaires were distributed to supervisors/managers./ safety directors at the 311 selected garages, 250 were returned, and 237 companies agreed to participate. A total of
2174 questionnaires were distributed to managers and garage workers at the 237 firms, and
1567 were returned.
98% were male
36% were union members
Maintenance of Sample: Maintenance of the sample is not an issue due to the cross-sectional design.
Intervention: MANDATORY OHSMS
In January 1992, Internal Control Regulation, a new regulation on health and safety management, came into force in Norway. All private and public companies were required to act systematically to ensure health, environment and safety (HES) activities. IC was defined as: systematic action (at the company level) to ensure and document that the activities of health, environment and safety control are performed in accordance with requirements specified in acts or regulations (such as the Working Environment Act of 1977). The systematic action must be described as administrative procedures.” Regulation emphasizes that the employer is responsible for the company’s HES activities, that the workers must be encouraged to participate in those activities, and that each company may adjust its HES management system to its needs and special risk factors. Each company is required to
