Table H.1.5. Study #5: Nytro, K., Saksvik, P., and Torvatn, H. Organizational prerequisites for the implementation of systematic health, environment and safety work in enterprises, Safety Science. 1998; 30(3): 297-307.
To learn more about the necessary requirements (organizational factors) for achieving successful implementation of Internal Control (IC) of health, environment and safety (HES).
Experimental Design: BEFORE-AFTER STUDY
Cross-sectional surveys done in 1993 (shortly after regulation) and in 1996. Sample Characteristics:
In each of 1993 and 1996, randomized quota samples of private and public enterprises were selected to represent the distribution of Norwegian firms according to size, industry and geographical location. In 1993, n = 2092; in 1996 n = 1182. Refusal rate not given. Size of workplaces in 1996: 43% had <10 employees; 39% had <100; 18% had >100.
Maintenance of Sample: Not applicable.
Intervention: MANDATORY OHSMS
1992 regulation in Norway claiming all enterprises should implement Internal Control (IC) of health, environment and safety (HES) work. Must undertake systematic actions (at enterprise level) to ensure and document that the activities for the continuous betterment of HES are accomplished in accordance with requirements specified in laws and regulations. The systematic actions are to be described as administrative procedures.
Data Collection, Data Transformation, and Measurement Properties:
Implementation was measured by means of a cross-sectional survey (computer-assisted telephone interviews) of enterprises. Each enterprise had one respondent. The publication does not mention how
respondents were selected, but they were most often managers (34% firm managers, 15% middle management, 12% managers responsible for health, environment and safety). The authors are unclear about the derivation of the implementation measure in Table 2, but with the aid of Saksvik and Nytro (1996) and Gaupset (2000), Saksvik et al (2003) we can deduce that it is based on a self-assessment of internal control implementation status ranging from “not started” to “finished” on a five point scale. The five categories are collapsed into three: implemented, implementation in progress, not started yet. The percentage of enterprises in each category is reported.
Statistical Tests: Not applicable (none conducted).
