An Occupational Job Strain Index based on five Norwegian nationwide surveys of living conditions on work environment

OBJECTIVES: This paper aims to provide comprehensive documentation of the Occupational Job Strain Index (JSI), developed using data from the Norwegian nationwide Survey of Living Conditions conducted in 2006, 2009, 2013, 2016, and 2019. The JSI, based on Karasek's Demand-Control Model, offers detailed information on working conditions, addressing a gap in national register data. The surveys, including information on the psychosocial working environment, contributed to the development of the JSI through self-reported information and psychosocial exposure items by Statistics Norway (SSB). DATA DESCRIPTION: This paper includes the scripts documenting the construction of the Psychosocial Job Exposure Matrix and the Occupational Job Strain Index (Data File 1), along with a script containing the key for converting 4-digit STYRK-08 codes into 4-digit STYRK-98 codes and the procedure for merging the index with register data (Data File 2). Data File 3 contains the complete Psychosocial Job Exposure Matrix and Occupational Job Strain Index. Data File 4 includes a full codebook.
