Further investigation of the DISC-model: results of an internet study among various occupational groups. R. de Bruin, F. van Boxmeer, C. Verwijs & P. Le Blanc, Gedrag & Organisatie, volume 20, September 2007, nr. 3, pp. 238-259 In this crosssectional internet study, the compensation principle of the Demand-Induced Strain Compensation (DISC)-model was subjected to an empirical verification among 390 employees from various economical sectors. The DISC-model assumes a positive causal relationship between work-related stressors and strains on three qualitatively different domains (cognitive, emotional and physical). According to the compensation principle, these causal relationships are moderated by the availability and use of (matching) work-related resources from the same domain. The results of hierarchical multiple regression analyses did not support the compensation principle. Moreover, a large number of cross-domain correlations were found, especially with regard to emotional resources. The results of this study show that more research on the principles of the DISC-model should is needed. Implications of the use of the internet for research on work stress are discussed.
