In Reply: Dr Hassan and colleagues first question whether the results of our study can be applied to other populations because of social, cultural, and economic covariates that could influence job strain. In an international comparison of job strain scales that was undertaken in 4 countries with different work cultures (United States, Canada-Quebec, the Netherlands, and Japan), substantial similarities were found across countries regarding means and standard deviations, as well as significant correlations among scales and between scales and sociodemographic variables,1 indicating that these psychosocial job characteristics tend to be similar across industrialized countries.
