You're absolutely bang-on with the cultural dependence thing. Here, in Europe (although this seems to be changing), it's normal to work fewer hours than would be customary in North America. So, your threshold for 'workaholism' would be lower. I'm not sure if this is a Western thing or whatever it might be, but for some reason a lot of social science researchers neglect to mention that their research is done on a specific cultural group. You could say "... in the US" for this title, but I rarely see this done.
