**4. Conclusion**

An overview of workaholism has been provided in this section. Despite a high prevalence of workaholism among the working population, not much is known about the issue. There is still not a consensus on its definition from the basis of science. The reasons people are driven into workaholism are relatively numerous and quite complex, including obsessive-compulsiveness, perfectionism, narcissism, sociocultural environment, and family and organizational characteristics (and so on). It appears that there is a great need for longitudinal and randomized control design studies for observing and examining the behaviors and health of workaholics.
