programs and professionals in disciplines such as psychiatric
rehabilitation.36,38 Further, most employees who transfer from
state-owned enterprises or migrate from rural areas to work in
private enterprises often need to adapt and adjust to different
management systems and an ‘‘enterprise culture.’’ This situ-
ation also may contribute to stress and depression among
these employees. However, few studies have empirically ex-
amined depression and its relation to employees’ productivity
in these enterprises. Furthermore, few intervention or treat-
ment programs have been made available in the enterprise
context in China to assist depressed employees. The present
study aims to address this research gap by examining the
effectiveness of a workplace-based intervention program
aimed at improving employees’ mental health and job per-
formance in a private enterprise through the use of a com-
prehensive and multilevel health promotion framework that
addresses a number of job-related risk factors.
