Psychological empowerment has attracted attention in the past 20 years from both researchers and practicers for its important role in an organization’s development. In the previous literature, different opinions on the structure of psychological empowerment have been put forward, including the single-dimension concept, three-dimension concept, four-dimension concept and six-dimension concept. In respect of its antecedent variables, researchers have examined the effects of individual (mainly including socioeconomic variables and personality variables) and organizational variables on psychological empowerment. As to its outcome variables, previous studies have found that psychological empowerment is positively related with individuals` job satisfaction, profession commitment, organization commitment, performance and mental health, but inconsistent findings still exists in the respect of the influence of psychological empowerment’s dimensions on these outcomes . Based on comprehensive analysis on literature, the limitations in the present domain of psychological empowerment were put forward, and the directions and advices for future study were also given.
