Mental health problems are increasingly becoming one of the most serious and widespread public health issues in the world. The rise and popularity of social network brings a lot of data related to psychological state of its users. The research of applying social network data to automatically evaluate and detect users' mental health status has attracted more and more scholars in recent years. This paper reviews the relevant literature on the automatic assessment of mental health for social network users. Based on the existing literature, we sum up the concept and definition of automatic assessment of mental health, review the related researches at home and abroad from different aspects of assessment task, social network data-sets construction, the characteristics used in the assessment and so on. The characteristics of existing methods including feature engineering based methods and deep learning basedmethods are compared. Finally, we discuss the problems and challenges for this task, including assessment performance, data quality, privacy ethics, reason extraction and automatic intervention. Future research is suggested to combine other data streams and collaborate between patients, clinicians and data scientists to apply machine learning in causation extraction, prevention and counseling of mental health problems.
