Abstract: Objective To classify and explore the characteristics of different types of suicide attempters in terms of the suicidal behaviors. Methods The demographic characteristics, psychosocial factors, and details of suicide attempts of 408 medically serious suicide attempters in rural areas of Shandong Province were collected by face-to-face interviews. Cluster analysis was performed using the two-step method. Results The suicide attempters fell into two types: 231(56.62%)in the impulsive cluster, characterized by low suicide intent, low lethality, and high impulsiveness; 177(43.38%)in the well-planned cluster, characterized by high suicide intent, high lethality, and more histories of attempted suicide. The well-planned group was associated with older age(P=0.003), mental illness(P<0.001), and higher depression and hopelessness(P<0.001). Conclusion Cluster analysis extracts two distinct groups of suicide attempters showing different patterns of suicidal behaviors. Targeted prevention strategies should be formulated for different groups.
