Nurses often encounter situations in which they are called upon to assist in post-suicide community interventions with teachers, church youth group leaders, and mental health professionals. Controlled studies of interventions to aid adolescents coping with the loss of a peer are lacking. The purpose of this study, conditioned by an unanticipated suicide in an ongoing research study, was to document changes in psychosocial competence of adolescent peer suicide survivors. Following a supportive community intervention, the peer survivor group was compared with a similar group of adolescents who did not experience peer suicide. Both groups were in the control condition of a larger nursing study of social competence-building. The survivor group had significantly greater self-efficacy immediately after the community intervention and 2 months later when contrasted with the comparison group. In addition, the survivor group reported greater social acceptance and job competence immediately after the community intervention. Correlated t-tests showed the survivor group had significant gains in problem-solving appraisal and global self-worth after the community intervention, but significant declines in global self-worth and scholastic competence 2 months after the intervention. The findings support the belief that community interventions are initially worthwhile in helping adolescents to cope with peer suicide, but continued supportive intervention may be needed to offset declines noted over time in areas such as self-worth and academics.
