This study aimed to examine the role that informal and formal social support play with psychological well-being as reflected in positive and negative emotions of injured terror survivors in Israel. A total of 150 survivors who were eligible for social support and assistance by government agencies completed questionnaires that examined positive and negative emotions, informal social support, and formal social support from public government agencies provided by professional trained social workers. A hierarchal regression demonstrated that informal social support is associated with improved psychological state. However, formal social support, although provided by professional agencies, failed to demonstrate such an association. Theoretical, clinical, and policy implications of the findings are discussed.
