This study attempts to explore the strains that terror organization members experience prior to the training process in the organization. The primary goal of this research is to understand the relationship between the earlier experienced strains of terrorists and their violent behaviors. In the study a Turkish Hezbollah terror organization sample (N = 144) was utilized in the frame of Agnew's (1992) general strain theory. Initially, quantitative methods, such as bivariate analysis and multivariate analysis, were utilized to identify the cumulative effect of strains on the violent behaviors of terrorists. Later, by utilizing case studies with a qualitative approach the mediating effect of negative emotions (anger, frustration, depression and fear) were identified. This study found that among Turkish Hezbollah members, prior to joining the terrorist organization, individuals who experience higher levels of strain are more likely to perform violent acts when compared to individuals who experience lower levels of strain. This study affirmed earlier studies on strain-crime relationship. Moreover, utilized case studies support that negative emotions -specifically anger- mediate between strains and violent actions. In sum, this research retests and builds on Agnew's theory and argues that general strain theory can help terrorism studies to understand the sources of strains of terrorists and the effect of strains on their violent behavior.
