This study examined whether quantitative content analysis of the value references, motive imagery, and integrative complexity expressed in the documents of two terrorist groups and two nonterrorist comparison groups could distinguish the violent groups from their nonviolent counterparts. The two terrorist groups were Central al Qa'ida and al Qa'ida in the Arabian Peninsula. For each, a comparison group that operated in the same context and had a similar ideology but did not engage in terrorist violence was chosen. Statistical analyses revealed that, compared with their nonterrorist counterparts, both terrorist groups described themselves by using more positive morality, religion, and aggression value references, and described their enemies by using more negative religion value references (e.g., references to being infidels). Relative to their nonviolent comparison groups, terrorist groups also used more power, ingroup affiliation, and achievement motive imagery, and expressed lower levels of integrative complexity.When people communicate, they often convey more than the explicit content of their words. Indeed, psychological research using content analytic techniques to examine value demonstrated the importance of attending not only to what people say but how they say it. The purpose of this paper is to analyze the communications of two terrorist groups and two comparison groups along these lines. In doing so, it builds upon and expands previous research examining the relationship between group rhetoric and terrorist violence (Smith, 2004;2008).During the past several decades, research on political violence has demonstrated that several quantitative content analysis coding systems provide scientifically rigorous and valid means of exploring the complex relationship between violent words and violent actions. Psychological variables related to individuals' and groups' values, motives, and quality of information processing have been coded in documents and found to be
