This study sought to empirically test one of the most widely cited perspectives relative to radicalization and the growth of social movements - Identity and Framing Theory. Identity and framing perspectives contend that radicalization towards violence can be theorized as a process which entails a journey, typically from a non- or less-radical identity and corresponding orientation, towards a more radical identity and corresponding orientation which enhances the likelihood of employing targeted forms of violence because the prospect of desired change is seen as laying outside the realm of legitimate modes of challenge and expression within the targeted institutional arena. As implied, a key component of the process is the adoption or evolution of a radical identity. The study collection includes 1 SPSS data file (ATS_NIJ_FRAMING_QUANTITATIVE_DATASET.sav, n=465, 16 variables) and 1 Excel data file (ATS_NIJ_FRAMING_QUALITATIVE_DATASET.xls, n=38, 17 variables).
