Identifying different 'types' of participants in the Chilean student movement: A latent transition analysis of collective action intentions, social class and movement identification.

Around the world, we witness not only growing levels of economic inequality but also the rise of protests whereby people from different social classes are demanding a more equal society. Our research uses a person‐centered approach to examine subgroups of participants in a social movement against inequality on the basis of their social class, intention to participate in conventional and/or radical collective actions, and social identification with the movement. We used longitudinal data from the Chilean student movement (two time points; total N = 1226) to conduct latent profile and latent transition analysis. We identified four profiles of participants: (1) inactive supporters (mostly from the upper class), (2) low radicals (mostly from the middle class), (3) moderate radicals (mostly from the middle class), and (4) high radicals (mostly from the middle class). The four profiles were generally stable over the one‐year period. We further found that group efficacy and a "nothing to lose" mindset predicted the profile membership of participants. Group efficacy also predicted transitions of participants between different profiles. Our findings highlight the key role that the middle class plays in diverse forms of collective action.
