Israel's year-long protest calling for Prime Minister Netanyahu's resignation created an opportunity to examine unique factors influencing sustained collective action (SCA; i.e., repeated participation in social movement action for the same cause). As little is known about how to explain such dedication, we compared a well-established set of predictors of one-time collective action (CA) with a new predictors set of SCA, focusing on collective instrumental and socio-emotional (CISE) motivations grounded in previous participation experience, to predict subsequent participation. In a unique longitudinal design, we tracked protestors over 6 weeks. Our findings showed that less emotional exhaustion, more subjective effort into participation, and a perceived closer timeframe for desired social change positively predicted SCA. This differentiates SCA from CA-moreover, as one-time CA predictors did not predict SCA, this suggests a need for a new model to explain SCA based on CISE motivations that reflect continuous goal pursuit.
