Issue-based micromobilization on social media: Mediated pathways linking issue involvement and self-network opinion congruity to expressive support

作者：

Highlights：

• Strong explanation of expressive support (about 90.1% and 74.9%) between different individual-group issue positions.

• Individual-group identification strongest mediator of personal issue involvement on expressive support.

• Participative efficacy strongest predictor of likelihood to express support for ideologically-consonant group.

• Influence of perceived self-network opinion congruity and participative efficacy depends on individual issue positions.

• Need for future mobilization research to consider issue-group positions and counter-group dynamics on social media.
