Conclusion
Our study shows that the benefits of GC-CCP on alter uptake of CC screening are enhanced by the recipient of advocacy increasing her own advocacy for CC prevention and screening. The GC-CCP intervention had strong effects on nearly all components of the intervention, including index participants’ engagement in prevention advocacy. However, it was the alters’ engagement in prevention advocacy themselves that fully mediated the effect of the intervention on alter screening. The intervention effects on increased engagement in CC prevention advocacy and CC knowledge, among both index and alter participants, suggest a potential diffusion of advocacy and CC information throughout the network, which bodes well for CC screening activation throughout the network and the larger community.
