We have many studies that have estimated peer effects on attitudes and
behaviors for a variety of health behaviors.
There were a stream of studies using the classic Coleman, Katz & Menzel
Medical Innovation data (see Friedkin, Burt, Valente, & Van den Bulte).
I worked with teams that estimated these effects for a variety of behaviors,
examples include:
Contraception in which we get large adjusted odds ratios (AOR) (~8.0) for
encouragement by peers:
Valente, T.W., Watkins, S., Jato, M.N., Van der Straten, A., & Tsitsol, L.M.
(1997). Social network associations with contraceptive use among Cameroonian
women in voluntary associations. Social Science and Medicine, 45, 677-687.
Adolescent smoking, peers and best/close friends in which the AOR is about
2:
Alexander, C., Piazza, M. Mekos, D., & Valente, T. W. (2001). Peers,
schools, and adolescent cigarette smoking: An analysis of the national
longitudinal study of adolescent health. Journal of Adolescent Health, 29,
22-30.
Valente, T. W., Fujimoto, K., Soto, D., Ritt-Olson, A., & Unger, J. (2013).
A Comparison of Peer Influence Measures as Predictors of Smoking among
Predominately Hispanic/Latino High School Students. Journal of Adolescent
Health, 52, 358-364.
(also see the work of Ennett, Mercken, Gest, Kobus, Iannotti, Simmons-Morton
.... to name a few)
Physicians in which we get some large effect sizes (~15):
Gross, C.P., Cruz-Correa, M., Canto, M.I., McNeil-Solis, C., Valente, T.W.,
& Powe, N.R. (2002). The adoption of ablation therapy for Barrett’s
esophagus: A cohort study of gastroenterologists. American Journal of
Gastroenterology, 97, 279-286.
And some more modest ones that may be better specified:
Iyengar, R., Van den Bulte, C. & Valente, T. W. (2010). Opinion leadership
and contagion in new product diffusion. Marketing Science, 30, 195-212.
Injection drug users risky and protective behaviors (~15):
Valente, T. W., & Vlahov, D. (2001). Selective risk taking among needle
exchange participants in Baltimore: Implications for supplemental
interventions. American Journal of Public Health, 91, 406-411.
(also see the work of Friedman, Latkin, Morris, ... to name a few)
Of course effect sizes are quite dependent on how the variables are measured
and recorded.
Hope this helps.

Subject: Reported effect sizes of network effects impacting attitude and
behavior
***** To join INSNA, visit http://www.insna.org *****
Dear all,
I want to compare the effect sizes I found in my research (of network
effects impacting attitude and behavior) with empirically found effect sizes
in other studies. However, I am having a hard time finding SNA literature
reporting effect sizes in this context.
Does anybody know SNA literature that reports empirical effect sizes, when
describing social network effects impacting attitude and/or behavior? Thanks
for a short reply.
Mit freundlichen Grüßen
met vriendelijke groet,
kind regards,
