Results: Three RSiena models exhibited high goodness of fit in the structural effect part (The estimated values of the three reciprocity effect parameters were 1.7067, 1.07384, and 1.07401, respectively ). The estimated value of the in-degree effect parameter of smoking cessation behavior influenced by network structure was 0.0934.
