Note. Data were analyzed using block sequential logistic regressions. N = 62. Sex was dropped from the analyses for first week smoking because the model would not converge due to problems with multicollinearity. Perceived responsiveness marginally predicts final week smoking when satisfaction is omitted from the model, OR = 0.61, 95% CI = [0.35, 1.06],p = .079. OR = odds ratio; 95% CI = 95% confidence interval.
