Note: Significant client language effects denoted with bold face (p<0.05). M = mean, SD = standard deviation, OR = odds ratio, CI = confidence intervals, d = standardized mean difference = standardized beta coefficient for the multivariate model: outcome ~ change talk + learn talk. CT & LT coded (0,1) and analyzed using generalized linear modeling, function glm(), in the R statistical platform. Measures defined in the text.

^aAny quit attempt made during follow-up, n= 107 & 78 for CT and 88 & 97 for LT.

^bBased only on last follow-up; n=106 & 76 for CT and 87 & 95 for LT
