Longitudinal mixed effects regression group × time outcomes across 1 month.

Coefficient/risk
ratio		 Standard
error		 95% CI Lower,
Upper		 P
Readiness to change (Total Score) 9.02 3.73 1.70 16.32 .02
Precontemplation 3.52 1.69 0.20 6.84 .04
Contemplation 1.71 1.05 −0.35 3.38 .10
Action 2.92 1.78 −0.57 6.41 .10
Maintenance 1.39 1.39 −1.34 4.12 .32

Suicidal ideation 1.36 0.24 0.95 1.93 .09

Note: All mixed effect regression models included gender in the analysis. Coefficients are utilized for all outcomes except for suicidal ideation, for which a risk ratio was used to report the Poisson regression model outcome. The coefficients and risk ratio reflect the group × time interaction effects for each outcome.
