Predictors of Self-Reported Medication Adherence (6-Day Recall)

Predictor	Univariate Spearman rho	Multiple Poisson Regression Model
Fewer Cues to Action (HBM)	−.35	β = −.32 (SE = .139), p = .011
Higher Barriers – Confusion (HBM)	−.28
Greater Self-Efficacy for Adherence (HBM, IMB)	+.33	β = .38 (SE = .16), p = .018
Greater Intention to Adhere (TPB)	+.32	β = .28 (SE = .11), p = .009
Higher Functional Ability (IMB)	+.21
Greater Motivation for Treatment (IMB, MM)	+.22
More Negative Overall Mood (MM)	−.21
More Anxiety (MM)	−.17
Greater Social Support (MM)	+.18

Note. Regression model results are after controlling for nonsignificant between-site differences. In the multiple regression model, 20% of the total variance in adherence was accounted for (pseudo R-square computed from log likelihood values of the final model compared to the null model). All significant univariate predictors were included in the multiple regression analysis, but only the significant multiple regression results are presented. D = demographic predictor, C = clinical predictor, HBM = variable from the Health Belief Model, TPB = variable from the Theory of Planned Behavior, IMB = variable from the Information-Motivation-Behavioral Skills model, MM = variable from the Motivational Model.
