Multivariate, Multilevel Regression Model Showing Association of Clinician Use of Chronic Care Model Elements and 2 Measures of Process of Diabetes Care

Parameter	Parameter Estimate*	SE	P Value
PHQ-9 = 9-item Patient Health Questionnaire; CCM = Chronic Care Model.
* The parameter estimates indicate the strength of the association in each model. Each unit difference in clinician-reported frequency of CCM use (eg, from “rarely” to “occasionally”) is associated with a change in the dependent variable (behavioral care composite score or clinical care composite score) equal to the parameter estimate.
† Covariates included patient age, race/ethnicity, and severity of depressive symptoms (PHQ-9 score).
‡ Covariates included patient age and race/ethnicity.
