Data are presented as ; ^† values based on paired -tests for within-group changes from baseline to postintervention; ^Δthe effect of group was adjusted for patients’ age, gender, marital status, educational level, household income, employment status, diabetes duration, diabetes medication, and diagnosis of other chronic disease. Value interpretable in relation to the intervention group: a negative value indicates greater negative change, and a positive value indicates greater positive change in the intervention group compared with control subjects.
