RESUMEN
UNLABELLED: The information-motivation-behavioral skills (IMB) model of health behavior change informed the design of a brief, culturally tailored diabetes self-care intervention for Puerto Ricans with type 2 diabetes. Participants (n = 118) were recruited from an outpatient, primary care clinic at an urban hospital in the northeast United States. ANCOVA models evaluated intervention effects on food label reading, diet adherence, physical activity, and glycemic control (HbA1c). At follow-up, the intervention group was reading food labels and adhering to diet recommendations significantly more than the control group. Although the mean HbA1c values decreased in both groups ( INTERVENTION: 0.48% vs. CONTROL: 0.27% absolute decrease), only the intervention group showed a significant improvement from baseline to follow-up (p < .008), corroborating improvements in diabetes self-care behaviors. Findings support the use of the IMB model to culturally tailor diabetes interventions and to enhance patients' knowledge, motivation, and behavior skills needed for self-care.

Frameworks are needed to inform diabetes self-care programs for diverse populations. We tested the Information-Motivation-Behavioral Skills (IMB) model in a sample of Puerto Ricans with Type 2 diabetes (N = 118). Structural equation models evaluated model fit and interrelations between IMB constructs. For diet behavior, information and motivation related to behavioral skills ( r = 0.19, p < .05 and r = 0.39, p < .01, respectively); behavioral skills related to behavior (r = 0.42, p < .01 and r = 0.32, p < .05); and behavior related to glycemic control (r = -0.26, p < .05). For exercise, personal motivation related to behavioral skills (r = 0.53, p < .001), and behavioral skills related to behavior (r = 0.45, p < .001). The IMB model could inform interventions targeting these behaviors in diabetes.
