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 (
0.48% vs.
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.
目的：本研究以健康行为改变的信息-动机-行为技能（IMB）模型为理论基础，为美国东北部一家城市医院的门诊初级护理诊所中患有 2 型糖尿病的波多黎各患者设计了一个简短的、具有文化适应性的糖尿病自我护理干预措施。
方法：参与者（n=118）从该诊所招募。采用协方差分析模型评估干预措施对食物标签阅读、饮食依从性、体力活动和血糖控制（HbA1c）的影响。随访时，干预组阅读食物标签和遵循饮食建议的比例显著高于对照组。尽管两组的平均 HbA1c 值均有所下降（干预组：0.48%；对照组：0.27%，绝对下降），但只有干预组从基线到随访时显示出显著改善（p<.008），这与糖尿病自我护理行为的改善相符。研究结果支持使用 IMB 模型对糖尿病干预措施进行文化适应性调整，并增强患者自我护理所需的知识、动机和行为技能。
