Objectives:
To develop and validate a self-efficacy measure of diabetes self-management, the Lifestyle Self-Efficacy Scale for Latinos with Diabetes (LSESLD), designed for low-income, Spanish-speaking Latinos with diabetes.
Design:
Quantitative and qualitative methods.
Setting:
Community health centers in central and western Massachusetts.
Participants:
Low-income Latinos (N = 252) enrolled in a randomized diabetes self-management intervention trial.
Measures:
Construct validity, internal consistency, sensitivity to change over time.
Results:
The LSESLD demonstrated good internal consistency (Cronbach's alpha = .85), reasonable construct validity (moderate, significant associations between the LSESLD and validated measures of diabetes knowledge, dietary intake, physical activity, blood glucose self-monitoring, and HbA1c values), and sensitivity to intervention-related changes over time.
Conclusion:
The LSESLD is a reliable and valid research instrument assessing self-efficacy related to diabetes self-management among low-income, Spanish-speaking populations.
