AB Objectives: To develop and psychometrically validate a questionnaire to identify barriers to self-care in this population on thebasis of the theory of planned behavior.Methods: The study was carried out in 15 primary healthcare centers belonging to the Public Health Care System in Andalusia(Spain). After content validity was confirmed, an initial pilot study was undertaken (n = 54) and the model was evaluated in 2samples of 205 subjects each to test its configural and metric invariance by confirmatory factor analysis. Internal consistency,test-retest reliability, criterion validity, and interpretability were carried out following COSMIN standards.Results: A 4-factor instrument (intention, subjective norms, perceived control, and attitudes) with 15 items was obtained witha good fit: goodness-of-fit index = 0.92, comparative fit index = 0.93, and root mean square error of approximation = 0.043(90% confidence interval 0.034-0.052). Cronbach a was 0.78, and test-retest reliability was adequate (intraclass correlationcoefficient 0.73; P , .0001). The instrument revealed an adequate criterion validity depending on the treatmentcomplexity and level of metabolic control. Thus, participants with poor self-care scores were more likely to suffer fromdiabetes-related complications (odds ratio 1.91; 95% confidence interval 1.15-3.1).Conclusions: A theory-driven instrument is suitable for its use with Spanish people with type 2 diabetes to assess their selfcareneeds and make tailored recommendations for lifestyle modifications on the basis of their behavioral determinants.
