The validity and reliability of the God Locus of Health Control (GLHC) scale were determined in a sample of 539 Mexican adults with type 2 diabetes mellitus. The validity analysis was based on the analysis of the GLHC scale’s items content and internal structure. The first procedure was conducted by six experts who evaluated the pertinence of the items adaptation. The second procedure consisted of a multiple-group confirmatory factor analysis by gender and age, aimed to evaluate the GLHC scale’s measurement invariance. Finally, reliability was estimated by means of coefficients ω and H. The confirmatory factor analysis demonstrated a six-item unifactorial structure, interpretable for the study population with measurement invariance by gender. Nevertheless, precautions should be taken when interpreting age-group comparisons. The magnitude of the construct reliability was high (>0....

Type 2 diabetes mellitus is a major public health problem with many elements, such as self-care and social support, that could be interacting with its evolution. Nevertheless, there is no evidence of association between these two elements. Thus, this study aims to determine the relationship between medical, nutritional and physical activity self-care, perceived social support and duration of the disease. A cross-sectional Study was conducted on 126 people with diabetes with a mean age of 55 (±10.4) years old. The Summary of Diabetes Self-Care Activities Scale and the Medical Outcomes Study (MOS) Social Support Survey were applied. Social support, specifically the instrumental one, may generate negative effects by limiting self-care behavior of a person. Based on these findings, it is possible to conclude that social support does not always turn out to be beneficial for people: having mo...
