Learning Objective 1: understand how worry, anxiety and depression affect psychosocial adaptation, glycemic control and quality of life in patients with type 2 diabetes mellitus

Learning Objective 2: know how we use the Roy´s Adaptation Model in a Mexican Adults with type 2 diabetes mellitus

Purpose: The purpose of this study was to test the theoretical relationships derived from the Roy Adaptation Model (RAM) to determine the influence of worry, anxiety and depression in glycemic control, psychosocial adaptation and quality of life in adults with T2DM.

Methods: The design selected was correlational design for test of a model of causal relationships. The sample (n = 250) was determined with 95% confidence and power test of 80% considering a coefficient of determination of 08.
Results: The final sample was comprised of 152 women and 98 men aged 30 to 50 years. The results showed that worry, anxiety and depression affect glycemic control(F(3249) = 2.18, p <.001); psychosocial adaptation (F (3249) = 55.65, p <.001) and the quality of life ( F (3249) = 48.74, p <.001) of adults with T2DM. However, the statistical model did not provide good criteria for accepting the causal relationships proposals (gl = 29; X2 = 187.84, p <.05, GFI = .89, AGFI = .74); the clinical and socio-demographic characteristics of adults with T2DM had no effect on states of worry, anxiety and depression in the general pattern. A new model introduced criteria of good adjustment in general (df = 2, X2 = 77, p = .679, GFI = .99, AGFI = 98. The adjustment of the model by gender, presented the following eligibility criteria (gl = 2, X2 = 1.43,p = .490, GFI = .99, AGFI = .94) in men and (df = 2, X2 = 25, p = .879, GFI = .99, AGFI = .99 ) in women.
Conclusion: the concerns about the influence of adults with depression and DMT2 adversely affected glycemic control, adaptation to the disease and quality of life of the participants in this study.
