Purpose: Personality traits are an important factor in health behaviors. However, personality traits and self-care in T2DM in the Mexican population are not yet explored due to this; the purpose of this work was to explore the relationship of personality traits with self-care in Mexican adults with type 2 diabetes mellitus.
Patients and methods: A cross-sectional study was carried out in a sample of 197 T2DM patients from a primary care center in Oaxaca, Mexico. The Big Five Inventory and the Summary of Diabetes Self-care Activities (SDSCA) were the tools used. Correlation models and multiple linear regression models were used for the analysis.
Results: Most of the study participants were women (74.6%). The mean age was 53.1 years (SD = 8.4). The average years of schooling of the participants were 5.7 (SD = 4.3). The number of years lived with T2DM was 9.0 (SD = 6.5). The waist circumference was 96.3 (SD = 14.2), and the BMI was 27.5 kg/m2 (SD = 4.1). The traits of conscientiousness (r = 0.283) and openness (r = 0.259) were positively correlated with self-care activities, while neuroticism was inversely correlated (r = -0.144). In the multiple linear regression models, only the conscientiousness and openness traits were predictors of self-care; they explained 19% of the variance.
Conclusion: People with greater openness and conscientiousness were associated with greater compliance with self-care. Conversely, neuroticism was inversely associated with self-care in patients with T2DM.
