Abstract

OBJECTIVE: To develop and test latent variables of the social determinants of health that influence diabetes self-care.

METHODS: 615 adults with type 2 diabetes were recruited from two adult primary care clinics in the southeastern United States. Confirmatory factor analyses (CFA) identified the latent factors underlying socioeconomic determinants, psychosocial determinants, and self-care (diet, exercise, foot care, glucose testing, and medication adherence). Structured equation modeling (SEM) investigated the relationship between determinants and self-care.

RESULTS: Latent variables were created for diabetes self-care, psychological distress, self-efficacy, social support and social status. The initial model (chi2(254) = 388.04, p < 0.001, RMSEA = 0.03, CFI = 0.98) showed that lower psychological distress (r = -0.13, p = 0.019), higher social support (r = 0.15, p = 0.008), and higher self-efficacy (r = 0.47, p < 0.001) were significantly related to diabetes self-care. Social status was not significantly related to self-care (r = 0.003, p = 0.952). In the trimmed model (chi2(189) = 211.40, p = 0.126, RMSEA = 0.01, CFI = 0.99) lower psychological distress (r = -0.13, p = 0.016), higher social support (r = 0.15, p = 0.007), and higher self-efficacy (r = 0.47, p < 0.001) remained significantly related to diabetes self-care.

CONCLUSION: Based on theoretical relationships, three latent factors that measure social determinants of health (psychological distress, social support and self-efficacy) are strongly associated with diabetes self-care.

PRACTICE IMPLICATIONS: This suggests that social determinants should be taken into account when developing patient self-care goals.
