Behavioral and Psychosocial Dynamics in Diabetes Management: A Path Analysis to Examine the Influence of...

Type 2 diabetes mellitus (T2DM) prevalence is rising globally. Arab immigrants with T2DM, one of the least studied ethnic minorities, have a higher diabetes prevalence and more prominent management-related challenges compared with mainstream host societies. Acculturation's impact on self-care activities and diabetes distress (DD) is understudied globally.

To examine how acculturation affects self-care practices and DD in first-generation Arab immigrants with T2DM and how health literacy, illness perceptions, and self-efficacy mediate these associations.

This multicenter cross-sectional study was conducted in Victoria, Australia. Eligible patients were invited while waiting for their appointments. The questionnaire included validated tools to assess DD, self-care activities, health literacy, self-efficacy, and acculturation. We tested mediation hypothesis using path analysis, with a maximum likelihood estimation to calculate total, direct, and indirect effects and bias-corrected accelerated 95% CI.

Overall, 382 Arab immigrants with T2DM participated, with an average age of 57.9 years (SD = 8.0). Half were males, most had low education, and were married. Participants lived in Australia for a mean of 19.1 years (SD = 8.3) and had diabetes for 7.1 years (SD =4.7). Higher acculturation was directly associated with decreased DD. Illness perceptions (p = .002) and self-efficacy (p = .001) mediated the association of acculturation with self-care activities, while health literacy did not. Additionally, self-efficacy fully mediated the relationship between acculturation and DD (p = .001).

This research provided valuable insights into the complex interplay between acculturation, diabetes management, and psychosocial factors. Interventions targeting self-efficacy and illness perceptions may improve self-care activities and reduce DD among Arab immigrants with T2DM.
