The present study examined the interactions between five dimensions of health locus of control beliefs and their relationships with medical regimen adherence in low-income individuals diagnosed with type 2 diabetes. One hundred and nine patients were administered an expanded Multidimensional Health Locus of Control (MHLC) scale. HbA1c was used as a biological indicator of medical regimen adherence. Multivariate regression analyses demonstrated that three interactions were significantly related to HbA1c. The present findings suggest that HLOC may be meaningfully related to medical outcomes. However, these relationships may not be captured through the examination of main effects and may be only found when interactions are considered.
