Ninety six adults with type 1 or type 2 diabetes were assessed on measures of illness beliefs, mastery strivings, and emotion regulation processes in a cross sectional design to determine their predictive relationship to diabetes distress, self care behaviour, and blood sugar levels (the latter was measured at baseline and at 6 months follow up to allow cross sectional and longitudinal comparisons). When comparing illness beliefs with emotion regulation processes, illness beliefs (control; seriousness) and a specific emotion regulation process (rumination) predicted diabetes distress. Illness beliefs (particularly control and seriousness) partially mediated the association between emotional rumination and diabetes distress. When comparing mastery strivings with illness beliefs, diabetes distress was predicted by a particular mastery striving (perfectionism) and specific illness beliefs (control; seriousness). Illness beliefs (control and seriousness) mediated the association between specific mastery variables (Type A and rational coping) and diabetes distress. In a comparative evaluation of mastery strivings and illness beliefs as potential predictors of self care behaviours, rational coping (a mastery striving) predicted general diet in the final model. Perceived control partially mediated the effect of rational coping on general diet. None of the mastery striving variables or illness beliefs predicted exercise in the final model (rational coping, while predictive at step two, dissolved at step three). When comparing self care behaviours with psychophysiological variables in relation to blood sugar levels, none of the components of either grouping predicted HbA1c scores at baseline. However, at 6 months follow-up, one specific psychophysiological variable - emotional inhibition - predicted blood sugar levels. Conclusion: Illness beliefs possibly mediate the effects of more generic personality characteristics – mastery strivings and emotional regulation processes – on diabetes outcomes (emotional adjustment, self care behaviour). Moreover, an emotion regulation process (inhibition) directly mediated changes in blood sugar levels.
