Stringent long-term control of blood glucose concentration in patients with insulin-dependent diabetes mellitus (IDDM) can decrease albuminuria, presumably forestalling development of renal insufficiency. Personality characteristics may influence a diabetic patient's ability and willingness to follow a prescribed regimen to achieve glycemic control. This study investigated the relationship of 2 personality factors to renal deterioration time (from initiation of insulin therapy to renal failure) in 85 patients with IDDM and end-stage renal disease. Persons moderate in the personality trait of neuroticism and high in conscientiousness had renal deterioration times that were 12 years longer than persons with either high or low neuroticism and low conscientiousness, presumably because of better self-care. The implications of this study's findings are discussed.
