Although adherence to treatment regimes is clinically important in dia
betes mellitus, the best way to improve it is unclear. As a precursor
to evaluating the place of a brief intervention (motivational intervie
wing) in the treatment of diabetes, this study investigated the relati
on between motivation and glycemic control in 361 diabetic out-patient
s. Outcome measures were the Stages of Change Readiness and Treatment
Eagerness Scale (SOCRATES) and HbA(1C) level-a measure pf glycemic con
trol. The majority of patients (86.7%) could be allocated to a single
motivational stage, indicating that this concept is applicable in the
study of diabetes. There were significant associations between HbA(1C)
level and motivational stage, but not in the direction predicted. Tha
t is, patients at an earlier motivational stage had lower HbA(1C) leve
ls than those at later stages. The results suggest that feedback of Hb
A(1C) level may partly determine the patient's motivation to control t
heir diabetes, although the effect is quite weak. (C) 1997 Elsevier Sc
