The relationship between an objective measure of glycaemic control (glycated haemoglobin (HbA1)) and personality variables was examined in two separate groups of adult Type 1 (insulin-dependent) diabetic patients. Study 1 included 121 patients, all of whom also had subjective self-reporting of treatment compliance assessed, while the first 57 patients had individual differences in intelligence, major dimensions of personality and forgetfulness documented. Study 2 examined 303 patients, all of whom had their major dimensions of personality assessed using a shortened and updated version of the original personality questionnaire. Demographic indices (age, onset-age, duration of diabetes) were assessed in both groups. No significant correlation was found between HbA1 and self-report compliance suggesting that self-reporting may be invalid as a measure of glycaemic control. In study 1 personality and intelligence variables did not correlate significantly with HbA1 values. Older patients with shorter duration of diabetes had significantly better glycaemic control (p < 0.05). A significant correlation was observed between HbA1 concentration and onset-age of diabetes (p < 0.001); the patients who had developed diabetes later in life were achieving better control of their blood glucose. In the larger number of subjects in study 2 no significant correlations were evident between HbA1 and personality variables. It is concluded that the predictors of glycaemic control indexed by HbA1 may be distinct from predictors of self-report compliance and that the latter have limited or no value in providing an assessment of quality of glycaemic control. There is no evidence of an effect of personality on glycaemic control as measured by HbA1.
在两组独立的成年1型（胰岛素依赖型）糖尿病患者中，研究了血糖控制的客观指标（糖化血红蛋白（HbA1））与人格变量之间的关系。研究1纳入了121名患者，所有患者均接受了治疗依从性的主观自我报告评估，同时记录了前57名患者在智力、人格主要维度和健忘方面的个体差异。研究2对303名患者进行了检查，所有患者均使用原始人格问卷的简化更新版本对人格主要维度进行了评估。两组均评估了人口统计学指标（年龄、发病年龄、糖尿病病程）。未发现HbA1与自我报告依从性之间存在显著相关性，这表明自我报告作为血糖控制的一种测量方法可能无效。在研究1中，人格和智力变量与HbA1值无显著相关性。糖尿病病程较短的老年患者血糖控制明显更好（p < 0.05）。观察到HbA1浓度与糖尿病发病年龄之间存在显著相关性（p < 0.001）；在生命后期患糖尿病的患者血糖控制更好。在研究2中更多的受试者中，HbA1与人格变量之间没有明显的显著相关性。得出的结论是，由HbA1索引的血糖控制预测因素可能与自我报告依从性的预测因素不同，并且后者在评估血糖控制质量方面价值有限或没有价值。没有证据表明人格对以HbA1衡量的血糖控制有影响。
