Personality in Type 1 Diabetes and the Impact of Personality Traits on the Effects of Introducing Diabetes Technology

The relationship between type 1 diabetes (T1D) and personality is complex. Personality traits may influence diabetes management, while living with diabetes may lead to stress and depression and potentially changes in personality traits over time.1–3 T1D is an autoimmune disease, causing insulin deficiency, requiring life-long insulin treatment and adherence to different treatment modalities is pivotal to optimal outcomes. Diabetes self-management is, from a clinical perspective, crucial to achieve the best outcomes in general and with diabetes technology. Recent technological advancements in diabetes self-management offer a promising outlook for enhancing treatment and patient-reported outcomes among persons with (T1D treated with multiple daily insulin injections).4 Advanced carbohydrate counting, defined as bolus calculation based on carbohydrate ratios and insulin sensitivity,5 has been shown to improve HbA1c and treatment satisfaction compared with experience-based insulin bolus dosing.6,7 Training in automated bolus calculation (ABC), may be even more efficient than manual bolus calculation.6,8 Intermittently scanned CGM (isCGM) provides glucose data on request and glucose alarms. Several studies have evaluated isCGM in terms of glycemic effectiveness and person-related outcomes.
