Abstract
Self-care is important for type 2 diabetes mellitus (T2DM) patients’ disease prognosis, but there is a common phenomenon of self-regulation failure in T2DMs. In order to figure this problem out, the current study explored the interaction between self-regulation resource depletion and diabetes self-care based on the limited resource model of self-regulation. 104 patients were surveyed using the Self-Regulatory Fatigue Scale (SRF-S) and the Diabetes Self-care Scale (DSCS) in study 1. Study 2 recruited 30 T2DM patients and 30 healthy controls, and used a sequential-task paradigm to test the effect of self-regulation resource depletion on them. Participants in study 3 were 60 T2DM patients under different levels of self-regulation resource depletion manipulation, and their self-regulation performance was recorded and compared. Study 1 indicated that the correlation between self-regulation resource depletion and exercise and diet was significant and negative, suggesting that patients with greater self-regulation resource depletion performed poorly in exercise and diet. In Study 2, T2DM patients exhibited a poorer performance on the Spatial Incompatibility Task than the participants in the control group, suggesting that their self-regulation resource was insufficient. Study 3 indicated that there was no difference in Spatial Incompatibility Task performance, reaction time or error number among patients who were requested to complete a dietary record for one week and patients who were only requested to record eating times. This research demonstrated that low levels of diabetes self-care execution was associated with patients’ deficiency in self-regulatory resource, and self-care as a series of goal-directed behaviors consumed patients’ self-regulatory resources before these behaviors became a habit.
Highlights
Type 2 diabetes mellitus (T2DM) is a long-term metabolic disorder that is characterized by high blood sugar, insulin resistance, and a relative lack of insulin
A “sequential-task” paradigm was used to measure the self-regulation resource depletion effect, and we proposed that compared with healthy group, participants with T2DM would perform more poorly on the second self
Consistent with previous studies, our results indicated that self-care was suboptimal in diabetes mellitus patients in this study, with the exception of taking medicine
Summary
Type 2 diabetes mellitus (T2DM) is a long-term metabolic disorder that is characterized by high blood sugar, insulin resistance, and a relative lack of insulin. Hagger et al [15] observed that the capacity to regulate eating under self-regulation resource depletion conditions was reduced in individuals with high body mass indexes (BMI) who had frequently sought to reduce their food intake. This finding suggested that chronic self-regulation resource depletion impaired goal-directed diet behavior. A new T2DM patient must change his/her lifestyle in many areas (e.g., diet, exercise, smoking, and drinking) Will execution of these new behaviors induce depletion of the patient’s self-regulation resources? This study sought to examine the association between diabetes self-care and chronic self-regulation resource depletion
