Impact of Adapted Mindfulness Training Integrating Interoception on Diabetic Patients With Impaired Awareness of Hypoglycemia: A Randomized Controlled Trial
Impact of Adapted Mindfulness Training Integrating Interoception on Diabetic Patients With Impaired Awareness of Hypoglycemia: A Randomized Controlled Trial
The purpose of this randomized controlled trial is to evaluate the effectiveness of an 8-week interoception-integrated adapted mindfulness training program for patients with type 1 or type 2 diabetes who experience impaired awareness of hypoglycemia (IAH). The study aims to determine whether this mindfulness intervention, which includes techniques such as body scanning and mindful eating, can help patients better recognize early physiological signals of low blood sugar compared to routine care. Researchers will measure changes in participants' interoceptive awareness and the severity of their IAH over a 3-month follow-up period. The ultimate goal is to provide a practical psychological approach to improve symptom perception and reduce the risk of severe hypoglycemic events in diabetic patients.
Diabetic patients are prone to hypoglycemia during insulin therapy, and repeated episodes can lead to impaired awareness of hypoglycemia (IAH), significantly increasing the incidence of severe hypoglycemia and adverse health outcomes. Recent studies indicate that altered interoceptive awareness is closely associated with an increased risk of IAH, and mindfulness interventions can effectively enhance an individual's interoceptive awareness. This study aims to explore the effects of an interoception-integrated adapted mindfulness training program on interoceptive awareness and impaired awareness of hypoglycemia in diabetic patients. This study is a two-arm, parallel-group randomized controlled trial. It plans to recruit 100 type 1 or type 2 diabetic patients with IAH who meet the eligibility criteria (e.g., Gold score ≥ 4 and Clarke score ≥ 4) from two community health centers in Yangzhou. Participants will be randomly assigned in a 1:1 ratio to either the intervention group (n=50) or the control group (n=50). The control group will receive routine treatment, examinations, nursing care, and health education. On this basis, the intervention group will receive an 8-week interoception-integrated adapted mindfulness training program, conducted once a week (1-1.5 hours per session). Based on Mindfulness-Based Stress Reduction (MBSR), the program utilizes core techniques such as body scanning, mindful eating, and mindful walking to reinforce patients' perception and awareness of early physiological signals of hypoglycemia, supplemented by daily home practices. Primary outcomes are the patients' interoceptive awareness (assessed by the MAIA-2 scale) and the severity of impaired awareness of hypoglycemia (evaluated by the Clarke and Gold questionnaires). Secondary outcomes include mindfulness levels (FFMQ) and negative cognitive processing bias (NCPBQ). Data collection time points are set at pre-intervention (T0), immediately post-intervention (T1), 1 month post-intervention (T2), and 3 months post-intervention (T3). Statistical analyses will employ descriptive statistics, univariate analysis, and Generalized Estimating Equations (GEE) to evaluate the intervention effects. This study is expected to provide a practical psychological intervention to improve symptom perception in diabetic patients with IAH, thereby reducing the incidence of severe hypoglycemia and improving clinical outcomes.
