RESUMEN
Objective:To investigate the effects of self-help mindfulness-based stress reduction (MBSR) training on illness uncertainty andsleep quality in patients with atrial fibrillation (AF) after radiofrequency ablation. To provide the basis for improving the quality of life of these patients.Methods:This was a randam controlled Test. A convenient sampling method was used to select 90 patients with atrial fibrillation who underwent radiofrequency ablation in the First Peoples Hospital of Changzhou from January 2021 to December 2021. According to the random number table method. They were divided into the experimental group and the control group, with 45 cases in each group. The control group received routine nursing, and the observation group received home-based self-help MBSR training based on the routine nursing. Five Facet Mindfulness Questionnaire (FFMQ), Mishel Uncertainty in Illness Scale and the Pittsburgh Sleep Quality Index Scale (PSQI) were used to evaluate the scores of each scale before intervention, 8 weeks and 3 months after intervention.Results:A total of 42 cases were completed in the experimental group and 41 cases in the control group. Repeated measurement analysis of variance showed that there were interaction effect ( F interaction = 90.98, 46.27, 39.61, all P<0.01), time effect ( F time = 298.67, 179.06, 76.32, all P<0.01) and inter-group effect ( F intergroup = 19.88, 4.07, 18.70, all P<0.05) on mindfulness score, disease uncertainty score, total score of sleep quality and scores of all dimensionsin between the two groups. Simple effect analysis showed that scores of all scales in experimental groups were significantly better than those in control group after the intervention ( F values were 11.75 to 66.49, all P<0.01). Conclusion:Self-help MBSR training can improve the level of mindfulness, reduce the feeling of uncertainty and improve the quality of sleep in patients with atrial fibrillation after radiofrequency ablation.
