团体正念认知治疗改善痴呆患者护工心理状态及照料质量的随机对照试验OACHSSCD

Objective:To evaluate the effects of Group Mindfulness-Based Cognitive Therapy(MBCT)on psychological status and caregiving quality in dementia caregivers.Methods:Fifty caregivers of patients with de-mentia were randomly assigned to either MBCT(n=25)or supportive-counseling control group(n=25).Caregiv-ers were assessed at baseline and at weeks 4,8 and 12,using Generalized Anxiety Disorder-7(GAD-7),Patient Health Questionnaire-9 items(PHQ-9)and Neuropsychiatric Inventory Questionnaire-distress(NPI-Q-Distress).Caregiving quality was evaluated using NPI-Q Symptom Severity,pressure-ulcer incidence,and body-weight change in the patients they cared for.Result:Compared with controls,MBCT group showed significantly greater reductions in GAD-7and PHQ-9 at weeks 4,8 and 12 NPI-Q-distress reduced at weeks 8 and 12(Ps＜0.05).No significant differences were observed between groups in patients' pressure ulcer incidence or weight change(P＞0.05),but patients cared for by the MBCT group demonstrated lower NPI-Q-symptom severity scores at weeks 12(P＜0.05).Using ≥50％reduction as the threshold for clinical response,MBCT group showed significantly higher response rate on the GAD-7,PHQ-9,and NPI-Q distress scales(Ps＜0.05).Conclusion:Group MBCT effectivelyreduces negative emotions in dementia caregivers,and may indirectly alleviate dementia patient's psychiatric symptoms,highlighting its value for improving short-term care outcomes in dementia settings.
