The aim of this study was to investigate the feasibility and preliminary efficacy of a modified mindfulness-based stress reduction (MBSR) program and mindfulness-based cognitive therapy (MBCT) program for reducing the stress, depressive symptoms, and subjective burden of family caregivers of people with dementia (PWD).
A prospective, parallel-group, randomized controlled trial design was adopted. Fifty-seven participants were recruited from the community and randomized into either the modified MBSR group (n = 27) or modified MBCT group (n = 26), receiving seven face-to-face intervention sessions for more than 16 weeks. Various psychological outcomes were measured at baseline (T0), immediately after intervention (T1), and at the 3-month follow-up (T2).
Both interventions were found to be feasible in view of the high attendance (more than 70.0%) and low attrition (3.8%) rates. The mixed analysis of variance (ANOVA) results showed positive within-group effects on perceived stress (p = .030, Cohen's d = 0.54), depressive symptoms (p = .002, Cohen's d = 0.77), and subjective caregiver burden (p < .001, Cohen's d = 1.12) in both interventions across the time points, whereas the modified MBCT had a larger effect on stress reduction, compared with the modified MBSR (p = .019).
Both the modified MBSR and MBCT are acceptable to family caregivers of PWD. Their preliminary effects were improvements in stress, depressive symptoms, and subjective burden. The modified MBCT may be more suitable for caregivers of PWD than the MBSR. A future clinical trial is needed to confirm their effectiveness in improving the psychological well-being of caregivers of PWD.
本研究旨在探讨改良正念减压(MBSR)和正念认知疗法(MBCT)方案对减少痴呆症患者(PWD)家庭照顾者的压力、抑郁症状和主观负担的可行性和初步疗效。
采用前瞻性、平行组、随机对照试验设计。从社区招募了 57 名参与者,并将其随机分为改良 MBSR 组(n=27)或改良 MBCT 组(n=26),接受超过 16 周的 7 次面对面干预。在基线(T0)、干预后即刻(T1)和 3 个月随访(T2)时测量各种心理结果。
考虑到高出勤率(超过 70.0%)和低退出率(3.8%),两种干预措施均可行。混合方差分析(ANOVA)结果显示,两种干预措施在感知压力(p=0.030,Cohen's d=0.54)、抑郁症状(p=0.002,Cohen's d=0.77)和主观照顾者负担(p<0.001,Cohen's d=1.12)方面均有积极的组内效应。然而,与改良 MBSR 相比,改良 MBCT 对压力减轻的效果更大(p=0.019)。
改良 MBSR 和 MBCT 均被 PWD 的家庭照顾者接受。它们的初步效果是改善压力、抑郁症状和主观负担。与 MBSR 相比,改良 MBCT 可能更适合 PWD 的照顾者。需要进一步的临床试验来确认它们在改善 PWD 照顾者心理健康方面的有效性。
