The degree of burden related to the demands of daily care provided to a dependent older adult is important to evaluate due to the negative influence exerted on caregivers' physical and psychological health.
To analyze the validity of the 12-item version of the Zarit Burden Interview administered to older caregivers of community-dwelling older dependent individuals and suggest a cut-off score based on quartiles.
Three hundred and forty-one older caregivers (mean age: 69.6±7.1 years; 76.8% women) registered with primary healthcare centers were evaluated using the ZBI-12. Additional evaluations addressed stress (Perceived Stress Scale [PSS]), depressive symptoms (Geriatric Depression Scale [GDS]) in the older caregivers and the degree of dependence of the older care recipients (Lawton and Brody [L&B]).
Cronbach's alpha demonstrated very good internal consistency (α=0.81). Correlations were found between all ZBI-12 items and overall score on the PSS (r=0.53; p<0.01). GDS (r=0.43; p<0.01) and L&B (r= -0.23; p<0.01) scale scores. The PSS demonstrated the strongest correlation with ZBI-12 score and proved to be the standard reference. Based on caregivers with a higher degree of stress considering the PSS score quartiles, a cut-off score of 13 points on the ZBI-12 is suggested for screening burden in community-dwelling older caregivers, but should not be assumed as normative data.
The ZBI-12 can be considered valid for evaluation of burden in clinical practice and research as a fast, efficient option for screening burden among older caregivers of community-dwelling older adults.
由于对日常照料依赖型老年人的需求所带来的负担程度会对照料者的身心健康产生负面影响，因此对其进行评估很重要。
分析对社区居住的老年依赖个体的老年照料者进行的12项版Zarit照料负担访谈的有效性，并根据四分位数建议一个临界值。
使用ZBI - 12对在初级医疗保健中心登记的341名老年照料者（平均年龄：69.6±7.1岁；76.8%为女性）进行评估。另外还评估了照料者的压力（感知压力量表[PSS]）、抑郁症状（老年抑郁量表[GDS]）以及老年受照料者的依赖程度（劳顿和布罗迪[L&B]量表）。
克朗巴哈系数显示出非常好的内部一致性（α = 0.81）。发现ZBI - 12所有项目与PSS总分之间存在相关性（r = 0.53；p < 0.01），与GDS量表得分（r = 0.43；p < 0.01）以及L&B量表得分（r = - 0.23；p < 0.01）也存在相关性。PSS与ZBI - 12得分的相关性最强，被证明是标准参考。根据PSS得分四分位数中压力程度较高的照料者情况，建议ZBI - 12的临界值为13分，用于筛查社区居住老年照料者的负担，但不应将其视为规范数据。
ZBI - 12可被认为在临床实践和研究中用于评估负担是有效的，是筛查社区居住老年人的老年照料者负担的一种快速、有效的选择。
