Supplementary Material for: Care Needs Profiles and Their Association with Caregiver Strain among Community-Dwelling Older Adults with Cognitive Impairment

<b><i>Introduction:</i></b> This study examined distinct profiles of met and unmet care needs among community-dwelling older adults with cognitive impairment and their association with caregiver strain. <b><i>Methods:</i></b> Latent class analysis and multivariable regression were applied to data from 266 caregivers of older Singaporeans, aged 60 years and above, with cognitive impairment. Care needs were evaluated by caregivers using the Camberwell Assessment of Need for the Elderly. Caregiver strain was measured by the Zarit Burden Interview. <b><i>Results:</i></b> Four need profiles were identified: (1) no need (38% of caregivers), (2) met social and memory needs (29%), (3) no social and met memory needs (17%), and (4) unmet social and memory needs (16%). The unmet social and memory needs profile was associated with a higher level of caregiver strain, compared to the no need profile. <b><i>Discussion:</i></b> A person-centered approach captured heterogeneity in the care needs of community-dwelling older adults with cognitive impairment. Policymakers should develop tailored interventions based on need profiles that may help reduce caregiver strain.

<b><i>引言：</i></b> 本研究考察了认知受损社区居住老年人的已满足与未满足照护需求的不同分型，并探讨其与照料者负担的关联。
<b><i>方法：</i></b> 本研究采用潜类别分析（Latent Class Analysis）与多变量回归模型，对266名照料60岁及以上认知受损新加坡老年人的照料者所提供的数据进行分析。照护需求由照料者通过《老年康伯韦尔需求评估量表》（Camberwell Assessment of Need for the Elderly）进行评估，照料者负担则通过《扎里斯负担访谈量表》（Zarit Burden Interview）进行量化。
<b><i>结果：</i></b> 本研究共识别出四类照护需求分型：（1）无需求型（占照料者总数的38%）；（2）社交与记忆需求均已获得满足型（29%）；（3）无社交需求但记忆需求已获得满足型（17%）；（4）社交与记忆需求均未获得满足型（16%）。相较于无需求型，社交与记忆需求均未获得满足的分型对应更高的照料者负担水平。
<b><i>讨论：</i></b> 以个体为中心的研究方法揭示了认知受损社区居住老年人照护需求的异质性。政策制定者应基于不同的需求分型制定个性化干预方案，以助力降低照料者负担。
