The Camberwell Assessment of Need for the Elderly (CANE) is widely used for multidimensional evaluation of older people with mental health problems. The aim of this study was to evaluate reliability and validity of a Portuguese version of CANE.
A cross-sectional multicenter study was designed using a convenience sample of elderly mental health services' users. CANE was compared with EASYCare, GHQ12, MMSE, Barthel Index and GDS15 to assess criterion and construct validity. Inter-rater and test-retest reliability were also assessed.
79 patients (76% female), with mean age of 74 (+/- 6.6) years were included. Most patients lived at home with a family caregiver, generally female. Only 32% had no carer. Dementia was the commonest psychiatric diagnosis (61%) and somatic comorbidity was very prevalent (85%). Kappa values (kappa) for inter-rater item reliability ranged from 0.72 to 1.00 (mean values: 0.96 patient, 0.93 carer, 0.90 staff). The intraclass correlation coefficient (ICC) for total scores ranged from 0.95 to 0.98.For test-retest item reliability, the mean kappa value was: 0.80 patient, 0.77 carer, 0.81 staff. ICC for total scores ranged from 0.82 to 0.92. Given the absence of a gold standard, criterion validity was assessed by comparing CANE with EASYCare (rs 0.460; p < or = 0.01), GDS (rs 0.615; p < or = 0.01), GHQ (rs 0.581; p < or = 0.01) and Barthel Index (rs-0.435; p < or = 0.01). Overall, inter-item and item-total correlations for CANE and item comparison with other measures indicated reasonable construct validity.
The psychometric proprieties of CANE seem to be consistently good, in accordance with other studies. Robust results on ecological, face, content, criterion and construct validity, as well as good reliability, were achieved. This version is a promising tool for research and practical use in Portuguese old age settings.
坎伯韦尔老年需求评估量表（CANE）被广泛用于对有心理健康问题的老年人进行多维度评估。本研究的目的是评估葡萄牙语版CANE的信度和效度。
采用横断面多中心研究，以老年心理健康服务使用者的便利样本为研究对象。将CANE与简易护理评估量表（EASYCare）、一般健康问卷12项（GHQ12）、简易精神状态检查表（MMSE）、巴氏指数和老年抑郁量表15项（GDS15）进行比较，以评估效标效度和结构效度。同时评估了评分者间信度和重测信度。
纳入79例患者（76%为女性），平均年龄74（±6.6）岁。大多数患者与家庭照顾者同住，照顾者一般为女性。只有32%的患者没有照顾者。痴呆是最常见的精神科诊断（61%），躯体共病非常普遍（85%）。评分者间条目信度的kappa值范围为0.72至1.00（平均值：患者为0.96，照顾者为0.93，工作人员为0.90）。总分的组内相关系数（ICC）范围为0.95至0.98。重测条目信度的平均kappa值为：患者0.80，照顾者0.77，工作人员0.81。总分的ICC范围为0.82至0.92。由于缺乏金标准，通过将CANE与EASYCare（rs 0.460；p≤0.01）、GDS（rs 0.615；p≤0.01）、GHQ（rs 0.581；p≤0.01）和巴氏指数（rs -0.435；p≤0.01）进行比较来评估效标效度。总体而言，CANE的条目间和条目与总分的相关性以及与其他测量方法的条目比较表明其具有合理的结构效度。
与其他研究一致，CANE的心理测量学特性似乎一直良好。在生态效度、表面效度、内容效度、效标效度和结构效度方面取得了可靠的结果，信度也良好。这个版本是葡萄牙老年环境中研究和实际应用的一个有前景的工具。
