This study aims to report on the development and psychometric properties of the Portuguese-language Abe's BPSD score (ABS) to screen for neuropsychiatric symptoms (NPS).
ISPOR and COSMIN recommendations were followed to translate and culturally adapt the ABS. A validation study was conducted to assess the psychometric properties of the newly-translated instrument. Outpatients attending a psychogeriatric consultation were included by consecutive referrals and were assessed with the ABS, the Neuropsychiatric Inventory (NPI) and NPI Caregiver Distress scale (NPI-D), and the Mini-Mental State Examination (MMSE). The ABS reliability (internal consistency, item-total correlations, inter-rater and test-retest reliability), validity (concurrent and convergent), feasibility and diagnostic accuracy were examined.
Overall, 107 participants were included. The ABS Cronbach alpha was 0.672, and item-total correlations ranged from -0.056 to 0.546. Strong inter-rater (ICC 0.997; 95%CI: 0.995-0.999) and test-retest reliability (ICC 0.976; 95%CI: 0.958-0.986) were found. Concurrent validity with NPI was high (r = 0.847, < .001), and correlations with MMSE and NPI-D were also significant. An exploratory threshold score ≥2 is proposed to identify clinically relevant NPS.
Data provide satisfactory proof of ABS psychometric characteristics. Nevertheless, some items exhibited less optimal properties.
The newly-translated instrument proved to be relevant, valid and easy to use in a real geriatric clinical setting.
本研究旨在报告葡萄牙语 Abe 的 BPSD 评分（ABS）的开发和心理测量学特性，以筛查神经精神症状（NPS）。
遵循 ISPOR 和 COSMIN 建议对 ABS 进行翻译和文化适应性调整。进行了一项验证研究，以评估新翻译工具的心理测量特性。通过连续转介，将参加心理老年科咨询的门诊患者纳入研究，并使用 ABS、神经精神疾病问卷（NPI）和 NPI 照顾者困扰量表（NPI-D）以及简易精神状态检查（MMSE）对患者进行评估。评估了 ABS 的可靠性（内部一致性、项目总分相关性、评分者间信度和重测信度）、效度（同时和收敛效度）、可行性和诊断准确性。
共有 107 名患者参与了本研究。ABS 的 Cronbach alpha 系数为 0.672，项目总分相关性范围为-0.056 至 0.546。评分者间信度（ICC 0.997；95%CI：0.995-0.999）和重测信度（ICC 0.976；95%CI：0.958-0.986）均很强。与 NPI 的同时效度较高（r=0.847，<0.001），与 MMSE 和 NPI-D 的相关性也有统计学意义。提出一个探索性的临界值≥2 以识别临床上相关的 NPS。
数据提供了 ABS 心理测量特性的令人满意的证据。尽管如此，一些项目的表现并不理想。
新翻译的工具在真实的老年临床环境中被证明是相关的、有效的和易于使用的。
