Abstract

Background: The concept of oral frailty has gained scientific and clinical relevance in recent years, and early detection can facilitate timely intervention to manage its progression. The Oral Frailty Index-8 (OFI-8) was developed to assess community-dwelling older adults at risk for oral frailty.

Objective: This study aims to investigate the psychometric validity of the OFI-8 in the Portuguese population, named the Portuguese version of the OFI-8 (OFI-8-PT), which may serve as a reference for future studies related to longevity and oral function.

Methods: This study included 2 main phases, involving patients aged 60 years or older, Portuguese speakers, and those who consented to participate in the study. First, the researchers translated and cross-culturally adapted the original questionnaire to make it suitable for native Portuguese speakers. The translated tool was then assessed for psychometric validation, which consisted of test-retest reliability, internal consistency, construct validity, and sex invariance measurement.

Results: A total of 159 older adults participated in the baseline survey, with almost equal numbers of male (n=79, 49.7%) and female participants (n=80, 50.3%). The OFI-8-PT demonstrated good reliability (Cronbach α=0.95) and construct validity (goodness-of-fit index=0.96; comparative fit index=0.85; and root mean square error of approximation=0.05, 90% CI 0.00-0.09). The study found sex invariance, indicating that the OFI-8-PT is equally valid for male and female participants, and the tested-retest reliability of the OFI-8-PT was good, indicating consistent results over time.

Conclusions: The OFI-8-PT showed psychometric validity and good reliability to be used in the Portuguese population.

葡萄牙语版口腔虚弱指数-8:工具验证研究。
背景:近年来,口腔虚弱的概念在科学和临床上越来越重要,早期发现有助于及时干预,控制其发展。口腔虚弱指数-8(OFI-8)是为评估社区老年人口腔虚弱风险而开发的:本研究旨在调查 OFI-8 在葡萄牙人群中的心理测量有效性,并将其命名为葡萄牙语版 OFI-8(OFI-8-PT),作为未来有关长寿和口腔功能研究的参考:这项研究包括两个主要阶段,涉及 60 岁或以上、讲葡萄牙语和同意参与研究的患者。首先,研究人员对原始问卷进行了翻译和跨文化改编,使其适合以葡萄牙语为母语的人使用。然后,对翻译后的工具进行了心理测量学验证评估,包括重测可靠性、内部一致性、结构效度和性别不变性测量:共有 159 名老年人参加了基线调查,其中男性(79 人,占 49.7%)和女性(80 人,占 50.3%)人数几乎相等。OFI-8-PT 具有良好的可靠性(Cronbach α=0.95)和建构效度(拟合优度指数=0.96;比较拟合指数=0.85;近似均方根误差=0.05,90% CI 0.00-0.09)。研究发现,OFI-8-PT具有性别不变性,表明OFI-8-PT对男性和女性参与者同样有效,而且OFI-8-PT的重测信度良好,表明其结果在一段时间内保持一致:OFI-8-PT显示了心理测量的有效性和良好的可靠性,可用于葡萄牙人群。
