To determine the validity evidence based on the internal structure and relations to other variables and the reliability of an epidemiologic questionnaire for screening older adults with voice disorders.
This is a prospective, nonrandomized, cross-sectional, validation study.
To assess the validity evidence based on the internal structure, 160 older adults of both sexes, either community-dwelling or institutionalized, completed the "Rastreamento de Alterações Vocais em Idosos" (RAVI; "Screening for Voice Disorders in Older Adults"). The data were analyzed using item-total and interitem correlations, principal component analysis, confirmatory factor analysis, and differential item functioning. For validity evidence based on relations to other variables, measures of concurrent and discriminant validity were calculated according to the self-reported number of factors associated with voice disorders. Reliability was assessed using a test-retest procedure conducted with 121 older adults with the same characteristics as the previous sample. In this stage, the reproducibility, internal consistency, and measurement error of the instrument were analyzed.
The RAVI showed adequate validity evidence based on the internal structure and relations to other variables, as well as good reliability. This indicates that the results produced by the instrument are valid and reliable.
The RAVI is a self-reported outcome questionnaire that yields valid and reliable responses for epidemiologic detection of voice disorders in older adults and can be easily administered by any health care provider. Further ongoing studies will assess accuracy measures and cutoff values of the RAVI.
基于内部结构、与其他变量的关系确定有效性证据，并评估一份用于筛查老年嗓音障碍患者的流行病学调查问卷的可靠性。
这是一项前瞻性、非随机、横断面的验证性研究。
为评估基于内部结构的有效性证据，160名社区居住或机构养老的老年男女完成了“老年嗓音障碍筛查”（RAVI）问卷。数据采用项目-总分相关、项目间相关、主成分分析、验证性因子分析和项目功能差异分析。为评估基于与其他变量关系的有效性证据，根据自我报告的与嗓音障碍相关因素数量计算同时效度和区分效度指标。采用重测法对121名与前一样具有相同特征的老年人进行可靠性评估。在此阶段，分析了该工具的可重复性、内部一致性和测量误差。
RAVI基于内部结构和与其他变量的关系显示出充分的有效性证据，以及良好的可靠性。这表明该工具产生的结果是有效且可靠的。
RAVI是一份自我报告结局问卷，对于老年嗓音障碍的流行病学检测能产生有效且可靠的回答，并且任何医疗服务提供者均可轻松实施。正在进行的进一步研究将评估RAVI的准确性指标和临界值。
