To identify the validity evidence based on the content and response processes of the Rastreamento de Alterações Vocais em Idosos (RAVI; "Screening for Voice Disorders in Older Adults"), an epidemiologic screening for voice disorders in older adults.
This is a prospective, nonrandomized, cross-sectional, validation study.
Criteria for defining the domains and elaborating the questions were established to confirm the validity evidence based on the content. A multidisciplinary committee of 19 experts evaluated the questions, and the relevance and representation of the domains were analyzed using the Content Validity Index for Items (CVI-I) and the Content Validity Index (CVI), respectively. For validity evidence based on the response processes, 40 individuals of both sexes, aged ≥60 years, were stratified by demographic and socioeconomic condition. They responded to the RAVI, made suggestions, and their verbal and nonverbal reactions were observed.
The first version of the RAVI consisted of 20 questions related to sensations and perceptions associated with the voice. Although the CVI value of 0.80 was satisfactory, the CVI-I and the suggestions of the expert committee indicated that the scale needed to be reformulated. Consultation with older adults indicated a need for further adjustment. The preliminary version of the RAVI consisted of 16 questions.
The two aspects of validity evidence described in the present study were essential for adapting the questions to better fit the construct of the questionnaire. Other aspects of validity evidence and reliability analysis will be described in part II of this study.
基于老年人嗓音变化追踪筛查（RAVI；“老年人嗓音障碍筛查”）的内容和应答过程，确定其效度证据，RAVI是一项针对老年人嗓音障碍的流行病学筛查。
这是一项前瞻性、非随机、横断面的效度验证研究。
确立了定义各领域及拟定问题的标准以确认基于内容的效度证据。由19名专家组成的多学科委员会对问题进行评估，并分别使用条目内容效度指数（CVI-I）和内容效度指数（CVI）分析各领域的相关性和代表性。为了获取基于应答过程的效度证据对40名年龄≥60岁的男女个体按人口统计学和社会经济状况进行分层。他们对RAVI进行应答、提出建议，并观察其言语和非言语反应
RAVI的第一版包含20个与嗓音相关的感觉和感知问题。尽管CVI值为0.80是令人满意的，但CVI-I和专家委员会的建议表明该量表需要重新制定与老年人的咨询表明需要进一步调整。RAVI预试版包含16个问题。
本研究中描述的效度证据的两个方面对于调整问题以更好地符合问卷结构至关重要。效度证据的其他方面和信度分析将在本研究的第二部分进行描述。
