世界卫生组织（世卫组织）残疾评估量表II（世卫组织-DAS II）是一个通用的健康状况工具，牢固地建立在世卫组织的国际功能、残疾和健康分类（世卫组织-ICF）的基础上。因此，它评估了六个领域的功能：沟通，流动性，自我照顾，人际关系，生活活动和参与。域分数汇总为总分。由于WHO-DAS II包含与听力和沟通相关的问题，因此它具有良好的表面效度，可用作听力干预的结局指标。本研究的目的是确定的心理测量学特性的WHO-DAS II的成人发病性听力损失的个人样本，包括收敛效度，内部一致性和重测稳定性。通过检查WHO-DAS II（领域和总评分）与助听器福利简明概况（APHAB）和老年人助听器残疾（HHIE）（两种疾病特异性措施）以及退伍军人简表-36（SF-36V）（第二种通用措施）之间的相关性，建立了收敛效度。所有四项指标的数据均收集自380名未使用助听器的成人型听力损失老年人。聚合效度分析结果显示，WHODAS II沟通领域得分与APHAB和HHIE得分呈中度和显著相关。WHO-DAS Ⅱ人际、参与领域得分及总分与HHIE评分呈中度和显著相关。这些发现支持使用WHO-DAS II评估成人听力损失的活动限制和参与限制的有效性。多个WHO-DAS II领域评分和总分与SF-36 V评分也存在显著和中度显著相关。这些结果支持世卫组织DAS II作为通用健康状况工具的有效性。内部一致性可靠性的所有领域的分数是足够的，但人际领域。所有领域分数的重测稳定性是足够的。计算临界差值，用于WHO-DAS II的临床应用。从这些发现中，我们得出结论，WHO-DAS II沟通，参与和总分可用于检查成人听力损失对功能健康状况的影响。进一步研究WHO-DAS II作为助听器干预结果指标的效用是必要的。
The World Health Organization's (WHO) Disability Assessment Scale II (WHO-DAS II) is a generic health-status instrument firmly grounded in the WHO's International Classification of Functioning, Disability and Health (WHO-ICF). As such, it assesses functioning for six domains: communication, mobility, self-care, interpersonal, life activities, and participation. Domain scores aggregate to a total score. Because the WHO-DAS II contains questions relevant to hearing and communication, it has good face validity for use as an outcome measure for audiologic intervention. The purpose of the present study was to determine the psychometric properties of the WHO-DAS II on a sample of individuals with adult-onset hearing loss, including convergent validity, internal consistency, and test-retest stability. Convergent validity was established by examining correlations between the WHO-DAS II (domain and total scores) and the Abbreviated Profile of Hearing Aid Benefit (APHAB) and the Hearing Aid Handicap for the Elderly (HHIE), two disease-specific measures, as well as with the Short Form-36 for veterans (SF-36V), a second generic measure. Data on all four measures were collected from 380 older individuals with adult-onset hearing loss who were not hearing aid users. The results of the convergent validity analysis revealed that the WHODAS II communication domain score was moderately and significantly correlated with scores on the APHAB and the HHIE. WHO-DAS II interpersonal and participation domain scores and the total scores were also moderately and significantly correlated with HHIE scores. These findings support the validity of using the WHO-DAS II for assessing activity limitations and participation restrictions of adult-onset hearing loss. Several WHO-DAS II domain scores and the total score were also significantly and moderately-markedly correlated with scores from the SF-36V. These findings support the validity of the WHO-DAS II as a generic health-status instrument. Internal consistency reliability for all the domain scores was adequate for all but the interpersonal domain. Test-retest stability for all the domain scores was adequate. Critical difference values were calculated for use in clinical application of the WHO-DAS II. From these findings, we concluded that the WHO-DAS II communication, participation, and total scores can be used to examine the effects of adult-onset hearing loss on functional health status. Further work examining the utility of the WHO-DAS II as an outcome measure for hearing aid intervention is warranted.
