To develop a reliable and valid instrument to measure older adults' expectations regarding aging.
Using focus groups, cognitive interviews, and multitrait scaling analysis, we developed a 38-item survey to measure expectations regarding aging (ERA-38). The survey consisted of 10 scales, each representing a domain of expectations. We mailed the survey to 588 English-speaking patients aged 65 years and older cared for by University of California, Los Angeles-affiliated physicians.
Four hundred twenty-nine participants (73%) completed the survey. The mean age was 76 years; 54% were women. Most were White (76%). All scales other than Pain demonstrated good internal consistency reliability (alpha > or =.73) and item discrimination (> or =.80). Sixty-eight percent of respondents stated that all or most of the ERA-38 addressed things that were important. Construct validity was supported by correlations with age, activities of daily living, the Medical Outcomes Study Short Form-12 physical and mental component scores, and the Geriatric Depression Scale.
Considerable support for the reliability and construct validity of the ERA-38 was obtained in this field study of 429 older adults. This instrument should be useful to investigators interested in measuring expectations regarding aging among older adults.
开发一种可靠且有效的工具来测量老年人对衰老的期望。
通过焦点小组、认知访谈和多特质量表分析，我们编制了一份包含38个条目的调查问卷，以测量对衰老的期望（ERA - 38）。该调查问卷由10个分量表组成，每个分量表代表一个期望领域。我们将调查问卷邮寄给了588名由加州大学洛杉矶分校附属医生诊治的65岁及以上说英语的患者。
429名参与者（73%）完成了调查。平均年龄为76岁；54%为女性。大多数是白人（76%）。除疼痛分量表外，所有分量表均显示出良好的内部一致性信度（α≥0.73）和项目区分度（≥0.80）。68%的受访者表示ERA - 38的全部或大部分内容涉及重要事项。与年龄、日常生活活动、医学结局研究简表 - 12的生理和心理分量表得分以及老年抑郁量表的相关性支持了结构效度。
在这项对429名老年人的实地研究中，ERA - 38的信度和结构效度获得了相当多的支持。该工具对于有兴趣测量老年人对衰老期望的研究人员应该是有用的。
