ASSESSMENT MODE AND VALIDITY OF SELF-REPORTS IN ADULTS

描述(改编自调查人员摘要)：自我报告是主要的 行为数据的来源。该组织和其他人的研究强调了 健康自评量表的变量效度和信度 坚持治疗等行为。敏感人群自我报告的研究 性行为和吸毒等信息表明，这种数据模式 收集可以提高自我报告的有效性。然而，没有研究表明 已确定数据收集模式在以下情况下如何影响自我报告 行为的客观衡量是可用的。这项研究的目标是 考察评估模式如何影响自我报告遵从性的有效性 接受哮喘治疗。自我报告坚持使用哮喘治疗将是 使用三种随机评估模式之一收集的数据：访谈、计算机 或者电话。成年患者将参加为期6个月的哮喘教育。 对他们吸入的药物进行电子监测以提供 客观的遵守措施。共有216名成年人将被随机分配到 这三种疗法。调查人员假设，自我报告将 在个性化程度最低的条件下具有最高的效度。他们会 还要检查面试模式如何影响其他行为和员工的自我报告 临床结果测量包括哮喘症状、哮喘管理和 生活质量。这项研究的结果将展示数据收集如何 方法影响治疗依从性的自我报告，并用于识别 在行为和临床研究环境中的最佳自我报告策略。

DESCRIPTION (adapted from investigator's abstract): Self-reports are a primary source of behavioral data. Studies by this group and others have highlighted the variable validity and reliability of self-report measures of health behaviors such as adherence with therapy. Research on self-reports of sensitive information, such as sexual behavior and drug use, suggests that mode of data collection may enhance validity of self-reports. However, no studies have determined how mode of data collection influences self-reports when an objective measure of the behavior is available. The goal of this study is to examine how assessment mode influences the validity of self-reported adherence with asthma therapy. Self-reported adherence with asthma therapy will be collected using one of three randomized assessment modes: interview, computer or telephone. Adult patients will be enrolled in a 6-month asthma education study where their inhaled medications are electronically monitored to provide an objective adherence measure. A total of 216 adults will be randomized to these three treatments. The investigators hypothesize that self-reports will have the highest validity under conditions of lowest personalization. They will also examine how interview mode influences self-reports of other behavioral and clinical outcome measures including asthma symptoms, asthma management and quality of life. Results from this study will demonstrate how data collection methods influence self-report of adherence with therapy and serve to identify optimal self-report strategies in behavioral and clinical research settings.
