ASSESSMENT MODE AND VALIDITY OF SELF-REPORTS IN ADULTS

描述（改编自研究者摘要）：自我报告是主要的 行为数据的来源。该小组和其他人的研究强调， 健康自评量表的变量效度和信度 行为，如坚持治疗。敏感性疾病的自我报告研究 性行为和吸毒等信息表明， 收集可以提高自我报告的有效性。然而，没有研究表明 确定数据收集模式如何影响自我报告， 对行为的客观衡量是可行的。本研究的目的是 检查评估模式如何影响自我报告依从性的有效性 哮喘治疗。自我报告的哮喘治疗依从性将 使用三种随机评估模式之一收集：访谈、计算机 或电话。成人患者将参加为期6个月的哮喘教育 研究中，他们的吸入药物被电子监控， 一个客观的坚持措施。共有216名成人将被随机分配至 这三种治疗方法。研究人员假设，自我报告将 在最低的个性化条件下具有最高的有效性。他们将 还研究了访谈模式如何影响其他行为和 临床结果测量，包括哮喘症状、哮喘管理和 生活质量本研究的结果将证明数据收集 方法影响自我报告的治疗依从性， 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.
