项目摘要
DESCRIPTION (provided by applicant): Disturbed sleep represents a growing public health concern. Research shows that sleep problems are increasing and are linked to reduced productivity, increased traffic accidents, and increased medical illness. Sleep problems are also a modifiable risk factor for psychiatric illness. The development of inexpensive and validated measures of sleep disturbances is important for early identification, monitoring and treatment of sleep problems. Existing self-report measures of sleep disturbance have been criticized for not comprehensively measuring sleep problems and for not modeling the underlying dimensions of sleep disturbances. The long-term objective of this project is to validate the Iowa Sleep Disturbances Inventory (ISDI). The ISDI is a factor analytically derived instrument with 11 scales that comprehensively measure sleep distrubances (e.g., Insomnia, Nightmares, Movements). These scales are internally consistent and show good discriminant validity. This project proposes to continue the validation process of the ISDI by examining short-term retest stability, convergent and discriminant validity and criterion validity. Beyond this clinical goal, the project also has several theoretical objectives, including examining the differential relations between psychopathology and sleep disturbances and explicating the hierarchical structure of sleep disturbances. The Specific Aims are to (1) examine the short-term retest stability of the ISDI, (2) determine the structure of sleep disturbances by conducting exploratory factor analyses on the ISDI scales, (3) determine how specific sleep disturbances relate to depression, anxiety, substance use, and schizotypy/dissociation, (4) examinethe convergent and discriminant validity of the ISDI with a corresponding clinical interview based on the ISDI scales, (5) establish the criterion validity of the ISDI by correlating ISDI scales with psychological diagnoses from a structured clinical interview and (6) use confirmatory factor analysis to test the model of sleep disturbances obtained in the exploratoryfactor analyses. This project will be conducted with two independent studies. Study 1 will be conducted with a large student sample (N = 300) and will address Specific Aims 1-3. Study 2 will be conducted with a community sample (N = 150) and will address Specific Aims 4-6. The proposed project is necessary for the continuing validation of the ISDI. In addition, this project will result in the creation of a corresponding clinical interview that can be used by sleep researchers and clinicians to identify sleep disturbances. This project will significantly advancethe study of sleep and psychopathology by clarifying the structure of sleep disturbances and the relations between specific sleep disturbances and psychological disorders.
描述(由申请人提供):睡眠障碍是一个日益严重的公共卫生问题。研究表明,睡眠问题正在增加,并与生产力下降,交通事故增加和医疗疾病增加有关。睡眠问题也是精神疾病的一个可改变的风险因素。开发廉价且有效的睡眠障碍测量方法对于早期识别、监测和治疗睡眠问题非常重要。现有的自我报告的睡眠障碍的措施已被批评为没有全面测量睡眠问题,并没有模拟睡眠障碍的潜在维度。本项目的长期目标是验证爱荷华州睡眠障碍量表(ISDI)。ISDI是一种因素分析衍生工具,具有11个量表,可全面测量睡眠障碍(例如,inflation,nightweight,Movements).这些尺度是内部一致的,并表现出良好的判别效度。本项目建议通过检查短期重测稳定性、收敛和判别效度以及标准效度来继续ISDI的验证过程。除了这个临床目标,该项目还有几个理论目标,包括检查精神病理学和睡眠障碍之间的差异关系,并阐明睡眠障碍的层次结构。具体目的是(1)检查ISDI的短期重测稳定性,(2)通过对ISDI量表进行探索性因素分析来确定睡眠障碍的结构,(3)确定特定睡眠障碍与抑郁、焦虑、物质使用和精神分裂症/分离的关系,(4)以ISDI量表为基础,通过相应的临床访谈,检验ISDI量表的收敛效度和判别效度,(5)通过将ISDI量表与临床结构化访谈的心理诊断相关联,建立ISDI量表的效标效度;(6)采用验证性因素分析对探索性因素分析得到的睡眠障碍模型进行检验。该项目将进行两项独立的研究。研究1将采用大量学生样本(N = 300)进行,并将解决具体目标1-3。研究2将使用社区样本(N = 150)进行,并将解决具体目标4-6。拟议的项目对于持续验证ISDI是必要的。此外,该项目还将创建相应的临床访谈,可供睡眠研究人员和临床医生用于识别睡眠障碍。本项目通过阐明睡眠障碍的结构以及特定睡眠障碍与心理障碍之间的关系,将显著推进睡眠和精神病理学的研究。
