A LONGITUDINAL STUDY IN PSYCHIATRIC EPIDEMIOLOGY

此应用程序涉及完成对 斯特林精神疾病流行病学纵向调查 县里的研究。在多个横截面的组合上绘制 调查和几次队列跟踪调查，主要目标是 提供有关以下方面的趋势、发生率和结果的信息 在普通人群中治疗和未治疗的精神障碍。 数据的主要内容包括：1)症状自报， 抑郁症和焦虑症的损害和持续时间通过 结构化问卷访谈；2)全科医生的报告 关于各种精神障碍的问题。这样的信息是 在1952年至1970年间收集了大约2848名成年居民的快速 加拿大东部农村环境的变化。 对于纵向研究，计算机程序被设计为 取代早期的“临床评估”程序。第一 实质性结果表明，抑郁症和焦虑症的流行 在1952年调查的样本中，基于自我报告的精神障碍占12.5% 在1970年的另一次抽样调查中为12.7%。这些东西的稳定性 流行率值得注意。 完成研究的具体目的涉及：1)效度 基于五个年度的结果的新的计算机方法 由临床精神科医生面对面进行的检查 122名成年人的子样本；2)基于以下情况的流行率的时间趋势估计 普通医生数据；3)基于不同类型疾病的发病率 关于队列分析；4)精神障碍结果，如康复， 复发、慢性病、残疾和死亡率；5)之间的关系 治疗和未治疗的疾病不仅依赖于护理的证据 由初级医生提供，也由精神科专科服务提供 如当地精神卫生中心的病例登记所示；6) 选定的风险因素之间的关系(器质性疾病、 经济地位、社会经历等)以及发病率、持续时间、 和不同类型精神障碍的结果；以及7)评估 一项预防方面的探索性试验。

This application concerns the completion of analysis and reporting of a longitudinal investigation of psychiatric epidemiology, the Stirling County Study. Drawing on a combination of multiple cross-sectional surveys and several cohort follow-up investigations, the main objective is to contribute information about trends, incidence, and outcome regarding treated and untreated psychiatric disorders in a general population. The main bodies of data consist in: 1) self report of symptoms, impairment, and duration of depression and anxiety disorders through structured questionnaire interviews; and 2) reports by general physicians about the full range of psychiatric disorders. Such information was gathered between 1952 and 1970 about 2848 adult residents of a rapidly changing rural environment in eastern Canada. For the longitudinal study, computer programs were designed that substitute for earlier "clinical evaluation" procedures. The first substantive results indicate that the prevalence of depression and anxiety disorders based on self report was 12.5% in a sample surveyed in 1952 and 12.7% in another sample surveyed in 1970. The stability of these prevalence rates is noteworthy. The specific aims involved in completing the study concern: 1) validity of the new computer methods based on using the results of five annual examinations carried out face-to-face by clinical psychiatrists for a subsample of 122 adults; 2) time trend estimates of prevalence based on general physician data; 3) incidence of different types of disorders based on cohort analysis; 4) psychiatric disorder outcomes such as recovery, relapses, chronicity, disability, and mortality; 5) relationships between treated and untreated disorders drawing not only on evidence of care provided by primary physicians but also by psychiatric specialty services as indicated in a case register of a local mental health center; 6) relationships among selected risk factors (organic medical disorders, economic position, social experiences, etc.) and the incidence, duration, and outcome of different types of psychiatric disorders; and 7) evaluation of an explorative trial in prevention.
