SCALE TO IMPROVE MENTAL HEALTH DIAGNOSTIC ASSESSMENTS

拟议的项目与NIMH的研究主题情绪和心理状态评估有关。我们的目标是开发一个筛选问卷，帮助临床医生诊断最常见的DSM-IV轴I障碍似乎在门诊心理健康治疗的患者。精神病诊断筛查问卷（PDSQ）的构建要求：1）足够简单，患者可在就诊预约前完成; 2）基础足够广泛，可捕获常规临床实践中出现的更常见疾病; 3）易于快速手动评分，可立即获得信息; 4）直接基于DSM-IV诊断标准。第一阶段产生了一个121项问卷，与其他精神病理学的自我报告措施相比，具有较强的心理测量特性和有效性的证据。第一阶段还确定了在常规临床环境中使用PDSQ的可行性。最后，也是最重要的一步，在建设的PDSQ需要验证其性能对心理健康诊断目标标准-半结构化诊断面试-以确定灵敏度，特异性，阳性和阴性预测值为每个PDSQ分量表。拟定商业应用：目标市场包括心理健康专业人员，初级保健专业人员，健康维护组织，管理式护理公司和公司。该工具预计将提高诊断的准确性和面试效率与心理健康或初级保健设置的评估过程。在公司环境中，该工具预计将用于员工援助计划。

The proposed project is related to NIMH research topic Assessment of Emotional and Psychological States. The goal is to develop a screening questionnaire that assists clinicians in diagnosing the most common DSM-IV Axis I disorders seem in patients presenting for outpatient mental health treatment. The Psychiatric Diagnostic Screening Questionnaire (PDSQ) has been constructed to be 1) brief enough to be completed by patients prior to their intake appointment, 2) sufficiently broad-based to capture the more frequent disorders seem in routine clinical practice, 3) amenable to quick hand scoring for immediate availability of information, and 4) directly based on DSM-IV diagnostic criteria. Phase I resulted in a 121- item questionnaire with strong psychometric properties and evidence of validity when compared to other self-report measures of psychopathology. Phase I also established the feasibility of using the PDSQ in routine clinical settings. The final, and most important, step in the construction of the PDSQ entails validating its performance up against the mental health diagnostic goal standard-a semi-structured diagnostic interview - to determine sensitivity, specificity, positive and negative predictive values for each PDSQ subscale. PROPOSED COMMERCIAL APPLICATION: The target markets include mental health professionals, primary care professionals, health maintenance organizations, managed care companies, and corporations. The instrument is expected to improve diagnostic accuracy and interview efficiency with the evaluation process in mental health or primary care settings. In the corporate setting, the instrument is expected to be used in employee assistance programs.
