Anxiety disorders are some of the most prevalent psychiatric disorders, have early onset, are chronic and can cause functional impairment. It is, therefore, crucial to establish an accurate diagnosis for treatment and research purposes.
To test the validity and reliability of the W.H.O. Schedules for Clinical Assessment in Neuropsychiatry (SCAN Thai Version): Anxiety Disorders Section.
The linguistic clarity of the psychiatric schedules for Thais was tested by psychiatrists from the country's four regions. The psychiatrists were competent in the use of the schedules and their underlying objectives. Then between October 2004 and August 2005, Reliability of SCAN: anxiety disorder section was tested among 30 participants, including patients with anxiety disorders and normal volunteers.
Based on reactions from Thais and consultations from competent psychiatrists, content validity was established. The duration of interviews for anxiety disorders section averaged 45.1 min (SD = 13.5). The reliability determined by Cohen's kappa coefficient for the 83 items that related to anxiety disorders in the SCAN were in Section 3, 4, 5. This overall inter-rater reliability was 0.79 (SD = 0.22), which were in substantial level of agreement. The overall intra-rater reliability was rated by the same psychiatrist 2 weeks apart. The result was 0.84 (SD = 0.21), which was near perfect agreement. There were three items (3.6%) of fair agreement and five items (6%) of moderate agreement that were caused from discrepancy of item definitions and the subjectivity of raters.
The Anxiety Disorders Sections of the WHO Schedules for Clinical Assessment in Neuropsychiatry (SCAN Thai Version) were an effective tool for assessing symptoms of anxiety disorders among Thais.
焦虑症是最常见的精神疾病之一，起病早，病程慢性，可导致功能障碍。因此，为了治疗和研究目的，准确诊断至关重要。
检验世界卫生组织神经精神病学临床评估日程表（泰国版）：焦虑症部分的有效性和可靠性。
泰国四个地区的精神科医生对泰国语精神科日程表的语言清晰度进行了测试。这些精神科医生能够熟练使用日程表及其潜在目标。然后在2004年10月至2005年8月期间，对30名参与者（包括焦虑症患者和正常志愿者）进行了SCAN：焦虑症部分的可靠性测试。
根据泰国人的反应和专业精神科医生的咨询，确定了内容效度。焦虑症部分的访谈时长平均为45.1分钟（标准差 = 13.5）。通过科恩kappa系数确定的与SCAN中焦虑症相关的83个条目的可靠性在第3、4、5节。总体评分者间信度为0.79（标准差 = 0.22），处于高度一致水平。总体评分者内信度由同一位精神科医生在相隔2周时进行评定。结果为0.84（标准差 = 0.21），接近完美一致。由于条目定义的差异和评分者的主观性，有3个条目（3.6%）一致性一般，5个条目（6%）一致性中等。
世界卫生组织神经精神病学临床评估日程表（泰国版）的焦虑症部分是评估泰国人焦虑症症状的有效工具。
