To determine the validity and reliability of the Thai version of the WHO Schedules for Clinical Assessment in Neuropsychiatry (SCAN) Version 2.1, Eating Disorders Section
The SCAN interview version 2.1 Eating Disorders Section (section 9) was translated into Thai. The content validity of the translation was verified by comparing the back-translation to the English original. Whenever inconsistencies were encountered, the Thai version was adapted so that it correctly conveyed the meaning of the original English version. The revised Thai version was then field-tested in four regions (Suanprung Psychiatric Hospital, Jitavejkhonkaen Hospital, Srithanya Hospital and Suansaranrom Psychiatric Hospital, each place comprised 20 volunteers) for comprehensibility of the relatively technical language. Re-edition of the Thai version was made in accordance with suggestions from the field trial. The reliability study was done between October 2005 and September 2008 in which 30 persons (4 males; 26 females) were recruited. Fifteen persons (1 males and 14 females) were eating disorders patients (4 anorexia nervosa and 11 bulimia nervosa patients) and the other 15 (3 males and 12 females) were normal. The number of years of formal education varied widely and occupations were diverse. Subjects were interviewed using SCAN eating disorders section by a psychiatrist competent in using the Thai version of SCAN. The interviews were recorded on video so that the material could be re-rated.
Regarding validity of WHO SCAN eating disorders section, based on the response from Thai subjects and consultations with competent psychiatrists, the content validity was established. Regarding the reliability study, the time taken to interview an eating disorder patient averaged 23.80 +/- 5.15 minutes (range, 18.35-34.26) versus 17.27 +/- 4.05 minutes (range, 9.07-22.37) for a normal subject. The mean of inter-rater reliability (kappa) of the eating disorder section was 0.73, standard error (SE) = 0.02, 95% confident interval (CI = 0.68-0.77). Seventy-eight point five percent of the items in the section had a substantial kappa. The mean of intra-rater reliabilities was 0.76, SE = 0.03, 95% CI = 0.70-0.82. Sixty-eight point four percent and 31.58% of the items had a substantial and almost perfect kappa respectively.
The Thai version of the Eating Disorders Sections of SCAN version 2.1 proved to be a valid and reliable tool for assessing eating disorders among Thai speakers.
确定世界卫生组织神经精神病学临床评估日程表(SCAN)第2.1版饮食失调章节泰语版的有效性和可靠性
将SCAN访谈第2.1版饮食失调章节(第9节)翻译成泰语。通过将回译与英文原文进行比较来验证翻译的内容效度。每当遇到不一致之处时,就对泰语版进行调整,以确保其正确传达英文原版的含义。然后,在四个地区(宣春精神病院、吉塔韦坚孔敬医院、斯里塔尼亚医院和宣萨拉隆精神病院,每个地方有20名志愿者)对修订后的泰语版进行实地测试,以检验相对专业的语言的可理解性。根据实地试验的建议对泰语版进行重新编辑。可靠性研究于2005年10月至2008年9月进行,招募了30人(4名男性;26名女性)。15人(1名男性和14名女性)为饮食失调患者(4名神经性厌食症患者和11名神经性贪食症患者),另外15人(3名男性和12名女性)为正常人。正规教育年限差异很大,职业也各不相同。由一位精通泰语版SCAN的精神科医生使用SCAN饮食失调章节对受试者进行访谈。访谈进行录像,以便对材料进行重新评分。
关于世界卫生组织SCAN饮食失调章节的有效性,根据泰国受试者的回答以及与专业精神科医生的咨询,确定了内容效度。关于可靠性研究,访谈一名饮食失调患者平均用时23.80±5.15分钟(范围为18.35 - 34.26分钟),而访谈一名正常受试者平均用时17.27±4.05分钟(范围为9.07 - 22.37分钟)。饮食失调章节的评分者间信度(kappa)均值为0.73,标准误(SE)=0.02,95%置信区间(CI = 0.68 - 0.77)。该章节78.5%的项目具有较高的kappa值。评分者内信度均值为0.76,SE = 0.03,95% CI = 0.70 - 0.82。该章节68.4%和31.58%的项目分别具有较高和几乎完美的kappa值。
SCAN第2.1版饮食失调章节的泰语版被证明是评估泰语使用者饮食失调的有效且可靠的工具。
