METHODS: An expert panel developed a self-administered questionnaire survey with three domains: (1) dentists\' knowledge on diagnosis, recording, and managing root caries; (2) information about their current general clinical routines; (3) their demographics. The original English [E] version was translated into three different languages (French [F], German [G], Italian [I]), and subsequently back-translated into English by independent dentists. For the validation, 82 dentists (20-22 for each of the translated versions) accepted to answer the questionnaire at two different time-points (with 1-week interval). The data was quality checked. Construct validity, internal reliability, and intra-class correlation (ICC) were assessed.
RESULTS: Seventy-seven dentists completed the questionnaire twice [E: 17; F: 19; G: 19; I: 22]. The mean ICC (standard deviation) was 0.98(0.03) for E, 0.90(0.12) for F, 0.98 (0.04) for G, and 0.98 (0.01) for I. Overall, the test-retest reliability was excellent (mean ICC (SD): 0.96 (0.08)). Furthermore, the questionnaire demonstrated good internal reliability (inter-observer reliability; Fleiss kappa: overall:0.27(fair); E:0.30 (fair); F: 0.33(fair); G: 0.33(fair); I: 0.89 (almost perfect)).
CONCLUSIONS: The questionnaire was validated and is suitable to be used in the four languages to assess the knowledge of dentists on diagnosing, recording and managing root caries.
CONCLUSIONS: The present questionnaire was validated and seems to be a good tool to evaluate how dentists diagnose, record, and manage root caries lesions both in its original (English) and its translated (French, German, and Italian) versions.
方法:一个专家小组开发了一个自我管理的问卷调查,包括三个领域:(1)牙医的诊断知识,录音,和管理根面龋;(2)有关其当前一般临床常规的信息;(3)其人口统计学。最初的英语[E]版本被翻译成三种不同的语言(法语[F],德语[G],意大利语[I]),随后由独立牙医翻译成英文。对于验证,82名牙医(每个翻译版本为20-22)接受在两个不同时间点(间隔1周)回答问卷。对数据进行质量检查。构造效度,内部可靠性,和类内相关性(ICC)进行评估。
结果:77名牙医两次填写问卷[E:17;F:19;G:19;I:22]。E的平均ICC(标准偏差)为0.98(0.03),F为0.90(0.12),0.98(0.04)对于G,I.和0.98(0.01),总体而言,测试-重测可靠性优异(平均ICC(SD):0.96(0.08)).此外,问卷显示出良好的内部可靠性(观察者间可靠性;Fleisskappa:总体:0.27(公平);E:0.30(公平);F:0.33(公平);G:0.33(公平);I:0.89(几乎完美))。
结论:问卷经过验证,适合以四种语言使用,以评估牙医的诊断知识,记录和管理根面龋齿。
结论:本问卷经过验证,似乎是评估牙医如何诊断的好工具,记录,并管理根龋病变的原始(英语)和翻译(法语,德语,和意大利语)版本。
