To formulate the standard measuring tool for the evaluations on fire-heat syndrome in oral cavity by means of Chinese medicine (CM).
The measuring scale for fire-heat syndrome in the oral cavity by means of CM was investigated by symptom collection, item pool formulation, item selection, pre-investigation, evaluations on the reliability, validity and reactivity of the measuring scale, according to the principles for measuring scale design and under the guidance of CM theories.
The measuring scale was composed of two integrative parts: the self-filling section and the interview section. As far as the reliability was concerned, the total Cronbach α coefficient of the measuring scale was 0.866, the total test-retest reliability coefficient was 0.726 and the split-half reliability coefficient was 0.851. As far as the validity was concerned, the scores for the subjects of fire-heat syndrome in oral cavity and healthy people in their oral cavity in the items of symptoms were statistically different (P<0.01); three common divisors were extracted according to the theoretical dimensions, the accumulated contribution rate was 63.468%. As far as the reactivity was concerned, the difference between the symptom scores before and after the test in which 31 subjects used the Chinese herb toothpaste was statistically significant (P<0.01).
This measuring scale has relatively good reliability, validity and reactivity, and it can be used in an objective quantitative evaluation on patients suffering from fire-heat syndrome in oral cavity, and thus lay the foundations for the evaluations on the therapeutic effects of Chinese herb toothpaste on fire-heat syndrome in oral cavity.
研制中医口腔火热证计量评价工具。
采用中医火热证口腔症状采集、条目池形成、条目筛选、预调查、计量学考评等方法，以计量学理论为指导，中医理论为依据，研制中医口腔火热证计量评价工具。
计量评价工具由自评和他评两部分组成。该计量评价工具的信度考评：总量表 Cronbachα系数为 0.866，重测信度为 0.726，分半信度为 0.851。效度考评：口腔火热证组和口腔正常组各症状条目得分差异均有统计学意义（P<0.01）；按理论维度提取 3 个公因子，累计方差贡献率为 63.468%。反应度考评：31 例患者使用中药牙膏前后症状评分差值比较，差异有统计学意义（P<0.01）。
该计量评价工具具有较好的信度、效度和反应度，可对口腔火热证患者进行客观的定量评价，为中药牙膏治疗口腔火热证的疗效评价奠定了基础。
