目的:编制癌症高危因素及先兆表现清单并测定其信效度。方法:根据癌症发生最常见的高危因素及先兆表现建构理论维度,参考前期研究、C型行为特征及量表编写条目,随机抽取693例癌症患者进行测定,请患者、129位亲属和103位医护人员做条目重要性评分,并请706位人口统计学资料与患者类似的健康人填写清单。结果:①经过项目分析和探索性因素分析,最后保留19个条目,归纳为躯体、心理、社会因素、生活习惯4个因子(维度)。②清单具较好的结构效度,4因子累计解释方差变异的77.92%;比较患者与健康人群的四个维度均分和总均分有显著性差异。③四个维度均分和总均分的重测信度分别为0.82、0.76、0.80、0.77和0.83;Cronbachα分别为0.76、0.79、0.83、0.80和0.86;分半信度为0.90。结论:症高危因素及先兆表现清单具较好的效度和信度,在临床上有一定的实用价值。
OBJECTIVE: To compile a list of risk factors and precursors for cancer and determine their reliability and validity. Methods: According to the most common risk factors of cancer and the precursors to construct the theoretical dimension, 693 cancer patients were randomly selected according to the pre-study, C-type behavioral characteristics and scale entry, and the patients, 129 relatives and 103 medical care The staff made the item importance score and asked 706 people who had similar demographic information to fill in the list with healthy people. Results: ①After project analysis and exploratory factor analysis, the last 19 articles were reserved, which were summarized as four factors (dimensions) of body, psychology, social factors and living habits. ② The inventory has good structural validity, and the four factors explain 77.92% of the variance variance; the four dimensions of the patients and the healthy population have significant differences in mean and overall scores. (3) The test-retest reliability of the four dimensions and the average total score were 0.82, 0.76, 0.80, 0.77 and 0.83, respectively; Cronbachα were 0.76, 0.79, 0.83, 0.80 and 0.86 respectively; Conclusion: The high risk factors and threatened manifestations have good validity and reliability, and have certain practical value in clinic.
