分别参加第一届和第二届“亚洲肺尘埃沉着病强化朗读者”（AIR Pneumo）培训课程的29名医生（A1组）和24名医生（A2组），以及参加巴西培训课程的22名医生（B组）参加了60部电影的阅读考试。本研究的目的是首先探讨医师阅读尘肺胸部X光片熟练程度的因素结构，其次探讨各组间因素得分的差异。对所有被试（考生组）的阅读成绩进行探索性因素分析。分析了4个因子以构建8个指数：尘肺特异性、大阴影特异性、胸膜斑特异性和小阴影形状分化加载在因子1上;尘肺敏感性和大阴影敏感性加载在因子2上;胸膜斑敏感性加载在因子3上;灌注增量一致性加载在因子4上。4-比较三组之间的因子分。A1组和A2组的因子2得分显著高于B组。4个因素可以反映尘肺X线片阅读熟练程度的4个方面，提示4个因素得分也可以适当地评价所获得的技能。
29 physicians (A1-Group) and 24 physicians (A2-Group) attending the 1st and 2nd "Asian Intensive Reader of Pneumoconiosis" (AIR Pneumo) training course, respectively, and 22 physicians (B-Group) attending the Brazilian training course took the examination of reading the 60-film set. The objective of the study was firstly to investigate the factor structure of physicians' proficiency of reading pneumoconiosis chest X-ray, and secondly to examine differences in factor scores between groups. Reading results in terms of the 8-index of all examinees (Examinee Group) were subjected to the exploratory factor analysis. A 4-factor was analyzed to structure the 8-index: the specificity for pneumoconiosis, specificity for large opacities, specificity for pleural plaque and shape differentiation for small opacities loaded on the Factor 1; the sensitivity for pneumoconiosis and sensitivity for large opacities loaded on the Factor 2; the sensitivity for pleural plaque loaded on the Factor 3; the profusion increment consistency loaded on the Factor 4. 4-Factor scores were compared between each other of the three groups. The Factor 2 scores in A1 and A2 groups were significantly higher than in B-Group. Four factors could reflect four aspects of reading proficiency of pneumoconiosis X-ray, and it was suggested that 4-factor scores could also assess the attained skills appropriately.
