To characterize the factorial structure, and psychometric properties of the Brazilian version of the Modified Reasons for Smoking Scale (MRFSS).
Three hundred eleven smokers (214 male; mean age: 37.6 +/- 10.8 years), who had gone to the 'Hemocentro de Ribeirão Preto' to donate blood , answered 21 items of the Brazilian version of the MRFSS, the Fagerström test, and the Criteria of Brazilian Economic Classification. Scores of the MRFSS items were evaluated regarding their grouping, employing exploratory factorial analysis. The influence of clinical features on scores of the final factorial solution was also investigated.
Factorial analysis led to the characterization of 7 factors: addiction, stimulation, pleasure to smoke, handling, social smoking, tension reduction/relaxation, and habit/automatism. Four questions were excluded due to factorial loadings of less than 0.3. The final version was formed by 17 items showing a minimal factorial loading of 0.376. Women showed high scores of addiction (3.5 X 3.1), tension reduction/relaxation (4.1 X 3.5), and handling (2.4 X 2.0). Low scores of the Fagerström test were associated to low scores in addiction, tension reduction/relaxation, habit/automatism and stimulation.
The Brazilian version of the MRFSS, comprised of 17 items, exhibits satisfactory factorial structure, and psychometric properties.
描述巴西版改良吸烟原因量表（MRFSS）的因子结构和心理测量特性。
311名前往“里贝朗普雷图血液中心”献血的吸烟者（214名男性；平均年龄：37.6±10.8岁）回答了巴西版MRFSS的21个条目、法格斯特罗姆测试和巴西经济分类标准。采用探索性因子分析对MRFSS条目的得分进行分组评估。还研究了临床特征对最终因子解得分的影响。
因子分析确定了7个因子：成瘾、刺激、吸烟愉悦感、操作、社交性吸烟、减轻紧张/放松和习惯/自动化。由于因子载荷小于0.3，排除了4个问题。最终版本由17个条目组成，最小因子载荷为0.376。女性在成瘾（3.5×3.1）、减轻紧张/放松（4.1×3.5）和操作（2.4×2.0）方面得分较高。法格斯特罗姆测试得分低与成瘾、减轻紧张/放松、习惯/自动化和刺激方面的低分相关。
由17个条目组成的巴西版MRFSS具有令人满意的因子结构和心理测量特性。
