Through the qualitative and quantitative study of face validity, content validity index calculation and judging the quality via a 14-member panel of experts and validity by performing exploratory factor analysis-with the agreement reliability (coefficient alpha) and test-retest method of estimating was approved. Results: A total of 50 males, first three items need to be corrected with the number 45 on the calculation of the index scores of items (with quantity greater than 1.5) with CVI greater than 0.07 and CVR higher than 0.08 down found. As demonstrated, good homogeneity of subdirectories than the average correlation between questions 0.35 (P<0.001). By calculating Cranach's alpha reliability of the tool, 0.83 was verified and the results show test-retest stability of the questionnaire and its subdivisions. Conclusion: The evidence of the strength of the factor structure and the reliability of an instrument can be developed to provide a tool for research, teaching and practice of health workers are of interest.
