4-2. Psychometric Analysis
4-2-a. Factors and Corresponding Survey Items for the Executive Survey
Based on a series of factor analyses, parallel analyses, and item analyses, 12 factors were identified for the executive survey. Factors and the correspondent survey items of each factor, and descriptive statistics (alpha coefficient, possible range, observed range, mean, standard deviation, and number of respondents) are reported in Table 8. See Appendix 5 for definitions of the 12 factors.

Note. Alpha = alpha coefficient, which is computed only for Factors consisting of 2 or more items. It ranges from 0 to 1, with values closer to 1 indicating that the set of items measures well a single Factor. PR = possible range of scores. OR = observed range of scores. Mean = an arithmetic average of the sum of the individual responses to the set of items for each Factor based on the survey respondents. SD = standard deviation, which is a measure of how widely the respondents' scores differ from the mean score. The larger the standard deviation, the more spread are the respondents' scores. N = number of respondents who provide valid responses for each factor. N may differ across factors due to missing responses.
Summary of Table 8.
Overall, alpha coefficients ranged from 0.82 to 0.92, which were satisfactory. Perini safety climate, employer safety management, safety practice, and Perini safety program exhibited narrower observed range of scores than the possible range of scores. In other words, responses toward these four factors were significantly skewed in a positive direction.
4-2-b. Mean Comparisons within the Executive Survey
Mean comparisons of each of the 12 factors of the executive survey were conducted based on years worked in the construction industry (less than 26 years vs. greater or equal to 26 years). No statistically significant differences were found.
