Background and aims: Safety behavior is a type of job behavior that promotes the health and safety of workers, clients, public and environment. One of the methods for assessment of safety behavior is the use of questionnaire but So far not provided a validated questionnaire in Iran for assessment of safety behavior. The present study was designed to develop a measurement tool for assessment of safety behavior. Methods: According to the previous studies, a draft of questionnaire with 25 questions was created. Face validity was done based on expert opinion and necessity, relevance, simplicity and clarity of the questions was evaluated. To assess the content validity, content validity ratio and content validity index of the questionnaire was calculated. Reliability of the questionnaire was tested with test-retest, Interclass correlation coefficient and cronbachchr('39')s alpha coefficient. Provided questionnaire tested on 315 employees of Qom province industries. Data analysis was performed using SPSS20. Results: Other than one question, for the rest of the questions CVR value was greater than zero. Mean of agreement ratio for relevance, simplicity and clarity of questionnaire was 0.91 and for necessity was 0.95. ICC index was equal to 0.752(P=0.009) and Pearson correlation coefficient between test and retest result was 0.619(P=0.02). In scout study Cronbachchr('39')s alpha coefficient was 0.766 and in the main study was 0.902. Mean score of Safety behavior was 3.78±0.66 and Safety behavior score has a significance inverse relationship with accident (P-value

Background and aims: Various factors affect the safety performance of employees and safety locus of control (SLOC) is one of the main determinants. People with an internal locus of control believe that they can control events and conditions and People with an external locus of control believe that events caused by factors such as chance, fate, environment and performance of other people. Therefore, to prevent accidents attention to the SLOC is very important. This study aimed to determine the SLOC and its related factors in employees of an industry. Methods: This cross sectional study was conducted on 172 employees of an industry in a central provinces of Iran. Data collection was performed using demographic-job and SLOC questionnaires. Data Gathering was performed in a semi-supervised manner. Data analyzed with SPSS software (version20) using independent T tests, Pearson correlation and liner regression. Results: The mean score of SLOC was 38.5±5.08 and was Larger than the mean intended to scale (µ=36) and was internal in the studied population. Chronic disease, smoking and Employment in second job have significant relationship with SLOC but other studied variables were not significantly associated with SLOC. Conclusion: Some variables may be influence the perception of people about level of control that they can have on events and in fact affect peoplechr('39')s safety locus of control. As a result, these variables could change safety locus of control and indirectly affect safety performance and accident occurrence.
