The current study was designed to evaluate the efficacy of the theory of planned behavior-based intervention to improve workers safety climate in industrial city of Qazvin in the first half of 2010.

  Methods : A number of 75 workers in each of the control and intervention groups participated in a quasi experimental study. With respect to the fact that the changes of safety climate usually take place in the long term, and for the longer follow-up of participants, data were collected through self-report questionnaires in three different time intervals including initial followed by , 3 and 6 months after the intervention . The intervention consisted of four training courses with 8-15 trainees in each group and its duration was 45-69 minutes. The data were entered into SPSS 16.0 software and were analyzed using statistical tests.

  Results : The score of Management commitment was significantly increased in the three and six month evaluation in intervention group (p< 0.001). Also, results showed a significant increase in other dimensions such as safety communication, secure environment , responsibility, risk perception , safety climate (P<0.05). Results also indicate a significant change in mean scores of attitude , subjective norm (P<0.05), perceived behavioral control (P<0.001) and attempted (P<0.05) in the intervention group and no significant change in these variables in the control group.
