A Comparison of Aggression Between Musicians and Non- Musicians Groups of Iranian Police Force (NAJA)
In systems such as police force that any person is considered as an asset of the organization، noise pollution can lead to the behavioral abnormalities such as aggression that may cause occupational burnout. Therefore this study was conducted to compare aggression between Musicians and Non-Musicians groups of NAJA.
Materials And Methods
The present study was a cross-comparative research and tests were applied on all members of music group (n=42) of NAJA university. To access the control group، we selected 42 subjects and matched them with experimental group. To measure aggression we used Buss-Perry Aggression Questionnaire and for collecting demographic information we used a questionnaire designed by authors. Data processing was performed using student T-test and Pearson correlation coefficient by SPSS 20 software package.
The results of the comparison between two groups indicated that the score of overall aggression was significantly higher in music group than other one. The similar difference was also achieved for physical and verbal، anger، and hostility subscales of questionnaire (p=0. 001). Moreover، we found the significant positive relation between job history and aggression with Pearson correlation (p=0. 011). It means that the more year people work in music group، the more aggression they have.
Findings obtained from this study indicated the importance of high noise exposure effect on behavioral changes such as aggression among members of music group. The authorities should adopt and rigorously implement approaches to reduce and control exposure to this stressful environmental factor for the mentioned group. Allocation of suitable space for practice and providing acoustic space، proper scheduling for work and rest and psychological interventions to reduce aggression and increase compatibility in workplace are the most important approaches to achieve this goal.
