preparation and validation of iranian police job satisfaction inventory (ipjsi)

objectives: the present research aims to prepare an iranian police job satisfaction inventory (ipjsi) by using confirmative factor analysis as well as to evaluate the validity and reliability of it. method: a group consisting of 2933 iranian police employees chosen by stratified random sampling method from a number of police departments throughout the country completed the ipjs inventories. validity of the model was examined using a structural validation method (confirmatory factor analysis). reliability of the ipjsi proposed was also investigated by using test-retest method along with internal consistency method of cronbach’s alpha coefficient. results: the confirmative factor analysis indicated that 45 questions of the proposed inventory formed 15 distinct factors. test-retest method, the reliability factors of the ipjsi were identified as ranging between 0.61 to 0.84 for all the existing subscales and 0.73 for whole inventory. otherwise, using the internal consistency method of cronbach’s alpha coefficient, the reliability factors of the proposed ipjsi were calculated ranging between 0.57 to 0.70 for all the existing subscales and 0.91 for whole inventory. conclusion: iranian organizations are recommended to use ipjsi instead of prevalent job satisfaction inventories such as job descriptive index minnesota satisfaction questionnaire. unfortunately, such tools are not able to assess the police staff's job satisfaction correctly.
