Abstract :

The aim of this study was investigating of practicality, Reliability and Validity of direct and Indirect Prisoner Behaviors Checklist-Scaled version (DIPC-SCALED-r Ireland 2007) in non-political crime central prison in Hamadan city. A sample of 500 prisoners’ randomly was selected. Checklist included two forms of 49 questions to measure the victimization and the 58 questions to measure bullying. To obtain validity of questionnaire used two methods: test-retest and internal consistency (Cronbach's alpha). The correlation coefficient for the victimization form was r =0.47 and for bullying form was r =0.43 which were significant in P < 0.001. Cronbach alpha coefficient computed for the victimization form 0. 92 and for the bullying form 0. 90. After removing 12 items of the first form and to items from second form which had weak correlation, validity coefficients became more significant: 0.90 and 0. 89. To check the validity of log structures and what factors that is saturated, the factor analysis method was used. KMO and Bartlett's sizes in two form of questionnaire indicated conditions for factor analysis was run .After exclusion of inappropriate questions by using principal component analysis and rotation matrix Promax and according to scree plot and percentage variances of the series form factor and 5 being the victim of bullying form the five factors were extracted. In the present study to check the validity of questionnaire used the criteria validity method. The results showed the coefficient for the form of victimization was r=0.45 and for the form of bullying was r=o.53.
