Abstract: Objective To establish the norm of Cattell's of 16 Personality Factor Questionnaire(16PF)of Uygur Version and to assess the reliability and validity of the 16PF among Uighur police.Methods The 16PF of Chinese version was translated into Uygur version.Using stratified random sampling method,218,172,and 3 817 Uygur police were selected from 15 prefectures in Xinjiang Uygur Autonomous Region for prediction,test-retest,and real test,respectively.The reliability and validity of 16PF Uygur version were analysed and the norm of the 16PF was constructed.Results The total score of Uygur version 16PF was correlated with the scores of most of the items with the coefficients of 0.415-0.689(P<0.01 for all).The questionnaire presented a good degree of differentiation.The overall internal consistency coefficient of the questionnaire was 0.827,the half reliability was 0.782,and the retest reliability was 0.600,indicating good reliability of the questionnaire.The validity test showed that every personality item could efficiently reflect its factor and the correlation coefficients among the 16 personality factors ranged from-0.375 to 0.459,with every factor being independent of other factors,demonstrating a good validity of the questionnaire.There were significant differences in warmth(A),reasoning(B),dominance(E),liveliness(F),rule-consciousness(G),social boldness(H),apprehension(O),openness to change(Q1),self-reliance(Q2),and tension(Q4)between Uygur policemen and policewoman(P<0.05 for all).The levels of A,B,emotional stability(C),H,vigilance(L),abstractedness(M),Q1,Q2,and Q4 were significantly different among the police with different education background(P<0.05 for all).The police engaged in different duty posts showed differences in A,E,F,and M(P<0.05 for all).ConclusionThe 16PF of Uygur version has good reliability,validity and differentiation when applied among Uygur police.The norms of Uighur version 16PF are different among the Uighur police of different gender,education,and duty post.
