Abstract:
ObjectiveTo develop the group intelligence scale for Military Personnel ( Part B),and examining its reliability and validity of the scale.MethodsFollowing the intellectual shock theory,crystal and fluid intelligence theory,the group intelligence Scale for Military Personnel (Part B) had been constructed,which including two subscales,each subscale was divided into two subtests.The data was collected in 1200 military personnel who were chosen by random cluster sampling,then employing SPSS17.0 and AMOS7.0 for item analysis,reliability and validity,analysis of confirmatory factor.Resultsthe subtests' average index of difficulty was 0.55 ( 0.42 ～0.75 ) ; Discrimination index was 0.44 (0.33 ～ 0.52) ; the test-retest reliability between subtests and total scale ranged from 0.796 to 0.891 ; Cronbachs'a coefficient ranged from 0.619 to 0.892; and the split-half reliability ranged from 0.538 to 0.844; exploratory factor analysis revealed that four factors of the scale (including normal knowledge and generalizability,insight and word explain,picture completion and figure inference) could explain 59.067％ of total variance.Furthermore,analysis of confirmatory factor indicated that the four factors model established in the present study fitted the sample data well.ConclusionThe item analysis,reliability and validity of the newly developed group intelligence scale for military personnel (part B) can meet the basic requirements of psychometrics.
