Egyptian results on the standard progressive matrices

Specific psychometric parameters of the Standard Progressive Matrices (SPM) for Egyptian undergraduate 205 males and 247 females were investigated. The 1 wk retest reliability was 0.82 (n = 44). A clear and high loaded factor was extracted from the 5 sets, indicating high internal consistency. The factor analysis of the SPM total score and 4 subtests of Thurstone's Primary Mental Abilities, that is, verbal comprehension, number, space, and inductive reasoning, yielded a general and high loaded factor, on which the SPM saturation is 0.77. This denotes significant and high concurrent validity. The mean score of Egyptian males was quite similar to that of British males, however, the mean score for the females was somewhat low. It is concluded that the SPM is a viable tool in the Egyptian context.
