J. Kozeny, FACTOR STRUCTURE OF THE EYSENCK PERSONALI TY QUESTIONNAIRE (EPQ R) - EXPLORATORY ANALYSIS/, Ceskoslovenska psychologie, 38(2), 1994, pp. 112-118
The Czech version of the Eysenck Personality Questionnaire (EPQ/R) was
subjected to psychometric analysis based on responses of 2212 subject
s (males=1203, average age 28.2, SD=11.3; females=1009, average age=28
.9, SD=10.9). The exploratory factor analysis (maximum likelihood, ext
raction according to postulated four dimensional space, rotation to va
rimax criterion) accounted for 19.5% of variance. The factor structure
approximated satisfactorily the simple structure for E, N and L scale
s only. The internal consistency analyses of the EPQ/R scales suggest
item redundancy. Fewer items might provide more efficient measurement.
The MANOVA of the EPQ/R scales using sex and age intervals (16-20, 21
-30, 31-40, 41-55 ys) as classification variables revealed the statist
ically significant interaction of the independent variables. The means
, SD, skewness, and curtoisis of the scales distribution are Presented
with regard to sex and age intervals.
