Comparison of impulsiveness, venturesomeness and empathy (I 7) structure in English and Spanish samples: Analysis of different structural equation models

Abstract

The present study analyzed the factorial structure of the I 7 Impulsiveness questionnaire (Impulsiveness, Venturesomeness and Empathy) with a Spanish sample of 742 males and 1.075 females, through exploratory and confirmatory factorial analysis. In relation to the original English data, a three-factor structure showed global congruency coefficients of 0.92 and 0.94 for men and women. Venturesomeness had a modest congruency for males (0.83). A cross-validation analytical strategy showed that the 24-item I 7 was invariant only for the female sample. A subsequent exploratory factor analysis with 24 items showed a sound factor structure. The 24-item version showed the best and most robust structure and similar internal consistency coefficients in regard to the 54-item version. No important differences were founded between I 7 long and short versions with impulsiveness scales of ZKPQ, BIS-10 and SPSRQ.
