مقایسه تکانشگری، مخاطره جویی و همدلی (I7) ساختار در زبان انگلیسی و نمونه اسپانیایی : تجزیه و تحلیل از مدل های مختلف معادلات ساختاری

The present study analyzed the factorial structure of the I7 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 I7 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 I7 long and short versions with impulsiveness scales of ZKPQ, BIS-10 and SPSRQ.
