Hello and please forgive my english,

I' m using spss in an index of empathy (Bryant, 1982) with dichotomous answers (yes=1/no=0). I'm trying to split the 22 question-test in a three-way version (Lasa Aristu et al. 2008), with several questions per category. I calcutale the cronbach's a=,863 The problem is that the cronbach of each separate category of questions is lower than the ,863 of the whole test. (,726 ,804 ,730) Is that possible or am I doing sth wrong??

Thank you for your answers.
