The aim of this study is to carry out an adaptation and validation of Adolescents' Expected Parental Reactions Scale in Spanish sample. This original scale was developed by Wyatt and Carlo (2002). The sample was composed by 632 adolescents, between 15 and 18 years, middle-class and both sexes. A confirmatory factor analysis was carried out to study construct validity and with Cronbach's alpha was studied internal consistence. The results showed that scale has good fit indexes to theoretical model proposed by original authors. On the other hand, a multigroup analysis was carried out to study the invariance of model through both sexes. The model was invariant, this supports the bifactiral structure of the scale that assessments adolescents' expected parental reactions on prosocial and antisocial behaviors.
