From semantic definition to items through test´s and items` specifi-cations: construction of ERCE Scale

The aim of this work is to stress the relevance of all the previous steps before items construction (semantic definition, test and items specifications, experts judges, etc.). There are few works in attitude tests construction where all the steps before items where showed, despite its importance is remarked by standards (AERA, APA, NCME, 1999). The process of ERCE Scale construction is showed as an example in that way. ERCE (De los Santos-Roig, 2009) was developed to assess illness representations which is a construct inserted in Common Sense Model of Illness (Leventhal et al, 1997). In the second part of this work qualitative items analysis of scale is showed and discussed.
