*2.1. Participants*

A nonrandom sampling of an intentional peak was used on a sample of 700 education degree students from two Spanish public universities: Universidad de Castilla-La Mancha and Universidad de Valladolid. The nonrandomised sample selection was due to accessibility to the rooms where participants were grouped. Despite the authorisation of the leading professor granting access to implement the instrument, only 12 professors gave authorisation to it. In consequence, it was possible to access a total of 13 group-rooms within 7 Faculties of Education integrated into 2 public universities offering educational degrees in 7 di fferent campuses. Participants' average age was 20.67 (SD = 3.19; range: 18–50). From the sample, 72.9% were female and 27.1% were male. Concerning university degrees, 45.9% of the participants were first-year students, 24.4% were second-year students, 18.3% were third-year students and 11.4% were fourth-year students.
