METHODOLOGICAL INFORMATION 
............................


1. Description of the methods for collection/generation of data: 

- Data were collected through an online 4-points Likert-type questionnaire during academic years from 2018/2019 to 2021/2022. Describa metodolog’a empleada para generar el conjunto de datos. 
- Aporte la cita bibliogr‡fica sobre el art’culo (publicado o no) por el cual se han generados los datos de investigaci—n. Imporante: T’tulo de art’culo si ya se sabe.


2. Data processing methods
- Reverse-worded items were re-coded. All items phrased in a negative sense (items 4A to 4N) were inverted. In the re-coded items, a "totally disagree" score now signifies a stronger agreement with the negatively expressed statement.

3. Software or instruments needed to interpret the data:
- R-based free software, JAMOVI (version 2.3.21)
- R-based free software, JASP (version 0.17.2.1) 

FILE OVERVIEW 
-------------------------------------------
