“…It consists of 10 items, five of them positively (e.g., On the whole, I am satisfied with myself) and five negatively (e.g., I feel I do not have much to be proud of) worded. Items were sequenced according to Gana et al (2005), and Tomás and Oliver (1999): P1, P2, N1, P3, N2, P4, P5, N3, N4 and N5.
