Between 2002 and 2006, the research team of the University of Psychology (Hipolito, Nounes, Tap) of Universidade Autonoma de Lisboa; validated and compared two self-esteem scales: the Rogers scale (Roses) and the New Toulouse Scale (NETES). Noting that these two scales were complementary, she decided to create a new scale resulting from the two others. This new scale was called SERTHUAL (Self-esteem Rogers, Tap and Hipolito) (2006). Subsequently, a Manual was published to present this scale (2011). We propose to present this scale on Researchgate, based on the copy of this Manual (2022)
