Construct Validity, Reliability And Grading Scale Of The General Self-Esteem Test (Gset) In Teenage Students From The Interior Of Perú

Abstract

The construct validity and reliability of the General Self-Esteem Test (GSET) have been studied. Likewise, a grading scale has been developed for teenage students who reside in the interior of Peru. The participants were 1,171 teenage of both sexes, whose ages ranged from 12 to 18 years. The results demonstrate that the test meets the goodness-of-fit indices and is close to the incremental ones, which partially validates the structure of the original four-domain model. In relation to reliability, the Split half of .72 and the KR20 of .73 allow us to affirm that the reliability is high, therefore, the test maintains good internal consistency. As a final contribution, a unified scale is prepared, because the magnitude of the effect, determined by Cohen's d, calculated for the Mann Whitney U, falls in the range of no effect.
