Discrimination, reliability and validity of the factory scale of happiness in the university student

Abstract

This article describes the analysis of a happiness measurement scale, consisting of 27 Likert items with five alternatives. The scale was administered to 237 students of the University of the Autonomous Regions of the Nicaraguan Caribbean Coast- Las Minas University campus, men and women, from 16 to over 36 years of age. The item-test analysis found highly significant correlations for each of the reagents (p <.001), which indicates that the items measure indicators of the same construct. Most of the items have a discrimination index of ≥ 0.4, which indicates that they discriminate positively in a high degree, that is, they are well understood and understood for the majority. The reliability scale has a high internal consistency α = 0.895 which means that they can be interpreted in the sense that all the items measure indicators of the same construct (happiness) and that they favor to measure it effectively, since they have or are part largely from the main feature, happiness. Likewise, a direct relationship is shown between the variables associated with happiness (r> 0), but there is also a high correlation with significance at the 0.01 level. The happiness scale has good factor validity. Seven factors were extracted: F1. with 9 items; F2 with 10 items; F3 has 5 elements, factors 4,5 and 6 respectively, only one item and factor 7, it does not present exclusive factor loads, rather it has significant loads (greater 0.24) of items I17 and I15, items that are respectively located and established in the first factors because they converge better in them. The factor loads of each variable, in each of the factors, range between 0.236 and 0.791.
