“…The validity evidence based on the internal structure were obtained through the CFA, the results of which show appropriate fit indices for the unidimensional model, that is, the WHO-5 items translated into Collao Quechua made up appropriate indicators to measure subjective well-being as the only latent characteristic. This confirms what previous studies have found at national [ 19 ] and international [ 20 , 21 , [28] , [29] , [30] ] level that it is consistent with the original version designed by the World Health Organization [ 31 ] as a single dimension instrument considering five indicators to measure well-being in primary assistance. Additionally, taking into account the study where [ 19 ] suggest the correlation of error in items 1 and 4, whereas the research of [ 29 ] suggests the correlation of error in items 3 and 4, the modification indexes were analyzed, and it was found that it was not necessary to model the correlation among the residuals of the items translated into Collao Quechua.…”
