“…In addition to ML, other methods more in line with the distribution of PANAS scores and the categorical nature of its indicators have been used. Among these, a method widely used in previous PANAS CFAs is the Weighted least squares means and variance adjusted (WLSMV) estimator, applied in 6 of the twenty-six previous studies (23.07%; Caicedo-Cavagnis et al, 2018;Díaz-García et al, 2020;Heubeck & Wikinson, 2019;Heubeck & Boulter, 2020;Ortuño-Sierra, Santarén-Rosell, Pérez de Albéniz, & Fonseca-Pedrero, 2015;Vera-Villarroel et al, 2017). Another alternative applied has been the Robust Maximum likelihood (RML) applied in 6 out of 26 previous studies (23.07%; Jovanovic´& Gavrilov-Jerkovic´, 2015;Lim, Yu, Kim, & Kim, 2010;Merz & Roesch, 2011;Merz et al, 2013;Narayanan, Abdelrasheed, Nasser, & Menon, 2019;Seib-Pfeifer, Pugnaghi, Beauducel, & Leue, 2017); and the Diagonal weighted least squares (DWLS) estimator, used by 4 of the 26 previous studies (15.38%; Buz, Pérez-Arechaederra, Fernández-Pulido, & Urchaga, 2015;Leue & Bauduquel, 2011;Santángalo et al, 2019;Tuccitto, Giacobbi, & Leite, 2009).…”
