“…Lastly, a recent study (Lin et al, 2021) across 11 countries (i.e., Bangladesh, Brazil, Cuba, France, Iran, Italy, Japan, New Zealand, Pakistan, Taiwan, United Kingdom), primarily based on datasets from previous studies on the psychometric properties of the FCV-19S, showed that a one-factor solution of the FCV-19S indicated partial scalar invariance across countries and scalar invariance across gender and age groups (i.e., child, young to middle-aged adult, older people). Other studies also demonstrated invariance between genders (Piqueras et al, 2021;Sakib et al, 2020) and healthcare workers versus nonhealthcare workers (Huarcaya-Victoria et al, 2020). Further, two studies showed invariance between age groups (younger vs. older, with the specific age threshold varying across studies; Huarcaya-Victoria et al, 2020;Piqueras et al, 2021;Sakib et al, 2020).…”
