“…International studies have shown that in the United States, Turkey and Brazil, and in African populations, the MLQ (Steger et al, 2006) has measurement invariance across age groups (most of the subjects were divided into early, middle and late stage adulthood) and across cultures; configural invariance, metric invariance and scalar invariance were found, and the corresponding results supported the idea that the two-dimensional structure of the MLQ has the same psychological structure in different age stages (Boyraz, Lightsey, & Can, 2013;Damásio & Koller, 2015;Steger, Oishi, & Kashdan, 2009;Temane, Khumalo, & Wissing, 2014). However, in China, although the scores of meaning in life are significantly different for teenagers than for other age groups (Qin & Wang, 2012;Qin, Wang, & Zhang, 2013), previous findings were not based on measurement invariance.…”
