“…Based on this model, a number of sociodemographic predictors of local language acquisition have been identified, including gender (e.g., Beiser & Hou, 2000;Kristen, Mühlau, & Schacht, 2016;Van der Slik, Van Hout, & Schepens, 2015), length of stay in the country of residence (e.g., Carliner, 2000;Van Tubergen & Kalmijn, 2005), age of arrival (e.g., Kristen et al, 2016), and premigration education level (Beiser & Hou, 2000;Hayfron, 2001;Hou & Beiser, 2006;Van Tubergen, 2010). Mental health has also been studied often among immigrants and refugees (e.g., see Fazel et al, 2005;Porter & Haslam, 2005), and good mental health has frequently been associated with better local language acquisition (Beiser & Hou, 2001;Chiswick & Miller, 2001;Van Tubergen & Kalmijn, 2005; for exceptions, see Van Niejenhuis, Van der Werf, & Otten, 2015;Van Tubergen, 2010). Although these findings are informative, we argue that this literature fails to recognize that psychological and individual differences-in addition to situational and external factors-could also influence local language acquisition among migrants (Dörnyei, 2005).…”
