“…While one paper stated that research was carried out in participants' ‘first language’ (Fernando, 2008), it was not clear whether this was the case with other papers. Research was carried out: with participants who were ‘fluent in’ or ‘spoke the language’ used (Phan et al ., 2004; Abeyasinghe et al ., 2012), in the ‘local language’ (Bass et al ., 2008), in the language of the target ethnic group (Ice & Yogo, 2005; Bolton et al ., 2007; Betancourt et al ., 2009 a ; Mcmullen et al ., 2012); in the preferred language of communication (Hinton et al ., 2011; Weaver & Hadley, 2011; Rasmussen et al ., 2014; Weaver, 2017); the most widely spoken language (Patel et al ., 1997; Kaiser et al ., 2013, 2015; Rasmussen et al ., 2015); the national language (Roberts et al ., 2006; Kaaya et al ., 2008; Hinton et al ., 2012 a , 2013, 2018; Kohrt et al ., 2016; Green et al ., 2018) and the more common language in a multi-lingual context (Mumford et al ., 2005; Miller et al ., 2006; Snodgrass et al ., 2017; Fabian et al ., 2018). In two studies, there was no discussion of what language the research was carried out in (Choi & Lee, 2007; Silove et al ., 2009).…”
