“…There are two possible reasons for the statistically significant differences: the first reason -and the one put forward within the 'Introduction and Hypotheses' sub-section, above -suggests SIT processes and close affiliation to Welsh culture and the community (Tajfel & Turner, 1979;Hendry, Mayer, & Kloep, 2007;Jones, 2002;Coupland, Bishop, Evans, & Garrett, 2006) provided protection for FLWs against depression (e.g., Postmes, Wichmann, van Valkengoed, & van der Hoef, 2018), loneliness (e.g., Travaglino et al, 2020), and social anxiety (Haslam et al, 2019); conversely, a second reason would suggest FLEs with a lower Welsh language ability are disadvantaged in terms of feeling potentially marginalized within Welsh/Bilingualmedium schools (e.g., Šolak & Dragičevič, 2021). Although Chapter Six goes into greater detail, for the purposes of reinforcement, it is worth recalling how perceptions of marginalization, peer isolation, and feeling left out correlate to higher levels of depression, loneliness, and social anxiety (Thornhill et al, 2021;Ahn, Kivlighan, & Hill, 2021;Chen et al, 2022b;Anjum et al, 2022;Evans & Fisher, 2022;Handing et al, 2022;Gong et al, 2022;Neto, Quintana-Orts, & Neto, 2022;Niu et al, 2022;Leary, 2015;Flick et al, 2022;Ettekal et al, 2022;La Greca & Harrison, 2005). For contrasting reasons, the referenced literature has suggested differences in FLWs' and FLEs' depression, loneliness, and social anxiety scores with FLEs recording the higher values.…”
