“…Studies that have examined the relationship between ethnic identity and youth outcomes among other racial/ethnic minority groups have indicated that higher racial/ethnic identity achievement was linked to a range of positive outcomes, including lower internalizing problems and externalizing behaviors, higher self-esteem, increased academic achievement, and improved sense of mastery (Bennett, 2006; Constantine & Blackmon, 2002; Phinney & Alpuria, 1990). However, although several studies have found the protective effect of ethnic identity among American Indian youth (e.g., Jones & Galliher, 2007; Whitesell, Mitchell, Kaufman, & Spicer, 2006; Whitesell et al, 2009), others have reported no associations between ethnic identity and psychological adjustment (Adams, Fryberg, Garcia, & Delgado-Torres, 2006; Brown & Smirles, 2005; LaFromboise, Medoff, Lee, & Harris, 2007).…”
