“…However, most MRs involving youth and nonparental adults occur naturally outside of a program setting (Bruce & Bridgeland, 2014). These natural MRs may be more enduring than those supported by formal programs possibly because they are more authentic, developmentally focused, and embedded in stable social networks (Black, Grenard, Sussman & Rohrbach, 2010;Schwartz, Rhodes, Spencer & Grossman, 2013). Not surprisingly, an emerging body of evidence has shown wide ranging positive effects associated with youth involvement in natural MRs including improvements in mental health (Hurd & Zimmerman, 2010;Zimmerman, 2010), stronger interpersonal relationships with significant others (e.g., parents; Hurd & Zimmerman, 2014), reduced risky behaviors (Zimmerman, 2010) and higher paying and more intrinsically rewarding careers in early adulthood (McDonald & Lambert, 2014;Timpe & Lunkenheimer, 2015).…”
