“…The components of this pilot aftercare intervention (i.e., daily self-monitoring/feedback texts, wellness recovery tips, and substance abuse education and social support resource information texts on weekends) were influenced by formative work conducted with youth in treatment (see Gonzales et al, 2012; Gonzales et al, 2012; Gonzales et al, 2013; Gonzales et al, 2013). Previous studies that have used formative research for intervention development with youth populations challenged by diverse behavior issues (Mathews, Everett, Binedell, & Steinberg, 1995; Nichter, Nichter, Thompson, Shiffman, & Moscicki, 2002; Vu, Murrie, Gonzalez, & Jobe, 2006) have shown such approaches to be effective for behavior change as it includes culturally-relevant reflection and experiences of the targeted groups most affected.…”
