<qa>  What is the name of the three components that will be evaluated?The formal evaluation of TG will begin in the fall of 2015 and will utilize the principles of Multiphase Optimization Strategy MOST; Collins et al., 2009 for intervention development and a fractional factorial design to evaluate the relative effectiveness of different components within the intervention. Three components will be evaluated: 1 A Lakota language enhancement Lakota, 2 a Facebook social media enhancement FB, and 3 substance use resistance skill content SU. A total of 24 intervention groups will be randomly assigned to one of 4 MOST design conditions, with the content of each condition determined using SAS PROC FACTEX, as recommended by Collins, et al, 2009. All 4 conditions will consist of the basic TG program, each supplemented by one or more of 3 components designated above: Condition A will include the substance use resistance content SU; no Lakota or FB; Condition B will include the FB social media supplement FB; no Lakota or SU; Condition C will include the Lakota language enhancement Lakota; no FB or SU; and Condition D will include all three components Lakota FB SU.
