“…Register-Mihalik et al 2 recommended that in order for athletic trainers (ATs) to design more effective interventions, they should consider factors at multiple levels, such as community or interpersonal levels of influence. Although CRB researchers have referred to the Bronfenbrenner SEM, 1,2 have tested part of the model, [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] or have adapted the model by collapsing across systems categories, 1,2 to our knowledge, no investigators have used the full Bronfenbrenner model to assess factors that contribute to CRBs. Consideration of microsystem, mesosystem, exosystem, and macrosystem factors, in addition to individual-level factors, is critically important if novel interventions are to be designed, implemented, and examined for effectiveness.…”
