^{^a}

Based on a software engineering estimate to reproduce intervention software in 2012 (±10%).

^{^b}

Estimating $500 cost of a tablet or $1000 to $1200 cost of a laptop.

^{^c}

Based on the costs experienced to train staff in motivational interviewing for the SafERteens intervention (±10%).

^{^d}

Median 2011 salary from the Bureau of Labor and Statistics (BLS), adjusted to 2012 dollars.¹²^,¹⁴ (±10%).

^{^e}

Estimated cost of benefits in 2012 from the Bureau of Labor and Statistics¹³ (±10%).

^{^f}

Salary + benefits.

^{^g}

Based on the SafERteens experience, we predicted a 35% increase in daily social worker time to deliver the 30-minute intervention at an ED with a volume of 7884 adolescents per year and 80% screening positive for violence (±10%).
