Preliminary estimates of cost-effectiveness

Fixed costs
	Hours	Personnel*	Cost**	Cost/participant
Two day-long initial training	16	SI, PI, SP	16*$32+$500x2+16*100=	$3112/40=$77.80
Mock one-on-one sessions	10	SI, PI	10*$32 + 10*$50x2=	$1320/40=$33.00
Hour-long debriefing sessions: weekly × 1 month then monthly × 11 months	15	SI, PI, SP	15*($32+$50x2+$100)=	$3480/40=$87.00
Listening to tapes of pilot intervention sessions	8	SI	8*$32=	$256/40=$6.40
Total fixed costs per person = $77.80+33.00+87.00+6.40=$204.20
Variable costs (per participant)
	Hours	Personnel	Cost
6 One-on-one sessions, 35 minutes + 10 min prep	0.75	SI	6*0.75*$32=$144
6 Group sessions, 1 hour + 10 minute prep	1.2	SI, PI	6*1.2*$32 + 100=$330.40
Reminder calls, 2.4 hours total	2.4/10=0.24	SI	0.24x$32=7.68
Snacks	---	---	$29.75
Travel vouchers (gas, bus)	---	---	$45.40
Participant manuals	---	---	$19.40
Total variable costs per person = $144+33.40+7.68+29.75+45.40+19.40=$279.63

^*SI = staff interventionist. PI = peer interventionist, SP=supervising psychologist.

^**Assuming staff interventionist rate = $32/hour including fringe, peer interventionist is paid a combination of hourly and flat rates ($500 for two-day training, $50/hour for mock sessions and debriefing sessions, $100/group), supervising psychologist is paid $100/hour
