Summary

Abstinence-Contingent Wage Supplements to Promote Alcohol Abstinence and Employment was designed to promote alcohol abstinence and employment among adults experiencing homelessness and alcohol use disorder by providing financial incentives dependent on verified abstinence.

During the six-month program period, unemployed participants could earn up to 20 hours per week of wages for engaging in job-seeking activities with an employment specialist, at $10 per hour. Employed participants could receive wage supplements for verified hours worked, capped at $8 per hour for up to 40 hours per week. These payments were contingent upon maintaining alcohol abstinence, which was verified through wearable transdermal alcohol concentration (TAC) biosensor monitoring devices. 

Any alcohol use detected by the TAC device resulted in a temporary reset of the base supplement rate to $1 per hour. The rate increased by $1 per day for each day the participant remained abstinent and worked for at least five minutes until the maximum amount of $8 per hour was achieved.   

The pilot program was implemented in Baltimore, MD.

Cost information

How much did the program cost per participant?

The average total program cost per participant was $7,727 in 2024 dollars. This figure is based on cost information for this program reported in one cost study reviewed by Pathways to Work (for details, see the FAQ). This study received a rating of Good quality for the cost analysis.

How much did the program cost relative to its effects on participant outcomes? 

A cost-effectiveness analysis was conducted in the cost study reviewed, receiving a rating of Good quality. This study estimated a cost of $24,146 in 2024 dollars per participant employed in the past six months based on a six-month follow-up survey. This means that, relative to the comparison group, each additional program participant employed in the past six months due to the program cost $24,146. The study also estimated a cost of $1,606 in 2024 dollars per additional day of participant employment in past 30 days based on a six-month follow-up survey.

Cost information is not directly comparable across programs due to differences in the categories of costs reported and program length. Cost information is not an official price tag or guarantee.
