From OPRE: This impact report from the Behavioral Interventions to Advance Self-Sufficiency (BIAS) project presents findings from four tests of behavioral interventions intended to increase the percentage of parents who made child support payments and the dollar amount of collections per parent in Cuyahoga County, Ohio. These findings demonstrate that low-cost, low-effort behavioral interventions can improve child support outcomes. However, interventions that are more intensive may be necessary to increase overall child support collection amounts, perhaps because some parents have a limited ability to pay.
