Abt SRBI
To ensure that production goals are met, field representatives will transmit screening data and
case status information to Abt SRBI daily. This data will allow Field Managers to measure field
progress and implement strategies to meet the production goals. Field Managers will conduct
telephone verification on the first two completed households per interviewer. Thereafter we will
randomly select 10% of the sample for telephone validation
Close attention will be paid to the monitoring of panel attrition and ensuring that it is kept at a
minimum. The number of active respondents participating in each survey will be monitored on a
daily basis and proactive intervention will be implemented in consultation with the Stanford
investigators should the attrition rate increase beyond a set acceptable threshold.
