Driven to Adapt: An Application of Adaptive Design with Multiple Low-productivity Telephone Samples
AAPOR Annual Conference – Anaheim, CA – May 15, 2014Adaptations
As the study progressed, we had to adapt:• Sampling methods and screening criteria
• More use of surname lists• More specific ethnic screening• Tighter geographic targeting
• Calling lab management• Don’t use all stations at once• Better feedback to interviewers• Outsource for better time zone and language
capabilities• Programming
• New screener logic facilitates changes• Production monitoring
• Change from overlapping counts to mutually exclusive categories
• New ways to acquire paradata from CATI system
• Used paradata to manage 30+ studies

Result: A Unique Dataset
Census tract and ZIP code data from 2010 ACS were used to determine if each group was sufficiently concentrated for geographic targeting. Lorenz curves represent incidence and coverage graphically.

The StudyThe National Asset Scorecard for Communities of Color [NASCC] is a detailed telephone survey designed to better understand the asset and debt positions of various ethnic and racial groups whose wealth status is often overlooked or inadequately measured.

This group was not concentrated enough to target geographically.
Selecting these ZIP codes should yield 50% incidence and include 80% of all blacks in DC.
