Analysis Psychometric analysis to assess how well individual survey items are performing Compare Spanish to English to assess whether Spanish version of instrument is performing like the English version Assess effectiveness of data collection modes Assess factors that may have affected variation in response rates across facilities

How will field test results be used? Revise instruments Improve translation Make recommendations for data collection approach that should be used Make recommendations for improving response rates Make recommendations for how data can be used
