Appendix G — Survey Instrument

The questionnaire below is the gold-standard household survey instrument fielded for this study. Programmatic differences across collection methods (e.g., Lot Quality Assurance Sampling (LQAS) ran one continuous form per Enumeration Area (EA), while the gold-standard assigned individual households and opened a separate form instance per household) were not respondent-facing, so a single instrument is reproduced here.

This annex reproduces the gold-standard household survey instrument used during data collection. Calculated, sensor, and device-metadata fields are omitted; only respondent-facing questions, notes, and group/repeat structure are shown. Personally identifiable information from the field-team rosters has been redacted.

The instrument is split by section. Within each section, the Variable column gives the field name, Question the text shown to (or read aloud for) the respondent (with any enumerator hint below), Response the type and inline choice list, and Asked when the skip-pattern expression that determines whether the question is shown.
