We evaluated compliance with submitting a short Web-based personal behavior survey daily during a 10-week study (n = 52 women/3419 diaries). Time-stamped forms revealed that 50% of diaries were submitted within 24 hours of the email prompt, and 19% were missing or submitted more than 3 days late. Late submissions may affect data quality.

SummaryIn a longitudinal study requesting daily online completion of short personal behavior diaries, 19% of surveys were missing or submitted over 3 days late. Delayed submissions may indicate recall bias.
