Survey Methodologies in Health Research
Summary
Survey methodologies in health research encompass a range of approaches designed to collect data on populations’ health status, behaviours and service experiences. Traditional methods include postal questionnaires and telephone interviews, while emerging approaches employ web-based instruments, mobile applications or mixed‐mode designs combining digital and paper options. Key considerations in survey design involve defining an appropriate sampling frame, optimising question wording and length, and selecting modes that balance cost, coverage and data quality. Response rates have been declining globally, prompting greater attention to non-response bias, representativeness and the use of reminders or incentives. Reporting standards and checklists have been developed to improve transparency around instrument validity, handling of missing data and sample characteristics. Technological advances such as secure online mailboxes or social-media recruitment offer new opportunities, yet they also raise issues of digital exclusion, measurement error and survey fatigue. Overall, robust survey methodology underpins reliable health estimates, informs policy decisions and supports monitoring of public-health interventions across diverse settings.

The graph below shows the total number of articles in survey methodologies in health research across all publications each year (not limited to Nature Index journals).
Technical terms
Web-based questionnaire: An online survey delivered through secure digital platforms, accessible via computers or mobile devices.
Response rate: The percentage of invited individuals who complete and return a survey instrument.
Non-response bias: A distortion that occurs when individuals who do not participate differ systematically from respondents.
Sampling frame: The list or database from which potential survey participants are drawn, intended to represent the target population.
Survey fatigue: A decline in willingness to participate or in response quality resulting from repeated or lengthy survey invitations.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
