Improving survey response rates from parents in school-based research using a multi-level approach

Area of Science:

• Public Health
• Epidemiology
• Child Development Studies

Background:

• School-based recruitment is vital for community studies but faces challenges.
• Multi-level engagement strategies are recommended but their impact is under-documented.
• This study compares standard versus enhanced engagement for recruitment indicators.

Purpose of the Study:

• To compare the effectiveness of standard versus enhanced school engagement on recruitment metrics.
• To evaluate the impact on parent response rates, consent, and follow-up.
• To assess the influence on response times and number of reminders needed.

Main Methods:

• Two cohorts (2011, 2012) were recruited using a screening questionnaire.
• Cohort 2 received enhanced engagement: pre-notification postcards, improved materials, and progress graphs.
• Chi-square and t-tests analyzed differences between cohorts.

Main Results:

• Cohort 2 showed higher parent response (76% vs 69%), consent (71% vs 56%), and follow-up agreement (91% vs 80%).
• Fewer reminders were needed for cohort 2 (52% vs 63%).
• Cohort 2 parents responded significantly faster (19.4 days sooner).

Conclusions:

• Investing in enhanced multi-level engagement strategies is valuable.
• These strategies maximize parent response rates in school-based studies.
• Enhanced engagement can reduce recruitment time and associated costs.
