Do personalised e-mail invitations increase the response rates of breast cancer survivors invited to participate in a web-based behaviour change intervention? A quasi-randomised 2-arm controlled trial

Published: 19 August 2015BACKGROUND: Previous research has shown that the personalisation of study invitations improves response rates in survey-based research. To examine if this finding extends to experimental studies, we examined the impact of personalised study invitation e-mails on the response rates of potentially eligible breast cancer survivors for participation in a 6 month randomised controlled trial testing the efficacy of a physical activity intervention. METHODS: Potential participants (n = 344) were sent either a personalised email or a generic email. RESULTS: Those sent the personalised email were 1.5 times (95 % CI = 1.18-1.93) more likely to respond than those sent the generic email. CONCLUSION: These findings suggest that personalisation may be a useful and potentially powerful tool that can be utilised when recruiting participants into experimental studies in order to boost response rates.Camille E.
