Brief summary
The main study aimed to explore men's reasons for transitioning from active surveillance to further treatment in prostate cancer management, and the factors which may have contributed to this decision. In this study within a trial, we investigated whether response rates to the questionnaire would differ by incentive amount (provided as an unconditional monetary incentive in the form of a gift card). All participants were required to complete a one-time survey (sent via mail but may be completed on paper, online, or via telephone). This survey consists of questions relating to social-ecological factors (i.e., personal, social, community, organisation, policy) and your experience with active surveillance. Participants in the main study were randomised to receive either a $20AUD or $10AUD unconditional incentive with their study materials. We aimed to investigate whether (a) response rates to a 30-minute questionnaire completed via mail, online, or phone would vary with different unconditional incentive amounts, and (b) demographics would vary in those who responded within the different incentive groups.
Interventions
We conducted a randomised study within a trial (SWAT) in a case-control cross-sectional study aiming to explore the social-ecological reasons why prostate cancer patients discontinued active surveillance. All participants were recruited through the South Australian Prostate Cancer Clinical Outcomes Collaborative (SA-PCCOC). Participants in the main study were to complete a survey that took approximately 20-30 minutes to complete. Prior to the mail-out, a pilot test (N=32 controls) was conducted
We conducted a randomised study within a trial (SWAT) in a case-control cross-sectional study aiming to explore the social-ecological reasons why prostate cancer patients discontinued active surveillance. All participants were recruited through the South Australian Prostate Cancer Clinical Outcomes Collaborative (SA-PCCOC). Participants in the main study were to complete a survey that took approximately 20-30 minutes to complete. Prior to the mail-out, a pilot test (N=32 controls) was conducted to assess the probable response rate. Six of the 32 responded (19% response rate). Therefore, alterations to the materials and protocol were made in an attempt to boost the response rate. We reduced the survey length (by two pages, reducing time to complete to ~ 20 minutes), sent all participants a priming letter two weeks prior to study materials, and included an unconditional incentive. Participants were randomised to receive either an AUD$10 or AUD$20 unconditional gift card (redeemable at thousands of Australian stores) incentive with the study materials. In this SWAT, we aimed to investigate if (a) response rate would vary by different relatively large unconditional incentive amounts, and (b) patient characteristics (e.g., age, marital status, employment status, education level) would vary in those who responded within the different incentive groups. Intervention group: Recieved a $20 unconditional monetary incentive with their study materials.
