Limitations
RECRUITMENT
This study’s participant pool on crowdsourcing did not reflect older adults, who have the highest risk for medication harm [Due to the novelty of our method and the lack of literature support for this specific approach, we did not perform a power calculation for this study. However, we acknowledge that this is a limitation and may have impacted the precision of our estimates and our ability to detect small effects. Instead of conducting a power analysis, we opted to increase our sample size as needed, considering the relatively low cost of our sample.Crowdsourcing incentives study participants to complete the study as quickly as possible, although the use of multiple items and reverse-coded questions reduced this risk. The recruitment process relied on study participant self-selection, and thus selection bias was not assessed.The simulated responses in the study may be different from the actual responses in real health care encounters. MTurk users may choose to respond as fast as possible. We instituted measures to counter this risk, such as using reverse-coded questions to screen for noninvestment and filtering patterned responses.
