研究问题
However, innovation also occurs more incrementally through the refinement of research methods and the expansion of populations included in empirical inquiry.；As factorial surveys have been increasingly applied to aging populations, methodological discussions have begun to address key challenges associated with their use.；However, this relationship remains conceptually and empirically ambiguous.
方法
First, they enable the elicitation of older adults’ own preferences and evaluative criteria, thereby supporting more person-centred and preference-based evidence for policy and practice ().；Second, they allow the study of sensitive or rare situations, such as end-of-life decisions, relocation, or family support, without exposing participants to real-world risks, enhancing both ethical and practical feasibility (; ; ).；To our knowledge, one of the earliest studies explicitly involving respondents aged 60 and older examined health information–seeking behavior using a factorial survey design ().；Participants were recruited between 2018 and 2023 through the interviewers’ extended personal networks, including local community members and informal senior networks.
核心结论
At the descriptive level, age was positively associated with response time (r = 0.31, p < .001), indicating that older participants tended to take more time to complete the vignette task.；Multivariate regression models focusing on response inconsistency revealed no systematic differences between participants aged 60–69 or 70–79 and the reference group (50–59).；Only respondents in the oldest age group (80–99) showed higher average residual variation across vignette ratings (β = .23, p < .05). ‖ 结论：These findings underscore the importance of analytically separating response pace from response consistency and avoiding the use of observable characteristics, such as age or response time, as indirect indicators of data quality.
局限
Only in the highest age group did the residual-based inconsistency index indicate higher unexplained variation in vignette evaluations.；These findings should be interpreted with caution, given the limited number of observations at longer response times and the absence of statistically significant interaction effects.；However, they indicate that the relationship between response pace and response consistency may not be uniform across the full range of response times.
