I'm asking this because CDC in the Limitations section of NISVS 2015 and NISVS 2016/17 surveys said that:

NISVS 2015

Fourth, self-report data are vulnerable to recall bias and telescoping, in which respondents report incidents as having occurred closer in time than they actually did; such bias might affect 12-month estimates especially. However, allowing the respondent to report their lifetime victimization is likely to reduce the potential for telescoping.

NISVS 2016/17

recall bias and telescoping, which is when respondents remember incidents as having occurred more recently than they did in reality. Telescoping may have affected the past 12-month estimates in particular.

https://www.cdc.gov/nisvs/documentation/nisvsReportonSexualViolence.pdf

In the 2016/17 survey, they cite a paper in which the author uses just one high-school study to say that 1 month data, 6 month data and 12 month data is subject to telescoping bias.

Wiki says that

If a question clearly defines the time period of interest, telescoping errors will be reduced.

I found one more study regarding this which found that a small backward telescoping effect for recent news events and a large forward telescoping effect for remote events.

Another study found that the magnitude of the forward telescoping bias increased, whereas the likelihood of making backward telescoping errors decreased with the time. It also found that the tendency to make forward telescoping errors was greater for men than for women and for younger and older adults relative to middle-age adults.

I dont know what to make of this and I also don't know much about this topic.

Can anybody who knows more about this enlighten me regarding this? Do these studies agree with CDC's assertions or do they contradict it?
