Description

Dear US Support Team,

I am analysing the US youth self-completion questionnaire for waves 1-7. I have been plotting the histograms for distributions of NETCHT each year. There seems to be a spike in youth reporting they use no social media (option 1) in 2011. Normally there are ~200 respondents choosing 1, but in 2011 there are ~700. There seems to have been no change in the question, or phrasing, so I am not sure why this is occurring. I can provide my R code if that is helpful.

I have attached the histogram. I have also attached a histogram of the ages of the respondents choosing option 1 each year. It seems like many 10 years olds are choosing 1 in 2011.

I think this is a clear anomaly and dont want to proceed with my analyses without knowing why it is occurring.

Best wishes,
Amy

Dear Stephanie,

Thank you for the explanation you emailed me about this, I copy it into the bottom of this email just for your information. I have been looking at the data again, and have been finding anomalies which make it impossible for the solution you suggested to explain the occurrences (I think!).

Find attached a screenshot of a table I made examining people's responses for socweb and netcht. If you explanation would be true, then we would expect that for 2011 (year 3) more people who score 2 on socweb to choose 1 for netcht, but not a single participant has this sort of response pattern.

The only explanation I could give of this, is that you automatically code anyone who does not choose NA for netcht as a 1 for socweb. Could that be true?

Many thanks,
Amy

"We have investigated this issue and found that the response “none” to c_ypnetcht may have an increase in responses due to the routing from the previous question (c_ypsocweb) being on a separate page of the questionnaire in Wave 3, whereas in other waves w_ypsocweb appears on the same page. We think that some younger respondents who had less experience in answering our questionnaire may have forgotten about the routing and answered the question at the top after turning the page. If you combine the missing values in w_ypnetcht (they did not answer this question because they do not have a social media account) with the “none” response (they do not spend any time interacting with friends on social media) in each wave, the spike does not appear."
