The same-day registration ballots are subject to the standard Ohio notification card protocol whereby a postcard is sent to the newly registered address to assist in determining the validity of the address.
Here is helpful analogy: Sending a communication (an email or web page or video file or whatever) via Internet Protocol packets is like sending a book by postcard.
The baseline survey mailing follows a modified Dillman protocol to maximize response rates and data quality (mail + postcard reminder + mail + mail) [ 14].
Although the per-protocol analysis showed a strong benefit for the crisis postcard, the primary finding of the present study was that the crisis postcard intervention did not significantly reduce subsequent suicidal behaviour in the intention-to-treat analysis.
The ITT analysis showed no effect for the crisis postcard (hazard ratio = 0.84; 95% CI = 0.56 – 1.29), but the per-protocol analysis showed a strong benefit for the crisis postcard (hazard ratio = 0.39; 95% CI = 0.21 – 0.21).
The protocol followed a modified Dillman approach [ 22] involving a pre-notice postcard (day 1), a mailed questionnaire (day 4), a thank you/reminder postcard (day 11), and a second questionnaire mailing (day 24) to remaining non-respondents.
The intention-to-treat analysis indicated that the crisis postcard had no effect (hazard ratio = 0.84; 95% CI = 0.56 – 1.29), whereas the per-protocol analysis showed a strong benefit for the crisis postcard (hazard ratio = 0.39; 95% CI = 0.21 – 0.21).
Figuratively speaking, the Internet Protocol allows your computer to take your book, cut out the pages, and glue each page onto a postcard.
