I have to seriously question the accuracy of this study. I'm an obstetrician (cesarean surgeon) and I have never noticed texting to have a positive effect on my patients. From my observations, it seems to cause them a lot of stress (and thus increases the pain) and it almost certainly increases the duration of the procedure (because I'm busy texting and am just sort of jimmying the scalpel around with my other hand).
I had typed out a long reply explaining potential differences between your experience and the results of the study... then I reread your final parenthetical statement...
