While I agree personally that extended computer use prior to going to bed tends to make getting to sleep more difficult. I also observe that few researchers - psychologist or otherwise are trained in making professional grade unbiased surveys and that surveys will never replace the hard science of well designed and statistically significant clinical studies. Lately medical research has been plagued with lots of poorly designed, very lose meta-analyses, and as well highly subjective surveys - possibly like this one - that are really questionable in the significance of their results.
It's quite easy to examine blood melatonin levels in an experiment consisting of various periods of computer use before a set bed time, recording the time it takes to get to sleep, versus non-computer users under the same situation. Then wait a month and using the same participants reverse experimental situation on the experiments' participants (non-computer users are now the users and vice-verse) and compare the results. Typically survey's are medically one step above hearsay - obviously more than sufficient for today's level of journalism, but woefully unreliable scientifically.
