The following quote answers my question:<BR/><BR/>(begin quotes)<BR/><BR/>It was assumed, and later confirmed by the hotel housekeeping managers, that the workload of the room attendants remained constant in the 30 days prior to and the 30 days during the study. Therefore, if there was no increase in reported exercise outside of work, any increase in perceived regular exercise, perceived amount of exercise, or perceived work as exercise would be assumed to reflect a change in mind-set initiated by the intervention and not due to an increase in actual exercise.<BR/><BR/>Also: <BR/><BR/>They were given specific details of the average calorie expenditure for various activities (changing linens for 15 min burns 40 calories, vacuuming for 15 min burns 50 calories, and cleaning bathrooms for 15 min burns 60 calories), and they were told that although these figures were based on results for a 140-pound woman and each of them would burn calories at a different rate, it was clear that they were easily meeting and even exceeding the Surgeon General’s recommendations. 2 This sheet, written in both English and Spanish, was read and explained to the subjects and then posted on the bulletin board in their lounge.3<BR/><BR/>And finally:<BR/><BR/>Of course, it is possible that the room attendants actually did change their behavior—actually did cut back on calories, improve the quality of the food they ate, or work harder or more energetically—but did not report such changes.8 However, previous research has found it very difficult to change behavior of this sort (Deutschman, 2005). Thus, even if these behavioral changes did occur as a result of the intervention, that too would make these results interesting.<BR/><BR/>(end quotes)<BR/><BR/>These workers ate their lunch every day staring at a big poster extolling the physical benefits of their daily routine. It is easy to believe that this could have induced them to make beds or scrub bathrooms a little more vigorously, which would certainly have a nontrivial cumulative effect over the course of 20 8-hour days. <BR/><BR/>The placebo effect need not be some sort of magic mind-over-matter to be effective. One can similarly imagine that the effect of placebos on pain perception is as much due to subjects actively managing the focus of their attention as anything else. Placebo stimulants could similarly operate through conscious control of attention. <BR/><BR/>Of course, this is just rampant speculation on my part, but I'm just posting it as a comment in a blog, rather than trying to publish it in a peer-reviewed journal.Mean 3Monkeyhttps://www.blogger.com/profile/08043494488087761724noreply@blogger.comtag:blogger.com,1999:blog-22093933.post-12756818509317996422007-09-14T14:47:00.000-05:002007-09-14T14:47:00.000-05:00You make a very good point.

I could easily imagine that the "informed" group, having been provided with examples of how their jobs contain elements promoting physical fitness, then spent more time and energy on those aspects of their jobs. That is, the "placebo" information could easily have altered their behavior in subtle but significant ways. It is worth noting that the data necessary to measure such a behavioral change would be extremely difficult to acquire. Unfortunately, my institution does not have a subscription to the journal, so I can't verify this myself, but the claim is weak without such a control.Mean 3Monkeyhttps://www.blogger.com/profile/08043494488087761724noreply@blogger.com
