- Hiya,
- Since a couple of people have requested to see the original posting
- that started this bathroom/ethics discussion, here it is again.
- Tis interesting that my original concern (Subj: Validity of self
- report data) hasn't been the major focus of discussion. :)

- Hiya,
- We collected some interesting data last semester when I was teaching
- an experimental psych lab. We found large discrepancies between self
- report and observational data in handwashing behavior in public
- restrooms. The students in the experimental psych class either
- hid out of sight in the restroom or were in sight the
- sink area and noted whether ppl washed their hands after using the
- restroom or not. We found in this behavioral observation portion
- of the study that females are more likely to wash when others are
- present, the effect for males was nonsignificant tho was in the
- same direction. Then we administered a public facilities
- questionnaire to a convenience sample with two questions embedded
- 1) did you wash, 2) were there people present. In this self report
- data, we didn't find the social norm handwashing effect. Using the
- behavioral observation data as an estimate of how frequently
- people usually wash their hands, we found that people overreported
- hand washing on the questionnaire. From the behvioral data,
- about 50% of people washed their hands. However in the self report
- data 67% of males and 88% of females said they washed their hands.
- I kinda think this is a social desirability bias... However
- it could also be a result of errors in memory, or using two different
- samples, or even demand characteristics of the public facilities
- questionnaire. This semester I'll have my lab pretest the questionnaire
- to check for demand characteristics and we'll administer it to the *same*
- people that we collect observational data on, to rule out memory and
- sampling. If indeed we do find the same over reporting of handwashing
- behavior then It'd be nice to be able to be able to administer
- questionnaires to find out if it's related to self deception/other
- deception or some social desirability measure. I might even include
- self monitoring. Does anyone have such scales on disk and references
- for them, that they could e-mail me? This is a new area of research for
- me. Also ideas for other measures which might explain why this
- is happenin would be appreciated.
-
- Anyone have any comments or ideas about this project? It worries
- me that we found such a large discrepancy between self report and
- observational data, since a large portion of the data in psychology
- is self report in nature. What other behaviors could we *both*
- observe and ask for self report on that vary in social desirability
- pressures? Replication of this paradigm in different behaviorl
- domains should allow us to get a better idea of just when we can
- and can't get accurate estimates of behavior from self report data.
