PURPOSE: To investigate the presence of reactivity, if any, to wearing sealed and unsealed pedometers, with and without step count recording. METHODS: On the first visit to the laboratory, 63 participants (41 females and 22 males; age = 23.6 +/- 9.6 yr, body mass index = 22.7 +/- 3.0 kg x m(-2)), blinded to the study aim, were provided with a sealed pedometer (New Lifestyles NL-1000) and informed that it was a "body posture monitor" (covert monitoring). Participants wore the pedometer throughout waking hours for 1 wk. On return to the laboratory, stored step counts were downloaded, and participants were informed that the device was a pedometer. Participants wore the pedometer under three more conditions-sealed, unsealed, and unsealed plus logging daily steps in an activity diary-each having a duration of 1 wk. The order of participation in each condition (sealed/unsealed/diary) was balanced across participants. Mean daily step counts recorded during the four conditions were compared using a repeated-measures ANOVA. RESULTS: There was a significant overall effect of condition (P {
