Abstract: Assessing levels of physical activity (PA) and providing feedback about these
levels might have an effect on participant’s PA behavior. This study discusses the effect of
different levels of feedback—from minimal to use of a feedback display and coach—on
PA over a 4-week intervention period. PA was measured at baseline, during and immediately
after the intervention. Participants (n = 227) were randomly assigned to a Minimal
Intervention Group (MIG-no feedback), Pedometer Group (PG-feedback on steps taken),
Display Group (DG-feedback on steps, minutes of moderate to vigorous physical activity
and energy expenditure) or Coaching Group (CoachG-same as DG with need-supportive
coaching). Two-way ANCOVA showed no significant Group × Time interaction effect for
the different PA variables between the MIG and PG. Also no differences emerged between
PG and DG. As hypothesized, CoachG had higher PA values throughout the intervention
compared with DG. Self-monitoring using a pedometer resulted in more steps compared with
a no-feedback condition at the start of the intervention. However, adding individualized
coaching seems necessary to increase the PA level until the end of the intervention.
