title: Effect of certified personal trainer services on stage of exercise behavior and exercise mediators in female college students.
abstract: OBJECTIVE
  The authors examined the effect of certified personal trainer services on exercise behavior by using the transtheoretical model of behavioral change.
  
  
  METHODS
  Female college students (n = 449) completed surveys during the first week (T1) and last week (T2) of the fall semester.
  
  
  METHODS
  Students receiving personal trainer services during the fall semester (experimental group, n = 31) were cross-matched with students who had not received services (control group, n = 31).
  
  
  RESULTS
  The control group demonstrated a statistically significant regression in stage of exercise change scores; the experimental group did not. The authors found the 2 groups to have a statistically significant difference in the pattern of exercise behavior change over the course of the semester, with more active maintainers and progressors in the experimental group.
  
  
  CONCLUSIONS
  Cognitive and behavioral processes of change, decisional balance, and scheduling self-efficacy significantly decreased in the control group, whereas cognitive processes of change, decisional balance, and scheduling self-efficacy remained statistically unchanged in the experimental group.
