Consider Option A: Pre-post interviews asking open-ended questions about motivation and experiences

  • Pre-post interviews with open-ended questions provide the most comprehensive understanding because they allow participants to express complex changes in motivation in their own words.
  • Interviews can capture unexpected factors, personal insights, and detailed explanations about how and why motivation changed throughout the program, providing rich qualitative data that other methods cannot capture.

Other Options:

  • B is incorrect: Only captures external behaviors (attendance, effort) which may be influenced by factors other than motivation.
  • C is incorrect: Doesn’t measure changes in motivation since it only collects data at one time point.
  • D is incorrect: Measures physiological response to exercise, not psychological factors like motivation.
