Investigational drug(s) / intervention(s)
questionnaire
questionnaire: Questionnaires and interviews were primarily used as assessment and introspection tools to collect data on study participants' experiences, perceptions, and behaviors. Their purpose was to facilitate measurement and reflection rather than to deliver an intervention. However, it is acknowledged that participation in questionnaires and interviews may have had unintended interventional effects. Specifically, the process of answering questions and reflecting on personal experiences can increase participants' self-awareness, prompt critical reflection, and potentially influence subsequent attitudes or behaviors.
