To ensure trustworthiness:

• Use triangulation: Compare your findings with other data sources (e.g., school reports or policy documents).
• Have a second coder review your codes and themes.
• Conduct member checking: Share your findings with the interviewees to confirm accuracy.
• Keep a transparent audit trail of how you developed the themes. For instance, document why you grouped certain codes under "Parental Engagement in Health Promotion."
