For my interviews, I used these questions as a guideline:
1. What is the hardest part about completing your assignments?
2. Tell me about a time you felt stressed or anxious towards your schoolwork and/or deadlines.
3. Why did that particular situation seem stressful?
4. What have you done in the past to try and not feel stress or anxiety towards school?
5. Have those solutions helped? If not, why did it not help?
They varied between interviews as I wanted more of a conversation with my interviewees. I believe people will open up and give more meaningful answers when they feel like they are just having a conversation as opposed to being questioned.
