This research is concerned with investigating if phone interviews are as effective in gathering information for vetting purposes as face-to-face interviews.

Study Description

Participation in the research would require you to join one in-person testing session, in which you will be asked to participate in a role-playing exercise and a consequent vetting interview for “your friend John” for approximately 45 minutes of your time. Your interview will take place in the building and be conducted via phone or face-to-face and will be audio-recorded. If you are allocated to participate in the phone interviews, these will be conducted via Zoom but with audio only.

What will participants be doing?

You will be asked to participate in a role-playing exercise in which you will watch animations about “your friend John”. You will be interviewed about the content of the animations in a subsequent vetting interview in-person or via the phone. The animations describe your relationship with “your friend John” and involve topics such as gambling addiction, and drug use. If you do not feel comfortable talking about such topics, we kindly ask you to refrain from participating.


Approximately 45 minutes
