Ethical Considerations

A
  • Confidentiality
    • As some members of the delinquent group were involved violence and/or illegal activity, it would be important to keep their names confidential
  • Informed consent
    • Important that all partici[pants know the aim of the study before joining as it included discussing sensitive issues
