Answer:
1) This situation is out of the standard set by Tarasoff decision’s duty to protect because the situation is severe and Dr. Yeung should not rely on probability. This could be possible that Aiden was trying to threaten Dr. Yeung and demanding no interference in his personal life. Dr. Yeung is a health psychologist but as a psychologist, she could understand the seriousness of the situation so she must call the professional support. Dr. Yeung should refer this case to the clinical psychologist and provide support to them about the health and behavior conditions.
2) Ethically, Dr. Yeung’s decision may affect the research purpose but morally her decision may help a person who needs it. The decision of Dr. Yeung was exceptional so it must be considered as an exceptional condition.
3) Dr. Yeung should consult the clinical psychologist and psychiatrists before handling this type of case. Dr. Yeung was not assigned to handle abnormal behavior problems and therapies, she could have handled the situation as an exceptional condition and with the help of team support.
4) Dr. Yeung should consider this case as health and abnormal behavior problem rather than a general condition. The behavior of Aiden was destructive and it should be analyzed with the help of security agencies, medical practitioner, psychologist and psychiatric. Dr. Yeung tried to done her job well but her lack of experience could have threaten her and patient’s life. I think, Dr. Yeung should demand professional help and experienced services.
