Exclusion Criteria

1) Physical illnesses that could seriously reduce their life expectancy or ability to participate in the trial

If the risk assessment states that they are at High” risk of harm to themselves, we would exclude the patient from the study. In addition, prior to recruitment, we will approach any potential participant’s care coordinators to verify the currently recorded risk, to ensure that the risk status has not changed.
