The collection consists of working papers relating to Buchanan's professional career as a forensic psychiatrist in the UK, [1984]-2001, chiefly research papers relating to the Special Hospitals Service Authority and psychiatric reports relating to Maudsley Hospital patients. Section 1 comprises papers arising from the daily administrative operations of Maudsley Hospital London. Section 2 contains research notes, questionnaires and criminal record 'multiple enquiry forms' produced from the Home Office Offenders Index. This material relates to an unpublished study conducted by Buchanan, 1992-1995, of discharged special hospital patients convicted of violent re-offences. The findings, intended to inform the decision making of those entrusted with the care of special hospital patients, were funded by the Special Hospitals Service Authority. There are also confidential psychiatric reports (see ref 3/1 to 3/6), produced by forensic psychiatrists at Maudsley Hospital, London. The reports evaluate an individual's competency to stand trial, defences based on mental diseases or defects (for instance the "insanity" defence), and sentencing recommendations. Section 4 contains questionnaires relating to a project funded by the John D and Catherine T MacArthur Foundation focused on developing the Maudsley Assessment of Delusions Schedule to provide a more accurate and effective way of assessing patient's delusions. Section 5 consists of papers relating a psychiatric case assessed by Buchanan in his capacity as a member of the Serious Untoward Incident Panel of the Hounslow and Spelthorne Community and Mental Health NHS Trust. The collection also includes photocopies of articles from medical publications and on-line resources compiled by Buchanan which relate to the ethical connotations of patient confidentiality in connection with medical trials and research (see ref 6/1).
