A note on this workbook
This workbook only covers:
• What the disorder is (definition)
• How long symptoms must occur for to meet diagnosis
• The named types / sub-categories specified in the syllabus
• The symptoms attached to each diagnosis
Explanations and treatments are separate sub-topics and are intentionally not
included here, so you can focus purely on mastering diagnostic criteria first.
Explanations and treatments are a separate workbook.
A note on ICD-11
Diagnostic:
CIE 9990 specifies that, for assessment purposes, the terms used are those of
the ICD-11 (International Classification of Diseases, 11th revision), while
accepting alternative terminology (e.g. DSM-5) if used appropriately. This pack
uses ICD-11 terminology and structure throughout, matching what you'll see in
your exam.
I recommend using the blank ICD worksheet pages (pg 8) after your familiar with definitions or
read definition pages, Writing criteria out from memory and then checking against the definition
pages - this is more effective then re-reading or checking it allows memory to be strengthened.
