Guided Mastery Path · Orient
Step 1 of 10: Block orientation
This is your path progress — how far you've moved through the recommended sequence. It is not a measure of what you've actually mastered; see "Your mastery evidence" further down for that.
What F40-F48 covers, why it is organised the way it is, and how its 7 categories relate to one another.
This block groups seven otherwise quite different presentations — phobias, other anxiety disorders, obsessive-compulsive disorder, reactions to severe stress, dissociative disorders, somatoform disorders, and two remaining named neurotic disorders — that do not share one common four-character structure the way F10-F19's ten categories do, or one small set of shared axes the way F30-F39's seven categories do. Each category's own four-character subdivisions are organised around what is specific to it: a phobia's subtypes by trigger, OCD's by which of obsessions or compulsions predominates, a stress reaction's by the stressor's severity and timescale, a dissociative disorder's by which function is lost, and a somatoform disorder's by complaint pattern. What genuinely is shared across this block is a recurring reasoning pattern, taught category by category rather than in one shared table: distinguishing an ordinary, common human experience — fear, worry, a reaction to a stressful event, an unreality feeling, a bodily symptom, a lapse in memory — from the same experience crossing into a diagnosable disorder, always by checking disproportion or excessiveness, the specific duration this category requires, and genuine functional impairment, together with actively excluding a medical or substance cause.
