The structure that gets read
Page-one psychoeducation that clients actually use follows a five-block layout: (1) a one-sentence validation of the experience ('Panic attacks feel like dying — that is the body's alarm doing its job badly, not a sign of real danger'); (2) one model or metaphor ('the smoke detector triggered by burnt toast'); (3) what the science says, in two sentences, no citations; (4) three small actions for the week; (5) one line about when to escalate or call. If the handout is longer than one page, it is a workbook, not psychoeducation.
Why metaphors outperform mechanism diagrams
Diagrams of the amygdala, HPA axis, or default mode network feel rigorous but produce worse recall and behavior change than a single sticky metaphor. The brain encodes images and stories more durably than schematics. The leaf on the stream (defusion), the smoke detector (anxiety), the wave (urges), the unwelcome party guest (intrusive thoughts), the team meeting (parts work) — these earn their longevity because they are portable. A client can remember a metaphor in the parking lot of Trader Joe's; they cannot remember a polyvagal diagram.
Reading level, fonts, and accessibility
Aim for 7th–9th grade reading level (use the Hemingway Editor or Flesch-Kincaid). Sans-serif body type at 11–12 pt, headings 14–16 pt, line height 1.4. Left-align text — do not justify, which breaks for clients with dyslexia. Avoid italics for long passages. Provide a high-contrast version (dark text on cream, not pure white) for clients with visual sensitivity. If the handout is to be printed in a clinic with a black-and-white copier, design without color reliance.
