EAT-26 (Garner 1982) — 26 items, validated eating disorder screen. EDE-Q (Fairburn & Beglin 1994) — in-depth DSM-5 assessment. Lifetime prevalence of any ED in women: 8.4% (Galmiche 2019). What an EAT-26 cut-off of ≥20 indicates, where screening ends and clinical diagnosis begins, and why BED is the most common ED.

Types of supervision (individual, group, peer), what belongs in the contract, frequency, how to evaluate supervisor competence. MBC frame: supervision + client outcome data = more accurate feedback than "let me describe the case from memory". Evidence: Shimokawa, Lambert & Smart 2010 — feedback in supervision doubles the recovery chance for clients on a worsening trajectory.

BHS — 20 true/false items, developed by Beck in 1974 as a predictor of long-term suicide risk. In an inpatient sample (Beck et al. 1985), a cut-off of ≥10 correctly identified 91% of those who later died by suicide. What the scale measures, how to read the thresholds, and how BHS differs from current suicidal ideation (C-SSRS).

The WHO ASRS-v1.1 is the most widely validated brief adult ADHD screen. What the 6-item short form actually shows, how to read the full 18 items, and why screening is not a diagnosis. DIVA-5, CAARS and WURS for confirmation.

A guide to validated trauma and PTSD screening instruments: PCL-5 (DSM-5), ITQ (ICD-11 PTSD and CPTSD), IES-R (response dynamics), LEC-5 (event inventory), CAPS-5 (clinician-administered gold standard). Why a "trauma test" is not a diagnosis and how to assemble a battery for the clinical task.

ECR-R, AAS, RSQ — validated instruments produce a 2D profile (anxiety × avoidance), not one of "four types". What a clinical attachment test actually shows, and how it differs from popular online quizzes.
