Bush-Francis Catatonia Rating Scale

Bush-Francis

Sum Bush 1996 23-item catatonia rating scale points from caller-assigned integers and report the 14-item screen (positive iff at least two of items 1-14 score above 0). Does not diagnose catatonia.

Not a medical device. Not a diagnosis, dose, or listing recommendation.

What it computes

Sum Bush 1996 23-item catatonia rating scale points from caller-assigned integers and report the 14-item screen (positive iff at least two of items 1-14 score above 0). Does not diagnose catatonia.

When to use

When an agent already has Bush 1996 23-item integers and needs the published severity sum and 14-item screen. magent does not perform the standardized examination, diagnose catatonia, or apply DSM catatonia criteria.

When not to use

• Not a medical device and not a diagnosis of catatonia or a treatment order.
• Each of the 23 items is a caller-assigned Bush 1996 integer. magent does not perform the standardized examination and does not examine the patient.
• Screening uses the first 14 items only: screen_positive is true iff at least two of those items score above 0 (Bush 1996 cases defined by ≥2 signs on the 14-item screen). This is not DSM catatonia criteria as a separate tool.
• Items 17-21 (mitgehen, gegenhalten, ambitendency, grasp_reflex, perseveration) are 0 or 3 only in Bush 1996. magent does not apply later training-manual changes to those ranges.

Formula

Bush-Francis CRS = excitement + immobility_stupor + mutism + staring + posturing_catalepsy + grimacing + echopraxia_echolalia + stereotypy + mannerisms + verbigeration + rigidity + negativism + waxy_flexibility + withdrawal + impulsivity + automatic_obedience + mitgehen + gegenhalten + ambitendency + grasp_reflex + perseveration + combativeness + autonomic_abnormality; Bush 1996 23-item catatonia rating scale; items 1-16 and 22-23 integers 0-3; items 17-21 (mitgehen, gegenhalten, ambitendency, grasp_reflex, perseveration) 0 or 3 only; severity score = sum of items 1-23; screening instrument = first 14 items; screen_positive iff count of items 1-14 with score > 0 is >= 2; max 69; not a diagnosis

Call

Expect HTTP 402 until you retry with PAYMENT-SIGNATURE. Incomplete query params return HTTP 400 before any quote or charge.

curl -i -H "Accept: application/json" "https://api.magentlab.com/api/calc/bush_francis?excitement=1&immobility_stupor=1&mutism=0&staring=0&posturing_catalepsy=0&grimacing=0&echopraxia_echolalia=0&stereotypy=0&mannerisms=0&verbigeration=0&rigidity=0&negativism=0&waxy_flexibility=0&withdrawal=0&impulsivity=0&automatic_obedience=0&mitgehen=0&gegenhalten=0&ambitendency=0&grasp_reflex=0&perseveration=0&combativeness=0&autonomic_abnormality=0"

Parameters

Bulk (POST)

POST the same path with a JSON items array. The first item is the GET unit; each additional item is $0.002. Invalid items return HTTP 400 before settlement.

POST /api/calc/bush_francis Max 25 unit_amount + extra_item_amount * (n - 1) extra $0.002 PREVIEW

• 1 to 25 items. Each item uses the same keys as the GET query parameters.
• POST of 1 item costs the same as GET. Lists longer than 25: chunk into multiple POSTs. Extra items still execute; do not pad dummy rows.
• The first invalid item fails the whole request (index in the 400 JSON). You are not charged.
• HTTP 200 is {count, path, items}. Each items[i] is the GET 200 body for that row.
• Catalog misses (empty matches, found=false) stay paid 200s inside that slot.
• x402 resource URL is this path plus n and body_sha256. Browsers that prefer text/html get the same paywall as GET; Pay retries POST with the same items.

Client errors (HTTP 400)

Invalid params return 400 without charge. Shared HTTP 402 and 503 meanings: Payments.

• BARS — Return the Swift 2002 Behavioural Activity Rating Scale (BARS) 1-7 from a caller-assigned integer, with a stable label.
• GDS-15 — Sum fifteen Sheikh 1986 GDS-15 yes/no items using that paper's reverse-scoring key and return the published 0-15 total. Does not apply later total-score severity bands.
• RASS — Return the Sessler 2002 Richmond Agitation-Sedation Scale term and description from a caller-assigned integer -5 to +4.

Payment

Unpaid requests return HTTP 402 even if query parameters or POST items are missing or invalid, so CDP and agents can index the path. After a PAYMENT-SIGNATURE, invalid params return HTTP 400 JSON before settlement. magent does not charge. Fix the params, then request a new 402 quote for that complete URL. Catalog misses (empty matches, found=false) are valid paid 200s. Unpaid valid requests return HTTP 402 with a base64 PAYMENT-REQUIRED header. HTTP 503 is not a new quote: retry the same PAYMENT-SIGNATURE. Full handshake and shared payment errors: Payments. Stdio MCP: /docs/mcp.

Guarantees

• HTTP 402 is unpaid, including a missing query. After PAYMENT-SIGNATURE, invalid parameters return HTTP 400 before settlement. You are not charged. HTTP 402 never includes the tool JSON.
• exact: settlement finishes before the tool (paymentFlow upfront). batch-settlement: verify/deposit before the tool; chargedCumulativeAmount commits after HTTP 2xx. Uncertain or failed settlement fails closed (HTTP 503). Retry the same PAYMENT-SIGNATURE.
• HTTP 402 is unpaid only. Do not sign a second authorization because of a 503.
• Execution is timeout-bounded and concurrency-capped.
• Calculator inputs are stored encrypted for allowlisted operators (Magent Console). They are not in public logs, SSH lookups, catalog, or rollups. Request logs store path without query.
