# Adult ADHD Self-Report Scale (ASRS) ASRS Status: LIVE Price: $0.005 USDC `GET /api/calc/asrs` HTML: https://magentlab.com/docs/asrs Markdown: https://magentlab.com/docs/asrs.md Not a medical device. Not a diagnosis, dose, or listing recommendation. ## What it computes Count Kessler 2005 clinically significant ASRS v1.1 Part A items (six caller-assigned 0-4 frequencies) and return whether four or more are in the published range. ## When to use When an agent has already assigned Kessler 2005 0-4 integers for each of the six ASRS v1.1 Part A items and needs the published 4-of-6 screen, not an ADHD diagnosis or the 18-item ASRS. ## When not to use - Not a medical device and not an ADHD diagnosis or treatment order. - Each of the six Part A items is a caller-assigned integer 0-4 (0 never, 1 rarely, 2 sometimes, 3 often, 4 very often). magent does not interpret the items and does not interview the patient. - This is Kessler 2005 ASRS v1.1 6-item screener (Part A) only. magent does not score the 18-item ASRS or later 0-24 sum cutoffs. - wrap_up, organization, and remembering are clinically significant at sometimes or more (≥2). avoid_delay, fidget, and motor are clinically significant at often or more (≥3) (Kessler 2005 Table 1 footnotes). Screen-positive at ≥4 of 6 (Table 4 highest stratum). It is a screen, not a diagnosis. ## Formula ``` ASRS Part A = count of Kessler 2005 clinically significant items among wrap_up, organization, remembering, avoid_delay, fidget, motor; wrap_up/organization/remembering ≥2 (sometimes); avoid_delay/fidget/motor ≥3 (often); screen-positive at ≥4; max 6 ``` ## Citation [The World Health Organization Adult ADHD Self-Report Scale (ASRS): a short screening scale for use in the general population](https://doi.org/10.1017/s0033291704002892) Kessler RC, Adler L, Ames M, et al. Psychol Med. 2005;35(2):245-256 DOI: [10.1017/s0033291704002892](https://doi.org/10.1017/s0033291704002892) ## Worked example ### All items never Given: `avoid_delay=0, fidget=0, motor=0, organization=0, remembering=0, wrap_up=0` 1. wrap_up 0, organization 0, remembering 0, avoid_delay 0, fidget 0, motor 0: none clinically significant 2. Score = 0 (max 6); screen_positive false (threshold is ≥4) ### Four clinically significant items at published floors Given: `avoid_delay=3, fidget=0, motor=0, organization=2, remembering=2, wrap_up=2` 1. wrap_up 2, organization 2, and remembering 2 count (≥ sometimes); avoid_delay 3 counts (≥ often); fidget 0 and motor 0 do not 2. Score = 4; screen_positive true ## Also searched as - Adult ADHD Self-Report Scale - ASRS v1.1 - ASRS Part A - Kessler ASRS - 6-item ADHD screener - ASRS 6-question screener - adult ADHD screening scale - ASRS score ## Parameters - `wrap_up` (integer, required): Caller-assigned Kessler 2005 ASRS v1.1 Part A item 1 (integer 0-4): how often do you have trouble wrapping up the fine details of a project, once the challenging parts have been done? (0 never, 1 rarely, 2 sometimes, 3 often, 4 very often). Clinically significant at sometimes or more. magent does not interpret the item. - `organization` (integer, required): Caller-assigned Kessler 2005 ASRS v1.1 Part A item 2 (integer 0-4): how often do you have difficulty getting things in order when you have to do a task that requires organization? Clinically significant at sometimes or more. magent does not interpret the item. - `remembering` (integer, required): Caller-assigned Kessler 2005 ASRS v1.1 Part A item 3 (integer 0-4): how often do you have problems remembering appointments or obligations? Clinically significant at sometimes or more. magent does not interpret the item. - `avoid_delay` (integer, required): Caller-assigned Kessler 2005 ASRS v1.1 Part A item 4 (integer 0-4): when you have a task that requires a lot of thought, how often do you avoid or delay getting started? Clinically significant at often or more. magent does not interpret the item. - `fidget` (integer, required): Caller-assigned Kessler 2005 ASRS v1.1 Part A item 5 (integer 0-4): how often do you fidget or squirm with your hands or your feet when you have to sit down for a long time? Clinically significant at often or more. magent does not interpret the item. - `motor` (integer, required): Caller-assigned Kessler 2005 ASRS v1.1 Part A item 6 (integer 0-4): how often do you feel overly active and compelled to do things, like you were driven by a motor? Clinically significant at often or more. magent does not interpret the item. ## 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. Method: `POST /api/calc/asrs` Max items: 25 Price: unit_amount + extra_item_amount * (n - 1) (unit 5000 atomic, extra 2000 atomic) Status: 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.

Returned before settlement; you are not charged. - HTTP 400 `invalid_items`: POST body must be a JSON object with only an items array Returned before settlement; you are not charged. - HTTP 400 `invalid_item_count`: items must be an array of 1 to 25 objects Returned before settlement; you are not charged. - HTTP 400 `invalid_item`: each items entry must be a JSON object Returned before settlement; you are not charged. Shared HTTP 402 and 503: https://magentlab.com/docs/payments ## Related tools - [PHQ-9](https://magentlab.com/docs/phq-9) — Sum nine caller-assigned Kroenke 2001 PHQ-9 integers (0-3) and return the published total (max 27), severity cutpoints, and ≥10 screen. - [GAD-7](https://magentlab.com/docs/gad-7) — Sum seven caller-assigned Spitzer 2006 GAD-7 integers (0-3) and return the published 0-21 total, 5/10/15 severity cuts, and ≥10 case-finding flag. - [CRAFFT](https://magentlab.com/docs/crafft) — Sum the six Knight 2002 CRAFFT items and return whether two or more answers are affirmative. ## 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. - GET the tool with Accept: application/json (do not send Accept: text/html unless you want the human paywall). - HTTP 402 means you have not paid. Decode the base64 PAYMENT-REQUIRED header. HTTP 503 is not a new quote. - Sign accepts[0] (exact, EIP-3009) with validBefore = now + maxTimeoutSeconds (600 seconds), or accepts[1] (batch-settlement deposit/voucher) on product GET. Ping and POST {items} stay exact. Magent retries transient facilitator 429/5xx before answering. - Retry the same URL with PAYMENT-SIGNATURE (base64 JSON of accepted and payload). Magent attaches canonical extensions.bazaar on CDP verify/settle; echoing 402 bazaar is optional. - Success is HTTP 200 JSON plus PAYMENT-RESPONSE. exact settles before the tool. batch-settlement verifies (and deposit-settles) before the tool and commits the charge after HTTP 2xx. HTTP 503: retry the same PAYMENT-SIGNATURE. Mint a new exact nonce only after a new HTTP 402. - offered `exact` on eip155:8453: Fixed-price USDC on Base. The buyer authorizes the advertised amount (EIP-3009). magent settles before the tool runs (paymentFlow upfront). extra.assetTransferMethod=eip3009 extra.paymentFlow=upfront. - offered `batch-settlement` on eip155:8453: Payment-channel vouchers claimed later in batches. Exact stays accepts[0]. Same-path POST {items} is still exact. extra.assetTransferMethod=eip3009 extra.paymentFlow=authorization. - not offered `upto`: Not offered. Usage-based: buyer authorizes a ceiling, seller settles the actual amount after work. Reserved for a future metered tool. Not for current calculators or code search. Same-path POST {items} is still scheme exact: one EIP-3009 authorization for GET unit plus $0.002 per extra item. That is not x402 batch-settlement (payment channels / vouchers). Shared HTTP 402 and 503 table: https://magentlab.com/docs/payments Stdio MCP (one process per host): https://magentlab.com/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.
