This document describes the CDISC implementation of the Hamilton Depression Rating Scale 17-Item (HAMD 17) instrument.
CDISC created this case report form ( CRF ) to represent the instrument, which CDISC believes is in the public domain. This is not an endorsement of the instrument. The The creation of this instrument was based on based on published articles describing the instrument. Sponsors may create this instrument’s CRF using their style guidelines, but they need to maintain the wording and order of the questions/items and responses as described on the CRF. describing the instrument.

The HAMD 17 is a multiple-choice instrument that clinicians may use to assess the severity of major depression. Max Hamilton originally published the scale in 1960 and revised it in 1967. The measure, which is designed for adult subjects, rates the severity of symptoms observed in depression (e.g., low mood, insomnia, agitation, anxiety, weight loss). It consists of 17 items, each rated on a 3-, 4-, or 5-point scale. A total score between 0-53 is also captured.
The scale points include original scores include a numeric rating (0-2, 0-3, or 0-4) and a definition of what is represented by the rating (e.g., 0 = "Absent.", 4 = "Incapacitating."). For the HAMD 17, RSORRES is populated with the text description while the numeric rating is represented in the standardized character and numeric result variables RSSTRESC and RSSTRESN.
The time period of evaluation for the HAMD 17 is populated in the RSEVLINT variable in ISO 8601 format when the evaluation interval can be precisely described as duration. The evaluation interval for the HAMD 17 is determined based on the sponsor's stated evaluation interval.
The HAMD 17 instrument includes a total score that is considered as captured data on the CRF and is not considered as derived in the example below. This score may be submitted in SDTM or derived in the Analysis Data Model (ADaM).
If operationally defined by the sponsor, it is the sponsor's responsibility to set the --DRVFL flag based on their eCRF process to derive subtotals and total scores. An investigator-derived score will be considered a captured score and not flagged. When subtotal and total scores are derived by the sponsor, the derived flag (--DRVFL) is set to "Y". However, when the subtotal and total scores are received from a central provider or vendor, the value would go into --ORRES and --DRVFL would be null (see SDTMIG Section 4.1.Records are created in rs.xpt for every instrument item:
For items with no data, RSORRES, RSSTRESC, and RSSTRESN are all missing and RSSTAT = "NOT DONE". If the reason is known then that reason is represented in RSREASND (e.g., RSREASND = "PREFER NOT TO ANSWER"). If the reason is unknown, then RSSTAT = "NOT DONE" and RSREASND is missing.
- Due to the variability of copyright holder and public domain derived subscore and overall score generation processes, records are not included for derived subscores or overall scores that are not provided.

Some items on the HAMD 17 may be conditionally branched per the instrument instructions. Item 16 contains 2 components: Part A, which is loss of weight according to the patient, and Part B, which is loss of weight according to weekly measurements. Only 1 of these items is answered when administering the HAMD 17 instrument

The HAMD 17 instrument includes an overall score that is considered as captured data on the CRF and is not considered as derived in the example below. This overall score may be submitted in SDTM or derived in the Analysis Data Model (ADaM) per scoring instructions from the refwrence articles.
Item 16 contains 2 components: Part A, which is loss of weight according to the patient, and Part B, which is loss of weight according to weekly measurements. Only 1 of these items is answered when administering the HAMD 17 instrument- Subscores and overall scores are represented in--ORRES, --STRESC, and --STRESN.

737 - If subscores or overall scores are received or derived by the sponsor, it is recommended that they are submitted to SDTM and verified in ADaM whenever feasible. It is the sponsors repsonsibility to do this verification based on the instrument's user manual or instructions from the copyright owner.
