2. What are Questionnaries ?
Questionnaire can be defined as a standard data collection tool consisting of a series of questions or
items that are used to collect information related to health, symptoms, quality of life, and functional
status.
These responses are often considered Patient-Reported Outcomes (PROs) or Clinician-Reported
Outcomes(ClinROs).
purpose of collection
By comparing questionnaire responses before and after treatment, researchers assess how well the
drug or intervention worked.
Responses are coded and standardized (QSSTRESC/QSSTRESN), making them usable for statistical
models
which Supports primary or secondary endpoints.
Regulatory Evidence:use PRO data as evidence for :
• Treatment effectiveness.
• Drug labeling claims (e.g., "improves quality of life“)
• Risk-benefit analysis
3. Where are Questionnaires Captured?
In the CRF (Case Report Form), a specific section is designed for
questionnaire data collection. These may include: Paper CRFs –
Questionnaire form used during site visits .
eCRFs – electronic platforms (EDC systems like Medidata Rave, Oracle
InForm) where patients or site staff enter data.
12. Types of Questions in a Questionnaire
Here are some commonly used question types:
1. Open-ended questions:
• Open-ended questions offer participants a space into which they can answer by writing text.
eg :a) “What brings you in today?”
b) “Can you describe your symptoms?”
2. Closed-ended questions :
• Closed-ended questions contain include a clear instruction that participants may select more
than one response option (for example, 'tick all that apply’).
• Which of the following symptoms have you experienced in the past week?
Headache
☐
Nausea
☐
Fatigue
☐
Dizziness
☐
13. Types of Close Ended Questions
1. Dichotomous Question : These close ended question are indicative questions that can be answered either
in one of the two ways, “yes” or “no” or “true” or “false”.
• Do you currently take any medication for high blood pressure?
Yes
☐
No
☐
2. Multiple choice question :
• What types of pain have you experienced today?
Headache
☐
Muscle pain
☐
Joint pain
☐
Abdominal pain
☐
3. Likert Scale : The Likert scale is a commonly used in clinical trials to assess patient-reported outcomes,
such as symptoms, treatment satisfaction, and quality of life. It provides a range of response options—typically
from "Strongly Agree" to "Strongly Disagree“.
How severe was your joint pain in the past 24 hours?
None
☐
Mild
☐
Moderate
☐
Severe
☐
Very Severe
☐
14. 4. Rating Scales
A rating scale asks participants to rate their experience or opinion on a numeric or descriptive scale, such as 0 to 10
or from “Poor” to “Excellent.”
5. Checklist :
• Checklist-type questionnaires are a form of closed-ended questions commonly used in clinical trials to let participants
select all applicable responses from a list.
• These are widely used to collect consistent and analyzable data on multiple topics such as symptoms, medical history,
concomitant medications, and adverse events.
6. Matrix :
• A matrix questionnaire consists of a series of rows with items to be answered with a series of columns providing the
same answer options.
• The EORTC QLQ-C30 is an example of a matrix questionnaire.
7. pictorial questionnaires: (eg; Wong-Baker FACES, Pictorial Blood Assessment Chart) used in clinical trials, especially when
working with:
• Children
• Elderly
• Low-literacy populations
• Cognitively impaired patients
15. Questionnaire development
• If a questionnaire has previously been used in similar trials to the one
planned, its use will bring the added advantage that the results will be
comparable and may be combined in a meta-analysis.
• CIOMS Working Group prepares an example of the format and content
of a possible questionnaire.
Once the researcher has decided to design a new questionnaire, several
steps should be considered:
• If new questions are to be developed, the reading ease of the
questions can be assessed using the Flesch reading ease score.
• This score assesses the number of words in sentences, and the number
syllables in words. Higher Flesch reading scores indicate material that is
easier to read .
17. Regulatory guidelines
The International Conference on Harmonisation (ICH) of technical requirements for registration of
pharmaceuticals for human use states:
• The collection of data and transfer of data from the investigator to the sponsor can take place
through a variety of media, including paper case record forms, remote site monitoring systems,
and electronic transfer.
• Whatever data capture instrument is used, the form and content of the information collected
should be in full accordance with the protocol and should be established in advance of the
conduct of the clinical trial.
• Only collect data necessary for planned analysis.
Clear distinction must be made between:
Missing values
Zero values
Absent characteristics
18. Council for International Organisations of Medical Sciences (CIOMS)
advises that:
CIOMS is advising that all safety-related data can be captured neatly using
checkboxes, dropdowns, or predefined categories in a Case Report Form (CRF) or
questionnaire.
• When unexpected or unusual events occur — especially those that:
Do not fit into predefined categories.
need additional explanation.
What Are Predefined Data Fields?
These are structured fields like:
Checkboxes: (e.g., "Yes / No" for headache)
But not everything fits into these formats

19. • Did you experience any skin-related symptoms (e.g., rash, itching, redness)?"
• Answer choices:
☐ None
Mild
☐
Moderate
☐
Severe
☐
Very Severe
☐
• Patient Response:
Selects: “Moderate rash”
Follow-up :
• “Please describe the symptom if different from above or if more detail is needed”
Patient writes:
“Rash started as red spots but now turned into painful blisters across my chest
and arms within a day.”
20. History and origin
• The first documented patient-reported outcome dates back to 1914, marking early recognition
of patient feedback in healthcare.
• In 1970, the World Health Organization (WHO) led efforts to standardize outcomes in cancer
trials.
• In the early 1980s, especially in rheumatology, clinical trials began systematically incorporating
self-report tools
• EQ 5D instrument emerged in 1987 and was finalized in 1995, becoming a global standard for
measuring health-related quality of life.
• Starting in the 1990s, the shift from paper to electronic patient-reported outcomes (ePRO)
occurred—using tablets, smartphones, and IVR systems to collect data in real time, with better
compliance and reduced errors
21. Before QS Domain: Where Were Questionnaires Stored?
• Before CDISC introduced the QS (Questionnaires) domain in SDTMIG v1.2 (2008),
questionnaire data did not have a dedicated domain.
• Instead, it was stored inconsistently in other domains, based on the type of
question or sponsor preference.
Old Domain When It Was Used for
Questionnaires
Example
VS (Vital Signs)
If the response was numeric (e.g.,
pain scale 0–10)
Pain VAS score stored as VSTESTCD
= "PAIN"
MH (Medical History) If the question asked about prior
illness/symptoms
"Have you ever had depression?" →
MHTERM = Depression
CM (Concomitant Medications) If the question related to drug use "Are you taking aspirin?" → CMTRT
= Aspirin
FA (Findings About)
If the data was structured but had
no specific domain
A cognitive test result stored as a
finding about a condition
22. Development Flow

Action: Raise a query to site.
Invalid/Mismatched Responses :
Check that responses match allowed values.
Invalid Example: A response like “5” or “N/A”.
Out-of-Range Values :
For numerical scales (e.g., VAS score: 0–100), ensure data falls within range.
Date Validations :
Check that the date of questionnaire
Duplicate CRF Entries :
Remove or resolve duplicates.
28. SDTMIG
What is QS Domain?
• QS (Questionnaires) is a Findings domain that contains data for named, stand-
alone instruments designed to assess a psychological, physical, or health-related
trait or condition.
• Label of dataset- Questionnaires.
• Submission format- qs.xpt.
• structure -One record per questionnaire per question per time point per visit per
subject.
• Purpose –Tabulation.
• Topic variable- QSTESTCD
Who Maintains Questionnaires in CDISC?
• The CDISC QRS (Questionnaires, Ratings, and Scales) team develops supplements
for individual instruments,while the ADQRS team develops ADaM supplements
35. How efficacy is measured?
• Womac
Purpose: Measures pain, stiffness, and physical function in patients
with osteoarthritis (OA).
• Format: 24 items across 3 domains:
Pain – 5 items
Stiffness – 2 items
Physical Function – 17 items.
WOMAC is primarily used to assess efficacy of investigational treatments in OA
trials by measuring change from baseline over time.
36. Time Point WOMAC Pain Score Interpretation
Baseline 60 Moderate pain
Week 12 35 41% improvement in pain
Week 24 20 66% improvement — effective
37. How Is Safety Measured Using Questionnaires?
• Safety questionnaires capture:
Symptoms (e.g., fatigue, nausea, dizziness).
Severity of side effects.
Frequency or duration of adverse experiences.
Patient's perceived tolerability of treatment.
