Brief Summary
Pain intensity is commonly measured in research and clinical settings. Primary objective: To evaluate psychometric properties (validity, reliability, and utility) of 5 pain measurement tools: a verbal 11-point NRS, the FPS-R, a 6-point VDS, an 11-point NRS, and a 100 mm VAS in a sample of cesarean section patients. Secondary objectives: To evaluate whether the (new) word "very severe pain" is easier for patients to understand in comparison to the (old) word "worst pain imaginable. To evaluate whether the (new) word "overall pain" is easier for patients to understand in comparison to the (old) word "average pain".

Outcome Measures
Primary Outcomes (6)
To evaluate the psychometric properties of the Verbal 11-point Numerical Rating Score (VNRS) in cesarean section patients.
To evaluate the psychometric properties of the 11-point Verbal Numerical Rating Score (VNRS) which 0 means "no pain" and 10 means "worst pain imaginable" in a sample of cesarean section patients.
January 2024 - December 2025
To evaluate the psychometric properties of the Faces Pain Scale - Revised (FPS-R) in cesarean section patients.
To evaluate the psychometric properties of the Faces Pain Scale - Revised (FPS-R) which comprises with 6 faces ranging from the first neutral face as "no pain" and the sixth face as "the most severe pain" in a sample of cesarean section patients.
January 2024 - December 2025
To evaluate the psychometric properties of the 6-point Verbal Descriptive Scale (VDS) in cesarean section patients.
To evaluate the psychometric properties of the 6-point Verbal Descriptive Scale (VDS) ranging from no pain, very mild pain, mild pain, moderate pain, severe pain and very severe pain in a sample of cesarean section patients.
January 2024 - December 2025
To evaluate the psychometric properties of the 11-point Numerical Rating Scale (NRS) in cesarean section patients.
To evaluate the psychometric properties of the 11-point Numerical Rating Scale (NRS) where 0 means "no pain" and 10 means "worst imaginable pain" in a sample of cesarean section patients.
January 2024 - December 2025
To evaluate the psychometric properties of the 100 mm Visual Analog Scale (VAS) in cesarean section patients.
To evaluate the psychometirc properties of the 100 mm Visual Analog Scale (VAS) where 0 mm (left end of the line) represents "no pain" and 100 mm (right end of the line) represents "worst pain imaginable" in a sample of cesarean section patients.
January 2024 - December 2025
To directly compare the psychometric properties of 5 pain measurement tools (VNRS, FPS-R, VDS, NRS and VAS in a sample of cesarean section patients.
To directly compare the psychometric properties of 5 pain measurement tools in a sample of cesarean section patients: 1. the VNRS 2. the FPS-R 3. the VDS 4. the NRS 5. the VAS
January 2024 - December 2025
Secondary Outcomes (2)
To compare the easiness to respond between the newly proposed words and the previously used words, using percentage of correct response.
January 2024 - December 2025
To compare the easiness to respond between the newly proposed words and the previously used words, using percentage of correct response.
January 2024 - December 2025
Interventions
Patients to complete a questionnaire on measurement of pain intensity.
Eligibility Criteria
Patients who undergo cesarean delivery.
You may qualify if:
- Age ≥ 18 years old
- Endorsing having post-cesarean section pain in the first 72 hrs following the operation
- Can speak and write in Thai, as determined by an ability to answer details about demographic information
- No motor deficits in the hands that would interfere with their ability to respond to a paper-and-pencil questionnaire
You may not qualify if:
- Age less than 18 years old
- Lack of fluency in Thai
- Neurological disorder or psychiatric illness that would interfere with participation or ability to provide informed consent
- Refusal to participate in the study
