The BODY-Q Belly Button Scale: A Development and Validation Study
Aesthetic Surgery Journal
|August 21, 2025
Summary
A new BODY-Q scale was developed to measure patient satisfaction with their belly button appearance after abdominoplasty. This validated tool helps assess outcomes from the patient
Area of Science:
- Plastic Surgery
- Patient-Reported Outcomes
- Psychometrics
Background:
- Belly button repositioning is crucial in abdominoplasty and reconstructive surgery.
- Patient satisfaction with belly button appearance is poorly understood.
- No standardized patient-reported outcome measure exists for this specific outcome.
Purpose of the Study:
- To develop and validate a BODY-Q scale for assessing patient satisfaction with belly button appearance.
- To create a reliable and valid instrument for clinical and research use.
Main Methods:
- Qualitative interviews informed scale development (Phase 1).
- Quantitative field-testing via crowdsourcing (Phase 2).
- Rasch measurement theory (RMT) analysis for item reduction, reliability, and validity assessment.
Main Results:
- A six-item BODY-Q Belly Button scale was finalized after qualitative refinement.
- Psychometric validation in 372 participants confirmed reliability (PSI, Cronbach's alpha >0.81).
- Rasch model fit and 89% hypothesis acceptance supported construct validity.
Conclusions:
- The validated BODY-Q Belly Button scale reliably measures patient satisfaction.
- This scale is suitable for clinical practice and research to evaluate patient perspectives on belly button aesthetics.

01:27Assessing Body Temperature - Rectal
6.4K
Rectal temperature measurement is considered the most precise method for assessing core body temperature and typically registers higher than oral temperature. For adults, the rectal thermometer should be inserted 1 to 1.5 inches into the rectum to obtain the most accurate reading.
Follow these steps for rectal temperature assessment:
Step 1: Perform hand hygiene and don clean gloves to prevent cross-infection.
Step 2: Position the patient in a side-lying position to better visualize the rectal...

Here are the steps to accurately measure oral temperature using an electronic thermometer:
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...

01:23Assessment of the Abdomen III: Palpation
1.2K
Palpation is a crucial tactile examination method for assessing abdominal organs and detecting conditions like tenderness, distention, masses, or fluid. It involves both light and deep palpation techniques, each serving specific diagnostic purposes. Light palpation helps identify tenderness and other surface-level indicators, while deep palpation locates and assess abdominal masses and organ boundaries. A skilled professional can gather valuable insights through palpation, including evaluating...

Procedural Guide for Assessing Axillary Body Temperature using a Digital Thermometer:
Step 1: Perform hand hygiene and put on clean gloves to maintain infection control and prevent cross-contamination.
Step 2: Prepare the patient by explaining the procedure to ensure understanding and cooperation. Ensure privacy, expose the axilla, and inform the patient that minimal movement is crucial for an accurate reading.
