Summary
Researchers developed and validated a new risk assessment scale for pathological scarring. This 12-item scale demonstrates strong psychometric properties, making it suitable for clinical and research use in identifying at-risk patients.
Area of Science:
- Dermatology
- Medical Statistics
- Clinical Research Methodology
Background:
- Pathological scarring poses a significant clinical challenge, necessitating reliable tools for risk assessment.
- Current methods for identifying patients at risk of pathological scarring may lack comprehensive validation.
- Developing a validated scale can improve early identification and management strategies.
Purpose of the Study:
- To develop a novel risk assessment scale for pathological scarring.
- To rigorously validate the psychometric properties of the developed scale, including validity and reliability.
- To establish a tool for use in clinical practice and research settings.
Main Methods:
- A methodological study involving literature review, qualitative research, and Delphi expert consultation for scale development.
- Psychometric evaluation of the scale in a cohort of 409 patients.
- Assessment of construct validity, content validity (I-CVI, S-CVI), internal consistency reliability (Cronbach's α), and interrater reliability (Kappa).
Main Results:
- A 12-item scale across three dimensions was developed.
- Factor analysis identified four common factors explaining 62.22% of the variance.
- The scale demonstrated good content validity (S-CVI=0.82), internal consistency (Cronbach's α=0.74), and interrater reliability (Kappa=0.73).
Conclusions:
- The developed pathological scarring risk assessment scale exhibits adequate construct validity, content validity, and reliability.
- The scale is suitable for identifying patients at risk of pathological scarring in research and clinical settings.
- Further validation in diverse populations and settings is recommended to confirm generalizability.

2.7K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...
