Cerebrospinal Fluid Leak Repair Simulation Model: Face, Content, and Construct Validation

Area of Science:

• Neurosurgery
• Surgical Simulation
• Medical Education

Background:

• Cerebrospinal fluid leak (CSFL) repair simulation models are scarce.
• Such models are valuable tools for skull base reconstruction surgery training.

Purpose of the Study:

• Assess the face, content, and construct validity of a CSFL repair simulation model.
• Evaluate the model's efficacy in training surgical residents and experts.

Main Methods:

• Eight novices and eight experts performed skull base reconstruction on cadaveric heads.
• Participants' performances were scored using the Global Rating Scale of Operative Performance (GRSOP) and a Specific Skull Base Reconstruction Checklist (SBRC).
• Experts completed a questionnaire to assess face and content validity.

Main Results:

• Expert questionnaire responses indicated high face and content validity (4.13-4.88/5).
• High internal consistency reliability (Cronbach's Alpha: 0.913) and intraclass correlation (0.941) were observed.
• Statistically significant differences in construct validity were found between novices and experts (P < 0.001).

Conclusions:

• The CSFL repair simulation model demonstrated face, content, and construct validity.
• The model effectively facilitates the acquisition of technical skills for skull base reconstruction.
• Realistic features make the model a valuable tool for surgical education and training courses.
