Naturalistic Observations

15.1K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Area of Science:

  • Medical observation methods
  • Surgical safety and performance

Background:

  • Surgical procedures are complex environments with numerous potential distractors.
  • Effective communication and teamwork are critical for successful surgical outcomes.
  • Existing methods may not simultaneously capture both distractors and team dynamics.

Purpose of the Study:

  • To develop and validate a behavioral observation method for simultaneous assessment of distractors and communication/teamwork during surgery.
  • To establish the reliability of this method for lengthy surgical procedures exceeding 3 hours.

Main Methods:

  • An event-based coding system was developed using expert interviews, observations, and literature review.
  • Interobserver agreement was assessed using Cohen's kappa and intraclass correlation coefficient for 29 procedures.
  • Reliability was tested for entire surgeries, the first hour, and after 3 hours, including tired observers.

Main Results:

  • The system includes codes for five types of distractors and eight for communication/teamwork.
  • Cohen's kappa demonstrated good to excellent agreement for distractors (0.74-0.98) and communication/teamwork (0.70-1).
  • Intraclass correlation coefficients were excellent for distractors (0.86-0.99) and good to excellent for communication/teamwork (0.45-0.99), even after 3 hours.

Conclusions:

  • The developed observational method enables a single observer to simultaneously assess distractors and communication/teamwork.
  • High interobserver agreement is achievable even for long surgical procedures.
  • This method facilitates research into the effects of distractions and teamwork on surgical performance and patient outcomes.
