Naturalistic Observations

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...

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Area of Science:

  • Public Health
  • School Health Programs
  • Health Promotion

Background:

  • Elementary schools play a crucial role in shaping student health behaviors.
  • Identifying opportunities to enhance student nutrition and physical activity is essential for overall well-being.
  • The School Environment Index (SEI) was developed to aid schools in this process.

Purpose of the Study:

  • To pilot test the School Environment Index (SEI) for its ability to measure program progress.
  • To evaluate the SEI's performance based on reliability, validity, feasibility, and usability.

Main Methods:

  • The study utilized data from 214 SEIs completed by 69 elementary schools between 2015 and 2019.
  • Evaluation focused on National Quality Forum measure evaluation components.
  • Statistical analysis included Cronbach's alpha and intraclass correlation.

Main Results:

  • The SEI demonstrated adequate internal consistency (Cronbach's α = 0.79) and sensitivity to change (0.41).
  • Completion time was a median of 11 minutes, indicating feasibility.
  • Reliability was found to be moderate (intraclass correlation = 0.36).

Conclusions:

  • The SEI is a feasible and useful tool for identifying areas to improve student nutrition and physical activity policies.
  • The index shows adequate internal consistency and sensitivity to change.
  • Improving SEI reliability may require increasing the number of respondents per school.
