Blinding

Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

Area of Science:

  • Public Health
  • Transportation Safety
  • Human-Computer Interaction

Background:

  • Over 6400 American pedestrians die annually, with increasing trends attributed partly to mobile technology distractions.
  • Distracted driving has received attention, but distracted pedestrian behavior remains a significant, under-addressed public safety concern.

Purpose of the Study:

  • To evaluate Bluetooth beacon technology as a method to alert and warn pedestrians approaching intersections.
  • To assess the impact of a smartphone application utilizing beacons on distracted pedestrian behavior and perceived risk.

Main Methods:

  • A cross-over trial involving 411 adults at a busy urban university intersection.
  • Implementation of Bluetooth beacons transmitting alerts to a smartphone app, with participants experiencing periods with and without the app activated over 10 weeks.
  • Logistic regression analysis to evaluate changes in pedestrian behavior and perceived risk, adhering to CONSORT guidelines.

Main Results:

  • The study aims to gather data to determine if the intervention effectively changes distracted pedestrian behavior.
  • Analysis will focus on the likelihood of key behavioral outcomes and changes in perceived risk.

Conclusions:

  • Successful implementation offers potential for broad distribution to reduce distracted pedestrian behavior.
  • The study will discuss the feasibility, acceptability, and scalability of the Bluetooth beacon intervention for enhancing pedestrian safety.
