Prospective Study
Prospective Study
A study design where participants are followed forward in time to see if they develop a certain outcome based on their exposure to a specific factor.
Prospective vs. Retrospective
Prospective vs. Retrospective
The main difference lies in the direction of data collection. Prospective studies gather data as events unfold, while retrospective studies analyze past data.
Recall Bias
Recall Bias
Recall bias is a systematic error that occurs when participants' memories of past events are inaccurate or incomplete.

Study Notes
Study Design
- A prospective study design starts with the exposure and follows participants forward in time to observe the development of outcomes.
Prospective vs. Retrospective Studies
- The main difference between prospective and retrospective studies is the direction of inquiry: prospective studies move forward in time, while retrospective studies look backward in time.
Bias in Prospective Studies
- Selection bias is less prone in prospective studies because participants are selected based on their exposure status and then followed over time.
Temporal Sequence
- The temporal sequence in prospective studies refers to the chronological order in which events occur, ensuring that the cause precedes the effect.
Strength of Prospective Studies
- The strength of prospective studies lies in their ability to establish causal relationships between exposures and outcomes, as they allow researchers to observe the development of outcomes over time.
