Study Notes

Longitudinal Study Overview

Longitudinal studies track the same participants over an extended period, utilizing various research methods like experiments, surveys, or observations.
Data is collected repeatedly over time, allowing for comparisons and analysis of trends within the same group.
Duration of studies can range from months to years.

Strengths of Longitudinal Studies

Effectively identify developmental trends and how individuals contribute to specific characteristics.
Use of the same participants minimizes bias from individual differences, improving the integrity of results.

Weaknesses of Longitudinal Studies

Participant attrition can occur, leading to potential biases if certain demographics are systematically excluded (e.g., individuals who move frequently or are less sociable).
Changes in the research team over time, such as funding loss or personnel changes, can impact the study's continuity and data collection process.
