Longitudinal Research

13.5K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Assumptions of Survival Analysis

448
Survival models analyze the time until one or more events occur, such as death in biological organisms or failure in mechanical systems. These models are widely used across fields like medicine, biology, engineering, and public health to study time-to-event phenomena. To ensure accurate results, survival analysis relies on key assumptions and careful study design.

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Public Health

Background:

  • Longitudinal research requires sustained participant engagement.
  • The Adolescent Brain Cognitive Development (ABCD) study aims for 10-year participant involvement.
  • Differential retention can compromise study generalizability.

Purpose of the Study:

  • To outline the retention framework for the ABCD study.
  • To describe concrete strategies for maintaining participant engagement.
  • To ensure high retention rates across diverse participant demographics.

Main Methods:

  • Regular contact: bi-annual phone calls and annual in-person visits.
  • Targeted outreach to adolescents during developmental transitions.
  • Development of a comprehensive retention strategy framework.

Main Results:

  • The ABCD study employs multifaceted retention efforts.
  • Strategies are designed to support both youth and families.
  • Focus on minimizing differential retention based on risk or demographic factors.

Conclusions:

  • Effective retention strategies are crucial for the success of long-term developmental studies.
  • The ABCD study's approach aims to maximize data integrity and generalizability.
  • Sustained engagement is key to understanding adolescent brain development.
