This document discusses developmental research designs, which examine phenomena with reference to time. It describes two main types: cross-sectional and longitudinal research designs. Cross-sectional design involves collecting data at a single point in time, while longitudinal design collects data over an extended period. Longitudinal design is further divided into trend studies, panel studies, and follow-up studies. Trend studies investigate changes in a population sample over time, while panel studies follow the same individuals over multiple time periods. Follow-up studies determine subsequent conditions of subjects with a prior condition or intervention.
DEVELOPMENTAL RESEARCH DESIGN
- 1. DEVELOPMENTAL RESEARCH DESIGN DR. MAHESWARI JAIKUMAR maheswarijaikumar2103@gmail.com
- 2. • Developmental research designs examines the phenomenon with reference to time. • This design is generally used as adjunct research designs with other research designs such as cross- sectional-descriptive, longitudinal- correlational research design.
- 3. TYPES • 1. CROSS-SECTIONAL RESEARCH DESIGN. • 2. LONGITUDINAL RESEARCH DESIGN.
- 4. CROSS-SECTIONAL RESEARCH DESIGN • Cross-sectional research designs is the one in which the researcher collects data at a particular point of time.(one time data collection).
- 5. • Cross-sectional design is easier and convenient to carry out.
- 6. LONGITUDINAL RESEARCH DESIGN • Longitudinal research designs is used to collect data over a period of time. (long time study)
- 7. • The value of the longitudinal design is in its ability to demonstrate change over a period of time. • Longitudinal studies are classified into three types : TREND STUDIES, PANEL STUDIES, FOLLOW-UP STUDIES.
- 8. TREND STUDIES • Trend studies aims at investigating a sample from a general population over a time with respect to some phenomenon.
- 9. • Trend studies permit researchers to examine pattern and rate of changes and to make prediction about future direction based on previously identified patterns and rates of changes.
- 10. PANEL STUDIES • A sample of people involves in the study are referred to as a panel.
- 11. • In panel studies, same people are involved and over a period of time because they become more informative on the phenomenon than the subjects in trend studies because ue the researcher cannot only examine the patterns of change, but also reasons for change.
- 12. • The same selected people are contacted for two or more times to collect further data.
- 13. FOLLOW - UP STUDIES • Follow-up studies are undertaken to determine the subsequent states of subjects with a specified condition or those who have received a specific intervention.
