Longitudinal Studies

Longitudinal Studies
- A study of people over a long period of time.
- The aim is to record the changes over time.

- Longitudinal studies are useful when the researcher wants to:
- Track changes in the individual.
- AND track changes in the group that the individual is part of.

Advantages
- Researchers use longitudinal studies to monitor changes in many aspects of people's social lives such as educational achievement, employment and poverty.
- Longitudinal studies are valid since qualitative data is collected through observations and interviews.
- Longitudinal studies can track changes and establish trends.

Disadvantages
- They are time consuming.
- They are costly since it is hard to keep track of the participants over time as they might move somewhere else.
- The participants might decide at some point they don’t want any longer to be part of the study because of illness, death, personal reasons, i.e. the attrition rate.

Disadvantages cont.
- If many participants decide to withdraw, the chances are that the sample will no longer be representative.
- A non-representative sample means that the data collected cannot be used to make generalisations.
- Participants might change their behaviour because they know they are being monitored, producing invalid data (observer effect).
