Longitudinal studies require enormous amounts of time and are often quite expensive. Because of this, these studies often have only a small group of subjects, which makes it difficult to apply the results to a larger population.
What are problems of a longitudinal study?
However, the longitudinal survey also has significant problems, notably in confounding aging and period effects, delayed results , achieving continuity in funding and research direction, and cumulative attrition.
What is the main drawback of longitudinal studies quizlet?
They require enormous amounts of time. Another huge drawback to any longitudinal study is the great amount of time it needs to collect all the data that is needed . Usually, it takes a long period of time to gather results before you can start making patterns.
What are some advantages and disadvantages of longitudinal studies?
- They can show clear variable patterns over time. ...
- They allow for clear focus and validity. ...
- They can provide useful data. ...
- They have more power than cross-sectional studies. ...
- They are perfect for doing research on developmental trends.
What is a weakness of longitudinal studies?
The key advantage to longitudinal studies is the ability to show the patterns of a variable over time. ... Another weakness is that while longitudinal data is being collected at multiple points, those observation periods are pre-determined and cannot take into account whatever has happened in between those touch points .
Why are longitudinal studies bad?
1. They require huge amounts of time . Time is definitely a huge disadvantage to any longitudinal study, as it typically takes a substantial amount of time to collect all the data that is required. Also, it takes equally long periods to gather results before the patterns can even start to be made.
Why are longitudinal studies good?
The benefit of a longitudinal study is that researchers are able to detect developments or changes in the characteristics of the target population at both the group and the individual level . The key here is that longitudinal studies extend beyond a single moment in time.
What are the three types of longitudinal studies?
There are a range of different types of longitudinal studies: cohort studies, panel studies, record linkage studies . These studies may be either prospective or retrospective in nature.
What is most likely the biggest problem with longitudinal research?
The biggest problem in longitudinal research comes from changing historical context . Seeks to understand how and why people of all ages and circumstances change or remain the same over time. ... a time when a certain type of development is most likely, although it may still happen later.
What is a longitudinal cohort study?
Listen to pronunciation. (LON-jih-TOO-dih-nul KOH-hort STUH-dee) A type of research study that follows large groups of people over a long time . The groups are alike in many ways but differ by a certain characteristic (for example, female nurses who smoke and those who do not smoke).
What is the primary advantage of longitudinal studies quizlet?
= collecting data from long periods help in determining patterns , cause and effect relationships and connections. = these studies are high in validity and are great for picking up long-term changes. = more reliable as you can track the consistency of data and remove any anomalies that may hinder the datas accuracy.
Is longitudinal and cohort study the same?
Longitudinal research is a type of correlational research that involves looking at variables over an extended period of time. ... Cohort study is a particular type of longitudinal study which involves comparison groups (exposed group vs non-exposed group to the factor in question).
How many people participate in a longitudinal study?
Longitudinal studies do not require large numbers of participants (as in the examples below). Qualitative longitudinal studies may include only a handful of participants, and longitudinal pilot or feasibility studies often have fewer than 100 participants.
What is the difference between prospective and longitudinal studies?
Longitudinal study designs
Repeated cross-sectional studies where study participants are largely or entirely different on each sampling occasion; Prospective studies where the same participants are followed over a period of time.
How do you conduct a longitudinal study?
- Step one: Build a collaborative team and set a long-term plan. ...
- Step two: Develop a strong theoretical framework to support research questions. ...
- Step three: Design a comprehensive study that maps onto study aims. ...
- Step four: Determine the sample and develop a recruitment plan. ...
- Step five: Select and/or develop measures.
Why do people drop out of longitudinal studies?
Dropout in longitudinal surveys has three separate sources: failure to locate research participants, failure to contact participants , and failure to achieve cooperation.
