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 is one disadvantage of a longitudinal study?
Longitudinal Studies Can Be Expensive
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 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 are two primary disadvantages of conducting longitudinal studies?
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.
Why are longitudinal studies expensive?
Longitudinal research enables researchers to gather a large volume of data. ... Despite their benefits, longitudinal studies are exceedingly expensive . Because they last so long, they often require many researchers, some of whom may leave the project before its completion.
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 problem with longitudinal research?
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.
How does a longitudinal study benefit the child?
Longitudinal data enable us to: Track children’s development throughout childhood and teenage years , to adulthood and beyond – including influences, aspirations and cognitive outcomes. Study the links between family background, educational achievements and later outcomes.
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.
What is the difference between cohort and longitudinal study?
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).
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.
Are longitudinal studies reliable?
Longitudinal data collection allows researchers to build up a more accurate and reliably ordered account of the key events and experiences in study participants’ lives. Understanding the order in which events occur is important in assessing causation.
Are longitudinal studies qualitative or quantitative?
Quite often, a longitudinal study is an extended case study, observing individuals over long periods, and is a purely qualitative undertaking .
Can a longitudinal study be on one person?
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.
