The ability to identify and relate events to particular exposures and to further define these exposures with regards to presence timing and chronicity. The strengths of longitudinal studies They allow researchers to trace developments over time rather than just taking a one-off snapshot of one moment. The primary disadvantage of using longitudinal studies for research is that long-term research increases the chances of unpredictable outcomes.

Participants Tend to Drop Out Over 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. Often requires fewer participants since only one group is.

Whilst this did show the long term effects the method is time consuming. The study lasted for 2 years looked at the way children learn to communicate. List of Disadvantages of Longitudinal Studies.

The single-cohort long-term longitudinal survey has many advantages in comparison with a cross-sectional survey in advancing knowledge about offending and other types of psychopathology notably in providing information about onset and desistance about continuity and prediction and about within-individual change. That reliance on the individual makes it possible for the data to be corrupted or conclusions to be inaccurate. Cohort studies more clearly indicate the temporal sequence between exposure and outcome because in a cohort study subjects are known to be disease-free at the beginning of the observation period when their exposure status is established.

They are often large-scale quantitative surveys and tend to be used by positivists although some studies for example the Seven Up study which followed 14 kids from the age of 7 every 7 years as they grew up are more qualitative and preferred by interpretivists.

If you are going to study a group of 1500 participants once a year then obviously some of these participants will no longer be able to be part of the study. Disadvantages Longitudinal studies are time-consuming and often more expensive than other types of studies so they require significant commitment and resources to be effective. High in validity - people usually do not remember past events and if they were asked about their past they would not remember 2.

Longitudinal studies are better to establish the correct sequence of events identify changes over time and provide insight into cause-and-effect relationships but they also tend to be more expensive and time-consuming than other types of studies. Longitudinal studies rely on the expertise creativity and honesty of individual researchers for authentic conclusions. What are the pros and cons of a longitudinal study.
