Longitudinal research is complicated by high rates of ____________. a. deception b. observation c. attrition d. generalization
Short Answer
Expert verified
c. attrition
Step by step solution
01
Understand Key Terms
Longitudinal research refers to studies that are conducted over an extended period of time, sometimes over several years or even decades. The terms provided in the options are: deception (misleading participants about the true purpose of a study or the events that will transpire), observation (the action or process of observing something or someone carefully or in order to gain information), attrition (the process in which participants drop out of a study), and generalization (ability to apply findings from a research study to larger groups).
02
Reason Out the Answer
In longitudinal studies, it's less likely that high rates of deception or observation complicate the research. Generalization is typically a goal, not a complication. However, attrition (losing participants over time) is indeed a major complication in longitudinal research. As time goes by, people may choose to stop participating or could be lost for a variety of other reasons, thereby potentially skewing the results.

Attrition in Longitudinal Research
Attrition is a major challenge in the field of longitudinal research. It refers to the process where participants gradually drop out of a study over time. This phenomenon can significantly affect the outcome and credibility of the research. As you might imagine, losing participants can lead to incomplete data or biased results.
Attrition can occur due to various reasons such as lack of interest from participants, personal issues, moving away, or even changes in health.
Maintaining participation over many years requires sustained interest and engagement, which can be difficult to achieve. Here are some strategies researchers use to combat attrition:

Maintaining participation over many years requires sustained interest and engagement, which can be difficult to achieve. Here are some strategies researchers use to combat attrition:
- Regular follow-ups and reminders for participants.
- Building a strong relationship with participants.
- Offering incentives, such as monetary rewards or gifts.
- Keeping the study interesting and relevant to the participants.
Longitudinal Study Challenges
Longitudinal studies come with their own unique set of challenges apart from attrition. First, they require a significant time commitment, which can be daunting both for participants and researchers.
Conducting a study over several years necessitates proper planning and sustained funding, which is not always easy to secure.
The design of the study must be meticulous to ensure that it continuously aligns with the research objectives over the years.
Additionally, researchers must ensure consistent data collection methods. Inconsistencies can arise due to changes in technology, measurement tools, or even shifts in the research team's personnel. Another challenge is dealing with the variability and unpredictability of life events, which can affect participant behavior and outcomes.
Longitudinal studies must be adaptable to such changes while striving to maintain the integrity of the data.

Research Participant Dropout
Participant dropout is another term closely related to attrition in research. This occurs when individuals who initially agreed to take part in the study choose to leave before it is completed.
Dropouts can happen at any stage and may be influenced by several factors such as changes in interest, life circumstances, and sometimes misunderstanding of the study's purpose.
Researchers often try to minimize dropout rates by ensuring clear communication. This includes explaining the study's importance, the participant's role, and the potential benefits. Furthermore, addressing participant concerns promptly and maintaining a good rapport can help.
A significant dropout rate can lead to biased results, as those who remain may not represent the original sample's diversity. For researchers, managing participant dropout effectively is crucial to maintain the study's validity and reliability.
