What Effects Are A Major Problem Found In Cross Sectional Research?

What effects are a major problem found in cross sectional research? A disadvantage of cross-sectional research is that

it just tells researchers about differences, not true changes

. Also, researchers have to worry about whether change is due to age/development or generational/cohort effect.

What is a major disadvantage of cross-sectional research?

A disadvantage of cross-sectional research is that

it just tells researchers about differences, not true changes

. Also, researchers have to worry about whether change is due to age/development or generational/cohort effect.

Which of the following is a limitation of cross-sectional research?

The primary limitation of cross-sectional studies is that

the temporal link between the outcome and the exposure cannot be determined

because both are examined at the same time.

What is one disadvantage of the cross-sectional method of observation?

Researchers cannot be sure what factors account for differences among participants

.

Why are cross-sectional studies unreliable?

Cross-sectional studies

cannot establish a cause-and-effect relationship or analyze behavior over a period of time

. To investigate cause and effect, you need to do a longitudinal study or an experimental study.

What is a major limitation of a cross-sectional design and developmental research?

One of the primary limitations of cross-sectional research is that

the results yield information about age differences not necessarily changes with age or over time

.

What is a cross-sectional effect?

In economics, cross-sectional studies typically involve the use of cross-sectional regression, in order to sort out the existence and magnitude of causal effects of one independent variable upon a dependent variable of interest at a given point in time.

What are the strengths and weaknesses of cross-sectional study?

• Relatively quick and easy to conduct (no long periods of follow-up).
• Data on all variables is only collected once.
• Able to measure prevalence for all factors under investigation.
• Multiple outcomes and exposures can be studied.

What are the advantages and disadvantages of cross-sequential research?

Benefits of this design include

requiring fewer participants and more easily controlling for group differences and cohort effects

. Disadvantages include attrition and participant’s providing biased responses. A cross-sequential study is a mix of cross-sectional and longitudinal designs.

What is the primary problem with interpreting the results of cross-sectional studies of intelligence?

Cross-sectional research may be misleading because

each cohort has its own unique history of life experiences

and because in each generation, academic intelligence increases a result of improved educatoin and health.

What is cross-sectional method in research?

Cross-sectional study design is

a type of observational study design

. In a cross-sectional study, the investigator measures the outcome and the exposures in the study participants at the same time.

Which of the following is a disadvantage of a cross-sectional design?

Disadvantages of Cross-Sectional Study

Cannot be used to analyze behavior over a period to time

. Does not help determine cause and effect. The timing of the snapshot is not guaranteed to be representative. Findings can be flawed or skewed if there is a conflict of interest with the funding source.

Which of the following best describes the main problem with cross-sectional studies quizlet?

Which of the following best describes the main problem with cross-sectional studies? Longitudinal studies confound age effects with time-of-testing effects.

Difficulty in performing everyday tasks that are required for living independently

.

What is an example of a cross-sectional study?

Another example of a cross-sectional study would be

a medical study examining the prevalence of cancer amongst a defined population

. The researcher can evaluate people of different ages, ethnicities, geographical locations, and social backgrounds.

What Cannot be studied using cross-sectional methods?

Prompts Further Study

While cross-sectional studies cannot be used to determine

causal relationships

, they can provide a useful springboard to further research.

How do you minimize the cross-sectional study bias?

Selection bias can be minimized in cross sectional studies by

trying to contact those who cannot be contacted during the survey timings

. It is worthwhile going through following lines in the endgame first (1): “Therefore, ownership of a phone and listing in the directory would have influenced inclusion in the study.

Are cross-sectional studies reliable?

Cross-sectional studies serve many purposes, and the cross-sectional design is the most relevant design when assessing the prevalence of disease, attitudes and knowledge among patients and health personnel, in validation studies comparing, for example, different measurement instruments, and in reliability studies.

What are the biases in cross-sectional study?

Bias in cross-sectional studies.

Selection bias

occurs when the study participants are systematically different in their characteristics compared with eligible participants who were not selected for the study.

Why cross-sectional data do not determine cause-and-effect?

However, cross-sectional studies may not provide definite information about cause-and-effect relationships. This is because

such studies offer a snapshot of a single moment in time; they do not consider what happens before or after the snapshot is taken

.

What are advantages and disadvantages of cross-sectional and longitudinal designs?

Cross-sectional study is conducted with different samples. Longitudinal study is conducted with the same sample over the years.

Cross-sectional studies cannot pin down cause-and-effect relationship. Longitudinal study can justify cause-and-effect relationship.

Which developmental design has a serious problem with loss of participants?

Some major issues with

longitudinal studies

include the loss of participants. If you run an experiment for 10 years, some are going to move, and some will just want to stop participating.

What are the pros and cons of experimental research?

• It gives researchers a high level of control. …
• It allows researchers to utilize many variations. …
• It can lead to excellent results. …
• It can be used in different fields. …
• It can lead to artificial situations. …
• It can take a lot of time and money. …
• It can be affected by errors.

Do cross-sectional studies have independent and dependent variables?

Cross-sectional studies let researchers study one independent variable as the main focus and examine its effects on one or more dependent variables

. Similar research may look at the same variable of interest, but each study observes a new set of subjects.

What level of research is a cross-sectional study?

Cross sectional study designs and case series form

the lowest level of the aetiology hierarchy

. In the cross sectional design, data concerning each subject is often recorded at one point in time.

How do you collect data from a cross-sectional study?

Cross-sectional data can be collected by

self-administered questionnaires

. Using these instruments, researchers may put a survey study together with one or more questionnaires measuring the target variable(s).

Why do we use cross-sectional design?

Because you only collect data at a single point in time, cross-sectional studies are relatively cheap and less time-consuming than other types of research

. Cross-sectional studies allow you to collect data from a large pool of subjects and compare differences between groups.

Is cross-sectional study qualitative or quantitative?

Most cross-sectional studies are quantitative

. They gather data through interviews, questionnaires, and focus groups over a certain period in time which may be in the past or the present, and then analyze the results.

Which factor is a problem with longitudinal research?

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 is a good sample size for a cross-sectional study?

A smaller ‘d’ implies a larger sample size

. Therefore, the choice of ‘p’ is crucial. = 400 this sample size will enable us to detect the truth if the prevalence is between 18-22% (or more). = 1900 this sample size will enable us to detect the truth if the prevalence is between 4-6% (or more).

Why do a cross-sectional study?

The benefit of a cross-sectional study design is that

it allows researchers to compare many different variables at the same time

. We could, for example, look at age, gender, income and educational level in relation to walking and cholesterol levels, with little or no additional cost.
