AMU Week 5 Cross Sectional and Longitudinal Study Discussion

AMU Week 5 Cross Sectional and Longitudinal Study Discussion AMU Week 5 Cross Sectional and Longitudinal Study Discussion ORDER NOW FOR CUSTOMIZED AND ORIGINAL NURSING PAPERS I need support with this Psychology question so I can learn better. For this week’s discussion, complete these tasks: Explain three circumstances where a researcher would choose a longitudinal study over a cross-sectional study. Identify two advantages and two disadvantages of a longitudinal study and a cross-sectional study, giving examples of each. Then, provide a specific example of a question that could be addressed with a longitudinal study and explain why that developmental design is preferred.

If you had midterms I hope everyone did great. This week lesson discusses to different types of studies.This weeks studies are cross sectional study and longitudinal study. The first study I will be focusing on is longitudinal study. This study is based over prolonged periods of time . This study is generally observation based. The study would be good for a question as stated : how do the affects of smoking over the years promote lung cancer? This design would be preferred because you could watch someone over the years to see if they developed lung cancer and the different effects it had or didn’t have. The advantages of a longitudinal study are the longevity of the study and the ability to collect more information. The amount of time the study takes and the amount of people the study. For example the study for my question could be over the course of decades and they may never get cancer. The amount of people can be hard to monitor and this can make it difficult for reliable information. For example this many people could alter the study and especially if they end up changing their habits. The good majority may quit smoking. The next study is cross sectional study. This is when you focus on data from one specific time point. The advantages are they’re more cost effective and quicker. For example you could do this in a form of a survey and get straight answers at this moment about them smoking. This would give you your data right then and there. The disadvantages of this study is you wouldn’t be able to get a accurate cause and effect. For example the individuals in the study would only be able to give what they thought may be the cause. There would be no exact reliable proof with just the survey. If you were watching them in the longitudinal study this could be answered potentially. In the circumstances of watching a change in behaviors cross sectional would be a good way to go . They could see what happened to the individuals that stop smoking or kept smoking and see how it affected their behaviors. They may want a cause and affect . For example what caused the individual to stop smoking and what were the affects after. They may want to see this in large or small population . This study can help you to scope out the proper individuals for this study for more reliable information. AMU Week 5 Cross Sectional and Longitudinal Study Discussion. I hope I answered the discussion well. I look forward to reading your responses. Thank you for reading! -Antoinette Work cited Caruana, E. J., Roman, M., Hernández-Sánchez, J., & Solli, P. (2015, November). Longitudinal studies. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4669300/ Response #2 Explain three circumstances where a researcher would choose a longitudinal study over a cross-sectional study. A longitudinal study is a study that is conducted over a long period of time, while a cross-sectional study may study multiple variables but does not provide information on how time may affect these variables (Caruana, Roman, Hernández-Sánchez, & Solli, 2015). There are many circumstances in which a researcher would choose a longitudinal study over a cross-sectional study. For example, a researcher conducting a study on the long term effects of medication on patients would need to conduct a longitudinal study rather than a cross-sectional study. Patients would need to be followed over a long period of time in order to gather the required information. A longitudinal study would also be more appropriate than a cross-sectional study if multiple cross-sectional studies with different participants each time need to be conducted (Caruana, et al., 2015). A longitudinal study would be a better fit for studies needing to be done retrospectively. Especially if only part of the participants have experienced relevant events (Caruana, et al., 2015). Identify two advantages and two disadvantages of a longitudinal study and a cross-sectional study, giving examples of each. Longitudinal studies are conducted over a long period of time allowing for the measurement of the effect of time on variables such as in a study on the effects of medication on patients. However, the long period of time needed for this type of study means that over time participants may drop out of the study or not follow up with the needed data. Another advantage of longitudinal studies is the reduction of recall bias. Data is collected about participants’ current circumstances or from a short period of time. Longitudinal studies tend to be more expensive and time-consuming due to the longer period of time needed to complete the study. Cross-sectional studies can be done quickly and inexpensively. For example, cross-sectional studies can be done using simple questionnaires. One disadvantage of this type of study is that questionnaires tend to have a low response rate. Cross-sectional studies are also more susceptible to bias due to lower response rates. Another advantage of cross-sectional studies is that the data is only collected once. This makes for less work for the researcher. Provide a specific example of a question that could be addressed with a longitudinal study and explain why that developmental design is preferred. What are the long term effects of illicit drug use during pregnancy on the child? A longitudinal study would be needed in order to track the effects of the mother’s illicit drug use over a long period of time. Jessica Wright Reference Caruana, E. J., Roman, M., Hernández-Sánchez, J., & Solli, P. (2015). Longitudinal studies. Journal of thoracic disease, 7(11), E537–E540. https://doi.org/10.3978/j.issn.2072-1439.2015.10.63 Response #3 When looking into longitudinal studies I noticed a few instances where this type of study may be more beneficial, of course depending on the type of study. A longitudinal study is observing the same variable multiple times over a certain period of time. This type of study is more likely to produce reliable data. When your data is tested multiple times and you get the same result, this data is more accurate and reliable than just testing it once. This type of study would also be able to detect any trends for a particular type of research. When studying something multiple times you are able to see if there are any trends that arise. A disadvantage to this study though would be that it definitely takes longer to complete this type of study over a cross-sectional study. It would also cost more money and more resources to be able to test your hypothesis multiple times. A cross-sectional study is very different in two ways. Instead of researching one topic it researches many and instead of doing the same study multiple times, it studies multiple topics one time. This can be beneficial when it comes to time and resources. Like I mentioned before longitudinal studies take more time and more resources making it expensive. With the cross-sectional you can study multiple topics at once. Cross sectional studies can be better to use when you need to know information for a specific time period. Using longitudinal studies can show progress of a study over time, but when that is not needed you can use cross-sectional to get current data. Cross-sectional can also be great in order to gather current data from multiple sources at one time. The disadvantages to this study is you cannot use this to monitor anything that needs to be watched overtime. Like development, behavior, cause and effect, or trends of any kind. -Abby Get a 10 % discount on an order above $ 100 Use the following coupon code : NURSING10
