PROSPECTIVE RESEARCH: "The prospective research required five adolescents on the first day of school and followed them through spring break." There are only two ways to collect data for a retrospective study: either the investigator collects information from written evidence like from books, magazines, newspapers, diaries and other personal records, or he asks the respondents who can recall the situation. In medical studies, researchers use this design to examine exposures to already presumed risk factors concerning already experienced outcomes by the start of a study. การออกแบบการวิจัย (research design) เป็นการวางโครงสร้างเฉพาะ (structure) ของการวิจัยและเป็นการวางแนวทางใน The design of the study (such as a case report for an individual patient or a blinded randomized controlled trial) and the endpoints measured (such as survival or quality of life) affect the strength of the evidence. In section 2, through familiar examples within psychological research, the benefits of prospective and retrospective design analysis will be highlighted. Prospective study design is the best design for establishing relationships between your outcome of interest and exposure variables. When considering research, design is often determined by the researcher’s theoretical perspective whereas the method of data collection typically follows from the question of interest in a particular study. Experimental studies provide the best evidence about how something affects something else, and double-blind randomized controlled trials are the best experiments. It involves the use of different data collection and data analysis techniques logically to answer the research questions.. To conduct a prospective design analysis considering a correlation between two variables, we need to specify test_method = "pearson" (default option). Technology Research: Prologue, Present, and Prospective. Most of the studies that are conducted using the prospective study design are also classified as experimental studies since the aim of the investigator is to wait for the impact of a program or a situation to see the results on the target population.

Expert area knowledge is required to interpret qualitative data. It has the benefit that researchers can design the study to answer specific questions and hypotheses rather than relying on data collected for similar but not necessarily identical purposes. Prospective causal-comparative research – This method begins with studying the causes and is progressed by investigating the possible effects of a condition. In Research 101: Levels of Evidence, we discussed criteria that determines the value of a clinical study.Here we will discuss how the initial trial design can dictate the strength of a study..

A prospective cohort study is a longitudinal cohort study that follows over time a group of similar individuals who differ with respect to certain factors under study, to determine how these factors affect rates of a certain outcome. The article advances a prospective case study design in social sciences as an alternative to traditional post hoc case study research in deductive theory testing. Often these studies are the only practicable method of studying various problems, for example, studies of aetiology, instances where a randomised controlled trial might be unethical, or if the condition to be studied is rare. Prospective cohort studies are the only practical research design to investigate the long-term relationship between diet and disease, particularly with the preponderance of current evidence in nutrition indicating that whole diet patterns are more informative of diet-disease relationships than any isolated food or nutrient (11,12). This design feature allows the investigator to measure predictor variables more accurately and completely than is possible using retrospective design and prevents the predictor measurements from being influenced (e.g., biased) by knowledge of outcome status. What is Descriptive Research? NO. In epidemiology, such designs are often called cohort studies. Experimental studies are definitive about how something affects something else, and with far fewer subjects than descriptive studies!
