In epidemiology does a cohort study require a control group?
In epidemiology, a cohort study does not necessarily require a control group, as it primarily focuses on following a group of individuals (the cohort) exposed to a certain risk factor or intervention over time to observe outcomes. However, including a comparison group can enhance the study's validity by providing a benchmark for evaluating the effects of the exposure. Without a control group, it may be more challenging to attribute observed outcomes directly to the exposure. Ultimately, the design choice depends on the study's objectives and context.

What are cohort and time of measurement effects in developmental research designs?
A cohort is a sample of people that are all born at about the same time. For instance, everyone that you are studying are born in 1940. Time measurement effects mean when the time you measure something effects your dependent variable.
What is an inception cohort study?
An inception cohort study is a type of observational research design that follows a group of individuals who are newly diagnosed with a specific condition or disease over time. Participants are enrolled at the point of diagnosis or disease onset, allowing researchers to assess the natural progression of the condition and the effects of various exposures or treatments. This design is particularly useful for understanding the early stages of a disease and identifying potential risk factors or outcomes associated with it.

What is an cohort study?
A cohort study is a type of research design where a group of individuals sharing a common characteristic are followed over a period of time to observe outcomes. By comparing outcomes between the exposed and unexposed groups, researchers can assess the impact of the particular characteristic on the outcomes of interest. This study design is frequently used in epidemiology to investigate the causes of diseases.
