Document Summary

Epidemiological research helps us understand nature and disrtribution. Incidence rate = new cases per year or in another time period. Prevalence rate= all cases, whether new or previously existing that are observed during a specific time period. Risk factors: variable that precedes an outcome of interest and increases the chances that the outcome will occur. Protective factors: variable that precedes an outcome of interest and decreases the chances that the outcome will occur. Correlated variables: variables associated at a particular point in time with no clear proof that one precedes the other. Standardization: a set of norms is specified for a measurement procedure so that it can be used consistently across different assessments. Examples include same age, same socioeconomic status, and same gender. Reliability: consistency of a measure, either across raters or time. Validity: extent to which the method actually measures the construct of interest. Good tests will be all three of those!
