be introduced differential selection or retention in a study. The converse ease of recall bias examples is also true: even if the selection and retention into the study is a fair representation recall bias in qualitative research of the population from which the samples were drawn, the estimate of association can be biased if subjects are incorrectly categorized with respect to their exposure status https://en.wikipedia.org/wiki/Recall_bias or outcome. These errors are often referred to as misclassification, and the mechanism that produces these errors can result in either non-differential or differential misclassification. Ken Rothman distinguishes these as follows: "For exposure misclassification, the misclassification is nondifferential if it is unrelated to the occurrence or presence of disease; if the misclassification of exposure is http://sphweb.bumc.bu.edu/otlt/MPH-Modules/EP/EP713_Bias/EP713_Bias4.html different for those with and without disease, it is differential. Similarly, misclassification of disease [outcome] is nondifferential if it is unrelated to the exposure; otherwise, it is differential." Nondifferential Misclassification of Exposure Nondifferential misclassification means that the frequency of errors is approximately the same in the groups being compared. Misclassification of exposure status is more of a problem than misclassification of outcome (as explained on page 6), but a study may be biased by misclassification of either exposure status, or outcome status, or both. Nondifferential misclassification of a dichotomous exposure occurs when errors in classification occur to the same degree regardless of outcome. Nondifferential misclassification of exposure is a much more pervasive problem than differential misclassification (in which errors occur with greater frequency in one of the study groups). The figure below illustrates a hypothetical study in which all subjects are correctly classified with respect to outcome, but some of the exposed subjects in each outcome group were incorrectly classified as 'non-exposed.'

The authors conducted a validation substudy within the framework of a parent case-control study on risk factors for acute lymphoblastic leukemia in children aged ≤9 years diagnosed in 1980–1993 in Québec, Canada. Parental recall bias for two variables was assessed: reported distance from home to recall bias in power lines compared with measured distance and reported prenatal radiographic examinations compared with hospital medical record data. For reported distance, sensitivity was 62% for a subgroup of cases living in an area in which an excess of childhood acute lymphoblastic leukemia was perceived and was attributed to power lines. However, for other cases, sensitivity (35%) was similar to that measured for hospital controls (36%) and was relatively close to that for population controls (22%). Specificity was high for all groups except cases from the area with a perceived excess. Sensitivity for reported prenatal radiographic examinations was similar for cases (64%) and population controls (71%) but was lower for hospital controls (50%). Results confirm that under special circumstances, such as those resulting from enhanced public concern, parental recall can be differential but otherwise is most often nondifferential, with low sensitivity. Choosing the best type of controls to ensure comparable recall accuracy remains difficult. Am J Epidemiol 2000;152:480–6.

Information (Measurement) Bias Articles - Wiki Rate This Information (or measurement) biasrefers to a systematic error in the measurement or classification of participants in a study [1]. It occurs when the accuracy of information collected about or from study participants is not equal between cases and controls (i.e. differences in accuracy of exposure data), or, between exposed and unexposed (i.e. differences in accuracy of outcome data). Lack of accuracy could mean that study subjects are assigned into the wrong category of exposure (exposed/unexposed) or outcome (case/control), or both. All attempts should be made to minimise or prevent information bias. The term "misclassification" is frequently used to describe this bias. Cases and controls can be misclassified. Exposed and unexposed as well e.g. a heavy smoker who is categorised as a light smoker is misclassified. Misclassification results in an incorrect estimation of the association between exposure and outcome, the size and directio
