These biases are prevalent in research involving participant self-report, such as structured interviews or surveys ...

Recall bias is of particular concern in retrospective studies that use a case-control design to investigate the etiology of a disease or psychiatric condition. [ 3 ] [ 4 ] [ 5 ] For example, in studies of risk factors for breast cancer , women who have had the disease may search their memories more thoroughly than members of the unaffected ...
Spectrum bias arises from evaluating diagnostic tests on biased patient samples, leading to an overestimate of the sensitivity and specificity of the test. For example, a high prevalence of disease in a study population increases positive predictive values, which will cause a bias between the prediction values and the real ones. [4]
Acquiescence bias, also known as agreement bias, [1] is a category of response bias common to survey research [2] in which respondents have a tendency to select a positive response option [1] [3] or indicate a positive connotation disproportionately more frequently.
A meta-analysis of 30 methodological studies on non-response bias by Robert M. Groves found that the coefficient of determination for variance in non-response bias by response rate was only 0.11, making it a weak predictor of non-response bias. Another meta-analysis of 44 methodological studies similarly found that methods that resulted in ...
Non-response bias: When individuals or households selected in the survey sample cannot or will not complete the survey there is the potential for bias to result from this non-response. Nonresponse bias occurs when the observed value deviates from the population parameter due to differences between respondents and nonrespondents. [12] Response ...
