NP 801 In your own words, describe personal and research bias and explain why bias is one of the main reasons for poor validity in research outcomes
Great posting. Bias distorts the significance of the findings in the study in a systematic way which most times arises from the design method used. So, the researcher needs to be focused and alert because research can be introduced at any time in the study and also be aware of the different sources of possible bias. Sources like selection bias can affect who is placed in a particular group. This selection bias is reduced when researchers use random selection to place participants in groups (Melnyk, & Fineout-Overholt, 2018). Another source of bias is when the researcher knows who receives what intervention especially in randomized control trials. To minimize the bias reported from the author the authors should not be aware, it is called double blinded or triple blinded-when the person administering the intervention is not aware of who is in what group (Melnyk, & Fineout-Overholt, 2018). There are biases due to not following up with the participants especially when they drop out and not reporting it as such. There is also contamination bias. This is when the participants in the control group are exposed to the intervention of the experimental group (Melnyk, & Fineout-Overholt, 2018). There are also the cross-cultural measurement invariances that occur from with different cultural languages leading to culture bias, translation bias and comprehension bias. All these three are intertwined because there could be different cultural groups hence the culture, comprehension, and translation bias (CCT) procedure tools are used to minimize the bias. This allows for the dissociation of the three cultural biases (Bader, Jobst, Zettler, Hilbig, & Moshagen, 2021).
