Validity, in essence, has got to do with the extent to which a given research study measures the accuracy of a specific concept – effectively meaning that a study can be said to have passed the validity test if it accurately mirrors that which the researchers set about to investigate. In quantitative research, as Polit and Beck (2012) point out, “researchers strive to design studies that are strong with respect to all four types of study validity” (p. 303). As the authors further point out, while an attempt to enhance one kind of validity may benefit another form of validity, efforts to ensure one kind of validity sometimes end up interfering with the achievement of other validity types. The four kinds of validity to be taken into consideration in the review of a research design are identified as external validity, internal validity, construct validity, and statistical conclusion validity (Balnaves and Caputi, 2001).Internal validity is often been cited as being of utmost importance in research (Polit and Beck, 2012). For a qualitative research to be regarded beneficial and relevant,it has to clearly define or demonstrate cause and effect. In the absence of internal validity, the said case and effect relationship would be weak and therefore,...
