Construct validity depends on adequate definition and measurement of constructs.The conceptual definition should emerge from the concept analysis and the operational definition should clearly reflect both.Allowing data collectors to know which subjects are assigned to which groups and involving the researcher in data collection both increase the risk of bias.Using only one measurement tool increases the risk of mono-operation bias.
