A researcher conducts a quasi-experimental study to determine whether there is appropriate weight gain among premature infants who are fed according to cue-based protocols.The researcher trained neonatal intensive care nurses to apply cue-based feeding to orally fed infants and notes a statistical difference in weight gain between infants fed according to cue-based protocols and those fed according to standard protocols.The reviewer critiquing the study notes that not all nurses completed the cue-based feeding module.This would affect which type of validity?
A) Construct validity
B) External validity
C) Internal validity
D) Statistical conclusion validity

Statistical conclusion validity is concerned with whether the conclusions based on statistical analyses are an accurate reflection of the real world.This can be threatened by anything interfering with consistent implementation of a variable,including inadequate training of individuals who implement the intervention.Construct validity is concerned with the fit between conceptual and operational variables and requires adequate conceptual and operational definitions.External validity is concerned with the extent to which findings can be generalized beyond the study sample.Internal validity looks at the influence of extraneous variables on study outcomes.
