What must be done to legitimize the use of indirect measurement?
A) The investigator must present clear experimental evidence about the relationship between what is being measured and what it is supposed to represent
B) The investigator must use the indirect measurement for an extended period of time in order to allow enough time for the intervention to demonstrate its effects
C) The investigator must repeatedly measure the target behavior using the indirect measurement
D) The investigator must use a large enough sample size to show that the results will generalize to other populations

Question

Quizplus · Accepted Answer

Indirect measurement can only be considered legitimate if there is clear experimental evidence that the measure is valid and reliable in representing the behavior or construct being measured. This evidence includes establishing a strong relationship between the indirect measure and the construct being measured through empirical research. Simply using the measure for an extended period of time, repeating measurements, or using a large sample size may not be sufficient to legitimize the use of indirect measurement without clear experimental evidence.
