2.6.2.1. Construct validity. Construct validity is
the extent to which we establish correct operational
measures for the concepts being studied (Kidder and
Judd, 1986). The journal article should describe how
data were collected via sources such as interviews,
questionnaires, company documents, and observations.
The second tactic is to establish a chain of
evidence. The paper should explain how someone
else could, beginning with the same raw data, derive
the same summary values for the various constructs
in the study. The third tactic for enhancing construct
validity is to have key informants review the draft
case study report.
