We argue in this chapter that quantitative techniques alone cannot enable appropriate verification of the levels in which a construct should be defined and validated. We propose a process model that takes advantage of qualitative and quantitative methods when specifying and measuring the level(s) of analysis in construct development. The model implies that operationalizing a construct and its measurement should involve both qualitative and quantitative methods. Level specification begins with induction of constructs and continues with qualitative or quantitative operationalizations that are verified through the convergence of using triangulation and aggregation tests. Construct development continues until the level of analysis is accurately specified. We provide a theoretical example of construct development from the leadership literature and an empirical example to represent the verification process.
