The research process is described as the interrelationships of conceptual, methodological, and substantive domains. The specification of each domain and their interrelations will be discussed. Traditional forms of validity will be presented within the proposed framework and new forms of validity researchers need to consider will also be derived from this framework. As the reader is aware, the concept of validity has taken many forms and meanings to describe different components of the research process. For instance, construct validity, convergent, and discriminant validity for theoretical variables; internal validity for research design; statistical conclusion validity for data analysis; and external validity for the robustness of research findings. Give the current state of the art concerning the various forms and meanings of validity issues, several options seem available to researchers. One option would involve further refinement and specification of current validity concepts.

Experimentation in the 21st century: The importance of external validity

Much of the consumer behavior literature is devored to what has been referred to as theory applications TA research in which the main focus is on laboratory experiments with student subjects and high internal validity. In this articlee, the author argues that external validity concerns should be given more attention, particulary in TA research. Three examples are given from the marketing literature of how findings from experiments and scanner data can be combined to advance a stream of research.

Given the experimental nature of this study, a student sample was used with the objective of increasing its internal validity (Brinberg and McGrath.


Validity Concepts in Research: an Integrative Approach

Beware: business history is littered with stories about smart companies that hemorrhaged multiple millions from ventures gone bad.

Protecting Respondent Confidentiality in Qualitative Research

Although the importance of validity has long been accepted among quantitative researchers, this concept has been an issue of contention among qualitative researchers. Thus, the first purpose of the present paper is to introduce the Qualitative Legitimation Model , which attempts to integrate many of the types of validity identified by qualitative researchers. The second purpose of this article is to describe 24 methods for assessing the truth value of qualitative research. Utilizing and documenting such techniques should prevent validity and qualitative research from being seen as an oxymoron. This is a preview of subscription content, access via your institution.

The proportion of ventures that are actually launched is low, and the costs of not just the failures but also the successes all too often dwarf original estimates. Indeed, some studies have found that a firm typically has […]. The high failure rate among new business ventures is usually chalked up to the fundamental uncertainty of the process. In actuality, say McGrath and Keil, flawed ways of assessing and managing ventures may account for the disappointing amount of value they generate.

For qualitative researchers, maintaining respondent confidentiality while presenting rich, detailed accounts of social life presents unique challenges. These challenges are not adequately addressed in the literature on research ethics and research methods. Deductive disclosure, also known as internal confidentiality Tolich, , occurs when the traits of individuals or groups make them identifiable in research reports Sieber, For example, if a researcher studying teachers named the school district where the research occurred, someone with knowledge of the school district could likely identify individual teachers based on traits such as age, gender, and number of years with the school district Sieber, Given that qualitative studies often contain rich descriptions of study participants, confidentiality breaches via deductive disclosure are of particular concern to qualitative researchers. As such, qualitative researchers face a conflict between conveying detailed, accurate accounts of the social world and protecting the identities of the individuals who participated in their research.

Measures of psychological constructs are validated by testing whether they relate to measures of other constructs as specified by theory. Each test of relations between measures reflects on the validity of both the measures and the theory driving the test. Construct validation concerns the simultaneous process of measure and theory validation. In this chapter, we review the recent history of validation efforts in clinical psychological science that has led to this perspective, and we review five recent advances in validation theory and methodology of importance for clinical researchers. These are: the emergence of nonjustificationist philosophy of science; an increasing appreciation for theory and the need for informative tests of construct validity; valid construct representation in experimental psychopathology; the need to avoid representing multidimensional constructs with a single score; and the emergence of effective new statistical tools for the evaluation of convergent and discriminant validity.
