The Learning Transfer System Inventory (LTSI) was developed to identify a select set of factors with the potential to substantially enhance or inhibit transfer of learning to the work environment. It has undergone a variety of validation studies, including construct, criterion, and crosscultural studies. However, the convergent and divergent validity of the instrument has not been studied. Such a study is necessary to define the nomological network on the constructs. This study examines the convergent and divergent validity of the LTSI with twenty-eight comparison measures. Results indicate mostly divergent relationships, further demonstrating the uniqueness of the LTSI constructs. By establishing the divergent relationship with other known constructs, the LTSI's usefulness for transfer research is enhanced.In 1996, Holton and Bates developed the learning transfer system inventory (LTSI) as a generalized transfer climate instrument that could be used across a wide variety of organizations, training programs, and employees. The LTSI, based on evaluation theory, was developed by examining relationships and constructs from previous empirical research in a grounded theory-building approach (Holton, 1996). Holton, Bates, and Ruona (2000) indicated that "without minimally validated measures, the chance for substantive misspecification of models, misinterpretation of findings and measurement error is significantly increased" (p. 6).Most human resource development (HRD) professionals realize that their organizations need learning transfer improvement, but few have an accurate sense of what the problem is. As a result, even those aware of strategies to improve transfer (Broad & Newstrom, 1992) Holton, Bates, Bookter, Yamkovenko guesswork to guide them to those most likely to yield high returns. Yet most would agree that improving learning transfer systems requires an ability to accurately diagnose factors inhibiting transfer.The primary reason for this paradox is that until recently, no diagnostic tool had emerged. In recent transfer research, a wide variety of instruments and measures have been used, most with either questionable or unknown psychometric properties. As a result, neither practitioners nor researchers have had a well-validated, effective diagnostic instrument. This presents a key barrier because it is hard to change a transfer system without accurate diagnosis of system problems.The lack of a comprehensive set of factors to measure learning transfer climate, which are generalizable to a wide variety of organizations and employees, is an issue that research should continue to address. The development of a generalized set of transfer factors would facilitate cross-study comparison and eliminate redundant instrument development efforts .Ford and Weissbein (1997) conducted a review of empirical literature on transfer of training that updated the earlier Baldwin and Ford (1988) study. Their study indicated a continuing problem with instrumentation in transfer research. For example, nine of the studies identifie...
