In the present study both of these criteria were met, which can be seen from the high correlation between the indicator variables and scale development. The scale development was based mainly on modifying existing scales used in similar studies that were also conducted with LISREL. Even though the scale purifying can be considered valid, future studies should validate the findings by testing the model with other structural equation programs such as PLS (e.g., Chin 1998). Moreover, further work is required to develop the scaling procedure and to examine the impact of scale modifications on how well a modified scale performs in this new context under investigation (see e.g., Rossiter 2002).
