With
regard to the quantitative approach, the survey instrument for measuring the
enabling conditions espoused by the theory fell short of our intended objective
for both reliable and valid measurement. Psychometrically, the instrument
revealed good internal reliability, though its validity was not established in
the hypothesis testing
An Empirical Test of Nonaka's Theory of Organizational Knowledge - 0 views

There are two possible interpretations of this particular finding: either the theory is invalid, or our test of the theory was not sufficient. It is our belief that the lack of association between our measure of knowledge enabling constructs and compliance with guidelines is in no way an indictment of the theory, rather an issue of measurement. There are several potential explanations for its inability to validly predict performance. According to Hunter and Schmidt (1990), measurement error in either the predictor or the criterion spuriously lowers ability to detect effect sizes.

With regard to our measure of performance (i.e., EPRP data), there is reason to question its accuracy in terms of documentation. Anecdotally, we were told that EPRP data does not necessarily reflect the true state of affairs in reference to guideline adherence. For example, performance may actually occur even though it is not formally documented (e.g., conducting depression screening, though neglecting to record this activity). Conversely, providers admitted to documenting performance that may not have actually occurred (e.g., offering smoking cessation counseling when none was actually given). Because our outcome data may have suffered from documentation errors, the actual effect of knowledge creation on guideline compliance may not have been realized. Also, statistical power was not sufficient to detect potentially meaningful effects. Saal and Knight (1996) recommend a 10:1 case to predictor ratio for estimating statistical power for collection of predictor data. A 31-item instrument would therefore require 310 cases or respondents to yield sufficient power, clearly more than we were able to acquire. Finally, this research must be quantitatively regarded as pilot work toward the development of a survey instrument. Indeed, survey development is an iterative process in which this project was the first iteration.
