Overall, our results support the behavioral validity of the strategy method in public good experiments.
In our context, however, we can be confident about the behavioral validity of the survey measures, because the particular set of questions has reliably predicted actual risk taking behavior in a large-scale, incentive compatible lottery experiment with real money at stake (Dohmen et al. 2011).
However, ensuring behavioral validity of reused process models with respect to the original process models (often referred to as reference process models) is still an open research challenge.
However, researchers are cautioned, at this time, to interpret these data carefully, since the exact significance of the behaviors is not fully understood and little empirical evidence is available to support the validity of the behavioral measures in the open tank [28] [31].
Hence, in order to determine the external validity of the behavioral phenotypes while at the same time revealing biologically relevant interactions [34], [35], we intended to pursue our research objective with a 2×2 factorial design [36].
Baiting of both the novel and familiar objects was designed to encourage the rats' exploration of the test objects, but could not affect the validity of the behavioral test, which relied on the differential exploration of both objects.
This arrangement motivated the rats to approach the objects, but did not affect the validity of the behavioral test of recognition, which relied on differential levels of exploration between the two baited objects.
This feature ensured the rats' continued approach to the objects, but did not affect the validity of the behavioral test of recognition as this relied on differential object exploration.
Cummings et al 2 reported that, because there is no gold standard for comparison for the domains of disinhibition, euphoria, apathy, and irritability, they submitted the NPI to a panel of ten experts in neuropsychology, geriatric psychiatry, and behavioral neurology, and obtained the face validity of the instrument using the Delphi process.
In addition, ratings on the DISC were significantly correlated with scores on the SDQ, thus indicating the predictive validity of the DISC for behavioral problems.
In addition, ratings on the DISC were significantly correlated with scores of the Strengths and Difficulties Questionnaire (SDQ; Goodman, 1997), indicating predictive validity of the DISC for behavioral problems.
