The method for calculating the content validity ratios (CVR),developed by Lawshe (1975) is described by the formula: CVR¼(ne-N/2)/(N/2); where CVR is the content validity ratio, ne is thenumber of panelists indicating essential about a specific questionand N is the total number of panelists. The CVR of each scale item was calculated as a means of quantifying the degree of consensus in the above-mentioned thirteen panelists, who made judgments about the instrument's content validity. Each expert was asked to judge whether or not the 31 questions in the initial instrument list were indeed essential in measuring the constructs included in our conceptual framework. According to Lawshe's criteria for CVR (Lawshe, 1975), the minimum CVR value of 0.56 needs to be met for statistical significance (p < 0.05). The feedback from the pilot respondents resulted in minor modifications to the wording of 28 survey items, and an endorsement of the model, instrument completeness and item association with dimensions.
