The Color of Drinking Survey Questionnaire for Measuring the Secondhand Impacts of High-Risk Drinking in College Settings: Validation Study

The Color of Drinking Survey Questionnaire for Measuring the Secondhand Impacts of High-Risk Drinking in College Settings: Validation Study

The higher the coefficient, the stronger the test-retest reliability [13]. κ values between 0.41 and 0.6 were considered to be of moderate reliability, between 0.61 and 0.8 as substantial reliability and between 0.81 and 1 very high reliability [19]. κ is influenced by the trait prevalence and basal rates. κ may be low even though there are high levels of agreement and even though individual ratings are accurate, thus we have also calculated the proportion of observed and expected agreement only by chance.

Digital Ergonomics of NavegApp, a Novel Serious Game for Spatial Cognition Assessment: Content Validity and Usability Study

To account for the interrater chance of agreement, the modified κ statistic, based on the content validity index, was calculated [62]. This involved first computing the probability of chance agreement using the formula for a binomial random variable. The modified κ statistic was then derived using the proportion of agreements on relevance and the calculated probability of chance agreement [62]. Results were interpreted based on recommendations from the literature regarding the number of experts.
