To calculate the validity and reliability of a questionnaire to measure the quality of life in post-menopausal women.
We did not use a common database to calculate the validity, sensitivity, or specificity of the ICHD-3 beta criteria.
One method for calculating the validity of a screening instrument which takes into account ASD prevalence is Bayes Theorem.
Because psychiatrists diagnosed only one participant with MinD and only one participant with SSD, it was not possible to calculate the validity for MinD and SSD.
On the basis of the results given by ROC curves, the best discriminatory value was used to calculate the validity of the MCE parameters in correctly identifying treated and control animals.
To calculate the validity effect and the right hemifield disadvantage, RTs for correct responses for each cycle phase were subjected to a 2×2 ANOVA (Greenhouse-Geisser) with factors validity (valid, invalid) and visual hemifield (left, right).
We also calculated the concomitant validity by considering only the questionnaires with complete data at T1 and T2 and obtained similar results (N = 66 (r = 0.45, 95% CI: 0.23 - 0.62, p < 0.01) and at T2 (r = 0.54, 95% CI: 0.34 - 0.69, p < 0.01).
Third, using a DSM-IV-TR criterion-defined delirium as gold standard, we used sensitivities (SE), specificities (SP), positive and negative predictive values (PPV and NPV respectively) and their confidence intervals and calculated the concurrent validity of each RADAR item and the RADAR scale as a whole.
We also calculated the standards association validity coefficient, Cronbach's alpha coefficient, split-half coefficient, paired t-test, SES, SRM respectively in these two subgroups.
First univariate linear regression was applied to y and x, and then Cook's distance was calculated to estimate the validity of the data points.
