Purpose: The aim in the present study was to illustrate generalizability theory by exploring some psychometric aspects of the Norwegian version of KINDL (KINDL-N). This questionnaire is a measure of quality of life in adolescents. It consists of 24 items arranged in six subscales or aspects, corresponding to six domains of adolescents' health-related quality of life.
Method: A total of 239 healthy adolescents completed the questionnaire. The analysis was performed in line with generalization theory, and this analysis yields among other things so-called generalizability and dependability coefficients, which are analogous to reliability coefficients in classical test theory. The preferred design was a mixed two-facet design, with the six aspects as a fixed facet and the items nested within aspects as a random facet. For comparison, a random two-facet design and a one-facet design were also analyzed.
Results: The generalizability and dependability coefficients for KINDL-N are satisfactory, but the coefficients can be markedly improved by increasing the length of the instrument while keeping it to a manageable size. The mixed two-facet design resulted in somewhat higher coefficients than a one-facet design and much higher coefficients than a random two-facet design.
Conclusion: If the items within a questionnaire are arranged in distinct subscales, a two-facet design analyzed by generalizability theory gives more sophisticated results than classical test theory. Moreover, the results may depend considerably on whether a mixed or random two-facet design is chosen. Hence, the choice of an appropriate measurement design in line with the intended use of the questionnaire is essential.

The Stroke Riskometer mobile application is a novel, validated way to provide personalized stroke risk assessment for individuals and motivate them to reduce their risks. Although this app is being used worldwide, its reliability across different countries has not yet been rigorously investigated using appropriate methodology. The Generalizability Theory (G-Theory) is an advanced statistical method suitable for examining reliability and generalizability of assessment scores across different samples, cultural and other contexts and for evaluating sources of measurement errors.

Purpose: We have previously developed an instrument for students' evaluation of clinical teachers that we called Visual Indicators of Clinical Teaching and Learning Success (VITALS). This study measures the reliability of VITALS as an instrument for student evaluation of clinical tutors. Additionally, the study explores the minimum number of student raters necessary for an acceptable reliability, and provides evidence of construct validity of the evaluation scores.

In many behavioral research areas, multivariate generalizability theory (mG theory) has been typically used to investigate the reliability of certain multidimensional assessments. However, traditional mG-theory estimation-namely, using frequentist approaches-has limits, leading researchers to fail to take full advantage of the information that mG theory can offer regarding the reliability of measurements. Alternatively, Bayesian methods provide more information than frequentist approaches can offer.

Obesity and dyslipidemia is the two facet of metabolic syndrome, which needs further attention. Recent studies indicate triazole and indole derivatives have remarkable anti-obesity/antidyslipidemic activity. To harness the above-mentioned potential, a series of novel triazole clubbed indole derivatives were prepared using click chemistry and evaluated for anti-adipogenic activity.
