Based on recent psychometric developments, this paper presents a conceptual and practical guide for estimating internal consistency reliability of measures obtained as item sum or mean. The internal consistency reliability coefficient is presented as a by-product of the measurement model underlying the item responses. A three-step procedure is proposed for its estimation, including descriptive data analysis, test of relevant measurement models, and computation of internal consistency coefficient and its confidence interval. Provided formulas include: (a) Cronbach’s alpha and omega coefficients for unidimensional measures with quantitative item response scales, (b) coefficients ordinal omega, ordinal alpha and nonlinear reliability for unidimensional measures with dichotomic and ordinal items, (c) coefficients omega and omega hierarchical for essentially unidimensional scales presenting method effects. The procedure is generalized to weighted sum measures, multidimensional scales, complex designs with multilevel and/or missing data and to scale development. Four illustrative numerical examples are fully explained and the data and the R syntax are provided.

This research observes the relationship between Latin American (LA) journalists from six countries that are rarely observed by international scholars (Bolivia, Brazil, Colombia, Cuba, Peru and Venezuela) and artificial intelligence (AI). Particularly, it seeks to identify and compare their attitudes, perceived constraints, and knowledge on the state of the art of the application of AI to professional journalistic practices. In tune with the quantitative turn in contemporary journalism and due to the lack of quantitative measures in this field, this research also develops and psychometrically validates tools for measuring such aspects. The main results reveal the existence of differences in these journalists’ attitudes and knowledge with regard to AI that can be attributed to their cultural context. They also show similarities to attitudes of journalists from Northern countries to AI. This research fills in the gap in the existing literature on journalism, AI, journalists’ attitudes, Global South and LA journalism.

This cross-cultural descriptive empirical research observes the relationship of 937 high-school students from eight countries of the European Union with cinema. A survey was applied in 37 schools and 28 cities for individuals participating in a course on film literacy that was offered free of charge and as an extracurricular opportunity in their educational centres. The statistical analysis of the responses shows patterns perhaps tied to the respondents’ culture (country) in their motivation for going to the cinema, their film-choice preferences, the media they watch the films on, the ways they select and obtain the films they watch, the frequency with which they download films and their preferred genres. However, there are also common patterns of use and consumption across the European adolescents in the sample. The results of this research are useful for understanding the place that cinema occupies in the life of youngsters today and particularly relevant for audiovisual regulators, who, they, should take into account the cultural characteristics of young audiences if their actions are to bear fruit.
