RESUMO
Resumen El coeficiente H evalúa la confiabilidad del constructo desde el enfoque SEM, dado que puede ser inadecuado el uso de los estimadores de confiabilidad habituales si no se cumplen algunos supuestos básicos. Para la demostración de la técnica se usó la información de cuatro estudios empíricos y se compararon los coeficientes de confiabilidad obtenidos (a, (0, y H). Del mismo modo, se analizó su aplicación en modelamiento bifactor. Finalmente, se discuten las ventajas, limitaciones y las condiciones para la apropiada aplicación de la técnica en el contexto de la validación de instrumentos de evaluación psicológica.
Abstract Index H evaluate the construct reliability from the SEM approach, since it may be inappropriate using usual reliability estimates if some basic assumptions are not met. To demonstrate the technique, was used information of four empirical studies and were compared the reliability coefficients obtained (a, (0 and H). Similarly, application in bifactor modeling was analyzed. Finally, the advantages, limitations and conditions for the proper application of the technique in the context of the validation of psychological assessment instruments are discussed.

Introducción: el Comité editorial de la Revista Cubana de Medicina Militar se ha sumado al monitoreo de los resultados publicados por el Scientific Journal Rankings, al evaluar procedencia y calidad de sus contribuciones con mayor impacto en SCOPUS y Google Académico. Objetivo: identificar las contribuciones individuales más importantes de la RCMM a los indicadores de impacto de esta publicación en los últimos 10 años. Métodos: se utilizó la bibliometría evaluativa para comparar los indicadores de visibilidad e impacto de la Revista Cubana de Medicina Militar, tales como índice H y factor de impacto, con respecto a otros títulos de publicaciones homólogas; mediante la adaptación alternativa de una metodología utilizada internacionalmente y que debe servir de mecanismo de alfabetización informacional a especialistas interesadas/os, así como de reconocimiento público. Resultados: de los 437 artículos, 149 trabajos (el 34 por ciento) han obtenido el impacto esperado; 84 contribuciones provienen de autores del Hospital Militar Central Luis Díaz Soto (56,4 por ciento) y 34 autores con 50 trabajos (35,5 por ciento) el HMC Dr. Carlos J. Finlay; el 14,1 por ciento de las contribuciones con citaciones (21) se publicaron con colaboración institucional, provenientes del 14,1 por ciento del total de autores/as, donde predominaron 7 autoras principales de 9 en total. Conclusiones: se identificaron como factores de éxito para los 149 artículos originales publicados en la Revista Cubana de Medicina Militar los artículos provenientes de hombres investigadores de los hospitales militares centrales Dr. Luis Díaz Soto y Dr. Carlos J. Finlay, del total de 90 autores principales que lideraron la Revista Cubana de Medicina Militar(AU)
Introduction: The editorial committee of the Cuban Journal of Military Medicine (RCMM) has joined the monitoring of results published by the Scientific Journal Rankings, when assessing the source and quality of their contributions with greater impact in SCOPUS and Google Scholar (GS). Objective: Identify the most important individual contributions of the RCMM to the impact indicators of this publication in the last 10 years. Methods: Assessing bibliometry was used to compare RCMM indicators of visibility and impact, such as H index and impact factor, with respect to other titles of homologous publications; through the alternative adaptation of a methodology used worldwide and that should serve as a mechanism for information literacy to interested specialists, as well as public recognition. Results: Out of 437 articles, 149 papers (34 percent) have obtained the expected impact. 84 contributions are by authors of Luis Díaz Soto Central Military Hospital (56.4 percent), and 50 papers (35.5 percent) by 34 authors from Dr. Carlos J. Finlay HMC. 14.1 percent of the contributions with citations (21) were published with institutional collaboration, from 14.1 percent of the total number of female authors. There were 7 main authors who predominated out of 9. Conclusions: The articles by male researchers of Dr. Luis Díaz Soto and Dr. Carlos J. Finlay central military hospitals were identified as success factors for the 149 original articles published in the RCMM, out of a total of 90 authors who ranked RCMM(AU)

A new scientometric indicator, the h-index, has been recently proposed (Hirsch JE. Proc Natl Acad Sci 2005; 102: 16569-16572). The index avoids some shortcomings of the calculation of the total number of citations as a parameter to evaluate scientific performance. Although it has become known only recently, it has had widespread acceptance. A comparison of the average h-index of members of the Brazilian Academy of Sciences (BAS) and of the National Academy of Sciences of the USA (NAS-USA) was carried out for 10 different areas of science. Although, as expected, the comparison was unfavorable to the members of the BAS, the imbalance was distinct in different areas. Since these two academies represent, to a significant extent, the science of top quality produced in each country, the comparison allows the identification of the areas in Brazil that are closer to the international stakeholders of scientific excellence. The areas of Physics and Mathematics stand out in this context. The heterogeneity of the h-index in the different areas, estimated by the median dispersion of the index, is significantly higher in the BAS than in the NAS-USA. No elements have been collected in the present study to provide an explanation for this fact.
