ABSTRACT

Resumen Este trabajo abordar una reflexión sobre el impacto de la pandemia COVID19 sobre la salud mental de los trabajadores, y en particular, sobre las condiciones del teletrabajo. Para ello se recupera y analiza diferentes documentos de organismos internacionales y diferentes publicaciones científicas especializadas. De la información recuperada se señala que la pandemia no sólo ha tenido importantes efectos sobre la salud mental de los trabajadores de primera línea, sino también, sobre los trabajadores que debieron migrar repentinamente hacia los entornos virtuales, sin demasiada organización previa. No obstante, un aspecto positivo se refleja en la organización de diferentes dispositivos de atención de la salud mental remota, implementados para la atención de poblaciones vulnerables, trabajadores de primera línea y población general. Se concluye enfatizando la importancia del desarrollo de políticas públicas para la atención específica de la salud mental de los trabajadores.


Abstract This review addresses the impact of the COVID-19 pandemic on workers' mental health, in particular, teleworking conditions. Our analysis is based on documents from several international organizations and specialized scientific publications. The retrieved information reveals that the pandemic has had a significant effect on the mental health of frontline workers and employees who had to migrate to a virtual environment without prior warning. However, a positive aspect is reflected in the development of several remote mental health care devices implemented to protect vulnerable population, frontline workers, and the general population. Finally, this paper underscores the importance of developing public policies for protecting workers' mental health.

ABSTRACT

Abstract Objectives The present study aimed to evaluate the measurement invariance of a general measure of the perception of governmental responses to COVID--19 (COVID-SCORE-10) in the general population of 13 Latin American countries. Methods A total of 5780 individuals from 13 Latin American and Caribbean countries selected by non-probabilistic snowball sampling participated. A confirmatory factor analysis was performed and the alignment method was used to evaluate invariance. Additionally, a graded response model was used for the assessment of item characteristics. Results The results indicate that there is approximate measurement invariance of the COVID-SCORE-10 among the participating countries. Furthermore, IRT results suggest that the COVID-SCORE-10 measures with good psychometric ability a broad spectrum of the construct assessed, especially around average levels. Comparison of COVID-SCORE-10 scores indicated that participants from Cuba, Uruguay and El Salvador had the most positive perceptions of government actions to address the pandemic. Thus, the underlying construct of perception of government actions was equivalent in all countries. Conclusion The results show the importance of initially establishing the fundamental measurement properties and MI before inferring the cross-cultural universality of the construct to be measured.

ABSTRACT

Abstract The aim of the present study was to translate into Spanish and evaluate the psychometric evidence of the Impact on Quality of Life (COV19-QoL) applied to a sample of Peruvian older adults ( N = 298; 58.1% women, 41.9% men, mean age 65.34 years [SD = 11.33]). The study used techniques from the Classical Test Theory (CTT) and Item Response Theory (IRT). The findings confirmed the single factor structure of the COV19-QoL, high internal consistency reliability, measurement invariance by gender, and all items demonstrated adequate discrimination and difficulty indices. In this sense, the items allow adequate discrimination between low, medium and high levels of the impact of the COVID-19 pandemic on quality of life. In addition, a greater perceived impact of the pandemic on quality of life is necessary to answer the higher response options of the COV19-QoL. In conclusion, the COV19-QoL is a valid measurement scale of the impact of the COVID-19 pandemic on the quality of life of Peruvian older adults.

ABSTRACT

Abstract Thousands of people have died of COVID-19 in El Salvador. However, little is known about the mental health of those who are mourning the loss of a loved one to COVID-19. Therefore, the objective of this study was to examine the dysfunctional grief associated with COVID-19 death among Salvadoran adults. A sample of 435 Salvadorans ( M = 29 years; SD = 8.75) who lost a family member or loved one to COVID-19 completed a digital survey using the Google Forms platform, during April 2 and 28, 2022. The results revealed that 35.1% reported clinically elevated symptoms of dysfunctional grief and among those mourners, and 25.1% also exhibited clinical levels of coronavirus anxiety. A binary logistic regression revealed that predictor variables such as COVID-19 anxiety ( p = .003), depression ( p = .021), and COVID-19 obsession ( p = .032) were significant ( χ 2 = 84.31; Nagelkerke R 2 = .242) and predict a 24.2% chance of dysfunctional bereavement.

ABSTRACT

ABSTRACT Verbal fluency tasks are frequently used in neuropsychological assessment, standing out for their easy application and good sensitivity to early cognitive impairment. However, in Argentina, the availability of updated norms is limited, especially for the action fluency variant. There is also little evidence of validity. Objectives: The aim of this study was to obtain Argentine norms for three verbal fluency tasks and to analyze their convergent validity. Methods: Using a nonprobability sampling method, 303 Argentines from a nonclinical population (age mean=66.8, 50-91 years) were recruited to participate in this study. Those with medical conditions that could compromise neuropsychological performance were excluded. Three verbal fluency tasks (i.e., phonological, semantic, and action), the Montreal Cognitive Assessment (MoCA) test, and the Digit Span-WAIS III test were administered. Correlations and multiple regressions were subsequently performed. Results: Education and age significantly explained 11.8% of the variance in phonological fluency, 15.8% of the variance in semantic fluency, and 20.2% of the variance in action fluency. Hence, the normative data varied according to educational level and age group, with normal performance limit values between 9 and 14 for phonological fluency, 11 and 18 for semantic fluency, and 8 and 17 for action fluency. Positive correlations were obtained between all verbal fluency tasks, as well as between the MoCA test and the Digit Span test. Conclusions: This study supports the applicability of three verbal fluency tasks in an Argentine context by providing age- and education-corrected norms and acceptable evidence of convergent validity.


RESUMO As tarefas de fluência verbal são frequentemente utilizadas na avaliação neuropsicológica, destacando-se pela facilidade de aplicação e boa sensibilidade ao comprometimento cognitivo incipiente. No entanto, na Argentina, a disponibilidade de padrões atualizados é limitada, especialmente pela variante de fluência de ações. Assim sendo, a evidência de validade é escassa. Objetivos: Obter normas argentinas para três tarefas de fluência verbal e analisar sua validade convergente. Métodos: Usando um método de amostragem não probabilística, 303 argentinos de uma população não clínica (idade M=66,8, 50-91 anos) foram recrutados para participar deste estudo. Foram excluídos aqueles com condições médicas que pudessem comprometer o desempenho neuropsicológico. Três tarefas de fluência verbal (ou seja, fonológica, semântica e ações), o teste Montreal Cognitive Assessment (MoCA) e o teste Digit Span-WAIS III foram administrados. Correlações e regressão múltipla foram realizadas posteriormente. Resultados: A escolaridade e a idade explicaram significativamente 11,8% da variância da fluência fonológica, 15,8% da variância da fluência semântica e 20,2% da variância da fluência de ações. Assim, os dados normativos variaram de acordo com a escolaridade e a faixa etária, com limite de desempenho normal entre 9 e 14 para fluência fonológica, 11 e 18 para fluência semântica e 8 e 17 para fluência de ações. Foram obtidas correlações positivas entre todas as tarefas de fluência verbal, bem como entre estas, o teste MoCA e o Digit Span. Conclusões: Este estudo apoia a aplicabilidade de três tarefas de fluência verbal no contexto argentino, fornecendo normas corrigidas por idade e educação e evidências aceitáveis de validade convergente.

ABSTRACT

ABSTRACT The Mini-Mental State Examination (MMSE) was created by Marshal Folstein et al. in 1975 as an instrument for brief (5-10 min) assessment of mental status in hospitalized patients. It is considered the most widely used test for standardized cognitive assessment in the clinical setting, especially with the elderly population. It has countless translations in different languages, and according to the different international (PubMed) and regional (SciELO, Redalyc, and Dialnet) scientific databases, it has been widely used by the scientific community. This article describes the historical evolution of the MMSE, highlights its evaluative properties, and provides bibliometric data on its impact on scientific publications, with a special focus on Ibero-America.


RESUMO El Mini-mental State Examination (MMSE) fue creado por Marshal Folstein et al. en 1975 como un instrumento para la evaluación breve (5-10 minutos) del estado mental de pacientes hospitalizados. Se lo considera la prueba más utilizada para la evaluación cognitiva estandarizada en el ámbito clínico, especialmente con la población adulta mayor. Tiene innumerables traducciones a diferentes idiomas y de acuerdo con las diferentes bases de datos científicas internacionales (PudMed) y regionales (Scielo, Redalyc y Dialnet) se puede constatar que ha sido ampliamente utilizada por la comunidad científica. En este trabajo se describe la evolución histórica del MMSE, se destacan sus propiedades evaluativas y se indican datos bibliométricos acerca de su impacto en las publicaciones científicas, con especial énfasis en IberoAmérica.

ABSTRACT

In this paper, we offer an in-depth analysis of relevant scientific literature and a series of critical reflections based on a narrative review of the impact that the early stages of the Covid-19 pandemic had on Latin American psychology. We performed a non-exhaustive search, selection, and analysis of different documentary sources in scientific databases, institutional repositories, and websites of national and regional psychology organizations between May 25 and 31, 2020. In particular, we consulted SciELO, Redalyc, Dialnet, and Google Scholar using the following individual key words associated to psychology: "Coronavirus", "Covid-19" and "Pandemic". Various types of documents were retrieved for a subsequent in-depth analysis (e.g., articles, institutional documents, notes, bulletins, recommendation guides, etc.). Our review allowed us to identify three challenges for psychology in the region: (1) insertion of psychology in public policies; (2) construction of an own agenda of psychological research; (3) evaluation of practices and reorientation of professional training processes.


Neste artigo, é oferecida uma análise aprofundada da literatura científica relevante e uma série de reflexões críticas baseadas em uma revisão narrativa do impacto que os estágios iniciais da pandemia de Covid-19 tiveram na psicologia latino-americana. Foi realizada uma busca não exaustiva, seleção e análise de diferentes fontes documentais em bancos de dados científicos, repositórios institucionais e websites de organizações nacionais e regionais de psicologia entre 25 e 31 de maio de 2020. Em particular, foram consultadas as bases SciELO, Redalyc, Dialnet e Google Scholar usando as seguintes palavras-chave individuais associadas à psicologia: "coronavírus", "Covid-19" e "pandemia". Vários tipos de documentos foram recuperados para uma análise posterior em profundidade (por exemplo: artigos, documentos institucionais, notas, boletins, guias de recomendação, etc.). A revisão feita pelos autores permitiu identificar três desafios para a psicologia na região: (1) inserção da psicologia nas políticas públicas; (2) construção de uma agenda própria de pesquisa psicológica e (3) avaliação das práticas e reorientação dos processos de formação profissional.

ABSTRACT

Este artículo analiza el estado de salud mental de población adulta de México en el contexto de pandemia ocasionada por el virus SARS-CoV-2 (COVID-19). Participaron 899 participantes de diferentes regiones de México Medad = 34. 8, DE= 11.38, mujeres= 641, hombres=258, durante el contexto de pandemia por COVID-19. Los instrumentos aplicados fueron la Escala de Miedo al COVID-19 (FCV-19S), la Escala para el Trastorno de Ansiedad Generalizada (GAD-7), el Test de Propósito de Vida (PIL), el Cuestionario de Salud del Paciente (PHQ-9) y el Cuestionario Medical Outcomes Study (MOS) para el apoyo social. La aplicación se realizó de manera individual, durante el período del 12 de junio al 14 de septiembre de 2020. Los resultados indicaron que los participantes no presentaron síntomas agudos de miedo hacia la COVID-19. No obstante, se encontró presencia considerable de ansiedad generalizada y de depresión en diferentes niveles. El apoyo social y propósito de vida se encuentran presentes, contrarrestando la ansiedad y la depresión, mientras que el miedo y la cantidad de horas de exposición a pensamientos sobre COVID-19 contribuyeron de forma positiva a estas variables psicológicas. Se concluye que la crisis sanitaria ocasionada por COVID-19 ha impactado fuertemente en la salud mental de los participantes, no obstante, existen fortalezas como el apoyo social y el propósito de vida que ayudan a sobrellevar los efectos de la pandemia y se debería trabajar en ellas para promover la salud mental durante los momentos de la crisis sanitaria(AU)


This paper analyzes the status of mental health of the adult population of Mexico in the context of the pandemic caused by the SARS-CoV-2 virus (COVID-19). This article analyzes the mental health status of the adult population of Mexico in the context of the pandemic caused by the SARS-CoV-2 virus (COVID-19). A total of 899 participants from different regions of Mexico participated, M age = 34.8, SD= 11.38, women= 641, men=258, during the context of the COVID-19 pandemic. The instruments applied were the COVID-19 Fear Scale (FCV-19S), the Generalized Anxiety Disorder Scale (GAD-7), the Purpose I Life Test (PIL), the Patient Health Questionnaire (PHQ -9) and the Medical Outcomes Study (MOS) Questionnaire for social support. The application was carried out individually, during the period from June 12 to September 14, 2020. The results indicated that the participants did not present acute symptoms of fear towards COVID-19. However, a considerable presence of generalized anxiety and depression was found at different levels. Social support and life purpose are present, counteracting anxiety and depression, while fear and the number of hours of exposure to thoughts about COVID-19 contributed positively to these psychological variables. It is concluded that the health crisis caused by COVID-19 has strongly impacted on the mental health of the participants; however, there are strengths such as social support and life purpose that help to cope with the effects of the pandemic. Therefore, these two strengths should be worked on to promote mental health during times of health crisis(AU)

ABSTRACT

El objetivo de este trabajo consiste en describir el grado de aceptación o no a ciertas creencias de conspiración sobre las vacunas contra la COVID-19 en una muestra de países miembros de la Comunidad Andina de Naciones (CAN): Bolivia, Colombia, Ecuador y Perú. Se diseñó un estudio transversal descriptivo en el que participaron 1835 personas de Bolivia, Colombia, Ecuador y Perú. Para la evaluación de estas creencias se utilizó la Escala de Creencias de Conspiración de Vacunas COVID-19 (ECCV-COVID, Caycho-Rodríguez et al., 2022a). Los resultados indican que, el Perú presenta el mayor puntaje promedio de creencias de conspiración sobre las vacunas contra la COVID-19. Además, en los 4 países el menor grado de aceptación es con la creencia sobre "Vacunar a los niños contra la COVID-19 es perjudicial y este hecho está ocultado". En Colombia, Ecuador y Perú el mayor grado de aceptación está referida a la creencia conspirativa referida a que "La información sobre la seguridad de las vacunas contra la COVID-19 a menudo se inventan". Finalmente, en Bolivia, el mayor grado de aceptación es con la creencia de que "Las empresas farmacéuticas ocultan los peligros de las vacunas contra la COVID-19". Los resultados presentados en este estudio son los primeros que se conoce de forma genérica en población latinoamericana, y particularmente, en la población Andina(AU)


Studies on the acceptance and rejection of vaccines, as well as the belief in conspiracy theories, and the lack of trust in governments and science, have been important to analyze the vaccination process against COVID-19 worldwide, but they have been quite limited, so far, in the case of Latin America. In this sense, the objective of this work is to describe the degree of acceptance or not of certain conspiracy beliefs about vaccines against COVID-19 in a sample of countries members in the Andean Community of Nations (CAN): Bolivia, Colombia, Ecuador and Peru. A descriptive cross-sectional study was designed in which 1835 people from Bolivia, Colombia, Ecuador and Peru participated. To evaluate these beliefs, the COVID-19 Vaccine Conspiracy Belief Scale (ECCV-COVID, Caycho-Rodríguez et al., 2022a) was used. The results indicate that Peru has the highest average score of conspiracy beliefs about vaccines against COVID-19. In addition, in the 4 countries, the lowest degree of acceptance is with the belief that "Vaccinating children against COVID-19 is harmful and this fact is hidden". In Colombia, Ecuador and Peru, the highest degree of acceptance is related to the conspiratorial belief that "Information on the safety of vaccines against COVID-19 is often invented." Finally, in Bolivia, the highest degree of acceptance is with the belief that "Pharmaceutical companies hide the dangers of vaccines against COVID-19". The results presented in this study are the first known generically in the Latin American population, and particularly in the Andean population(AU)

ABSTRACT

The COVID-19 pandemic has not only had health, economic, and political impacts, but also significant psychosocial and mental health consequences worldwide. In this article, different documentation and studies on mental health were analyzed, with the aim of identifying the various problems detected during the pandemic. Methodologically, a narrative and integrative review of the scientific literature was carried out. In Latin America, the most recent studies have documented and made patent effects on the various vulnerized populations such as migrants, women, children, the elderly, people living with significant disabilities, people experiencing marked housing and food insecurity, and temporary workers laboring in what has been referred to as the informal economy. In light of this, it is proposed that addressing these issues should involve the coordination of transnational policies and the definition of an agenda of critical priorities to focus and address. For this to come about, it is important that the empirical evidence generated by regional epidemiological studies contribute to the design of public policies on mental health of the Latin American population, so that they reduce the negative effects as well as prevent the future consequences of a pandemic that is not yet over.(AU)


A pandemia da COVID-19 no mundo tem impactado a área da saúde, os setores da economia e da política e também tem gerado consequências psicossociais, repercutindo de forma significativa no campo da saúde mental. Este estudo de revisão sistemática analisou diversos documentos e pesquisas abordando saúde mental e COVID-19, bem como problematicas geradas durante a pandemia. A metodologia de pesquisa envolveu revisão narrativa e integrativa da literatura científica. Na América Latina, os estudos mais recentes apresentam os inúmeros efeitos da COVID-19 em populações vulneráveis: imigrantes, mulheres, crianças, idosos, pessoas em situação de rua, trabalhadores informais, etc. Diante desse panorama, propõe-se que a abordagem dessas questões inclua a coordenação de políticas transnacionais e a definição de uma agenda de prioridades críticas a serem consideradas. Os resultados empíricos de estudos epidemiológicos realizados em âmbito regional contribuíram para o desenho de políticas públicas em saúde mental da população latino-americana com o objetivo de reduzir os efeitos negativos e prevenir riscos futuros de uma pandemia que ainda não terminou.(AU)


La pandemia por el COVID-19 no sólo ha generado diversos impactos en materia de salud, economía y política, sino también importantes consecuencias psicosociales y de salud mental en el mundo. En este trabajo, se analizaron diferentes documentaciones y estudios sobre salud mental, con el objetivo de recuperar las diversas problemáticas detectadas durante la pandemia. Metodológicamente se realizó una revisión narrativa e integrativa de la literatura científica. En América Latina los estudios más recientes comienzan a visualizar diferentes afectaciones sobre las diversas poblaciones vulneralizadas: migrantes, mujeres, niños, los ancianos, personas quienes viven con una discapacidad significativa, personas en situación de calle, trabajadores informales, etc. Frente a este panorama, se plantea que el abordaje de estas cuestiones deberá contar con la coordinación de políticas trasnacionales y la definición de una agenda de prioridades críticas a focalizar y atender. Para esto resulta importante que la evidencia empírica generada por los estudios epidemiológicos regionales contribuya al diseño de las políticas públicas sobre salud mental de la población latinoamericana, de modo que las mismas logren reducir los efectos negativos como también puedan prevenir las consecuencias futuras de una pandemia que todavía no ha finalizado.(AU)

ABSTRACT

Resumen En este estudio evaluamos las microalgas Chlorella vulgaris y Demodesmus asymmetricus, con el fin de determinar la proporción de microalgas que remueven la mayor concentración de nitrógeno y fósforo en aguas residuales de una planta de tratamiento. Se realizó un diseño de mezclas de las microalgas con el agua residual durante 9 días, con fotoperiodo 12:12 h, en un invernadero. Las mayores eficiencias de remoción de nitrógeno (principalmente NO3 -N y NO2 -N) y fósforo (PO4 ) se observaron en los tratamientos con mayor proporción de D. asymmetricus, entre ellos sobresalió el tratamiento T3 (25% C. vulgaris / 75% D. asymmetricus) donde se removió el 100% de nitrógeno y 77.1% de fósforo. De igual manera con el oxígeno disuelto (OD), el T3 obtuvo el mejor resultado alcanzando una media de 25.50 ± 0.28 mg/L. Finalmente, de acuerdo con el análisis del diseño de mezclas, se determinó que la mezcla óptima de microalgas que logra la mayor producción de OD y la mayor remoción, fue la proporción de 6% de C. vulgaris y 94% de D. asymmetricus en un tiempo de cultivo de 9 días. En conclusión, las microalgas demuestran su capacidad de biorremediación de aguas residuales domésticas.


Abstract In this work, we evaluated the proportion Chlorella vulgaris and Demodesmus asymmetricus microalgae, that removes the highest concentration of nitrogen and phosphorus in wastewater from a treatment plant. A mixture design was employed in this study, for 9 days, with 12:12 h photoperiod, in a greenhouse. The highest nitrogen removal efficiencies (mainly NO3 -N and NO2 -N) and phosphorus (PO4 ) were observed in treatments with the highest proportion of D. asymmetricus, including T3 (25% C. vulgaris / 75 % D. asymmetricus), where 100.0% nitrogen and 77.1% phosphorus were removed. Likewise, T3 obtained the best result of dissolved oxygen (DO), achieving average of 25.50 ± 0.28 mg/L. Finally, according to the analysis of the mixture design, the optimal microalgae mixture was determinated that achieves the highest DO production, and the highest removal was the proportion of 6% of C. vulgaris and 94% of D. asymmetricus in 9 days cultivation time. In conclusion, microalgae have shown their capacity for bioremediation of domestic wastewater, which is an alternative to consider.

ABSTRACT

Resumen La bibliometría consiste en el tratamiento matemático y estadístico de la información científica y, por ello, se la concibe como la cuantificación de la información bibliográfica susceptible de ser analizada. Más allá de que algunos autores la conciban como una metodología y otros como una técnica, la bibliometría facilita la organización, selección y categorización de la información para un tratamiento cuantitativo y cualitativo. Desde hace más de tres décadas, los estudios bibliométricos han comenzado a proliferar con diferentes usos, orientaciones y aplicaciones en el campo de la psicología iberoamericana. En este trabajo se analizan los estudios bibliométricos en el campo de la psicología iberoamericana recuperados de tres bases de datos: Dialnet (España), Redalyc (México) y SciELO (Brasil). A partir de una muestra de 81 trabajos seleccionados, se realizó una categorización según las diferentes líneas de investigación, los autores más frecuentes, los países de los autores, el rango de años de las publicaciones, el idioma de las publicaciones, el género en la redacción de los trabajos, las revistas que más estudios bibliométricos publicaron y las más analizadas desde la perspectiva bibliométrica. También se analizó el contexto histórico de aparición de los estudios bibliométricos en el campo de la psicología de Iberoamérica. Se concluye que los estudios bibliométricos son un importante recurso metodológico para la evaluación de la disciplina y profesión psicológica, siempre que logren ir más allá de la mera descripción de datos cuantitativos y puedan complementarse con análisis cualitativos, lo que brindaría mayor potencialidad interpretativa y explicativa.


Abstract Bibliometry consists on the mathematical and statistical treatment of published scientific information. This methodology, or technique (following some authors), includes the quantification of bibliographic information that can be analyzed. Bibliometric and qualitative data reviews can be combined in order to offer high-quality conclusions. For more than three decades, bibliometric studies have proliferated with different uses, orientations, and applications in Ibero-American psychology. All the classic areas of psychology (basic psychological processes, clinical and health psychology, organizational and work psychology, educational psychology), as well as new areas, such as sports psychology, traffic psychology, consumer psychology, and others have been subject of bibliometric works. Several productions can be recognized where bibliometry is used for historical analysis, review of specialized literature, scientific journals analysis, and the recognition of different areas of research. The goal of this work is to provide a metabibliometric analysis, that is, a bibliometry of bibliometric studies. It is a descriptive study in which different documentary sources are retrieved, classified, and analyzed based on the proper procedure of bibliometric studies. This study examined the scientific and scholarly productions in the field of Ibero-American psychology, using three specific databases: Dialnet (Spain), Redalyc (Mexico), and SciELO (Brazil). The choice of such databases was because they provide the indexation of a large number of psychology journals and also allow free access to their contents, which gives some coverage to the psychological production of the Ibero-American region. The search was guided by the following general descriptors: "Bibliometric" and "Psychology", present in any of the search fields of these databases. These two words are functionally equivalent to detect items in Spanish and Portuguese (because all articles have abstracts in English). Interdisciplinary studies were ruled out, and those clearly outside of psychological science or the profession of psychology. The final refined sample of 81 articles were classified according to the following indicators: a) lines of research; b) more frequent authors; c) countries of the authors; d) range of years of publications; e) language of the publications; f) gender in the writing of the works; g) the journals that published the most bibliometric studies; and h) the most analyzed journals from the bibliometric perspective. The vast majority of articles are from the present century (70), which highlights the recent explosion of work in the field. For reference only, eight articles were published in the 1990s, 34 articles were published in the 2000s, and 36 articles were published in the current half-decade. The language of the articles is distributed as follows: 71 in Spanish (88 %), 5 in English (6 %), and 5 in Portuguese (6 %). The proportion by gender of correspondence authors reflects that 40 % are women (33 articles), and 60 % are men (48 articles), always considering the first signatory in cases of multiple authorship. The countries according to the correspondence author, taking the first author in the cases of multiple authorships, are: Spain (45), Colombia (15), Argentina (6), Brazil (5), Mexico (4), Chile (3), Peru (2) and Costa Rica (1). Results confirm that the bibliometric research design is a consistent methodological approach to evaluate the field of psychology as a discipline and a professional practice in Ibero-America. These results do not reflect the entire set of bibliometric research in Ibero-American psychology. However, they can also be considered as a representative map of bibliometric studies in the region. The most significant criticism that can be indicated for these bibliometric studies is the abusive descriptive perspective that appears in them. It would be desirable for this kind of research to incorporate other analytical perspectives to go beyond the purely descriptive, which could obtain greater interpretative and explanatory potential regarding what was investigated.
