ABSTRACT Background: The Positive Organizational Culture construct is a set of shared practices, values, and behaviors within an organization that promote healthy and motivating working environments. This study develops a new scale called the Positive Organizational Culture Scale (POCS) to assess how organizational values affect well-being and work performance. Method: The sample consisted of 1,420 workers in Chile, with an average age of 39.48 years (SD = 11.13). Over half (55.0%) worked in the public sector, 34.5% worked in private organizations, and 10.5% worked in private non-profit organizations. The study examined item descriptions, the scale’s internal structure, its measurement invariance regarding sex and organization, and its relationship with other psychological variables (organizational climate, professional burnout, psychosomatic symptomatology). Results: The POCS showed a good fit to a correlated two-factor structure (People-Oriented Culture and Results-Oriented Culture; CFI = .94; RMSEA = 0.08), demonstrating measurement invariance regarding sex and type of organization. The findings show that the POCS has 36 items exhibiting satisfactory psychometric properties and a structure consisting of two first-order factors, which exhibit distinct associations with the other recorded variables. Conclusions: The POCS provides relevant information for formulating actions aimed at enhancing the work environment in the Chilean context.

Magnetic-activated cell sorting (MACS) can be used to separate apoptotic sperm with high proportions of fragmented DNA from the rest, thus improving the overall quality of the seminal sample. Therefore, the aim of this retrospective study was to investigate the efficiency of the MACS technique to increase reproductive outcomes in patients with high levels of sperm DNA fragmentation (SDF) undergoing intracytoplasmic sperm-injection (ICSI) cycles. In this study, we analyzed a total of 724 assisted-reproduction-technique (ART) cycles that were divided into two groups: the study group (n = 366) in which the MACS selection technique was performed after density-gradient centrifugation (DGC), and the control group (n = 358) in which only DGC was used for sperm selection. Reproductive outcomes were analyzed in both groups according to three different ART procedures: preimplantation genetic testing for aneuploidy (PGT-A), and autologous and oocyte-donation cycles. The MACS group showed significantly lower miscarriage rates in autologous ICSI cycles, higher pregnancy rates in oocyte-donation cycles, and a significant increase in live-birth rates in both autologous and oocyte-donation cycles. Overall, these results suggested that the MACS technique can be effectively used to eliminate sperm with high SDF levels, and therefore may help to improve reproductive outcomes in couples undergoing ART.

Likert items are often used in social and health sciences. However, the format is strongly affected by acquiescence and reversed items have traditionally been used to control this response bias, a controversial practice. This paper aims to examine how reversed items affect the psychometric properties of a scale. Different versions of the Grit-s scale were applied to an adult sample (N = 1,419). The versions of the scale had either all items in positive or negative forms, or a mix of positive and negative items. The psychometric properties of the different versions (item analysis, dimensionality and reliability) were analyzed. Both negative and positive versions demonstrated better functioning than mixed versions. However, the mean total scores did not vary, which is an example of how similar means could mask other significant differences. Therefore, we advise against using mixed scales, and consider the use of positive or negative versions preferable.

Acceptance and Commitment Therapy states that Experiential Avoidance contributes to the development of psychological issues. The Acceptance and Action Questionnaire-II measures Experiential Avoidance. The objective of the current study is to perform a validation of the Acceptance and Action Questionnaire-II in the general Spanish population. A sample of 964 participants from all over Spain was used ( M  = 43.43 years; SD  = 15.27). The psychometric properties of the questionnaire were examined according to Classical Test Theory. In addition, assessments were made of participants’ personality, Emotional Intelligence, Anxiety, and Depression, and the influence of sex and age on Experiential Avoidance was examined. The Acceptance and Action Questionnaire-II is a unidimensional instrument, with excellent reliability (α = .93) and adequate evidence of validity. Differences were observed based on sex, with women scoring higher, and based on age, with lower scores in the older age groups. The Acceptance and Action Questionnaire-II is a valid, reliable instrument for use in the general Spanish population.

Background: Previous research about use of Social Networking Sites (SNS) use during the COVID-19 lockdown has examined benefits and risks of SNS use (i.e., support through SNS, problematic SNS use and interaction about COVID-19) without comparing them. This study has two objectives: (i) to evaluate which SNS uses (problematic SNS use and interaction about COVID-19 on SNS) predict increased emotional distress, and (ii) to analyse if social support and interaction about COVID-19 mediated the relationship between time spent on SNS and increased emotional distress. Method: A total of 1,003 participants (75.5% women) over 18 years old took part (M = 42.33; SD = 14.32 years). Three hierarchical linear regressions were performed for the first objective and a path analysis was performed for the second. Results: Results showed that negative social comparison on SNS had the highest positive regression weight, followed by interaction about COVID-19 and addictive consequences. Also, an indirect effect of time spent on SNS on anxiety, depression, and life satisfaction through interaction about COVID-19 and support through SNS was found. Conclusions: The results indicate that comparative SNS use is the best predictor of emotional distress. The mediation model proposed was confirmed, highlighting the importance of assessing specific SNS uses.

The research on Masculinity and Femininity has a long history. Despite this, there is still discussion about the nature of these concepts. In the present study, the development of the Oviedo Gender Roles Scale (GRSO) is presented. A sample of 612 participants belonging to general Spanish population is used (Myears = 34.2; SDyears = 15.9). The dimensionality, discrimination indices, reliability and evidence of convergent and divergent validity of the instrument were studied. In addition, differences in general (Big Five model) and specific personality traits based on sex were measured and an ANCOVA was performed controlling the variables of Masculinity and Femininity. A good fit to a threefactor multidimensional structure, with Cronbach’s alphas indicating good reliability (Socioemotional = .75; Comparison = .81; Aggressiveness = .77) and adequate evidence of validity were observed. Differences based on sex were observed in various personality traits, but when controlling for Masculinity and Femininity, such differences disappeared. ERGO is a reliable and valid test for the study of gender roles. The implication of a multidimensional approach on Masculinity and Femininity is discussed.

El objetivo del estudio fue desarrollar la Escala de Cultura Organizacional Positiva (ECOP), la cual evalua como los valores organizacionales afectan el bienestar y rendimiento laboral. Metodo: La muestra fueron 1.420 trabajadores de Chile, con una edad media de 39,48 afios (DT = 11,13). El 55% eran trabajadores del sector publico, el 34,5% de organizaciones privadas y el 10,5% de organizaciones privadas sin fines de lucro. Se estudiaron los descriptivos de los items, la estructura interna de la escala, su invarianza de medida en terminos de sexo y organizacion y su relacion con otras variables psicologicas (clima organizacional, desgaste profesional, sintomatologia psicosomatica). Resultados: La ECOP mostro un buen ajuste a una estructura de dos factores correlacionados (Cultura Orientada a las Personas y Cultura Orientada a los Resultados; CFI = .94; RMSEA = 0.08), demostrando invarianza de medida en terminos de sexo y tipo de organizacion. Los factores mantienen relaciones diferentes con las otras variables registradas. Conclusiones: La ECOP ofrece informacion relevante para el desarrollo de intervenciones que fortalezcan el ambiente laboral en el contexto chileno.

Este estudio tiene dos objetivos: a) evaluar qué uso de RRSS predice mejor el incremento de distrés emocional, y b) analizar si el apoyo y la interacción sobre COVID-19 en RRSS media la relación entre el tiempo de uso y el distrés emocional. Método: La muestra constó de 1,003 participantes (75.5% mujeres) mayores de 18 años (M = 42.33; DT = 14.32). Se llevaron a cabo tres regresiones lineales jerárquicas para el primer objetivo y un path análisis para el segundo. Resultados: La comparación social negativa en RRSS tiene el mayor peso de regresión, seguido de interacción sobre el COVID-19 y consecuencias adictivas. Se ha obtenido un efecto indirecto del tiempo de uso sobre el distrés emocional a través de la interacción sobre COVID-19 y el apoyo mediante RRSS. Conclusiones: Los resultados indican que el uso comparativo de RRSS es el mejor predictor de distrés emocional. Se ha confirmado el modelo de mediación, enfatizando la importancia de la evaluación de usos específicos de RRSS. Palabras clave: Redes Sociales Ansiedad Depresión COVID-19 Apoyo social

Endometriosis, despite only affecting 10-15% of women of fertile age, is still an enigmatic disease. Recent developments in assisted reproductive technology have contributed to a better understanding of where and how endometriosis could compromise fertility. In this mini-review we will show how the main point of damage in endometriosis is quantitative impairment of the ovaries, if the \"less is more\" mantra should be applied when considering ovarian surgery, and when fertility preservation prior to ovarian surgery could be considered. Endometrial receptivity, however, does not seem to be affected.

La investigación de la Masculinidad y la Feminidad posee una larga trayectoria. A pesar de ello, aún se continúa discutiendo sobre la naturaleza de estos conceptos. En el presente estudio, se presenta el desarrollo de la Escala de Roles de Género de Oviedo (ERGO). Se empleó una muestra de 612 participantes procedentes de la población general española (Maños = 34.2; DTaños = 15.9). Se estudió la dimensionalidad, los índices de discriminación, la fiabilidad y las evidencias de validez divergente y convergente del instrumento. Además, se estudiaron diferencias en rasgos generales (modelo Big Five) y específicos de personalidad en función del sexo, y se realizó un ANCOVA controlando las variables de Masculinidad y Feminidad. Se observó un buen ajuste a una estructura multidimensional de tres factores, con alfas de Cronbach indicando una fiabilidad buena (Socioemocional = .75; Comparación = .81; Agresividad = .77) y adecuadas evidencias de validez. Se observaron diferencias en función del sexo en varios rasgos de personalidad, pero, al controlar la Masculinidad y Feminidad, las diferencias desaparecieron. El ERGO es una prueba válida y fiable para el estudio de los roles de género. Se discute la implicación de una aproximación multidimensional de la Masculinidad y Feminidad.
