Calidad de vida en adolescentes. Un estudio longitudinal del impacto de la pandemia por COVID-19 / Quality of life in adolescents. A longitudinal study of the impact of the COVID-19 pandemic

Diversos estudios han informado que la calidad de vida relacionada con la salud (CVRS) en adolescentes ha disminuido durante la pandemia por COVID-19. En este trabajo se analizó la CVRS en jóvenes de 13 a 17 años una vez finalizada la pandemia. Para ello se hizo un seguimiento en tres momentos diferentes: antes de la pandemia (2019), durante las restricciones de la pandemia (2021) y tras las restricciones de la misma (2022). Se utilizó un diseño de retardo temporal (time-lag design) en tres fases, con un total de 2027 adolescentes que cumplimentaron el cuestionario Kidscreen-10 de CVRS. Mediante modelos ANOVA y de regresión logística se analizó la influencia del género, la práctica deportiva y estar en tratamiento en salud mental. Los resultados obtenidos mostraron un empeoramiento de la CVRS en 2021, cuando los jóvenes volvían a los centros educativos en régimen de semipresencialidad. Este descenso fue independiente del género. En 2022, una vez eliminadas todas las restricciones, la CVRS se recuperó a niveles prepandemia en los chicos, pero no en las chicas. Lo mismo ocurrió con los jóvenes en tratamiento de salud mental. En todos los casos, la práctica deportiva se mostró como un factor protector de la CVRS.(AU)

Several studies have reported that health-related quality of life (HRQoL) in adolescents has decreased during the COVID-19 pandemic. In this study, HRQoL was analyzed in young people aged 13 to 17 years after the end of the pandemic. For this purpose, we followed up at three different points in time: before the pandemic (2019), during (2021) and af-ter the pandemic restrictions (2022).A time-lag design in three phases was used, with a total of 2027 adolescents completing the Kidscreen-10 HRQoL questionnaire. ANOVA and logistic regression models were used to analyze the influence of gender, playing sports and mental health treat-ment.The results obtained showed a worsening of HRQoL in 2021, when young people returned to school on a blended learning basis.This worsen-ing occurred regardless of gender. In 2022, once all restrictions were re-moved, boys recovered health-related quality of life to pre-pandemic levels, but this did not occur in girls. The same happened with young people in mental health treatment. In all cases, doing sports was shown to be a pro-tective factor for HRQoL.(AU)

Strengths and Difficulties Questionnaire (SDQ): An update of the literature and instrumental study with schoolchildren

Introduction: Considering the current controversy regarding the factorial structure of the SDQ, this paper aimed to analyse the dimensionality and reliability of the parents' version for children from 4 to 16 years of age, and to present descriptive data according to sociodemographic variables. Method: The factor structure of the original five- and three-factor models, and the reliability of the SDQ were examined among a sample of 621 parents of Uruguayan children between 7 and 12 years of age (52% girls) from different socioeconomic levels. Results: Confirmatory factor analyses did not provide support for the five- and three-factor models. Data adjusted to three factors (prosociality, externalising symptoms, internalising symptoms) in an exploratory analysis with adequate reliability indices. Conclusions: The results of this study show the relevance of continued investigation of the SDQ internal structure, and further analysis of the behaviour of several of its items.

Introducción: Considerando la controversia vigente respecto a la estructura factorial del SDQ, este trabajo tuvo como objetivo analizar la validez de constructo y fiabilidad de la versión para padres de niños de 4 a 16 años y presentar datos descriptivos según variables sociodemográficas. Método: Se examinó la estructura factorial de los modelos originales de cinco y tres factores y la fiabilidad del SDQ en una muestra de 621 padres de niños uruguayos entre 7 y 12 años (52 % niñas) de distintos niveles socioeconómicos. Resultados: Los análisis factoriales confirmatorios no pudieron dar apoyo a los modelos de cinco y tres factores. Los datos se ajustaron a tres factores (prosocialidad, síntomas externalizantes y síntomas internalizantes) en un análisis exploratorio con adecuados índices de fiabilidad. Conclusiones: Los resultados de este estudio muestran la pertinencia de continuar investigando la estructura interna del SDQ y analizar con mayor profundidad el comportamiento de algunos de sus ítems.

Integrated multidisciplinary ecological analysis from the Uluzzian settlement at the Uluzzo C Rock Shelter, south-eastern Italy.

The Middle to Upper Palaeolithic transition, between 50 000 and 40 000 years ago, is a period of important ecological and cultural changes. In this framework, the Rock Shelter of Uluzzo C (Apulia, southern Italy) represents an important site due to Late Mousterian and Uluzzian evidence preserved in its stratigraphic sequence. Here, we present the results of a multidisciplinary analysis performed on the materials collected between 2016 and 2018 from the Uluzzian stratigraphic units (SUs) 3, 15 and 17. The analysis involved lithic technology, use-wear, zooarchaeology, ancient DNA of sediments and palaeoproteomics, completed by quartz single-grain optically stimulated luminescence dating of the cave sediments. The lithic assemblage is characterized by a volumetric production and a debitage with no or little management of the convexities (by using the bipolar technique), with the objective to produce bladelets and flakelets. The zooarchaeological study found evidence of butchery activity and of the possible exploitation of marine resources, while drawing a picture of a patchy landscape, composed of open forests and dry open environments surrounding the shelter. Ancient mitochondrial DNA from two mammalian taxa were recovered from the sediments. Preliminary zooarchaeology by mass spectrometry results are consistent with ancient DNA and zooarchaeological taxonomic information, while further palaeoproteomics investigations are ongoing. Our new data from the re-discovery of the Uluzzo C Rock Shelter represent an important contribution to better understand the meaning of the Uluzzian in the context of the Middle/Upper Palaeolithic transition in south-eastern Italy.

Nutritional status of pediatric patients living with human immunodeficiency virus in Bogotá, Colombia / Nutritional status in children with HIV

Abstract Background: Undernutrition is frequent among children living with HIV in developing countries. An interaction between malnutrition and HIV pediatric infection remains incompletely characterized in Colombia. Methodology: Retrospective longitudinal study, descriptive in nature, in 28 patients with a diagnosis of HIV infection, less than 18 years of age and receiving anti retroviral therapy. Variables were retrieved from clinical records at start of antiretroviral therapy and after 12 months. Statistical analysis was exploratory. Results: 4 out of 28 patients were stunted (14,3%; 95%CI: 1,3 - 27,2), 2 out of 7 patients were wasted (28,6%; 95%CI: 0 - 62), 5 out of 17 patients were underweight (27,8%; 95%CI: 7,1 - 48,5) and 4 out of 28 patients had thinness (29,6%; 95%CI: 12,4 - 46,8). No clinically relevant anthropometric change was detected during follow-up. Anemia prevalence was 52% and 82% of patients had some degree of dyslipidemia. Both viral load (p=0,001) and CD4 count (p=0,01), significantly increased and the proportion of patients with therapeutic failure remained invariable during follow-up. Conclusion: Malnutrition is frequent and its prevalence might have decreased. HIV program improved medical control of the disease, with stable therapeutic failure rates that were comparable with previous reports. Nonetheless, anemia and dyslipidemia remain to be a paramount therapeutic challenge.

Resumen Introducción: La desnutrición es frecuente en niños con VIH en países en desarrollo. En Colombia, la interacción entre la desnutrición y la infección pediátrica por VIH se encuentra insuficientemente caracterizada. Metodología: Estudio longitudinal retrospectivo de carácter descriptivo, en 28 pacientes con diagnóstico de infección por VIH, edad menor a 18 años y con terapia antirretroviral en curso. Se extrajeron variables mediante revisión de historias clínicas en el momento de inicio de la terapia antirretroviral y 12 meses después. El análisis estadístico fue exploratorio. Resultados: 4 de 28 pacientes sufrían retraso del crecimiento (14,3%; IC95%: 1,3 - 27,2), 2 de 7 pacientes sufrían emaciación (28,6%; IC95%: 0 - 62), 5 de 17 pacientes sufrían insuficiencia ponderal (27,8%; IC95%: 7,1 - 48,5) y 4 de 28 pacientes se encontraban en delgadez (29,6%; IC95%: 12,4 - 46,8). No hubo cambios antropométricos clínicamente relevantes con el seguimiento. La prevalencia de anemia fue del 52% y 82% de los pacientes tenían algún grado de dislipidemia. Tanto la carga viral (p=0,001) como el conteo de CD4 (p=0,01), mejoraron significativamente y la proporción de pacientes con fallo terapéutico no cambió durante el seguimiento. Conclusión: La desnutrición es frecuente y su prevalencia podría haber disminuido. El programa de VIH mejoró el control médico de la enfermedad, con tasas de fallo terapéutico estables y comparables con reportes previos. No obstante, la anemia y la dislipidemia continúan siendo un gran reto terapéutico.

Síndrome de Edorexia: un posible problema mental de la autorregulación del apetito en obesidad / Edorexia syndrome: a possible mental problem of appetite autoregulation in obesity

Fundamentos: En este trabajo, se aborda el problema de la obesidad desde una perspectiva biopsicosocial. Definiendo la obesidad como una consecuencia de la autorregulación del apetito y cuyas conductas tienen una finalidad psicológica relacionada con el alivio de emociones y situaciones aversivas. Basándose en la autorregulación del apetito, se observa el Síndrome de Edorexia y se analiza su relación con la obesidad, personalidad y estilos de afrontamiento. Métodos: La muestra se constituyó por 111 individuos universitarios (29 individuos con edoréxicos y 82 sinedoréxicos) que no realizaban actividad física intensa en gimnasios y no presentaban un trastorno mental severo. Se administraron a todos los participantes el Cuestionario del Síndrome de Edorexia (CSE), el Cuestionario de Personalidad (BFQ) y el Cuestionario de Respuesta de afrontamiento (CRI-A).Resultados: Se observa que el Síndrome de Edorexia guarda relación con el abuso y evitación de los alimentos. Además, predice mejor la obesidad en comparación con otras conductas. Conclusiones: Los estudios recientes vinculan la obesidad con un problema relacionado con la autorregulación del apetito y desde este enfoque, el Síndrome de Edorexia parece ser un buen predictor de la obesidad. Según estos trabajos, la inhibición y la desinhibición del consumo de alimentos pueden ser la estrategia empleada por el organismo para solventar una situación aversiva. Por este motivo, la obesidad puede entenderse como una consecuencia del conjunto de síntomas y conductas al que se denomina Síndrome de Edorexia y resultado de una situación en la cual el individuo no dispone de otras conductas, habilidades y recursos para afrontarlo de una manera más saludable.

Background: In this article, we approach the problem of obesity from a biopsychosocial perspective. Obesity is defined as a consequence of self-regulation of appetite and such that its’ behaviors have a psychological purpose related to the relief of emotions and aversive situations. Based on self-regulation of appetite, we describe Edorexia Syndrome and we analyze its relationship with obesity, personality and coping. Methods: The sample was constituted by 111 university students (29 edorexic and 82 non-edorexic) who didn’t practice intense physical activity in gyms and didn’t present a severe mental disorder. A battery of psychological tests was applied to the whole sample. This battery consisted of Edorexia Syndrome Questionnaire (CSE), Big Five Personality Questionnaire (BFQ) and the Coping Response Inventory (CRI-A). Results: The results showed that the Edorexia Syndrome is related to the abuse and avoidance of food. It also showed that Edorexia predicts obesity better than other behaviors. Conclusions: Recent studies related obesity with a problem of self-regulation of appetite and from this perspective, Edorexia Syndrome seems to be a good predictor of obesity. According to these articles, the inhibition and disinhibition of food consumption may be the strategy used by the organism to resolve an aversive situation. For this reason, obesity can be comprehended as a consequence of the set of symptoms and behaviors called Edorexia Syndrome and the result of a situation in which the individual does not have other behaviors, skills and resources to confront it in a healthier way.

Improving the reporting quality of reliability generalization meta-analyses: The REGEMA checklist.

Reliability generalization (RG) is a meta-analytic approach that aims to characterize how reliability estimates from the same test vary across different applications of the instrument. With this purpose RG meta-analyses typically focus on a particular test and intend to obtain an overall reliability of test scores and to investigate how the composition and variability of the samples affect reliability. Although several guidelines have been proposed in the meta-analytic literature to help authors improve the reporting quality of meta-analyses, none of them were devised for RG meta-analyses. The purpose of this investigation was to develop REGEMA (REliability GEneralization Meta-Analysis), a 30-item checklist (plus a flow chart) adapted to the specific issues that the reporting of an RG meta-analysis must take into account. Based on previous checklists and guidelines proposed in the meta-analytic arena, a first version was elaborated by applying the nominal group methodology. The resulting instrument was submitted to a list of independent meta-analysis experts and, after discussion, the final version of the REGEMA checklist was reached. In a pilot study, four pairs of coders applied REGEMA to a random sample of 40 RG meta-analyses in Psychology, and results showed satisfactory inter-coder reliability. REGEMA can be used by: (a) meta-analysts conducting or reporting an RG meta-analysis and aiming to improve its reporting quality; (b) consumers of RG meta-analyses who want to make informed critical appraisals of their reporting quality, and (c) reviewers and editors of journals who are considering submissions where an RG meta-analysis was reported for potential publication.

Rodents as indicators of the climatic conditions during the Middle Pleistocene in the southwestern Mediterranean region: implications for the environment in which hominins lived.

Rodents are a very useful tool in reconstructing the environment of the past, especially owing to their rapid response to climate change, their small home range, and their restricted habitat requirements. They are a highly diverse group of mammals, which have high reproduction rates and as a result can evolve rapidly. The abundance of their microfossil remains in archaeological and paleontological sites permits robust statistical analyses to reconstruct the past climate and environment. Recently, a number of studies have affirmed the need to deepen the climatic characterization of the European Quaternary, the Middle Pleistocene being an important stage for ascertaining how our hominin ancestors lived. The aim of this study is to characterize the climatic conditions in which hominins lived in southwestern Mediterranean Europe during the Middle Pleistocene. To reconstruct these climatic conditions, we apply the bioclimatic model to rodent assemblages from Middle Pleistocene sites with human remains (Caune de l'Arago, Sima de los Huesos, Aroeira cave, Visogliano, Trinchera Galeria, and Mollet cave). Based on the percentage distribution of the species in different climate types and applying multiple linear regressions, we estimated the mean annual temperature, the mean temperature of the coldest month, and the mean temperature of the warmest month. We compared these estimates with data collected over the last 30 years from nearby meteorological stations to obtain the differences with current climate and observe the fluctuations. The climatic conditions obtained from the results of this study show that, while in Iberia mild climatic condition prevailed, in southern France and northeastern Italy harsher weather conditions were indicated.

Five-factor model of personality disorders: Spanish normative data and validation / Modelo de los cinco factores de los trastornos de personalidad: Baremo español y validación

The categorical approach of personality disorders (PD) has given way to a dimensional paradigm. Within this, the Five-factor model (FFM) proposes theoretical hypotheses describing personality pathologies and PD empirical prototypes based on the DSM (DSM-PD). Moreover, a methodology to score DSM-PD using the NEO PI-R facets was developed. In this ex post-facto study FFM-PD count norms were developed using data from the NEO PI-R Spanish adaptation. Furthermore, the diagnostic agreement with the IPDE and validity of FFM-PD counts was analyzed in a clinical (n = 222) and non-clinical sample (n = 742). Based on NEO PI-R scores, we presented Spanish FFM-PD normative data. FFMPD benchmarks were highly likely to be exceeded if subjects were classified as a subclinical case in the DSM-PD. Convergent correlations of FFM-PD counts with their equivalent subclinical cases of DSM-PD were statistically significant and outperformed any divergent correlation as well as the average divergent correlations in all FFM-PD. The use of a count technique based on NEO PI-R facets and Spanish FFM-PD normative data facilitate PD understanding and interpretation in various applied psychology fields

La concepción categórica de los trastornos de personalidad (TP) ha dado paso al paradigma dimensional, donde el modelo de los Cinco Factores (MCF) propone hipótesis teóricas para describir la patología de la personalidad y prototipos empíricos de los TP del DSM, además de técnicas para valorarlos en base a facetas del NEO PI-R. En este estudio ex post-facto se han elaborado baremos para el recuento de TP-MCF a partir de la adaptación española del NEO PI-R. Además, se ha comprobado la coherencia diagnóstica con IPDE y la validez de los recuentos de TP-MCF en una muestra clínica (n = 222) y otra no clínica (n = 742). A partir de las puntuaciones en NEO PI-R se elaboró el baremo español de los TP-MCF, cuyas cotas significativas son superadas con elevada probabilidad por casos subclínicos detectados con IPDE. Las correlaciones convergentes entre los recuentos de TP-MCF y los equivalentes casos de TP-DSM fueron estadísticamente significativas y superaron a cualquier correlación divergente y a la correlación divergente media en todos los TP-MCF. El recuento de facetas relevantes en TP-MCF y el baremo español resultante facilitan la comprensión e interpretación de los TP en distintos ámbitos de la psicología aplicada

Social contact as a strategy for self-stigma reduction in young adults and adolescents with mental health problems.

This study assessed the effectiveness of a social contact program between young adults and adolescents with and without mental health problems. It was evaluated if the development of a social contact program in a non-segregated space and respecting criteria of contact hypothesis reduced Self-Stigma and Public Stigma and, increased Self-Esteem. A pre-post intervention design was used with a sample of 47 subjects, 25 with different mental health diagnoses (Psychotic Disorder, Anxiety Disorder, Depression, Autism Spectrum Disorder and Attention Deficit Hyperactivity Disorder) and 22 without mental health problems, aged between 15 and 35 years. Five workshops of social contact and creativity were carried out during five months with a 2-h weekly meeting. The results analysis revealed a significant reduction in Self-Stigma for participants with mental health problems and may suggest a slight reduction in Public Stigma as well as a slight increase in the level of Self-Esteem of all participants. These findings suggest that programs of this nature reduce Self-Stigma and facilitate social inclusion in young adults and adolescents with and without mental health problems.

Effect of the dietary intake of melatonin- and hydroxytyrosol-rich wines by healthy female volunteers on the systemic lipidomic-related oxylipins.

Oxylipins are lipid mediators involved in the physiopathology of all organs. Moreover, isoprostanes have been established as general and reliable in vivo oxidative stress biomarkers. Red wine has proved to exert several benefits through the maintenance of the oxidative balance of the organism. Antiradical scavenging capacity has been mainly attributed to polyphenols. However, melatonin and hydroxytyrosol should be taken into account as potent antiradical agents. The present research aimed to clarify the situation of enzymatic and oxidative injury and eicosanoid urinary excretion related to the intake of three kinds of red wines and their primary musts. Judging by the reduction in the excretion of isoprostanes, red wine consumption exhibited the highest antioxidant protection against oxidative stress, attributed to its OHTyr content (p < 0.05), and to a lesser extent to its MEL content. Similarly, the intake of red wine leads to the cardioprotective effect due to the reduction in the urinary excretion of the pro-inflammatory prostaglandin 2,3-dinor-11-ß-PGF2α, besides the increase in the vasodilator prostaglandin PGE1, mediated by the melatonin (p < 0.05) and hydroxytyrosol (p < 0.05) contents. In conclusion, red wine (especially non-aged wine) exerts a higher in vivo antioxidant capacity than must or alcohol.

Sistemas de alerta temprana con enfoque participativo: un desafío para la gestión del riesgo en colombia / Early warning systems with a participative approach: a challenge for risk management in colombia

La mayor parte de la población colombiana está en condiciones de riesgo debido a factores hidroclimatológicos, fuertemente influenciados por la variabilidad (VC) y el cambio climático (CC). A esto se suma el aumento de la vulnerabilidad por la inadecuada planificación y ocupación del territorio, propia de países en desarrollo. En este sentido, los sistemas de alerta temprana (SAT) facilitan los procesos de adaptación y mitigación de impactos, por lo que se constituyen en uno de los ejes transversales de la gestión del riesgo. En este trabajo se presenta una reflexión de diversos enfoques y experiencias nacionales e internacionales en SAT. A partir de lo anterior, se identificó que muchos SAT no llegan a ser implementados; y una vez en funcionamiento, existe desequilibrio entre sus componentes. Por otro lado, no se ajustan a las necesidades de los territorios como consecuencia de la escasa participación comunitaria, tanto en la etapa de diseño como en la de operación. Por ello, se considera que para obtener resultados eficaces, que promuevan la construcción de resiliencia, son necesarios SAT con enfoque participativo, que fortalezcan las capacidades de las comunidades para enfrentar las condiciones de riesgo de su entorno.

Most of the Colombian population is facing risks due to hydroclimatological factors, strongly influenced by the climate variability (CV) and climate change (CC). Likewise, vulnerability is continuously increasing because of inadequate land planning and occupation, common in developing countries. Therefore, early warning systems (EWS) facilitate the processes of adaptation and mitigation of impacts, which is why they constitute one of the transverse axes in risk management. This study aimed to review approaches to and field experiences with EWS throughout the world, including Colombia. We identified that many EWS are unimplemented; and once in operation, there exists an imbalance among components. On the other hand, some EWS fail to meet the territory needs as a result of poor community participation, both at design and operation stages. Hence, a participative approach in EWS to tackling risks and building up the capacities of the communities should be promoted for obtaining effective results.

Understanding the emergence of modern humans and the disappearance of Neanderthals: Insights from Kaldar Cave (Khorramabad Valley, Western Iran).

Kaldar Cave is a key archaeological site that provides evidence of the Middle to Upper Palaeolithic transition in Iran. Excavations at the site in 2014-2015 led to the discovery of cultural remains generally associated with anatomically modern humans (AMHs) and evidence of a probable Neanderthal-made industry in the basal layers. Attempts have been made to establish a chronology for the site. These include four thermoluminescence (TL) dates for Layer 4, ranging from 23,100 ± 3300 to 29,400 ± 2300 BP, and three AMS radiocarbon dates from charcoal samples belonging to the lower part of the same layer, yielding ages of 38,650-36,750 cal BP, 44,200-42,350 cal BP, and 54,400-46,050 cal BP (all at the 95.4% confidence level). Kaldar Cave is the first well-stratified Late Palaeolithic locality to be excavated in the Zagros which is one of the earliest sites with cultural materials attributed to early AMHs in western Asia. It also offers an opportunity to study the technological differences between the Mousterian and the first Upper Palaeolithic lithic technologies as well as the human behaviour in the region. In this study, we present a detailed description of the newly excavated stratigraphy, quantified results from the lithic assemblages, preliminary faunal remains analyses, geochronologic data, taphonomic aspects, and an interpretation of the regional paleoenvironment.

An explanatory model of underwater adaptation / Un modelo explicativo de la adaptación subacuática

The underwater environment is an extreme environment that requires a process of human adaptation with specific psychophysiological demands to ensure survival and productive activity. From the standpoint of existing models of intelligence, personality and performance, in this explanatory study we have analyzed the contribution of individual differences in explaining the adaptation of military personnel in a stressful environment. Structural equation analysis was employed to verify a model representing the direct effects of psychological variables on individual adaptation to an adverse environment, and we have been able to confirm, during basic military diving courses, the structural relationships among these variables and their ability to predict a third of the variance of a criterion that has been studied very little to date. In this way, we have confirmed in a sample of professionals (N = 575) the direct relationship of emotional adjustment, conscientiousness and general mental ability with underwater adaptation, as well as the inverse relationship of emotional reactivity. These constructs are the psychological basis for working under water, contributing to an improved adaptation to this environment and promoting risk prevention and safety in diving activities

El medio subacuático constituye un entorno extremo que exige un proceso de adaptación humana con demandas psicofisiológicas específicas para garantizar la supervivencia y la actividad productiva. En este trabajo explicativo se analiza, bajo la óptica de los actuales modelos de inteligencia, personalidad y rendimiento, la contribución de las diferencias individuales para explicar la adaptación de personal militar en un entorno estresante. Se verifica, mediante análisis de ecuaciones estructurales, un modelo donde se contemplan los efectos directos de las variables psicológicas sobre la adaptación personal a un medio adverso, comprobando sus relaciones estructurales durante la realización de cursos básicos de buceo militar y su capacidad para predecir un tercio de la varianza de un criterio poco estudiado. De esta manera, se confirma en una muestra de profesionales (N = 575) la relación directa de ajuste emocional, responsabilidad y habilidad mental general con la adaptación subacuática, atribuyendo una relación inversa a reactividad emocional. Estos constructos constituyen el fundamento psicológico para desenvolverse con seguridad y trabajar bajo el agua, contribuyen a la mejora de la adaptación al medio subacuático y favorecen la prevención de riesgos y la seguridad en las actividades de buceo

Incremental Validity of Personality Measures in Predicting Underwater Performance and Adaptation.

Intelligence and personality traits are currently considered effective predictors of human behavior and job performance. However, there are few studies about their relevance in the underwater environment. Data from a sample of military personnel performing scuba diving courses were analyzed with regression techniques, testing the contribution of individual differences and ascertaining the incremental validity of the personality in an environment with extreme psychophysical demands. The results confirmed the incremental validity of personality traits (ΔR 2 = .20, f 2 = .25) over the predictive contribution of general mental ability (ΔR 2 = .07, f 2 = .08) in divers' performance. Moreover, personality (R(L)2 = .34) also showed a higher validity to predict underwater adaptation than general mental ability ( R(L)2 = .09). The ROC curve indicated 86% of the maximum possible discrimination power for the prediction of underwater adaptation, AUC = .86, p < .001, 95% CI (.82-.90). These findings confirm the shift and reversal of incremental validity of dispositional traits in the underwater environment and the relevance of personality traits as predictors of an effective response to the changing circumstances of military scuba diving. They also may improve the understanding of the behavioral effects and psychophysiological complications of diving and can also provide guidance for psychological intervention and prevention of risk in this extreme environment.

Chronological and environmental context of the first hominin dispersal into Western Europe: The case of Barranco León (Guadix-Baza Basin, SE Spain).

The early Pleistocene site of Barranco León (Guadix-Baza Basin, SE Spain), dated to 1.4 Ma (millions of years ago), records the oldest hominin occurrence in Western Europe, as evidenced by the discovery of one tooth and thousands of Mode 1 stone tools. In this paper a detailed analysis of the microvertebrate content of the D1 and D2 units from this site is presented. The early Pleistocene in the Guadix-Baza Basin is characterized by a sharp climatic deterioration, which possibly impeded the settlement of this region by the early hominin population from the southern Caucasus. Shortly afterwards, when the climatic conditions were again favorable, a hominin presence is suddenly evidenced at the units D1 and D2 of Barranco León. According to the microvertebrate analysis of these units, the mean annual temperature at the time of deposition was significantly higher than 13 °C, with prevalent humid conditions. However, although most of the species were inhabitants of water edges, an open landscape was present in the vicinity of the lake. The data reported here clearly support the idea that the early hominin occupation of Europe was strongly constrained by climatic and environmental conditions, rather than by physiography or cultural factors.

Pensamiento constructivo como medida de inteligencia emocional en patología dual / No disponible

Introducción: El objetivo de este estudio es comparar el pensamiento constructivo, una medida de inteligencia emocional, entre una muestra clínica de pacientes adultos diagnosticados de patología dual y una muestra no clínica. Método: Mediante un diseño de investigación comparativo, una muestra no clínica de 835 sujetos se comparó con una muestra de 180 sujetos diagnosticados de patología dual: 78 con trastornos clínicos o del Eje I y102 con trastornos de la personalidad o del Eje II, según criterios DSM-IV-TR. Resultados: Los resultados indican un pensamiento constructivo superior en la muestra no clínica, así como un pensamiento destructivo superior en la muestra con patología dual. No se apreciaron diferencias entre trastornos clínicos y de personalidad. Conclusiones: La muestra clínica presenta un patrón destructivo o desadaptativo de afrontamiento en comparación con población no clínica, que en el caso de pacientes con trastornos de personalidad se ve incrementado por ilusiones, supersticiones y pensamientos esotéricos que contribuyen a su afrontamiento deficitario

Introduction: The objective of this study is to compare the constructive thinking, a measure of emotional intelligence, between a clinical sample of adult patients diagnosed with dual diagnosis and a non-clinical sample. Method: By means of a comparative design of investigation, a not clinical sample of 835 subjects was compared with a sample of 180 subjects diagnosed of dual diagnosis: 78 with clinical disorders or of the Axix I and 102 with disorders of the personality or of the Axis II, according to DSM-TR-IV. Results: The results indicate a constructive thinking greater than in the non-clinical sample, as well as a destructive thinking higher in the sample with dual diagnosis. There were no differences between clinical disorders and personality. Conclusions: The clinic sample presents a destructive pattern of coping or no adaptative compared with non-clinical population, which in the case of patients with personality disorders is increased by illusions and superstitions and esoteric thoughts that contribute to their coping deficit

Pleistocene history of Iberomys, an endangered endemic rodent from southwestern Europe.

The extant Cabrera's vole, Microtus cabrerae, differs in morphology and evolutionary history from the other species of Microtus. This arvicoline has unique derived features in the cranium, mandible and dentition. Probably its most conspicuous features are its large size, the high skull in lateral view, the long and distally broad nasals, and the triangle shape of the anteroconid complex, with a marked labio-lingual asymmetry of the occlusal surface of the first lower molars. In this study, we propose a phylogenetic lineage that includes Cabrera's vole in what until now has been the Microtus subgenus Iberomys. Paleontological information and several life history traits support the elevation of Iberomys to the rank of genus. Genus Iberomys comprises species that have appeared in succession during the Quaternary: in the Early Pleistocene, the extinct I. huescarensis in the Middle Pleistocene, the extinct I. mediterraneus and in the Late Pleistocene, the extant I. cabrerae. Interestingly, the extant species shows several biological singularities, such as multiple polymorphic copies of the SRY male-specific gene in both males and females, and the lowest basal metabolic rate in relation to weight among arvicoline species. Likewise, its habitat requirement is unique among the Iberian arvicolines. Accordingly, the biological and paleontological data that we present in this work support the elevation of its taxonomic rank to that of genus. This study also suggests a modification of nomenclature: Microtus (Iberomys) brecciensis is replaced with I. mediterraneus and the common name of the extant M. (I.) cabrerae changed from 'topillo' to 'iberon' to improve conservation and protection actions.

Prediction of human adaptation and performance in underwater environments / Predicción de la adaptación y rendimiento humanos en el medio subacuático

BACKGROUND: Environmental stressors require the professional diver to undergo a complex process of psychophysiological adaptation in order to overcome the demands of an extreme environment and carry out effective and efficient work under water. The influence of cognitive and personality traits in predicting underwater performance and adaptation has been a common concern for diving psychology, and definitive conclusions have not been reached. METHOD: In this ex post facto study, psychological and academic data were analyzed from a large sample of personnel participating in scuba diving courses carried out in the Spanish Navy Diving Center. In order to verify the relevance of individual differences in adaptation to a hostile environment, we evaluated the predictive validity of general mental ability and personality traits with regression techniques. RESULTS: The data indicated the existence of psychological variables that can predict the performance (R2 = .30, p<.001) and adaptation (R2N= .51, p<.001) of divers in underwater environment. CONCLUSIONS: These findings support the hypothesis that individual differences are related to the probability of successful adaptation and effective performance in professional diving. These results also verify that dispositional traits play a decisive role in diving training and are significant factors in divers' psychological fitness

ANTECEDENTES: los estresores ambientales exigen al buceador profesional un complejo proceso de adaptación psicofisiológica para superar las demandas de un medio extremo y desarrollar trabajos subacuáticos efectivos. La influencia de los rasgos cognitivos y de personalidad para predecir la adaptación y el rendimiento ha constituido una preocupación constante en Psicología del buceo, aunque no se han alcanzado conclusiones definitivas. MÉTODO: en este estudio ex post facto se analizaron datos psicológicos y académicos de personal que realiza cursos de buceo en el Centro de Buceo de la Armada Española. Con el fin de verificar la relevancia de las diferencias individuales en la adaptación a un ambiente hostil, hemos evaluado la validez predictiva de la inteligencia y personalidad mediante técnicas de regresión. RESULTADOS: los datos obtenidos indicaron la existencia de variables psicológicas útiles para predecir el rendimiento (R2 = .30, p<.001) y la adaptación (R2N = .51, p<.001) en el medio subacuático. CONCLUSIONES: estos hallazgos confirman la hipótesis de que las diferencias individuales guardan relación con la probabilidad de obtener una satisfactoria adaptación y rendimiento efectivo en buceo profesional, tienen un papel decisivo en la formación de buceadores y son factores significativos en su aptitud psicológica
