Abstract.Objective. To determine the inter-gender differences in dispositional optimism, depression, anxiety, and stress; as well as the predictive role of optimism on pathological features in a sample of Ecuadorian university students. Method. This is a descriptive, comparative, predictive and cross-sectional study using the Life Orientation (LOT-R) and Depression, Anxiety and Stress Scale (DASS-21) tests with 288 university students belonging to one university of Ambato; 63.9% women, 31% men aged between 17 to 39 (M = 21.6 years, SD = 2.5). Results. Gender differences were found at the Anxiety and Stress level, with greater presence in women than in men. As regards dispositional optimism and depression, gender is invariant. There were both slight and significant correlations between dispositional optimism and the dimensions evaluated by the DASS 21 test. Dispositional optimism also explains changes in variance in depression (15.2%), anxiety (9.7%) and stress (5.5%). As a conclusion, dispositional optimism is a relevant predictor of depression, as well as anxiety and stress in university students.

Niveles de Optimismo: Diferencias entre adultos de países latinoamericanos / Levels of Optimism: Differences between adults in Latin American countries

Resumen El optimismo disposicional es la variable dentro de la Psicología Positiva que más se ha estudiado en distintos entornos, pues se presenta como relacionada y predictora de otras variables y entornos de salud. El presente estudio se dedicó a conocer si existían diferencias significativas en los niveles de Optimismo medidos a través del Life Orientation Test (LOT-R) en función del país de residencia que tenían las personas, en una muestra accidental de 464 personas de Argentina, México y Chile. No se encontraron diferencias significativas en la dimensión Optimismo pero sí en la dimensión Pesimismo, en donde Argentina presenta los mayores niveles. Además, se detectaron diferencias significativas en 2 de los ítems de la dimensión Optimismo, en la que los residentes mexicanos presentaban mejores niveles, y en un ítem de la dimensión Pesimismo. Los resultados son limitados al estudio que se realizó, pero destacan la importancia de realizar más estudios en temas que los gobiernos actuales están trabajando para mejorar la calidad de vida de las personas, que puede estar directamente influenciada por variables positivas como el Optimismo.

Abstract Dispositional optimism is the variable within Positive Psychology that has been studied in different environments, as it is presented as related and predictor of psychological variables and health environments. The present study investigated whether there were significant differences in Optimism levels measured through the Life Orientation Test (LOT-R) according to the country of residence of the people, in an accidental sample of 464 people from Argentina, Mexico and Chile. No significant differences were found in the Optimism dimension, but in the Pessimism dimension, where Argentina presents the highest levels. In addition, significant differences were detected in 2 of the items in the Optimism dimension, where Mexican residents presented themselves with better levels, and in an item of the dimension Pessimism. The results are limited to the study that was carried out but they emphasize the importance of carrying out more studies in subjects that the present governments are working to improve the quality of life of the people that can be directly influenced by positive variables like Optimism.

Psychometric properties of the Life Orientation Test (LOT-R) and its relationship with psychological well-being and academic progress in college students / Propiedades psicométricas del Life Orientation Test (LOT-R) y su relación con el bienestar psicológico y el progreso académico en estudiantes universitarios

Abstract The aim of this study is to analyze the dimensionality of the Spanish version of the Revised Life Orientation Test (LOT-R), to examine the relationship between psychological well-being and dispositional optimism/pessimism in a sample of college students (n = 291), as well as to consider the effect of dispositional optimism/pessimism on academic progress. The results indicated that the properties of the Spanish version of the LOT-R (a= .72) were very similar to the original. The questionnaire clearly presented two partially independent factors, and the items assessing optimism demonstrated greater discriminant validity than the items assessing pessimism. Optimism was positively linked to psychological well-being and negatively related to psychological-distress. In the male students, a certain degree of preoccupation about academic results was linked to progress in studies, while excessive worry about academic progress could obstruct the successful completion of studies in the female students. These results suggest that the LOT-R can be used as a reliable and valid tool for the analysis of optimism and its positive effects on health and academic progress.

Resumen Este estudio pretende analizar la dimensionalidad de la versión española del Revised Life Orientation Test, para examinar la relación entre el bienestar psicológico y el optimismo/pesimismo disposicional en una muestra de estudiantes universitarios (n = 291) y analizar la repercusión del optimismo/pesimismo disposicional en el progreso académico. Los resultados indican que las propiedades de la versión española del Revised Life Orientation Test (a = 0.72) son muy similares a los de la versión original. El test presenta una estructura clara con dos factores parcialmente independientes, los ítems del factor optimismo tienen un poder discriminatorio mayor que los del factor de pesimismo. El optimismo está relacionado positivamente con el bienestar psicológico y negativamente con el malestar psicológico. En hombres, cierto grado de preocupación por los resultados académicos estaría relacionado con el progreso académico en los estudios, mientras que en mujeres, una excesiva preocupación académica podría ser perjudicial para finalizar con éxito los estudios. Estos resultados sugieren que el Revised Life Orientation Test puede ser un instrumento fiable y válido para analizar el optimismo y su relación con la salud y progreso académico.

AUTOESTIMA Y DESESPERANZA EN ADOLESCENTES DE UNA INSTITUCIÓN EDUCATIVA DEL QUINDÍO / ESTEEM AND HOPELESSNESS IN ADOLESCENTS IN AN EDUCATIONAL INSTITUTION OF QUINDÍO

Esta es una investigación empírico-analítica de tipo correlacional cuya intención es hallar la relación entre niveles de autoestima y desesperanza en 224 adolescentes de los grados 9º, 10º y 11º de bachillerato de una institución educativa pública del departamento del Quindío. Se aplicó la escala de Desesperanza de Beck y el inventario de autoestima de Rosenberg. Se encontró que el Riesgo de Suicidio o grado de Desesperanza "ninguno o mínimo" fue del 59,4%, el riesgo leve 26,8%, moderado 12,9% y alto 0,9%. El riesgo mínimo en mujeres fue del 33,5% y alto del 0,9%, mientras en los hombres prevalece el riesgo mínimo 29,5%, leve 17% y moderado 7,1%. La desesperanza se incrementa en los adolescentes por factores motivacionales y cognitivos que dan forma a la ideación suicida y elevan los riesgos de suicidio. La autoestima baja no es un factor consistente en la ideación suicida.

This is an empirical-analytic correlational research whose intent is to find the relationship between levels of self-esteem and hopelessness in adolescents in an educational institution of Quindío-Colombia. The Beck Hopelessness Scale and the Self-Esteem Scale Rosenberg were applied. It was found that the risk of suicide or grade of hopelessness "none or minimal" is 59.4%, "mild" 26.8%, "moderate" 12.9% and "high" 0.9%. The type of suicide risk is minimal in women 33.5% and high 0.9 %, while in the men is minimal 29.5 %, mild 17 %, and moderate 7.1%. Expressing as conclusion that hopelessness is increase for motivational and cognitive factors that shape suicidal ideation and raise the risk of suicide. Low self-esteem is not a consistent factor in suicidal ideation.

The Mediating Role of Optimism and Pessimism on the Relationship between Spirituality and Depression among Elderly Cancer Patients

BACKGROUND: Numerous studies have demonstrated that spirituality has protective effects on depression. However, there are only few studies on the theoretical mechanism showing how spirituality effects on depression. Thus, to find mediating variables explaining the relationship between the spirituality and depression may help to develop appropriate program for reducing depression in elderly cancer patients. In this study, we examined the effect of optimism and pessimism as their mediating effects on depression. METHODS: This study is to verify the relationships between spirituality and depression along with the mediating effects of optimism and pessimism among 600 South Korean elderly cancer patients who participated in a community-based study about their mental health. RESULTS: Optimism and pessimism are linked with spirituality and depression. Higher spirituality levels were associated with increased optimistic thinking, and then optimistic thinking is associated with low possibility of depression, whereas lower spirituality levels were associated with more pessimistic thinking, and in turn pessimistic thinking is associated with high depression scores. CONCLUSIONS: Understanding optimism and pessimism affecting depression level is critical for developing spirituality-based programs to reduce depression in elderly cancer patients.

Effects of adult attachment and life orientation style on job burnout among nurses / 中华行为医学与脑科学杂志

Objective To explore the relationship of adult attachment,life orientation style and job burnout among nurses.Methods Relationship Questionnaire (RQ) and Experience of close relationships (ECR) inventory were used to measure 566 nurses' adult attachment.Life orientation test (LOT-R) and Maslach's Burnout Inventory-General Scale (MBI-GS) were administrated to measure subjects'optimism,pessimism,and job burnout.Results ①Distribution of adult attachment style in nurses were 36％ for secure,29.3％ for dismissing,18.4％for preoccupied and 6.7％ for fearful.②Attachment avoidance were positive correlated with pessimism (r =0.139) and negative correlated with optimism (r =-0.212) significantly; and there was significant positive correlation between attachment avoidance and ineffectiveness (r=0.122) also.Attachment anxiety was positively related to pessimism (r=0.151),and three indexes of job burnout (r=0.238,0.281,0.143 respectively).Meanwhile,there were significant negative correlations among optimism and job burnout indexes (r =-0.12,-0.193,-0.230).③There were significant differences among four attachment groups on optimism and pessimism.For job burnout,the four groups had significant differences only on depersonalization,instead of ineffectiveness and emotion exhaustion.④ Regression analysis suggested that attachment anxious was a valid positive predictor of job burnout,while optimism was a negative predictor.Conclusion Both adult attachment and life orientation style are contributed to job burnout among nurses.

The Neural Basis of Optimism and Pessimism

Our survival and wellness require a balance between optimism and pessimism. Undue pessimism makes life miserable; however, excessive optimism can lead to dangerously risky behaviors. A review and synthesis of the literature on the neurophysiology subserving these two worldviews suggests that optimism and pessimism are differentially associated with the two cerebral hemispheres. High self-esteem, a cheerful attitude that tends to look at the positive aspects of a given situation, as well as an optimistic belief in a bright future are associated with physiological activity in the left-hemisphere (LH). In contrast, a gloomy viewpoint, an inclination to focus on the negative part and exaggerate its significance, low self-esteem as well as a pessimistic view on what the future holds are interlinked with neurophysiological processes in the right-hemisphere (RH). This hemispheric asymmetry in mediating optimistic and pessimistic outlooks is rooted in several biological and functional differences between the two hemispheres. The RH mediation of a watchful and inhibitive mode weaves a sense of insecurity that generates and supports pessimistic thought patterns. Conversely, the LH mediation of an active mode and the positive feedback it receives through its motor dexterity breed a sense of confidence in one's ability to manage life's challenges, and optimism about the future.

Pesimismo freudiano: salud mental y malestar en la cultura / Pessimismo freudiano: saúde mental e o mal estar na civilização / Freudian pessimism: mental health e discontent in civilization / Le pessimisme freudien: santé mentale et malaise dans la culture

Las relaciones entre el psicoanálisis y el pensamiento social hunden sus raíces en los primeros desarrollos del descubrimiento freudiano. El propio Freud no es ajeno a esta cuestión y después de la Primera Guerra Mundial dedica una parte significativa de su producción a los llamados textos sociológicos. Tanto la teoría social como la concepción pulsional en sus últimas elaboraciones representan el equipaje más comprometedor de la herencia freudiana, que sólo algunos autores como Jacques Lacan están dispuestos a retornar. El llamado pesimismo freudiano asociado a estos textos critica la lectura optimista de la metáfora poder-expresión que establece la acción unilateral del poder sobre algo que queda imposibilitado de expresarse libremente. Es desde estas coordenadas que pretendemos adentrarnos en la concepción freudiana de salud mental. El hecho de que la ley no sea tan enemiga de la pulsión, que la ley no esté depurada de la satisfacción patológica, tendrá importantes efectos para la retórica de la liberación personal y política.

As relações entre a psicanálise e o pensamento social têm suas raízes nos primeiros passos da descoberta freudiana. O próprio Freud não é alheio a esta questão e após a Primeira Guerra Mundial dedica uma parte significativa de sua produção aos chamados textos sociológicos. Tanto a teoria social como o conceito de pulsão em suas últimas elaborações representam a bagagem mais comprometedora da herança freudiana, que somente alguns autores como Jacques Lacan estão dispostos a retomar. O chamado pessimismo freudiano associado a esses textos critica a leitura otimista da metáfora poder-expressão que estabelece a ação unilateral do poder sobre algo que fica impossibilitado de se expressar livremente. É a partir destas coordenadas que pretendemos adentrar na concepção freudiana de saúde mental. O fato de que a lei não seja tão inimiga da pulsão e que não está livre da satisfação patológica, terá efeitos importantes na retórica da liberação pessoal e política.

The relations between psychoanalysis and social thought find their roots in the early developments of Freud's work. He took on this question and dedicated a considerable part of his production on the so-called sociological texts, published after the World War I. Social theory and his final conception of the drives represent the most compromising aspects of Freud's inheritance, to which only a few authors, such as Jacques Lacan, have been willing to return. Freud takes a pessimistic view in these texts and criticizes the optimistic reading of the metaphor of power-expression, which establishes the unilateral action of power on something that cannot be expressed freely. It is from these coordinates that the author of this article endeavors to update the Freudian conception of mental health and explore how the law is in a paradoxical relationshipwith the drives and with pathological satisfaction. This conception has important effects for the rhetoric of personal and political liberation.

Les rapports entre la psychanalyse et la pensée sociale remontent au début du développement de la découverte freudienne. Freud lui-même en est conscient et après la Première Guerre mondiale, il consacre une partie importante de sa production aux textes que certains appellent culturels. Autant la théorie sociale que la conception de pulsion représentent les bagages les plus compromettants de l'héritage freudien que seuls quelques auteurs comme Jacques Lacan sont prêts à reprendre. Le pessimisme freudien associé à ces textes critique la lecture optimiste de la métaphore puissance-expression qui établit l'action unilatérale de la puissance sur quelque chose qui est incapable de s'exprimer librement. C'est à partir de ces coordonnées que l'article sonde la conception freudienne de la santé mentale. Le fait que la loi n'est pas l'ennemie absolue de la pulsion et qu'elle n'est pas exemptée de la satisfaction pathologique produira d'importantes répercussions sur la rhétorique de la libération personnelle et politique.
