The Role of Attachment in a Social Cognitive Model of Social Domain Satisfaction in College Students

The study examined a modified social cognitive model of domain satisfaction (Lent, 2004). In addition to social cognitive variables and trait positive affect, the model included two aspects of adult attachment, attachment anxiety and avoidance. The study extended recent research on well-being and satisfaction in academic, work, and social domains. The adjusted model was tested in a sample of 454 college students, in order to determine the role of adult attachment variables in explaining social satisfaction, above and beyond the direct and indirect effects of trait positive affect. Confirmatory factor analysis found support for 8 correlated factors in the modified model: social domain satisfaction, positive affect, attachment avoidance, attachment anxiety, social support, social self-efficacy, social outcome expectations, and social goal progress. Three alternative structural models were tested to account for the ways in which attachment anxiety and attachment avoidance might relate to social satisfaction. Results of model testing provided support for a model in which attachment avoidance produced only an indirect path to social satisfaction via self-efficacy and social support. Positive affect, avoidance, social support, social self-efficacy, and goal progress each produced significant direct or indirect paths to social domain satisfaction, though attachment anxiety and social outcome expectations did not contribute to the predictive model. Implications of the findings regarding the modified social cognitive model of social domain satisfaction were discussed.

Cyberbullying: competencia social, motivación y relaciones entre iguales

El reconocimiento de cierto solapamiento entre el acoso cara a cara (bullying) y el ciberacoso (cyberbullying) puede indicar que variables de cognición social, cuya influencia ha sido reconocida en el bullying, también estén presentes en el acoso cibernético. El objetivo de la investigación fue estudiar el ajuste social de los implicados en cyberbullying y analizar las diferencias en la percepción de la competencia social, la motivación y el apoyo de los iguales, entre víctimas, agresores y agresores victimizados del cyberbullying. Un total de 505 adolescentes (47,3% chicas) con edades comprendidas entre los 12 y 16 años (M=13.95; DT=1.42) participaron en el estudio. Se utilizaron instrumentos para adolescentes validados en español y se analizaron las propiedades psicométricas para la adaptación de la escala de competencia social. Análisis factoriales exploratorios y confirmatorios mostraron índices óptimos de fiabilidad y validez. Se observó una mayor implicación de los ciberagresores victimizados. Las comparaciones entre roles a través de pruebas no paramétricas mostraron en los ciberagresores un mayor apoyo social que el resto de perfiles y altos niveles en metas de popularidad. Las cibervíctimas destacaron por su alta percepción de competencia social. Los ciberagresores victimizados mostraron altos niveles de metas de popularidad y baja aceptación social. Los resultados obtenidos permiten concluir que la forma en que el grupo de iguales gestiona su vida emocional y social puede estar explicando la situación de cyberbullying entre los adolescentes.

The Impact of Motor Learning on Motor Behavior and Cortical Dynamics in a Complex Stressful Social Environment

An economy of effort is a core characteristic of highly skilled motor performance often described as being effortless or automatic. Electroencephalographic (EEG) evaluation of cortical activity in elite performers has consistently revealed a reduction in extraneous associative cortical activity and an enhancement of task-relevant cortical processes. However, this has only been demonstrated under what are essentially practice-like conditions. Recently it has been shown that cerebral cortical activity becomes less efficient when performance occurs in a stressful, complex social environment. This dissertation examines the impact of motor skill training or practice on the EEG cortical dynamics that underlie performance in a stressful, complex social environment. Sixteen ROTC cadets participated in head-to-head pistol shooting competitions before and after completing nine sessions of skill training over three weeks. Spectral power increased in the theta frequency band and decreased in the low alpha frequency band after skill training. EEG Coherence increased in the left frontal region and decreased in the left temporal region after the practice intervention. These suggest a refinement of cerebral cortical dynamics with a reduction of task extraneous processing in the left frontal region and an enhancement of task related processing in the left temporal region consistent with the skill level reached by participants. Partitioning performance into ‘best’ and ‘worst’ based on shot score revealed that deliberate practice appears to optimize cerebral cortical activity of ‘best’ performances which are accompanied by a reduction in task-specific processes reflected by increased high-alpha power, while ‘worst’ performances are characterized by an inappropriate reduction in task-specific processing resulting in a loss of focus reflected by higher high-alpha power after training when compared to ‘best’ performances. Together, these studies demonstrate the power of experience afforded by practice, as a controllable factor, to promote resilience of cerebral cortical efficiency in complex environments.

COSTA RICA EN LA ENCRUCIJADA: LOS LÍMITES DEL AJUSTE ESTRUCTURAL Y LOS URGENTES DESAFÍOS DE LA REFORMA ECONÓMICA Y SOCIAL

Aunque en Costa Rica no se ha seguido en los últimos quince años una política económica neoliberal a ultranza, sino una “a la tica”; todo el debate económico y el accionar del sector público durante este período ha sido permeable a la lógica del ajuste estructural. Pero la actual encrucijada obliga a “tirios y troyanos”, a críticos y defensores del ajuste, a superar este enfoque aún predominante. Independientemente de los logros y fracasos acumulados desde 1983 hasta la fecha, en el campo económico y social, el país debe, urgentemente, realizar un “viraje estratégico”, pues la sensación de estancamiento o lento crecimiento de los últimos años se ha convertido en cruda realidad, con el agravante de que ya no podemos seguir viviendo del pasado. En el texto se aborda la problemática nacional en las siguientes cinco áreas:Estabilidad macroeconómica: sin ser artificial, continúa siendo frágil, dependiente en alto grado de la entrada de capitales externos y arrastrando una crisis fiscal latente que recurrentemente estalla. Esto en gran parte se explica por los rasgos de inestabilidad estructural que aun persisten.Gobernabilidad y Reforma del Estado: el estilo de gobernabilidad moldeada durante el período 1950-1975 ya no es viable, y la vacilante reforma del Estado está contribuyendo solo de manera precaria a construir nuevas formas de gobernabilidad acordes con las exigencias de las modernas sociedades democráticas. La gran tarea por delante es reconstruir un Estado estratégico y solidario; que facilite la irrupción de la sociedad civil en la vida pública nacional.Transformación productiva y competitividad: avanza, pero sin un rumbo claro y seguro, pues se adolece de una estrategia nacional de desarrollo de la competitividad internacional, que supere prácticas anticuadas de intervención estatal y viejos pero maquillados dogmas antiestatales que conducen a visiones parciales sobre el papel de las empresas y del Estado en este tipo de estrategias.El modelo exportador y el papel de la inversión extranjera: su impresionante dinamismo de los últimos años “suma” pero no “multiplica” la creación de riqueza nacional. Faltan criterios estratégicos que permitan potenciar los efectos positivos de la IED sobre el aparato productivo nacional y la creación de empleos de alta calidad, evitando que la misma promueva modelos de exportación tipo enclaves.Los recursos humanos y el sistema educativo: a pesar de que existe un alto consenso de que el conocimiento será el principal “factor de producción” del futuro y la fuente más importante de la competitividad de empresas y países; el sistema educativo costarricense enfrenta serias amenazas y debilidades que impiden convertirlo en el valuarte de la transformación productiva y social que el país requiere, en pos de lograr un mayor desarrollo humano.A partir de este diagnóstico surgen una serie de tareas y desafíos que como país podemos enfrentar exitosamente, si dejamos atrás dogmas económicos obsoletos y si superamos la incapacidad de construir grandes acuerdos nacionales. No hacerlo sería condenarnos a un eterno subdesarrollo. El documento termina con un pedido para dejar atrás definitivamente la era del ajuste estructural y relanzar una nueva era de desarrollo productivo, social y humano.

Contributos para a adaptação e aferição de duas medidas de suporte social

"A perceção de suporte social familiar e dos amigos tem uma grande influência no desenvolvimento psicossocial saudável dos adolescentes. Desta forma, propusemo-nos adaptar e aferir para a população portuguesa as escalas de medida Perceção do Suporte Social da Família (PSS-Fam) e dos Amigos (PSS-Am) de Procidado e Heller (1983). Apresentamos os resultados obtidos a partir de uma amostra de 851 adolescentes com idades compreendidas entre os 11 e os 19 anos. Os resultados estão de acordo com os obtidos por Procidano e Heller (1983) que obtiveram uma solução com apenas um fator para cada escala. Os estudos psicométricos revelam, de forma global, bons índices de fiabilidade e validade dos instrumentos. Concluímos contribuindo com duas medidas adequadas para avaliar o suporte social percebido na população adolescente."

The effects of the quality of social relationships and emotion regulation ability on the happiness of introvert individuals

Previous research has shown that extraverts are happier than introverts and, although happy introverts exist, it is unclear under what conditions they can achieve happiness. The aim of the present study is to analyze the quality of social relationships and emotion regulation ability as a possible factor for happiness in introvert individuals. 1006 adults (42% males) completed measures of extraversion, neuroticism, quality of social relationships, emotion regulation ability and happiness. Results shows that introverts have significantly lower happiness, quality of life, quality of social relationship and emotion regulation ability scores than extraverts. Besides, those individuals with high quality social relationships or high emotion regulation ability were happier. Introverts were happier when they had high scores for quality of social relationships and emotion regulation ability, however the effect size was small. These results suggest that emotion regulation and social relationships are important to understand the relationships between introversion and happiness.

Factor structure of the General Health Questionnaire-28 (GHQ-28) from infertile women attending the Yazd Research and Clinical Center for Infertility

Background: Nowadays, infertility problems have become a social concern, and are associated with multiple psychological and social problems. Also, it affects the interpersonal communication between the individual, familial, and social characteristics. Since women are exposed to stressors of physical, mental, social factors, and treatment of infertility, providing a psychometric screening tool is necessary for disorders of this group. Objective: The aim of this study was to determine the factor structure of the general health questionnaire-28 to discover mental disorders in infertile women. Materials and Methods: In this study, 220 infertile women undergoing treatment of infertility were selected from the Yazd Research and Clinical Center for Infertility with convenience sampling in 2011. After completing the general health questionnaire by the project manager, validity and, reliability of the questionnaire were calculated by confirmatory factor structure and Cronbach's alpha, respectively. Results: Four factors, including anxiety and insomnia, social dysfunction, depression, and physical symptoms were extracted from the factor structure. 50.12% of the total variance was explained by four factors. The reliability coefficient of the questionnaire was obtained 0.90. Conclusion: Analysis of the factor structure and reliability of General Health Questionnaire-28 showed that it is suitable as a screening instrument for assessing general health of infertile women.

Comunicación para la inclusión social de minorías. La Clase Mágica, un modelo de intervención para el cambio social

Las minorías culturales y étnicas son con frecuencia los grupos más desfavorecidos en términos sociales y económicos debido a su falta de representación institucional. El objetivo de este artículo es proponer un modelo de intervención capaz de aumentar el poder de participación de una minoría a través de la comunicación horizontal con otras identidades mayoritarias. Los resultados del estudio de caso del programa socioeducativo La Clase Mágica, para el que se utiliza una metodología eminentemente cuantitativa a partir de cuestionario, demuestran que estos aspectos contribuyen a que los mexicanos de primera y segunda generación en el sur de California desarrollen capacidades clave para el empoderamiento y la inclusión social. Además, el programa impactó en un factor determinante para que una comunidad consiga ganar poder de acción y voz suficiente para influir en las instituciones sociales: los apoyos externos.

MIGRATION PATTERNS AMONG YOUNG ADULTS IN THE UNITED STATES: ENVIRONMENTAL, SOCIAL, AND ECONOMIC EXPLANATIONS

Young adult migration is a key factor in community development. The goal of this paper is to study what kinds of places attract young adults and what kinds are losing them. Linear regression is conducted to analyze what place-specific factors explain migration patterns among young adults. These factors include economic, social, and environmental variables. This study finds that social and environmental factors are just as important as economic ones. Specifically, employment in the arts increases young adult net migration. Environmental variables, for example, natural amenities and protected federal lands are particularly important in rural settings in attracting young adults. These findings suggest that policy makers interested in attracting and retaining young adults should pay closer attention to social and environmental factors and consider creating more opportunities for arts employment in general. For rural areas, improving the attractiveness of natural amenities and better protection of federal lands is also recommended.

The Impact of Community Social Capital on the occurrence of Injuries in adolescents and falls in older adults: Population-based Studies Conducted in Canadian samples

The objectives of this thesis were to study specific Canadian populations in order to examine; (1) relationships between the neighbourhood-level social capital and injuries in youth, as well as (2) falls in older adults, and; (3) to address methodological issues relevant to the study of such relationships. The thesis is comprised of four manuscripts. The first addresses methodological issues surrounding the validation of neighbourhood-level variables for the study of adolescent health, and demonstrates the existence of structural confounding in the study of related etiological relationships. Informed by the latter, the second manuscript examines the association between neighbourhood-level social capital and injuries in youth, and demonstrates that lower levels of social capital are protective factors for girls but not for boys. Manuscript 3 uses an international database focused on older adults, and shows that our existing measure of social capital is valid at neighbourhood levels, but also that there is a high possibility for the existence of structural confounding among Canadian older adults. The fourth manuscript then examines the association between neighbourhood-level social capital and the occurrence of falls in older adults and determines that differences between neighbourhoods are important factors in the occurrence of falls, and that higher levels of social capital are a risk factor for falls. Taken together, results from this thesis provide a better understanding of the role of neighbourhood-level social capital on the occurrence of injuries in Canadian youth and on the occurrence of falls in older adults. Our contributions were important both methodologically and etiologically.
