¿Influye el liderazgo del entrenador sobre la resiliencia de equipo? Efecto mediador de los conflictos intragrupo y la cohesión grupal / Does coach leadership influence team resilience? Mediating effect of intra-group conflict and group cohesion

Resumen Introducción/objetivo: El presente estudio tiene como objetivo examinar la rela ción entre el liderazgo transformacional del entrenador y las características de resiliencia y la vulnerabilidad bajo presión, así como analizar si los factores del conflicto intragrupo (social y tarea) y de la cohesión grupal (social y tarea), pudieran mediar la relación entre dichas variables. Método: A través de un diseño longitudinal, se incluyó a un total de 301 depor tistas inscritos en los JUDEX, pertenecientes a 34 equipos de fútbol y voleibol, con edades comprendidas entre 13 y 18 años (M = 15.72; DT = 1.33). Resultados: Los resultados mostraron una relación positiva entre el liderazgo transformacional del entrenador y las características de resiliencia, y una asociación negativa respecto a la vulnerabilidad bajo presión. Además, el conflicto intragrupo (social y tarea) actuó como mediador entre la relación del liderazgo trans formacional del entrenador y la resiliencia de equipo. En cuanto al papel mediador de la cohe sión grupal, solo la cohesión tarea actuó como mediadora entre el liderazgo transformacional del entrenador y la resiliencia de equipo. Conclusiones: La presente investigación muestra la importancia del liderazgo del entrenador para mejorar la resiliencia del equipo en categorías de formación, y la influencia positiva que tiene la reducción de los conflictos intragrupo y el aumento de la cohesión tarea durante la temporada.

Abstract Introduction/objective: The present study aimed to examine the relationship be tween transformational coach leadership with the characteristics of resilience and vulnerability under pressure, as well as to analyze whether the factors of intra-group conflict (social and task) and group cohesion (social and task) could mediate the relationship between these variables. Method: Through a longitudinal design, a total of 301 athletes enrolled in the JUDEX, belong ing to 34 soccer and volleyball teams, and aged between 13 and 18 years (M = 15.72; SD = 1.33). Results: The results showed a positive relationship between transformational leadership of the coach and resilience characteristics, and a negative association with respect to vulnerability under pressure. In addition, intra-group conflict (social and task) acted as mediators between the relationship between transformational coach leadership and team resilience. Regarding the mediating role of group cohesion, only task cohesion acted as a mediator between trans formational coach leadership and team resilience. Conclusions: This research draws as main conclusion the importance of the coach's leadership to improve team resilience in youth cate gories, and the positive influence of the reduction of intragroup conflicts and the increase of task cohesion during the season.

Learning and transfer of training: a quasi-experiment with longitudinal design / Aprendizagem e transferência de treinamento: um quase-experimento com desenho longitudinal / Aprendizaje y transferencia de entrenamiento: un casi-experimento con diseño longitudinal

This paper aimed to evaluate learning in three trainings held at a Brazilian federal public organization. It is a longitudinal quasiexperiment with three waves, pre-test (before training ­ T1), post-test 1 (right after the end of the training ­ T2) and post-test 2 (around three months after the training - T3). Learning was assessed with situational tests, so results are based on performance rather than self-assessment. Results show that the experimental group obtained better scores in post-test 1 than it did in the pre-test and better scores than the control group did in post-test 2. There were no difference in the results obtained by the control group, comparing pre and post-test, and that there was no difference in tests according to previous experience and demographic data. Results indicate that learning occurred as a consequence of training and was not explained by other factors of the organizational environment or individuals. (AU)

Esse artigo teve como objetivo mensurar a aprendizagem em três seções de treinamento realizadas em uma organização pública federal brasileira. Trata-se de um quase experimento longitudinal, com três ondas, sendo o pré-teste (antes do treinamento), o pós-teste 1 (imediatamente após o término do treinamento) e o pós-teste 2 (após três meses do término do treinamento). A aprendizagem foi medida usando-se testes situacionais, garantindo que os resultados são baseados em desempenho e não auto relato. Os resultados indicam que o grupo experimental obteve melhores notas no pós-teste 1 do que no pré-teste e melhores notas no pós-teste 2 quando comparado ao pós-teste 1. Não foram encontradas diferenças no grupo controle entre o pré e pós teste, nem diferenças nos resultados dos testes devidas à experiência prévia ou a dados demográficos, indicando que a aprendizagem ocorreu como consequência do treinamento e não de explicações alternativas.

Health Beliefs Predict Self-Care Practices And Glycaemic Control In Malaysian Patients With Insulin-Treated Diabetes: A Longitudinal Study

@#The practice of diabetes self-care plays an important role in achieving and maintaining good glycaemic control. However, not all patients with insulin-treated diabetes engage in their self-care activities. There is some evidence that self-care practices in patients with insulin-treated diabetes can be understood and predicted by their health beliefs, although studies are often hampered by methodological weaknesses, and the fact that less is known about adults with insulin-treated diabetes in Malaysia. This study was conducted to examine whether health beliefs (as specified in the Health Belief Model: HBM) can predict self-care practices and glycaemic control in patients with insulin-treated diabetes in Malaysia. Longitudinal design with self-reported questionnaire measures was administered at baseline (Time 1:T1) and six months later (Time 2: T2). Participants were recruited from three endocrinology clinics in Malaysia. The measures included self-care practices (diet, insulin intake, exercise and self-blood glucose monitoring: SMBG), health beliefs and diabetes knowledge. Participants’ glycaemic control was examined based on their glycated hemoglobin (HbA1c) results. Data analysis was performed at different points of the study times; T1, T1-T2 and T2. Diabetes knowledge and demographic data were controlled for in predictive statistical analyses. A total of 159 patients with insulin-treated diabetes (aged 18-40 years) completed the measures at T1. Of these, only 108 (67.9%) completed follow-up measures at T2. However, demographic characteristics were not significantly different between those who completed and dropped out of the study (p>0.05). The HBM was significantly predictive of diet self-care at T2, insulin intake practice at T1 and HbA1c at T1-T2 andT2. Of the HBM constructs, perceived benefits significantly predicted good dietary habits at T1 (OR 1.92) and T2 (OR .23) and adherence to insulin injection at T1 (OR 3.17) and T1-T2 (OR 2.68). With the exception of perceived severity, all other HBM constructs significantly predicted HbA1c [perceived susceptibility (β .169) at T1, perceived barriers (β -.206) and perceived benefits (β -.397) at T2 and cues to action (β -.233) at T1-T2]. Health beliefs predict self-care practices and glycaemic control in young to middle-aged adults with insulin-treated diabetes in Malaysia. Diabetes educators could use this knowledge in their efforts to improve diabetes self-care in this patient groupby modifying those beliefs through their diabetes education.

Analyzing challenges associated with the adoption of longitudinal studies in Work and Organizational Psychology / Analisando desafios associados à adoção de pesquisas longitudinais em Psicologia Organizacional e do Trabalho / Analizando desafíos asociados a la adopción de investigaciones longitudinales en Psicología Organizacional y del Trabajo

This article aims to analyze the main theoretical and methodological challenges associated with the use of longitudinal research designs in Work and Organizational Psychology. Longitudinal designs with three or more points of measurement are rare in the literature. Critical points to be observed include: definition of the interval between first and last measurement of variables, time needed for the effect of an intervention to become observable, quantity of measurements over time, time period between measurements, management of participant drop outs, and analysis of alternative explanations for the effects of interventions or programs. The technical recommendations offered include the use of designs with multiple measurements of independent and dependent variables, such as external variables that threaten the internal and external validity of study conclusions.

Este artigo objetiva analisar os principais desafios teóricos e metodológicos associados ao uso de delineamentos longitudinais de pesquisa em Psicologia Organizacional e do Trabalho. Delineamentos longitudinais com três ondas de mensuração ou mais são raros na literatura da área. Entre os pontos críticos a serem observados está a definição do intervalo de tempo entre a primeira e última mensuração das variáveis, o tempo necessário para que o efeito de uma intervenção se torne observável, a quantidade de mensuração ao longo do tempo, o tempo entre mensurações, o manejo da perda seletiva de sujeitos e a análise de explicações alternativas aos efeitos de intervenções ou programas. Entre as recomendações técnicas estão o uso de delineamentos com múltiplas mensurações, tanto das variáveis independentes e consequentes, como de variáveis externas que ameaçam a validade interna e externa das conclusões desses estudos.

Efectos diferidos y concurrentes del clima de grupo sobre los cambios en el aprendizaje de equipo: el rol modulador de la presión temporal y la sobrecarga de trabajo / Concurrent and Lagged Effects of Team Climate on Team Learning Changes: The Moderator Role of Time Pressure and Work Overload

Los grupos de trabajo son centrales en las organizaciones actuales, y uno de los procesos más relevantes es el aprendizaje de equipo, su desarrollo y sus antecedentes. El presente estudio tiene dos objetivos principales: 1) analizar el efecto del clima del grupo sobre el desarrollo del aprendizaje de equipo y 2) estudiar el rol modulador de diferentes estresores de equipo (sobrecarga y presión temporal) en dicha relación. Los resultados muestran que el clima del equipo influye de manera concurrente y diferida sobre el aprendizaje. La sobrecarga de trabajo modula la relación entre el apoyo a la innovación y el aprendizaje de equipo al inicio del trabajo en grupo. Sin embargo, la presión temporal no parece tener efectos en dicha relación.

Teams are central work units in organizations. One of the processes that are receiving attention is team learning. The focus is on those processes that can predict team learning and its evolution over time. This study has two objectives. First, analyze team climate effect on team learning development. Second, test the moderator role of team stressors (work overload and time pressure) in the relationship between tem climate and team learning. Results obtained shows that team climate have concurrent and differed effects on team learning. On the other hand, work overload moderates the relationship between support for innovation and team learning at the beginning of teamwork, but time pressure does not have effects in the relationship between team climate and team learning.

Growing up with the families of β-thalassaemia major using an accelerated longitudinal design.

Background & objectives: It is difficult for a single investigator to study the psychosocial changes that occur over the life span of an individual affected with a chronic illness like β-thalassaemia major. Therefore, a developmental epidemiological perspective is required to understand the chain of events and problems of psychological nature. We aimed to construct the picture of developmental epidemiology for psychosocial aspects in families of β-thalassaemia major patients attending a tertiary care hospital in north India. Methods: The accelerated longitudinal design was used. The sample consisted of 100 children with β-thalassaemia and their 150 parents, both groups were subdivided further so that each group represented the continuum of longitudinal course. The sampling was done for a period of 16 months from January 2004 to April 2005. Results: Overall 54 per cent of children had significant psychopathology. Within the parents groups, 10 per cent had adjustment disorder, 33.3 per cent depressive disorder, and 10 per cent had anxiety disorder and 11 per cent somatoform disorder; 95 per cent of the parents of newly diagnosed children expressed feeling of dazed and shock, fear of death, hopelessness, separation anxiety and problems with their memory and concentration. There was significant difference only in the domain of psychological health in all the three groups of parents with respect to the quality of life. Among children, quality of life improved with their progression of illness. Growing up with β-thalassaemic family was analyzed. Interpretation & conclusions: The developmental epidemiological perspective was constructed in β -thalassaemic children and their family using an accelerated longitudinal design. Such a design can test the hypothesized aetiological or developmental function of a targeted risk factor within a developmental path and may be used in studying the psychological impact of even other chronic illnesses over the life span of an individual for conceptual and holistic understanding.

Relación entre los niveles de trp's, las medidas de recordación, preferencia de marca y la conducta de compra en consumidores colombianos / Relation between the TRP'S levels, the measure of brand awareness and buying behavior in Colombian consumers

El propósito de la investigación es determinar las relaciones existentes entre los niveles de Target Rating Point (TRP'S) entendidos como el índice acumulado de rating de Televisión mensual frente a los niveles de notoriedad (conocimiento de marca y publicitario), preferencia (favoritismo) y comportamiento (compra y próxima compra), a fin de identificar las principales tendencias derivadas de dichas asociaciones en una categoría de consumo masivo. Para esto, se tomaron los niveles de TRP'S en Televisión, como variable predictora central, así como las medidas de notoriedad de marca (top of mind, espontánea y ayudada), las medidas de notoriedad publicitaria (top of mind, espontánea y ayudada), las medidas de preferencia (marca favorita) y las variables de compra (marca comprada en el último mes y próxima marca a comprar) clasificadas en el conjunto de las variables criterio. El diseño de este estudio es de corte longitudinal de tendencia con K muestras, la muestra general del estudio comprende un conjunto de 4.104 registros agregados derivados de la replicación de 58 muestras mensuales de 500 participantes de ambos géneros con edades entre los 12 y 60 años pertenecientes a los estratos 2 al 6 dentro del período comprendido entre enero de 2004 y octubre de 2008. Los principales hallazgos resaltan el establecimiento de asociaciones estadísticamente significativas entre los niveles de TRP'S (bajo-medio y alto) y el comportamiento diferencial de cada una de las 3 marcas evaluadas dentro de la categoría en relación con sus niveles de notoriedad, preferencia y compra.

The purpose of this research is to determine the existing relation between the Target Rating Point (TRP's) levels understood as the monthly cumulative index Television rating against the levels of visibility (brand and advertising knowledge), preference (favoritism) and behavior (buy and next buy), to identify main trends derived from these associations in a mass consumption category. With this aim TRP's levels in Television were taken as a central predictor variable as well as the brand visibility measurements (top of mind, spontaneous and assisted), preference measurements (favorite brand) and the buying variables (brand bought in the last month and next brand to be bought) classified in the set of criterion variables. The design of this study is longitudinal in trend with K samples; the general sampling of the study includes a set of 4,104 added records derived from the replication of 58 monthly samples of 500 both male and female participants with ages between 12 and 60 years from strata 2 to 6 within a period between January 2004 and October 2008. Main findings enhance the establishment of associations statistically significant among the TRP's levels (low - medium and high) and the differential behavior of each of the 3 brands assessed within the category in relation with their visibility, preference and buying levels.
