Relación de los factores laborales e individuales con la carga mental de los trabajadores de una institución minera (2014)

Objetivo: Establecer la relación de los factores laborales e individuales con la carga mental en los trabajadores del área de contratación y titulación minera y los de seguimiento y control en una institución minera durante el año 2014. Materiales y métodos: Estudio de corte transversal en 298 trabajadores que trabajan en una Institución Minera, en la ciudad de Bogotá. La identificación de los factores laborales e individuales relacionados con la carga mental se hizo mediante la aplicación de un cuestionario autodiligenciado utilizando la guía de Estimación de la carga mental de trabajo: método NASA TLX, en el cual se realizó análisis de medidas de tendencia central y se indagó relación a través de la prueba Chi cuadrado de Pearson, usando nivel de significación del 5%, con el programa SPSS 20. Resultados: La población predominante era de género masculino, donde la mayoría de los trabajadores fueron ingenieros pertenecientes al área de seguimiento y control, se evidenció asociación estadísticamente significativa entre la profesión con la percepción de exigencia física (p ≤ 0,001), de igual modo entre área de trabajo con la percepción de exigencia mental (p ≤ 0,001), en la cual se establece que la carga mental y el factor profesional (técnicos) y el factor laboral (área de seguimiento y control), son determinantes para la aparición de fatiga fisiológica y cognitiva, ya que en estos se evidencia mayor exigencia física en los trabajadores técnicos con un 81,40% y en los trabajadores del área de seguimiento y control con un 99,04%. Conclusión: Se encontró una alta exigencia mental, temporal y esfuerzo en los trabajadores y una relación significativa entre la profesión con la percepción de exigencia física, predominando en los técnicos, seguidos de abogados e ingenieros y entre el área de trabajo con la percepción de exigencia mental, siendo mayor en el área de seguimiento y control.

Mental rotation in Williams syndrome: an impaired ability

Typically developing young children and individuals with intellectual disabilities often perform poorly on mental rotation tasks when the stimulus they are rotating lacks a salient component. However. performance can he improved when salience is increased. The present study investigated the effect of salience oil mental rotation performance by individuals with Williams syndrome. Individuals with Williams syndrome and matched controls were presented with two versions of a mental rotation task: a no salient component condition and a salient component condition. The results showed that component salience did not benefit individuals with Williams syndrome in the same manner as it did controls.

The Effect of Mental Health Problems on Children’s Ability to Discriminate Amongst Thoughts, Feelings and Behaviours

Many young children appear to have skills sufficient to engage in basic elements of cognitive behaviour therapy (CBT). Previous research has, however, typically used children from non-clinical populations. It is important to assess children with mental health problems on cognitive skills relevant to CBT and to compare their performance to children who are not identified as having mental health difficulties. In this study 193 6 and 7 year old children were assessed using a thought–feeling–behaviour discrimination task [Quakley et al. Behav. Res. Therapy 42 (2004) 343] and a brief IQ test (the WASI). Children were assigned to groups (at risk, borderline, low risk) according to ratings of their mental health made by their teachers and parents on the Strengths and Difficulties Questionnaire [Goodman, J. Am. Acad. Child Adolescent Psych. 40 (2001) 1337]. After controlling for IQ, children ‘at risk’ of mental health problems performed significantly less well than children with a ‘low risk’ of mental health problems. Before receiving CBT, children’s meta-cognitive development should be assessed and additional help provided to those with meta-cognitive difficulties.

Verbal short‐term memory performance in pupils with Down Syndrome

Research has shown that verbal short‐term memory span is shorter in individuals with Down syndrome than in typically developing individuals of equivalent mental age, but little attention has been given to variations within or across groups. Differences in the environment and in particular educational experiences may play a part in the relative ease or difficulty with which children remember verbal material. This article explores the performance of 26 Egyptian pupils with Down syndrome and 26 Egyptian typically developing children on two verbal short‐term memory tests: digit recall and non‐word repetition tasks. The findings of the study revealed that typically developing children showed superior performance on these tasks to that of pupils with Down syndrome, whose performance was both lower and revealed a narrower range of attainment. Comparisons with the performance of children with Down syndrome in this study suggested that not only did the children with Down syndrome perform more poorly than the typically developing children, their profile also appeared worse than the results of studies of children with a similar mental age with Down syndrome carried out in western countries. The results from this study suggested that, while deficits in verbal short‐term memory in Down syndrome may well be universal, it is important to recognise that performances may vary as a consequence of culture and educational experiences. The significance of these findings is explored with reference to approaches to education and how these are conceptualised in relation to children with disabilities.

Reviewing the learning organisation model in a child and adolescent mental health service

From 1995 onwards, a child and adolescent mental health service (CAMHS) applied Senge's learning organisation model. This review compared service performance with that of peer services 5 years later and explored whether any differences were associated with the application of this model. The comparison methodology used quantitative analysis of external data from the Department of Human Services, together with qualitative analysis of material including interviews with CAMHS directors and service managers. Results showed high evaluation activity and high quality, efficiency and efficacy of care compared with other services. Several restraints to the optimal application of the model were identified, including inadequate training of new managers, service overload, major external organisational change and limited investment in information systems. Other outcomes are discussed.

Leaders and their teams : learning to improve performance with emotional intelligence and using choice theory

Looks at the relationship between emotional intelligence and choice theory in the work world, with particular emphasis on the implications on health and productivity. Most of us have a managing or leading role of some sort, whether at home, in community life, or at work. Also, as a professional, one can be leading through professional expertise and not necessarily because of one's place in the organizational hierarchy. There is an increasing awareness of the role of leadership and team development in organizational development, for example in health care where change is needed to manage the chronic disease burden (Dunbar et al., 2007) and utilizing and retaining a dwindling workforce (Schoo, Stagnitti, Mercer, & Dunbar, 2005). This is forcing leaders and their teams to work as smart as they can with resources that are available to them. Positive leadership has been associated with outcomes that include happy relationships, teamwork, learning, recognition, staff retention, and health and wellbeing. There is evidence that emotionally intelligent leaders in workplaces are able to bring about these positive out- comes because they are attuned to the emotions that move people around them (Goleman, Boyatzis, & McKee, 2002). In this sense, emotion can be defined as aroused energy that takes a direction (Hunt, 2004a) (Latin: e = from, movere = to move). Valerie Hunt regards emotion as the metronome of life (Hunt, 2004b). Although emotion can be a feeling state (e.g., fear, anger, joy, hate or sorrow) associated with action, its energy is, according to Hunt, directed to action, to behave(Hunt, 2004b). As mentioned in an earlier publication (Schoo, 2005), Pert (Flowers, Grubin, & Meryman-Brunner, 1993) regards emotions as a bridge that connects the mental and physical realities (p.187), and sees neuropeptides as the physical representations of these emotions. Negative thoughts and emotions such as excitement and anger have been found to increase gut motility, cancer risk and arterial plaque formation which can lead to a heart infarct (Pert, 1997), whereas positive emotions seem to do the opposite.

An examination of the consistency of investigative interviewers' performance

Three original studies were conducted to examine the consistency of investigative-interviewer performance across similar and distinct interview tasks. Overall, the degree of consistency depended on numerous factors, including the nature of the event and interview paradigm, the precision of the assessment measure and whether group versus individual stability was measured. The portfolio highlights and discusses some of the complexities that can arise when conducting a parenting capacity assessment with a patient who has, or is suspected of having, an intellectual disability. Four case studies are presented.

Elite athletes' perceptions of the effects of illicit drugs use on athletic performance

Objective: To investigate the perceived risks and benefits that elite athletes associate with illicit drugs and their beliefs concerning the effects of recreational drug use on athletic performance.

Design: Self-administered survey.

Participants: Nine hundred seventy-four elite athletes (mean age, 23 years; range, 18-30 years) were recruited from 8 national sporting organizations in Australia and the Australian Institute of Sport.

Interventions: Participants completed a self-administered survey that included questions exploring participants’ perceptions regarding the effects of illicit drug use on physical performance.

Setting: National sporting organization meetings or competitions.

Main Outcome Measures: The main outcome measure was risk perception on athletic performance associated with illicit drug use.

Results: The majority of athletes believed that illicit drug use would impact negatively on athletic performance. The main perceived effects of illicit drugs on athletic performance were physical and mental functioning. A minority of athletes indicated that drug use would not impact on physical performance when taken during the offseason or in moderation.

Conclusions: The main risks perceived in association with illicit drug use were short-term consequences, such as physical and mental functioning, rather than long-term health consequences. The current findings may contribute to the development of harm reduction strategies that communicate drug-related consequences to elite athletes in an appropriate and effective manner.

How important is team structure to team performance?

This paper discusses the effects of team structure on the performance of design teams. Three types of team structures are differentiated on the basis of the functional and social groups that result from task dependencies and interaction opportunities. The reported findings are based upon results from simulation-based studies using a computational model. Differences across the team structures are investigated through a series of simulations in which the team membership and the workload busyness of the team members are independent variables, and the team performance and formation of team mental models are the dependent variables. Team performance is measured in terms of the ability of the team members to coordinate the set of tasks the team needs to perform. Findings suggest that, in general, flat teams facilitate formation of team mental models, while functional teams are best for efficient task coordination.

Better access to mental health : mapping the evidence supporting participation in meaningful occupations

Introduction: The purpose of this scoping and mapping project is to assess evidence for the use of focused psychological strategies (FPS) under the Better Access to Mental Health (BAMH) scheme to enable people with mental health problems to increase their functional performance and to participate in meaningful occupations. In particular, it aims to provide an accessible summary of evidence for practitioners who use FPS with their clients.

Methods: Evidence scoping and mapping is a relatively new technique, used to provide an overview of key findings in an area of practice. A five stage process of scoping and mapping was used in this project.

Results: A total of 81 studies which addressed the use of focused psychological strategies to promote functional performance and participation in meaningful occupations were found. Surprisingly, only three were published in occupational therapy journals with one further article being authored by occupational therapists. Three maps are provided showing this evidence by diagnosis, intervention and level of evidence.

Conclusion: Clinicians can say with some confidence that cognitive behavioural therapies are effective functional tools, particularly when working with people with depression or schizophrenia. They can also be confident that good quality evidence exists across a range of diagnoses, although there are many gaps where little to no research has been conducted. Suggestions for further research are provided which take into account the findings of these maps.

Computational studies to understand the role of social learning in team familiarity and its effects on team performance

This paper concerns social learning modes and their effects on team performance. Social learning, such as by observing others' actions and their outcomes, allows members of a team to learn what other members know. Knowing what other members know can reduce task communication and co-ordination overhead, which helps the team to perform faster since members can devote their attention to their tasks. This paper describes agent-based simulation studies using a computational model that implements different social learning modes as parameters that can be controlled in the simulations. The results show that social learning from both direct and indirect observations positively contributes to learning about what others know, but the value of social learning is sensitive to prior familiarity such that minimum thresholds of team familiarity are needed to realise the benefits of social learning. This threshold increases with task complexity. These findings clarify the level of influence that sociality has on social learning and sets up a formal framework by which to conduct studies on how social context influences learning and group performance.

An evaluation of the Shanghai mental health service schizophrenia rehabilitation program

This study aimed to evaluate the effectiveness of a rehabilitation program for people with schizophrenia in Shanghai, China. Thirty-five people with schizophrenia participated in an eight-module program that focused on a range of psychosocial skills, while 38 others received treatment as usual in the community. Participants were assessed at baseline and subsequently at 4-week intervals over 12 weeks using the Positive and Negative Syndrome Scale, Clinical Global Impression Scale, Drug Attitude Inventory, and Personal and Social Performance Scale. The rehabilitation program participants demonstrated significantly better improvement over the course of the program than did the control participants on all measures. The rehabilitation program is effective in addressing psychosocial deficits evident in many people who have schizophrenia, and it should be implemented more widely.

Examination of the effect of mental reinstatement of context acress developmental level, retention interval and type of mnemonic instruction

The effect of mental reinstatement of context was examined using a 4*5*2 factorial design incorporating four age groups (6-year-olds, 8-year-olds, 11-year-olds and adults), two retention intervals (1 day and 2 weeks after the stimulus event) and five interview conditions. The interview conditions included; free recall, mental reinstatement-environment (where the setting was reinstated but no event-related detail was provided in the mnemonic instruction), mental reinstatement-event (where specific event-related content was provided), mental reinstatement-combined (a combination of the two above-mentioned methods) and specific questions. Overall, mental reinstatement (irrespective of the type) was found to enhance correct recall performance compared to free recall and (unlike specific questions) it did not lead to greater number of commission errors. Contrary to our initial predictions, however, there was no evidence of any special benefit of mental reinstatement for children and the effect of the technique did not vary consistently as a function of retention interval.

Does extensive free narrative prompting minimise the effect of mental reinstatement on children's recall of events?

The effect of mental reinstatement on children's recall is unclear. One factor that may impact its effectiveness is the degree to which interviewers prompt children during an interview. We examined whether interviewers’ degree of narrative prompting moderated the effect of mental context reinstatement during children's recall of a staged event. Younger and older children were interviewed 7–10 days after the event. Half were told to mentally reinstate the context and half were not. In a fully crossed design, half also received extended narrative prompting during the interview and half did not. We predicted that extensive narrative prompting should reduce any observable benefit of mental reinstatement, especially for older children. However, mental reinstatement had no beneficial effect on recall performance. It is possible that methodological differences, low statistical power, and a small effect size may have reduced the observable benefit of mental reinstatement in comparison to other studies. Overall, the findings of this study suggest that until further research can clearly define the parameters in which mental reinstatement is useful, and therefore produce findings with greater consistency across studies, there is little support for its use in investigative interviews with child witnesses.
