Aplicación del ISRA-J en Adolescentes

La presente investigación trata de exponer los resultados de la aplicación de la versión para adolescentes del ISRA, un instrumento de evaluación multidimensional de la ansiedad, a una muestra de jóvenes españoles. Al igual que la versión para adultos del ISRA, el ISRA-J Adolescentes presenta diferentes situaciones ante las cuales se pueden dar tres tipos de respuestas de ansiedad: cognitiva, fisiológica y motora. El objectivo principal de este trabajo consiste en el estudiar las características psicométricas del ISRA-J. Esta investigación ha sido llevada a cabo utilizando una muestra de sujetos normales, de edad comprendida entre 12 y 18 años, de ambo sexos, en varios institutos dela Comunidad de Madrid. Serán presentados y comentados los hallazgos y los datos obtenidos en lo que atañe a las propiedades de validez (análises factorial y validez concurrente con el STAI de Spielberger) así como las diferencias de edad y de sexo detectadas mediante la análisis de la varianza.

A multimédia utilizada em psicologia experimental e as limitações do equipamento informático

A Psicologia Experimental pode obter imensos proveitos da utilização da multimédia: uma maior regularidade na apresentação de estímulos ao sujeito, uma maior diversidade na qualidade dos estímulos a apresentar, uma maior precisão na medição dos tempos de resposta. No entanto, o equipamento informático, apesar de se encontrar em evolução crescente constante, apresenta algumas limitações, nomeadamente, ao nível dos periféricos de interface com o utilizador. O ecrã não é, por omissão, rigoroso na apresentação de estímulos visuais temporizados. O teclado introduz desvios na medição dos tempo de resposta. Este artigo discute formas de obviar estes e outros problemas, de forma a que a Psicologia Experimental possa obter os melhores benefícios da conjugação das suas necessidades com as potencialidades da Multimédia.

Psicologia das motivações ajurídicas do sentenciar : a emergência do saber em detrimento do poder

RESUMO:A pretensão deste trabalho reside na indagação sobre a eventual existência de um acervo de motivações ajurídicas que fundamentem as decisões judicias, erigindo como actor principal o Aplicador da Lei. Para tanto – recorreu-se à utilização de um instrumento construído pela autora, em 2005 – a Grelha de Observação das Motivações Ajurídicas do Sentenciar – destinado a captar aspectos considerados principais na comunicação dos protagonistas do processo de criminalização secundária, quer ao nível da comunicação verbal (C.V.) quer no concerne à comunicação não verbal (C.N.V.), verificando, depois, em presença das decisões, as razões justificativas evidenciadas. E que constituíram o suporte ajurídico de cada sentença. Assim, realizou-se um trabalho de observação, tendo a Grelha de Observação sido aplicada por licenciados em Psicologia, estudantes do 2º ciclo de Psicologia Forense e da Exclusão Social (Universidade Lusófona de Humanidades e Tecnologias), e alunos da Faculdade de Direito (Universidade Nova de Lisboa), que operaram em três tribunais criminais de Lisboa A amostra é constituída por 25 julgamentos, com um total de 64 personagens judiciais. Os resultados, ainda que meramente indicativos, demonstram uma tendência para a validade e consistência interna da grelha, indiciando também a verificação de motivações ajurídicas nas decisões judiciais. ABSTRACT: The intention of this work resides in the investigation of the eventual existence of an amount of non judicial motivations which support judicial decisions, where the law applicator arises as the main actor. For such - the use of an instrument built by the author in 2005 was resorted to - the Observation grid of the non judicial motivations of the sentencing - destined to capture aspects considered primary in the communication of the key players of the secondary criminalization process, in both the verbal communication level and in what concerns non verbal communication, later verifying, in the presence of the decisions, the evidenced justifiable reasons, which established the non judicial support of each sentence. Thus, an observational work was performed, having been applied the observation grid by Psychology graduates, students of the masters in Forensic Psychology and of Social Exclusion (Lusófona University of Humanities and Technology), as well as students of the Faculty of Law (New University of Lisbon), which operated in three criminal courts in Lisbon. The sample consists of 25 trials, with a total of 64 judicial characters. The results, even if only indicative, show a trend towards internal consistency and validity of the grid, also indicating the verification of non judicial motivations in judicial decisions.

Desesperança e agressividade na adolescência e qualidade de vinculação aos pais

RESUMO: As relações que constituímos com aqueles que de mais perto nos rodeiam são uma das partes, senão a parte mais relevante da nossa vida (Canavarro, 1999). Assim, a teoria da vinculação coloca grande ênfase na natureza da relação de vinculação (Bowlby, 1979). No primeiro capítulo é elucidado o modelo de desenvolvimento da vinculação de Bowlby (1969/1982; 1988) e de Ainsworth e colaboradores (1978). No segundo capítulo são explicadas as mudanças que ocorrem na fase da adolescência. No terceiro capítulo, é destacado o padrão comportamental agressivo do adolescente, o qual se pode traduzir numa vinculação insegura (Almeida, 2000). Estas situações podem levar o sujeito a apresentar comportamentos de desesperança, conceito este que irá ser desenvolvido no quarto capítulo. Sendo o principal objectivo da investigação estudar em que medida a qualidade de vinculação aos pais e a estrutura familiar estão relacionadas com a desesperança e a agressividade nos adolescentes, conclui-se que o adolescente com uma história de vinculação insegura apresenta menos confiança, maior alienação e, consequentemente, maior desamparo e desesperança (Bowlby, 1969/1982, 1973; Bretherton & Waters, 1985). Relativamente à estrutura familiar, o estudo reporta que a coesão e a adaptabilidade estão correlacionadas positivamente com a confiança e negativamente com a alienação. ABSTRACT: The relationships that we form of those who surround us are closer to one party, if not the most important part of our lives (Canavarro, 1999). Thus, attachment theory places great emphasis on the nature of the attachment relationship (Bowlby, 1979). In the first chapter, is elucidated development model of the binding of Bowlby (1969/1982, 1988) and Ainsworth and colleagues (1978). The second chapter explains the changes that occur during adolescence. The third chapter is highlighted the behavioral patterns of aggressive adolescents, which may result in insecure attachment (Almeida, 2000). These situations can cause the subject to present behavior of hopelessness, that this concept will be developed in the fourth chapter. Since the main aim of the research study to what extent the quality of attachment to parents and family structure are related to hopelessness and aggression in teenagers, it is concluded that the adolescent with a history of insecure attachment have less trust, increased alienation and, consequently, greater helplessness and hopelessness (Bowlby, 1969/1982, 1973, Bretherton & Waters, 1985). With regard to family structure, the study reports that the cohesion and adaptability are positively correlated with the confidence and negatively with alienation.

Psicologia das motivações ajurídicas do sentenciar : o lado invisivel da decisão

RESUMO: A presente investigação erige como objective inicial predizer as potencialidades/qualidades avaliativas da Grelha de Observação (Louro, 2005), realçando os diferentes comportamentos, a nível verbal e não-verbal, presentes em tribunal, relativamente aos arguidos, vítimas, testemunhas e juízes, num conjunto 34 julgamentos presenciados, no tribunal da Boa-Hora, 4ª Vara Criminal. Nesta medida, foram preenchidas 249 grelhas em contexto judicial, 190 do sexo feminino e 59 do sexo masculino, das quais, 43 grelhas referiam-se a arguidos dispostos 34 julgamentos, devido ao facto de haver julgamentos com mais do que um arguido; 14 a vítimas, dado a maior parte dos julgamentos a vítima fazer-se representar pelo Ministério Público; 108 a testemunhas e 73 grelhas aplicadas a 4 juízes presidentes de cada colectivo. Verificaram-se diferenças estatisticamente significativas no que toca aos comportamentos verbal e não verbal apresentados pelas personagens judiciais. Os resultados foram apoiados e discutidos com base na literatura revista. ABSTRACT: The present investigation aims at predicting the evaluative potential/quality of the Grelha de Observação (Louro, 2005), highlighting the different behaviors (verbal and non-verbal) displayed in a court of law, regarding the arguidos, victims, witnesses and judges, in a set of 34 observed trials at the court of Boa-Hora, “4rd” Vara Criminal. Therefore, 249 grills were filled in judicial contxt, 190 females and 59 males, from which, 43 grills were arguidos from the 34 trials (in some trials, there were more than one arguido); 14 regarding victims, since most trials she is represented by the public prosecution service; 108 witnesses and 73 grills were applied to 4 judges presidents from each collective jury. Statistically significant differences were found for the comparison between judicial characters for verbal and non-verbal behavior. The results were supported and discussed from the revised literature.

Factors affecting nutrition behavior among middle-class adolescents in urban area of Northern region of Brazil

INTRODUCTION: Brazil has been called a nation in nutrition transitional because of recent increases in the prevalence of obesity and related chronic diseases. With overweight conditions already prevalent among middle-income populations, there exists a need to identify factors that influence nutrition behavior within this group. OBJECTIVE: To address this subject, a research study was implemented among middle-class adolescents attending a large private secondary school in Manaus, Amazonas, Brazil. The study determined the availability and accessibility of snack foods as well as subjects’ attitudes and preferences towards, and the influence of family and friends on healthy (high-nutrient density) snack choices. METHODS: The 4-stage process included: (a) a nutrition expert focus group discussion that reported local nutrition problems in general and factors related to adolescent nutrition, (b) an adolescent pilot survey (n=63) that solicited information about snacking preferences and habits as well as resources for nutrition information and snack money; (c) a survey of various area food market sources to determine the availability and accessibility of high nutrient density snacks; and (d) a follow-up adolescent survey (n=55) that measured snack food preferences and perceptions about their cost and availability. RESULTS: Results included the finding that, although affordable high nutrient density snacks were available, preferences for low nutrient density snacks prevailed. The adolescents were reportedly more likely to be influenced by and obtain nutrition information from family members than friends. CONCLUSION: From study results it is apparent that a focus on food availability will not automatically result in proper nutritional practices among adolescents. This fact and the parental influence detected are evidence of a need to involve adolescents and their parents in nutrition education campaigns to improve adolescent snack food choices.

Shiftworking families: parents' working schedule and sleep patterns of adolescents attending school in two shifts

OBJECTIVE: To explore whether parents' engagement in shift work affects the sleep habits of their adolescent children who attend school in two shifts. METHODS: The data were drawn from an extensive survey of sleep and daytime functioning of adolescents attending school one week in the morning and the other in the afternoon. The participants were 1,386 elementary and high school students (11-18 years old) whose parents were both employed. The data were analyzed using MANOVA, with parents' work schedule, adolescents' gender and type of school as between-subject factors. RESULTS: Parents' working schedule significantly affected the sleep patterns of high school adolescents. When attending school in the morning, adolescents whose parents were both day workers woke up somewhat later than adolescents with one shiftworking parent. In addition, they slept longer than adolescents whose parents were both shift workers. On weekends, adolescents whose parents both worked during the day went to bed earlier than adolescents whose parents were both shiftworkers. They also had smaller bedtime delay on weekends with respect to both morning and afternoon shifts than adolescents for whom one or both parents worked shifts. A significant interaction between parents' working schedule, adolescents' gender and type of school was found for sleep extension on weekends after afternoon shift school. CONCLUSIONS: Parental involvement in shift work has negative effects on the sleep of high school adolescents. It contributes to earlier wake-up time and shorter sleep in a week when adolescents attend school in the morning, as well as to greater bedtime irregularity.

Influence of environmental temperature and humidity on the acute ventilatory response to exercise in asthmatic adolescents

Asthma is a chronic inflammatory disorder of the respiratory airways affecting people of all ages, and constitutes a serious public health problem worldwide (6). Such a chronic inflammation is invariably associated with injury and repair of the bronchial epithelium known as remodelling (11). Inflammation, remodelling, and altered neural control of the airways are responsible for both recurrent exacerbations of asthma and increasingly permanent airflow obstruction (11, 29, 34). Excessive airway narrowing is caused by altered smooth muscle behaviour, in close interaction with swelling of the airway walls, parenchyma retractile forces, and enhanced intraluminal secretions (29, 38). All these functional and structural changes are associated with the characteristic symptoms of asthma – cough, chest tightness, and wheezing –and have a significant impact on patients’ daily lives, on their families and also on society (1, 24, 29). Recent epidemiological studies show an increase in the prevalence of asthma, mainly in industrial countries (12, 25, 37). The reasons for this increase may depend on host factors (e.g., genetic disposition) or on environmental factors like air pollution or contact with allergens (6, 22, 29). Physical exercise is probably the most common trigger for brief episodes of symptoms, and is assumed to induce airflow limitations in most asthmatic children and young adults (16, 24, 29, 33). Exercise-induced asthma (EIA) is defined as an intermittent narrowing of the airways, generally associated with respiratory symptoms (chest tightness, cough, wheezing and dyspnoea), occurring after 3 to 10 minutes of vigorous exercise with a maximal severity during 5 to 15 minutes after the end of the exercise (9, 14, 16, 24, 33). The definitive diagnosis of EIA is confirmed by the measurement of pre- and post-exercise expiratory flows documenting either a 15% fall in the forced expiratory volume in 1 second (FEV1), or a ≥15 to 20% fall in peak expiratory flow (PEF) (9, 24, 29). Some types of physical exercise have been associated with the occurrence of bronchial symptoms and asthma (5, 15, 17). For instance, demanding activities such as basketball or soccer could cause more severe attacks than less vigorous ones such as baseball or jogging (33). The mechanisms of exercise-induced airflow limitations seem to be related to changes in the respiratory mucosa induced by hyperventilation (9, 29). The heat loss from the airways during exercise, and possibly its post-exercise rewarming may contribute to the exercise-induced bronchoconstriction (EIB) (27). Additionally, the concomitant dehydration from the respiratory mucosa during exercise leads to an increased interstitial osmolarity, which may also contribute to bronchoconstriction (4, 36). So, the risk of EIB in asthmatically predisposed subjects seems to be higher with greater ventilation rates and the cooler and drier the inspired air is (23). The incidence of EIA in physically demanding coldweather sports like competitive figure skating and ice hockey has been found to occur in up to 30 to 35% of the participants (32). In contrast, swimming is often recommended to asthmatic individuals, because it improves the functionality of respiratory muscles and, moreover, it seems to have a concomitant beneficial effect on the prevalence of asthma exacerbations (14, 26), supporting the idea that the risk of EIB would be smaller in warm and humid environments. This topic, however, remains controversial since the chlorified water of swimming pools has been suspected as a potential trigger factor for some asthmatic patients (7, 8, 20, 21). In fact, the higher asthma incidence observed in industrialised countries has recently been linked to the exposition to chloride (7, 8, 30). Although clinical and epidemiological data suggest an influence of humidity and temperature of the inspired air on the bronchial response of asthmatic subjects during exercise, some of those studies did not accurately control the intensity of the exercise (2, 13), raising speculation of whether the experienced exercise overload was comparable for all subjects. Additionally, most of the studies did not include a control group (2, 10, 19, 39), which may lead to doubts about whether asthma per se has conditioned the observed results. Moreover, since the main targeted age group of these studies has been adults (10, 19, 39), any extrapolation to childhood/adolescence might be questionable regarding the different lung maturation. Considering the higher incidence of asthma in youngsters (30) and the fact that only the works of Amirav and coworkers (2, 3) have focused on this age group, a scarcity of scientific data can be identified. Additionally, since the main environmental trigger factors, i.e., temperature and humidity, were tested separately (10, 28, 39) it would be useful to analyse these two variables simultaneously because of their synergic effect on water and heat loss by the airways (31, 33). It also appears important to estimate the airway responsiveness to exercise within moderate environmental ranges of temperature and humidity, trying to avoid extreme temperatures and humidity conditions used by others (2, 3). So, the aim of this study was to analyse the influence of moderate changes in air temperature and humidity simultaneously on the acute ventilatory response to exercise in asthmatic children. To overcome the above referred to methodological limitations, we used a 15 minute progressive exercise trial on a cycle ergometer at 3 different workload intensities, and we collected data related to heart rate, respiratory quotient, minute ventilation and oxygen uptake in order to ensure that physiological exercise repercussions were the same in both environments. The tests were done in a “normal” climatic environment (in a gymnasium) and in a hot and humid environment (swimming pool); for the latter, direct chloride exposition was avoided.
