Jovens e a internet: Uma relação com a perturbação do sono e o bem-estar psicológico
Dissertação de Mestrado apresentada ao ISPA – Instituto Universitário para obtenção de grau de Mestre em Psicologia na especialidade de SaúdeDissertação de mestrado apresentada ao ISPA – Instituto UniversitárioA internet tornou-se uma ferramenta
essencial para a sociedade, nomeadamente entre os adolescentes. Contudo, cada vez mais se fala do uso
problemático da internet (UPI). Um uso que acarreta diversos riscos a nível funcional e relacional para o
indivíduo. O presente estudo teve como objectivo analisar a relação entre o UPI, a perturbação do sono e o
bem-estar psicológico. Participaram na investigação 2087 adolescentes Portugueses (1040 feminino e 1025
masculino), com idades compreendidas entre os 11 e os 21 anos (M=14.40; DP= 1.96), maioritariamente
alunos do ensino básico, que preencheram via online o questionário sócio-demográfico e de acesso à internet
(Patrão, 2013); a Generalized Problematic Internet Use Scale (GPIUS-2; Caplan, 2010); a Athens Insomnia
Scale (AIS; Soldatos, Dikeos & Paparrigopoulos, 2000) e a versão de 30 itens da Escala de Bem-Estar
Psicológico adaptada para adolescentes portugueses (EBEP-30; Fernandes, 2007). Os resultados demonstram
haver uma relação positiva com a perturbação do sono (rs= 0.247; p= 0.000) e negativa com o bem-estar
psicológico (rs= -0.066; p= 0.003), assim como a perturbação do sono ser um predictor significativo do UPI
(β=0.253; t(2062) = 11.846; p= 0.000). Concluiu-se também haver uma relação significativa com certos
factores sócio-demográficos e de acesso e uso da internet (meio de residência; retenção; prática de
actividade física; idade de início do uso da internet e horas passadas online). Concluiu-se a necessidade de
existência de programas de promoção de comportamentos saudáveis online junto dos adolescentes e de
discussão da problemática junto dos encarregados de educação e professoresThe internet has become an
essential tool for society, specially for teenagers. However, the Problematic Internet Use (PIU) is being

increasingly discussed. An usage which carries various risks on a functional and relational level for the
individual. The present investigation aimed to study the relation between the PIU, sleep disorder and
psychological well-being. The participants in the investigation were 2087 Portuguese teenagers, ages between
11 and 21 years old (M=14.40; SD=1.96), mostly middleschool students who filled in, via online, the
sociodemographic and internet access survey (Patrão, 2013); the Generalized Problematic Internet Use Scale
(GPIUS-2; Caplan, 2010); the Athens Insomnia Scale (AIS; Soldatos, Dikeos & Paparrigopoulos, 2000) and
the 30 item version of Psychological Well-Being Scale adapted for portuguese adolescents (EBEP-30;
Fernandes, 2007). Results show a positive relation with sleep disorder (rs= 0.247; p= 0.000) and a negative
one with psychological well-being (rs= -0.066; p= 0.003), as well as showing how sleep disorder is a
significant PIU predictor (β=0.253; t(2062) = 11.846; p= 0.000). It has also been concluded that there is a
significant relation with certain sociodemographic and Internet access and use factors (area of residence;
exercise practice; first contact with internet; time spent online). The impact of these results alert for the
importance of programmes to promote healthy behaviours online among teenagers and the discussion of this
issue with educators and parents.

Jovens e internet: relação com o bem-estar psicológico, Isolamento social e funcionamento familiar.
Hoje em dia a internet é uma ferramenta que faz parte da rotina diária dos indivíduos,
principalmente dos mais jovens, por questões académicas ou de socialização. Sabe-se que o uso
problemático da internet (UPI) pode afectar vários campos da vida do indivíduo (e.g. relações
sociais; contexto familiar). O isolamento é um indicador de interferências no bem-estar do
indivíduo e os jovens que percepcionam pouco suporte social tanto na escola com o seu grupo de
pares, como no sistema familiar apresentam uma maior predisposição para o desenvolvimento do
UPI. O objectivo geral da investigação foi analisar a relação entre o UPI, isolamento social,
funcionamento familiar e bem-estar psicológico em jovens do ensino básico, secundário e
universitário. Para o efeito utilizou-se um questionário de dados sociodemográficos (Patrão, 2014),
um questionário de acesso e uso da internet, a Generalized Problematic Internet Use Scale
(GPIUS2 - Caplan, 2010), a Psychological Well-Being Scale (PWBS - Fernandes, Vasconcelos-
Raposo & Teixeira, 2010), a Family Assesment Device (FAD – Epstein, Baldwin & Bishop, 1983)
e a UCLA Loliness Scale (Russell, 1996).
Os resultados de uma amostra de 1452 jovens portugueses do ensino básico, secundário e
universitário (M=15.12; DP=4.035) indicam a relação entre a UPI, o isolamento social e o
funcionamento familiar. Existe, por isso, a necessidade de uma intervenção conjunta com todos os
atores (i.e. família, escola e jovens) de forma a delimitar-se estratégias adequadas para a promoção
do uso seguro e saudável da internet no contexto escolar e familiar.info:eu-repo/semantics/publishedVersio
Caracterização da resina ureia-formaldeído modificada com celulose microfibrilada (MFC).
Com a modernização e a alta demanda de madeira, as indústrias desenvolveram técnicas de fragmentação e reconstituição dessa matéria-prima, produzindo desta forma os painéis de madeira. Os painéis de madeira reconstituída podem ser empregados para diferentes usos, dependendo da sua constituição (partículas, fibras ou lâminas) e do adesivo que é utilizado para sua produção, podendo ser natural ou sintético. Pela necessidade de melhoramento das propriedades dos adesivos, diversos pesquisadores como BOSCHETTI (2017) e FERREIRA (2017) buscam alternativas com a incorporação de outros materiais na resina. Desta maneira, a presente pesquisa tem por objetivo caracterizar as propriedades físico-químicas do adesivo comercial ureia-formaldeído e sua modificação com a celulose microfibrilada (MFC) nas proporções de 0,5%, 1,0% e 1,5%
Problematic internet use and feelings of loneliness
Objectives: Internet addiction or problematic internet use (PIU) has been related to feelings of loneliness and social networking. Research suggests that online communication may cause loneliness. We examined if the association between PIU and loneliness is independent of lack of social support, as indicated by lack of a committed romantic relationship, poor family functioning, and lack of time to interact face-to-face due to time online. Methods: Portuguese adolescents and young adults (N = 548: 16-26 years) completed the Generalized Problematic Internet Use Scale-2, the UCLA Loneliness Scale, and the general functioning subscale of the McMaster Family Assessment Device. They also reported if they had a committed romantic relationship, and if being online did not leave them time to be with partner, spend with family and socialise face-to-face with friends. Results: Social networking was reported as among the main preferences by 90.6% of the females and 88.6% of the males. Perceived loneliness was associated with PIU independently of age and indicators of social support. Conclusions: Evolution created neurophysiological mechanisms to recognize satisfying social relationships based on sensory information and bodily feedback present in face-to-face interactions. These are greatly absent in online communication. Hence, online communication likely engenders feelings of loneliness. Keypoints Problematic internet use (PIU) has been related to loneliness and social networking. Online communication was shown to increase loneliness. Lack of romantic relationships did not explain the association of PIU with loneliness. Poorer family environment did not explain the association of PIU with loneliness. Lack of face-to-face interactions due to time online also did not explain it. Lack of adequate sensory cues and bodily feedback in online contacts might facilitate it.info:eu-repo/semantics/acceptedVersio

Absenteeism and its implications for nursing care in emergency services
The aim of this study was to identify the frequency of absenteeism among nursing teams and its determinants in healthcare emergency services. A cross-sectional study was carried out by means of secondary data from records of a coordination of human resources. Occurrences with 208 nursing professionals were identified. Univariate analysis was carried out with frequency calculation of the variables age, gender, professional category, workplace, and days and reasons for absenteeism. Fisher’s exact test was applied, fixing the error type I in 5%. The mean age of the participants was 47.2 years, with a prevalence of the female gender (79.8%). A total of 5,778 occurrences of absenteeism were found (mean of 28 per professional), and illness was the main determinant for absenteeism (2,671 occurrences; 46.2%). There was a prevalence of short-term absenteeism (3,020 occurrences; 52.3%). The findings observed in emergency services were similar, with a potential impact on planning, workforce, and quality of care
Evaluation of structure and process in care in Diabetes mellitus
Objetivo: Avaliar a atenção à saúde aos pacientes com Diabetes mellitus tipo 2 a partir dos recursos humanos, registros de profissionais e de atividades técnicas em um Centro de Saúde Escola. Metodologia: Estudo avaliativo quantitativo, descritivo por meio de observação e análise de 150 pacientes com DM em um Centro de Saúde Escola no interior paulista. Resultados: A estrutura física segue a maioria das exigências da Agência Nacional de Vigilância Sanitária, os recursos materiais atendem as necessidades em relação às quantidades e qualidade. Em 145 (96.6%) prontuários haviam registros médicos o que aponta a organização do trabalho centrada no modelo biomédico. O registro das medidas antropométricas foi considerado baixo, sendo que em apenas 4 (2.6%) havia a medida da circunferência abdominal. Apenas 5 (3.3%) dos pacientes tiveram consulta com o enfermeiro. Essas consultas foram pontuais enfatizando orientações sobre uso dos medicamentos e aparentemente não se constitui em rotina no serviço. Conclusão: Considerou-se a estrutura do serviço como apropriada, no entanto o processo é um fator a ser revisto pela equipe de saúde.Objective: Evaluate health care to patients with Diabetes mellitus type 2 by means of human resources, records of professional and technical activities in a School Health Center. Methodology: A quantitative, descriptive evaluative study through observation and analysis of 150 patients with DM at a School Health Center in São Paulo. Results: The physical structure follows most of the requirements of the National Health Surveillance Agency; the material resources cater the needs in the quantities and manuquality. The medical records 145 (96.6%) indicates that work organization was focused on the biomedical model. The registration of anthropometric measures was considered low, and in only 4 (2.6%) had the measure of waist circumference. Only 5 (3.3%) patients had consultation with the nurse. These consultations were punctual and highlighting specific guidelines on use of medications and there seems to be not in the service routine. Conclusion: We considered the structure of the service as appropriate but the process is a factor to be reviewed by the health team
Association between habitual use of coping strategies and posttraumatic stress symptoms in a non-clinical sample of college students: A Bayesian approach.
The present study investigated the influences of coping styles on posttraumatic stress symptoms (PTSS) among a sample of non-clinical college students who were exposed to traumatic events. Ninety-nine college students participated in the study. However, the sample used in the analyses consisted of only 37 participants who fulfilled the DSM-IV criterion A for Posttraumatic Stress Disorder (PTSD) diagnosis. The PTSD Checklist-Civilian Version (PCL-C) and the Brief COPE were used to assess the participants' PTSS and habitual use of coping strategies, respectively. Bayesian and frequentist correlations showed that emotion-focused coping style was negatively associated with PTSS, while dysfunctional coping style was positively related to PTSS. In the subsequent linear regression on both statistical framework, dysfunctional coping was the only consistent variable predicting more PTSD symptoms. The findings presented here show that lower use of adaptive coping (emotion-focused) and higher use of dysfunctional coping styles on a daily basis are associated to PTSS severity in a non-clinical sample of college students. According to the Bayesian approach, which permits more generalization of data, dysfunctional coping style is determinant to higher levels of PTSS. These findings add new data to the body of research that highlight the critical role of distinct coping strategies in the severity of PTSS

Previous issue date: 2019Múltipla - Ver em Notas.IMPORTANCE: The effects of intensive care unit (ICU) visiting hours remain uncertain. OBJECTIVE: To determine whether a flexible family visitation policy in the ICU reduces the incidence of delirium. DESIGN, SETTING AND PARTICIPANTS: Cluster-crossover randomized clinical trial involving patients, family members, and clinicians from 36 adult ICUs with restricted visiting hours (<4.5 hours per day) in Brazil. Participants were recruited from April 2017 to June 2018, with follow-up until July 2018. INTERVENTIONS: Flexible visitation (up to 12 hours per day) supported by family education (n = 837 patients, 652 family members, and 435 clinicians) or usual restricted visitation (median, 1.5 hours per day; n = 848 patients, 643 family members, and 391 clinicians). Nineteen ICUs started with flexible visitation, and 17 started with restricted visitation. MAIN OUTCOMES AND MEASURES: Primary outcome was incidence of delirium during ICU stay, assessed using the CAM-ICU. Secondary outcomes included ICU-acquired infections for patients; symptoms of anxiety and depression assessed using the HADS (range, 0 [best] to 21 [worst]) for family members; and burnout for ICU staff (Maslach Burnout Inventory). RESULTS: Among 1685 patients, 1295 family members, and 826 clinicians enrolled, 1685 patients (100%) (mean age, 58.5 years; 47.2% women), 1060 family members (81.8%) (mean age, 45.2 years; 70.3% women), and 737 clinicians (89.2%) (mean age, 35.5 years; 72.9% women) completed the trial. The mean daily duration of visits was significantly higher with flexible visitation (4.8 vs 1.4 hours; adjusted difference, 3.4 hours [95% CI, 2.8 to 3.9]; P < .001). The incidence of delirium during ICU stay was not significantly different between flexible and restricted visitation (18.9% vs 20.1%; adjusted difference, −1.7% [95% CI, −6.1% to 2.7%]; P = .44). Among 9 prespecified secondary outcomes, 6 did not differ significantly between flexible and restricted visitation, including ICU-acquired infections (3.7% vs 4.5%; adjusted difference, −0.8% [95% CI, −2.1% to 1.0%]; P = .38) and staff burnout (22.0% vs 24.8%; adjusted difference, −3.8% [95% CI, −4.8% to 12.5%]; P = .36). For family members, median anxiety (6.0 vs 7.0; adjusted difference, −1.6 [95% CI, −2.3 to −0.9]; P < .001) and depression scores (4.0 vs 5.0; adjusted difference, −1.2 [95% CI, −2.0 to −0.4]; P = .003) were significantly better with flexible visitation. CONCLUSIONS AND RELEVANCE: Among patients in the ICU, a flexible family visitation policy, vs standard restricted visiting hours, did not significantly reduce the incidence of delirium
