Evaluating two morningness scales with item response theory

Using a student sample (n = 692) and an organization sample (n = 180), we scrutinized two morning-evening orientation scales using item response theory (IRT) methods. We used IRT to compare the measurement precision of the Composite Scale (CS) and the Early/Late Preferences Scale (PS). The CS had slightly higher measurement precision at all ranges of orientations, except for extreme morning and evening orientations for which the PS had slightly higher precision. IRT item-level statistics were also computed to try to understand how morning-orientation items functioned. Items that asked questions about morning activities tended to be more discriminating indicators of morning-orientation than items that asked about evening or peak performance activities. Items that involved unpleasant activities were less frequently endorsed than items that involved neutral or enjoyable activities. Implications for measurement of morning-evening orientation are discussed. (C) 2002 Elsevier Science Ltd. All rights reserved.

Attitudes and practices of general practitioners in the diagnosis and management of attention-deficit/hyperactivity disorder

Objective: To assess understanding of, and actual and potential roles in management of attention-deficit/hyperactivity disorder (ADHD) among GPs. Methods: A cross-sectional questionnaire survey of Queensland GPs selected randomly from the Royal Australian College of General Practitioners directory of members was carried out. Main outcome measures were knowledge levels of ADHD, current management practices, referral patterns and self-perceived information and training needs. Results: Three hundred and ninety-nine GPs returned a completed questionnaire (response rate 76%). Roles identified by GPs were: the provisional diagnosis of ADHD and referral to specialist services for confirmation of the diagnosis and initiation of management; assistance with monitoring progress once a management plan was in place; education of the child and their family regarding the disorder; and liaison with the school where necessary. Perceived barriers to increased involvement of GPs were: time and resource constraints of general practice; concerns regarding abuse and addiction liability of prescription stimulants; complex diagnostic issues associated with childhood behavioural problems; and lack of training and education regarding ADHD. Conclusions: General practitioners identify a role for themselves in ADHD care that is largely supportive in nature and involves close liaison with specialist services.

Sexual dysfunction in the Australian population

AIM: To describe the prevalence and forms of sexual dysfunction experienced by Australians, and compare these with people in the United States. METHODS: A cross sectional, telephone interview survey of a randomly selected sample of men (n = 876) and women (n = 908) aged between 18 and 59 years on the electoral roll in all states and territories of Australia (response rate = 61%) was conducted between November 1999 and April 2000. RESULTS: Large proportions of Australian men (55.0%) and women (60.5%) reported at least one sexual problem within the preceding year. More serious sexual dysfunction (> 3 symptoms) was observed in 13.2% of men and 19.7% of women. DISCUSSION: Australia and the USA are similar with regard to the high rate of symptoms of sexual dysfunction observed in the population. The low rate of treatment points to both patient and doctor reluctance to discuss sexual performance and practices.

O impacto da exposição a experiências adversas na infância na ocorrência de dor crônica e depressão na vida adulta

A associação entre experiências adversas na infância e o desencadeamento de depressão ou dor crônica na vida adulta tem sido documentada, assim como a relação entre os sintomas de dor crônica e depressão. No entanto, há poucos estudos avaliando o papel da exposição a experiências adversas na infância na ocorrência dessa comorbidade. O objetivo deste trabalho é avaliar a influência da exposição a experiências adversas na infância na ocorrência de dor crônica, de depressão e na comorbidade dor crônica e depressão na vida adulta, em uma amostra da população geral adulta (maiores de 18 anos) residente na Região metropolitana de São Paulo, Brasil. Os dados são resultantes do Estudo Epidemiológicos dos Transtornos Mentais São Paulo Megacity. Os respondentes foram avaliados usando a versão desenvolvida para o Estudo Mundial de Saúde Mental do Composite International Diagnostic Interview da Organização Mundial da Saúde (WMH-CIDI), que é composto por módulos clínicos e nãoclínicos provendo diagnósticos de acordo com os critérios do Manual Diagnóstico e Estatístico dos Transtornos Mentais 4ª edição (DSM-IV). Um total de 5.037 indivíduos foi entrevistado, com uma taxa global de resposta de 81,3%. Foram realizadas análises descritivas para médias e proporções, e associações (Razões de Chances – OR) entre experiências adversas na infância, dor crônica e depressão através de regressão logística. Todas as análises foram realizadas através do programa estatístico Data Analysis and Statistical Software versão 12.0 (STATA 12.0), com testes bi-caudais com nível de significância de 5%. Uma elevada taxa de prevalência de dor crônica (31%, Erro Padrão [ER]=0.8) foi encontrada, Dor Crônica esteve associada aos transtornos de ansiedade (OR=2,3; 95% IC=1,9 – 3,0), transtornos de humor (OR=3,3; IC=2,6 – 4,4) em qualquer transtorno mental (OR=2,7; 95% IC=2,3 – 3,3). As adversidades na infância estiveram fortemente associadas aos respondentes com dor crônica e depressão concomitante, principalmente quanto ao abuso físico (OR=2,7; 95% IC=2,1 – 3,5) e sexual (OR=7,4; 95% IC=3,4 – 16,1).

Reflexão sobre Estratégias Metodológicas no Ensino do Design e a Função do Desenho em Design

Somos habitantes de um mundo que sofre constantes transformações estruturais em qualquer área. As tecnologias, a globalização e a política dos mercados, deslocam tudo e todos da sua zona de conforto, exigindo constantes adaptações a novos vocabulários e hábitos para os quais não temos antecedentes. Novas competências devem ser adquiridas face às novas exigências, e no ensino, base de uma preparação (pessoal e profissional), impõe-se uma constante revisão de estratégias metodológicas de aquisição e partilha de conhecimento. Neste trabalho apresentaremos uma reflexão sobre o ensino do Design e, especificamente, sobre a função do Desenho nessa área disciplinar. O Design, enquanto disciplina, alargou a sua área de actuação diversificando-se em novos campos como o Design de Experiência ou o Design de Serviço, não bastando ao designer uma formação ligada ao conhecimento tecnológico, ou ao “saber-fazer”. Diversos autores, como Meredith Davis, Don Norman ou Jamie Hobson, alertam para a urgência de uma reflexão aprofundada sobre as estruturas curriculares dos cursos de Design, já que na actualidade “(…) design is more than appearance, design is about interaction, about strategy and about services. Designers change social behavior.” Na passagem de um design centrado na forma, para um design centrado na pessoa (numa estrutura, num serviço, ou numa relação) qual deverá ser a função do desenho num curso de design? Qual deverá ser a sua estrutura programática? Como metodologia de trabalho iremos confrontar perspectivas actuais da teoria e da prática do design que equacionam esta problemática procurando, deste modo, contribuir para a reflexão de estratégias metodológicas no ensino do design no contexto contemporâneo.

Factores relativos al entorno, recursos humanos y sistemas de información y gestión en la adopción del cuadro de mando integral en organizaciones portuguesas

In this paper we aim to identify and analyze a set of variables that can potentially influence the adoption of the Balanced Scorecard (BSC) in Portuguese public and private organizations. These variables are related to the environment (perception of environmental uncertainty), with human resources (support of top management) and, information and management systems (strategic map design and establishment of cause-effect relationships between indicators and perspectives of the BSC). Hypotheses were tested using data obtained from a questionnaire sent to 591 publicly-owned organizations and 549 privately-owned organizations in Portugal, with an overall response rate of 31.3%. The results allow us to conclude that the top management commitment, the development of strategy maps and the establishment of cause-effect relationships are factors that are associated with the implementation of the BSC.

The role of discriminant analysis in the refinement of customer satisfaction assessment

OBJECTIVE: To test discriminant analysis as a method of turning the information of a routine customer satisfaction survey (CSS) into a more accurate decision-making tool. METHODS: A 7-question, 10-multiple choice, self-applied questionnaire was used to study a sample of patients seen in two outpatient care units in Valparaíso, Chile, one of primary care (n=100) and the other of secondary care (n=249). Two cutting points were considered in the dependent variable (final satisfaction score): satisfied versus unsatisfied, and very satisfied versus all others. Results were compared with empirical measures (proportion of satisfied individuals, proportion of unsatisfied individuals and size of the median). RESULTS: The response rate was very high, over 97.0% in both units. A new variable, medical attention, was revealed, as explaining satisfaction at the primary care unit. The proportion of the total variability explained by the model was very high (over 99.4%) in both units, when comparing satisfied with unsatisfied customers. In the analysis of very satisfied versus all other customers, significant relationship was identified only in the case of the primary care unit, which explained a small proportion of the variability (41.9%). CONCLUSIONS: Discriminant analysis identified relationships not revealed by the previous analysis. It provided information about the proportion of the variability explained by the model. It identified non-significant relationships suggested by empirical analysis (e.g. the case of the relation very satisfied versus others in the secondary care unit). It measured the contribution of each independent variable to the explanation of the variation of the dependent one.

Edentulism and shortened dental arch in Brazilian elderly from the National Survey of Oral Health 2003

OBJECTIVE: To describe the distribution of edentulism and estimate the prevalence of functional dentition and shortened dental arch among elderly population. METHODS: A population-based epidemiological study was carried out with a sample of 5,349 respondents aged 65 to 74 years obtained from the 2002 and 2003 Brazilian Ministry of Health/Division of Oral Health survey database. The following variables were studied: gender; macroregion of residence; missing teeth; percentage that met the World Health Organization goal for oral health in the age group 65 to 74 years (50% having at least 20 natural teeth); presence of shortened dental arch; number of posterior occluding pairs of teeth. The Chi-square test assessed the association between categorical variables. The Kruskal-Wallis and Mann-Whitney tests were used to assess differences of mean between number of posterior occluding pairs teeth, macro-region and gender. RESULTS: The elderly population had an average of 5.49 teeth (SD: 7.93) with a median of 0. The proportion of completely edentulous respondents was 54.7%. Complete edentulism was 18.2% in the upper arch and 1.9% in the lower arch. The World Health Organization goal was achieved in 10% of all respondents studied. However, only 2.7% had acceptable masticatory function and aesthetics (having at least shortened dental arch) and a mean number of posterior occluding pairs of 6.94 (SD=2.97). There were significant differences of the percentage of respondents that met the World Health Organization goal and presence of shortened dental arch between men and women. There were differences in shortened dental arch between macroregions. CONCLUSIONS: The Brazilian epidemiological oral health survey showed high rate of edentulism and low rate of shortened dental arch in the elderly population studied, thus suggesting significant functional and aesthetic impairment in all Brazilian macroregions especially among women.

Job quality in Europe: the North-South divide

This paper examines the job quality in Europe. It is based on the results of the Fourth European Foundation Survey on working conditions covering different dimensions including work organisation, job content, autonomy at work, aspects of worker dignity, working time and work-life balance, working conditions and safety in the workplace. The results point to the existence of great diversity in the job quality across Europe and the north-south divide. The job quality differences are related to the variety of social and institutional contexts. The countries of Southern Europe, with their social and institutional contexts falling within the scope of the Mediterranean model, generally present indicators below the European average contrasting Nordic countries having the best job quality indicators.

Users’ dissatisfaction with dental care: a population-based household study

OBJECTIVE To examine whether demographic, socioeconomic conditions, oral health subjectivity and characterization of dental care are associated with users’ dissatisfaction with such are.METHODS Cross-sectional study of 781 people who required dental care in Montes Claros, MG, Southeastern Brazil, in 2012, a city with of medium-sized population situated in the North of Minas Gerais. Household interviews were conducted to assess the users’ dissatisfaction with dental care (dependent variable), demographic, socioeconomic conditions, oral health subjectivity and characterization of dental care (independent variables). Sample calculation was used for the finite population, with estimates made for proportions of dissatisfaction in 50.0% of the population, a 5.0% error margin, a non-response rate of 5.0% and a 2.0% design effect. Logistic regression was used, and the odds ratio was calculated with a 5% significance level and 95% confidence intervals.RESULTS Of the interviewed individuals, 9.0% (7.9%, with correction for design effect) were dissatisfied with the care provided. These were associated with lower educational level; negative self-assessment of oral health; perception that the care provider was unable to give dental care; negative evaluation of the way the patient was treated, the cleanliness of the rooms, based on the examination rooms and the toilets, and the size of the waiting and examination rooms.CONCLUSIONS The rate of dissatisfaction with dental care was low. This dissatisfaction was associated with socioeconomic conditions, subjectivity of oral health, skill of the health professionals relating to the professional-patient relationship and facility infrastructure. Educational interventions are suggested that aim at improving the quality of care among professionals by responsible agencies as is improving the infrastructure of the care units.

ERICA: smoking prevalence in Brazilian adolescents

ABSTRACT OBJECTIVE To estimate the prevalences of tobacco use, tobacco experimentation, and frequent smoking among Brazilian adolescents. METHODS We evaluated participants of the cross-sectional, nation-wide, school-based Study of Cardiovascular Risks in Adolescents (ERICA), which included 12- to 17-year-old adolescents from municipalities of over 100 thousand inhabitants. The study sample had a clustered, stratified design and was representative of the whole country, its geographical regions, and all 27 state capitals. The information was obtained with self-administered questionnaires. Tobacco experimentation was defined as having tried cigarettes at least once in life. Adolescents who had smoked on at least one day over the previous 30 days were considered current cigarette smokers. Having smoked cigarettes for at least seven consecutive days was an indicator for regular consumption of tobacco. Considering the complex sampling design, prevalences and 95% confidence intervals were estimated according to sociodemographic and socio-environmental characteristics. RESULTS We evaluated 74,589 adolescents. Among these, 18.5% (95%CI 17.7-19.4) had smoked at least once in life, 5.7% (95%CI 5.3-6.2) smoked at the time of the research, and 2.5% (95%CI 2.2-2.8) smoked often. Adolescents aged 15 to 17 years had higher prevalences for all indicators than those aged 12 to 14 years. The prevalences did not differ significantly between sexes. The highest prevalences were found in the South region and the lowest ones, in the Northeast region. Regardless of sex, the prevalences were found to be higher for adolescents who had had paid jobs, who lived with only one parent, and who reported having been in contact with smokers either inside or outside their homes. Female public school adolescents were found to smoke more than the ones from private schools. CONCLUSIONS Tobacco use among adolescents is still a challenge. Intending to reduce the prevalence of tobacco use among young people, especially the ones under socioeconomic vulnerability conditions, Brazil must consolidate and increase effective public health care measures.
