Método de captura e recaptura: nova metodologia para pesquisas epidemiológicas
Dunn,John; Andreoli,Sérgio Baxter;
Revista de Saúde Pública , 1994, DOI: 10.1590/S0034-89101994000600009
Abstract: although capture-recapture method is not new, their use in epidemiological studies has so far been limited. the method was developed by animal ecologists to estimate the size of various species populations, but in recent years it has been used to measure the incidence and prevalence of a variety of non-communicable diseases. capture-recapture allows more accurate estimates to be made than is the case with traditional methods and is more cost-effective. the method is ideally suited to studying rare or elusive populations, such as intravenous drug misusers; but they are highly adaptable and have been used to study populations as diverse as street working prostitutes and the human red-cell volume. the objectives of this review are to explain the mathematical theory behind capture-recapture, give examples of its use and application in clinical epidemiology and out line some of the modifications that have been made to the theory, which take into account the complex nature of samples used in clinical research. an increasing number of medical epidemoilogists have started to use the method, and its potencial for future epidemiological research is enormous.
Método de captura e recaptura: nova metodologia para pesquisas epidemiológicas
Dunn John,Andreoli Sérgio Baxter
Revista de Saúde Pública , 1994,
Abstract: O método de captura e recaptura, embora n o seja novo, tem sido pouco usado em estudos epidemiológicos. Trata-se de método bem adaptável e adequado para estudar popula es incomuns ou esquivas, como usuários de drogas endovenosas. Tem sido usado para estudar popula es diversas como prostitutas que trabalham na rua ou volume de células vermelhas no homem. Permite ainda estimar a incidência e a prevalência de doen as de forma mais precisa do que os métodos tradicionais e com uma melhor rela o custo-benefício. Devido à sua relevancia dentro do campo da epidemiologia, decidiu-se realizar uma revis o sobre esse método, enfocando a história, as principais aplica es e apontando as suposi es teóricas que o fundamentam. Seu potencial para futuras pesquisas epidemiológicas é promissor.

Abstract: alopecia areata is a common dermatological disorder characterized by the rapid loss of hair in single or multiple patches. hair loss is often on the scalp, but can also occur in other areas of the body. psychological traumas have often been cited as precipitating factors. an evaluation of a group of twelve patients diagnosed with alopecia areata was undertaken using psychological interviews and the rorschach test, comprehensive system, with the aim being to identify the condition of the patients’ personalities while handling stress. all patients reported having experienced traumatic events which can be considered catalysts of alopecia areata symptoms, and nine demonstrated clear evidence of serious difficulty in stress management.

Ciência & Saúde Coletiva , 2006, DOI: 10.1590/S1413-81232006000300028
Abstract: the goal of this paper is to review the school-based drugs misuse prevention programs, and to establish a connection with the "health promotion" and "health promoting school" concepts, in an attempt to create a new proposal. there are several models of preventive intervention, but the results of its evaluations show little improvement. the most hopeful programs imply in giving up the restrict focus of prevention (of a specific disease) to adopt the health promotion concept. the application of the health promotion concept in the school environment resulted in the health promoting school concept, which can be defined as a school that has an organized set of policies, procedures, activities, and structures, designed to protect and promote the health and well-being of all school community members. the "harm reduction" proposal, as a prevention strategy, come together the health promoting school proposal, and in this way our proposal is a set of health promotion actions that includes: wider and progressive goals; breaking the manichaeism; inclusive actions; community partnerships including many sectors of society; youth autonomy; and the focus on the person in all its complexity, not only on the substance use or misuse. this proposal aims all students, regardless if they had or not already tried or they still are using any psychoactive substance.
Knowledge and attitudes related to drug abuse and prevention displayed by public school educators
Moreira, Fernanda Gon?alves;Silveira, Dartiu Xavier da;Andreoli, Sérgio Baxter;
Revista Brasileira de Psiquiatria , 2009, DOI: 10.1590/S1516-44462009000200003
Abstract: objective: to investigate the connection between knowledge about and the attitudes towards drug abuse by students displayed by public school educators in brazil. method: cross-sectional study, with probabilistic sampling encompassing 20% of the municipal elementary schools located in the city of s?o paulo from which educators were enrolled to answer three questionnaires: 1) professional and personal data; 2) assessment of their attitudes in drug abuse situations; 3) assessment of their knowledge on drug abuse. results: considering possible values between -17 and +21, professionals scored 11.5 ± 3.8 in the attitudes scale. these values correspond to more empathic attitudes. scores in the knowledge on drugs scale were 55.2 ± 12.5 (possible values: 0 to 100). correlation between the attitudes scale and the time spent working as education professionals was -0.288 (p < 0.01). the difference in the means in the attitude scale according to professional academic qualifications was statistically significant (-1.93, t = 2.26; gl = 80; p < 0.05). conclusion: the level of knowledge about drugs displayed by educators was average and not influenced by the professional's academic qualifications. in contrast, their attitudes were predominantly empathic and directly associated to their academic qualifications and inversely associated to the amount of time they had spent in that position.

Carvalho, Hudson Wander de;Patrick, Christopher J.;Jorge, Miguel Roberto;Andreoli, Sérgio Baxter;
Revista Brasileira de Psiquiatria , 2011, DOI: 10.1590/S1516-44462011000100012
Abstract: objective: investigate the structural coherency of the 60-item version of the general health questionnaire via exploratory and confirmatory factor analyses. method: the study design is a cross-sectional survey. a random sample of 146 individuals from the city of divinópolis-mg volunteered to participate in the present study and responded to the 60-item version of the general health questionnaire adapted and validated for use in brazil. statistics consisted of exploratory and confirmatory factor analysis. reliability was estimated using cronbach's alpha method. results: alpha coefficients for all five content scales of the general health questionnaire were high (α > 0.8). for four of the five scales, a unifactorial model of constituent items provided a good fit to the data. items comprising the fifth scale, psychic stress, exhibited a two-correlated factor structure. a factor analysis of scores for the five scales yielded strong evidence of coherency, with all scales loading substantially on a single common factor. conclusion: the general health questionnaire shows good psychometric coherency as evidenced by high internal consistency and unidimensionality of all but one of its constituent scales, and uniformly high loadings of all scales on a single overarching factor. these results are consistent with prior findings from the general health questionnaire developmental study and brazilian adaptation studies.
Situa??es relacionadas ao uso indevido de drogas nas escolas públicas da cidade de S?o Paulo
Moreira,Fernanda Gon?alves; Silveira,Dartiu Xavier da; Andreoli,Sérgio Baxter;
Revista de Saúde Pública , 2006, DOI: 10.1590/S0034-89102006000600010
Abstract: objective: to explore situations, attitudes and behavior of public elementary school education supervisors concerning psychoactive substance misuse. methods: the study was carried out in the city of s?o paulo, southeastern brazil, in 2002. data were collected using a semi-structured questionnaire applied to eight key informants in the administrative area experienced in education supervision. qualitative content analysis with ethnographic reference was conducted. results: most discourses show that knowledge transmission is thought as essential for drug use prevention, though supervisors reported being ill-informed on this subject. the most frequent attitudes toward drug users are impotence and inability to act and sometimes a repressive attitude. these are motivated by misinformation and fear due to mistaken association of drug users and criminals. in situations indirectly related to drug abuse (family and behavior problems) more understanding and inclusive attitudes are reported, following the harm reduction paradigm. conclusions: theoretical capacity building of educators for preventive attitudes would support their skills developed through dealing with situations (in)directly related to drug abuse in schools. thus, educators would feel more confident to make interventions for harm or risk reduction among drug users.

Ballester, Dinarte Alexandre;Filippon, Ana Paula;Braga, Carla;Andreoli, Sérgio Baxter;
Sao Paulo Medical Journal , 2005, DOI: 10.1590/S1516-31802005000200008
Abstract: context and objective: within the context of primary health care and mental disorders, our aim was to study the opinions of general practitioners regarding attendance of people with mental health problems. design and setting: qualitative focal group study among primary care services in the cities of porto alegre and parobé, state of rio grande do sul. methods: a deliberately selected sample of 41 general practitioners who were working in basic health services met in focal groups. two videos were presented, which simulated consultations for patients with depression and psychoses. the discussions about the identification and handling of mental health problems were recorded and assessed via content analysis. results: the opinions related to the difficulties of diagnosing and treating mental problems, the involvement of relatives in caring for patients, the difficulty of compliance with the treatment, the uncertainty experienced by physicians and the difficulty of referring patients to specialized services. conclusions: the general practitioners indicated that they perceived the mental health problems among their clientele, but the diagnosis and treatment of these problems are still seen as a task for specialists. the challenge of continuing education on mental health requires methods of interactive and critical teaching, such as the problem-based approach.

Abstract: O objetivo foi estudar a confiabilidade do inventário de sintomas psiquiátricos do DSM-III aplicado em amostras representativas da popula o geral de três cidades brasileiras. Foram utilizados os métodos do entrevistador-observador e de consistência interna para medir a confiabilidade. Os diagnósticos de ansiedade generalizada, na vida (k = 0,46), no ano (k = 1,00), depress o na vida (k = 0,77) e os diagnósticos de abuso e dependência de álcool na vida (k = 1,00) foram confiáveis de forma consistente nos dois métodos empregados. Os diagnósticos de agorafobia (k = 1,00), fobia simples (k = 0,77), transtorno psicótico n o esquizofrênico (k = 1,00) e o de fatores psicológicos que afetam o físico (1,00), todos feitos para a vida, apresentaram confiabilidade excelente medidos por meio do Kappa. O principal problema de medir a confiabilidade em estudos populacionais é a baixa prevalência de alguns diagnósticos que resulta em uma pequena variabilidade nas respostas positivas, o que impossibilita o cálculo do Kappa. Por causa disso, apenas 11 dos 39 diagnósticos que comp em o inventário puderam ser examinados. Recomenda-se a utiliza o do método de teste e re-teste com um tempo curto entre as entrevistas para diminuir esse problema.
