O presente estudo buscou investigar o impacto da resiliência e da autoeficácia sobre o burnout em profissionais de enfermagem. O constructo resiliência no contexto do trabalho refere-se a capacidade de adaptação de forma positiva frente às adversidades que ocorrem no ambiente laboral. A autoeficácia no trabalho representa a percepção do indivíduo sobre as suas próprias competências na execução de tarefas. Já o burnout é compreendido como uma síndrome específica do meio laboral como consequência da cronificação do estresse ocupacional, apresentando três dimensões: a exaustão, o cinismo (despersonalização) e a baixa realização profissional. A amostra da pesquisa foi composta por 82 trabalhadores da área de enfermagem que trabalham em Unidades de Pronto Atendimento UPA s localizadas no estado do Acre. A maior parte dos participantes é do sexo feminino (78%), com idade média de 31 anos (DP=6,8). Para a mensuração das variáveis foram utilizadas a Escala de Resiliência no Trabalho, a Escala de Autoeficácia no Trabalho e a Escala de Caracterização do Burnout, e para coletar os dados sociodemográficos foi aplicado um questionário de autorresposta construído para este estudo. Os dados foram submetidos a análises exploratórias e descritivas, análise de variância (ANOVA), análise de correlação de Pearson e regressão linear múltipla padrão. Os resultados indicaram que os profissionais de enfermagem apresentaram níveis médios de resiliência, autoeficácia e dos componentes exaustão e baixa realização profissional do burnout; e, por sua vez, baixo nível de despersonalização. Constatou-se também correlação entre autoeficácia com dois dos três fatores do burnout: exaustão emocional e decepção no trabalho. Os achados ainda revelaram que resiliência e autoeficácia conjuntamente predizem significativamente ambos os fatores de burnout, exaustão e decepção. No entanto, a variável responsável por esta explicação foi autoeficácia no trabalho, pois apenas ela foi estatisticamente significante para explicar os dois componentes do burnout relatados. Conclui-se que os profissionais que apresentam maior autoeficácia são os que menos sucumbem ao burnout, essa síndrome tão devastadora que ataca de maneira impiedosa os profissionais que lidam no atendimento às pessoas.

A fadiga é um sintoma inespecífico, encontrado com freqüência na população. Ela é definida como sensação de cansaço físico profundo, perda de energia ou mesmo sensação de exaustão, e é importante a sua diferenciação com depressão ou fraqueza. Os transtornos depressivos e ansiosos constituem os transtornos psiquiátricos mais freqüentes no idoso, e quase sempre dão lugar a conseqüências graves neste grupo etário. Este estudo visa avaliar a influência da ansiedade e depressão sobre o desencadeamento de fadiga e evolução de problemas de saúde e de comportamentos peculiares ao processo de envelhecimento. Trata-se de um estudo, do tipo caso-controle investigando ansiedade, depressão e fadiga. Foram avaliados 61 indivíduos com 60 anos de idade ou mais. Um grupo controle constituído por 60 indivíduos jovens (idade até 35 anos), foram selecionados entre estudantes do Centro Universitário de Santo André que responderam um Questionário de Características Gerais, um Inventário de Ansiedade traço-estado, um Inventário de Depressão de Beck e uma Escala de Severidade de Fadiga. O grupo de idosos apresentou um escore significativamente maior em relação ao grupo controle na escala de severidade de fadiga. O grupo de idosos apresentou escore médio de 36,87 ± 14,61 enquanto o grupo controle apresentou escore médio de 31,47 ± 12,74 (t = 2,167; df = 119; p = 0,032). No entanto, o grupo de idosos apresentou escores significativamente maiores na escala de Beck (10,54 ± 8,63) em relação aos controles (6,83 ± 7,95); t = 2,455; df = 119; p = 0,016). Analisando-se apenas o grupo de indivíduos idosos, observou-se uma correlação significativa entre os escore da escala de severidade de fadiga e a escala de depressão de Beck (correlação de Pearson = 0,332; p = 0,009). Ainda trabalhando apenas com o grupo de indivíduos idosos, observou-se um escore significativamente maior da escala de severidade de fadiga naqueles indivíduos que praticavam atividade física regular, sendo, escore médio de 31,55 ± 13,36; (t = 2,203; df = 58; p = 0,032). A partir da análise dos resultados deste estudo pôde-se concluir que o grupo de indivíduos idosos apresentam estatisticamente significante escore maior, quando comparado com o grupo controle, apresentando mais sintomas de fadiga e depressão. Estes sintomas de fadiga ocorreram em conjunto com sintomas depressivos sugerindo uma possível correlação entre estes. Quando se observou apenas os idosos, esta correlação foi confirmada. Analisado-se ainda somente o grupo de indivíduos idosos observa-se que o grupo de idosos que praticam atividade física regularmente apresentam menos sintomas fadiga que o grupo que não pratica atividade física.(AU)

The presence of peripheral arterial disease (PAD) increases the risk and vulnerability to adverse clinical outcomes in the elderly. Like this, we investigated the relationship between functional performance and indicators of PAD in elderly women. METHODS: Cross-sectional study in which 54 elderly were assessed by questionnaire mini mental state examination, Short Phisical Performance Battery (SPPB), ankle-brachial index (ABI), human activity profile (HAP) and Edinburgh questionnaire. Statistical analysis was performed using ANOVA, t test and Pearson correlation. We considered p <0.05 as significance level. RESULTS: The mean age SPPB and ABI were 69.2 (± 6.9) years, SPPB 9.42 (± 2.55) and ABI 1.04 (± 0.14). The prevalence of PAD was 16.3%. There was a significant correlation between ABI and gait speed (r = 0.75, p = 0.001) and between PAH with SPPB (p = 0.001). CONCLUSIONS: It is suggested that the decline in functional performance in older, expressed in gait velocity component of the SPPB, is related to the presence of PAD

This research had as main aim to verify the motivational quality of music students at four public universities in the Northeast of Brazil, based on the Self-Determination Theory (SDT). This perspective was proposed by Edward Deci and Richard Ryan (1985, 2000, 2008a, 2008b), and considers the qualitative aspects of motivation. It defends that the individuals have a natural tendency to self-regulation; it adopts the concept of internalizations through a continuum of self-determination conceived in the mini-theory of organismic integration. The research presents a descriptive, exploratory and correlational approach. To collect data, it was submitted a self-report questionnaire, based on the Academic Motivational Scale, translated and validated by Guimarães and Bzuneck (2008), which allow us to verify the motivation types according to a selfdeterminational continuum. According to this application, the instrument has shown evidence of satisfactory validity, with a good internal consistence and correlations from weak to moderate scale. The obtained data were collected from 380 music students, analyzed through a descriptive and inferential statistics, considering a few procedures: frequencies, averages, standard deviation, factorial analysis, internal consistence analysis through Cronbach Alpha, Pearson’s correlational analysis and variance analysis. The analyzed data show that high averages in the evaluation of self-determined motivation and low evaluation in demotivation and less autonomy motivation. Many students revealed strong intention to conclude the course. It was identified less autonomous motivation and more motivation among the students with intention to work in other areas, some of them concluded the final training process in Music Course, and say that they are in this course because they had no other option. We conclude that those graduated in Music Course, represented in this sample, show a good motivational quality. But after a few time there is a tendency in decreasing autonomous motivation because of some requirements of an academic course. In this sense, the courses must create strategies to maintain a self-determined behavior so that students can realize their autonomous motivation, identifying its importance, value and meaning along the Course.

Advanced age may become a limiting factor for the maintenance of rhythms in organisms, reducing the capacity of generation and synchronization of biological rhythms. In this study, the influence of aging on the expression of endogenous periodicity and synchronization (photic and social) of the circadian activity rhythm (CAR) was evaluated in a diurnal primate, the marmoset (Callithrix jacchus). This study had two approaches: one with longitudinal design, performed with a male marmoset in two different phases: adult (three years) and older (9 y.o.) (study 1) and the second, a transversal approach, with 6 old (♂: 9.7 ± 2.0 y.o.) and 11 adults animals (♂: 4.2 ± 0.8 y.o.) (study 2). The evaluation of the photic synchronization involved two conditions in LD (natural and artificial illuminations). In study 1, the animal was subjected to the following stages: LD (12:12 ~ 350: ~ 2 lx), LL (~ 350 lx) and LD resynchronization. In the second study, the animals were initially evaluated in natural LD, and then the same sequence stages of study 1. During the LL stage in study 2, the vocalizations of conspecifics kept in natural LD on the outside of the colony were considered temporal cue to the social synchronization. The record of the activity was performed automatically at intervals of five minutes through infrared sensor and actimeters, in studies 1 and 2, respectively. In general, the aged showed a more fragmented activity pattern (> IV < H and > PSD, ANOVA, p < 0.05), lower levels of activity (ANOVA, p < 0.05) and shorter duration of active phase (ANOVA, p < 0.05) in LD conditions, when compared to adults. In natural LD, the aged presented phase delay pronounced for onset and offset of active phase (ANOVA, p < 0.05), while the adults had the active phase more adjusted to light phase. Under artificial LD, there was phase advance and greater adjustment of onset and offset of activity in relation to the LD in the aged (ANOVA, p < 0.05). In LL, there was a positive correlation between age and the endogenous period () in the first 20 days (Spearman correlation, p < 0.05), with prolonged  held in two aged animals. In this condition, most adults showed free-running period of the circadian activity rhythm with  < 24 h for the first 30 days and later on relative coordination mediated by auditory cues. In study 2, the cross-correlation analysis between the activity profiles of the animals in LL with control animals kept under natural LD, found that there was less social synchronization in the aged. With the resubmission to the LD, the resynchronization rate was slower in the aged (t-test; p < 0.05) and in just one aged animal there was a loss of resynchronization capability. According to the data set, it is suggested that the aging in marmosets may be related to: 1) lower amplitude and greater fragmentation of the activity, accompanied to phase delay with extension of period, caused by changes in a photic input, in the generation and behavioral expression of the CAR; 2) lower capacity of the circadian activity rhythm to photic synchronization, that can become more robust in artificial lighting conditions, possibly due to the higher light intensities at the beginning of the active phase due to the abrupt transitions between the light and dark phases; and 3) smaller capacity of non-photic synchronization for auditory cues from conspecifics, possibly due to reducing sensory inputs and responsiveness of the circadian oscillators to auditory cues, what can make the aged marmoset most vulnerable, as these social cues may act as an important supporting factor for the photic synchronization.

The fast growth of the elderly population is a reality throughout the world and has become one of the greatest challenges for contemporary public health. When considering the increased life expectancy and the aging as a multidimensional phenomenon, one should highlight the need to investigate if the increase of longevity is associated with satisfactory levels of Quality of Life (QOL). This study has the objective of assessing the QOL of elderly people from the Paraíba’s Western Curimataú microregion, explained by its health and living conditions. This is a cross-sectional and observational study with quantitative design held with 444 elderly people from five cities: Barra de Santa Rosa, Cuité, Nova Floresta, Remígio e Sossego. In order to obtain information, the following instruments were used: I) Questionnaire for collection data related to the elderly population, for sociodemographic, clinical and behavioral characteristics; and II) WHOQOL-Old questionnaire, with a view to measuring and assessing QOL. Data were processed on the IBM-SPSS Statistics 20.0 software by means of the ANOVA (one-way), Student’s t, Mann-Whitney, Kruskal-Wallis and Pearson’s correlation tests, with p-values<0,05 accepted as being statistically significant. The results indicate a good global QOL (ETT=65,69%), with better assessment by elderly men, aged between 60 and 74 years, married, living with partner and children, without caregiver, physical activity practitioners, with up to one health problem before an aspect of multimorbidity and with very good and/or good assessment of basic needs. The self-reported stress showed a negative significant correlation before the global QOL, where the greater the perception of stress, the worse the assessment of QOL. In the faceted assessment of QOL, the Sensory Operation showed the best performance (ETF= 68,86%) and the Social Participation (SP) the worst (ETF=60,37%). In the multiple linear regression model, SP is singly responsible for 51,8% (R2=0,518) of explanation of the global QOL. In the intercorrelation among the WHOQOL-Old facets, only Death and Dying did not reveal significance. The harmony highlighted among the facets raises the need to ensure a comprehensive health care for the elderly population, especially in understanding the social participation as an intrinsic part of the QOL and that it requires the re-discussion and reconstruction of individual and collective, family and community, political and government actions. Hence, guaranteeing an active, healthy and participatory aging, with QOL, is the major challenge.

This thesis aimed to contribute to the discussion about the relationship between agricultural production structure, occupation and poverty in Brazil, specifically in the state of Minas Gerais, in 2010. The issue of employment is becoming increasingly challenging in the face of ongoing modernization process in agriculture, capital intensive and labor saver looking levels ever higher production and productivity. The productive inclusion can be an effective way to exit from poverty (the work is often the only asset of the poor). In this sense, we sought to investigate what activities or groups of activities occupied a larger number of people and generated higher yields and can potentially have contributed to a lower incidence of poverty. The basis for primary data was the 2010 Population Census (microdata). To achieve the objectives we used descriptive analysis, Pearson correlation coefficients and quantile regressions. Among the main findings highlight that agriculture occupied more and generated higher overall income than ranching presented more precarious, despite having lower average incomes and income percentile values, greater heterogeneity and instability, as well as higher proportions of poor. Overall, commodities showed greater formalization and lower poor proportions. In the case of agriculture, commodities activities occupied less, generated lower mass income and middle-income (although income percentiles slightly larger and more informality) and had lower poverty indicators than non-commodity (more heterogeneous rents). In livestock, commodities had higher percentages of occupation, income (although middle-income values and percentiles slightly smaller), and smaller proportions of poor than non-commodity (more heterogenous). In terms of occupation and income stood out the farming activities unspecified (non-commodity), the coffee growing and cattle (commodities). The cultivation of coffee and cattle had the lowest poverty indicators. agricultural production diversification indicators showed positive correlations with the occupation in activities not commodities (only), but also with the proportion of poor, indigent and concentration of income. In addition, the occupation in not commodities showed positive correlations with poverty indicators. It is noteworthy that the occupations in soybeans, coffee and fruit showed negative correlation coefficients with the indicators of poverty, indigence and gini. Finally, among the agricultural activities, there was to go to occupied in agricultural activities not commodities for commodity would be 'more equalizer' (decreasing coefficients over the distribution of income) than for cattle. The occupation in livestock (mostly non-commodity) would generate greater impact on the lower income deciles, but their coefficients grow back in the last deciles, which shows its most perverse character. Among the activities that would affect more strongly the lower deciles and less the higher deciles stand out pig farming, poultry, citrus cultivation, coffee and sugar cane. The cattle and the cultivation of soy, had the highest rates, but they grow back in the last deciles, which shows a more wicked character.

The consumption of a product is directly linked to its quality, and are required to comply with quality standard regulations. In chicken "griller" which comes from industrial strains, selected for best growth performance, shot with up to 35 days old and weighing 1,400kg, they have not been reported in the literature a number of quality aspects This study aimed determine the muscle transformation time in the flesh in chickens "griller" incidence of meat defects, "PSE" (pale, soft and exdudative) and "DFD" (dark, firm and dry) and their correlation between different window times slaughter (total time between beginning of the fasting and the time of slaughter) and pH curve, four different times post mortem. The base data for the study was composed of information of 208 chickens, collected between August and September 2014, in a slaughterhouse slaughtering chickens in the middle region of Triangulo Mineiro and Alto Paranaíba. We used the Minitab 17.1.0 program for the development of descriptive statistical analysis and Pareto charts. The Pearson correlation was used to evaluate the linear relationship between two variables and Excel 2013, Microsoft Office®, to produce tables and graphs. The analysis consisted of 11 chickens cities and the distance to the poultry slaughterhouse ranged from 24.5 km to 123 km. It was observed that the pH curve decays gradually until time 5horas after slaughter, and its increase was 24, indicating the transformation of the muscle meat. The incidence of regular meat was 39.9%, "DFD" 30.3% and "PSE" 29.8%. For "DFD" meat, it was observed that factors: low ambient temperature, longer transportation and fast window and mileage at dirt road, contributed to its occurrence (p <0.05). For "PSE" meat, it was observed that lower body weight factors, longer transport favored frequency (p <0.05) of the meat defect. There was no significant correlation in variance analysis between distance, waiting time at rest shed and humidity related to meat defects (p> 0.05). This high incidence of defects meat may be due to pre-slaughter stress factors.

Chronic non-communicable diseases represent a major public health problem, requiring more effective investigation and control by government agencies. The aim of this study was to correlate the mortality rate for oral cancer in Brazilian State capitals from 1998 to 2002 with socioeconomic factors collected in the 2000 census, using an ecological study design. Data were obtained from the Mortality Information System from 1998 to 2002. Social factors were taken from the Brazilian Human Development Atlases. After data collection, statistical analysis was performed using Pearson's correlation index. The findings included positive and significant correlations among the socioeconomic indicators (Municipal Human Development Index - MHDI, MHDI-income, MHDI-education, MHDI-life expectancy, and per capita income), and negative and significant correlations with the socioeconomic indicators Gini Index and infant mortality. Despite the study’s limitations and probable underreporting in less developed State capitals, the study found significant statistic correlations between the selected socioeconomic indicators and the oral cancer mortality rate___________________________RESUMO As doenças crônico-degenerativas representam um grande problema de saúde pública, necessitando de levantamento e controle mais efetivos destas enfermidades por parte dos órgãos públicos. O objetivo deste estudo foi correlacionar os índices de mortalidade por câncer oral nas capitais do Brasil no período de 1998 a 2002 com indicadores sócio-econômicos do Censo Demográfico de 2000 , por meio de um estudo do tipo ecológico. Os dados foram extraídos do Sistema de Informação de Mortalidade (Ministério da Saúde/DATASUS), para os anos de 1998-2002. Os indicadores sócio-econômicos foram obtidos a partir do Atlas do Desenvolvimento Humano no Brasil. Após coleta dos dados, a análise estatística foi realizada usando-se o índice de correlação de Pearson. Observaram-se corre- lações positivas e significativas entre os indicadores sócio-econômicos (Índice de Desenvolvimento HumanoMunicipal – IDH-M, IDH-M renda, IDH-M educação, IDH-M longevidade e renda per capita), e correlação negativa e significante para os indicadores sócio-econômicos índice de Gini e mortalidade infantil. Apesar das limitações do estudo e da provável problemática de sub-registros nas capitais menos desenvolvidas, o presente trabalho encontrou correlações estatisticamente significantes entre os indicadores sócio-econômicos selecionados e o índice de mortalidade por câncer oral

Objetivos: A música, incomum pela sua ubiquidade e antiguidade, constitui uma das atividades humanas que ocupa um lugar significativo nas diversas culturas e vida diária. Geralmente agradável para grande parte das pessoas, produz numerosos e desmedidos efeitos, na sua maioria positivos para o ser humano. Esta investigação teve como objetivo principal estudar a relação entre alguns dos diferentes géneros musicais e os de traços de personalidade de jovens e de adultos com idades compreendidas entre os 18 e os 38 anos, fluentes em português. A investigação pretendeu descrever as preferências musicais em função da idade, género, estado civil e habilitações literárias; identificar os contextos, os períodos e as atividades mais comuns durante a escuta de música; reconhecer se a música é uma das atividades de lazer mais importantes para o grupo estudado; conhecer quais as razões mais frequentes apontadas pelos sujeitos para ouvir música; estudar a perceção que as pessoas têm sobre a influência da música na violência e no consumo de substâncias; verificar se os sujeitos consideram as preferências musicais como um fator importante e revelador de informações sobre a personalidade; avaliar o impacto e relação das preferências musicais com a personalidade e verificar quais os pares de emoções mais comuns, sentidos durante a escuta musical, e respetiva intensidade. Metodologia: A amostra foi constituída por 320 indivíduos com idades compreendidas entre os 18 e os 38 anos sendo a faixa etária mais comum a que se situa entre os 24 a 29 anos, maioritariamente do sexo feminino, solteiros, de nacionalidade portuguesa, detentores ou a frequentar um curso superior, nas áreas das ciências sociais/serviços ou exatas e tecnológicas. Os participantes aceitaram responder voluntariamente a uma bateria de testes (QCS, EPI, QMQEC e STOMP-PT). Para a caracterização da amostra, determinaram-se frequências absolutas e relativas ou valores médios e desvios-padrão. A normalidade da distribuição das pontuações médias dos instrumentos foi validada com o teste de Kolmogorov-Smirnov com correção de Lilliefors. A consistência interna estudou-se através do Alpha de Cronbach e da fórmula de Kuder Richarson. As diferenças entre grupos foram avaliadas recorrendo a uma ANOVA, a intensidade e magnitude das relações entre variáveis determinou-se através do coeficiente Eta quadrado (e 2) e com o coeficiente de correlação de Pearson avaliou-se a associação entre as variáveis em estudo. Resultados: Observou-se que a música energética é a mais típica dos escalões etários mais jovens, sendo que a rebelde trespassa todas as gerações, revelando os mais velhos também uma forte preferência pela música reflexiva. As escolhas musicais parecem não ser influenciadas pelo sexo e estado civil. Os indivíduos menos escolarizados parecem preferir músicas do tipo energético, excluindo as convencionais enquanto os detentores de maiores habilitações preferem os estilos reflexivos e rebeldes. É em casa, no quarto, ao fim de semana e quando estão sozinhos que os participantes mais ouvem música, constituindo esta a mais frequente atividade de lazer, por ser uma atividade essencial para a existência, não apelando à violência e ao consumo de substâncias e revelando as preferências musicais aspetos da personalidade. Encontraram-se diferenças estatisticamente significativas entre as dimensões da preferência musical e os traços de personalidade, sendo a música energética a que mais se destaca na extroversão e a rebelde no neuroticismo. Não se obtiveram resultados estatisticamente significativos entre os tipos de música e as emoções. Conclusão: Os resultados devem ser vistos a título de ensaio e como introdutórios, seguindo no entanto os referidos na literatura quer ao nível das preferências por idade, sexo e habilitações literárias, quer ao nível do contexto onde é ouvida, quer ainda entre as dimensões de preferência musical e traços de personalidade. / Aims: Music, unusual for its ubiquity and age, is one of the human activities that occupies a significant place in different cultures and daily life. Generally pleasant to most people, produces many and huge positive effects in humans. This investigation aimed to study the relationship between some of the different music preferences and personality types of young and adults aged between 18 and 38 years, fluent in Portuguese. The research intended to describe the musical preferences based on age, gender, marital status and educational attainment; identify contexts, periods and the most common activities during music listening; recognize the music as one of the most important leisure activities for the group studied; know which are the most frequent reasons given by the subjects to listen to music; study the perception that people have about the influence of music on violence and substance use; check whether the subjects consider the musical preferences as a major factor that reveals information about personality; assess the impact and relationship of musical preferences with the personality and see which pairs of most common emotions are felt during music listening, and its respective intensity. Methods: The sample consisted of 320 individuals aged between 18 and 38 years being the most common age group of between 24 to 29 years, mostly female, single, Portuguese, holders or to attend a higher education in the areas of social / services or exact science. Participants voluntarily agreed to answer a battery of tests (QCS, EPI, QMQEC and STOMP-PT). To characterize the sample, they were determined absolute and relative frequencies and mean values and standard deviations. The normality of the average scores of the instruments has been validated with the Kolmogorov-Smirnov test with Lilliefors correction. Internal consistency was studied using Cronbach's alpha and Kuder Richardson formula. Differences between groups were assessed using an ANOVA, intensity and magnitude of the relationship between variables was determined by Eta squared coefficient and the Pearson correlation coefficient evaluated the association between the study variables. Results: It was observed that the energetic music is the most usual among the younger age groups, and the rebel pierces all generations, revealing the older ones a strong preference for reflective music. The musical choices do not seem to be influenced by sex and marital status. The less educated individuals seems to prefer the energetic type songs, excluding conventional, holders of higher qualifications prefer reflective and rebellious styles. It is at home, in the room, on the weekends and when they are alone that participants listen more music, making this the most common leisure activity, the essential for existence, not calling for violence and substance use and revealing aspects of personality. We found significant differences between the dimensions of music preferences and personality traits, with the energetic music standing out in extraversion and neuroticism on rebel. We did not get significant results among the types of music and emotions. Conclusions: The results should be viewed under test and has introductory , however following the reported in the literature both in terms of preferences by age, sex and education level , both in terms of the context in which it is heard, still follows music preference dimensions and personality traits .

Estereopsia define-se como a perceção de profundidade baseada na disparidade retiniana. A estereopsia global depende do processamento de estímulos de pontos aleatórios e a estereopsia local depende da perceção de contornos. O objetivo deste estudo é correlacionar três testes de estereopsia: TNO®, StereoTAB® e Fly Stereo Acuity Test® e verificar a sensibilidade e correlação entre eles, tendo o TNO® como gold standard. Incluíram-se 49 estudantes da Escola Superior de Tecnologia da Saúde de Lisboa (ESTeSL) entre os 18 e 26 anos. As variáveis ponto próximo de convergência (ppc), vergências, sintomatologia e correção ótica foram correlacionadas com os três testes. Os valores médios (desvios-padrão) de estereopsia foram: TNO® = 87,04’’ ±84,09’’; FlyTest® = 38,18’’ ±34,59’’; StereoTAB® = 124,89’’ ±137,38’’. Coeficiente de determinação: TNO® e StereoTAB® com R2=0,6 e TNO® e FlyTest® com R2=0,2. O coeficiente de correlação de Pearson mostra uma correlação positiva de entre o TNO® e o StereoTAB® (r=0,784 com α=0,01). O coeficiente de associação de Phi mostrou uma relação positiva forte entre o TNO® e StereoTAB® (Φ=0,848 com α=0,01). Na curva ROC, o StereoTAB® possui uma área sob a curva maior que o FlyTest®, apresentando valor de sensibilidade de 92,3% para uma especificidade de 94,4%, tornando-o num teste sensível e com bom poder discriminativo.
