Personality, state-trait anxiety and admission to university in preuniversity students / Personalidad, ansiedad estado-rasgo e ingreso a la universidad en alumnos preuniversitariosNiño de Guzmán, Isabel, Calderón, Arturo, Escalante, Marisa, Lira, Tula, Morote, Roxana, Ruda Santolaria, María Lourdes 25 September 2017 (has links)
This correlational study identifies personality dimensions, type of anxiety and sociodemographic characteristics of students from a preuniversity center. 1t was conducted with 318 participants of both sexes (43.8% female and 56.2% male) whose ages range from 15 to 19 years old. They were assessed with the following instruments: Costa and McCrae's Persona1ity lnventory NEO PI-R (1992), Spielberger's State-Trait Anxiety lnventory (STAI, 1975) and tutors' reports. Results confirm the presence of a basic factor structure of five dimensions: Likewise, they also reveal significant correlations among Intellectual Quotient (IQ). personality characteristics related to Conscientiousness factor and admission to university. Self-discipline stands out among the facets that correlate with admission. Finally, results are discussed. / Estudio correlacional que identifica las dimensiones de personalidad, el tipo de ansiedad y las características sociodemográficas de alumnos de un centro preuniversitario. Se trabajó con 318 participantes de ambos sexos (43.8% mujeres y 56.2% hombres), que entre 16 y 19 años. Se los evaluó con los siguientes instrumentos: (a) NEO PI-R de Costa y McCrae (1992), (b) Inventario de Ansiedad Estado-Rasgo de Spielberger (IDARE, 1975) y (c) reporte de los tutores. Los resultados confirman la presencia de una estructura factorial básica de cinco dimensiones. Asimismo, revelan correlaciones significativas entre el C.I., características de personalidad asociadas al factor conciencia e ingreso a la universidad. Entre las facetas que correlacionan con el ingreso destaca la autodisciplina. Finalmente, se discuten los resultados.

Časová perspektiva a úzkost / Time perspective and anxietyChvojková, Iveta January 2021 (has links)
This thesis deals with the concept of time perspective with relation to anxiety. In the theoretical part, the terms of state anxiety, trait anxiety and anxiety disorders are defined. Furthermore, a space is dedicated to self-regulatory mechanisms. To give a holistic view, possible positives and benefits of anxiety in general are outlined as well. Moreover, the concept of time perspective, approaches to its measurement and linkage to experience and behaviour of individuals are presented. Subsequently, relationships between anxiety and time perspective are discussed. Last chapter of the theoretical part focuses on possible time perspective interventions for anxious individuals. The empirical part aims at discovering relationships between the concept of time perspective and state anxiety. For this purpose, the data obtained were analysed using a questionnaire survey conducted on a sample of respondents aged in early and middle adulthood. The questionnaire battery consisted of a section gathering demographic information, STAI questionnaire measuring both state and trait anxiety and a shortened version of the ZTPI - short extended by negative future perspective. The results of our research showed a significant positive relationship between anxiety and following time perspectives: negative past and...

[en] EFFECTS OF A BENZODIAZEPINE MIDAZOLAM IN THE ELEVATED PLUS MAZE STRAINS OF RATS WITH HIGH AND LOW LEVELS OF ANXIETY / [pt] EFEITOS DO BENZODIAZEPÍNICO MIDAZOLAM NO LABIRINTO EM CRUZ ELEVADO EM LINHAGENS DE RATOS COM TRAÇOS ALTOS OU BAIXOS DE ANSIEDADEDANIELE RODRIGUES CAVALIERE 29 January 2019 (has links)
[pt] Embora diversos modelos animais sejam utilizados para testar e selecionar efeitos de drogas ansiolíticas e ansiogênicas, relativamente poucos estudos têm examinado os efeitos de manipulações farmacológicas em animais geneticamente selecionados para fenótipos comportamentais mais diretamente relacionados a transtornos específicos de ansiedade em humanos. O presente estudo investigou os efeitos de um benzodiazepínico (midazolam) no labirinto em cruz elevado (LCE) em duas linhagens de ratos que vêm sendo selecionadas em nosso laboratório para traços altos (Cariocas Alto- Congelamento, CAC) ou baixos (Cariocas Baixo-Congelamento, CBC) relacionados à ansiedade. Após terem suas respostas de congelamento ao contexto registradas e comparadas, animais da vigésima quarta, vigésima quinta e vigésima sexta gerações dessas duas linhagens de ratos foram expostos ao labirinto em cruz elevado (LCE) sob os efeitos de injeções intraperitoneais (1,0 ml/kg) de veículo-salina (0,9 por cento) ou midazolam nas doses de 0,25, 0,5, 0,75 e 1,0 mg/kg. Quando injetados com salina, animais CAC e CBC apresentaram parâmetros maiores e menores de ansiedade, respectivamente, em comparação a animais-controle selecionados randomicamente. O midazolam aumentou de maneira semelhante a exploração dos braços abertos em todos os grupos, embora esse efeito ansiolítico nos animais CBC tenha ocorrido apenas na dose mais baixa da droga (0,25 mg/kg). Esses resultados indicam que os traços relacionados à ansiedade previamente selecionados para respostas altas ou baixas de congelamento ao contexto também se expressam fenotipicamente em padrões comportamentais de exploração no LCE. A utilidade dessas duas linhas de ratos para modelar transtorno de ansiedade generalizada e selecionar efeitos potencialmente
ansiolíticos de novas drogas é explorada. / [en] Although several animal models are used to test and screen anxiolytic and anxiogenic-like drug effects, relatively few studies have examined the effects of pharmacological manipulations in genetically selected animals for behavioral phenotypic traits more directly related to specific anxiety disorders in humans. The present study investigated the effects of a benzodiazepine midazolam in the elevated plus-maze (EPM) in two rat lines which have been selectively bred in our laboratory for high (Cariocas High-Freezing, CHF) or
low (Cariocas Low-Freezing, CLF) anxiety-like traits. After being their contextual freezing response registered and compared, animals from the 24th, 25th and 26th generations of these two rat lines were exposed to the EPM under the effects of intraperitoneal injections (1.0 ml/kg) of either vehiclesaline (0.9 per cent) or midazolam in the doses of 0.25, 0.5 and 0.75. When injected with saline, CHF and CLF animals showed higher and lower anxiety-like parameters, respectively, as compared to control-animals randomly selected. Midazolam similarly increased open-arm exploration in all groups, although
this anxiolytic-like effect in CLF animals only occurred at the lowest drug dose (0.25 mg/kg). These results indicate that the anxiety-like traits previously selected for high or low contextual freezing responses are also phenotypically expressed in behavioral patterns of exploration in the EPM. The usefulness of these two rat lines to model generalized anxiety disorder and screen new putative anxiolytic drug effects is explored.
