Este trabalhou avaliou o stress e a ansiedade em 30 casais, que se submeteram à reprodução assistida no momento anterior à coleta dos óvulos e/ou espermatozóides, tendo um tempo de infertilidade que variou de 1 a 17 anos. Para avaliação da ansiedade foi aplicado o STAI-STATE TRAIT ANXIETY INVENTORY (STAI) e o Stress foi avaliado através do SCOPE-STRESS. No STAI foi acrescentada uma escala visual analógica para medir também a intensidade da ansiedade. A Ficha de Identificação avaliou questões como: idade, sexo, nacionalidade, profissão, ocupação, religião, grau de instrução, renda mensal, estado civil, tempo de casado e questões como: tempo de infertilidade, filhos naturais ou adotivos, profissionais implicados no tratamento, a existência de tentativas anteriores e os momentos de maior tensão emocional nas tentativas anteriores e a atual. Dentre os 36 sujeitos que já haviam feito tentativas anteriores de Reprodução Assistida, um dos três momentos de maior tensão emocional foi o de aguardar a gravidez. Dentre os 60 sujeitos, ou seja, todos os que estão na tentativa atual, aguardar a gravidez foi também um dos três momentos que geraram maior tensão. O diagnóstico de infertilidade foi misto em 33,3% dos casais, apenas feminino em 20% e apenas masculino em 46,7% dos casais. As mulheres apresentaram grau de ansiedade significantemente maior que os homens quanto às escalas Stai-Trait freqüência e intensidade e semelhantes quanto às escalas Stai-State freqüência e intensidade. Não houve diferença significante entre os escores médios dos homens e mulheres quanto às medidas descritivas do Scope-Stress. / This work evaluated stress and anxiety in 30 couples submitted to assisted reproduction, with an infertility period that ranged from 1 to 17 years, the moment just before the oocyte retrieval and/or semen sample. For anxiety evaluation the Stai-State Trait Anxiety Inventory (STAI) was applied, and stress was evaluated using the Scope-Stress. While applying STAI, a visual analogic scale was added to measure the intensity of anxiety. The identification form included information such as: age, gender, nationality, profession, occupation, religion, school level, monthly income, marital status, married time and issues such as: infertility period, existence of natural or adoptive children, professionals involved in infertility treatment, existence of previous attempts and the moments of major emotional stress during the previous attempts and during the present one. Among the 36 subjects submitted to previous attempts of Assisted Reproduction, one of the three moments of major emotional stress was the attendance of pregnancy confirmation. Among the all 60 subjects submitted to the present attempt, attendance of pregnancy confirmation also was one of the three moments of major emotional stress. Infertility diagnosis was mixed in 33,3% of the couples, exclusively feminine in 20% and exclusively masculine in 46,7% of the couples. Women presented a significantly higher anxiety degree than men, regarding the STAI-TRAIT scales of frequency and intensity and similar regarding the STAI-STATE scales of frequency and intensity. There was no significant difference between the mean scores of men and women regarding descriptive measures of the SCOPE-STRESS.

According to Fredrickson's broaden-and-build theory of positive emotions, positive emotions -- such as joy, contentment, and love -- help individuals cope with stress, maintain well-being, and flourish in life. Guided by this theory, this dissertation project conducted three studies which explored the multidimensional influences of positive emotions on stress, coping strategies, resilience, trait anxiety, depressive symptoms, and work engagement. Study 1 examined the mediating role of coping strategies on the link between positive emotions and resilience; in addition, the moderating effect of resilience on the influence of stress toward trait anxiety and depressive symptoms was tested. Study 2 investigated if one's positivity would distinguish differences in their levels of stress, trait anxiety, and depressive symptoms. Finally, Study 3 examined whether stress and positive emotions would account for the variance in work engagement, over and above what has been explained by known predictors -- specifically, work meaningfulness and supervisor support. Path analysis, interaction analysis, multivariate analysis of variance, and hierarchical multiple regression analysis were used to test the different models within these studies. A sample of 200 postdoctoral fellows completed the survey (38% response rate). Results showed that a) coping strategies partially mediated the link between positive emotions and resilience; b) resilience moderated the effect of stress on trait anxiety and depressive symptoms; c) the different categories of positivity distinguished differences in experienced stress, trait anxiety, and depressive symptoms; d) stress and positive emotions accounted for additional variance in work engagement, above what is already explained by work meaningfulness and supervisor support; and e) positive emotions completely mediated the relationship between supervisor support and work engagement. Findings support the broaden-and-build theory's hypotheses that positive emotions enhance adaptive coping strategies and fuel resilience. The data also demonstrated that resilience protected postdocs from experiencing heightened levels of trait anxiety and depressive symptoms by diminishing their relationships with stress. One strategy to optimize health would be to increase opportunities for postdocs to experience positive emotions, which would subsequently spark the upward spiral toward improved coping, greater resilience, and reduced stress, anxiety, and depression. To promote work engagement, it is important for supervisors to not only be mindful of assigning meaningful work to their employees (or help employees find meaning in their work), but supervisors should also be a supportive leader within a positive workplace environment. / text

Approximately 52% of cancer patients require radiation therapy during the progression of their illness. Radiation therapy is a safe procedure; however, errors may occur and have the potential to harm patients. Recent studies have looked at patient engagement as a means of preventing errors in healthcare. Through interviews and focus groups, this study looks at patients’ and radiation therapists’ current perceptions of safety in radiation therapy and whether they feel that patient engagement in the form of a patient-provider collaborative checklist can improve its safety or the perception of safety. Through workflow observations and literature reviews, a patient-provider collaborative checklist was developed. Furthermore, STAI surveys were conducted to document the progression of patient anxiety through treatment. Feedback from radiation therapists demonstrated their opinions on the usability of the final iteration of the patient-provider collaborative checklist and how it could fit into the clinical setting.

Reaction times (RTs) are a valuable measure for assessing cognitive processes. However, RTs are susceptible to confounds and therefore variable. Exposure to threat, for example, speeds up or slows down responses. Distinct task types to some extent account for differential effects of threat on RTs. But also do inter-individual differences like trait anxiety. In this functional magnetic resonance imaging (fMRI) study, we investigated whether activation within the amygdala, a brain region closely linked to the processing of threat, may also function as a predictor of RTs, similar to trait anxiety scores. After threat conditioning by means of aversive electric shocks, 45 participants performed a choice RT task during alternating 30 s blocks in the presence of the threat conditioned stimulus [CS+] or of the safe control stimulus [CS-]. Trait anxiety was assessed with the State-Trait Anxiety Inventory and participants were median split into a high- and a low-anxiety subgroup. We tested three hypotheses: (1) RTs will be faster during the exposure to threat compared to the safe condition in individuals with high trait anxiety. (2) The amygdala fMRI signal will be higher in the threat condition compared to the safe condition. (3) Amygdala fMRI signal prior to a RT trial will be correlated with the corresponding RT. We found that, the high-anxious subgroup showed faster responses in the threat condition compared to the safe condition, while the low-anxious subgroup showed no significant difference in RTs in the threat condition compared to the safe condition. Though the fMRI analysis did not reveal an effect of condition on amygdala activity, we found a trial-by-trial correlation between blood-oxygen-level-dependent signal within the right amygdala prior to the CRT task and the subsequent RT. Taken together, the results of this study showed that exposure to threat modulates task performance. This modulation is influenced by personality trait. Additionally and most importantly, activation in the amygdala predicts behavior in a simple task that is performed during the exposure to threat. This finding is in line with “attentional capture by threat”—a model that includes the amygdala as a key brain region for the process that causes the response slowing.

The psychosocial and cultural predictors of cigarette smoking were examined among a sample of 175 African-American adults. Participants completed a self-report inventory containing the Beck Depression Inventory, the Perceived Stress Scale, the Speilberger State-Trait Anxiety, the African-American Acculturation Scale, and questions regarding their smoking, demographics, and risk-taking tendencies.

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...
