Dental education programs are known to be highly stressful and stress can affect general health. The aims were to identify sources of stress among preclinical students and to evaluate their perceived levels of stress, self-efficacy and effective coping strategies in a private dental school. One hundred preclinical students in a Turkish private dental school were surveyed using dental environment stress (DES), perceived stress (PSS), general self-efficacy (G-SES) and brief coping scales (Brief-COPE). Age, gender, history of psychiatric treatment, factors that affected the choice of dentistry, choice rank of dental school, scholarship and income was recorded. ‘Exams and grades’ followed by ‘Fear of failing course or year’ were found to be the most stressprovoking factors. The most and the least stressprovoking DES domains were ‘Workload’ and ‘Social stressors’, respectively. ‘Social stressors’ affected male more than female (p < .05). The most and the least common coping strategies were found to be ‘Planning’, and ‘Drug’, respectively. Female used ‘Instrumental support’ more than male (p < .05). Demographic factors had impact on the perceived stress factors and levels, as well as coping strategies. Unlike previous studies establishing high stress levels in dental students, preclinical students displayed moderate level of stress. Clinical dental education might be more responsible for creating stress.  相似文献

Depression and anxiety are hightly prevalent among patients with Type 2 Diabetes (T2D), however not commonly related to outcomes, treatment and comorbidities. Eating behaviors could also have an implication. To evaluate the relation between mood and eating behaviors with demographic, physical, treatment, biochemical profiles and chronic comorbidities in T2D we conducted this exploratory cross sectional study in a population from Mexico. Hospital Anxiety and Depression Scale and the Three Factor Eating Questionnaire Revised 21 (TFEQ-R21) were correlated with age, gender, blood pressure, treatment and comorbidities (nephropathy, neuropathy, retinopathy and cardiopathy). Multi-linear regression models and 2k factorial analyses were conducted. Sixty-one patients (31 male) 55 years old (SD 13) with at least 5 years of T2D were included. Anxiety correlated with depression (r = 0.25, p < 0.05). Gender (women) (std B 0.026, p < 0.001), insulin therapy (std B 0.3, p = 0.11), systolic blood pressure (std B 0.263, p = 0.02) and cardiovascular disease (std B 0.232, p = 0.035) predicted depression. Insulin therapy had a positive effect in cognitive restraint. (std B 0.32, p = 0.001). Age (std B 0.37, p = 0.003) and systolic blood pressure (std B 0.237, p = 0.048) predicted positively emotional eating (not previously published). 2k factorial analyses proved additive interaction between complications and insulin therapy with depression. This study supports the relation between mood disorders and eating behaviors with demographic, physical, treatment, biochemical profiles and chronic comorbidities in T2D and the additive interaction between factors and mood disorders.  相似文献

Are face recognition difficulties in Autism Spectrum Disorders (ASD) related to impaired holistic processing? Gauthier et al. [Gauthier, I., Klaiman, C., &; Schultz, R. T. (2009). Face composite effects reveal abnormal face processing in Autism spectrum disorders. Vision Research, 49, 470–478. doi:10.1016/j.visres.2008.12.007] used the face composite task in adolescents with autism and found a congruency effect that was not modulated by alignment, a result which was interpreted as reflecting qualitatively different face processing mechanisms. In the present study we tested adults with ASD in a composite face task where presentation times were manipulated and further explored whether these participants were sensitive to holistic information in faces using a new version of the composite task: VHFPT 2.0 (The Vanderbilt Holistic Face Processing Test 2.0). Results suggest that adults with ASD process faces holistically and that their facial identity processing abilities are qualitatively similar and as efficient as that of typical adults. The difference between the results of Gauthier et al. (2009) with adolescents and the results with adults here reported are interpreted in terms of a developmental delay.  相似文献

Academic self-handicapping is a very popular subject of research in educational psychology, in which a growing number of related findings are reported. However, apart from a recent meta-analysis (Schwinger et al. in J Educ Psychol 106(3):744–761, 2014), the last comprehensive review of the subject was published 17 years ago (Urdan and Midgley in Educ Psychol Rev 13(2):115–138, 2001). This paper integrates relevant findings accumulated since then, which are discussed in a coherent interpretive framework. The first part of the paper discusses the definition and theoretical grounds of academic self-handicapping, then its manifestations in an academic context are enumerated. The second part of the study focuses on the self-protective function of stereotypes based on self-handicapping as well as on the impressions self-handicapping students may make on others at school. A summary of the contributions of goal orientation theory is provided in relation to self-handicapping, and the effects of various goal orientations and goal structures on academic performance are analysed. Based on an analysis of interactions between self-handicapping and academic performance, the authors argue for the importance of prevention and suggest possible ways to prevent self-handicapping. In conclusion, measurement issues of academic self-handicapping and the methodological paradox inherent in questionnaire measures are discussed.  相似文献

Many studies have linked audiovisual entertainment to hedonia. Recently, also to eudaimonic happiness. The Eudaimonic Spectator Questionnaire is proposed as a new tool to explore eudaimonic motivations that are linked to the consumption of audiovisual entertainment. The new questionnaire groups these eudaimonic motivations into two factors: the cultivation of cognitiveintellectual growth and socialemotional growth. Once the consistency and reliability of the questionnaire was tested, we observed statistically significant differences between fans and non-fan spectators; these differences were observed in both factors. The results indicated that being a fan is associated with the cultivation of human virtues and character strengths.  相似文献

Knowledge about the mechanisms underlying canine vision is far from being exhaustive, especially that concerning post-retinal elaboration. One aspect that has received little attention is motion perception, and in spite of the common belief that dogs are extremely apt at detecting moving stimuli, there is no scientific support for such an assumption. In fact, we recently showed that dogs have higher thresholds than humans for coherent motion detection (Kanizsar et al. in Sci Rep UK 7:11259, 2017). This term refers to the ability of the visual system to perceive several units moving in the same direction, as one coherently moving global unit. Coherent motion perception is commonly investigated using random dot displays, containing variable proportions of coherently moving dots. Here, we investigated the relative contribution of local and global integration mechanisms for coherent motion perception, and changes in detection thresholds as a result of repeated exposure to the experimental stimuli. Dogs who had been involved in the previous study were given a conditioned discrimination task, in which we systematically manipulated dot density and duration and, eventually, re-assessed our subjects’ threshold after extensive exposure to the stimuli. Decreasing dot duration impacted on dogs’ accuracy in detecting coherent motion only at very low duration values, revealing the efficacy of local integration mechanisms. Density impacted on dogs’ accuracy in a linear fashion, indicating less efficient global integration. There was limited evidence of improvement in the re-assessment but, with an average threshold at re-assessment of 29%, dogs’ ability to detect coherent motion remains much poorer than that of humans.  相似文献

Homeownership represents an important indicator of immigrant incorporation and assimilation. This study is a longitudinal analysis of the transition to first-time homeownership among a cohort of youths followed from 1979 to 2009 using the National Longitudinal Survey of Youth (NLSY, 1979). In particular, I examine Mexican generational group differences in the transition to first-time homeownership over an observation period that spans 30 years while evaluating theories of straight-line and segmented assimilation. I find that Mexican homeownership rates do not increase in a linear fashion across generations, relative to native, non-Hispanic whites, even after controlling for various social, demographic, and economic characteristics. Furthermore, analyses limited to Mexicans reveal that first- and second-generation respondents exhibit more success in the transition to first-time homeownership than their third-generation counterparts. Contrary to observing linear gains in homeownership across generations, I find that Mexicans are experiencing segmented paths towards homeownership and achieving upward mobility across generations.  相似文献

Adolescence is characterized by extensive neural development and sensitivity to social context, both of which contribute to engaging in prosocial behaviors. Although it is established that prosocial behaviors are linked to positive outcomes in adulthood, little is known about the neural correlates of adolescents’ prosociality. Identifying whether the brain is differentially responsive to varying types of social input may be important for fostering prosocial behavior. We report pilot results using new stimuli and an ecologically valid donation paradigm indicating (1) brain regions typically recruited during socioemotional processing evinced differential activation when adolescents evaluated prosocial compared with social or noninteractive scenes (N = 20, ages 13–17 years, MAge = 15.30 years), and (2) individual differences in temporoparietal junction recruitment when viewing others’ prosocial behaviors were related to adolescents’ own charitable giving. These novel findings have significant implications for understanding how the adolescent brain processes prosocial acts and for informing ways to support adolescents to engage in prosocial behaviors in their daily lives.  相似文献
