Objective: The study set out to investigate socio-economic, biomedical, health and behavioural and psychological factors in childhood and adulthood associated with the prevalence of asthma in adulthood, drawing data from The National Child Development Studies (NCDS), a birth cohort in the UK.

Design: The National Child Development Study, a nationally representative sample of 17,415 babies born in Great Britain in 1958 and followed up at 7, 11, 33 and 50 years was used.

Main Outcome Measure: The prevalence of asthma at age 50 was the outcome measure. The analytic sample consists of 5118 participants with complete data on a set of measures at birth, at ages 7, 11, 33 and 50 years.

Results: Using logistic regression analyses, results showed that childhood asthma (OR = 6.77: 4.38–10.48, p < .001) and respiratory symptoms (OR = 1.83: 1.18–2.86, p < .01), maternal smoking during pregnancy (OR = 1.26: 1.00–1.59, p < .05), Body and Mass Index (BMI) (OR = 1.03: 1.02–1.05, p < .001), traits Neuroticism (OR = 1.13: 1.01–1.21, p < .05) and Conscientiousness (OR = 0.76: 0.76–0.96, p < .01), as well as sex (OR = 1.49: 1.15–1.94, p < .001) were all significantly associated with the prevalence of asthma in adulthood.

Conclusion: The study shows that both childhood and adulthood psychological and sociological factors are significantly associated with the prevalence of asthma in adulthood, though more work need to be done in this area.  相似文献

Elementary school is as much about developing attitudes as competence. With this fact in mind, the Japanese national government established a plan to enhance elementary school students’ motivation for learning English. The success of this program has, however, not been empirically tested. This study aimed to assess the longitudinal, discrete development of Japanese elementary school students’ motivation for learning English as a foreign language. A cohort of 513 Japanese elementary students participated in the study across 2 years of school. Students responded to surveys regarding the quality of their motivation at three time points, and their engagement at two time points. Latent profile analysis followed by latent profile transition analysis was used to assess the sample for latent subgroups. With subgroups established at three time points, a Mover–Stayer model was tested to estimate the movement of students among the subgroups across three time points and 2 years of elementary school education. Three theoretically consistent latent subgroups were observed at each of the time points. Based on theory and past empirical research, the subgroups (presented from least to most adaptive) were labeled: Poor Quality, High Quantity, and Good Quality. Across the three measurements, an overall shift of students to higher quantity and quality motivational subgroups was observed. This study provides evidence that the low-stakes, high-interest approach currently undertaken may have the desired effect of improving students’ motivation to learn across 2 years of schooling. Implications for both practice and national policy are discussed.  相似文献

The color psychology literature has made a convincing case that color is not just about aesthetics, but also about meaning. This work has involved situational manipulations of color, rendering it uncertain as to whether color‐meaning associations can be used to characterize how people differ from each other. The present research focuses on the idea that the color red is linked to, or associated with, individual differences in interpersonal hostility. Across four studies (N = 376 undergraduates), red preferences and perceptual biases were measured along with individual differences in interpersonal hostility. It was found that (a) a preference for the color red was higher as interpersonal hostility increased, (b) hostile people were biased to see the color red more frequently than nonhostile people, and (c) there was a relationship between a preference for the color red and hostile social decision making. These studies represent an important extension of the color psychology literature, highlighting the need to attend to person‐based, as well as situation‐based, factors.  相似文献

ABSTRACT. Cybernetic theories of self-regulation contend that an individual's goal system may work best to the extent it is differentiated. The present investigation pioneered an assessment of goal differentiation in relation to an important feature of goals—intrinsic motivation—and quantified the extent to which intrinsic motivation systematically increased from low- to mid- to high-level goals, the resulting individual difference termed cybernetic self-determination. In Study 1 (n = 106), it was found that frustrating daily events precipitated motivations to quit at low, but not high, levels of cybernetic self-determination. In Study 2 (n = 111), it was found that negative feedback was associated with reduced goal persistence at low, but not high, levels of cybernetic self-determination. The findings therefore converge on the idea that individual differences in cybernetic self-determination are consequential in buffering reactions to obstacles in daily life. Implications for personality, motivation, and self-regulation literatures are discussed.  相似文献

Prior research has explored how employees’ perceptions of their leaders impact their work attitudes and behaviors. Studies have shown that charismatic leaders motivate individuals to be more engaged and to exhibit more organizational citizenship behaviors. This study considers how a moderator, citizenship pressure, affects how charismatic leaders might inspire their followers to go above and beyond and be more engaged in their work. Using a sample of 243 workers, this study's findings show that charismatic leadership has a stronger positive effect on job engagement when employees perceive less citizenship pressure. Citizenship pressure did not moderate the relationship between charismatic leadership and organizational citizenship behavior. Implications of this study include an examination of the moderating influence of citizenship pressure, a relatively new construct. Practically, the implications may shed some light on leadership factors that encourage increased effort from employees and greater employee engagement. More specifically, findings suggest that persons are motivated to exhibit more OCBs to meet high expectations of charismatic leaders. However, when seeking engagement, feeling pressure to perform these OCBs has a reverse effect as more job engagement results with less citizenship pressure. Future research suggestions and limitations are discussed.  相似文献

Human choice under uncertainty is influenced by erroneous beliefs about randomness. In simple binary choice tasks, such as red/black predictions in roulette, long outcome runs (e.g. red, red, red) typically increase the tendency to predict the other outcome (i.e. black), an effect labeled the “gambler's fallacy.” In these settings, participants may also attend to streaks in their predictive performance. Winning and losing streaks are thought to affect decision confidence, although prior work indicates conflicting directions. Over three laboratory experiments involving red/black predictions in a sequential roulette task, we sought to identify the effects of outcome runs and winning/losing streaks upon color predictions, decision confidence and betting behavior. Experiments 1 (n = 40) and 3 (n = 40) obtained trial‐by‐trial confidence ratings, with a win/no win payoff and a no loss/loss payoff, respectively. Experiment 2 (n = 39) obtained a trial‐by‐trial bet amount on an equivalent scale. In each experiment, the gambler's fallacy was observed on choice behavior after color runs and, in experiment 2, on betting behavior after color runs. Feedback streaks exerted no reliable influence on confidence ratings, in either payoff condition. Betting behavior, on the other hand, increased as a function of losing streaks. The increase in betting on losing streaks is interpreted as a manifestation of loss chasing; these data help clarify the psychological mechanisms underlying loss chasing and caution against the use of betting measures (“post‐decision wagering”) as a straightforward index of decision confidence. © 2014 The Authors.
