Brief planning interventions, usually delivered within paper and pencil questionnaires, have been found to be effective in changing health behaviours. Using a double-blind randomised controlled trial, this study examined the efficacy of two types of planning interventions (action plans and coping plans) in increasing physical activity levels when they are delivered via the internet. Following the completion of self-reported physical activity (primary outcome) and theory of planned behaviour (TPB) measures at baseline, students (N = 1273) were randomised into one of four conditions on the basis of a 2 (received instructions to form action plans or not) × 2 (received instructions to form coping plans or not) factorial design. Physical activity (primary outcome) and TPB measures were completed again at two-month follow-up. An objective measure (attendance at the university's sports facilities) was employed 6 weeks after a follow-up for a duration of 13 weeks (secondary outcome). The interventions did not change self-reported physical activity, attendance at campus sports facilities or TPB measures. This might be due to low adherence to the intervention protocol (ranging from 58.8 to 76.7%). The results of this study suggest that the planning interventions under investigation are ineffective in changing behaviour when delivered online to a sample of participants unaware of the allocation to different conditions. Possible moderators of the effectiveness of planning interventions in changing health behaviours are discussed. 相似文献

One of the major challenges of a knowledge society is that students as well as other citizens must learn to understand and integrate information from multiple textual sources. Still, task and reader characteristics that may facilitate or constrain such intertextual processes are not well understood by researchers. In this study, we compare the effects of summary and argument essay tasks when undergraduates read seven different texts on a particular scientific topic, finding that an instruction to write summaries may lead to better understanding and integration than an instruction to write argument essays. We discuss several possible explanations for this result. We also found that beliefs about the certainty of knowledge in some instances can moderate the effect of task on comprehension performance. 相似文献

This study used think-aloud methodology to explore undergraduates' spontaneous attention to and use of source information while reading six documents that presented conflicting views on a controversial social scientific issue in a Google-like environment. Results showed that students explicitly and implicitly paid attention to sources of documents as well as sources cited within documents and that their attention to source information was associated with its use in evaluating, predicting, and interpreting the content of the documents. Students' sourcing activity varied across documents. The two documents that took the strongest, opposing stances on the controversy elicited the most sourcing. We also observed that, in essays they wrote on the controversy, students' spontaneous sourcing activity was related to their citation of a particularly trustworthy source. The study's theoretical implications are discussed in terms of the Documents Model framework. 相似文献

The aim of the current study was to examine whether the timing of sleep have changed over the last two decades. As part of a general survey of activities throughout the 24-hr. cycle, collected in 1980, 1990, and 2000 by Statistics Norway, information on sleep timing was obtained for every 15-min. interval for 1 wk. All three samples were representative of Norwegians. The age span was from 16 to 74 years. Timing of sleep was significantly delayed in 2000 compared to 1990 and especially so in 1980, but with no change in total amount of sleep. From 1980 to 2000, there was an increasing discrepancy in sleep or wake timing between weekdays and weekends. The current analyses show that people sleep as much as before but do so at different times. The increased discrepancy between weekdays and weekends indicates that overall sleep habits are poorer now than previously. 相似文献

The objective was to compare the effects of two types of written material for insomnia in a randomized trial with follow-up after three months. Insomniacs were recruited through newspaper advertisements to a web-based survey with validated questionnaires about sleep, anxiety, depression, and use of sleep medications. A self-help book focusing on cognitive behavioral therapy for insomnia was compared to standard sleep hygiene advice; 77 and 78 participants were randomized to self-help book or sleep hygiene advice, respectively. The response rate was 81.9%. The self-help book gave significantly better scores on the sleep questionnaires compared to sleep hygiene advice. The proportion using sleep medications was reduced in the self-help book group, whereas it was increased in the sleep hygiene group. Compared to pre-treatment, the self-help book improved scores on the sleep (effect sizes 0.61-0.62) and depression (effect size 0.18) scales, whereas the sleep hygiene advice improved scores on some sleep scales (effect sizes 0.24-0.28), but worsened another (effect size -0.36). In addition, sleep hygiene advice increased the number of days per week where they took sleep medications (effect size -0.50). To conclude, in this randomized controlled trial, the self-help book improved sleep and reduced the proportion using sleep medications compared to sleep hygiene advice. The self-help book is an efficient low-threshold intervention, which is cheap and easily available for patients suffering from insomnia. Sleep hygiene advice also improved sleep at follow-up, but increased sleep medication use. Thus, caution is warranted when sleep hygiene advice are given as a single treatment. 相似文献

Research on probability judgment has traditionally emphasized that people are susceptible to biases because they rely on “variable substitution”: the assessment of normative variables is replaced by assessment of heuristic, subjective variables. A recent proposal is that many of these biases may rather derive from constraints on cognitive integration, where the capacity-limited and sequential nature of controlled judgment promotes linear additive integration, in contrast to many integration rules of probability theory (Juslin, Nilsson, & Winman, 2009). A key implication by this theory is that it should be possible to improve peoples’ probabilistic reasoning by changing probability problems into logarithm formats that require additive rather than multiplicative integration. Three experiments demonstrate that recasting tasks in a way that allows people to arrive at the answers by additive integration decreases cognitive biases, and while people can rapidly learn to produce the correct answers in an additive formats, they have great difficulty doing so with a multiplicative format. 相似文献

This paper reports on the role of personality as an antecedent of proactive behaviour at work in the form of whistleblowing. In the interest of triangulation, two studies were used, along with two personality measures. The results of Study 1, conducted among 503 municipality employees, show that the NEO Five‐Factor Inventory dimensions of extraversion and agreeableness are significantly associated with whistleblowing, with odds ratios of 1.13 and 0.91, respectively. The result from Study 2, conducted among a representative sample of employees, shows that the circumplex of interpersonal problems dimension domineering was significantly associated with whistleblowing, with an odds ratio of 1.66. The results suggest that personality, in the form of high extraversion and dominance and low agreeableness, do play a role as antecedents of whistleblowing. 相似文献

In families with hereditary breast and ovarian cancer, there is limited knowledge about the reactions of BRCA1/2 mutation
positive males. In the present qualitative study, fifteen BRCA1/2 mutation positive men in Norway participated in two successive,
in-depth interviews. Seven female partners participated in the second interview. The men reported strong emotional reactions
to their positive test results, and they expressed a desire to keep the genetic information private. They considered discussing
their test results or health related information with other males as difficult, and they perceived females as their sources
of social and emotional support. Interestingly, the second interview revealed important information not communicated during
the first interview. The findings of this study contribute to the discussion of whether men who test positive for a BRCA1/2
mutation should receive tailored genetic counseling sessions. Health care providers should be aware of psychological vulnerability
in these men, likely stemming from fewer emotional supports in their social networks. 相似文献

Whereas there is extensive documentation that attribute framing influences the content of people’s thought, we generally know less about how it affects the processes assumed to precede those thoughts. While existing explanations for attribute framing effects rely completely on valence-based associative processing, the results obtained in the present study are also consistent with the notion that negative framing stimulates more effortful and thorough information processing than positive framing. Specifically, results from a simulated business decision-making experiment showed that decision makers receiving negatively framed information had significantly better recall than those receiving positively framed information. Furthermore, decision makers in the negative framing condition were less confident than decision makers in the positively framed condition. Finally, compared to a no-framing condition, decision makers receiving positive framing deviated significantly more in evaluation than decision makers receiving negative framing did. 相似文献

A workshop was conducted as part of the International Metropolis Conference held in Vienna, Austria in September 2003. The Metropolis Project is meant to facilitate research in the area of migration that can optimally inform policy. In this context, a workshop was conducted with the objective of discussing how policy-relevant research on discrimination could be conducted internationally. Four broad areas were addressed: ‘key stakeholder’ involvement, obtaining ethical and other forms of approval, international, national and local funding opportunities, and qualitative and quantitative methodology and questionnaire development. Viewpoints represented included those of non-governmental organizations, researchers, health professionals, and policy-makers/implementers. Countries represented in the discussions included Australia, Austria, Canada, Germany, Norway, Sweden, the United Kingdom, and the United States. Key conceptual differences included how best to define discrimination, societal acknowledgement of discrimination, the meaning of ‘race’, ‘racism’, ‘national’, and ‘migrant’, and perceptions of national identity. 相似文献
