Australian Aboriginal and Torres Strait Islanders are overrepresented in both the prevalence and incidence of the hepatitis C (HCV). HCV knowledge has been associated with a range of positive health behaviours. HCV knowledge has previously been investigated as a single construct; however examining different knowledge domains (i.e. transmission, risk of complications, testing and treatment) separately may be beneficial. This study investigated whether having greater HCV knowledge in different domains is associated with self-reported positive health behaviours. 203 Aboriginal people living with HCV completed a survey assessing HCV knowledge, testing and care, lifestyle changes since diagnosis and treatment intent. Respondents’ knowledge was relatively high. Greater knowledge of risk of health complications was associated with undertaking more positive lifestyle changes since diagnosis. Respondents testing and treatment knowledge was significantly associated with incarceration, lifestyle changes since diagnosis and future treatment intentions. This study illustrates the importance of ensuring that knowledge is high across different HCV domains to optimise a range of positive health behaviours of Aboriginal people living with HCV. Future health promotion campaigns targeted at Aboriginal people living with HCV could benefit from broadening their focus from prevention to other domains such as testing and treatment. 相似文献

This study proposes and tests a new model that seeks to explain associations between religion, spirituality and health outcomes among adolescents. Specifically, we test for mediating effects of perceived spirituality on religion–health relations. Using data from the 4-H Study of Positive Youth Development, we find that perceived spirituality mediates religion–health relations, but that varies based on youths’ conceptualisation of spirituality. With findings confirming that perceived spirituality potentially promote youths’ psychosocial health, we offer some future research directions and implications regarding relations between youths’ spirituality, religion and health behaviours. 相似文献

The current study used a novel problem‐solving task in which the solution could only be reached via interactions between members of dyads. The study aimed to systematically examine how nonverbal interactive behaviour was related to the cultural background of the dyads, the participant's role in the dyad (viz., instructor, problem solver) and task repetition. Twenty‐one Australian dyads and 32 Chinese dyads performed the dyadic puzzle‐solving task while their interactions were video‐recorded. In each dyad, one instructor and one problem solver worked together to solve a seven‐piece puzzle. Six trials, each comprising a different puzzle, were completed. Results indicate that the Australian instructors engaged in significantly more eye gazing and displayed more hand gestures but smiled less than the Chinese instructors. The Australian problem solvers maintained longer eye gazing, displayed more hand gestures and more echoing than their Chinese counterparts. Over trials, the Chinese instructors reduced their total talking time, hand gestures, nodding behaviour and smiling during self‐talking more than the Australian instructors. Moreover, the problem solvers in the dyads from both countries significantly reduced their smiling across trials. The current study shows that nonverbal behaviours during dyadic interactions are related to one's cultural background, role in the task and task repetition. 相似文献

With 21,000 people annually killed in road traffic (estimated figure by World Health Organization), Bangladesh has one of the highest fatality rates in the world. Vulnerable road users (VRUs) account for over 50% of road traffic casualties, and 70% of casualties occur in rural areas. As in many Low and Middle Income Countries (LMICs), the official road accident statistics are incomplete and biased.Safe Crossings (Netherlands) and the Centre for Injury Prevention and Research Bangladesh (CIPRB) (Bangladesh) received permission from the Bangladesh government in 2014 to design and implement an integrated speed management program (consisting of a combination of small-scale infrastructural measures, active community involvement and road user education) at three locations where a national highway intersects small communities. The infrastructural countermeasures to improve road safety consisted of speed humps, rumble strips, signs and road markings and were designed following the Dutch road design guidelines. In a Before–After study design, we used a combination of three research methods to monitor and evaluate the road safety interventions. We created our own traffic accident recording system with trained local record keepers, we conducted laser-gun speed measurements of motorized traffic (both at intervention and control locations), and we applied the Dutch Objective Conflict Technique for Operation and Research (DOCTOR) for observing serious traffic conflicts at the intervention locations. The latter was based upon DOCTOR scores from video recordings of the behaviour at the three experimental locations Before and After the interventions.Prior to installing the intervention program, the three locations combined had, on average, about 100 serious accidents, 10 deaths, and 200 injured people on a yearly basis. In April 2015, all infrastructural measures were completed. In the after period (till the end of January 2016), the alternative accident recording system showed a 66% reduction in the number of serious accidents, a 73% reduction in the number of injured people, and a 67% reduction in the number of people killed.The unobtrusive laser-gun speed measurements resulted in a net reduction of 13.3 km/h (or 20% in relative terms) on average at the intervention locations by taking the general speed development at the control locations into account. According to Nilsson’s power law this would result in a 59% reduction of the number of people killed, well in line with the actual accident figures.The total number of serious conflicts (only DOCTOR scores 3, 4, and 5) was significantly reduced from 64 serious conflicts per location in a 4.5 h period Before to 29 serious conflicts in the After period, on average (Poisson distributed variable, p < 0.01), or a 55% reduction in relative terms. By including the traffic volumes, the reduction in conflict risk overall is 54%. Moreover, the severity of conflicts was reduced in the After period with only one most severe conflict (DOCTOR score 5) left. Buses represent the largest portion of road users involved in serious conflicts at all three locations, followed by cars and CNGs (Compressed Natural Gas vehicle). By far, the most frequently occurring conflict is of the type head-on conflict between an overtaking bus or car that is encountering a road user in opposite direction (for the greater part a CNG).All three evaluation measures point to a similar impact of the intervention program and unveil an improvement in road safety between 54% and 60%. The speed-reducing measures indeed considerably reduce the speed of motorized traffic, both the mean speed and 85th percentile values, both the number and severity of serious conflicts are reduced, and the actual number of accidents has decreased. It appears that Nilsson’s power law for the relation between a difference in mean speed and the change in the number of accidents also applies to LMICs.Speed management measures as common in high-income countries appear to be also effective in LMICs. For evaluation purposes of road safety impacts, a Traffic Conflicts Technique approach (also developed in high-income countries) seems valid and effective as well for application in LMICs.As there are thousands of traffic black spots with similar characteristics as the three intervention locations in Bangladesh, this integrated approach may well offer similar road safety improvements elsewhere. 相似文献

Semi-controlled studies provide a hybrid approach in between controlled experiments and naturalistic driving studies. As in controlled experiments, the researcher can assign participants to groups, select the route and define the tasks, but the participants are given more freedom when it comes to if, when, where and how to perform the tasks. Increased flexibility makes it possible to investigate how drivers use tactical behaviour to accommodate task execution. The disadvantage is decreased control and more complicated analyses. The main objective of this paper is to discuss how to analyse data obtained in semi-controlled studies.The analysis of data from a semi-controlled study include three types of variables: (i) variables that describe the experimental design, (ii) variables that describe the tactical choices of the participants and (iii), operational variables such as speed, lateral position or glance behaviour. To analyse the three types of variables a two-step procedure is suggested. First, the tactical indicators are analysed with regard to the experimental design. Second, the operational indicators are analysed and the tactical indicators are used to divide participants into sub-populations. The semi-controlled design does not need any new statistical procedures to be developed. It is more important that the analysis conditions on the initial properties and not on structures that happen to occur during the experiment, like where the participant chose to do a certain task.We recommend to use the semi-controlled study method when investigating questions involving adaptive and compensatory behaviour on the tactical level. It is especially useful if causal relationships are of interest, if the data collection should be accelerated in comparison to naturalistic studies, and if certain geographical locations definitely should be included. 相似文献

BackgroundRisky driving is considered a key predictive factor in road traffic accidents resulting in morbidity and mortality. Intra-individual emotional and personality factors have been shown to influence risk-taking behaviours among drivers. Despite this, there is limited research investigating the individual dimensions of these constructs and their relationship to risky driving behaviour (RDB). The current study therefore aimed to assess whether the individual dimensions of Emotional Intelligence (EI) were implicated in RDB.MethodsThe sample comprised 179 adults (55% male) aged between 18 and 64 years (M = 29.85, SD = 11.46) and who currently held a valid driver’s licence completed an online survey. Emotional Intelligence was assessed via self-report using the Swinburne University Emotional Intelligence Test (SUEIT), and RDB was measured using both the Brief Distracted Driving Scale (BDDS) and the Dula Dangerous Driving Index (DDDI).ResultsRegression analyses revealed that ‘Risky Driving’ was related to greater levels of Emotional Recognition and Expression and lesser Age [F(6, 172) = 2.27, p < 0.05: R2 = 7.3%], and the Negative Emotions sub-scale of DDDI, was significantly predicted by Emotional Control and Age [F(6, 172) = 6.41, p < 0.05: R2 = 18.3%]. A mediation model incorporating Age, Emotional Control scores and the Negative Emotions driving behaviour score indicated that a significant indirect effect of Age through Emotional Control (K2 = 0.08, 95% CI [−0.02, −0.03]). (H [3] = 10.98, p = 0.012).ConclusionsLower scores on specific indices of EI are associated with increased rates of RDB, suggesting that poor emotional control may impede an individuals’ ability to make safe behavioural decisions when driving. The effect sizes for these models were small, however, and further research is needed to explore the contributory components in this association. Greater awareness of the role of emotional regulation and driving behaviours may be useful in preventing RDB in adults. 相似文献

The aim of this study was to examine health behaviours and happiness and associated factors in low, middle and high income countries. In a cross-sectional survey, 17 508 undergraduate university students (mean age 20.9, SD = 2. 8) from 25 universities in 24 countries across Asia, Africa and the Americas self-completed anonymous questionnaires. Results indicate that the overall happiness mean score among university students across 24 countries was 13.7 (range 4–20). Generally, the study found that university students from countries of the Caribbean, South America and sub-Saharan Africa had greater happiness scores than students from countries in North Africa and Asia. In multivariate linear regression analysis, better subjective socio-economic status, coming from an higher income country, higher social support, higher intrinsic religiosity, higher personal mastery, positive health behaviours (regular breakfast, adequate physical activity, habitual seatbelt use, regular dental check-ups, not having had an injury, not drinking and driving) and negative health behaviours (not having three or more servings of vegetables and eating red meat daily) were correlated with happiness. Improvement to the happiness of university students should consider regional differences in socio-economic environment. 相似文献

ObjectivesThe aim of this study was to obtain a heritability estimate of exercise behaviour in twins and to examine the genetic and environmental contributions to phenotypic associations between personality and exercise behaviour.DesignTwin study was used, the sample including 339 twin pairs (105 MZ and 234 DZ), between 15 and 22 years of age (M = 18.6, SD = 2.31).MethodThe participants filled in a NEO-FFI personality inventory and answered two questions about the frequency (FPE) and intensity (IPE) of physical exercise. We also calculated the composite physical exercise score (CS) representing a combination of FPE and IPE items.ResultsThe broad heritability estimates of three physical exercise variables (FPE, IPE, CS) were significant, with results in the 0.55 to 0.69 range. We found significant phenotypic associations with neuroticism and extraversion. Contrary to our expectations, correlations with conscientiousness were not significant. People scoring higher on extraversion and lower on neuroticism reported exercising more often and more intensely. Phenotypic association between personality traits and physical exercise variables were due to overlapping genetic influences.ConclusionsOur results indicate that the genetic factors contributing to an active lifestyle overlap with those contributing to personality traits extraversion and neuroticism, in line with the “nature” hypothesis which infers the presence of biological differences in predisposition for regular physical activity. 相似文献

Researchers have argued for more dynamic and contextually relevant measures of regulatory processes in interpersonal interactions. In response, we introduce and examine the effectiveness of a new task, the Parent–Child Challenge Task, designed to assess the self‐regulation and coregulation of affect, goal‐directed behaviour, and physiology in parents and their preschoolers in response to an experimental perturbation. Concurrent and predictive validity was examined via relations with children's externalizing behaviours. Mothers used only their words to guide their 3‐year‐old children to complete increasingly difficult puzzles in order to win a prize (N = 96). A challenge condition was initiated midway through the task with a newly introduced time limit. The challenge produced decreases in parental teaching and dyadic behavioural variability and increases in child negative affect and dyadic affective variability, measured by dynamic systems‐based methods. Children rated lower on externalizing showed respiratory sinus arrhythmia (RSA) suppression in response to challenge, whereas those rated higher on externalizing showed RSA augmentation. Additionally, select task changes in affect, behaviour, and physiology predicted teacher‐rated externalizing behaviours four months later. Findings indicate that the Parent–Child Challenge Task was effective in producing regulatory changes and suggest its utility in assessing biobehavioural self‐regulation and coregulation in parents and their preschoolers.
