First-person narratives are becoming a popular means to communicate health risk information. Although studies show they can increase risk perception and motivate health behaviours compared to statistical messages, more research on the conditions in which they are particularly likely to have effects is needed. In this study, we tested a moderator related to how information is processed. Specifically, we hypothesised that thinking in terms of emotions and personal experiences – known as experiential information processing – would increase people’s responsiveness to a narrative. Female college students (N = 138) who reported indoor tanning were randomly assigned to read a first-person narrative message or a statistical message about the risks of skin cancer. Prior to reading the message, the women received instructions that would activate either experiential or rational information processing. Participants then reported their risk perceptions of skin cancer, worry about skin cancer and behaviour intentions related to skin cancer. Analyses showed that message type and information processing interacted to influence risk perceptions and worry. Consistent with hypotheses, participants reported the highest risk perception and worry when they used an experiential information system prior to reading the narrative message. There were no effects on behaviour intentions. Implications of these findings are discussed.  相似文献

It has been suggested that autonomy promotes enhanced reflection on novel information and reduces defensive or biased information processing. This study investigated how autonomy affected people's reactions to known versus novel health-risk information in relation to three behaviours: sun exposure, alcohol consumption and salt intake. Participants (N = 321) completed a measure of autonomy, read either known or novel health-risk information and reported their relative autonomous motivation, attitudes, perceived behavioural control, subjective norm and intentions towards reducing the health-risk behaviour concerned. In line with our hypotheses, the results showed that higher autonomy participants reported greater relative autonomous motivation towards reducing health-risk behaviours than did lower autonomy participants; this effect was mediated by perceptions of the information as less freedom-threatening. The expected interaction between Autonomy and Information Type was not observed. The results indicate that autonomy is associated with greater relative autonomous motivation to engage in health behaviours, and that autonomous motivation may subsequently influence intentions to reduce health-risk behaviour following exposure to health-risk information.  相似文献

Abstract

Ninety-nine participants were assigned to one of three experimental conditions in which they viewed an AIDS education videotape that systematically manipulated whether or not the educator would be perceived as responsible for HIV infection. Participants were administered pre and post-video affect measures, and an HlV/AIDS knowledge test after watching the video. Participants who viewed the speaker who acquired HIV through a blood transfusion (perceived not responsible) and those who viewed the speaker who did not reveal mode of acquisition (control) performed significantly better on the knowledge test compared to those who viewed the speaker who acquired HIV through unprotected sexual inttrcourse (perceived responsible). In addition. male participants in the perceived responsible condition reported a significant increase in sensation-sceking after viewing the video. Finally, females experienced a significantly greater increase in anxiety as a result of seeing the video than did males. Implications of these tindings for the design and implmentation of AIDS education programs were discussed.  相似文献

Abstract

Objectives: The Self-Report Habit Index (SRHI) was originally reported as one-dimensional; however, habit has been described as characterised by several features. Moreover, one-dimensional models for the SRHI have demonstrated poor fit. Therefore, we aimed to compare multidimensional models with a one-dimensional model in both snacking and physical activity habits, besides examining further instrument characteristics.

Design: A cross-sectional study was conducted with high school and university students (n?=?555).

Main outcome measure: The SRHI adapted for physical activity and for snaking habits was applied at one time point.

Results: Nested models with one factor, two factors and three factors were compared. Next, a hierarchical second-order model was tested, and further validity issues, as well as invariance between habits, were examined. Three-dimensional models represented a better fit for both habits. However, fit was still inadequate in the snacking version. In addition, discriminant validity concerns emerged for the physical activity SRHI. Moreover, invariance between the snacking and the physical activity versions was not confirmed.

Conclusions: Considering the SRHI as composed by the dimensions of ‘lack of awareness’, ‘lack of control’ and ‘history of behavioural repetition’ seems to be more accurate. Nevertheless, our findings suggest that further research is needed.  相似文献

The aim of the present study was to examine whether self-affirmation promotes acceptance of threatening type 2 diabetes information and risk-testing behaviour. In an experimental study (N = 84), we manipulated self-affirmation by allowing participants to affirm a value that was either personally important or unimportant to them, and measured participants' risk level prior to reading threatening type 2 diabetes information. As dependent variables, we measured message derogation, intentions to do an online type 2 diabetes risk test and online risk-testing behaviour. Findings showed that self-affirmation decreased message derogation, increased intentions to do an online risk test and promoted online risk test taking among at-risk participants. Among participants not at-risk, self-affirmation decreased intentions and online risk test taking. Therefore, it is concluded, that for an at-risk population self-affirmation can decrease defensive responses to threatening health information and promote (online) risk test taking for diseases.  相似文献

The purpose of this research was to select from the health belief model (HBM), theories of reasoned action (TRA) and planned behaviour (TPB), information–motivation–behavioural skills model (IMB) and social cognitive theory (SCT) the strongest longitudinal predictors of women's condom use and to combine these constructs into a single integrated model of condom use. The integrated model was evaluated for prediction of condom use among young women who had steady versus casual partners. At Time 1, all constructs of the five models and condom use were assessed in an initial and a replication sample (n?=?193, n?=?161). Condom use reassessed 8 weeks later (Time 2) served as the main outcome. Information from IMB, perceived susceptibility, benefits, and barriers from HBM, self-efficacy and self-evaluative expectancies from SCT, and partner norm and attitudes from TPB served as indirect or direct predictors of condom use. All paths replicated across samples. Direct predictors of behaviour varied with relationship status: self-efficacy significantly predicted condom use for women with casual partners, while attitude and partner norm predicted for those with steady partners. Integrated psychosocial models, rich in constructs and relationships drawn from multiple theories of behaviour, may provide a more complete characterisation of health protective behaviour.  相似文献

This study examined the relation between brain activation and cognitive development using event-related brain potentials (ERPs) and a longitudinal design. Five-year-old girls performed a visual recognition (‘oddball’) task and an experimental analogue of the Piagetian conservation of liquid quantity task at three experimental sessions, with one year between consecutive sessions. The data revealed age-related changes in neurocognitive mechanisms common to both tasks. In comparing children before and after a Piagetian transition on a traditional clinical conservation test the data revealed a major shift in performance and ERPs to the experimental analogue of the liquid quantity task. These findings are consistent with a previously performed cross-sectional study and provide strong support for the hypothesis that cognitive transition is related to new neurocognitive mechanisms emerging during childhood. Possible implications of these findings for child neuropsychology are discussed.  相似文献

This study investigated whether fear beliefs can be installed in children after parents had received negatively tinted information about a novel stimulus. Parents of children aged 8-13 years (N = 88) were presented with negative, positive, or ambiguous information about an unknown animal and then given a number of open-ended vignettes describing confrontations with the animal with the instruction to tell their children what would happen in these situations. Results indicated that children's fear beliefs were influenced by the information that was provided to the parent. That is, parents who had received negative information provided more threatening narratives about the animal and hence installed higher levels of fear beliefs in their children than parents who had received positive information. In the case of ambiguous information, the transmission of fear was dependent on parents' trait anxiety levels. More precisely, high trait anxious parents told more negative stories about the unknown animal, which produced higher fear levels in children.  相似文献

The present study examined whether information processing bias against emotional facial expressions is present among individuals with social anxiety. College students with high (high social anxiety group; n  = 26) and low social anxiety (low social anxiety group; n  = 26) performed three different types of working memory tasks: (a) ordering positive and negative facial expressions according to the intensity of emotion; (b) ordering pictures of faces according to age; and (c) ordering geometric shapes according to size. The high social anxiety group performed significantly more poorly than the low social anxiety group on the facial expression task, but not on the other two tasks with the nonemotional stimuli. These results suggest that high social anxiety interferes with processing of emotionally charged facial expressions.  相似文献
