The aim of this study was to investigate the reliability and validity of the computer based application of the Secret Agent (SA) task of risk-taking and moral decision-making. The participants were 100 male patients in a maximum security hospital (50 with severe mental illness and 50 with personality disorder) and 50 community based healthy controls. All participants completed the SA task, the Iowa Gambling Task (IGT), and measures of IQ, antisocial personality traits, sensation-seeking, impulsivity and sociomoral reasoning. The SA risk-taking and moral decision-making scales had satisfactory levels of reliability (Cronbach’s alpha). Risk-taking correlated significantly with sensation-seeking across all three participant groups. In contrast, risk-taking only correlated with impulsivity among the severe mental illness group. Moral decision-making correlated with sociomoral reasoning among the personality disorder group. No correlation was found between the SA scores and the IGT score and the IGT did not correlate with sensation-seeking or impulsivity. IQ and antisocial personality traits did not correlate with the SA or IGT scales. The study highlights the importance of context, the nature of the risk-taking task, and ‘problem framing’ of the instructions in their relationship with individual differences.  相似文献

We examine the association between neighborhood socio-economic disadvantage and perceived stress during middle and late adolescence among African American youth (N = 665; 51 % female; M = 15.9 years at baseline). In addition, we explored the ways through which neighborhood stressors interacted with an individual’s intra- and interpersonal resources (e.g., coping, social support and substance use), to affect their perceived stress trajectories during adolescence. First, we tested a neighborhood stressors model and found that youth who lived in neighborhoods with greater socioeconomic disadvantage had higher baseline stress and a steeper increase in stress over time. When we included individual-level risk and promotive factors in the model, however, the effect of neighborhood disadvantage on perceived stress was no longer significant, and the stress trajectory was explained by adolescent substance use, social support and perceptions of the neighborhood. Our results support theories of stress and coping, and the importance of proximal intra- and interpersonal factors in either amplifying or mitigating perceptions of stress. We discuss implications of the neighborhood context and how our findings may inform future prevention and intervention related to adolescent stress and development.  相似文献

This study assessed the unique associations of risk perceptions and worry with attitudes about genetic testing for breast cancer susceptibility. Women (general practitioner clinic attenders, university students, and first-degree relatives of breast cancer survivors; N?=?303) read information about genetic testing and completed measures assessing perceived cancer risk, cancer worry, and genetic testing attitudes and beliefs. Worry was associated with greater interest in genetic testing, stronger beliefs that testing has detrimental emotional consequences, and positive beliefs about benefits of testing and risk-reducing surgeries. Perceived risk was unrelated to interest and associated with more skeptical beliefs about emotional consequences and benefits of testing and risk-reducing surgeries. At low worry levels, testing interest increased with more positive beliefs about testing benefits; at high worry levels, interest was high regardless of benefits beliefs. The findings support Leventhal's Common-Sense Model of self-regulation delineating interactive influences of risk-related cognitions and emotions on information processing and behavior.  相似文献

Many women may be reluctant to perform breast self-examination (B.S.E.) regularly due to motivational or self-regulatory deficits. The Health Action Process Approach (Schwarzer, R. (1992). Self-efficacy in the adoption and maintenance of health behaviors: theoretical approaches and a new model. In: Schwarzer, R. (Ed.), Self-efficacy: Thought Control of Action , pp. 217-243. Hemisphere, Washington DC; Schwarzer, R. (2001). Social-cognitive factors in changing health-related behavior. Current Directions in Psychological Science , 10 , 47-51.), a health behavior change model that advocates the separation of motivation and action phases, such as goal setting and goal pursuit, was applied to data from 418 young women whose risk perceptions, outcome expectancies, self-efficacy, intention to perform B.S.E., planning, and reported examination behaviors were examined at two points in time. Risk perception was found to have a negligible influence in a path analysis, whereas self-efficacy emerged as the best predictor of intention and planning. Planning, in turn, appeared to be the best predictor of B.S.E. behaviors, followed by self-efficacy. The results point to the influential role that self-regulatory strategies (such as planning) play in translating goals into action. The study contributes to the current debate on stage theories of health behavior change and the orchestration of self-beliefs and strategies in the context of goal-directed behaviors.  相似文献

Pressure for ‘positive thinking’ (PT; i.e. focusing on positive thoughts/suppressing negative thoughts to ‘fight’ cancer) burdens cancer patients facing health deterioration. It was determined whether PT exposure enhanced effort, control and responsibility attributions assigned to an individual for his/her cancer trajectory. Within an online blog a hypothetical same-gender person describes a personal cancer experience. 482 participants were assigned to one of six experimental conditions in which we manipulated PT exposure (blogger learns about ‘power of PT’ but does not try it, blogger tries PT, control/no PT) and cancer outcome (successful/unsuccessful treatment). A 3?×?2?×?2 multivariate analysis of covariance (with personal cancer experience covariates) tested PT exposure?×?cancer outcome?×?gender effects on attributions for the blogger's cancer outcome. Results indicate that PT exposure enhanced effort and responsibility attributions assigned to individuals for their cancer outcomes and that responsibility attributions differed as a function of gender. Findings suggest that exposure to the idea of PT may lead to cancer patients being perceived as culpable if they do not recover from the disease.  相似文献

Psychosocial correlates of alexithymia were examined in 102 healthy, older adults (ages 53-83; 76% male). Alexithymic ( n = 26) and non-alexithymic ( n = 30) groups, defined by top ( S 70) and bottom ( h 54) quartiles of the distribution of Toronto Alexithymia Scale (26-item) scores, were compared with respect to psychosocial, psychophysiological, and biomedical risk factors for cardiovascular disease. Both categorical ratings and continuous scores of alexithymia were associated with significantly greater levels of trait anxiety, anger-in, neuroticism, hostility, perceived stress, depression, and lower levels of social support. Compared to non-alexithymics, alexithymics displayed significantly greater blood pressure responses to anger provocation and tended to have a greater percent body fat. The groups did not differ in resting cardiovascular parameters, heart rate reactivity, fasting glucose and lipoprotein lipids, body mass index, waist-to-hip ratio, social desirability, or trait anger. These findings suggest several psychosocial and psychophysiological pathways by which alexithymia may confer risk for cardiovascular disease among older adults.  相似文献

Variation in the levels of distress in women at increased risk of breast cancer has been reported, yet there is limited understanding of the factors that are associated with heightened distress in this population. This study took a theoretical approach using Leventhal's Self Regulatory Model (SRM) to understand variation in distress levels. The study examined the associations between perceptions of breast cancer and distress in women at increased risk of breast cancer, and a comparison sample with no experience of the disease in their social environment. Questionnaire data from 117 women at increased risk of breast cancer and 100 comparison women were analysed. Women at increased risk of breast cancer showed comparable levels of general distress but significantly higher levels of cancer specific distress than the comparison group. There were few differences in illness perceptions between the samples, although a number of cognitive perceptions of breast cancer were related to both general and cancer specific distress in the increased risk sample, but not in the comparison sample. The results suggest that the SRM provides a useful framework to explore the psychological response to genetic risk. Further research is required in this population to examine illness perceptions in more detail, validate quantitative measures of illness perceptions, and examine interactions between risk perception and the SRM constructs.  相似文献

When Klein, W. M. gave participants absolute and comparative risk information (crossed experimentally) they were more disturbed by being above than below average, but not by being at higher rather than lower risk. The current experiment tests whether Klein's findings extend to situations involving lower risk figures more typical of genuine health risks, assesses participants’ understanding of the information, and directly compares responses of US and UK samples. Participants were presented with hypothetical information about comparative and absolute risks of deep vein thrombosis. There was a main effect of absolute risk information on disturbance and precaution intentions in the US sample, but no effects of comparative information on these measures in either sample. Understanding was poor among participants receiving both pieces of risk information. Future studies should include measures of understanding to establish whether people are failing to understand what they are told or failing to respond systematically to what they understand. Practically, the findings caution against providing comparative risk information when communicating low risk figures.  相似文献

Reward-related processes are impaired in children with ADHD. Whether these deficits can be ascribed to an aversion to delay or to an altered responsiveness to magnitude, frequency, valence, or the probability of rewards still needs to be explored. In the present study, children with ADHD and normal controls aged 7 to 10 years performed a simple probabilistic discounting task. They had to choose between alternatives where the magnitude of rewards was inversely related to the probability of outcomes. As a result, children with ADHD opted more frequently for less likely but larger rewards than normal controls. Shifts of the response category after positive or negative feedback, however, occurred as often in children with ADHD as in control children. In children with ADHD, the frequency of risky choices was correlated with neuropsychological measures of response time variability but unrelated to measures of inhibitory control. It is concluded that the tendency to select less likely but larger rewards possibly represents a separate facet of dysfunctional reward processing, independent of delay aversion or altered responsiveness to feedback.  相似文献
