There is a vast literature confirming that reactions to different risks are strongly affected by characteristics other than scientific risk estimates; most of this research has concentrated on mapping people's representations of sets of widely varying dangers (e.g. diseases, natural disasters, accidents). This study explored a potentially vital component of risk that cannot be studied by eliciting general reactions to many hazards: the extent to which who is at risk contributes to perceptions and judgments of a risk. While it may be preferable to assume that misfortunes affect the population uniformly, of course the truth is not so egalitarian. Thus, for both theoretical and policy reasons, it is worth exploring psychometrically representations of a particular risk as it affects different people. Using multidimensional scaling and hierarchical cluster analysis, we constructed models of respondents' representations of a disease assumed to be particularly affected by victim perception: Human Immunodeficiency Virus (HIV). Subjects rated the similarity of all possible pairs among 16 scenarios involving HIV infection; the scenarios contained information about both the victim and the method of contraction. A set of attribute scales as well as political/demographic information allowed us both to interpret the structures and to predict individual differences. The results confirmed that reactions to HIV infection are greatly affected by reactions to the victim. In particular, the perceived distastefulness and riskiness of the method of infection loomed larger than did either the overall likability of the victim or the general riskiness of the victim's behavior. Further, the salience of the most statistically influential dimension, ‘deservedness’, depended significantly on demographic and political characteristics of the respondents, suggesting that the relationship between personal values and risk perception is in part mediated by victim perception. Implications for risk perception work and public policy are discussed. 相似文献

An erroneous response is not always accompanied by the conscious perception of the error being made. We examined whether increased response interference on a manual task improved the conscious perception of erroneous eye movements on a concurrent oculomotor task. In the first experiment, we examined whether a correlate of response interference, increased task difficulty alone, could improve perception of errors. We found no effect of task difficulty on self-monitoring. Results from a second experiment suggested that participants’ ability to monitor their eye movements improved with increased response interference, but post hoc analyses indicated that this was due to a decrease in corrective behaviors. Experiment 3 required participants to report directly on whether they had made an eye movement error, and we found that response interference perturbed, rather than improved, participants’ ability to report on their errors. Together, these findings contribute to models of error monitoring, revealing little support for the view that general increases in response interference or task difficulty are signals that contribute to the conscious detection of errors. 相似文献

Testing Structural Models of DSM-IV Symptoms of Common Forms of Child and Adolescent Psychopathology
Lahey BB Rathouz PJ Van Hulle C Urbano RC Krueger RF Applegate B Garriock HA Chapman DA Waldman ID 《Journal of abnormal child psychology》2008,36(2):187-206
Confirmatory factor analyses were conducted of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) symptoms of common mental disorders derived from structured interviews of a representative sample
of 4,049 twin children and adolescents and their adult caretakers. A dimensional model based on the assignment of symptoms
to syndromes in DSM-IV fit better than alternative models, but some dimensions were highly correlated. Modest sex and age
differences in factor loadings and correlations were found that suggest that the dimensions of psychopathology are stable
across sex and age, but slightly more differentiated at older ages and in males. The dimensions of symptoms were found to
be hierarchically organized within higher-order “externalizing” and “internalizing” dimensions, which accounted for much of
their variance. Major depression and generalized anxiety disorder were substantially correlated with both the “externalizing”
dimension and the “internalizing” dimension, however, suggesting the need to reconceptualize the nature of these higher-order
dimensions. 相似文献

Binge eating is a negative indicator of post-surgical weight loss and health outcome in bariatric surgery patients (Hsu, Bentancourt, Sullivan, 1996). Cognitive-behavioral techniques and mindfulness-based practices have been shown to successfully treat binge eating (Agras, Telch, Arnow, Eldredge, & Marnell, 1997; Kristeller & Hallett, 1999). This report describes the development and implementation of a 10-week cognitive-behavioral mindfulness-based group intervention designed to reduce binge eating and address the specific needs of bariatric surgery patients. Posttreatment data showed improvement in binge eating symptoms, depressive symptomatology, and emotion regulation skills and increased motivation to change maladaptive eating behavior. 相似文献

Meta-analyses support the effectiveness of behavioral interventions for the treatment of insomnia, although few have systematically evaluated the relative efficacy of different treatment modalities or the relation of old age to sleep outcomes. In this meta-analysis of randomized controlled trials (k = 23), moderate to large effects of behavioral treatments on subjective sleep outcomes were found. Evaluation of the moderating effects of behavioral intervention type (i.e., cognitive-behavioral treatment, relaxation, behavioral only) revealed similar effects for the 3 treatment modalities. Both middle-aged adults and persons older than 55 years of age showed similar robust improvements in sleep quality, sleep latency, and wakening after sleep onset. A research agenda is recommended to examine the mechanisms of action of behavioral treatments on sleep with increased attention to the high prevalence of insomnia in older individuals. 相似文献

Evaluated an experimental preventive intervention developed for children who perceived their parents as problem drinkers.
The 8-session program was designed to improve children's coping, self-esteem, and social competence, and modify alcohol expectancies
which were specified as mediators of the effects of parental alcohol abuse on child mental health. Participants were 271 self-selected
4th-, 5th-, and 6th-grade students in 13 schools. The children were randomly assigned to treatment or delayed treatment conditions
and the program was given to three successive cohorts of students. A meta-analysis across three different cohorts indicated
significant program effects to improve knowledge of the program content and the use of support- and emotion-focused coping
behaviors for the full sample. A slightly stronger range of effects was found for a high-risk subsample.
