In this review, concrete directions are provided for individual risk assessment, treatment planning, and future research on child pornography offending. First, based on reviewing offender characteristics, including demographics, socio-affective difficulties, cognitive distortions and psychosexual issues, it is concluded that despite individual differences, many child pornography offenders have psychological difficulties in multiple areas of functioning. Based on earlier child pornography offender typologies, it is proposed that risk factors of individual offenders can be viewed along the lines of two continua: (1) features related to criminal behavior, and (2) sexual deviance/fantasy. These continua not only give insight into psychological differences between offender types, but also allow for variation in the severity of psychological difficulties within offender types and therefore may enhance individual risk assessment and treatment planning. Moreover, risk factors for cross-over are discussed, including individual characteristics, factors related to engagement with the internet, and the offline environment. Future research should focus on the integration of risk domains within particular offending types. Specifically, research is needed on non-offending pedophiles in order to gain more insight into the relationship between pedophilia and child pornography offending in general.  相似文献

Problematic Internet use has been associated with the neglect of valued activities such as work, exercise, social activities, and relationships. In the present study, we expanded the understanding of problematic Internet use by identifying an important predictor of the inability to curb Internet use despite the desire to do so. Specifically, in a college student sample reporting a mean of 27.8 h of recreational Internet use in the past week, we investigated the role of distress intolerance (DI)—an individual difference variable that refers to the inability of an individual to tolerate emotional discomfort and to engage in goal-directed behavior when distressed—to predict the failure to meet personal restrictions on Internet use. Consistent with hypotheses, DI emerged as a significant predictor of the failure to meet self-control goals in both bivariate and multivariate models, indicating that DI offers unique prediction of self-control failure with problematic Internet use. Given that DI is a modifiable trait, these results encourage consideration of DI-focused early intervention strategies.  相似文献

Tobacco, alcohol, marijuana, and other forms of substance use among children and adolescents is a significant public health concern. At present, one high-risk population of great concern is those affected with Attention-Deficit/Hyperactivity Disorder (ADHD) and those with subthreshold ADHD-like symptoms. The prevalence of tobacco and substance use is considerable within this population, and ADHD and ADHD-like symptoms often present as comorbid conditions. To further the understanding of this problem, a review is provided of youth tobacco and substance use and their biobehavioral influences in the context of ADHD. Using primary care as an example, opportunities for tobacco and substance use prevention and treatment within this high-risk population are examined.  相似文献

Social Consequences of the Internet for Adolescents: A Decade of Research   总被引:2,自引:0,他引:2  
ABSTRACT— Adolescents are currently the defining users of the Internet. They spend more time online than adults do, and they use the Internet for social interaction more often than adults do. This article discusses the state of the literature on the consequences of online communication technologies (e.g., instant messaging) for adolescents' social connectedness and well-being. Whereas several studies in the 1990s suggested that Internet use is detrimental, recent studies tend to report opposite effects. We first explain why the results of more recent studies diverge from those of earlier studies. Then, we discuss a viable hypothesis to explain the recent findings: the Internet-enhanced self-disclosure hypothesis. Finally, we discuss some contingent factors that may deserve special attention in future research.  相似文献

We review the effects of maternal cocaine use on the developing human fetus and infant in terms of methodological problems; the physiological action of cocaine on adults and on the developing fetus; the epidemiology of cocaine use; effects on fetal and infant mortality; growth of cocaine-exposed fetuses and infants; physical anomalies; evidence for and against infant withdrawal from cocaine; neurological effects; behavioral effects as shown by the NBAS; findings related to mother-infant interaction and emotional development; and parenting by cocaine-using mothers. Findings in most areas should be considered preliminary due to methodological problems. Published studies of long-term development are not yet available. In general, deleterious consequences of prenatal cocaine exposure are found for some portion of prenatally exposed infants. However, many findings of no difference are also available in methodologically well-controlled studies.  相似文献

This study examined the relatively long-term effects of repeated exposure to violent and nonviolent pornography on male' laboratory aggression against women. Self-reported likelihood of raping was also assessed as an individual differences variable that might mediate susceptibility to the effects of pornography and to ascertain whether it predicted actual aggressive behavior. Subjects were randomly assigned to the sexually violent, sexually nonviolent, or control exposure conditions. Those assigned to the sexually violent or sexually nonviolent conditions were exposed over a four-week period to ten stimuli including feature-length films and written and pictorial depictions, whereas control subjects were not exposed to any stimuli. About a week following the end of the exposure phase, subjects participated in what they believed to be a totally unrelated experiment in which aggression was assessed within a Buss paradigm. Exposure to the violent or nonviolent pornographic stimuli was not found to affect laboratory aggression. These data are discussed in terms of a recent analysis of media effects emphasizing the temporary activation of ideas in audience' minds. Likelihood of raping ratings was found to predict laboratory aggression.  相似文献

Recent studies with brain magnetic resonance imaging (MRI) have scanned large numbers of children and adolescents repeatedly over time, as their brains develop, tracking volumetric changes in gray and white matter in remarkable detail. Focusing on gray matter changes specifically, here we explain how earlier studies using lobar volumes of specific anatomical regions showed how different lobes of the brain matured at different rates. With the advent of more sophisticated brain mapping methods, it became possible to chart the dynamic trajectory of cortical maturation using detailed 3D and 4D (dynamic) models, showing spreading waves of changes evolving through the cortex. This led to a variety of time-lapse films revealing characteristic deviations from normal development in schizophrenia, bipolar illness, and even in siblings at genetic risk for these disorders. We describe how these methods have helped clarify how cortical development relates to cognitive performance, functional recovery or decline in illness, and ongoing myelination processes. These time-lapse maps have also been used to study effects of genotype and medication on cortical maturation, presenting a powerful framework to study factors that influence the developing brain.  相似文献

By focusing on Internet application initiatives in four places in rural China, this study examines how the Internet is diffused and used in rural settings and what potential it has in helping rural people improve economic conditions and education. The results of this study show that the diffusion and usage of the Internet in rural areas are conditioned by the interplay of structural factors and individual differences. The change agencies have played a dominant role in introducing the Internet to the rural people. One of the major findings of this study is that Internet adoption and usage tend to be closely associated with local farming and business activities. The information needs, conditioned by the modes of production, influence farmers’ information seeking behaviours, which in turn affect adoption inclination and intensive usage.

With the rapid growth of the number of netizens in China, the Internet has become one of the most important parts in the lives of people who not only can get more information on the Internet, but can also express their own views. In other words, the Internet has also become a part of real-world events. Drawing on a case study about ‘The Boycott of Carrefour’ in China during the spring of 2008, the paper first discusses the role and functions of new media during the incident. Through analyses of a story about the culture of labeling others and a conflict between burning a wrong flag in this case, the paper then explores the capriciousness of Chinese cyberspace. The author proposes an explanation on how the illusion of truth is generated on the Internet and then influences the events in the real world. The paper concludes that the Internet is not just a simple technological tool, but it is intertwined with the sociocultural contexts in which it is rooted.

This research examines whether (1) consumers' shopping orientations are significantly related to their preference for shopping online, (2) consumers' demographic characteristics are significantly related to preference for shopping online, (3) relationships of shopping orientation and demographic variables with purchase preferences on the Internet will vary by the type of products (i.e., search, experience, or credence). Deriving from the product classification theory, products are classified into four categories: search products, two types of experience products, and credence products. Data were collected through self-administered surveys from adult population in two metropolitan areas in the Southern United States. The findings significantly support the study's hypotheses that shopping orientations such as convenience and recreational shopper and demographic variables such as gender, education, and household income were significantly related to consumer's online purchase preference. The researchers' findings also confirm that the relationships of shopping orientation and demographic variables with purchase preference for shopping online significantly differ by product category. More specifically, convenience and recreational orientations were positively related to preference for shopping online for experience-1, experience-2, and credence product types, though the directional relationship between recreational shopper orientation and preference for shopping on the Internet was positive rather than negative as hypothesized. The results and discussion section also includes implications drawn from the findings.  相似文献

Administration of psychological questionnaires via the Internet has gained popularity in recent years and touts many advantages. However, before questionnaires that were originally developed as paper-and-pencil measures can be confidently administered over the Internet, it is necessary to document the equivalence of the paper and computer-generated versions [American Psychological Association. (1986). Guidelines for computer-based tests and interpretations. Washington, DC: American Psychological Association; Cohen, R.J., Swerdlik, M.E., & Smith, D.K. (1992). Psychological testing and assessment (2nd ed.). Mountain View, CA: Mayfield Publishing; Cronbach, L.J. (1990). Essentials in psychological testing (5th ed.). New York: Harper Collins; Meier, S. (1994). The chronic crisis in psychological measurement and assessment: A historical survey. San Diego: Academic Press; Schulenberg, S.E., & Yutrzenka, B.A. (2001). Equivalence of computerized and conventional versions of the Beck Depression Inventory- II (BDI-II). Current Psychology: Developmental, Learning, Personality, Social, 20, 216-230]. The current study tested this equivalence for the Obsessive Compulsive Inventory [Foa, E.B., Kozak, M.J., Salkovskis, P.M, Coles, M.E., & Amir, N. (1998). The validation of a new obsessive compulsive disorder scale: The obsessive-compulsive inventory. Psychological Assessment, 10(3), 206-214] and the Obsessive Beliefs Questionnaire-44 [Obsessive Compulsive Cognitions Working Group. (2005). Psychometric validation of the obsessive belief questionnaire and interpretation of intrusions inventory-Part 2: Factor analyses and testing of a brief version. Behaviour Research and Therapy, 43, 1527-1543] in an unselected student sample. Study results support the equivalence of these measures of obsessive compulsive disorder (OCD) symptoms and beliefs independent of administration method (paper versus secure project website). These findings create new opportunities for conducting OCD-related research online.  相似文献

Field, Argyris and Knowles (Behav Res Ther 39 (2001) 1259), and Field, Hamilton, Knowles and Plews (Behav Res Thera 41 (2003) 113) have developed a prospective paradigm for testing Rachman's (Behav Res Ther 15 (1977) 375) proposition that fear information is important in the development of fears and phobias in children. Despite this paradigm being an advance on retrospective reports, the research so far has been restricted to self-reported fear beliefs measured after the information is given. This gives rise to two possible shortcomings: (1) the effects could simply reflect demand characteristics resulting from children conforming to the experimental demands, and (2) although fear information changes beliefs, this might not translate into the behavioural change that would be expected if this information has a powerful effect relevant to the development of pathological fear. This paper describes an experiment that attempts to address these concerns by improving Field et al.'s (2001, 2003) basic paradigm but with the addition of two measures: (1) a behavioural measure of avoidance, and (2) an implicit attitude task that should not be susceptible to deliberate attempts to conform to experimental demands. The result showed that negative and positive information have dramatic, and opposite, effects on self-reported fear beliefs, behavioural avoidance and implicit attitudes. There were no effects of gender on any of these results. This study fully supports Rachman's model and suggests that past work does not merely reflect demand characteristics and that fear information increases behavioural avoidance as well as fear beliefs.  相似文献

The study investigates the hypothesis that children's ability to attribute second-order beliefs facilitates their understanding of evidence, as seen in the ability to distinguish between causes and reasons. Seventy-four children 5–7 yr old were given belief and evidence tests. The belief tests assessed their ability to represent and reason from second-order false-beliefs, and the evidence tests assessed their ability to distinguish between the cause of a situation and a person's reason for believing it. The relation between performance on the two tests was determined, taking into account general language and non-verbal reasoning abilities. Results show that performance on the belief test and on the evidence part of the evidence test improved significantly over the age range, and that a significant proportion of variance in the evidence test scores is accounted for by second-order false-belief understanding, over and above that accounted for by general language and non-verbal abilities. The argument is made that second-order false-belief understanding is fundamental to children's epistemological development, underlying not just their understanding of evidence, but also their understanding of inference and truth.  相似文献

Binge eating disorder (BED) is a common and under-treated condition with major health implications. Cognitive behavioural therapy (CBT) self-help manuals have proved to be efficient in BED treatment. Increasing evidence also support the use of new technology to improve treatment access and dissemination. This is the first randomised controlled study to evaluate the efficacy of an Internet guided self-help treatment programme, based on CBT, for adults with threshold and subthreshold BED. Seventy-four women were randomised into two groups. The first group received the six-month online programme with a six-month follow-up. The second group was placed in a six-month waiting list before participating in the six-month intervention. Guidance consisted of a regular e-mail contact with a coach during the whole intervention. Binge eating behaviour, drive for thinness, body dissatisfaction and interoceptive awareness significantly improved after the Internet self-help treatment intervention. The number of objective binge episodes, overall eating disorder symptoms score and perceived hunger also decreased. Improvements were maintained at six-month follow-up. Dropouts exhibited more shape concern and a higher drive for thinness. Overall, a transfer of CBT-based self-help techniques to the Internet was well accepted by patients, and showed positive results for eating disorders psychopathology.  相似文献

Abstract

In a project that investigated the HIV-related risk behaviour of injecting drug users, respondents were categorized along dimensions of expertness in HIV/AIDS knowledge and knowledge about drug-related health problems. Knowledge about drug-related health problems was found to be significantly associated with sharing. Better informed respondents were less likely to share injecting equipment and to predict they would share in future. They were more likely to adopt consistent injecting hygiene, seek information about AIDS, and perceive themselves as in control of their lives. No significant relationships were observed between sharing and HIV/AIDS knowledge. The data have relevance for AIDS educational strategies, since knowledge about AIDS and HIV transmission appears to be insufficient to induce behavioural change. Greater emphasis on the health problems that afflict most injectors may be a way of encouraging general harm minimization.  相似文献

Discipline of children is a major topic of concern in our society. This paper places discipline in a historical perspective by briefly tracing disciplinary practices from the 1600s to the present day in the United States. Four primary trends are then delineated. These include the following: movement from strict discipline to lax discipline to mixed messages concerning discipline; determinants of discipline changing from Puritan religious beliefs to experts in fields such as psychology; the increasing role of legislative efforts focusing on children's rights; and the changing role of fathers in childrearing in general and discipline in particular. Viewed against such a historical account, implications for mental health professionals in shaping disciplinary practices are offered. These include generating data to provide needed answers and assuming an active role in setting policy.  相似文献

Although religious movements are a powerful force in politics, there has been relatively little work that adequately analyses the relationship between communication technologies and Christian political mobilisation in the United States. In addressing this deficit, this article has three interrelated objectives. First, it traces the impact of media technology on the evangelical project, paying specific attention to radio and television, and argues that these two media have had a largely unifying influence. Second, it seeks a better understanding of the impact of the Internet upon evangelical organisations by reviewing relevant academic literature in the context of on-the-ground developments. In doing so, the authors argue that instead of working to facilitate greater unity among evangelicals, as radio and television did in the past, the Internet is instead fragmenting and polarising them. Third, and more speculatively, they discuss implications for a fragmented evangelical community, and call upon scholars to conduct more research into recent developments in communications technology as it relates to Christian political mobilisation in the United States. Combined, these goals work to illustrate the complex relationship between media, religious organisations, and mass political mobilisation.  相似文献
