The current study was designed to gain a better understanding of the nature of the relationship between substance use and sexual risk taking within a community sample of women (N = 1,004). Using confirmatory factor analysis, the authors examined the factor structure of sexual risk behaviors and substance use to determine whether they are best conceptualized as domains underlying a single, higher order, risk-taking propensity. A 2 higher order factor model (sexual risk behavior and substance use) provided the best fit to the data, suggesting that these 2 general risk domains are correlated but independent factors. Sensation seeking had large general direct effects on the 2 risk domains and large indirect effects on the 4 first-order factors and the individual indicators. Negative affect had smaller, yet still significant, effects. Impulsivity and anxiety were unrelated to sexual health risk domains.  相似文献

Hindsight bias: An interaction of automatic and motivational factors?   总被引:1,自引:0,他引:1  
If subjects are asked to recollect a former response after having been informed about the correct response, their recollection tends to approach the correct response. This effect has been termedhindsight bias. We studied hindsight bias in an experiment requiring numerical responses to almanac-type questions for physical quantities. We varied (1) the time at which the correct information was provided, (2) the encoding of the original responses by asking/not asking subjects to give a reason for the respective response, and (3) the motivation to recall correctly. We found that hindsight is less biased if reasons are given and if the correct information is provided at an earlier time. Motivation had only interactive effects: (1) With high motivation to recall correctly, the time the correct information was provided had no influence. (2) With reasons given, the variation of motivation showed no effect. These results rule out purely motivational and purely automatic explanations.  相似文献

How is the concept of power integrated into the systemic organismic paradigm? Power concepts, especially Kantor and Lehr's six dimensions of distance regulation mechanisms, are related to several models of family therapy. Power is found to be a part of the Gestalt formation process of Perls, a process of dynamic selfregulation. Each family therapy model is regarded as part of an integrating process. A theory of conflict strategy and of integration strategy in therapy is developed. The article is intended to promote comparison and exploratory discussion around different models of family therapy.  相似文献

The experiment was designed to study the effect of personal control, operationalized in terms of choice between a more demanding and a less demanding task, on persons with different levels of reactivity. Subjects were randomly assigned and individually tested in a 2 (High reactivity/Low reactivity) × 2 (Low rate of stimulus presentation/ High rate of stimulus presentation) × 2 (Choice/No Choice) factorial experiment with 15 subjects per condition. The two principal dependent measures were the total number of correct responses in a serial RT task and the post-task levels of anxiety, anger, and curiosity. The major finding was that while the availability of control had a positive effect on both task performance and affect, its role was situation-specific, i.e. limited to the difficult task. Most probably the availability of control masks the variability of reaction due to individual differences in reactivity. However, high-reactives are still left with the residual stress of unresolved emotions.  相似文献

The present study identified and remediated child-care skill deficits in parents with developmental disabilities to reduce their risk of child neglect. Eleven mothers with developmental disabilities who were considered by social service and child welfare agencies to be providing neglectful child care were found in baseline to have several important child-care skill deficits (e.g., bathing, diaper rash treatment, cleaning baby bottles) compared to nonhandicapped mothers. Parent training (consisting of verbal instructions, pictorial manuals, modeling, feedback, and reinforcement) resulted in rapid acquisition and maintenance of child-care skills in all mothers. Mean percentage correct scores increased from 58% in baseline to 90% in training and 91% in follow-up (M = 31 weeks). The latter two scores compare favorably to the mean score (87%) of 20 nonhandicapped mothers on the same skills. Where observable, parent training was associated with corresponding benefits to the children (e.g., elimination of diaper rash and cradle cap, increased weight gain, successful toilet training). These results indicate that parent training may be a viable option to the removal of the child from the home when parenting skill deficits place the child's well-being in jeopardy.  相似文献
