调查娱乐场所服务女性的性行为特征及其安全套使用情况,为预防性病/艾滋病健康教育和政策制定提供参考信息。采用立意抽样方法对我省南昌和萍乡两地娱乐场所服务女性进行问卷调查。娱乐场所服务女性卖淫比例较高,卖淫者安全套使用比例和频率不高,且卖淫者安全套使用存在不平衡现象。必须进一步加大宣传教育力度及强化干预工作。 相似文献

Cognitive-behavioral therapy (CBT) and pharmacotherapy are the most well-established treatments for childhood anxiety disorders. This study examined how parents (N=71) seeking treatment for their child's anxiety disorder perceive the acceptability, believability, and effectiveness of these treatments. While both treatments were perceived favorably, CBT was rated as more acceptable, believable, and effective in the short- and long-term. Children's treatment history influenced parents' perceptions of pharmacotherapy, with parents of children with no treatment history perceiving medication treatment as less acceptable and believable than parents of children with a history of medication alone or in combination with behavior therapy. No effect of treatment history was found for perceptions of CBT. Significant positive correlations emerged between parents' perceived acceptance and believability for pharmacotherapy and child age and level of dysfunction due to their child's anxiety, respectively. The level of the child's anxiety was not significantly correlated with parents' perceptions of either CBT or pharmacotherapy. Our results suggest that parents of anxious children prefer CBT to medication for the treatment of their child's anxiety disorder. Directions for future research are discussed. 相似文献

We evaluated the effects of a behavioral treatment on the safe passing of sharp instruments using the hands-free technique among hospital operating room personnel during surgical procedures. Treatment consisted of participative goal setting, task clarification, and feedback. The average percentage of sharp instruments passed safely increased from 32% to 64% and 31% to 70% between baseline and treatment phases in the inpatient and outpatient surgery units, respectively. Five-month follow-up data suggested maintenance of treatment effects. These findings suggest the utility of organizational behavior management strategies in reducing risky behavior in hospital settings. 相似文献

The results of a functional analysis of problem behavior and a paired-choice assessment were compared to determine whether the same social reinforcers were identified for problem behavior and an appropriate response (time allocation). The two assessments were conducted in classroom settings with 4 adolescents with mental retardation who engaged in severe problem behavior. Each student's classroom teacher served as the therapist for all phases of assessment. The two assessment procedures identified the same social reinforcers for problem and appropriate behavior for 3 of 4 participants. 相似文献

Fear conditioning in posttraumatic stress disorder: evidence for delayed extinction of autonomic, experiential, and behavioural responses 总被引:2,自引:0,他引:2

Aversive conditioning has been proposed as an important factor involved in the etiology of posttraumatic stress disorder (PTSD). However, it is not yet fully understood exactly which learning mechanisms are characteristic for PTSD. PTSD patients (n=36), and healthy individuals with and without trauma exposure (TE group, n=21; nTE group, n=34), underwent a differential fear conditioning experiment consisting of habituation, acquisition, and extinction phases. An electrical stimulus served as the unconditioned stimulus (US), and two neutral pictures as conditioned stimuli (CS+, paired; CS-, unpaired). Conditioned responses were quantified by skin conductance responses (SCRs), subjective ratings of CS valence and US-expectancy, and a behavioural test. In contrast to the nTE group, PTSD patients showed delayed extinction of SCRs to the CS+. Online ratings of valence and US-expectancy as well as the behavioural test confirmed this pattern. These findings point to a deficit in extinction learning and highlight the role of affective valence appraisals and cognitive biases in PTSD. In addition, there was some evidence that a subgroup of PTSD patients had difficulties in learning the CS-US contingency, thereby providing preliminary evidence of reduced discrimination learning. 相似文献

Factors that influence choice between qualitatively different reinforcers (e.g., a food item or a break from work) are important to consider when arranging treatments for problem behavior. Previous findings indicate that children who engage in problem behavior maintained by escape from demands may choose a food item over the functional reinforcer during treatment (DeLeon, Neidert, Anders, & Rodriguez-Catter, 2001; Lalli et al., 1999). However, a number of variables may influence choice between concurrently available forms of reinforcement. An analogue for treatment situations in which positive reinforcement for compliance is in direct competition with negative reinforcement for problem behavior was used in the current study to evaluate several variables that may influence choice. Participants were 5 children who had been diagnosed with developmental disabilities and who engaged in problem behavior maintained by escape from demands. In the first phase, the effects of task preference and schedule of reinforcement on choice between a 30-s break and a high-preference food item were evaluated. The food item was preferred over the break, regardless of the preference level of the task or the reinforcement schedule, for all but 1 participant. In the second phase, the quality of the break was manipulated by combining escape with toys, attention, or both. Only 1 participant showed preference for the enriched break. In the third phase, choice of a medium- or low-preference food item versus the enriched break was evaluated. Three of 4 participants showed preference for the break over the less preferred food item. Results extend previous research by identifying some of the conditions under which individuals who engage in escape-maintained behavior will prefer a food reinforcer over the functional one. 相似文献

The present study investigated emotional influences on behavior in a one-shot, simultaneous, give-some dilemma game. In accordance with functional perspectives on the role of discrete emotions, we found fear to reduce, and guilt to increase levels of cooperation. Moreover, we showed individual differences in the effect of induced emotional states. Specifically, results indicated that inducing fear reduced cooperation only for individuals with a pro-social value orientation, and that guilt induction increased cooperation only for individuals with a pro-self value orientation. We also established that both social value orientations could be adequately described in terms of differences in chronically accessible goals (as assessed by value-importance ratings). These results, therefore, seem to support our hypothesis that individual differences in the behavioral consequences of induced emotional states are related to variation in chronic accessibility of general goals associated with a particular emotional state. 相似文献

This preliminary study compared brief (1 s) and extended (4 s) wait-time on response opportunities, academic responses, accuracy,
and disruptive behavior of two children with challenging behavior during small group instruction. Brief wait-time increased
children’s response opportunities, academic responses, and accuracy in comparison to extended wait-time. Though variable,
brief wait-time also decreased children’s disruptive behavior. Findings differ from previous research, which found performance
improvements with extended wait-time for children with moderate to profound cognitive disabilities. Limitations of the study
and future research suggestions are discussed. 相似文献

既往研究已证实早期经历与个体成年后的行为密切相关,然而早期经历对个体成年后的行为产生长期影响的分子生物机制并不清楚。近年来越来越多的研究表明表观遗传因素在早期经历调控成年个体行为中发挥了重要功能。表观遗传是研究没有DNA序列变化,但是可遗传和可逆转的基因组功能的调控。本文试图从早期经历参与调控个体成年后行为表现以及基因表达的相关表观遗传学修饰进行综述。 相似文献
