Data for 422 methadone treatment clients in the National Treatment Improvement Evaluation Study (NTIES) were analyzed. Clients maintained continuously in methadone treatment for longer than 12 months and clients who leftbetween 3–12 months were compared with clients treated for less than 3 months. Additionally, clients treated for 3–12 months who had short follow-up periods (6-month average) were compared with 3–12-month clients with long follow-up periods (11-month average). Positive treatment outcomes includinglower drug use, reduced risk of viral infectionand sexually transmitted disease (through needle sharing and multiple sex partners), and less criminality wereassociated with both longer duration treatment and shorter follow-up periods. The findings suggested that continuous methadone treatment of 12 or more months is optimal, whereas stays of less than3 months may be ineffective. Furthermore, stays of 3–12 months are likelyto be beneficial over a relatively short time span, for example 6 months.  相似文献

This longitudinal study examined adolescent girls' perception of control over sexually transmitted disease (STD) acquisition. Participants were asked questions regarding their perception of their STD locus of control (internal control; control by parents, partners, peers, and health care providers; and chance) at two waves of data collection. Of the 116 participants (mean age = 17 years), 82% were African-American and 18% were Caucasian. Responses to the measure of locus of control were significantly correlated across a 6-month interval. The responses regarding internal control, control by partner, and chance were not related to the acquisition of an STD in the next 6 months. Further, they were not influenced by an STD in the preceding 6 months. These results indicate that responses to a locus of control measure were stable over a 6-month period, and internal, partner, and chance locus of control perceptions seem to be neither determined by STD experience nor directly related to future STD acquisition. However, understanding an individual's locus of control may be helpful in providing appropriate counseling. Future research could examine how adolescent girls form their perceptions of control over STD acquisition.  相似文献

A new contraceptive technology may advance the science of family planning but may do little to affect health if potential users do not deem it an acceptable method. The authors conducted an acceptability study of a newly developed contraceptive method--personal hormone monitoring. A sample of 480 English volunteers present at the 6th month of a 13-month longitudinal study completed surveys regarding their attitudes toward a personal hormone monitor for the purpose of contraception. The authors used the participants' responses to determine (a) the extent to which the participants accepted the monitor, (b) how their ratings of acceptability changed over time, (c) the extent to which contextual variables predicted changes in acceptability over time, and (d) whether those contextual variables predicted final acceptability of the monitor. Results suggested that no single method of family planning is best for everyone and specified the people for whom personal hormone monitoring may be most suitable.  相似文献

Psychologists and counselors completed a questionnaire devised by the authors to explore the relationships between their extent of endorsement of empathy definitions, their use and views of empathy, and their identification with theories of psychotherapy. Results from 565 respondents suggested that those who identified with humanistic/experiential and psychodynamic theories seemed to have similar views of how empathy is defined and viewed and reported that they use empathy more than those with other theoretical inclinations. These findings suggest that there is some consistency between theoretical identification and definition, as well as reported use and views of empathy.  相似文献

The Oedipus complex is typically thought to begin in the phallic phase, when the child's relationship to the parents as a couple achieves central prominence. In contrast, the author views the appearance of oedipal conflicts in the phallic phase as the end point of a line of development of triangular relatedness that began in infancy. An aspect of the Kleinian view of the oedipal situation--that awareness of the parents as a couple begins in the preoedipal period--deserves serious consideration. A patient is presented for whom the working through of early oedipal issues in the transference-counter-transference permitted recovery from withdrawal into a fantasy world.  相似文献

Animal communication systems have become closely tuned to local habitat conditions as populations have adjusted to different long-term environmental pressures. However, many habitats are now rapidly changing because of anthropogenic modification. Maintenance of effective communication systems in greatly altered environments will depend on communicative responses on both evolutionary and ontogenetic time scales. Consideration of potential acoustic challenges caused by human-generated habitat modification has important implications for basic research and conservation biology. First, the observed signal structure of individuals in altered environments may not match the normally hypothesized call structure. Second, species that either possess little ability to adapt quickly on an evolutionary time scale or have little plasticity in their communicative systems may be unable to respond to large anthropogenic alterations in their acoustic environment.  相似文献

This paper reports data and scholarly opinion that support the perception of systemic flaws in the management of scientific professions and the research enterprise; explores the responsibility that professional status places on the scientific professions, and elaborates the concept of the responsible conduct of research (RCR). Data are presented on research misconduct, availability of research guidelines, and perceived research quality. An earlier version of this paper was presented at an International Conference on “Conflict of Interest and its Significance in Science and Medicine” held in Warsaw, Poland, 5–6 April, 2002. The opinions expressed herein are those of the author and do not necessarily represent the views of the Office of Research Integrity, the U.S. Department of Health and Human Services, or any other federal agency.  相似文献

This paper reviews the international scientific evidence on the effectiveness of secondary prevention interventions for young drug users. The review provides insight into the effectiveness of interventions that have been evaluated using moderately strong research designs. Most of the studies included are from the United States of America. Some interventions are effective in reducing drug use and associated problems while others have no or mixed effect. Those successful in reducing drug use include behavior therapy, Minnesota 12-step programs, residential care, and general drug treatment. Those with either no effect or mixed effect include schools interventions. Involving parents and other agencies may enhance an intervention's effect. There is a lack of good quality studies outside the USA. Future interventions should focus on either low- or high-risk groups of young drug users. Future research should be conducted on a wider range of services for young people and include non-medical outcomes such as communication skills, schooling, employment, family relations, and economic costs.  相似文献

This study evaluated the efficacy of adding contingency management techniques to vocational rehabilitation (VR) to improve treatment outcome as measured by entry into competitive employment. Nineteen dually diagnosed veterans who entered VR in the Veterans' Administration's compensated work therapy (CWT) program were randomly assigned to CWT (n = 8) or to CWT with enhanced incentives (n = 11). Over the first 16 weeks of rehabilitation, those in the incentives condition could earn up to dollar 1,006 in cash for meeting two sets of clinical goals: (a) remaining abstinent from drugs and alcohol and (b) taking steps to obtain and maintain a competitive job. Results indicate that relative to participants in the CWT-only group, those in the incentives condition engaged in more job-search activities, were more likely to remain abstinent from drugs and alcohol, were more likely to obtain competitive employment, and earned an average of 68% more in wages. These results suggest that rehabilitation outcomes may be enhanced by restructuring traditional work-for-pay contingencies to include direct financial rewards for meeting clinical goals.  相似文献
