Two patients experiencing recurring trisomic pregnancies involving a different chromosome each time are presented. Mechanisms to explain recurrent trisomies include a gene or genes predisposing to nondisjunction in general or to nondisjunction of the acrocentric chromosomes, maternal age effects, and germ-line mosaicism. Genetic counseling is complicated by the lack of a clear explanation for the recurrences, difficulty in quoting a specific recurrence risk, concern regarding the risk for uniparental disomy, and the frustration, grief and guilt reactions of the patients. 相似文献

The current study is a pilot evaluation of a six-week psychoeducational-support group based in an ambiguous loss framework for family members of people who hoard. Findings suggest that participants who completed the six-week intervention group (N?=?8) indicated positive results at the two-month follow up interview, reporting an increased understanding of family members’ hoarding behaviors and their own experiences related to the hoarding behavior and its impact on the family system. Participants also reported that having personal and professional support from others who understand hoarding behavior was helpful to them in lowering psychological distress and improving interactions with their family members. 相似文献

The pipeline toward careers in science, technology, engineering, and mathematics (STEM) begins to leak in high school, when some students choose not to take advanced mathematics and science courses. We conducted a field experiment testing whether a theory-based intervention that was designed to help parents convey the importance of mathematics and science courses to their high school-aged children would lead them to take more mathematics and science courses in high school. The three-part intervention consisted of two brochures mailed to parents and a Web site, all highlighting the usefulness of STEM courses. This relatively simple intervention led students whose parents were in the experimental group to take, on average, nearly one semester more of science and mathematics in the last 2 years of high school, compared with the control group. Parents are an untapped resource for increasing STEM motivation in adolescents, and the results demonstrate that motivational theory can be applied to this important pipeline problem. 相似文献

Research on the effects of deviance during group decision making has shown that although it can lead to increased innovation and creativity within the group, group members often dislike the deviant member and rate group morale as lower because of dissent during the decision‐making process. The current study (N = 101) uses an information processing approach to examine the effect of deviance on decision outcomes as well as investigate how the perceived position of group members can influence whether they are given leeway to voice dissent. Results found that deviance can improve group decision making without incurring social costs when a deviant group member occupies a central position within the group. These findings are novel within the field of deviance research yet are consistent with research on group criticism and idiosyncrasy credit and therefore have significant implications for literature on the effect of group deviance and the application of deviance techniques within organisational and educational settings.

Adolescents are at high risk for violence exposure and initiation of drug use. Co-occurring substance use and trauma exposure are associated with increased risk of mental health disorders, school underachievement, and involvement with multiple systems of care. Coordination and integration of systems of care are of utmost importance for these vulnerable youth. This study delineates the negative sequelae and increased service utilization patterns of adolescents with a history of trauma, substance abuse, and co-occurring trauma and substance abuse to support the need for integrated mental health and substance abuse services for youth. Data from two national sources, the National Child Traumatic Stress Network and Center for Substance Abuse Treatment demonstrate the increased clinical severity (measured by reports of emotional and behavioral problems), dysfunction, and service utilization patterns for youth with co-occurring trauma exposure and substance abuse. We conclude with recommendations for an integrated system of care that includes trauma-informed mental health treatment and substance abuse services aimed at reducing the morbidity and relapse probability of this high-risk group. 相似文献

Acceptance and Commitment Therapy for adults who stutter: Psychosocial adjustment and speech fluency
The aim of the present study was to assess the effectiveness of an Acceptance and Commitment Therapy group intervention program for adults who stutter (N = 20). The program consisted of 2-h therapeutic sessions conducted weekly for eight consecutive weeks. It was an integrated program designed to improve: (a) psychosocial functioning, (b) readiness for therapy and change, (c) utilisation of mindfulness skills and psychological flexibility, and (d) frequency of stuttering. The findings provide innovative evidence for Acceptance and Commitment Therapy as an effective intervention with statistically significant improvements in psychosocial functioning, preparation for change and therapy, utilisation of mindfulness skills, and overall speech fluency. Follow-up data collected at three months post-treatment revealed that therapeutic gains were successfully maintained over time. These findings enhance the understanding of the impact of stuttering on psychological wellbeing and offer a new perspective on what might constitute successful stuttering treatment. Further, clinical research support is provided for Acceptance and Commitment Therapy delivered in a group format as a promising and novel intervention for adults who stutter.Educational objectives: The reader will be able to: (a) appreciate the potential for Acceptance and Commitment Therapy for adults who stutter; (b) identify the improvements participants experienced in psychosocial functioning and frequency of stuttered speech; (c) appreciate the six core processes of Acceptance and Commitment Therapy; and (d) appreciate the differences between an ACT model of intervention for adults who stutter compared to a CBT approach. 相似文献

Culture has been shown to influence response styles. The authors conducted two studies to test the notion that African Americans would be more likely to respond to racism directly, whereas Asian Americans would be more likely to respond indirectly and therefore more subtly. Study 1 showed that Black women subjected to a racist comment from a confederate during an online interaction were more likely than Asian women to verbally reproach the perpetrator. These group differences were not present when the outcome measure was indirect responding--administration of good/bad jellybeans. Study 2 used an online format to demonstrate that Asian women were more likely than Black women to say they would not respond directly to a racist comment. This group difference in unwillingness to confront was significantly mediated by a goal of maintaining peace with their interaction partner. Implications of these findings for the study of discrimination, coping, and well-being are discussed. 相似文献
