Alarming numbers of military veterans end their lives each day which has a profound effect on the military population. This study examines a sample (N?=?434) of suicide-exposed (i.e., personally knowing someone who has died by suicide) veterans to determine whether the proportion of individuals who report high impact from suicide exposure and those who have clinically-significant posttraumatic stress disorder symptoms is related to marital status. Using Hill’s (Social Casework 49: 139–150, 1958) ABC-X model for conceptualizing the relationships between variables, mean scores for posttraumatic stress disorder were significantly different between groups, and the odds of a married veteran reporting high-impact suicide exposure were 2.19 times lower than the odds of a single veteran reporting high-impact. Likewise, the odds of a veteran with high-impact suicide exposure having clinically-significant posttraumatic stress disorder symptoms were 10.04 times higher than veterans with low-impact suicide exposure. Findings indicate that veterans who are married are less likely to be highly-affected by another individual’s suicide. Thus, marriage is a protective factor for suicide-exposed veterans.  相似文献

Despite concerns surrounding depression in adolescence and the existence of effective treatments, adolescent depression often goes untreated. In 2014, only 41.2% of adolescents experiencing a major depressive episode (MDE) received mental health treatment. Parents play a key role in adolescents’ treatment utilization. We examined whether among mothers with any mental illness, mothers’ utilization of mental health treatment was associated with greater likelihood of their adolescent children who experienced an MDE receiving mental health treatment. Using nationally representative data from the National Survey on Drug Use and Health (2008–2014), we performed logistic regression analysis to model the odds of adolescents (aged 12 to 17 years) with a past year MDE receiving any mental health treatment in the past year as a function of their mothers’ mental health treatment utilization in the past year, adjusting for control variables. The rate of adolescent treatment utilization was 66% when mothers had utilized treatment, as compared to 45% when mothers did not utilize treatment (p?<?0.001). The odds of an adolescent with an MDE receiving mental health treatment were two times greater when the mother received mental health treatment as compared to adolescents whose mothers did not receive any mental health treatment (OR?=?2.09, 95% CI [1.04, 4.17]). There was no effect of adolescent gender (OR?=?1.15, 95% CI [0.40, 3.28]) or interaction between gender and mothers’ treatment (OR?=?0.95, 95% CI [0.26, 3.46]). Barriers to adolescent mental health treatment may be lower when mothers receive mental health treatment.  相似文献

Homelessness is a devastating problem that breeds far-reaching negative impacts on all aspects of children's lives, including their school experience. Fifteen homeless, African-American children in grades 3 through 6 were interviewed about their experiences at school, as well as their future educational and career aspirations. Findings of a grounded theory analysis reveal that these children struggled to envision a safe future through seeking predictability, personal connections, and academic achievement, and provide insight for interventions. The study examines the ways the children constructed meaning out of their school experience, understood their transitions, and set life goals. By understanding the ways these youth experience their school experience, psychologists, counselors, and educators can be better equipped to serve their needs by providing support services that support their development, by developing educational practices that shape realistic educational goals, and by moving toward systemic change through collaborating with administrators and other stakeholders.  相似文献

Quitting smoking during young adulthood can substantially reduce tobacco-related morbidity and mortality later in life. Depressive symptomatology is prevalent among smokers and increases risk for poor smoking cessation outcomes. However, few integrated behavioral interventions simultaneously target smoking and depressive symptoms and rarely have young smokers been included in the development of these interventions. In this paper we describe an 8-session behavioral activation–based treatment for smoking (BATS; MacPherson et al., 2010) adapted for youth. We conducted a series of focus groups with young adult smokers with depressive symptoms in order to modify treatment manuals to be developmentally appropriate. Subsequently, we completed a small pilot group (n = 5) of the intervention to provide preliminary data on feasibility, acceptability, and outcomes. We provide a case series of the participants in order to provide clinical illustrations of how the modified BATS treatment was implemented among young adults. Most pilot study participants exhibited smoking abstinence and smoking reductions at the end of treatment, as well as improvement in depressive symptoms and maintenance of levels of activation and environmental reward. Participants provided positive qualitative constructive feedback regarding the intervention.  相似文献

Support groups provide parents of children with Autism Spectrum Disorder (ASD) with additional support which they may not receive from health care professionals. Rapid technological growth has increased the opportunity for parents to access information and support. In this study, we used a qualitative phenomenological design to explore the use of a social media support group, on WhatsApp, to provide support to parents of children with ASD. We used convenience sampling to select six participants who had a child diagnosed with ASD who was in the foundation or intermediate phase at school and between the ages of 5 and 12 years, had been a part of the WhatsApp support group for 6 months or longer, and lived in KwaZulu-Natal, South Africa. Data analysis revealed eight emergent themes, (a) communication support, (b) behavior support, (c) feeding support, (d) emotional support, (e) informational support, (f) the presence of a professional, (g) positive experiences in the group, and (h) limitations of the group. Findings indicate managing behavioral difficulties and emotional support for caregivers were the core functions of the group, and having a professional on the group served as a valuable resource. The use of a social media support group on WhatsApp provided ongoing support to parents of children with ASD, implying that such a group may have clinical significance for use by practitioners as well as the creation of similar groups on other platforms.  相似文献

The present study examined whether beliefs about the importance of thoughts (i.e., thought–action fusion; TAF) are related to the target subject of the negative thought. One hundred and seven undergraduate students were randomly assigned to imagine either a beloved relative or a stranger being diagnosed with cancer and provided in vivo ratings of anxiety, likelihood, moral wrongness, urge to neutralize, and how upsetting the event would be if it occurred. Results indicated that thinking of a relative being diagnosed with cancer provoked more distress, urges to neutralize, and higher estimates of likelihood, as well greater use of mental neutralizing behaviors, compared to thinking of a stranger. Contrary to our prediction, the groups did not differ in their ratings of the moral wrongness. These findings broadly support the assertion that the more personally significant a negative intrusive thought, the more it will provoke distress and urges to neutralize. Results are discussed in terms of the cognitive model of obsessions and clinical implications are addressed.  相似文献

Research on age-related cognitive change traditionally focuses on either development or aging, where development ends with adulthood and aging begins around 55 years. This approach ignores age-related changes during the 35 years in-between, implying that this period is uninformative. Here we investigated face recognition as an ability that may mature late relative to other abilities. Using data from over 60,000 participants, we traced the ability to learn new faces from pre-adolescence through middle age. In three separate experiments, we show that face learning ability improves until just after age 30 – even though other putatively related abilities (inverted face recognition and name recognition) stop showing age-related improvements years earlier. Our data provide the first behavioral evidence for late maturation of face processing and the dissociation of face recognition from other abilities over time demonstrates that studies on adult age development can provide insight into the organization and development of cognitive systems.  相似文献

This article reviews various theoretical approaches political scientists employ in the analysis of religion and politics and posits culture as a conceptual bridge between competing approaches. After coming to the study of religion slowly in comparison with other social science disciplines, political science finally has a theoretically diverse and thriving religion and politics subfield. However, political scientists’ contributions to the social scientific study of religion are hampered by a lack of agreement about whether endogenous or exogenous theoretical approaches ought to dominate our scholarship. I assert that the concept of culture—and more specifically, subculture—might help create more connections across theoretical research traditions. I emphasize how the concept of religion‐based subculture is inherent in psychological, social psychological, social movement, and contextual approaches to religion and politics scholarship, and I explore these theoretical connections using the example of religion‐based “us versus them” discourses in contemporary American politics.  相似文献

People are generally skilled at using a confidence scale to rate the strength of their memories over a wide range. Specifically, low-confidence recognition decisions are often associated with close-to-chance accuracy, whereas high-confidence recognition decisions can be associated with close-to-perfect accuracy. However, using a 20-point rating scale, the authors found that the ability to scale memory strength had its limitations in that a high proportion of list items received the highest rating of 20. Efforts to induce participants to differentiate between these strong memories using emphatic instructions and alternative scales were not successful. Remember/know judgments indicated that these strong and hard-to-scale memories were often based on familiarity (not just recollection). Providing error feedback on a plurals discrimination task finally produced a high-confidence criterion shift. The authors suggest that the ability to scale strong (and almost perfectly accurate) memories may be limited because of the absence of differential error feedback for very strong memories in the past (the kind of differential error feedback that may account for the memory-scaling expertise that participants otherwise exhibit).  相似文献
