Verbal fluency is commonly used as a proxy measure of executive functioning, as it involves cognitive flexibility, working memory, and inhibitory control. Previous research has demonstrated that crosswords can be a useful means of improving verbal fluency, results consistent with the cognitive reserve hypothesis; the form of verbal fluency affected has, however, differed across studies. The present study sought to assess the extent to which it was possible to target phonemic (PVF) and semantic verbal fluency (SVF) separately through word puzzles designed to focus on semantic/thematic and structural clues respectively. Fifty-three university students were randomly assigned to one of three groups: semantic/thematic, structural, or a daily diary control group. They were assessed on PVF and SVF at baseline, and immediately following a four-week intervention. Age, sex, and depression scores were controlled for. A 2 × 3 mixed ANCOVA showed that the structural group improved significantly more in PVF during the intervention period than did the semantic/thematic or control groups, with the improvement linked to improved switching performance. The effect size was large. No significant difference in improvement in SVF emerged, although the effect size was moderate. The findings support the notion that it is possible to improve specific forms of verbal fluency through tailored brief word-puzzle interventions.  相似文献

The purpose of this research was to better understand the substance use and sexual risk taking behavior among high-risk adolescent populations placed in residential treatment facilities, including those in the foster care and juvenile justice systems. The primary predictors considered in this study included caregiver support, caregiver closeness, other adult support, adolescent self-disclosure/communication with caregiver, caregiver expectations about sexual behavior, and peer influence regards to drugs/alcohol and sexual behavior. Participants included 120 adolescent females in grades 7 to 12 (median grade?=?10; mean age 15.7 years), primarily African American (57.2 %) and White (29 %), in a residential treatment setting in a large urban area in the Midwest. Caregiver support and self-disclosure/communication with caregivers predicted condom use at most recent intercourse, but variables related to substance use were most consistently predictive of sexuality variables including onset and frequency of behavior. None of these support variables significantly predicted onset and frequency of substance use. Caregiver support was the contributing variable in predicting academic achievement.  相似文献

The purpose of this study was to determine the prevalence and individual risk factors of people who trade or sell sex among sexually active individuals seeking HIV and sexually transmitted infection (STI) testing. Using electronic agency records, an analysis of the characteristics of 5,029 youth and adults who voluntarily obtained HIV and STI testing was conducted. Multiple imputation procedures for missing data from 3 variables and logistic regression were conducted. A total of 128 individuals reported having traded sex. Nine variables had statistically significant associations with trading sex. Individuals who identified as White and female had lesser odds of trading sex, whereas individuals who were transgender, were living in a shelter, had been sexually assaulted, had a previous STI, had high-risk sex, or used drugs had greater odds of trading sex. Elevated levels of high-risk behavior in addition to sexual trauma should be considered in intervention research and community health practice. Implications for service providers and researchers are discussed.  相似文献

This paper provides an overview of a conceptual model that integrates theories of social ecology, minority stress, and community readiness to better understand risk for and outcomes of intimate partner violence (IPV) among LGBTQ+ college students. Additionally, online survey data was collected from a sample of 202 LGBTQ+ students enrolled in 119 colleges across the United States to provide preliminary data on some aspects of the proposed model. Results suggested that students generally thought their campuses were low in readiness to address IPV; that is, students felt that their campuses could do more to address IPV and provide IPV services specific to LGBTQ+ college students. Perceptions of greater campus readiness to address IPV among LGBTQ+ college students was significantly and positively related to a more favorable LGBTQ+ campus climate and a greater sense of campus community. Additionally, IPV victims were more likely to perceive higher levels of campus community readiness than non‐IPV victims. There was no association between IPV perpetration and perceptions of campus community readiness. Greater sense of community was marginally and inversely related to IPV victimization and perpetration. Sense of community and LGBTQ+ campus climate also varied to some extent as a function of region of the country and type of institution. Implications for further development and refinement of the conceptual model, as well as future research applying this model to better understand IPV among sexual minority students are discussed.  相似文献

This meta‐analysis of 152 published posttraumatic stress disorder (PTSD) clinical trials from 1990 to 2012 concluded that counseling generally produced a small to large effect of treatment across all comparison conditions at termination (d+ = 0.30 to 0.89). These gains were maintained at longest follow‐up (d+ = 0.58 to 0.86) for the wait‐list, treatment‐as‐usual, and single‐group comparisons, but not for the follow‐up placebo comparison (d+ = 0.15), probably because of the low power (j = 3 placebo studies). Clinical trial findings were synthesized using a random‐effects model. No effects of publication bias or moderating variables were evident. No difference was found between trauma‐focused and non‐trauma‐focused approaches. Implications for counseling practice and future PTSD outcome research are addressed.  相似文献

The aim of this study was to explore the interplay between working memory (WM), dispositional optimism, and depressive symptoms in participants across a wide age band (16–79 years) in a nonclinical sample using a computer‐based interface. We administered tests of visuospatial WM (processing and recall), dispositional optimism (optimism and pessimism), and self‐reported depression. There were two main findings: 1) both optimism and pessimism were independent predictors of a self‐rated depression score; 2) WM recall scores predicted both optimism and pessimism. The findings suggest the following pattern: according to the negativity bias, a pessimistic outlook presents as a strong stimulus for attentional allocation, which results in depression. However, a strong WM can counter this pattern, as individuals can allocate attention to the weaker stimulus, which is an optimistic outlook. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献
