This study examined the role of participation in a year-long school-based group mentoring program, Project Arrive (PA), on increasing resilience during the first year of high school among students identified as being at high risk for school dropout. Participants were 114, ninth grade students taking part in one of 32 PA mentoring groups, and 71 statistically matched comparison students (53% male, 75% eligible for free/reduced-price lunch, 62% Latinx). Using a propensity score with inverse probability of treatment weighting (IPTW) to reduce selection bias, and a multi-level model to account for non-independence of data within mentoring groups, we examined changes from pre-test to program exit on seven external resilience resources (developmental supports and opportunities) and four internal resilience assets (personal strengths). At program exit, PA participants had higher adjusted means than comparisons on six external resources, including school support, school belonging, school meaningful participation, peer caring relationships, prosocial peers, and home meaningful participation. PA participants also had higher adjusted means on one internal asset, problem solving. Results point to the promise of group mentoring as an approach for increasing resilience among academically vulnerable adolescents. 相似文献

Psychopathology poses a risk for optimal parenting. The current study explored antenatal caregiving representations as markers for later risk of nonoptimal maternal behavior among mothers with severe mental illness. Sixty-five mothers diagnosed with psychosis, bipolar disorder, depression (psychopathology group), and nonclinical controls participated in a longitudinal study from pregnancy to 16 weeks after birth. Mental health diagnoses and caregiving representations were assessed during pregnancy. Maternal behavior was assessed during the 5-min recovery phase of the still-face paradigm at 16 weeks. Mothers with psychopathology reported significantly higher levels of “heightened” caregiving representations (i.e., separation anxiety from the child) than did controls. The only significant diagnostic group difference in perinatal maternal behavior was that mothers diagnosed with depression exhibited more overriding-intrusive behavior than did nonclinical control mothers. Regression modeling results showed that antenatal caregiving representations of “role reversal” predicted significantly lower levels of sensitivity and higher levels of overriding-intrusive behavior independent of the effect of psychopathology. The findings can be interpreted in the context of representational transformation to motherhood during pregnancy. The results provide preliminary evidence for the potential of a new questionnaire measure of caregiving representations as a screening instrument for antenatal representational risk. 相似文献

Impairment in semantic association has been reported in bipolar disorder (BD) and schizophrenia (SZ) patients and could underlie abnormal speech patterns in both disorders. In this study, we compared the electrophysiological semantic processing features in patients with these two disorders. Participants (n = 61; BD = 19; SZ = 19; healthy controls [HCs] = 23) were administered a semantic judgment task and event‐related potentials (ERPs) were recorded. Responses of the two patient groups were significantly slower than HCs, but comparable behavioral semantic priming effects were observed in both patient groups. The N400 priming effect was observed in all groups, with a delayed peak in the two patient groups. The N400 effect was enhanced for both BD and SZ patients over the left frontal and frontal pole region, but SZ patients showed additional reduction of N400 over the right posterior and occipital regions. The N400 mean amplitudes for related targets correlated with less severe negative symptoms in patients with SZ. Discriminant functional analysis using reaction time and N400 measures successfully classified 82% of the participants into their respective clinical groups. These results suggest that patients with BD and SZ have both overlapping and distinctive semantic processing dysfunction. These findings are consistent with the continuum conceptualization of these disorders, but also offer some support for the traditional Kraepelinian dichotomy. 相似文献

The present study aimed to examine the effect of incentive salience on the motivational behavior and pleasure experience of 35 healthy participants during reward pursuits. The findings suggest that high incentive salience promotes motivation in effort‐expenditure decision‐making, effort exertion, and pleasure experience. 相似文献

The self-reported violent experiences of adolescents living in a public-subsidized urban high-rise building were examined. This effort was part of an interdisciplinary, community-university collaboration program called the HOME (High-rise On-site Multifamily Environments) Family Support Project. A survey of violent experiences and a one-on-one structured interview were conducted with 20 adolescent residents. Results of the quantitative and qualitative analyses revealed high degrees of exposure to violence among these adolescents, concerns for their personal safety, as well as insights into what they believe adults could and should be doing to address increasing levels of community violence. The implications of these results for conducting ecologically valid research on sensitive issues with adolescents and for family support program planning are discussed. 相似文献

Age differences in coping resources and satisfaction with life among middle-aged,young-old,and oldest-old adults 总被引:1,自引:0,他引:1

The authors examined age differences in perceived coping resources and satisfaction with life across 3 older-adult age groups (45-64, 65-74, and 75 years and older). The 98 participants represented healthy, socially active, community-residing adults. Group comparisons were made on 12 individual coping scales, and an overall coping resource effectiveness score was computed. No significant differences were found for 11 of the coping resources or for overall coping resource effectiveness. Similar consistencies in life satisfaction were found across the 3 age groups. The findings indicate that (a) for healthy adults, the oldest old cope at least as effectively as their younger counterparts, despite their likelihood of encountering increased levels of stress; and (b) psychologically, old age may be viewed as a time of resilience and fortitude. 相似文献

The Color Trails Test developed as a culturally fair analogue of the Trail Making Test, was used to examine the relationship between the two tests with 35 undergraduate Chinese in Hong Kong recruited as the subjects. The scores on these two tests of the 12 men and 23 women were significantly correlated .71. The equivalence of the Trail Making and Color Trails Tests when applied to Chinese in Hong Kong was discussed. 相似文献

Transfer-appropriate processing (TAP), as applied to implicit memory, has tended to emphasize general forms of processing (e.g., perceptual or conceptual processing). In the present studies, the TAP principle was employed in a more specific manner in order to more precisely assess the relations between the processing engaged during first exposure and that engaged during second exposure to items. Thirteen experiments used a two-phase, cross-task design in which participants engaged in different combinations of seven specific intentional tasks between Phase 1 and Phase 2. Maximum repetition priming was found when tasks were the same in Phases 1 and 2. When Phase 1 and Phase 2 tasks differed, there were lesser, or no, repetition priming effects, depending on the particular combination of tasks. The results demonstrate the importance of the specific intentional processes engaged during repetition priming and the potential heuristic value of TAP, as a principle and methodology, for exploring the organization of memory and related process models. 相似文献
