Executive functions (EFs) are involved in the attainment, maintenance, and integration of information; these functions may play a key role in cognitive and behavioural outcomes in children treated for medulloblastoma (MB). At present, it remains unclear which EFs are most sensitive to the treatment effects for MB and whether damage to cerebrocerebellar circuitry is associated with EF. We completed a comprehensive evaluation of EF in 24 children treated for MB and 20 age‐matched healthy children (HC) and distilled these measures into components. Six components (C1–C6) were extracted from our model, reflecting dissociable constructs of EF: C1 = cognitive efficiency; C2 = planning/problem‐solving; C3 = positive cognitive emotion regulation; C4 = working memory; C5 = negative cognitive emotion regulation; and C6 = mixed cognitive emotion regulation. Group differences were found for C1, C2, C3, and C4; the MB group showed poorer performance on EF tasks and made less use of positive cognitive emotion regulation strategies relative to HC. Compromise to cerebrocerebellar microstructure – cerebro‐ponto‐cerebellar and cerebello‐thalamo‐cerebral pathways – was evident in children treated for MB compared to HC. We found that cerebrocerebellar circuitry has a mediating effect on one component of EF following treatment for MB – working memory. 相似文献

This study investigated the relationship between physical and mental health and psychosocial variables and recent (within
the last 12 months) mental health service use among 240 medical patients recruited from general and specialty outpatient clinics
at an academic medical center. Results indicated 43.3% of the participants had recently received mental health services in
the form of psychotropic medication (75%), psychotherapy (2%), or a combination of these treatments (20.2%). Among patients
with moderate to severe symptoms of anxiety or depression, approximately two-thirds were receiving mental health treatment.
Moreover, four variables (healthcare provider referral for mental health services, perceived need for mental health services,
prior use of mental health services, and frequency of medical appointments) were significant unique predictors of recent mental
health service use. This suggests collaborative/integrated medical care may increase needed mental health service use. 相似文献

ABSTRACT— Little is known about the associations between premenstrual depressive symptoms and specific physical symptoms of the menstrual cycle. In a nonclinical sample of 183 female university students, six physical symptoms of the menstrual cycle (headaches, skin changes, gastrointestinal problems, breast changes, and coagulation and heaviness of menstrual bleeding) were tested for their associations with premenstrual depressive symptoms. The physical symptoms explained nearly 30% of the variance in depressive symptoms. Moreover, when the summed score for all six physical symptoms was used as a predictor of depressive symptoms, a strong linear effect and a moderate curvilinear effect were observed. These results could not be explained by response bias or by the presence of a small group of highly depressed individuals. This study emphasizes the need to consider physical symptoms of the menstrual cycle to better understand premenstrual depressive symptoms, and suggests that the contribution of the menstrual cycle to depressive symptoms in the general population is underrecognized. 相似文献

The present study investigated the relevance of the “aspiration–expectation gap” and traditional gender differences among urban youth in middle school and high school (N = 294). Results failed to indicate a significant difference between the occupational prestige levels of aspired and expected careers, but did indicate a significant difference between aspired and expected levels of education. In general, the proportion of girls significantly outweighed the proportion of boys in traditionally “masculine” occupations with high levels of prestige; girls also had higher levels of occupational prestige than boys in terms of careers they hoped and expected to obtain. Black and bi/multi-racial youth expected to have higher levels of education than White youth. 相似文献

Considerable research has demonstrated that substance use and delinquency during early adolescence can have long-term negative health consequences. As the correlates of these behaviors cross levels and contexts, it is likely that a social ecological approach will provide insight to inform community prevention. This approach informs the present study, which focuses on developing a multiple-method measurement strategy to examine associations among community risks, resources, and rates of early adolescent substance use and delinquency in 28 rural and small town communities. Measures include five domains of community risk, four domains of community resources, and population rates of early adolescent substance use and delinquency. Results demonstrated that several measures of context were significantly associated with community rates of adolescent substance use and delinquency, and different risks and resources appear important for different outcomes. Multiple associations were curvilinear, and interactions may also be important. Findings suggest that it may be worthwhile to create and test new intervention strategies that target community factors in the pursuit of prevention. 相似文献

In this study, two longitudinal models of early adolescent risky sexual behaviors (RSB) were compared using a pooled sample of 267 Canadian and Italian adolescents (55% females; 53% Canadians) assessed yearly from grade 8 to 10. We focused on parenting practices (monitoring, control, limit setting), adolescent problem behaviors (antisocial behaviors, substance use) and their friends' deviance (antisocial behaviors, substance use) as predictors of condom use frequency and lifetime number of sexual partners. The socialization model postulates that youths' problem behaviors and RSB are behaviors learned within the friendship network where deviancy training can occur. The selection model posits that delinquent youth tend to affiliate with each other, and that RSB is one of many behaviors that can form the basis of selection. Using structural equation modeling, this study showed that the socialization model was the most accurate to explain the emergence of RSB. A full mediation of parenting practices, passing through deviant friends and youths' problem behavior, was observed for condom use. The same process applied to number of sexual partners, but a direct effect for parenting practices was also found. 相似文献

Social scientific investigation into the religiospiritual characteristics of American Indians rarely includes analysis of quantitative data. After reviewing information from ethnographic and autobiographical sources, we present analyses of data from a large, population-based sample of two tribes (n = 3,084). We examine salience of belief in three traditions: aboriginal, Christian, and Native American Church. We then investigate patterns in sociodemographic subgroups, determining the significant correlates of salience with other variables controlled. Finally, we examine frequency with which respondents assign high salience to only one tradition (exclusivity) or multiple traditions (nonexclusivity), again investigating subgroup variations. This first detailed, statistical portrait of American Indian religious and spiritual lives links work on tribal ethnic identity to theoretical work on America's "religious marketplace." Results may also inform social/behavioral interventions that incorporate religiospiritual elements. 相似文献

Mizuko kuyō, the popular Japanese Buddhist memorial service for aborted fetuses, has been increasingly appropriated by both sides of the contentious American abortion debate. In the wake of exposure to the idea of mizuko kuyō, both pro-life and pro-choice Buddhist appropriators resort to discussions of the ritual because they feel it helps them strengthen the weaknesses of their own sides and undermine the positions of their opponents. Pro-life Americans use mizuko kuyō to prove that they care about women, not just fetuses, and that their convictions do not arise simply out of private religious feelings but objective psychological and medical facts. Pro-choice Americans, on the other hand, use mizuko kuyō to demonstrate that they care about families and children, not just women, and that they are sensitive not only to the secular but also the religious aspects of life and abortion. In the process, pro-life Christians, who seem to be primarily motivated by their exclusivist and authoritarian Biblical convictions, turn for support to a non-theistic religion they otherwise oppose; pro-choice feminists, who seem to have chiefly secular reasons for supporting abortion rights, turn for support to a supernatural entity and his retinue of angry fetal ghosts. 相似文献

Defendants who are accused of serious crimes sometimes feign amnesia to evade criminal responsibility. Previous research has
suggested that feigning amnesia might impair subsequent recall. In two experiments, participants read and heard a story about
a central character, described as “you,” who was responsible for the death of either a puppy (Experiment 1) or a friend (Experiment
2). On free and cued recall tests immediately after the story, participants who had feigned amnesia recalled less than did
participants who had recalled accurately. One week later, when all participants recalled accurately, participants who had
previously feigned amnesia still performed worse than did participants who had recalled accurately both times. However, the
participants who had formerly feigned amnesia did not perform worse than did a control group who had received only the delayed
recall tests. Our results suggest that a “feigned amnesia effect” may reflect nothing more than differential practice at recall.
Feigning amnesia for a crime need not impair memory for that crime when a person later seeks to remember accurately. 相似文献
