The development of preschool children of Aboriginal heritage is jeopardized by the inter-generational transmission of risk that has created, and continues to create, social disadvantage. Early intervention programs are intended to mitigate the impact of social disadvantage. Yet, evidence of the effectiveness of these programs for children of Aboriginal heritage is limited. The purpose of this study was to examine the effects of a two-generation, multi-cultural preschool program on 45 children of Aboriginal heritage and their caregivers. We used a single-group, pretest (program intake)/posttest (program exit) design with follow-up when the children were 7 years old. We used an observational measure of child receptive language (Peabody Picture Vocabulary Test–III) and caregiver-reported measures of child development (Nipissing District Developmental Screen), risk for child maltreatment (Adult-Adolescent Parenting Inventory; AAPI), parenting stress (Parenting Stress Index; PSI), self-esteem (Rosenberg Self-Esteem scale; RSE), and life skills (Community Life Skills scale; CLS). Using paired t-tests we found statistically significant increases in child receptive language scores between intake and exit, and repeated-measures ANOVA showed that these improvements were maintained up to age 7 years. For caregivers, Pearson’s correlations demonstrated that risk for child maltreatment, parenting stress, self-esteem, and life skills were stable over time. Results of this study suggest that children of Aboriginal heritage can benefit from participation in a two-generation, multi-cultural preschool program. Their caregivers may have received greater benefit if issues of intergenerational transmission of the negative influences of residential schools were addressed as part of programming.  相似文献

Suicide is a leading cause of death among older adolescents and young adults; however, few studies have prospectively examined risk for suicidal ideation. The present study in older adolescents and young adults investigated whether two personality traits previously implicated in risk for suicidal ideation, neuroticism and extraversion, as well as certain aspects of interpersonal functioning, prospectively predicted endorsement of suicidal ideation during depressive episodes. Participants (n=117) are a subset of the Northwestern-UCLA Youth Emotion Project sample, which started with a group of high school juniors oversampled for high neuroticism. Baseline interpersonal functioning was measured using the Life Stress Interview. Baseline personality trait composite scores were created from multiple inventories. Depressive disorders and suicidal ideation were assessed at the baseline and three annual follow-up interviews using the SCID. Cox regression was employed to predict suicidal ideation during depressive episodes diagnosed at any follow-up interview. Results showed that baseline extraversion inversely predicts suicidal ideation in males only, and that baseline interpersonal problems in one's social circle, regardless of gender, predict suicidal ideation during depressive episodes.  相似文献

The hypothalamic-pituitary-adrenal axis is thought to play a role in the pathogenesis of depression. In the study reported here, we tested the hypothesis that parenting behavior moderates the relation between parents' lifetime history of depression and their offspring's cortisol reactivity to a psychosocial stressor. We exposed 160 preschool-age children to stress-inducing laboratory tasks, during which we obtained four salivary cortisol samples. Parents completed clinical interviews and an observational parent-child interaction task. The results confirmed our hypothesis: The offspring who evidenced high and increasing cortisol levels were those whose parents had a history of depression and demonstrated hostility toward their child. This moderating effect was specific to offspring who were exposed to maternal depression during the first few years of life. As do findings in animals, results of this study underscore the importance of the early rearing environment in the intergenerational transmission of stress sensitivity.  相似文献

Under the assumption of the principle of cooperation (Grice, 1989), a statement such as "some eels are fish" is thought to be false since it contains less information than is considered sufficient. However, the statement is logically sound since the meaning of "some" is compatible with "all". Currently, the primary interpretation of such underinformative statements remains subject to debate. According to Levinson (2000), the pragmatic "some but not all" interpretation is the default interpretation, while others (e.g., Sperber & Wilson, 1995) argue that this pragmatic interpretation only comes to the fore when relevant within the context and is thus considered secondary to the logical "some and perhaps all" interpretation. In this study, three factors that may influence the answer pattern are studied: task load, working memory capacity, and repetition of the statements. In Experiment 1, we used a secondary task paradigm to manipulate the cognitive load under which a number of underinformative statements had to be judged. We observed that for participants with a rather limited working memory span it is harder to reach a pragmatic interpretation under cognitive load. In Experiment 2, we manipulated the repetition of the statements. We observed that with a higher number of filler statements, participants produced fewer consistent answer patterns. This study provides further evidence against the automaticity of the pragmatic interpretation: It shows that the pragmatic interpretation requires more cognitive effort than the logical interpretation and that increasing the number of filler statements inhibits the development of a response strategy.  相似文献

Considering the implications of social exchange theory as a context for social role behavior, we tested relations between ethical leadership and both person- and task-focused organizational citizenship behavior and examined the roles played by employee gender and politics perceptions. Although social exchange theory predicts that ethical leadership is positively associated with citizenship, social role theory predicts that the nature of this relationship may vary on the basis of gender and politics perceptions. Results from data collected from 288 supervisor-subordinate dyads indicate that the pattern of male versus female employees' citizenship associated with ethical leadership depends significantly on their perceptions of politics. Implications for theory and practice are discussed.  相似文献

Based on the cognitive-social health information processing model, we identified cognitive profiles of women at risk for breast and ovarian cancer. Prior to genetic counselling, participants (N = 171) completed a study questionnaire concerning their cognitive and affective responses to being at genetic risk. Using cluster analysis, four cognitive profiles were generated: (a) high perceived risk/low coping; (b) low value of screening/high expectancy of cancer; (c) moderate perceived risk/moderate efficacy of prevention/low informativeness of test result; and (d) high efficacy of prevention/high coping. The majority of women in Clusters One, Two and Three had no personal history of cancer, whereas Cluster Four consisted almost entirely of women affected with cancer. Women in Cluster One had the highest number of affected relatives and experienced higher levels of distress than women in the other three clusters. These results highlight the need to consider the psychological profile of women undergoing genetic testing when designing counselling interventions and messages.  相似文献

Within the work–family literature little is known about the work–family challenges and opportunities faced by families that have one or more children with autism spectrum disorder. However, it has been consistently demonstrated that parents of children with autism spectrum disorder are at a higher risk of experiencing a host of negative outcomes. Using a qualitative design, within grounded theory, the present study sheds light on the needs, experiences, and challenges that parents of children with autism spectrum disorder face and also offers insight into ways to expand the scope of work–family research in this area. The present research provides evidence of how the family domain can greatly impact experiences and decisions made in the work domain for families with special needs. The present research adds to the small but growing literature examining the interplay between home and work life for families with special needs and demonstrates that this is an important research domain in need of additional conceptual and empirical consideration.  相似文献

The application of motivational interviewing (MI) principles in modified interpersonal group therapy (MIGT) addresses two gaps in the literature. First, it explicitly extends MIGT to non-abstinent, addicted patients who are in the precontemplative and contemplative stages of change in contrast to most MIGT models where abstinence is usually required. Second, it provides a novel, process-oriented group intervention for MI, in contrast to current applications of group-based MI which are more structured in their format. The main modification in technique was to prioritize the horizontal exploration of substance use disclosures with a focus on the here-and-now experience of disclosure and the interpersonal impact on the group, in order to: (1) encourage members to openly discuss their ambivalence and shifting motivational states, (2) harness the evocative impact of substance use disclosures between members to elicit change talk (self-motivational statements), and (3) selectively reinforce change talk when it emerges from these exchanges. The authors illustrate these concepts with a case report of an open-ended MIGT group with comorbid mental illness and addiction.  相似文献

We examined the influences of different facets of psychological collectivism (Preference, Reliance, Concern, Norm Acceptance, and Goal Priority) on team functioning at 3 different performance depictions: initial team performance, end-state team performance, and team performance change over time. We also tested the extent to which team-member exchange moderated the relationships between facets of psychological collectivism and performance change over time. Results from multilevel growth modeling of 66 teams (N = 264) engaged in a business simulation revealed differential effects across facets of psychological collectivism and across different performance measurements. Whereas facets concerned with affiliation (Preference and Concern) were positively related to initial team performance, reliance was negatively related to initial team performance. Goal Priority was a strong predictor of end-state performance. Team-member exchange moderated the relationship between performance change and 3 of the 5 facets of psychological collectivism (Preference, Reliance, Norm Acceptance). Implications for team composition and team training are discussed.  相似文献

To investigate children’s theories of motivation, we asked 166 children (8-12 years of age) to rate the effect of various motivational strategies on task interest, over the short and long terms, in activities described as appealing or unappealing. Children viewed the rewards strategy as resulting in greatest interest except when implemented over the long term for appealing activities. Individual difference analyses revealed that some children held operant theories of motivation, in which rewards were central, and others held hybrid theories, in which rewards were key, but some allowance was made for interest to be self-sustaining in the absence of inducements. Children’s theories predicted their academic self-regulation. Their theories are discussed relative to an expert theory of motivation.  相似文献
