Although both have been used in studies of the impact of mental illness on the family, the constructs of caregiver strain (often referred to as burden of care) and psychological distress have not been clearly distinguished. The vagueness surrounding these constructs, and the lack of a cohesive conceptual framework for understanding how they relate, leads to contradictory interpretations of results. This compromises the building of the knowledge base needed to develop and evaluate interventions to support families as they struggle to meet the needs of their children with emotional and behavioral challenges. We utilized the ABCX Model as a framework for understanding caregiver strain and its relationship to psychological distress. Structural equations modeling was used to test the hypothesized relationship between caregiver strain and psychological distress, as well as the role of key child and family variables. These included child symptoms, stressful life events, social support, family functioning, and material resources. Our findings indicated that caregiver strain and psychological distress, although related, have distinct correlates and different implications in the family context. 相似文献

Research on group identification has shown it to be a surprisingly weak predictor of intentions to take large‐scale social action. The weak links may exist because researchers have not always examined identification with the type of group that is most relevant for predicting action. Our focus in two studies (one in Romania and one in Australia, both Ns = 101) was on opinion‐based groups (i.e. groups formed around shared opinions). We found that social identification with opinion‐based groups was an excellent predictor of political behavioural intentions, particularly when items measuring identity certainty were included. The results provide clear evidence of the role of social identity constructs for predicting commitment to social action and complement analyses of politicised collective identity and crowd behaviour.

Self-reported and measured weight and height of 234 Croatian girls in Grades 5, 8, and 11 were used to explore the validity of these measures for calculating Body Mass Index. For both weight and height, the correlations between self-reported and measured values were over .93. Overweight girls underreported their weight and overreported their height. 相似文献

In 2005 Pedersen and Surburg reported that stimulant medications reduced the lower extremity response times of 16 boys with Attention-Deficit/Hyperactivity Disorder. However, as boys without ADHD and girls with and without ADHD were not studied, one cannot conclude that reported effects represent a medication effect unique to children with ADHD. An alternative hypothesis is presented: that stimulant medications produce an excitatory effect in the central nervous system by increased occupancy of postsynaptic dopamine receptors to reduce the lower extremity response times of children in general. Well-designed controlled clinical trials are needed to evaluate this hypothesis. 相似文献

Is it possible to learn to attend? The purpose of this article is to provide information about the development, administration, and contrast of an intervention program to improve selective and sustained attention in students from 5 to 19 years of age, all attending school, and with difficulties to learn the academic materials corresponding to their age. Two groups participated in the study: one with difficulties in selective attention and the other with difficulties in sustained attention. The group with selective attention difficulties was made up of 102 students, of whom 59 made up the experimental group and 43 the control group. The group of students with difficulties in sustained attention was made up of 106 students, of whom 58 participated as the experimental group and 48 as the control group. The results indicate that this kind of intervention (which combines visual therapy, cortical activation, and training with activity banks) is effective to improve attentional deficits, both at the level of selective attention and of sustained attention. 相似文献

The purpose of the present study is to analyse the relationship between sleep, burnout, and job strain in a sample of 316 healthy workers from various professional sectors. Multiple significant correlations between the principal sleep parameters, the dimensions of burnout, and job strain were found. The regression analyses show that sleep quality and various dimensions of job strain are significant predictors of several aspects of burnout. Sleep quality explains an even higher percentage of the variance in emotional exhaustion than the variance explained by more well-known variables such as job demands. Moreover, sleep quality interacts with aspects of job strain in its influence on the dimensions of burnout, although the exact relationship between these variables needs to be investigated in future longitudinal studies. Our results suggest that interventions to optimise sleep habits could prevent or alleviate burnout and could be a part of organisational work. 相似文献

Joint effect of dopaminergic genes on likelihood of smoking following treatment with bupropion SR. 总被引:1,自引:0,他引:1

OBJECTIVE: To determine the relationship between joint variation in 2 dopaminergic genes and the likelihood of nonsmoking following treatment with bupropion sustained release (SR). DESIGN: Three hundred twenty-three participants in a bupropion SR smoking cessation effectiveness trial with 12-month follow-up were genotyped for variants of dopamine receptor gene DRD2 and dopamine transporter SLC6A3. MAIN OUTCOME MEASURES: Self-reported 7-day point prevalence of nonsmoking. RESULTS: Neither genotype alone was associated with 7-day point-prevalent nonsmoking at the 12-month follow-up. However, in the presence of the DRD2 A1 allele, SLC6A3 status was significantly associated with the likelihood of nonsmoking at the 12-month follow-up (individuals with DRD2 A1+ and SLC6A3 9- were more likely to be smoking). In the absence of the DRD2 A1 allele, the association between SLC6A3 status and nonsmoking was nonsignificant. CONCLUSION: Although these results are suggestive, a more compelling test is needed of the hypothesis that dopaminergic gene interaction underlies, in part, the likelihood of smoking following treatment with bupropion SR. Most likely this will come from larger studies involving prospective randomization to treatment based on genotype. 相似文献
