Mothers of children with attention-deficit/hyperactivity disorder (ADHD) are at increased risk for an ADHD diagnosis themselves,
which is likely associated with impairments in parenting. The present study utilized a multi-method assessment of maternal
ADHD and parenting to examine the extent to which maternal ADHD symptoms are associated with maladaptive parenting. Participants
included 70 6–10 year old children with DSM-IV ADHD and their biological mothers. Results suggested that mothers with higher
levels of ADHD symptoms reported lower levels of involvement and positive parenting and higher levels of inconsistent discipline.
During observed parent–child interactions, maternal ADHD symptoms were negatively associated with positive parenting, and
positively associated with negative parenting and repeated commands before giving the child an opportunity to comply. Given
prior research suggesting that maladaptive parenting behaviors are risk factors for the later development of conduct problems
among children with ADHD, these findings have important clinical implications for family-based assessment and treatment of
ADHD. 相似文献

Patients with schizophrenia have disproportionately high rates of emergency medical service use, likely contributing to the high cost this illness places on society. The aim of this study was to examine the impact of a theory-based, behavioral intervention on immediate and long-term use of emergency medical services. Older patients with schizophrenia (n=240) were randomized to receive either a behavioral, skills-building intervention known as Functional Adaptation and Skills Training (FAST) or a time-equivalent attention-control condition (AC). Logistic regression analyses indicated that AC participants were nearly twice as likely to use emergency medical services in general (OR=2.54; p=0.02) and emergency psychiatric services in particular (OR=3.69; p=0.05) during the active intervention phase of the study. However, there were no differences between the interventions in terms of emergency service use during the long-term follow-up phase of the study (i.e., 6-18 months post-baseline). The FAST intervention appears efficacious for reducing the short-term risk of using emergency medical services. However, the long-term efficacy of the FAST intervention appears less clear. Future studies may want to provide more powerful maintenance sessions to encourage continued use of skills in patients' real-world settings. 相似文献

The present experiment studied choice response context effects on the programming of response sequences using behavioural and electrophysiological methods. Participants were asked to produce responses differing in sequence length (1-key vs. 3-key responses) with either their left or right hand in a choice reaction time (RT) task. The choice response context was manipulated by a blocked or mixed execution of 1-key and 3-key responses. A sequence length effect on RT was observed in the blocked but not in the mixed condition. The time course of the lateralized readiness potential indicates a motoric locus of the sequence length effect, suggesting that the response hand is activated before the entire motor program is established. 相似文献

Adverse impact evaluations often call for evidence that the disparity between groups in selection rates is statistically significant, and practitioners must choose which test statistic to apply in this situation. To identify the most effective testing procedure, the authors compared several alternate test statistics in terms of Type I error rates and power, focusing on situations with small samples. Significance testing was found to be of limited value because of low power for all tests. Among the alternate test statistics, the widely-used Z-test on the difference between two proportions performed reasonably well, except when sample size was extremely small. A test suggested by G. J. G. Upton (1982) provided slightly better control of Type I error under some conditions but generally produced results similar to the Z-test. Use of the Fisher Exact Test and Yates's continuity-corrected chi-square test are not recommended because of overly conservative Type I error rates and substantially lower power than the Z-test. 相似文献

We investigated the social implications of signing an informed consent form (ICF) on participant behavior. ICF research fails to consider that the decision to participate in research is a process that occurs in a social and cultural context. Understanding the meaning of giving consent in this social context is critical. In separate experiments, we found significantly greater agreement to return to complete a study and persistence at a task in participants who signed the ICF versus those who did not. Signing the ICF may be putting participants at risk of induced compliance with study protocols, rather than empowering them to withhold consent or withdraw. Future research should investigate the psychosocial factors affecting participants' decision making in the informed consent process. 相似文献

The violent video game literature has previously not extended to the domain of violence against women. The current investigation tested the effects of exposure to sex-typed video game characters versus images of professional men and women on judgments and attitudes supporting aggression against women. Results showed experimental effects of short-term exposure to stereotypical media content on sexual harassment judgments but not on rape myth acceptance. A significant interaction indicated that men exposed to stereotypical content made judgments that were more tolerant of a real-life instance of sexual harassment compared to controls. Long-term exposure to video game violence was correlated with greater tolerance of sexual harassment and greater rape myth acceptance. This data contributes to our understanding of mass media’s role in socialization that supports violence against women. 相似文献

Self-enhancement is the biasing of one’s view of oneself in a positive direction. The brain correlates of self-enhancement remain unclear though it has been reported that the medial prefrontal cortex (MPFC) may be important for producing self-enhancing responses. Previous studies have not examined whether the neural correlates of self-enhancement depend on the particular domain in which individuals are enhancing themselves. Both moralistic and egoistic words were presented to participants while transcranial magnetic stimulation (TMS) was applied to the MPFC, precuneus or in a sham orientation. Participants were asked to make decisions as to the words describing themselves, some of which were positive and some of which were negative. It was found the MPFC TMS significantly disrupted egoistic self-enhancement when TMS was delivered to the MPFC. Judgments involving moralistic words were not influenced by TMS. These data provide further evidence that MPFC is involved in self-enhancement, and that the role of MPFC may be selective in this regard. 相似文献

This study investigated the influence of changing socio-historical conditions on personal goals in young adulthood. It was
hypothesized that socio-historical changes related to individualization have resulted in shifts in goal pursuit. Participants
from three birth cohorts reconstructed their important goals when they were 20 years old. Members of the oldest cohort were
born between 1920 and 1925. Members of the middle cohort were born between 1945 and 1950. Members of the youngest cohort were
born between 1970 and 1975. Goal content, the degree to which goals were perceived as being shared by members of the same
cohort (social sharedness), perceived control over goal attainment, success in attainment, and life satisfaction at age 25
were measured in a retrospective study. Results show consistent shifts over time. Whereas members of older cohorts mentioned
goals related to classical developmental tasks, members of younger cohorts mentioned more individualistic, self-related goals
and goals related to education. The processes through which goal pursuit influenced life satisfaction also changed. Perceived
social sharedness of goals was a direct predictor of life satisfaction for the oldest cohort. For the younger cohorts, perceived
control over goal attainment influenced success which in turn influenced life satisfaction. These changes support the contention
that developmental tasks and processes are historically variant. 相似文献
