This study sought to provide a more rigorous prospective test of two cognitive vulnerability models of depression with longitudinal data from 496 adolescent girls. Results supported the cognitive vulnerability model in that stressors predicted future increases in depressive symptoms and onset of clinically significant major depression for individuals with a negative attributional style, but not for those with a positive attributional style, although these effects were small. This model appeared to be specific to depression, in that it did not predict future increases in bulimia nervosa or substance abuse symptoms. In contrast, results did not support the integrated cognitive vulnerability self-esteem model that asserts stressors should only predict increased depression for individuals with a confluence of negative attributional style and low self-esteem, and this model did not appear to be specific to depression. 相似文献

Invertebrates are valuable models for increasing our understanding of the effects of ethanol on the nervous system, but most studies on invertebrates and ethanol have focused on the effects of ethanol on locomotor behavior. In this work we investigate the influence of an acute dose of ethanol on appetitive olfactory learning in the honey bee (Apis mellifera), a model system for learning and memory. Adult worker honey bees were fed a range of doses (2.5%, 5%, 10%, or 25%) of ethanol and then conditioned to associate an odor with a sucrose reward using either a simple or differential conditioning paradigm. Consumption of ethanol before conditioning significantly reduced both the rate of acquisition and the asymptotic strength of the association. Honey bees also exhibited a dose dependent reduction in arousal/attention during conditioning. Consumption of ethanol after conditioning did not affect recall 24h later. The observed deficits in acquisition were not due to the affect of ethanol on gustatory sensitivity or motor function. However, honey bees given higher doses of ethanol had difficulty discriminating amongst different odors suggesting that ethanol consumption influences olfactory processing. Taken together, these results demonstrate that an acute dose of ethanol affects appetitive learning and olfactory perception in the honey bee. 相似文献

For several decades, obesity has been a major health concern within the general population of the United States as well as
within the unique military population. Unlike the civilian sector, military service requires individuals to meet weight and
body fat standards. In order to assist overweight military personnel return to standards, Tripler Army Medical Center initiated
the LE3AN Program. LE3AN is a one-week, day-treatment, cognitive-behavioral weight management program coupled with 12 months of weekly follow-up.
Baseline data was collected on 387 consecutive participants. Despite physical fitness training and required standards in each
military service, the average BMIs for men and women were in the obese range, with male participants’ BMIs significantly higher
than women’s (34.3 vs 31.9, p<.005). One year outcome data was collected from 167 participants, i.e. 43.2% of treatment initiators. Among participants
who completed treatment, men maintained a 6.56% loss of their initial weight while women maintained a 7.35% loss. Over a quarter,
26.6%, of those who started the program (but did not complete it) maintained at least a 5% weight loss at one year, while
61.6% of treatment completers maintained 5% weight losses.

Effects of classroom context on university students’ judgments about cheating: mediating and moderating processes 总被引:2,自引:1,他引:1

Hypothetical vignettes were used to examine the effects of classroom context variables (pedagogical quality and classroom
goal structure) on undergraduate (study 1) and graduate (study 2) students’ judgments about cheating. Consistent with attribution
theory and previous findings, poor (versus good) pedagogy and performance (versus mastery) goals structures resulted in more
teacher blame and less student blame for cheating, and cheating was rated as more acceptable and more likely in these situations.
Participants’ own prior cheating history but not their experience as a classroom teacher also affected these judgments. Relations
between classroom context variables and assigned blame for cheating were mediated by students’ assessments of the fairness
of the classroom situation. 相似文献

Hearing loss is a common sensory deficit and more than 50% of affected individuals have a genetic etiology. The discovery
of 40 genes and more than 100 loci involved in hearing loss has made genetic testing for some of these genes widely available.
Genetic services for deafness are also being sought more often due to the early identification of hearing loss through newborn
screening services. The motivations for pursuing genetic testing, and how genetic services are provided to the client may
differ among individuals. Additionally, information obtained through genetic testing can be perceived and used in different
ways by parents of deaf children and deaf adults. This study aimed to follow up on focus group studies published earlier with
a quantitative survey instrument and assess the preference of consumers for provision of genetic services. We conducted a
national survey of hearing and deaf parents of children with hearing loss and of deaf adults. Data was compared and analyzed
by hearing status of the participant, their community affiliation and the genetic testing status using nominal logistic regression.
Consistent with our focus group results, the survey participants thought that a genetic counselor/geneticist would be the
most appropriate professional to provide genetics services. Statistically significant differences were noted in the preferred
choice of provider based on the genetic testing status. Parents preferred that genetic evaluation, including testing, occur
either immediately at or a few months after the audiologic diagnosis of hearing loss. This data should help providers in clinical
genetics keep patient preferences at the helm and provide culturally competent services. 相似文献

Information was gathered by means of a questionnaire survey and interviews from a group of patients (N = 17) and health professionals (N=13) working within a stroke unit, concerning the emotional needs of patients and and their relatives and how staff responded to these needs. Although most of the staff had received some training or information about counselling and felt that their interactions with patients often involved an element of counselling, there was strong support for separate specialised counselling services to deal with psychological problems suffered by both patients and their relatives. Patients rated assistance with personal and emotional worries and advice about physical problems as equally useful. A strong need for a counselling service in some form or other was expressed by patients. Neither the level of the patients' social support nor the presence or absence of aphasia, however, predicted the strength of interest expressed. It is concluded that specialised psychological help could be useful in various ways for both in- and out-patients and for their families. 相似文献
