Poor socioeconomic status and African American (AA) ethnicity contribute to an increased risk of obesity for many inner city children. One hundred and forty six AA children and 108 AA parents attending an inner city health fair completed surveys regarding perceptions of their own (or their child's) weight and the impact of weight on health. The children were measured and their body mass indexes were calculated. Thirty-seven percent of the child respondents (n = 52) were at risk of overweight or overweight; of these, 67% perceived themselves as normal weight, and 77% thought their weight was healthy. Weighing more was felt to be healthy by 17% of children and 29% of parents. Of 39 parents whose children were at risk of overweight or overweight, 68% felt their child's weight was normal and 80% thought it was healthy. These results suggest that inner city AA children and their parents often do not recognize being overweight or the health implications of being overweight. 相似文献

From mid-October 2001 through the end of November 2001, we collected fairly large sets of questionnaires from undergraduates at three public universities (Albany, NY, n = 507, Augusta, GA, n = 336, Fargo, ND, n = 526 ) to assess rate of acute stress disorder (ASD) and level of ASD symptoms following the September 11th attacks, rate of current posttraumatic stress disorder (PTSD) and level of PTSD symptoms, and current level of depressive symptoms resulting from the September 11th attacks. We also gathered information on exposure to media coverage of the attacks, connectedness to the World Trade Center (WTC) and personnel there, and degree of engagement in reparative acts such as giving blood, attending vigils. We found higher levels of ASD, ASD symptoms, PTSD and PTSD symptoms as a function of geographical proximity to New York City (and within the Albany site, proximity of students' homes) and gender. Exposure (hours of TV watched) was a predictor in some instances as was connectedness to WTC victims. ASD symptoms were the strongest predictor of subsequent PTSD symptoms. Path models accounted for over 60% of the variance in PTSD symptoms. 相似文献

Correcting distorted perception of sleep in insomnia: a novel behavioural experiment? 总被引:5,自引:0,他引:5
Patients with primary insomnia overestimate their sleep onset latency (SOL) and underestimate their total sleep time (TST). The present study aimed to test the utility of a novel behavioural experiment designed to correct distorted perception of sleep among patients diagnosed with primary insomnia. Individuals with primary insomnia were asked to wear an actigraph and keep a sleep diary for three nights. On the following day, half were shown the discrepancy between the data recorded on the actigraph and their sleep diary (Shown-Discrepancy Group), the other half were not shown the discrepancy (No-Demonstration Group). Participants were then asked to wear the actigraph and keep a sleep diary for three further nights. Following the behavioural experiment, the Shown-Discrepancy Group estimated their SOL more accurately and reported less anxiety and preoccupation about sleep compared to the No-Demonstration Group. The theoretical and clinical implications of these findings are discussed. 相似文献

A stress management programme for Crohn's disease 总被引:3,自引:0,他引:3
The present study was designed to assess the effectiveness of techniques of behavioural assessment and treatment of Crohn's disease (CD). On the assumption that stress events have a pronounced influence on the life of Crohn's patients, we proposed stress management treatment. This is intended to control stress and improve patients' personal and social competence. Forty-five patients with Crohn's disease were randomly assigned to one of three treatment groups, two experimental groups: stress management and self-directed stress management, and a control group: conventional medical treatment. The subjects underwent eight individual sessions which were specific to each condition. All subjects completed symptom monitoring diaries. The subjects who received training in stress management experienced a significant post-treatment reduction of tiredness (P < 0.1), constipation (P < 0.1), abdominal pain (P < 0.5) and distended abdomen (P < 0.5). The subjects who received training in self-directed stress management experienced a significant reduction in tiredness (P < 0.1) and abdominal pain (P < 0.5). No significant changes were observed in symptomatology in the conventional medical treatment group. Similar results were obtained in the 12 month follow-up. 相似文献

Given a hint from Lang, Bradley, and Cutbert's (1997) defense cascade, two cognitive processes, instead of passive versus active behavioral coping, which seem to have differential effects on the provocation of vascular- versus cardiac-dominant reaction pattern during mental stress were advocated: attention (Attent) versus unpleasant affect (UnplAff). Based on this notion the Attention-Affect Check List (AACL) was developed as a self-report measure. In addition, items on uncontrollability (Uncontr) were prepared for the purpose of checking whether heightened Attent and UnplAff are accompanied by alterations in Uncontr. Two hundred and eighty-four students underwent two kinds of mental stress, which seemed to specifically heighten Attent and UnplAff. Four factors with four items each were extracted from the AACL item pool: concentrated and allocated Attent, UnplAff, and pleasant affect. Also, one factor with four items was extracted from the Uncontr item pool. For both the mental stresses, each scale, although very brief, had quite reasonable alpha reliability. Accountability of each scale for the total variance was reasonably high. Some problems are discussed in relation to the validity of AACL. 相似文献

Testing the concurrent and predictive relations among articulation accuracy, speech perception, and phoneme awareness 总被引:2,自引:0,他引:2
The relations among articulation accuracy, speech perception, and phoneme awareness were examined in a sample of 97 typically developing children ages 48 to 66 months. Of these 97 children, 46 were assessed twice at ages 4 and 5 years. Children completed two tasks for each of the three skills, assessing these abilities for the target phoneme /r/ and the control phoneme /m/ in the word-initial position. Concurrent analyses revealed that phoneme-specific relations existed among articulation, awareness, and perception. Articulation accuracy of /r/ predicted speech perception and phoneme awareness for /r/ after controlling for age, vocabulary, letter-word knowledge, and speech perception or phoneme awareness for the control phoneme /m/. The longitudinal analyses confirmed the pattern of relations. The findings are consistent with a model whereby children's articulation accuracy affects preexisting differences in phonological representations and, consequently, affects how children perceive, discriminate, and manipulate speech sounds. 相似文献

Previous experiments investigating the influence of rumination on negative affect have often manipulated the timing and content of rumination, which may be problematic as rumination is phenomenologically experienced as uncontrollable. In the present experiment, rumination was not manipulated, but measured as an individual tendency before the experiment. Furthermore, it was tested whether defensiveness would reduce the higher degree of negative affect often associated with rumination. Fifty-six participants completed questionnaires measuring rumination and defensiveness and participated in a phrase completion task, rating negative affect before and after the task. Correlational analyses showed that rumination was positively associated (p < 0.05) with affect responses (r range = 0.35-0.61), whereas defensiveness was negatively associated with affect responses (r range =-0.27-0.32). Four groups of high and low rumination and defensiveness scorers were created using median splits. An ANOVA showed that scoring high on defensiveness did not reduce the negative affect experienced by high ruminating participants. 相似文献

Background: Women who experience intimate partner violence (IPV) report greater stress and negative health consequences than nonabused women. Although an association between psychological stress and altered immune function has been shown, IPV studies have not investigated this relationship. Objective: This study explored the association of IPV with mental health symptoms and an immune marker to determine if posttraumatic stress disorder (PTSD) symptoms mediate the effect of IPV on pro-inflammatory (IFN-γ) cytokine levels. Methods: A cross-sectional, comparative design was used to compare 62 women with IPV and 39 nonabused women. Results: Mean IFN-γ values were higher in abused women and in women with current PTSD symptoms. There were no significant relationships with potential confounding variables that could provide an alternative explanation for the increase in production of proinflammatory cytokines. Conclusions: PTSD symptoms mediate the association between IPV and IFN-γ levels and may partially explain the association of mental health symptoms with physical health sequelae in IPV. 相似文献

Boredom is a common experience in healthy individuals and may be elevated in various neurological or psychiatric conditions. As yet, very little is known about the cognitive or neural bases of the subjective experience of boredom. We examined temporal perception and the temporal allocation of attention in healthy individuals reporting high- or low-levels of boredom. We found no difference in high- or low-boredom-prone individuals in the temporal allocation of attention, while individuals who experienced low-levels of boredom tended to underestimate time more so than high-boredom-prone individuals. Furthermore, high-boredom-prone individuals demonstrated higher error values when estimating time indicating that the subjective perception of the passage of time may be a critical component to the experience of boredom. 相似文献

Categorical perception of color is shown when colors from the same category are discriminated less easily than equivalently spaced colors that cross a category boundary. The current experiments tested various models of categorical perception. Experiment 1 tested for categorical responding in 2- to 4-year-olds, the age range for the onset establishment of color term knowledge. Experiment 2 tested for categorical responding in Himba toddlers, whose language segments the color space differently from the way in which the English language does so. Experiment 3 manipulated the conditions of the task to explore whether the categorical responding in Experiments 1 and 2 was equivalent to categorical perception. Categorical perception was shown irrespective of naming and was not stronger in those children with more developed color term knowledge. Cross-cultural differences in the extent of categorical perception were not found. These findings support universalistic models of color categorization and suggest that color term knowledge does not modify categorical perception, at least during the early stages of childhood. 相似文献
