This literature review describes the physical activity behavior of adults with mental retardation consistent with the U.S. Surgeon General's recommendation of 30 minutes of moderate intensity physical activity on 5 or more days per week. The proportion of participants achieving this criterion ranges from 17.5 to 33%. These data are likely to be generous estimates of activity as individuals included in physical activity studies to date have been relatively young and healthy volunteers with mild to moderate limitations. Major sources of physical activity were walking and cycling for transport, chores and work, dancing, and Special Olympics. There is a pressing need to conduct studies using appropriately powered representative samples and to validate measures that assess physical activity less directly; including methodologies in which proxy respondents are used. Accurate information about existing patterns of behavior will enhance the development of effective strategies to promote physical activity among persons with mental retardation. 相似文献

Evidence of Poor Planning in Children with Attention Deficits 总被引:1,自引:0,他引:1

This study examined the planning performance of children with attention deficits, and also investigated the possible interactions
between inattention and anxiety in the performance of executive function tasks. A group of 98 children (grades 4 and 6), derived
from an initial group of 550, were assigned to an attention difficulties group (AD) and a control group (n = 49 each) based on their scores on a variety of cognitive attention measures and teacher scales of attention and hyperactivity.
The two groups were matched on age, gender, parental education, non-verbal and verbal ability. They were compared on Crack-the-Code
(C-t-C) action-planning task, embedded and ambiguous figures and Theory of Mind tasks. Analyses indicated that the failure
of AD children on cognitive performance measures is linked to planning impairments. The co-occurrence of anxiety, in turn,
did not interact with inattention to affect planning performance differentially. Implications of these findings for the current
discussion about the cognitive and emotional processes underlying impaired performance among children with attention deficits
on executive control tasks are discussed. 相似文献

The current study examined the unique and interactive associations of callous–unemotional (CU) traits, impulsive and premeditated aggression with startle modulation to violent films. Eighty-five participants (Mage = 20.52) at differential risk of CU traits, selected from a sample of 1105 young adults, participated in the physiological experiment. Startle eye-blink responses to acoustic probes were recorded during violent, comedy and neutral films. Self-report ratings of valence and arousal were also collected. Findings from regression analysis documented that CU traits were associated with diminished startle potentiation to violent films, whereas impulsive aggression was associated with increases in startle potentiation. Further, the negative association between CU traits with startle potentiation, valence, and arousal ratings to violent films was moderated by impulsive aggression. At the group level, individuals high on impulsive aggression without CU traits were the ones showing the highest levels of startle potentiation to violent films, and scored on the opposite extreme compared to individuals high on both CU traits and impulsive aggression. 相似文献

The current study aimed to identify heterogeneous groups of adolescents differing on their levels of conduct problems (CP) and callous-unemotional (CU) traits, and compare them on startle reactivity to emotional videos (violent/erotic) during young adulthood. A Latent Profile Analysis, conducted among a longitudinal sample of 2306 adolescents, provided evidence for the existence of heterogeneous CP and CU subgroups (i.e., CP-only, CU-only, and CP+CU groups). Three years later, 82 young adults (Mage?=?19.95), randomly selected from the identified groups, participated in an experiment assessing their startle eye-blink responses during violent, erotic and neutral video scenes. Self-report ratings of fear, valence and arousal to affective scenes were also collected. Findings suggested that adolescents high on CP and low on CU traits showed high startle potentiation when viewing violent scenes during young adulthood, while those high on both CP and CU traits showed diminished startle reactivity to violent stimuli. Individuals high on CU traits without CP showed similar startle reactivity to controls. Further, the findings indicate that startle potentiation to violent stimuli can be a reliable physiological marker to distinguish antisocial individuals with and without CU traits. The finding that the CU only group was not differentiated from the control group on startle reactivity when viewing violent stimuli might explain their lower likelihood of engaging in antisocial behavior. 相似文献

The five-factor inventory (FFI) is a commonly used personality test based on the NEO-personality inventory revised. It has been translated into several languages and validated in a number of countries. Using a sample of 1204 individuals, the present study evaluates the psychometric properties and factor structure of the Greek FFI and provides normative information for its use with Greek populations. Convergent validity is also assessed by studying the relationship between the five scales of the FFI and the Brief Symptom Inventory. Results show that although the factor scales had acceptable internal consistency, they were highly intercorrelated. Exploratory factor analyses failed to reproduce the appropriate factor structure, yielding instead numerous fragments of the five dimensions. Confirmatory factor analyses also failed to lend support to the five factor model of personality as measured by this instrument. Based on these results, the use of the instrument is recommended only with serious caution in this cultural context. Further research ought to decipher whether the failures to reproduce the five factor model using the FFI in this and other cultures represents a challenge to the universality of the theory, or merely a shortcoming of the specific instrument. 相似文献

Diabetes mellitus type 2 (DM type 2) is associated with depressive symptomatology and intermittent hyperfunction of the hypothalamic-pituitary-adrenal (HPA) axis. DM type 2 is also accompanied by increased tissue levels of angiotensin II (Ang II), which stimulates the HPA axis through the Ang II type 1 receptors (AT1). We investigated the effect of candesartan, an angiotensin receptor blocker (ARB) that crosses the blood brain barrier, on the activity of the HPA axis and on the affect of 17 patients with DM type 2, aged 40-65 years, who were treated with 4 mg/day candesartan per os for at least 3 months. Before and after candesartan administration, a corticotropin-releasing hormone (CRH) stimulation test and psychological tests were performed. In response to hCRH, time-integrated secretion of ACTH was not altered by candesartan administration, however, the cortisol response was decreased significantly compared to baseline (mean +/- SEM, 2327 +/- 148.3 vs. 1943 +/- 131.9 microg/dl, P = 0.005) suggesting reduced sensitivity of the adrenals to ACTH. In parallel, there was a significant improvement in interpersonal sensitivity (0.91 +/- 0.16 vs. 0.70 +/- 0.15, P = 0.027) and depression scores (0.96 +/- 0.15 vs. 0.71 +/- 0.10, P = 0.026). We suggest that candesartan resets the HPA axis of patients with DM type 2 and improves their affect. 相似文献

We propose that the earliest neuropsychological detection of Alzheimer’s disease (AD) can be informed by current views about
the neuropathogenesis of AD and cognitive models of memory and its neurobiological substrates. The primary impairment in early
AD is encoding/consolidation, resulting from medial temporal lobe (MTL) pathology. On theoretical and empirical grounds, paired
associate learning (PAL) appears to be the ideal paradigm for detecting MTL dysfunction in early AD. It has not been embraced
as a test of choice, however, and this critical review discusses why the paradigm may have not fulfilled its potential. We
suggest that a new PAL variant, ‘associate-recognition’, may prove to be clinically efficacious. 相似文献

Disclosure rates of child sexual abuse (CSA) to both social supports and law enforcement are concerningly low, although more research is needed to understand factors that impact disclosure. Thus, the present study examined rates of informal (i.e., to a social support) and formal (i.e., to law enforcement) disclosure of CSA, as well as victims' self-reported experiences with telling others about their own abuse and their perceptions of the overall advantages and disadvantages of disclosure. In all, 76 undergraduate women (who collectively experienced 105 instances of abuse) participated in a semi-structured interview regarding their history of CSA. Results revealed that approximately 50% of cases involved the victim informally disclosing, and only 10% of cases being formally disclosed to authorities. The quantitative and qualitative data shed light on a number of factors that lead victims to not disclose, as well as the identification of factors that may promote a victim to share their abuse with others. The implications for improved prevention and responses to CSA disclosure are discussed. 相似文献

While the efficacy of couple therapy has been repeatedly demonstrated, most distressed couples do not seek treatment. To improve reach and overcome barriers to therapy, Integrative Behavioral Couple Therapy (IBCT) was translated into a web-based program, OurRelationship (OR). While both IBCT and OR have been shown to improve relationship and individual functioning, the goal of the present study was to compare the relative cost effectiveness of these two treatment modalities. In IBCT, 74% of couples experienced reliable improvement, compared to 55% of couples in OR. Within-group Cohen's d effect sizes during treatment for relationship satisfaction were d = 0.87 for IBCT and d = 0.96 for OR. Relative cost effectiveness analyses revealed that even at the highest expense estimates for OR and the lowest expense estimates for IBCT, OR was more cost effective in creating reliable improvement once at least 229 couples were served and was more cost effective in creating large-size effects once at least 153 couples were served. Cost-effectiveness increases for both IBCT and OR as more couples are served; however, this cost savings occurs at a much more rapid rate for OR. These findings demonstrate that despite higher initial development costs, Internet programs are a cost-effective option for dissemination either as a stand-alone service or as an initial intervention in a stepped care model with more intensive in-person services. 相似文献
