This study was an investigation of awareness, cognitions, and psychosocial and educational needs related to genetic counseling
and testing among Latinas and non-Latina whites at increased risk for having a BRCA1/2 mutation. Sixty-three Latina and eighty-four non-Latina white women completed telephone surveys employing a mixture of quantitative
and qualitative questions assessing awareness, benefits, risks, barriers, and genetic counseling communication preferences
regarding BRCA1/2 testing. Among participants who had not previously had genetic counseling/testing, 56.9% of Latinas (29/51) and 34.8% of
non-Latina white participants (24/69) were unaware of the availability of BRCA1/2 testing. In multivariate logistic regression analysis, Latina ethnicity was the only statistically significant independent
factor associated with lack of awareness (OR = 0.42; 95% CI = 0.19–0.35). No appreciable differences were noted between ethnic
groups regarding perceived benefits of BRCA1/2 testing or desired genetic counseling topics. These findings underscore the importance of increasing awareness of cancer
genetic counseling and genetic testing among both Latina and non-Latina white populations. 相似文献

Objectives
Perfectionism is thought to energise high quantities of motivation; however, its wider influence on the quality of the motivation exhibited by athletes is less clear. The purpose of this study was to examine the multivariate and univariate relationship between multidimensional perfectionism (perfectionistic concerns and perfectionistic striving) and perceived psychological need thwarting. Perfectionistic concerns was assessed via sub-dimensions of socially prescribed perfectionism, concern over mistakes, doubts about actions, parental pressure and coach pressure. Perfectionistic striving was assessed via sub-dimensions of self-oriented perfectionism, other-oriented perfectionism, personal standards and a need for organisation.Design
A cross-sectional, survey-based design was employed.Method
One hundred and ninety-nine junior sports participants were recruited from after-school sports clubs and completed measures of multidimensional perfectionism and psychological need thwarting.Results
Canonical correlation analyses revealed that higher levels of perfectionistic concerns were associated with higher levels of perceived psychological need thwarting. Analogously, lower levels of perfectionistic striving were associated with lower levels of perceived psychological need thwarting. Regression analyses revealed that the relative importance of individual sub-dimensions of perfectionism differed depending on the facet of psychological need thwarting being assessed. Perceptions of parental pressure, coach pressure and concern over mistakes emerged as especially important.Conclusion
Overall, the findings indicate that while perfectionism may contribute to high levels of behavioural investment, it may also impoverish the necessary support required for the fulfilment of psychological needs. 相似文献274.
Puberty is a critical risk period for binge eating and eating disorders characterized by binge eating. Previous research focused almost entirely on psychosocial risk factors during puberty to the relative exclusion of biological influences. The current study addressed this gap by examining the emergence of binge eating during puberty in a rat model. We predicted that there would be minimal differences in binge eating proneness during pre-early puberty, but significant differences would emerge during puberty. Two independent samples of female Sprague-Dawley rats (n = 30 and n = 36) were followed longitudinally across pre-early puberty, mid-late puberty, and adulthood. Binge eating proneness was defined using the binge eating resistant (BER)/binge eating prone (BEP) model of binge eating that identifies BER and BEP rats in adulthood. Across two samples of rats, binge eating proneness emerged during puberty. Mixed linear models showed little difference in palatable food intake between BER and BEP rats during pre-early puberty, but significant group differences emerged during mid-late puberty and adulthood. Group differences could not be accounted for by changes in nonpalatable food intake or body weight. Similar to patterns in humans, individual differences in binge eating emerge during puberty in female rats. These findings provide strong confirming evidence for the importance of biological risk factors in developmental trajectories of binge eating risk across adolescence. 相似文献

In this brief report, the source of firearms used in adolescent suicides was examined using data from the National Violent Injury Statistics System, the pilot to the CDC's National Violent Death Reporting System, a uniform reporting system for violent and firearm-related deaths. Data represent the 63 firearm suicides among youth (<18 yrs) that occurred in 2001 or 2002 in one of four states (CT, ME, UT, WI) or two metropolitan counties (San Francisco, CA; Allegheny County, PA). Four-fifths of the suicides took place in the decedents' homes, and--when the firearm owner was known--most of the firearms were owned by parents. Findings replicate results from previous research and highlight the importance of limiting youth access to firearms. 相似文献

This paper reviews theory and past research concerning nonlinear relationships between personality tests and job performance. We compare linear and nonlinear regression models for each of the 32 Occupational Personality Questionnaire (OPQ32i) scales using job performance as the criterion variable. We evaluate linear, quadratic, and cubic relationships between personality and job performance by calculating changes in R (ΔR) between the linear and nonlinear models. We use 3 decision rules of varying levels for ΔR and divide a large sample randomly into 2 samples to cross‐validate any nonlinear effects found. Few scales exhibited nonlinearity and the magnitude of the departures from linearity were small. 相似文献

In order to understand how age, culture, and problems in motor coordination impact the performance of activities of daily living, we used focus groups and in-depth interviews with Australian and Canadian parents to examine activities of daily living of younger (5-7 years of age) and older (8-9 years of age) children with and without DCD. By comparison with their typically developing age group, children with DCD had more difficulty with dressing, personal hygiene, and eating skills. Difficulties with postural control and fine-motor skills were reported to contribute to poorer performance of activities of daily living. As expected, competence in the performance of activities of daily living improved in the older children with and without DCD and there were few differences in the performance of daily living tasks between typical children in Australia and Canada. Overall, the motor difficulties of children with DCD had a significant impact on performance of a wide range of daily activities. 相似文献

It is well-known that classical models of belief are not realistic representations of human doxastic capacity; equally, models
of actions involving beliefs, such as decisions based on beliefs, or changes of beliefs, suffer from a similar inaccuracies.
In this paper, a general framework is presented which permits a more realistic modelling both of instantaneous states of belief,
and of the operations involving them. This framework is motivated by some of the inadequacies of existing models, which it
overcomes, whilst retaining technical rigour in so far as it relies on known, natural logical and mathematical notions. The
companion paper (Towards a “sophisticated” model of belief dynamics. Part II) contains an application of this framework to the particular case of belief revision.

This study examined the influence of feminist attitudes on self-objectification, habitual body monitoring, and body dissatisfaction in middle age and older women. The participants were 138 European American heterosexual women ranging in age from 40 to 87 years old. Consistent with previous research, self-objectification and habitual body monitoring were positively correlated with body dissatisfaction and, self-objectification and habitual body monitoring remained stable across the lifespan. While age did not moderate the relationship between self-objectification and body dissatisfaction, age was found to moderate the relationship between habitual body monitoring and body dissatisfaction such that the relationship was smaller for older women than for middle-aged women. Interestingly, feminist attitudes were not significantly correlated with body dissatisfaction, self-objectification, or habitual body monitoring, and endorsement of feminist attitudes was not found to moderate the relationship between self-objectification or habitual body monitoring and body dissatisfaction. Potential implications for older women are discussed. 相似文献

This article summarizes main results of studies on forensic psychiatric court reports on 166 men who had been persecuted between 1963 and 1991 for a sexual offence leading to the death of the victim. Comparing perpetrators with a single victim and those with multiple victims we found similar results as in two previous studies with smaller samples: Multiple sexual homicide perpetrators showed more often sexual sadism and other paraphilias, as well as antisocial, schizoid and sadistic personality disorders. Follow-up data from the federal criminal records could be obtained for 139 offenders. Ninety perpetrators had been released after a mean detention of 12.2 years, whereas the 49 offenders who were still in prison or forensic psychiatric hospitals had been detained for a mean period of 20.6 years. The non-released offenders showed more often paraphilias as well as antisocial and sadistic personality disorders than the released perpetrators. Paraphilias and antisocial personality traits are empirically well proven risk factors for criminal recidivism with sexual reoffences. In addition, the non-released sexual homicide perpetrators had higher scores in all applied risk assessment instruments (PCL-R, HCR-20, SVR-20, Static-99). Among the released offenders only 1.1% (n=1) reoffended with a completed homicide and 2.2% (n=2) with attempted homicide. The recidivism rates with sexual and other violent reoffences in this sample of sexual homicide perpetrators were similar to those in a large meta-analysis on recidivism in sexual offenders by Hanson and Morton-Bourgon (4). Since well established risk factors had apparently been “used-up” for the decisions about release or non-release, in the follow-up data about the released offenders only age at the sexual homicide and age at the time of release were found as risk factors for recidivism with any violent (sexual or non-sexual) reoffence, i.e. the younger the offender at the time of the homicide and the younger at the time of release, the more likely is the risk of violent reoffending. 相似文献
