Women with a personal or family history of breast or ovarian cancer are increasingly presenting for genetic cancer risk assessment (GCRA). To explore the personal and family impact of GCRA, four focus groups were conducted of women seen for risk assessment. Participants were 22 primarily non-Latina White women with a personal or family history of breast or ovarian cancer. Analysis of the data identified new themes related to balancing time to assimilate risk information with the need to make timely healthcare decisions, physicians’ lack of sufficient genetic knowledge, and concern for daughters regardless of the daughters’ age. Other themes related to protecting others, knowledge as empowerment, reassessing personal attribution of cancer risk, managing uncertainty, reappraising body image, and experiencing divergent family responses to communication of cancer risk and healthcare decisions. Understanding the personal and family impact of GCRA may enable genetics professionals to tailor their counseling efforts to better meet the needs of these women. Additional research is needed to extend these findings and identify interventions to support positive outcomes of GCRA. 相似文献

It is remarkably difficult for people with obesity to maintain a new lower weight following weight loss. The aim of the present study was to examine the immediate and longer-term effects of a new cognitive behavioural treatment that was explicitly designed to minimise this post-treatment weight regain. One hundred and fifty female participants with obesity were randomized to the new treatment, behaviour therapy (the leading alternative psychological treatment) or guided self-help (a minimal intervention). Both of the main treatments resulted in an average weight loss of about ten percent of initial weight whereas weight loss was more modest with guided self-help. The participants were subsequently followed-up for three years post-treatment. The great majority regained almost all the weight that they had lost with the new treatment being no better than the behavioural treatment in preventing weight regain. These findings lend further support to the notion that obesity is resistant to psychological methods of treatment, if anything other than a short-term perspective is taken. It is suggested that it is ethically questionable to claim that psychological treatments for obesity “work” in the absence of data on their longer-term effects. 相似文献

Repetitive and invariant behavior is a diagnostic feature of autism. We implemented a lag reinforcement schedule to increase response diversity for 6 participants with autism aged 6 to 10 years, 4 of whom also received prompting plus additional training. These procedures appeared to increase the variety of building-block structures, demonstrating that an intervention that includes differential reinforcement can increase response diversity for children with an autism spectrum disorder. 相似文献

Visual cues are known to be used by numerous animal taxa to gather information on quality and localisation of resources. Because
environmental lighting can interfere with the spectral features of visual cues, the specific characteristics of the colour
signals that promote forager decision and learning are still not known in the majority of insects (excepted in bees). We analysed
the effect of previous experience on the use of visual information by the wasp Venturia canescens, a parasitoid of pyralidae, in the context of host searching. These parasitoids search for hosts concealed in several fruit
species, so visual cues from the host microhabitat could play a key role in host finding. We also investigated the type of
visual cues on which wasps based their decision. We tested whether wasps are able to associate an achromatic cue (brightness)
or a chromatic one (hue, i.e. dominant wavelength and/or chroma) with the presence of hosts. Our results show that in the
context of host foraging, chromatic cues are more reliable than brightness in achieving the associative learning process.
Therefore, understanding the behavioural ecology of foraging should make use of the knowledge about the visual information
used. 相似文献

Based on existing research on social networking and information seeking, it was proposed that Facebook.com use could be conceptualized as serving two primary goals: passive social browsing (i.e., newsfeeds) and extractive social searching (i.e., friends' profiles). This study explored whether these categories adequately reflect Facebook use and whether they moderate physiological indicators of emotion. Thirty-six participants navigated Facebook.com while their on-screen activity and physiological responses associated with motivation and emotion were recorded. Results showed that the majority of screens encountered during Facebook use could be categorized as devoted to social browsing or social searching. Participants spent more time on social browsing than they spent on social searching. Skin-conductance data indicated that sympathetic activation diminished during the course of both social browsing and social searching. Facial EMG data indicated that participants experienced more pleasantness during the course of social searching than they experienced during social browsing. These results are discussed in terms of existing social-networking research and an evaluative space model of emotion. 相似文献

Direct and Indirect Aggression: Relationships as Social Context 总被引:1,自引:0,他引:1
The studies reported in this paper examined the effect of social context—target gender and target relationship—on reports of direct and indirect aggression. In Study 1, participants completed the Richardson Conflict Response Questionnaire (RCRQ; Richardson & Green, 2003 ), which measured their direct and indirect aggression behavior in response to anger. Participants also selected a relationship partner to complete the RCRQ with reference to their own (i.e., participants') behavior. In Study 2, participants completed the RCRQ with reference to their behavior in response to anger with a romantic partner, a same-sex friend, and an opposite-sex friend. In both studies, relationship with aggression target was an important determinant of aggression, with more direct aggression occurring in romantic relationships, and more indirect aggression occurring in friendship relationships. 相似文献

A personal construct counselling approach that we are using with young children is presented here, an approach based on the construct of “wellness”, a medium to promote the well-being of troubled children and their families. The case study we share with you shows a counselling intervention based on play, with experiments drawn from self-related construct systems of “making things better” rather than construct systems of “fixing things up”. We present a case study of a young girl grieving over the death of her father. Emphasis is placed on the relationship of trust between the child and the counsellor, to encourage experimentation with relationship experiences to help the child to reconstrue events outside the counselling context. Working hypotheses drawn from cognitive and emotional developmental research into young children are provided, and the subsequent investigations which guide our intervention. Suggestions for process and outcome research in this area are finally made. 相似文献

The authors propose an alternative conceptualization to the Strack, Werth, and Deutsch (2006) model. This alternative conceptualization considers how the forecasting of emotional outcomes linked to controlling or failing to control impulses affects self‐regulatory behavior. A set of future research questions is identified based on this conceptualization. The proposed model differs from that of Strack et al. (2006) by its focus on (a) affect, (b) impulse control (versus buying), and (c) deliberative processing linked to impulse control (or lack thereof). 相似文献

LOOKING GOOD, SOUNDING GOOD: FEMININITY IDEOLOGY AND ADOLESCENT GIRLS' MENTAL HEALTH 总被引:1,自引:0,他引:1

This study used a feminist psychodynamic developmental framework to test the hypothesis that internalizing conventional femininity ideologies in two domains—inauthenticity in relationships and body objectification—is associated with early adolescent girls' mental health. One hundred forty-eight eighth-grade girls completed measures of femininity ideology, self-esteem, depression, and demographic characteristics. In the first part of this study, we refined the Adolescent Femininity Ideology Scale originally developed by Tolman and Porche (2000) . In the second part, we used structural equation modeling to test models linking femininity ideology to mental health. Results revealed that body objectification, and to a lesser extent, inauthenticity in relationships, accounted for half of the variance in depression and over two-thirds of the variance in self-esteem in a critical period of development for adolescent girls. The importance of a feminist psychodynamic developmental framework for identifying and understanding salient dimensions of female adolescence is discussed. 相似文献
