‘I think a little bit of a kick is sometimes what you need’: Women’s accounts of whole-body scanning and likely impact on health-related behaviours

Objective: This study was designed to investigate whether whole-body scanning might promote healthy eating and physical activity in women, and to explore the effects of scanning on body image.

Design: Fourteen women aged 22–45 years without histories of eating disorders or whole-body scanning took part in semi-structured interviews before and after scanning. Data were analysed using inductive thematic analysis.

Results: Scans did not look as expected, and participants expressed ‘surprise’ and ‘shock’. Participants focused on perceived negative aspects of their bodies as revealed in scan images, and agreed that women with body concerns would find scans too ‘real’ and ‘raw’. Eleven women who met UK Government physical activity and healthy eating guidelines reported that the scan provided additional motivation to maintain, and in nine cases to increase, those behaviours. Two women who neither exercised nor ate healthily would not increase physical activity or change their diets significantly following scanning.

Conclusion: Whole-body scanning may enable maintenance or even acceleration of physical activity and healthy eating, but is unlikely to be useful in promoting initiation of these behaviours. Participants engaged in unhelpful body critique when viewing scans; scanning needs to be confined to contexts where support is provided, to avoid increasing body-related concerns.     

Racial/ethnic bullying: Exploring links between bullying and racism in the US workplace

This study examined relations between the incidence of workplace bullying and the everyday experiences of members of ethnic and racial minorities in the American workplace. Particular attention was paid to expressions of bullying that overtly or specifically refer to race or ethnicity, in the form of more or less subtle acts of discrimination and hostile treatment, introducing the term `racial/ethnic bullying.' Participants belonging to four racial/ethnic groups (Asians, African-Americans, Hispanics/Latinos, and whites) responded to a written survey of general and racial/ethnic bullying experiences, responses, and preferred modes and methods of internal organizational redress and dispute resolution. Very different profiles emerged between bullying perpetrated by supervisors/superiors versus co-workers/peers in the organization.     

Gender Symmetry and Asymmetry in Violent Relationships: Patterns of Mutuality Among Racially Diverse Women

Three patterns of mutual intimate partner violence (IPV) are proposed, based on frequency and severity: Male primary perpetrator (MPP), female primary perpetrator (FPP), and symmetrical (SYM). Patterns and effects of ethnicity were examined with 445 African American, Euro-American, and Mexican American low-income women experiencing mutual IPV. More relationships were classified as MPP (54%) than SYM (35%) or FPP (11%). Comparing women's and men's perpetration of several types of IPV (e.g., threats, severe physical) indicated MPP-pattern women experienced all IPV types more often and were more likely to sustain injury than their male partners. Fewer gender differences were found in the FPP pattern. Racial/ethnic groups were more similar than different; previously reported differences may be explained by variation in socioeconomic status. The larger part of the study was funded by grant R49/CCR610508 from the National Center for Injury Prevention and Control of the Centers for Disease Control and Prevention, awarded to the third author. This article was also made possible by grant 2001-WT-BX-0504 from the National Institute of Justice awarded to the first and third authors. These agencies are not responsible for the results. Portions of this paper were presented by the first and third authors at the International Family Violence Conference in Portsmouth, NH, July, 2003.     

青少年身体自我的发展特点和性别差异研究

对1699名青少年学生用自编具有较好信度和效度指标的身体自我量表进行测试。结果表明：青少年学生对身体的满意度从“最满意”到“最不满意”依次是负面特征、相貌特征、性特征、运动特征和身材特征,随年龄的增长其发展呈现波动性,青春期早期和中期呈明显下降趋势,青春期后期有缓慢上升;身体自我在相貌特护、身材特征、性特征、负面特征方面都存在显著的性别差异,男生比女生对身体更满意;城市学生比农村学生对自己的身体更满意。     

学习困难的ERP研究

事件相关脑电位（Event—related potentials,ERPs）是研究心理学和认知神经科学的重要技术手段,将该技术用于学习困难的脑机制的研究,有助于发现学习困难的神经机制。研究表明,学习困难者的P300波幅较小,潜伏期较长。学习困难者的MMN波幅比控制组小,在信息的自动加工方面存在缺陷。在单词命名任务中,学习困难者的N400较小,而且不同类型学习困难者的波幅和潜伏期存在明显差异。     

Victims of Abuse by Priests: Some Preliminary Observations

This paper describes the results of psychological assessments of 25 adult males who were victims of sexual abuse by Catholic priests as children or early adolescents. Preliminary data suggest that premorbid personality patterns in these victims put them at greater risk for abuse and also exacerbated the effects of their victimization. These observations are considered in the context of prevalent explanatory models of the traumagenic effects of child sexual abuse.     

Incarcerated Mothers: Mutual Support Groups Aimed at Reducing Substance Abuse Relapse and Recidivism

Interventions to reduce relapse and recidivism for the increasing number of mothers incarcerated for illicit drug use are needed to prevent maternal/child separation and high public expenditures. This paper describes mutual support groups for women inmates aimed at strengthening family coping skills, especially communication, anger management, and parenting skills. Qualitative data collected during the group sessions indicated that the healing support of shared experiences, stories, poetry, and staying in the present were identified as spiritually uplifting. Problem solving and improved family interactions constituted additional themes extracted from the qualitative data. Future plans include including quantitative outcome measures of success.     

The mediating and moderating effects of differentiation of self on body mass index and depressive symptomatology among an American college sample

Differentiation of self – a core construct of Bowen's (Bowen, M. (1978). Family therapy in clinical practice. New York: Jason Aronson) family systems theory – was examined as a possible predictor of psychological health and physical health and as a mediator and moderator of the relation between overall functioning and psychological health and physical health. A total of 818 American college students participated (mean age?=?23.72, SD?=?4.79) in this study. Differentiation of self was correlated and was predictive of psychological health, as measured by the Beck depression inventory, and physical health, as measured by body mass index (BMI). A multivariate multiple regression model revealed that differentiation of self partially mediated the effects of overall functioning on depressive symptomatology and on BMI. Results from a hierarchical regression model showed that differentiation of self moderated the relation between overall functioning and depressive symptomatology but did not moderate the relation between overall functioning and BMI. Taken together, these preliminary findings provide initial evidence of the importance of the associations between family systemic factors (differentiation of self) and psychological and physical health factors among American college populations.

Exploring the theoretical underpinnings of driving whilst influenced by illicit substances

An increasing number of studies are highlighting the alarming proportion of motorists that drive after having consumed illicit drugs. However presently, little attention has focused on the factors that may facilitate drug driving from a criminogenic paradigm. This study evaluated the contribution of deterrence, defiance, and deviance theories on intentions to drug drive to determine factors that might facilitate or reduce this behaviour. A total of 922 individuals completed a questionnaire that assessed frequency of drug use and a variety of perceptions on deterrence, defiance, and deviance constructs. The analysis showed that the defiance constructs (i.e., experiencing feelings of shame and believing in the legitimacy of sanctioning authority) and the deviance constructs (i.e., moral attachment to the norm and having a criminal conviction) were predictive of drug driving intentions. The facets of deterrence theory were not found to be significant predictors. Ultimately, this study illustrates that a range of behavioural and perceptual factors have the capacity to influence decisions to drug drive. As a result, there appears the need to extend the focus of research endeavours beyond legal sanctions to examine other factors that may be utilised to both understand the aetiology of drug driving as well as increase the possibility of compliance with the corresponding legislation.
