Body image change in obese and overweight women enrolled in a weight-loss intervention: the importance of perceived versus actual physical changes

Using the exercise and self-esteem model as a guiding framework, this study examined variables related to body image change among 88 overweight and obese women (M(age)=28.4±7.8; M(BMI)=31.6±3.5) participating in a 16-week diet and exercise weight-loss intervention. Measures of body image and potential mechanisms of body image change (actual and perceived physical changes, self-efficacy) were administered at baseline, Weeks 8 and 16. Body image improved significantly over the study time-points (ps<.001). Perceived physical changes accounted for most explained variance (12-37%) in body image change (total R(2)(adj)=.21-.50). Improved perceptions of body fat were a particularly important predictor in each model (ps≤.04). Results support the notion that to improve body image, perceived changes to the body are more important than actual changes. Such information is integral to developing theories to explain body image change and interventions to maximize it.     

Engaging with research ethics in central Francophone Africa: reflections on a workshop about ancillary care

ABSTRACT: Research ethics is predominantly taught and practiced in Anglophone countries, particularly those in North America and Western Europe. Initiatives to build research ethics capacity in developing countries must attempt to avoid imposing foreign frameworks and engage with ethical issues in research that are locally relevant. This article describes the process and outcomes of a capacity-building workshop that took place in Kinshasa, Democratic Republic of Congo in the summer of 2011. Although the workshop focused on a specific ethical theme - the responsibilities of researchers to provide health-related care to their research participants - we argue that the structure of the workshop offers a useful method for engaging with research ethics in general, and the theme of ancillary care encourages a broad perspective on research ethics that is highly pertinent in low-income countries. The workshop follows an interactive, locally driven model that could be fruitfully replicated in similar settings.     

Training Experiences as Mediators of the Association Between Gender-Role Egalitarianism and Women��s Adjustment to Marine Recruit Training

Women may face particular challenges adjusting to the military environment, in part due to their numerical minority status in a traditionally male culture. In addition, women are more likely than men to experience the added stressor of sexual harassment. We examined several potential mediators of the relationship between gender-role egalitarianism and adjustment to boot camp training in a sample of 658 female U.S. Marine recruits. Results indicated that sexual harassment, performance stress, and unit cohesion mediated the relationship between egalitarianism and mental health symptomatology. These findings suggest that beliefs about gender roles are important to consider in efforts to improve women??s adjustment in the military.     

HR Interventions that Go Viral

What causes one Human Resource (HR) intervention to thrive while another dies? The purpose of this paper is to explore the characteristics of HR interventions that are not only self-sustaining, but adapt and gain momentum over time. Based on a review of the literature, a case study, and 16 critical incident interviews with senior Industrial-Organizational (I–O) and HR professionals, several characteristics of the organization, the intervention, and the leader consistently emerged as important in creating sustainable HR programs, suggesting several new directions for future research.     

Adapting Mindfulness-Based Cognitive Therapy for Treatment-Resistant Depression: A Clinical Case Study

Major depressive disorder (MDD) is currently ranked the third leading cause of disability in the world. Treatment-Resistant Depression (TRD) causes the majority of MDD's disability. Strikingly, 50% of individuals with MDD will fail to remit with two adequate trials of antidepressant medications, thus qualifying as treatment resistant. Current pharmacological and psychotherapeutic treatment strategies for TRD are limited in effectiveness so new interventions are needed. Mindfulness-Based Cognitive Therapy (MBCT) is a new psychotherapeutic treatment with established efficacy in preventing relapse of depression for individuals in complete remission. MBCT is a group-based, 8-week intervention that uses mindfulness meditation as its core therapeutic technique. It teaches people to have a different relationship to depressive thoughts and feelings. Strategies are focused on decreasing rumination, enhancing self-compassion, increasing acceptance and decreasing avoidance. This modified version of MCBT, which includes the use of metaphor and adaptations of the original intervention will be discussed through the clinical case of a woman with long-standing TRD. A brief review of the current MBCT literature and future directions for the treatment of TRD are discussed.     

An Examination of the Association between Difficulties with Emotion Regulation and Dating Violence Perpetration

The perpetration of aggression in dating relationships is a prevalent problem among college students. Research that examines factors related to perpetrating dating violence is needed, as this could help guide prevention programming. This study examined how emotion regulation is related to dating violence perpetration among male and female college students (N = 440). Findings showed that the association between broad difficulties with emotion regulation, as well as more specific emotion regulation problems, were associated with dating violence perpetration and could differentiate individuals who had perpetrated and not perpetrated aggression. These findings varied slightly depending on the gender of the perpetrator and the type of aggression examined. Implications of these findings for prevention programs and future research are discussed.     

Voice pitch influences perceptions of sexual infidelity

Sexual infidelity can be costly to members of both the extra-pair and the paired couple. Thus, detecting infidelity risk is potentially adaptive if it aids in avoiding cuckoldry or loss of parental and relationship investment. Among men, testosterone is inversely related to voice pitch, relationship and offspring investment, and is positively related to the pursuit of short-term relationships, including extra-pair sex. Among women, estrogen is positively related to voice pitch, attractiveness, and the likelihood of extra-pair involvement. Although prior work has demonstrated a positive relationship between men?s testosterone levels and infidelity, this study is the first to investigate attributions of infidelity as a function of sexual dimorphism in male and female voices. We found that men attributed high infidelity risk to feminized women?s voices, but not significantly more often than did women. Women attributed high infidelity risk to masculinized men?s voices at significantly higher rates than did men. These data suggest that voice pitch is used as an indicator of sexual strategy in addition to underlying mate value. The aforementioned attributions may be adaptive if they prevent cuckoldry and/or loss of parental and relationship investment via avoidance of partners who may be more likely to be unfaithful.     

Eyes pursue moving objects, not retinal motion signals

For smooth-pursuit eye movements, a moving target is necessary, but we show that it is not sufficient. Observers pursued targets that appeared to move in one direction even though they really moved in another. Changes in perceived direction did not disrupt pursuit eye movements, but motion-based failures in object parsing did.     

Vestibular stimulation affects optic-flow sensitivity

Typically, multiple cues can be used to generate a particular percept. Our area of interest is the extent to which humans are able to synergistically combine cues that are generated when moving through an environment. For example, movement through the environment leads to both visual (optic-flow) and vestibular stimulation, and studies have shown that non-human primates are able to combine these cues to generate a more accurate perception of heading than can be obtained with either cue in isolation. Here we investigate whether humans show a similar ability to synergistically combine optic-flow and vestibular cues. This was achieved by determining the sensitivity to optic-flow stimuli while physically moving the observer, and hence producing a vestibular signal, that was either consistent with the optic-flow signal, eg a radially expanding pattern coupled with forward motion, or inconsistent with it, eg a radially expanding pattern with backward motion. Results indicate that humans are more sensitive to motion-in-depth optic-flow stimuli when they are combined with complementary vestibular signals than when they are combined with conflicting vestibular signals. These results indicate that in humans, like in nonhuman primates, there is perceptual integration of visual and vestibular signals.
