It’s Not Just the What but the How

White House Task Force to Protect Students From Sexual Assault looked to Prevention Innovations Research Center to evaluate efficacy of strategies for prevention and response to sexual violence on campus

Campus Community Readiness to Engage Measure: Its Utility for Campus Violence Prevention Initiatives—Preliminary Psychometrics

The researchers present preliminary psychometric information on a recently developed measure—the Campus Community Readiness to Engage Measure (CCREM)—which was developed as a tool for campuses to determine their readiness to address sexual assault (SA) and relationship abuse (RA). Participants were 353 community leaders and administrators at 131 colleges and universities across New England. Factor analytic results demonstrated that the CCREM had three factors for both SA and RA: denial (the campus community is unwilling to acknowledge that SA and RA are issues for the community), initiation (the campus community is beginning to create efforts to address SA and RA and some community members are involved), and sustainability (the campus has high levels of engagement from community members and longstanding efforts to address SA and RA). Whereas there was fair to moderate agreement among raters within the same community on the sustainability and initiation subscales, there was poor to fair agreement among raters within the same community on the denial subscale. Although additional measurement development research is needed, preliminary data suggest that the CCREM may be useful to campus communities in helping to initiate prevention initiatives and implement services related to SA and RA

How Do We Know If It Works? Measuring Outcomes in Bystander-Focused Abuse Prevention on Campuses

Objective: To address acknowledged limitations in the effectiveness of sexual and relationship abuse prevention strategies, practitioners have developed new tools that use a bystander framework (Lonsway et al, 2009). Evaluation of bystander-focused prevention requires measures, specific to the bystander approach, that assess changes over time in participants’ attitudes and behaviors. Few measures exist and more psychometric analyses are needed. We present analyses to begin to establish the psychometric properties of four new measures of bystander outcomes and their subscales. Method: We collected data from 948 first year college students on two campuses in the northeast United States. Items assessing attitudes and behaviors related to bystander helping responses in college campus communities for situations where there is sexual or relationship abuse risk were factor analyzed. Results: Measures of readiness to help (assessed specifically with scales representing taking action, awareness, and taking responsibility), intent to be an active bystander, self-reported bystander responses, and perceptions of peer norms in support of action all showed adequate reliability and validity. Conclusion: The study represents a next step in the development of tools that can be used by researchers and practitioners seeking both to understand bystander behavior in the context of sexual and relationship abuse and evaluating the effectiveness of prevention tools to address these problems. The measures investigated will be helpful for prevention educators and researchers evaluating the effectiveness of sexual and relationship abuse education tools that use a bystander intervention framework

The effect of macro and micro-nutrient fortification of biscuits on their sensory properties and on hedonic liking of older people

BACKGROUND: Under-nutrition in older adults is widespread. Oral nutritional supplement beverages (ONS) are prescribed, yet consumption by older people is often insufficient. A variety of supplement formats may improve nutrient intake. This study developed protein and micro-nutrient fortified biscuits and evaluated their sensory attributes and liking by older people. Two micro-nutrient strategies were taken, to match typical ONS and to customise to the needs of older people. RESULTS: Oat biscuits and gluten-free biscuits developed contained over 12% protein and over 460 kcal 100 g-1 . Two small (40 g) biscuits developed to match ONS provided approximately 40% of an ONS portion of micro-nutrients and 60% of macro-nutrients; however, the portion size was considered realistic whereas the average ONS portion (200 mL) is excessive. Biscuits developed to the needs of older adults provided, on average, 18% of the reference nutrient intake of targeted micro-nutrients. Sensory characteristics were similar between biscuits with and without micro-nutrient fortification, leading to no differences in liking. Fortified oat biscuits were less liked than commercial oat biscuits, partly attributed to flavour imparted by whey protein fortification. CONCLUSION: Macro- and micro-nutrient fortification of biscuits could provide an alternative fortified snack to help alleviate malnutrition in older adults

Changing Attitudes About Being a Bystander to Violence: Translating an In-Person Sexual Violence Prevention Program to a New Campus

Bystander approaches to reducing sexual violence train community members in prosocial roles to interrupt situations with risk of sexual violence and be supportive community allies after an assault. This study employs a true experimental design to evaluate the effectiveness of Bringing in the Bystander™ through 1-year post-implementation with first-year students from two universities (one rural, primarily residential; one urban, heavily commuter). We found significant change in bystander attitudes for male and female student program participants compared with the control group on both campuses, although the pattern of change depended on the combination of gender and campus

Development of the shift smartphone app to support the emotional well-being of junior physicians : Design of a prototype and results of usability and acceptability testing

Background: Junior physicians report higher levels of psychological distress than senior doctors and report several barriers to seeking professional mental health support, including concerns about confidentiality and career progression. Mobile health (mHealth) apps may be utilized to help overcome these barriers to assist the emotional well-being of this population and encourage help-seeking. Objective: This study describes the development and pilot trial of the Shift mHealth app to provide an unobtrusive avenue for junior physicians to seek information about, and help for, well-being and mental health concerns, which is sensitive to workplace settings. Methods: A 4-phase iterative development process was undertaken to create the content and features of Shift involving junior physicians using the principles of user-centered design. These 4 phases were—needs assessment, on the basis of interviews with 12 junior physicians; prototype development with user experience feedback from 2 junior physicians; evaluation, consisting of a pilot trial with 22 junior physicians to assess the usability and acceptability of the initial prototype; and redesign, including user experience workshops with 51 junior physicians. Results: Qualitative results informed the content and design of Shift to ensure that the app was tailored to junior physicians’ needs. The Shift app prototype contained cognitive behavioral, mindfulness, value-based actions, and psychoeducational modules, as well as a tracking function that visualized patterns of daily variations in mood and health behaviors. Pilot-testing revealed possible issues with the organization of the app content, which were addressed through a thorough restructuring and redesign of Shift with the help of junior physicians across 3 user experience workshops. Conclusions: This study demonstrates the importance of ongoing end user involvement in the creation of a specialized mHealth app for a unique working population experiencing profession-specific stressors and barriers to help-seeking. The development and pilot trial of this novel Shift mHealth app are the first steps in addressing the mental health and support-seeking needs of junior physicians, although further research is required to validate its effectiveness and appropriateness on a larger scale

Bereavement and marriage are associated with antibody response to influenza vaccination in the elderly

Stressful life events exposure including bereavement, an event commonly experienced by elderly people, social support, marital status and satisfaction were examined in relation to antibody response to the annual trivalent influenza vaccination in an elderly community sample (N = 184). Antibody response was assessed at baseline, and at one and 12 months following vaccination. Taking into account baseline antibody titer, overall life events exposure and social support were not associated with response to any of the influenza strains. However, bereavement in the year prior to vaccination was negatively associated with the one-month response to the A/Panama and B/Shangdong strains. Being married and having higher marital satisfaction was also associated with higher peak responses to the A/Panama influenza strain at one month. The positive association between marital satisfaction and A/Panama response was particularly evident in the younger half of the married sample. These associations largely withstood adjustment for potential confounders. Thus, in the elderly, peak antibody response was associated with bereavement and marriage, and not the more general factors, life events and social support, related to antibody response in student samples. This suggests the importance of taking a life course approach to examining relationships between psychosocial factors and immunity, and that interventions to modify the impact of these factors should address those most salient for each age group

Identification of d -arabinan-degrading enzymes in mycobacteria

Bacterial cell growth and division require the coordinated action of enzymes that synthesize and degrade cell wall polymers. Here, we identify enzymes that cleave the D-arabinan core of arabinogalactan, an unusual component of the cell wall of Mycobacterium tuberculosis and other mycobacteria. We screened 14 human gut-derived Bacteroidetes for arabinogalactan-degrading activities and identified four families of glycoside hydrolases with activity against the D-arabinan or D-galactan components of arabinogalactan. Using one of these isolates with exo-D-galactofuranosidase activity, we generated enriched D-arabinan and used it to identify a strain of Dysgonomonas gadei as a D-arabinan degrader. This enabled the discovery of endo- and exo-acting enzymes that cleave D-arabinan, including members of the DUF2961 family (GH172) and a family of glycoside hydrolases (DUF4185/GH183) that display endo-D-arabinofuranase activity and are conserved in mycobacteria and other microbes. Mycobacterial genomes encode two conserved endo-D-arabinanases with different preferences for the D-arabinan-containing cell wall components arabinogalactan and lipoarabinomannan, suggesting they are important for cell wall modification and/or degradation. The discovery of these enzymes will support future studies into the structure and function of the mycobacterial cell wall
