Deficits in emotion regulation mediate the relationship between childhood abuse and later eating disorder symptoms

The present study examined the relationship of child maltreatment to both emotion dysregulation and subsequent eating pathology. In an effort to extend previous research, the authors examined the unique impact of childhood emotional abuse (CEA) on emotion dysregulation and eating disorder (ED) symptoms while controlling for the effects of sexual and physical abuse. Structural equation modeling was utilized to simultaneously examine the effects of all three abuse types on multiple dependent variables as well as examine whether deficits in emotion regulation mediated the relationship between abuse and eating pathology. Results from a survey of 1,254 female college students revealed significant paths from abuse subtypes to specific eating disorder symptoms, with CEA evidencing the strongest association with ED symptoms. Additionally, emotion dysregulation was positively associated with ED symptoms, and mediated the effects of emotional abuse on symptoms. Findings support previous research on the enduring effects of emotional abuse as well as highlight the importance of the assessment of CEA in the treatment of ED symptoms.

Evaluation of a university course to promote physical activity: project GRAD

Project GRAD (Graduate Ready for Activity Daily) evaluates a university course to promote physical activity. In a randomized study, 338 university seniors participated in either an intervention or control course for academic credit, and posttest data were collected on 321. The control course was knowledge-oriented. The intervention course taught behavior change skills in weekly lectures and peer-led labs. Physical activity was assessed with 7-Day Physical Activity Recall interviews. The intervention had no significant effects on men. Among women, the intervention increased total physical activity during leisure, strengthening exercises, and flexibility exercise. This university course had the intended effects of promoting healthful patterns of physical activity among women, but no effects were observed on men, who were more active than women at baseline.     

Characteristics of project management at institutions sponsoring National Library of Medicine MedlinePlus Go Local

Objectives:

Through interviews with the National Library of Medicine''s MedlinePlus Go Local collaborators, an evaluation team sought to identify process characteristics that are critical for long-term sustainability of Go Local projects and to describe the impact that Go Local projects have on sponsoring institutions.

Methods:

Go Local project coordinators (n = 44) at 31 sponsor institutions participated in semi-structured interviews about their experiences developing and maintaining Go Local sites. Interviews were summarized, checked for accuracy by the participating librarians, and analyzed using a general inductive methodology.

Results:

Institutional factors that support Go Local projects were identified through the interviews, as well as strategies for staffing and partnerships with external organizations. Positive outcomes for sponsoring institutions also were identified.

Conclusions:

The findings may influence the National Library of Medicine team''s decisions about improvements to its Go Local system and the support it provides to sponsoring institutions. The findings may benefit current sponsoring institutions as well as those considering or planning a Go Local project.

Highlights

• Many project coordinators said they underestimated the level of work their National Library of Medicine (NLM) MedlinePlus Go Local projects would require, but most expressed dedication to the project and optimism about project sustainability.
• An institutional record of community service or outreach and a director who was supportive of the project were important factors in the progress and sustainability of Go Local projects.
• Go Local projects brought recognition to some sponsoring institutions from their parent institutions or their communities and provided opportunities to establish better relations with other libraries and institutions.
• Go Local projects ran more smoothly when a person, even a temporary hire, with dedicated time for the project was in charge during the initial building phase. Volunteer assistance has been difficult to motivate and sustain.

Implications

• NLM''s Go Local proposal guidelines accurately identify the factors that institutions should pay close attention to when planning a Go Local project.
• NLM should emphasize continuity plans to address project coordinator turnover.
• NLM should develop a more formal orientation plan for new project coordinators to assist program continuity at the sponsoring institutions.

     

Beyond the online catalog: developing an academic information system in the sciences

The online public access catalog consists essentially of a machine-readable database with network capabilities. Like other computer-based information systems, it may be continuously enhanced by the addition of new capabilities and databases. It may also become a gateway to other information networks. This paper reports the evolution of the Bibliographic Access and Control System (BACS) of Washington University in end-user searching, current awareness services, information management, and administrative functions. Ongoing research and development and the future of the online catalog are also discussed.
