Do Antifat Attitudes Predict Antifat Behaviors?

Kerry S. O'Brien, Janet D. Latner, Jamin Halberstadt, John A. Hunter, Jeremy Anderson, Peter Caputi
2008 Obesity  
objective: The aim of this study was to investigate discrimination against obese job candidates, and to examine whether widely used measures of implicit and explicit antifat attitudes are related to or predict antifat discrimination. Methods and Procedures: One hundred university students made job candidate suitability ratings of resumes submitted for a bogus managerial position. Photos attached to each resume portrayed the job candidate as either obese or normal weight, by using pre-and

Implicit and explicit antifat attitudes were also assessed. Results: Participants rated obese job candidates as having less leadership potential, as less likely to succeed, and as less likely to be employed than normal-weight candidates. Obese candidates were also given a lower starting salary and ranked as less qualified overall than candidates portrayed as normal weight. Neither implicit nor explicit antifat attitude measures were significantly related to antifat discrimination. Discussion: This study found strong evidence of employment-related discrimination against obese individuals. Commonly used measures of antifat attitudes do not appear to be adequate predictors of antifat discrimination. Improved questionnaire measures may be needed to better predict actual prejudiced behavior. s88 VOLUME 16 SUPPLEMENT 2 | NOVEMBER 2008 | articles Methods and Procedures Participants

Validation of Automated White Matter Hyperintensity Segmentation

Sean D. Smart, Michael J. Firbank, John T. O'Brien
2011 Journal of Aging Research  
Introduction. White matter hyperintensities (WMHs) are a common finding on MRI scans of older people and are associated with vascular disease. We compared 3 methods for automatically segmenting WMHs from MRI scans.Method. An operator manually segmented WMHs on MRI images from a 3T scanner. The scans were also segmented in a fully automated fashion by three different programmes. The voxel overlap between manual and automated segmentation was compared.Results. Between observer overlap ratio was

We investigated the use of a modified version of SPM segmentation; however, this was not successful, with only 14% overlap.Discussion. Using our previously reported software, we demonstrated good segmentation of WMHs in a fully automated fashion.
