A qualitative study of perceived social barriers to care for eating disorders: Perspectives from ethnically diverse health care consumers

Objective: The study aim was to identify and describe health consumer perspectives on social barriers to care for eating disorders in an ethnically diverse sample. Method: We conducted an exploratory secondary analysis of qualitative data comprising transcripts from semi-structured interviews with past and prospective consumers of eating disorder treatment (n = 32). Transcripts were inputted into NVivo 8 for coding, sorting, and quantifying thematic content of interest within strata defined by ethnic minority and non-minority participants. We then examined the influence of key social barriers—including stigma and social stereotypes—on perceived impact on care. Results: The majority of respondents (78%) endorsed at least one social barrier to care for an eating or weight concern. Perceived stigma (or shame) and social stereotyping—identified both within social networks and among clinicians—had adversely impacted care for 59% and 19% of respondents, respectively. Discussion: Social barriers to care for eating and weight related concerns may be prevalent in the U.S. and impact both ethnic minority and non-minority health care consumers. © 2009 by Wiley Periodicals, Inc

Toward an understanding of risk factors for binge-eating disorder in black and white women: A community-based case-control study

This study sought to identify in white women risk factors specific to binge-eating disorder (BED) and for psychiatric disorders in general, and to compare black and white women on risk factors for BED.

Validity and Reliability of a Fijian Translation and Adaptation of the Eating Disorder Examination Questionnaire

Objective: Assessment of disordered eating has uncertain validity across culturally diverse populations. This study evaluated Eating Disorder Examination Questionnaire (EDE-Q) performance in an ethnic Fijian study population. Method: The EDE-Q was translated, adapted, and administered to school-going Fijian adolescent females (N = 523). A subsample (n = 81) completed it again within ∼1 week. We assessed feasibility, internal consistency, and test-retest reliability; evaluated construct validity through factor analysis and correlation with similar constructs; and examined the marginal utility of an additional question on traditional purgative use. Results: Internal consistency reliability was adequate for the global scale and subscales (Cronbach's alpha = 0.66–0.91); retest reliability was adequate for both the languages (range of ICCs, 0.50–0.79, and of kappas, 0.46–0.81, excluding purging items). Construct validity was supported by significant correlations with measures of similar constructs. Factor analysis confirms multiple dimensions of eating disorder symptoms but suggests possible culture-specific variation in this population. The majority of respondents endorsing traditional purgative use (58%) did not endorse conventional EDE-Q items assessing purging.Discussion: The EDE-Q is a valid measure of eating disorder pathology for ethnic Fijian adolescent females and measures a unitary underlying construct. © 2009 by Wiley Periodicals, Inc.

Transform-domain analysis of packet delay in network nodes with QoS-aware scheduling

In order to differentiate the perceived QoS between traffic classes in heterogeneous packet networks, equipment discriminates incoming packets based on their class, particularly in the way queued packets are scheduled for further transmission. We review a common stochastic modelling framework in which scheduling mechanisms can be evaluated, especially with regard to the resulting per-class delay distribution. For this, a discrete-time single-server queue is considered with two classes of packet arrivals, either delay-sensitive (1) or delay-tolerant (2). The steady-state analysis relies on the use of well-chosen supplementary variables and is mainly done in the transform domain. Secondly, we propose and analyse a new type of scheduling mechanism that allows precise control over the amount of delay differentiation between the classes. The idea is to introduce N reserved places in the queue, intended for future arrivals of class 1

The Figure Rating Scale as an Index of Weight Status of Women on Videotape

Objective: To determine whether Stunkard's Figure Rating Scale (FRS) is a valid and reliable index of weight status when an unbiased observer assigns the figure ratings of adult women viewed on videotape. Research Methods and Procedures: Seventy‐two women drawn from a community sample participated in a videotaped study in which height and weight were measured. The FRS is a rating scale displaying 9 silhouettes ranging from very thin to very obese. Women were assigned a figure rating “in‐person” by a research assistant (FRS used as a 17‐point scale) and by additional research assistants viewing women only on videotape (FRS used as both a 17‐ and 9‐point scale). Pearson's correlation coefficients were calculated for in‐person figure ratings, mean videotape figure ratings, and BMI. Results: BMI and in‐person figure ratings were highly correlated ( r = 0.91), as were BMI and both mean 17‐point videotape figure ratings and mean 9‐point videotape figure ratings ( r = 0.89 and 0.87, respectively). Inter‐rater agreement for in‐person figure ratings and mean 17‐point videotape figure ratings was 0.86, and agreement between in‐person figure ratings and mean 9‐point videotape figure ratings was 0.82. Discussion: The FRS can be used as an index of women's weight status by an unbiased observer, with subjects viewed in‐person or on videotape.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/93750/1/oby.2006.249.pd
