The relationship between eating disorder not otherwise specified (EDNOS) and officially recognized eating disorders: Meta-analysis and implications for DSM.

Eating disorder not otherwise specified (EDNOS) is the most prevalent eating disorder (ED) diagnosis. In this meta-analysis, the authors aimed to inform Diagnostic and Statistical Manual of Mental Disorders revisions by comparing the psychopathology of EDNOS with that of the officially recognized EDs: anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). A comprehensive literature search identified 125 eligible studies (published and unpublished) appearing in the literature from 1987 to 2007. Random effects analyses indicated that whereas EDNOS did not differ significantly from AN and BED on eating pathology or general psychopathology, BN exhibited greater eating and general psychopathology than EDNOS. Moderator analyses indicated that EDNOS groups who met all diagnostic criteria for AN except for amenorrhea did not differ significantly from full syndrome cases. Similarly, EDNOS groups who met all criteria for BN or BED except for binge frequency did not differ significantly from full syndrome cases. Results suggest that EDNOS represents a set of disorders associated with substantial psychological and physiological morbidity. Although certain EDNOS subtypes could be incorporated into existing Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) categories, others—such as purging disorder and non-fat-phobic AN—may be best conceptualized as distinct syndromes.

Managing Coordination Complexity in the Remanufacturing of Aircraft Engines

The complexity of communication and coordination stemming from teams responsible for adjusting interdependent parameters of components is a fundamental feature in the aircraft engine remanufacturing engineering project. To manage coordination complexity, the features of the remanufacturing process of aircraft engine are analyzed and a systematic method is presented to measure and optimize the dependency between coupled components. Furthermore, quantitative models are built based on Design Structure Matrix (DSM) models to measure dependency strengths related to the parameter features of the components. Also, a two-stage DSM clustering criteria is used to reduce the complexity of an organization. An industrial example is provided to illustrate the proposed models. The results showed that the proposed approach can reduce total coordination complexity.     

Challenges associated with a polythetic diagnostic system: Criteria combinations in the personality disorders.

Converging research on the diagnostic criteria for personality disorders (PDs) reveals that most criteria have different psychometric properties. This finding is inconsistent with the PD diagnostic system according to the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994), which weights each criterion equally. The purpose of the current study was to examine the potential effects of using equal weights for differentially functioning criteria. Data from over 2,100 outpatients were used to analyze and score response patterns to the diagnostic criteria for 9 PDs within an item response theory framework. Results indicated that combinations that included the same number of endorsed criteria yielded differing estimates of PD traits, depending on which criteria were met. Moreover, trait estimates from subthreshold criteria combinations often overlapped with diagnostic (at-threshold or higher) combinations, indicating that there were subthreshold combinations of criteria that indicated as much or more PD than did some combinations at the diagnostic threshold. These results suggest that counting the number of criteria an individual meets provides only a coarse estimation of his or her PD trait level. Implications for the assessment of polythetically defined mental disorders and for the PD proposal for the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders are discussed.

Borderline personality traits and disorder: Predicting prospective patient functioning.

Objective: Decisions about the composition of personality assessment in the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM–V) will be heavily influenced by the clinical utility of candidate constructs. In this study, we addressed 1 aspect of clinical utility by testing the incremental validity of 5-factor model (FFM) personality traits and borderline personality disorder (BPD) symptoms for predicting prospective patient functioning. Method: FFM personality traits and BPD features were correlated with one another and predicted 2-, 4-, 6-, 8-, and 10-year psychosocial functioning scores for 362 patients with personality disorders. Results: Traits and symptom domains related significantly and pervasively to one another and to prospective functioning. FFM extraversion and agreeableness tended to be most incrementally predictive of psychosocial functioning across all intervals; cognitive and impulse action features of BPD features incremented FFM traits in some models. Conclusions: These data suggest that BPD symptoms and personality traits are important long-term indicators of clinical functioning that both overlap with and increment one another in clinical predictions. Results support the integration of personality traits and disorders in DSM–V. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
