The reliability and validity of a group-administered version of the body image assessment

The Body Image Assessment (BIA) is a simple measure of body image disturbance. However, it has currently only been used with an individual administration format and only to assess ratings of current body size, ideal body size, and body dissatisfaction. It has also only been validated for use with women. In the current two studies, the reliability and validity of a group-administered version of the BIA procedure for both men and women that also assessed ratings of the ideal opposite sex and predictions about what the opposite sex would prefer as most attractive was examined. In the first study, results indicated good test-retest reliability for the group version for current and ideal body size and good concurrent validity with the individual administration format of the BIA. The results of the second study supported the construct and predictive validity of the group administered BIA, suggesting that it is a time-efficient alternative to the original, individually administered assessment.     

Evaluation of the evidence for the trauma and fantasy models of dissociation

The relationship between a reported history of trauma and dissociative symptoms has been explained in 2 conflicting ways. Pathological dissociation has been conceptualized as a response to antecedent traumatic stress and/or severe psychological adversity. Others have proposed that dissociation makes individuals prone to fantasy, thereby engendering confabulated memories of trauma. We examine data related to a series of 8 contrasting predictions based on the trauma model and the fantasy model of dissociation. In keeping with the trauma model, the relationship between trauma and dissociation was consistent and moderate in strength, and remained significant when objective measures of trauma were used. Dissociation was temporally related to trauma and trauma treatment, and was predictive of trauma history when fantasy proneness was controlled. Dissociation was not reliably associated with suggestibility, nor was there evidence for the fantasy model prediction of greater inaccuracy of recovered memory. Instead, dissociation was positively related to a history of trauma memory recovery and negatively related to the more general measures of narrative cohesion. Research also supports the trauma theory of dissociation as a regulatory response to fear or other extreme emotion with measurable biological correlates. We conclude, on the basis of evidence related to these 8 predictions, that there is strong empirical support for the hypothesis that trauma causes dissociation, and that dissociation remains related to trauma history when fantasy proneness is controlled. We find little support for the hypothesis that the dissociation-trauma relationship is due to fantasy proneness or confabulated memories of trauma.     

Before the rules are written: navigating moral ambiguity in performance enhancement

In 1984, a number of US cyclists used blood transfusions to boost their performance at the Los Angeles Olympic Games. The cyclists broke no rules and dominated the Games, yet were later maligned as cheaters and dopers—they had, it seemed, violated some important norm, albeit one which was neither an official rule nor otherwise easily identifiable. Their case illustrates the moral ambiguity that arises when a performance enhancement is employed in a sport that has not addressed it. This article takes up the crucial question posed by such moral ambiguity: is it ethical to enhance performance through a substance or technology when no rules exist to prohibit it? We first examine ordinary ethical obligations that athletes carry based on their status as moral agents. We conclude that such obligations provide some guidance, but cannot resolve the issue. We then examine arguments that take sport as a unique social practice that presents its own moral obligation not to use performance enhancers. We argue that these ‘spirit of sport’ arguments, developed by McNamee and Loland and Hoppeler cannot resolve the issue either. We conclude that when the rules governing sport are silent on the issue of performance enhancement the constraints on its ethical use are limited at best.     

Cross-cultural investigation of the Questionnaire of Smoking Urges in American and Spanish smokers

This study evaluated the factor structure of the Questionnaire of Smoking Urges (QSU) across American and Spanish smokers. Using confirmatory factor analyses, the fits of one-, two-, and four-factor models of smoking craving in American and Spanish data sets were compared. The two-factor model provided the best fit in both samples. However, negatively worded items confounded the interpretation of the two-factor structure in both the American and Spanish data. The first factor had positively and negatively worded items, whereas the second had only positively worded items. The two-factor structure was reexamined, removing either the positively or the negatively worded items. Using only positively worded items resulted in a loss of fit, whereas using only negatively worded items improved model fit substantially. Thus, the results supported the generalization of smoking craving across Spanish and American smokers and suggested that negatively worded items play a larger role in the two-factor structure of the QSU than originally thought.     

The effects of child sexual abuse: Comment on Rind, Tromovitch, and Bauserman (1998).

B. Rind, P. Tromovitch, and R. Bauserman (1998) examined the long-term effects of childhood sexual abuse (CSA) by meta-analyzing studies of college students. The authors reported that effects "were neither pervasive nor typically intense" and that "men reacted much less negatively than women" (p. 22) and recommended value-neutral reconceptualization of the CSA construct. The current analysis revealed numerous problems in that study that minimized CSA-adjustment relations, including use of a healthy sample, an inclusive definition of CSA, failure to correct for statistical attenuation, and misreporting of original data. Rind et al.'s study's main conclusions were not supported by the original data. As such, attempts to use their study to argue that an individual has not been harmed by sexual abuse constitute a serious misapplication of its findings.     

Cross-ethnic equivalence of the Hopkins Symptom Checklist-21 in European American, African American, and Latino college students

To determine if the Hopkins Symptom Checklist-21 demonstrates equivalent validity across different ethnic groups, the authors tested the factor structure of the instrument with a sample of European American (n = 514), African American (n = 154), and Latino (n = 229) college students using confirmatory factor analysis with tests of invariance across groups. For the most part, a 3-factor model with Performance, General, and Somatic factors fit equally well for all 3 racial/ethnic groups. Differences involved only a few items in terms of either the strength of a factor loading or an error term. The results generally support the validity of the use of the instrument for measurement of distress in these different racial/ethnic groups.     

Validation of self-ideal body size discrepancy as a measure of body dissatisfaction

Recently, body dissatisfaction has been conceptualized as the discrepancy between self and ideal body size estimates. This study evaluated the validity of this conceptualization using three methods for estimating actual and ideal body size: (a) the Body Image Assessment, (b) the Body Image Testing System, and (c) the Body Image Detection Device. The three body image assessment procedures were concurrently administered to a sample of 110 women diagnosed: bulimia nervosa (n=18),obese (n=34),and non-eating disorder (n=58).The Eating Disorder Inventory Body Dissatisfaction scale was also used to measure body dissatisfaction. Measures of self-ideal body size discrepancy were found to correlate more highly with measures of body dissatisfaction than were measures of current body size perception, ideal body size, body size estimation accuracy, or indices based on actual body size. Estimation of both current and ideal body size were found to significantly predict overall body dissatisfaction; thus, both self and ideal body size measures were found to be significant components in determining body size dissatisfaction. These data were interpreted as supportive of the conceptualization of body dissatisfaction as the discrepancy between self and ideal body size estimates.     

Clarifying body-image disturbance: analysis of a multidimensional model using structural modeling

A multidimensional model of body-image disturbance was tested. The model incorporated the concepts of body-size distortion, preference for thinness, body dissatisfaction, and fear of fatness as predictors of restrictive eating. The LISREL 7 program was used to perform a structural modeling analysis of the theoretical model. A total of 175 women participated in the study (54 eating-disordered patients and 121 undergraduate students). The results supported the hypothesized four-dimensional model relative to alternative one-, two-, and three-dimensional models. Body dissatisfaction appeared to be directly affected by both body-size distortion and preference for thinness. Fear of fatness was found to be the best predictor of restrictive eating. The results appeared consistent across the clinical and nonclinical samples. These data may help resolve many of the current controversies in the body-image literature. The results also suggested the need to develop more sound assessment instruments for fear of fatness.
