Abstract
The objective of this study was to assess whether private high school students constitute a group that is at high risk for eating pathology. Female and male public and private high school students (N = 465) were compared on self-reported eating disordered attitudes and behaviors. Private high school students reported elevated eating disordered attitudes and behaviors when compared with students from public schools. The results were somewhat stronger for females than males. The findings suggest that private high school students are a group at high risk for eating pathology. The identification of such high risk groups may facilitate etiologic studies and aid in the implementation of targeted prevention programs.

Abstract
This article describes the development and validation of a brief self-report scale for diagnosing anorexia nervosa, bulimia nervosa, and binge-eating disorder. Study 1 used a panel of eating-disorder experts and provided evidence for the content validity of this scale. Study 2 used data from female participants with and without eating disorders (N = 367) and suggested that the diagnoses from this scale possessed temporal reliability (mean kappa = .80) and criterion validity (with interview diagnoses; mean kappa = .83). In support of convergent validity, individuals with eating disorders identified by this scale showed elevations on validated measures of eating disturbances. The overall symptom composite also showed test-retest reliability (r = .87), internal consistency (mean alpha = .89), and convergent validity with extant eating-pathology scales. Results implied that this scale was reliable and valid in this investigation and that it may be useful for clinical and research applications.

Abstract
This study examined data from a 4-year school-based longitudinal study (n = 1,124), to test whether the increase in major depression that occurs among girls during adolescence may be partially explained by the body-image and eating disturbances that emerge after puberty. Elevated body dissatisfaction, dietary restraint, and bulimic symptoms at study entry predicted onset of subsequent depression among initially nondepressed youth in bivariate analyses controlling for initial depressive symptoms. Although the unique effect for body dissatisfaction was not significant in the multivariate model, this set of risk factors was able to fairly accurately foretell which girls would go on to develop major depression. Results were consistent with the assertion that the body-image- and eating-related risk factors that emerge after puberty might contribute to the elevated rates of depression for adolescent girls.

Abstract
OBJECTIVE Although laboratory experiments suggest that negative affect inductions potentiate the relation between dieting and disinhibited eating, little research has tested whether this finding generalizes to binge eating in the natural environment. Thus, we assessed whether negative affect moderated the relation between dieting and binge eating in a passive-observational study. METHOD This aim was addressed with longitudinal data from a community sample of adolescents (N = 631). RESULTS For females, dieting and negative affect predicted binge eating in cross-sectional and prospective analyses, but negative affect potentiated the relation between dieting and binge eating only in the cross-sectional analyses. Similar, but attenuated results were found for males. DISCUSSION Findings converge with those from laboratory studies in suggesting that negative affect moderates the relation between dieting and binge eating, but also imply that dieting and negative affect constitute independent risk factors for binge eating. The lack of prospective effects may suggest that the interactive relations have a short time lag or are difficult to detect prospectively.

Abstract
OBJECTIVE Because psychoeducational primary prevention programs for eating disorders have met with little success, this preliminary experiment tested a dissonance-based targeted preventive intervention. METHOD Female undergraduates (N = 30) with elevated body image concerns were assigned to a three-session intervention, wherein they voluntarily argued against the thin ideal, or a delayed-intervention control condition. Participants completed a baseline, termination, and a 1-month follow-up survey. RESULTS The intervention resulted in a subsequent decrease in thin-ideal internalization, body dissatisfaction, dieting, negative affect, and bulimic symptomatology, with most changes remaining at the 1-month follow-up. DISCUSSION These preliminary results suggest that this dissonance-based targeted prevention intervention reduces bulimic pathology and known risk factors for eating disturbances, and provide experimental support for the claim that thin-ideal internalization contributes to body dissatisfaction, dieting, negative affect, and bulimic symptoms.

Abstract
This study examined the prospective relations of naturalistic weight-reduction efforts to growth in relative weight and onset of obesity with data from a community study of female adolescents (N = 692). Initial self-labeled dieting, appetite suppressant/laxative use, incidental exercise, vomiting for weight-control purposes, and binge eating predicted elevated growth in relative weight over the 4-year period. Dietary restraint, self-labeled dieting, exercise for weight-control purposes, and appetite suppressant/laxative use predicted an increased risk for obesity onset. Data imply that the weight-reduction efforts reported by adolescents are more likely to result in weight gain than in weight loss and suggest the need to educate youth on more effective weight-control strategies.

Abstract
OBJECTIVE This study investigated the course of eating attitudes and eating-disordered behaviors in a community sample of adult women. METHOD Participants (N = 166; mean age = 32.8 years) completed the Eating Disorder Inventory (EDI), the Three-Factor Eating Questionnaire (TFEQ), and a questionnaire assessing bulimic behaviors at two time points, 6 years apart. RESULTS Correlations for rank ordering of scores on these measures were all significant, indicating high rank stability over time. Although rates of specific bulimic behaviors decreased over time, mean scores on eating disorder attitude scales tended to increase. DISCUSSION Findings challenge the commonly held belief that disturbed eating attitudes decline with age.

Abstract
Etiologic models of bulimia center on dieting and negative affect, yet no research has subtyped bulimic individuals according to whether they fit dietary versus negative affect profiles. This study subtyped 265 bulimic women along dieting and depressive dimensions and tested whether subtypes showed differences in eating pathology, clinical correlates, and treatment response. Cluster analysis revealed a pure dietary subtype (62%) and a mixed dietary-depressive subtype (38%). Whereas dietary and dietary-depressive bulimic women showed similar levels of bulimic behaviors, the latter reported more eating and weight obsessions; social maladjustment; higher rates of mood, anxiety, eating, impulse control, and personality disorders; and poorer treatment response. Results suggest dieting is a central feature of bulimia, but depressive affect occurs in only a subset of cases. However, the combination of dieting and depressive affect seems to signal a more severe variant of bulimia.

Abstract
OBJECTIVE The present study had two primary objectives: (1) to examine differences in adolescent coping with temptations to use alcohol versus temptations for marijuana and/or other drug use and (2) to replicate and extend previous findings regarding the factor structure and psychometric validity of the Temptation Coping Questionnaire (TCQ). METHOD This was a cross-sectional study of 1,273 high school students, 52% female and, on average, 16.6 years old. The TCQ was completed as part of a school-wide survey of cigarette, alcohol and other drug involvement. Responses to the TCQ were elicited in response to two hypothetical temptation situations, one involving offers of alcohol only and the other involving offers of marijuana and/or other drugs. RESULTS The factor structure of the TCQ coping scale was confirmed for the original 11 items, both within and across situations representing temptations to use alcohol or marijuana and/or other drugs. In addition, the mean levels of perceived importance of abstaining and extent of coping efforts endorsed were higher for a marijuana and other drug than for an alcohol temptation situation. Finally, construct and criterion validity of the TCQ was replicated in the present sample. CONCLUSIONS Present results suggest that similar coping strategies are employed regardless of the particular substance encountered in a temptation situation. However, situation appraisal and extent of coping efforts appeared to differ for distinct substance types. These findings corroborate previous evidence for the utility of the TCQ as a brief, reliable measure of adolescent temptation coping and provide convergent support for the temptation-coping construct.

Abstract
Bulimia nervosa and binge-eating disorder are characterized by a persistent course, are associated with comorbid psychopathology, and can result in serious medical complications. Although current treatments for these disorders show promise, they are not effective for approximately 40% of clients. Significant advances have been made in psychosocial research on the etiology and maintenance of bulimia nervosa and binge-eating disorder, as well as on the predictors of treatment response. This article reviews these advances and discusses the clinical implications of these findings. Research on etiology and maintenance suggests that eating-disorder treatments might be improved by focusing greater attention on promoting healthy weight-control techniques, increasing resiliency to sociocultural pressures to be thin, reducing thin-ideal internalization, and fostering adaptive affect-regulation skills. Research on the predictors of response to treatment suggests that matching treatments to client characteristics might further bolster intervention effectiveness.

Abstract
OBJECTIVE Research suggests that eating problems are often present by preadolescence, yet little is known about the age of emergence of these early eating disturbances or risk factors for these behaviors. Thus, we investigated the timing of onset of disturbed eating during childhood and the predictors of these behaviors. METHOD These aims were addressed by following a sample of children and their parents (N = 216) for the first 5 years of the children's lives. RESULTS Data suggested that the risk for emergence of inhibited eating, secretive eating, overeating, and vomiting increased annually through age 5. Maternal body dissatisfaction, internalization of the thin-ideal, dieting, bulimic symptoms, and maternal and paternal body mass prospectively predicted the emergence of childhood eating disturbances. Infant feeding behavior and body mass during the first month of life also predicted the emergence of these behaviors. DISCUSSION Results suggest that eating disturbances emerge during childhood and may be a function of certain parental and child characteristics.

Abstract
This prospective study tested the assertion that psychopathology would predict both adolescent alcohol use and problem use, whereas socialization factors would predict only use, and explored mechanisms by which predictors led to problem use in a community sample of families (N = 216). Externalizing symptoms, parental alcoholism, peer influences, and parental support were indirectly related to negative consequences through their effects on use level. Externalizing symptoms, internalizing symptoms, peer influences, and parental approval of use directly predicted consequences, controlling for the indirect effects through use level. Internalizing pathology potentiated the relation between consumption and consequences, whereas parental support and control mitigated this relation. Collectively, findings provided mixed support for the assertion that psychopathology would predict both use and problem use, whereas socialization factors would predict only use.

Abstract
This prospective study examined age of onset for binge eating and purging among girls during late adolescence and tested whether dieting and negative affectivity predicted these outcomes. Of initially asymptomatic adolescents, 5% reported onset of objective binge eating, 4% reported onset of subjective binge eating, and 4% reported onset of purging. Peak risk for onset of binge eating occurred at age 16, whereas peak risk for onset of purging occurred at age 18. Adolescents more often reported onset of a single symptom rather than multiple symptoms, and symptoms were episodic. Dieting and negative affectivity predicted onset of binge eating and purging. Findings suggest that late adolescence is a high-risk period for onset of bulimic behaviors and identify modifiable risk factors for these outcomes.

Abstract
Although social influences are thought to promote bulimic pathology, little research has examined the effects of multiple socialization agents, or considered both modeling and social reinforcement processes. Accordingly, these two studies tested whether social reinforcement of the thin-ideal, and modeling of abnormal eating behavior by family, peers, and the media, (i) correlated with bulimic symptoms in a sample of young adult female (N = 114) and (ii) predicted the onset of bulimic behavior in a sample of adolescent females (N = 218). Social reinforcement of the thin-ideal by family, peers, and media was correlated with bulimic symptoms; family and peer social reinforcement prospectively predicted the onset of binge eating and purging. Family and peer, but not media, modeling of abnormal eating behavior was associated with concurrent bulimic symptoms, and predicted the onset of binge eating and purging. Results suggest that both social reinforcement and modeling processes may promote bulimic pathology, but imply that the effects are limited to family and peer influences.

Abstract
This study provides estimates of comorbid psychiatric disorders in women with binge eating disorder (BED). Sixty-one BED and 60 control participants, who were recruited from the community, completed the Structured Clinical Interview for DSM-III-R Axis I and Axis II disorders and self-report measures of eating and general psychiatric symptomatology. Regarding psychiatric diagnoses, women with BED had higher lifetime prevalence rates for major depression, any Axis I disorder, and any Axis II disorder relative to controls. BED women also evidenced greater eating and psychiatric symptomatology than did controls. Results suggest that the prevalence of comorbid psychiatric disorders in BED may be lower than previously indicated by clinical studies.

Abstract
There has been debate as to whether bulimia represents the endpoint of an eating disorder continuum (the continuity hypothesis) or is categorically different from subthreshold bulimia or an absence of eating disorders (the discontinuity hypothesis). The present study tested whether differences among bulimic, subthreshold bulimic, and control women on weight-concern and psychopathology variables better accord with the continuity or discontinuity hypothesis. These 3 groups were compared on body mass, thin-ideal internalization, body dissatisfaction, dietary restraint, depressive symptoms, anxiety symptoms, and temperamental emotionality. Discriminant function analysis and follow-up pairwise contrasts indicated that the continuity hypothesis was supported for measures of both weight concern and psychopathology. Research and treatment implications of the continuity perspective are discussed.

Abstract
OBJECTIVE Although theorists have proposed that restraint and negative affect cause bulimia nervosa, it is possible that bulimic pathology promotes restraint and negative affect, or that bulimic symptoms are reciprocally related to these two factors. The present study tested these competing models. METHOD Longitudinal data from a community sample of adolescent females (N = 218) was used to test these alternative models. RESULTS Prospective correlations suggested that bulimic pathology was reciprocally related to both restraint and negative affect. However, in more stringent tests controlling for the temporal stability of these factors, restraint was not related to subsequent bulimic symptoms, but bulimic pathology predicted future restraint. Negative affect and bulimic symptoms were not related over time when the stability of these factors was controlled, but they did show contemporaneous reciprocal relations. DISCUSSION Results provide some support for the negative affect model of bulimia, but raise questions about the restraint model.

Abstract
Studies indicate that various measures of dietary restraint show inconsistent relations to bulimic symptomatology. The present study tested the assertion that this is because the scales differ in the extent to which they reflect the success or failure of dietary efforts. This study also tested the competing hypothesis that criterion confounding of the Restraint Scale produced the inconsistent findings. Data from 117 undergraduates indicated that both the Restraint Scale and the Dutch Restrained Eating Scale were correlated with bulimic pathology, but that the magnitude to the relations were higher for the former. These results supported the dietary success failure hypothesis, however, this difference disappeared when the two disinhibited eating items from the Restraint Scale were deleted. Thus, the inconsistent findings in prior research appear to be due to the criterion confounding of the Restraint Scale. Implications for the measurement of restraint are discussed.

Abstract
Longitudinal latent growth models were used to examine the relation between changes in adolescent alcohol use and changes in peer alcohol use over a 3-year period in a community-based sample of 363 Hispanic and Caucasian adolescents. Both adolescent alcohol use and peer alcohol use were characterized by positive linear growth over time. Not only were changes in adolescent alcohol use closely related to changes in peer alcohol use, but the initial status on peer alcohol use was predictive of later increases in adolescent alcohol use and the initial status on adolescent alcohol use was predictive of later increases in peer alcohol use. These results are inconsistent with models positing solely unidirectional effects between adolescent alcohol use and peer alcohol use.
