Abstract
This analysis is a follow-up to an earlier investigation of 182 genes selected as likely candidate genetic variations conferring susceptibility to anorexia nervosa (AN). As those initial case-control results revealed no statistically significant differences in single nucleotide polymorphisms, herein, we investigate alternative phenotypes associated with AN. In 1762 females, using regression analyses, we examined the following: (i) lowest illness-related attained body mass index; (ii) age at menarche; (iii) drive for thinness; (iv) body dissatisfaction; (v) trait anxiety; (vi) concern over mistakes; and (vii) the anticipatory worry and pessimism versus uninhibited optimism subscale of the harm avoidance scale. After controlling for multiple comparisons, no statistically significant results emerged. Although results must be viewed in the context of limitations of statistical power, the approach illustrates a means of potentially identifying genetic variants conferring susceptibility to AN because less complex phenotypes associated with AN are more proximal to the genotype and may be influenced by fewer genes.

Abstract
Extensive population-based genome-wide association studies have identified an association between the FTO gene and BMI; however, the mechanism of action is still unknown. To determine whether FTO may influence weight regulation through psychological and behavioral factors, seven single-nucleotide polymorphisms (SNPs) of the FTO gene were genotyped in 1,085 individuals with anorexia nervosa (AN) and 677 healthy weight controls from the international Price Foundation Genetic Studies of Eating Disorders. Each SNP was tested in association with eating disorder phenotypes and measures that have previously been associated with eating behavior pathology: trait anxiety, harm-avoidance, novelty seeking, impulsivity, obsessionality, compulsivity, and concern over mistakes. After appropriate correction for multiple comparisons, no significant associations between individual FTO gene SNPs and eating disorder phenotypes or related eating behavior pathology were identified in cases or controls. Thus, this study found no evidence that FTO gene variants associated with weight regulation in the general population are associated with eating disorder phenotypes in AN participants or matched controls.

Abstract
CONTEXT Many youth with depression do not respond to initial treatment with selective serotonin reuptake inhibitors (SSRIs), and this is associated with higher costs. More effective treatment for these youth may be cost-effective. OBJECTIVE To evaluate the incremental cost-effectiveness over 24 weeks of combined cognitive behavior therapy plus switch to a different antidepressant medication vs medication switch only in adolescents who continued to have depression despite adequate initial treatment with an SSRI. DESIGN Randomized controlled trial. SETTING Six US academic and community clinics. PATIENTS Three hundred thirty-four patients aged 12 to 18 years with SSRI-resistant depression. INTERVENTION Participants were randomly assigned to (1) switch to a different medication only or (2) switch to a different medication plus cognitive behavior therapy. MAIN OUTCOME MEASURES Clinical outcomes were depression-free days (DFDs), depression-improvement days (DIDs), and quality-adjusted life-years based on DFDs (DFD-QALYs). Costs of intervention, nonprotocol services, and families were included. RESULTS Combined treatment achieved 8.3 additional DFDs (P = .03), 0.020 more DFD-QALYs (P = .03), and 11.0 more DIDs (P = .04). Combined therapy cost $1633 more (P = .01). Cost per DFD was $188 (incremental cost-effectiveness ratio [ICER] = $188; 95% confidence interval [CI], -$22 to $1613), $142 per DID (ICER = $142; 95% CI, -$14 to $2529), and $78,948 per DFD-QALY (ICER = $78,948; 95% CI, -$9261 to $677,448). Cost-effectiveness acceptability curve analyses suggest a 61% probability that combined treatment is more cost-effective at a willingness to pay $100,000 per QALY. Combined treatment had a higher net benefit for subgroups of youth without a history of abuse, with lower levels of hopelessness, and with comorbid conditions. CONCLUSIONS For youth with SSRI-resistant depression, combined treatment decreases the number of days with depression and is more costly. Depending on a decision maker's willingness to pay, combined therapy may be cost-effective, particularly for some subgroups. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00018902.

Abstract
OBJECTIVE We investigated the sociodemographic characteristics in women with and without lifetime eating disorders. METHOD Participants were from a multisite international study of eating disorders (N = 2,096). Education level, relationship status, and reproductive status were examined across eating disorder subtypes and compared with a healthy control group. RESULTS Overall, women with eating disorders were less educated than controls, and duration of illness and age of onset were associated with educational attainment. Menstrual status was associated with both relationship and reproductive status, but eating disorder subtypes did not differ significantly from each other or from healthy controls on these dimensions. DISCUSSION Differences in educational attainment, relationships, and reproduction do exist in individuals with eating disorders and are differentially associated with various eating disorder symptoms and characteristics. These data could assist in educating patients and family members about long-term consequences of eating disorders.

Abstract
BACKGROUND We examined the long-term outcome of participants in the Treatment of SSRI-Resistant Depression in Adolescents (TORDIA) study, a randomized trial of 334 adolescents (aged 12-18 years) with DSM-IV-defined major depressive disorder initially resistant to selective serotonin reuptake inhibitor (SSRI) treatment who were subsequently treated for 12 weeks with another SSRI, venlafaxine, another SSRI + cognitive-behavioral therapy (CBT), or venlafaxine + CBT. Responders then continued with the same treatment through week 24, while nonresponders were given open treatment. METHOD For the current study, patients were reassessed 48 (n = 116) and 72 (n = 130) weeks from intake. Data were gathered from February 2001 to February 2007. Standardized diagnostic interviews and measures of depression, suicidal ideation, related psychopathology, and level of functioning were periodically administered. Remission was defined as ≥ 3 weeks with ≤ 1 clinically significant symptom and no associated functional impairment (score of 1 on the adolescent version of the Longitudinal Interval Follow-Up Evaluation [A-LIFE]), and relapse, as ≥ 2 weeks with probable or definite depressive disorder (score of 3 or 4 on the A-LIFE). Mixed-effects regression models were applied to estimate remission, relapse, and functional recovery. RESULTS By 72 weeks, an estimated 61.1% of the randomized youths had reached remission. Randomly assigned treatment (first 12 weeks) did not influence remission rate or time to remission, but the group assigned to SSRIs had a more rapid decline in self-reported depressive symptoms and suicidal ideation than those assigned to venlafaxine (P < .03). Participants with more severe depression, greater dysfunction, and alcohol or drug use at baseline were less likely to remit. The depressive symptom trajectory of the remitters diverged from that of nonremitters by the first 6 weeks of treatment (P < .001). Of the 130 participants in remission at week 24, 25.4% relapsed in the subsequent year. CONCLUSIONS While most adolescents achieved remission, more than one-third did not, and one-fourth of remitted patients experienced a relapse. More effective interventions are needed for patients who do not show robust improvement early in treatment. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00018902.

Abstract
We studied the relation between intrusive and repetitive hair pulling, the defining feature of trichotillomania, and compulsive and impulsive features in 1,453 individuals with anorexia nervosa and bulimia nervosa. We conducted a series of regression models examining the relative influence of compulsive features associated with obsessive-compulsive disorder, compulsive features associated with eating disorders, trait features related to harm avoidance, perfectionism, and novelty seeking, and self harm. A final model with a reduced sample (n = 928) examined the additional contribution of impulsive attributes. One of 20 individuals endorsed hair pulling. Evidence of a positive association with endorsement of compulsive behavior of the obsessive-compulsive spectrum emerged. Hair pulling may be more consonant with ritualistic compulsions than impulsive urges in those with eating disorders.

Abstract
One of the primary facets of borderline personality disorder (BPD) is behavioral dysregulation, a wide array of behaviors that are difficult to control and harmful to the individual. The purpose of this study was to explore the association between BPD and a variety of dysregulated behaviors, some of which have received little empirical attention. Using a large sample of individuals diagnosed with anorexia nervosa, 41 individuals diagnosed with BPD were compared to the rest of the sample on the presence of dysregulated behaviors using logistic regression analyses. Anorexia nervosa subtypes, age, and other Cluster B personality disorders were used as covariates. Results support an association between BPD and alcohol misuse, hitting someone/breaking things, provoking fights/arguments, self-injury, overdosing, street drug use, binge-eating, impulsive spending, shoplifting/stealing, and risky sexual behaviors. Differences between dichotomous and continuous measures of BPD yielded somewhat different results. Information on co-occurring anorexia nervosa and BPD was generated.

Abstract
BACKGROUND The purpose of this study is to examine the prevalence and correlates of non-suicidal self-injury (NSSI) among children and adolescents diagnosed with bipolar disorder (BP). METHODS Four hundred-thirty two youth with a diagnosis of BP and their parents, including 193 children and 239 adolescents, completed a diagnostic interview and instruments to assess youth clinical and illness history, youth comorbidity, parental mood disorder, and psychosocial functioning. RESULTS Approximately 22% of children and 22% of adolescents reported NSSI during the course of their most recent mood episode. In a multivariate model controlling for global impairment, among children, a BPI or BPII diagnosis (versus BPNOS), psychosis, separation anxiety disorder, and greater severity of depressive symptoms were found to be associated with NSSI. Among adolescents, a mixed episode, a suicide attempt, greater severity of depressive symptoms, and poor psychosocial functioning were found to be associated with NSSI. Neither the presence of a youth comorbid disruptive behavior disorder nor a parental mood disorder was associated with NSSI. LIMITATIONS The primary limitations of this study include the use of a cross-sectional study design, lack of a control group, and limited generalizability of study results to non-clinical and ethnically diverse samples. CONCLUSIONS NSSI is not uncommon among youth with BP, particularly those who present with BPI or BPII, psychosis, a mixed episode, suicidal behavior, severe depressive symptoms, separation anxiety, and/or poor psychosocial functioning. However, the relative importance of these factors in relation to NSSI may vary with age. Treatments for BP that are developmentally sensitive, examine the function of NSSI for each youth, and teach adaptive skills to address emotional and social needs, may prove to be most successful.

Abstract
OBJECTIVE The purpose of this study was to report on the outcome of participants in the Treatment of Resistant Depression in Adolescents (TORDIA) trial after 24 weeks of treatment, including remission and relapse rates and predictors of treatment outcome. METHOD Adolescents (ages 12-18 years) with selective serotonin reuptake inhibitor (SSRI)-resistant depression were randomly assigned to either a medication switch alone (alternate SSRI or venlafaxine) or a medication switch plus cognitive-behavioral therapy (CBT). At week 12, responders could continue in their assigned treatment arm and nonresponders received open treatment (medication and/or CBT) for 12 more weeks (24 weeks total). The primary outcomes were remission and relapse, defined by the Adolescent Longitudinal Interval Follow-Up Evaluation as rated by an independent evaluator. RESULTS Of 334 adolescents enrolled in the study, 38.9% achieved remission by 24 weeks, and initial treatment assignment did not affect rates of remission. Likelihood of remission was much higher (61.6% versus 18.3%) and time to remission was much faster among those who had already demonstrated clinical response by week 12. Remission was also higher among those with lower baseline depression, hopelessness, and self-reported anxiety. At week 12, lower depression, hopelessness, anxiety, suicidal ideation, family conflict, and absence of comorbid dysthymia, anxiety, and drug/alcohol use and impairment also predicted remission. Of those who responded by week 12, 19.6% had a relapse of depression by week 24. CONCLUSIONS Continued treatment for depression among treatment-resistant adolescents results in remission in approximately one-third of patients, similar to adults. Eventual remission is evident within the first 6 weeks in many, suggesting that earlier intervention among nonresponders could be important.

Abstract
Anorexia nervosa (AN) is perhaps the most lethal mental disorder, in part due to starvation-related health problems, but especially because of high suicide rates. One potential reason for high suicide rates in AN may be that those affected face pain and provocation on many fronts, which may in turn reduce their fear of pain and thereby increase risk for death by suicide. The purpose of the following studies was to explore whether repetitive exposure to painful and destructive behaviors such as vomiting, laxative use, and non-suicidal self-injury (NSSI) was a mechanism that linked AN-binge-purging (ANBP) subtype, as opposed to AN-restricting subtype (ANR), to extreme suicidal behavior. Study 1 utilized a sample of 787 individuals diagnosed with one or the other subtype of AN, and structural equation modeling results supported provocative behaviors as a mechanism linking ANBP to suicidal behavior. A second, unexpected mechanism emerged linking ANR to suicidal behavior via restricting. Study 2, which used a sample of 249 AN patients, replicated these findings, including the second mechanism linking ANR to suicide attempts. Two potential routes to suicidal behavior in AN appear to have been identified: one route through repetitive experience with provocative behaviors for ANBP, and a second for exposure to pain through the starvation of restricting in ANR.

Abstract
We performed association studies with 5,151 SNPs that were judged as likely candidate genetic variations conferring susceptibility to anorexia nervosa (AN) based on location under reported linkage peaks, previous results in the literature (182 candidate genes), brain expression, biological plausibility, and estrogen responsivity. We employed a case-control design that tested each SNP individually as well as haplotypes derived from these SNPs in 1,085 case individuals with AN diagnoses and 677 control individuals. We also performed separate association analyses using three increasingly restrictive case definitions for AN: all individuals with any subtype of AN (All AN: n = 1,085); individuals with AN with no binge eating behavior (AN with No Binge Eating: n = 687); and individuals with the restricting subtype of AN (Restricting AN: n = 421). After accounting for multiple comparisons, there were no statistically significant associations for any individual SNP or haplotype block with any definition of illness. These results underscore the importance of large samples to yield appropriate power to detect genotypic differences in individuals with AN and also motivate complementary approaches involving Genome-Wide Association (GWA) studies, Copy Number Variation (CNV) analyses, sequencing-based rare variant discovery assays, and pathway-based analysis in order to make up for deficiencies in traditional candidate gene approaches to AN.

Abstract
OBJECTIVE To describe sexual functioning in women with eating disorders. METHOD We assessed physical intimacy, libido, sexual anxiety, partner status, and sexual relationships in 242 women from the International Price Foundation Genetic Studies relative to normative data. RESULTS Intercourse (55.3%), having a partner (52.7%), decreased sexual desire (66.9%), and increased sexual anxiety (59.2%) were common. Women with restricting and purging anorexia nervosa had a higher prevalence of loss of libido than women with bulimia nervosa and eating disorder not otherwise specified (75%, 74.6%, 39%, and 45.4%, respectively). Absence of sexual relationships was associated with lower minimum lifetime body mass index (BMI) and earlier age of onset; loss of libido with lower lifetime BMI, higher interoceptive awareness and trait anxiety; and sexual anxiety with lower lifetime BMI, higher harm avoidance and ineffectiveness. Sexual dysfunction in eating disorders was higher than in the normative sample. DISCUSSION Sexual dysfunction is common across eating disorders subtypes. Low BMI is associated with loss of libido, sexual anxiety, and avoidance of sexual relationships.

Abstract
OBJECTIVE We examined prevalence of substance use disorders (SUD) in women with: (1) anorexia nervosa (AN) restricting type (RAN); (2) AN with purging only (PAN); (3) AN with binge eating only (BAN); and (4) lifetime AN and bulimia nervosa (ANBN). Secondary analyses examined SUD related to lifetime purging behavior and lifetime binge eating. METHOD Participants (N = 731) were drawn from the International Price Foundation Genetic Studies. RESULTS The prevalence of SUD differed across AN subtypes, with more in the ANBN group reporting SUD than those in the RAN and PAN groups. Individuals who purged were more likely to report substance use than those who did not purge. Prevalence of SUD differed across lifetime binge eating status. DISCUSSION SUD are common in AN and are associated with bulimic symptomatology. Results underscore the heterogeneity in AN, highlighting the importance of screening for SUD across AN subtypes.

Abstract
OBJECTIVE Extremely low body mass index (BMI) values are associated with increased risk for death and poor long-term prognosis in individuals with anorexia nervosa (AN). The present study explores childhood personality characteristics that could be associated with the ability to attain an extremely low BMI. METHODS Participants were 326 women from the Genetics of Anorexia Nervosa (GAN) Study who completed the Structured Interview for Anorexia Nervosa and Bulimic Syndromes and whose mother completed the Child Behavioral Checklist and/or Revised Dimensions of Temperament Survey. RESULTS Children who were described as having greater fear or anxiety by their mothers attained lower BMIs during AN (p < 0.02). Path analysis in the GAN and a validation sample, Price Foundation Anorexia Nervosa Trios Study, confirmed the relation between early childhood anxiety, caloric restriction, qualitative food item restriction, excessive exercise, and low BMI. Path analysis also confirmed a relation between childhood anxiety and caloric restriction, which mediated the relation between childhood anxiety and low BMI in the GAN sample only. CONCLUSION Fearful or anxious behavior as a child was associated with the attainment of low BMI in AN and childhood anxiety was associated with caloric restriction. Measures of anxiety and factors associated with anxiety-proneness in childhood may index children at risk for restrictive behaviors and extremely low BMIs in AN.

Abstract
OBJECTIVE The authors sought to assess the longitudinal course of youths with bipolar spectrum disorders over a 4-year period. METHOD At total of 413 youths (ages 7-17 years) with bipolar I disorder (N=244), bipolar II disorder (N=28), and bipolar disorder not otherwise specified (N=141) were enrolled in the study. Symptoms were ascertained retrospectively on average every 9.4 months for 4 years using the Longitudinal Interval Follow-Up Evaluation. Rates and time to recovery and recurrence and week-by-week symptomatic status were analyzed. RESULTS Approximately 2.5 years after onset of their index episode, 81.5% of the participants had fully recovered, but 1.5 years later 62.5% had a syndromal recurrence, particularly depression. One-third of the participants had one syndromal recurrence, and 30% had two or more. The polarity of the index episode predicted that of subsequent episodes. Participants were symptomatic during 60% of the follow-up period, particularly with subsyndromal symptoms of depression and mixed polarity, with numerous changes in mood polarity. Manic symptomatology, especially syndromal, was less frequent, and bipolar II was mainly manifested by depressive symptoms. Overall, 40% of the participants had syndromal or subsyndromal symptoms during 75% of the follow-up period, and 16% of the participants experienced psychotic symptoms during 17% the follow-up period. Twenty-five percent of youths with bipolar II converted to bipolar I, and 38% of those with bipolar disorder not otherwise specified converted to bipolar I or II. Early onset, diagnosis of bipolar disorder not otherwise specified, long illness duration, low socioeconomic status, and family history of mood disorders were associated with poorer outcomes. CONCLUSIONS Bipolar spectrum disorders in youths are characterized by episodic illness with subsyndromal and, less frequently, syndromal episodes with mainly depressive and mixed symptoms and rapid mood changes.

Abstract
OBJECTIVE The authors sought to identify predictors of self-harm adverse events in treatment-resistant, depressed adolescents during the first 12 weeks of treatment. METHOD Depressed adolescents (N=334) who had not responded to a previous trial with an SSRI antidepressant were randomized to a switch to either another SSRI or venlafaxine, with or without cognitive behavior therapy. Self-harm events, i.e., suicidal and non-suicidal self-injury adverse events were assessed by spontaneous report for the first 181 participants, and by systematic weekly assessment for the last 153 participants. RESULTS Higher rates of suicidal (20.8% vs. 8.8%) and nonsuicidal self-injury (17.6% vs. 2.2%), but not serious adverse events (8.4% vs. 7.3%) were detected with systematic monitoring. Median time to a suicidal event was 3 weeks, predicted by high baseline suicidal ideation, family conflict, and drug and alcohol use. Median time to nonsuicidal self-injury was 2 weeks, predicted by previous history of nonsuicidal self-injury. While there were no main effects of treatment, venlafaxine treatment was associated with a higher rate of self-harm adverse events in those with higher suicidal ideation. Adjunctive use of benzodiazepines, while in a small number of participants (N=10) was associated with higher rate of both suicidal and nonsuicidal self-injury adverse events. CONCLUSIONS Since predictors of suicidal adverse events also predict poor response to treatment, and many of these events occurred early in treatment, improving the speed of response to depression, by targeting of family conflict, suicidal ideation, and drug use may help to reduce their incidence. The relationship of venlafaxine and of benzodiazepines to self-harm events requires further study and clinical caution.

Abstract
BACKGROUND Anorexia nervosa (AN) is associated with behavioral traits that predate the onset of AN and persist after recovery. We identified patterns of behavioral traits in AN trios (proband plus two biological parents). METHOD A total of 433 complete trios were collected in the Price Foundation Genetic Study of AN using standardized instruments for eating disorder (ED) symptoms, anxiety, perfectionism, and temperament. We used latent profile analysis and ANOVA to identify and validate patterns of behavioral traits. RESULTS We distinguished three classes with medium to large effect sizes by mothers' and probands' drive for thinness, body dissatisfaction, perfectionism, neuroticism, trait anxiety, and harm avoidance. Fathers did not differ significantly across classes. Classes were distinguished by degree of symptomatology rather than qualitative differences. Class 1 (approximately 33%) comprised low symptom probands and mothers with scores in the healthy range. Class 2 ( approximately 43%) included probands with marked elevations in drive for thinness, body dissatisfaction, neuroticism, trait anxiety, and harm avoidance and mothers with mild anxious/perfectionistic traits. Class 3 (approximately 24%) included probands and mothers with elevations on ED and anxious/perfectionistic traits. Mother-daughter symptom severity was related in classes 1 and 3 only. Trio profiles did not differ significantly by proband clinical status or subtype. CONCLUSIONS A key finding is the importance of mother and daughter traits in the identification of temperament and personality patterns in families affected by AN. Mother-daughter pairs with severe ED and anxious/perfectionistic traits may represent a more homogeneous and familial variant of AN that could be of value in genetic studies.

Abstract
OBJECTIVE To compare the most severe lifetime (current or past) mood symptoms, duration of illness, and rates of lifetime comorbid disorders among youth with bipolar spectrum disorders [BP (bipolar-I, bipolar-II and bipolar-not otherwise specified)]. METHODS A total of 173 children (<12 years) with BP, 101 adolescents with childhood-onset BP, and 90 adolescents with adolescent-onset BP were evaluated with standardized instruments. RESULTS Depression was the most common initial and frequent episode for both adolescent groups, followed by mania/hypomania. Adolescents with childhood-onset BP had the longest illness, followed by children and then adolescents with adolescent-onset BP. Adjusting for sex, socioeconomic status, and duration of illness, while manic, both adolescent groups showed more 'typical' and severe manic symptoms. Mood lability was more frequent in childhood-onset and adolescents with early-onset BP. While depressed, both adolescent groups showed more severe depressive symptoms, higher rates of melancholic and atypical symptoms, and suicide attempts than children. Depressed children had more severe irritability than depressed adolescents. Early BP onset was associated with attention-deficit hyperactivity disorder, whereas later BP onset was associated with panic, conduct, and substance use disorders. Above-noted results were similar when each BP subtype was analyzed separately. CONCLUSIONS Older age was associated with more severe and typical mood symptomatology. However, there were differences and similarities in type, intensity, and frequency of BP symptoms and comorbid disorders related to age of onset and duration of BP and level of psychosocial development. These factors and the normal difficulties youth have expressing and modulating their emotions may explain existing complexities in diagnosing and treating BP in youth, particular in young children, and suggest the need for developmentally sensitive treatments.

Abstract
OBJECTIVES Previous studies have suggested that the sum of Attention, Aggression, and Anxious/Depressed subscales of Child Behavior Checklist (CBCL-PBD; pediatric bipolar disorder phenotype) may be specific to pediatric bipolar disorder (BP). The purpose of this study was to evaluate the usefulness of the CBCL and CBCL-PBD to identify BP in children <12 years old. METHODS A sample of children with BP I, II, and not otherwise specified (NOS) (n = 157) ascertained through the Course and Outcome for Bipolar Disorder in Youth (COBY) study were compared with a group of children with major depressive/anxiety disorders (MDD/ANX; n = 101), disruptive behavior disorder (DBD) (n = 127), and healthy control (HC) (n = 128). The CBCL T-scores and area under the curve (AUC) scores were calculated and compared among the above-noted groups. RESULTS Forty one percent of BP children did not have significantly elevated CBCL-PBD scores (>or=2 standard deviations [SD]). The sensitivity and specificity of CBCL-PBD >or= 2 SD for diagnosis of BP was 57% and 70-77%, respectively, and the accuracy of CBCL-PBD for identifying a BP diagnosis was moderate (AUC = 0.72-0.78). CONCLUSION The CBCL and the CBCL-PBD showed that BP children have more severe psychopathology than HC and children with other psychopathology, but they were not useful as a proxy for Diagnostic and Statistical Manual of Mental Disorders, 4(th) edition (DSM-IV) diagnosis of BP.

Abstract
OBJECTIVE Childhood anxiety often precedes the onset of anorexia nervosa (AN) and may mark a liability to the emergence of an eating disorder for some women. This study investigates the prevalence of overanxious disorder (OAD) among women with AN and explores how OAD impacts AN symptoms and personality traits. METHOD Participants were 637 women with AN who completed an eating disorders history, the Structured Clinical Interview for DSM-IV Axis I Disorders, and assessments for childhood anxiety, eating disorder attitudes, and associated personality traits. RESULTS Of 249 women (39.1%) reporting a history of OAD, 235 (94.4%) met criteria for OAD before meeting criteria for AN. In comparison to those without OAD, women with AN and OAD self-reported more extreme personality traits and attitudes and they engaged in more compensatory behaviors. CONCLUSION Among individuals with AN, those entering AN on a pathway via OAD present with more severe eating disorder pathology.

Abstract
OBJECTIVE Supported by National Institute of Mental Health (NIMH), this 12-site international collaboration seeks to identify genetic variants that affect risk for anorexia nervosa (AN). METHOD Four hundred families will be ascertained with two or more individuals affected with AN. The assessment battery produces a rich set of phenotypes comprising eating disorder diagnoses and psychological and personality features known to be associated with vulnerability to eating disorders. RESULTS We report attributes of the first 200 families, comprising 200 probands and 232 affected relatives. CONCLUSION These results provide context for the genotyping of the first 200 families by the Center for Inherited Disease Research. We will analyze our first 200 families for linkage, complete recruitment of roughly 400 families, and then perform final linkage analyses on the complete cohort. DNA, genotypes, and phenotypes will form a national eating disorder repository maintained by NIMH and available to qualified investigators.

Abstract
CONTEXT Only about 60% of adolescents with depression will show an adequate clinical response to an initial treatment trial with a selective serotonin reuptake inhibitor (SSRI). There are no data to guide clinicians on subsequent treatment strategy. OBJECTIVE To evaluate the relative efficacy of 4 treatment strategies in adolescents who continued to have depression despite adequate initial treatment with an SSRI. DESIGN, SETTING, AND PARTICIPANTS Randomized controlled trial of a clinical sample of 334 patients aged 12 to 18 years with a primary diagnosis of major depressive disorder that had not responded to a 2-month initial treatment with an SSRI, conducted at 6 US academic and community clinics from 2000-2006. INTERVENTIONS Twelve weeks of: (1) switch to a second, different SSRI (paroxetine, citalopram, or fluoxetine, 20-40 mg); (2) switch to a different SSRI plus cognitive behavioral therapy; (3) switch to venlafaxine (150-225 mg); or (4) switch to venlafaxine plus cognitive behavioral therapy. MAIN OUTCOME MEASURES Clinical Global Impressions-Improvement score of 2 or less (much or very much improved) and a decrease of at least 50% in the Children's Depression Rating Scale-Revised (CDRS-R); and change in CDRS-R over time. RESULTS Cognitive behavioral therapy plus a switch to either medication regimen showed a higher response rate (54.8%; 95% confidence interval [CI], 47%-62%) than a medication switch alone (40.5%; 95% CI, 33%-48%; P = .009), but there was no difference in response rate between venlafaxine and a second SSRI (48.2%; 95% CI, 41%-56% vs 47.0%; 95% CI, 40%-55%; P = .83). There were no differential treatment effects on change in the CDRS-R, self-rated depressive symptoms, suicidal ideation, or on the rate of harm-related or any other adverse events. There was a greater increase in diastolic blood pressure and pulse and more frequent occurrence of skin problems during venlafaxine than SSRI treatment. CONCLUSIONS For adolescents with depression not responding to an adequate initial treatment with an SSRI, the combination of cognitive behavioral therapy and a switch to another antidepressant resulted in a higher rate of clinical response than did a medication switch alone. However, a switch to another SSRI was just as efficacious as a switch to venlafaxine and resulted in fewer adverse effects. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00018902.

Abstract
OBJECTIVE To compare patterns of recovery in individuals with index episodes of anorexia nervosa (AN) and bulimia nervosa (BN). METHOD Using Kaplan-Meier methods and Cox proportional hazards models, comparisons were conducted that were conditional on duration of eating disorder from onset and included a conservative recovery criterion of 3 asymptomatic years. Data collection was retrospective and from two of the international Price Foundation genetic studies on 901 individuals with eating disorders. RESULTS Using Kaplan-Meier methods, 11% of those with index AN and 10% of those with index BN met recovery criteria at 10 years. At 15 years, 16% of those with index AN and 25% of those with index BN met recovery criteria. In a Cox proportional hazards model the index BN group had three times the rate of recovery at 10-14 years (p=0.01) than the index AN group. CONCLUSIONS Initially the probability of recovery was greater for those with index AN, but as the duration of the eating disorder lengthened those with BN had higher probabilities of recovery. Replication of these results with prospective data using similarly stringent recovery criteria and methods is required to confirm trends.

Abstract
We compared symptom patterns, severity of illness, and comorbidity in individuals with eating disorders with and without impulse control disorders (ICD), and documented the temporal pattern of illness onset. Lifetime ICD were present in 16.6% of 709 women with a history of eating disorders. The most common syndromes were compulsive buying disorder and kleptomania. ICD occurred more in individuals with binge eating subtypes, and were associated with significantly greater use of laxatives, diuretics, appetite suppressants and fasting, and with greater body image disturbance, higher harm avoidance, neuroticism, cognitive impulsivity, and lower self-directedness. In addition, individuals with ICD were more likely to have obsessive-compulsive disorder, any anxiety disorder, specific phobia, depression, cluster B personality disorder, avoidant personality disorder, and to use psychoactive substances. Among those with ICD, 62% reported the ICD predated the eating disorder and 45% reported the onset of both disorders within the same 3-year window. The presence of a lifetime ICD appears to be limited to eating disorders marked by binge eating and to be associated with worse eating-related psychopathology, more pathological personality traits, and more frequent comorbid Axis I and II conditions. Untreated ICD may complicate recovery from eating disorders.
