  <detailed_description>
    <textblock>
      The increasing prevalence of eating disorders in adolescence and their frequent chronic&#xD;
      course have led to the development of various programs for prevention, early detection and&#xD;
      early intervention. Nevertheless, the causes of anorexia nervosa (AN) and bulimia nervosa&#xD;
      (BN) remain a topic of much discussion and research. Evidence points to a multifactorial&#xD;
      disease pattern in which intrapsychic, psychosocial and biological factors interact and&#xD;
      reinforce one another. Eating disorders have been increasingly associated with signs of&#xD;
      emotional and psychological disturbance. In clinical populations, personality traits are&#xD;
      observed as exacerbating factors that constitute important variables for differentiation.&#xD;
      While investigations have shown high comorbidity of personality disorders and eating&#xD;
      disorders in adulthood, comparable studies in adolescence have not yet been undertaken.&#xD;
&#xD;
      The proposed study will investigate whether, on the basis of personality traits and&#xD;
      personality disorders as well as specific cerebral activation patterns, differentiations can&#xD;
      be identified among adolescent female patients with AN (n = 50) and BN (n = 30) in comparison&#xD;
      to a healthy control group (n = 30).&#xD;
&#xD;
      Of particular interest is the potential connection between specific personality traits and&#xD;
      neural correlates in the two ED:&#xD;
&#xD;
        1. Do specific personality traits and personality disorders correlate significantly with&#xD;
           particular types of ED?&#xD;
&#xD;
        2. Do AN and BN correlate significantly with particular cerebral activation patterns&#xD;
           following visual presentation of food stimuli and gustatory stimuli? 3. Can connections&#xD;
           be identified between specific personality profiles and cerebral activation patterns in&#xD;
           AN and BN? 4. Will changes in cerebral activation patterns be evident between the&#xD;
           beginning of treatment (T1) and the end of treatment (T2)? The study will use specific&#xD;
           questionnaires dealing with eating behavior (EDI &amp; EAT) as well as clinical interviews&#xD;
           for the assessment of personality disorders (SCID II). Cerebral processing will be&#xD;
           evaluated using functional MRI (fMRI) and structural MRI. fMRI results from visual and&#xD;
           gustatory stimuli will be correlated with structural brain morphology in MRI and with&#xD;
           psychopathological parameters. The correlation of such clinical values represents a new&#xD;
           approach to the investigation of eating disorders in adults and may be of significant&#xD;
           relevance for data interpretation and understanding of cerebral changes due to anorexia.&#xD;
           MRI measurements will be performed at begin of therapy (T1) and at end of therapy (T2).&#xD;
&#xD;
      In this fashion, known risk factors will be supplemented with information on specific&#xD;
      personality traits and cerebral activation patterns. The proposed study will thus provide&#xD;
      important new insights for early detection, prevention, treatment and clinical assessment.&#xD;

For adolescents older than 16.11 years, we will use the German version of the Wechsler Adult Intelligence Scale (HAWIE-IV).Results from test-retest reliability demonstrate that the mean retest scores for all subtests are higher than the mean test scores from first administration, with effect sizes ranging from .08 (comprehension) to .60 (picture completion). The test has demonstrated an acceptable relationship to other measures of achievement, memory, adaptive behavior, emotional intelligence and giftedness in children and adolescents (Canivez, 2014). For the non-clinical adolescent sample, we will use two subtests of the HAWIK.</description>

    <description>To measure food-related brain activation, event-related fMRI will be used, with phases of high-caloric images alternating with phases of low-caloric images and images of fixation cross (not related to food images). A total of 18 blocks will be performed - see figure below. The duration of each phase will be 30 seconds. In a second run, the patients and control subjects will drink chocolate milk and water, alternating every 30 seconds, through a long silicon tube. This procedure was successfully tested in a previous fMRI study with adult AN patients (Gizewski et al. 2010, Vocks et al. 2011) and has now been adopted in preliminary measurements for young AN patients.</description>

      While investigations have shown high comorbidity of personality disorders and eating

      be identified among adolescent female patients with AN (n = 50) and BN (n = 30) in comparison

      Of particular interest is the potential connection between specific personality traits and
      neural correlates in the two ED:

        1. Do specific personality traits and personality disorders correlate significantly with

intervention name: SCID-II
description: The SCID-II interview (German, see Wittchen, Zaudig & Fydrich, 1997) is a widely used and researched instrument to assess DSM-IV-TR personality disorders.The interview covers all ten DSM-IV personality disorders (antisocial, avoidant, borderline, dependent, histrionic, narcissistic, obsessive-compulsive, paranoid, schizoid and schizotypal), PD not otherwise specified, and appendix categories (depressive PD and passive-aggressive PD) and is used to make personality disorder diagnoses either dimensionally or categorically (present-absent). Furthermore, it allows the investigation of patterns of PD that co-occur with other mental disorders as well as the analysis of the underlying structure of personality pathology.

intervention name: LoPF
description: In order to specifically focus on certain personality traits, we use the LoPF as an additional measure. It is a well-validated and reliable self-report questionnaire to measure healthy and pathological personality functioning in adolescents. It is based on the DSM-5 Section III Alternative Model for Personality disorders and covers core impairments in adolescents' personality functioning: identity, self-direction (self-related personality functioning), intimacy/ attachment and empathy/ social-related personality functioning (Sevecke & Krischer, 2011).

intervention name: HAWIK-IV
description: The Wechsler Intelligence Scale for Children (HAWIK-IV, Petermann & Petermann, 2008) will be used assess intelligence. For adolescents older than 16.11 years, we will use the German version of the Wechsler Adult Intelligence Scale (HAWIE-IV).Results from test-retest reliability demonstrate that the mean retest scores for all subtests are higher than the mean test scores from first administration, with effect sizes ranging from .08 (comprehension) to .60 (picture completion). The test has demonstrated an acceptable relationship to other measures of achievement, memory, adaptive behavior, emotional intelligence and giftedness in children and adolescents (Canivez, 2014). For the non-clinical adolescent sample, we will use two subtests of the HAWIK.

intervention name: fMRI
description: To measure food-related brain activation, event-related fMRI will be used, with phases of high-caloric images alternating with phases of low-caloric images and images of fixation cross (not related to food images). A total of 18 blocks will be performed - see figure below. The duration of each phase will be 30 seconds. In a second run, the patients and control subjects will drink chocolate milk and water, alternating every 30 seconds, through a long silicon tube. This procedure was successfully tested in a previous fMRI study with adult AN patients (Gizewski et al. 2010, Vocks et al. 2011) and has now been adopted in preliminary measurements for young AN patients.
