BackgroundPersonality pathology constitutes a major form of psychopathology in adolescents.AimsTo examine the reliability and validity of a Q-sort instrument for assessing adolescent personality pathology designed for clinically experienced informants.MethodA sample of 294 randomly selected psychiatrists and psychologists each provided data on a current patient, aged 14–18 years. Clinicians completed several measures, including the Shedler–Westen Assessment Procedure for Adolescents (SWAP–200–A).ResultsFactor analysis identified II dimensions of adolescent personality: psychopathology/malignant narcissism, dysphoria/inhibition, psychological health, histrionic sexualisation, schizotypy, sexual conflict, emotional dysregulation, anxious obsessionality, peer rejection, delinquent behaviour and attentional dysregulation. These correlated in predicted ways with a range of criterion variables, including measures of adaptive functioning, Axis II pathology, the Five Factor Model and the Child Behavior Checklist.ConclusionsThe SWAP–200–A shows promise as an instrument for assessing personality pathology in adolescents. Trait dimensions such as delinquent behaviour and emotional dysregulation may prove useful additions to a classification of personality.

Current research has established that male adolescents with illegal sexual behavior (AISB) are a heterogeneous population. We aimed to explore this within-group heterogeneity to derive clinically relevant groups of AISB using the Millon Adolescent Clinical Inventory (MACI). We then compared these groups on selected covariates (age at intake, minority status, and child maltreatment history) and distal outcomes (general, nonviolent, violent, drug, and sexual recidivism 5 years after release) to identify any differences. The sample consisted of 698 male AISB (age = 11-20 years) referred to a secure juvenile facility for assessment and treatment. A latent profile analysis (LPA) was conducted using the clinical and personality scales of the MACI to identify AISB groups and examine group differences. Four unique AISB groups emerged: Anxious, Depressed/Anxious, Dysthymic/Disorganized, and Antisocial. Groups differed on age at intake and child maltreatment history, but not minority status. At 5-year follow up, groups differed in their rates of general, nonsexual, and violent recidivism but not in their rates of sexual or drug recidivism. Clinically relevant AISB groups can be identified using personality and psychopathology indicators from the MACI. Implications for the assessment and treatment of AISB, as well as directions for future research are discussed.

Socioeconomic position, racial/ethnic minority status, and other characteristics of the macro-environment may be important moderators of genetic influence on a wide array of psychosocial outcomes. Designed to maximize representation of low socioeconomic status families and racial/ethnic minorities, the Texas Twin Project is an ongoing study of school-age twins (preschool through 12th grade) enrolled in public schools in the Austin, Texas and Houston, Texas metropolitan areas. School rosters are used to identify twin families from a target population with sizable populations of African American (18%), Hispanic/Latino (48%), and non-Hispanic White (27%) children and adolescents, over half of whom meet US guidelines for classification as economically disadvantaged. Initial efforts have focused on a large-scale, family-based survey study involving both parent and child reports of personality, psychopathology, physical health, academic interests, parent–child relationships, and aspects of the home environment. In addition, the Texas Twin Project is the basis for an in-laboratory study of adolescent decision-making, delinquency, and substance use. Future directions include geographic expansion of the sample to the entire state of Texas (with a population of over 25 million) and genotyping of participating twins.

BackgroundThere is a debate over whether disruptive behaviour should be regarded as a central component of, or rather as an epiphenomenon with little diagnostic value for, psychopathy.AimsTo test whether callous–unemotional traits and conduct disorder can be dissociated in the English and Romanian Adoptee Study, a prospective longitudinal study of adopted individuals with a history of severe early institutional deprivation.MethodThe Child and Adolescent Psychiatric Assessment was used to establish DSM-IV diagnoses for conduct disorder (and also oppositional defiant disorder) at the 15-year follow-up stage. The Inventory of Callous–Unemotional Traits questionnaire was administered to assess psychopathy traits.ResultsThere was no significant association between callous–unemotional traits and conduct disorder, both according to parent and youth self-report assessed categorically and dimensionally after controlling for confounds.ConclusionsThe majority of individuals with high callous–unemotional traits did not show conduct disorder in this special sample of children. This supports the view that, while common, an overlap between these aspects of psychopathology is not inevitable and so provides evidence for the dissociation of these two concepts. In terms of classification, we argue for a diagnostic scheme where psychopathy can be diagnosed independently of conduct disorder.

BACKGROUND India has a large proportion of child and adolescent population. Psychiatric disorders are common among children and adolescents, but they are often underdiagnosed. Family environment influences psychopathology in young children. Identification of risk factors for child psychiatric disorders can lead to early identification of children at risk and facilitation of preventive interventions. METHODS The study was conducted among 103 children attending the Child Guidance Clinic (CGC) in a tertiary care institute in Kerala. A specially prepared proforma was used to obtain the sociodemographic profile and clinical variables. Global Family Environment Scale was used to assess the quality of family environment. ICD 10 classification of mental and behavioural disorders was used for making diagnosis, and Ravens Coloured Progressive Matrices was used for assessing intelligence. RESULTS Emotional disorders were seen more commonly in girls, and in older age group. Children with behavioural disorders were below average in academics and the difference between the groups was statistically significant. No statistically significant difference was found between the groups in socioeconomic status, locality, family type, family history of psychiatric illness, and in family environment. CONCLUSIONS Though there was no statistically significant difference, family history of psychiatric illness and poor and moderately unsatisfactory family environment was observed in a large proportion of children. This finding may have implication in management of childhood psychiatric disorders. KEYWORDS Family Environment, Children, Emotional Disorders, Behavioural Disorders

In recent years, the evidence regarding Internet Gaming Disorder (IGD) suggests that some personality traits are important risk factors for developing this problem. The heterogeneity involved in problematic online gaming and differences found in the literature regarding the comorbid psychopathology associated with the problem could be explained through different types of gamers. Clustering analysis can allow organization of a collection of personality traits into clusters based on similarity. The objectives of this study were: (1) to obtain an empirical classification of IGD patients according to personality variables and (2) to describe the resultant groups in terms of clinical and sociodemographic variables. The sample included 66 IGD adolescent patients who were consecutive referrals at a mental health center in Barcelona, Spain. A Gaussian mixture model cluster analysis was used in order to classify the subjects based on their personality. Two clusters based on personality traits were detected: type I “higher comorbid symptoms” (n = 24), and type II “lower comorbid symptoms” (n = 42). The type I included higher scores in introversive, inhibited, doleful, unruly, forceful, oppositional, self-demeaning and borderline tendency traits, and lower scores in histrionic, egotistic and conforming traits. The type I obtained higher scores on all the Symptom Check List-90 items-Revised, all the State-Trait Anxiety Index scales, and on the DSM-5 IGD criteria. Differences in personality can be useful in determining clusters with different types of dysfunctionality.

Übergewicht und Adipositas zeigen bei Kindern und Jugendlichen eine hohe Prävalenz und Persistenz. Entsprechende Therapien sind kaum individualisiert und zeigen nur moderate Erfolge. Die Psychopathologie bleibt zumeist unberücksichtigt. Die vorliegende Studie hat die Psychopathologie von Jugendlichen mit Übergewicht und Adipositas (N = 201, Alter 12 – 17 Jahre) vor einer Gewichtsreduktionsbehandlung erhoben und Alters- sowie Geschlechtseffekte untersucht. Mittels Fragebögen wurden selbstberichtet die allgemeine Symptombelastung, Essstörungs- und allgemeine Psychopathologie, gewichtsbezogene Selbststigmatisierung und die körperliche und psychische Lebensqualität erhoben. Mädchen zeigten hypothesenkonform ein höheres Maß an gewichtsbezogener Selbststigmatisierung und eine stärkere Essstörungspsychopathologie als Jungen. Ältere Jugendliche berichteten eine geringere Lebensqualität als jüngere. Vergleiche zu Referenzgruppen aus Bevölkerungs- und Normierungsstichproben zeigten auffälligere Werte bei Jugendlichen mit Übergewicht und Adipositas für alle untersuchten Parameter. Eine auffällige Psychopathologie ist demzufolge ein wichtiges Korrelat bei Jugendlichen mit hohem Gewichtsstatus und ein potenzieller Einflussfaktor auf den Erfolg einer Gewichtsreduktionsbehandlung. Zukünftige Studien sollten die Psychopathologie bei Übergewicht und Adipositas weiter differenzieren und therapeutische Ressourcen evaluieren.
Overweight and obesity in children and adolescents are highly prevalent and persistent. Current weight loss treatments are rarely individualized and show only small to moderate efficacy. Only rarely, psychopathological parameters are considered. The present study evaluated the psychopathology of adolescents with overweight and obesity (N = 201, ages 12 – 17 years) prior to obesity treatment. The data were analyzed for age and sex effects. Self-report questionnaires assessed general symptom burden, eating disorder and general psychopathology, weight-related self-stigmatization, and physical and mental quality of life. Girls showed higher rates of weight-related self-stigmatization and higher disordered eating behavior compared to boys. Older adolescents reported a lower quality of life compared to younger adolescents. In normative comparisons with population-based samples and norms, adolescents with overweight and obesity showed significantly adverse outcomes in all parameters. Thus, this study identified psychopathology as an important factor in adolescents with high weight status that may affect obesity treatment. Future studies should examine psychopathology more differentially and determine therapeutic resources in adolescent overweight and obesity.

The objectives of the community-based Early Developmental Stages of Psychopathology (EDSP) Study are described along with a detailed account of the overall design, special design features, sample characteristics and instruments used. The EDSP employed a prospective-longitudinal design to study substance use and other mental disorders in a representative population sample of 3,021 subjects aged 14–24 years (birth cohorts 1970–1981) at ‘baseline’ – the outset of the study. Two follow-up investigations were conducted after the baseline investigation covering an overall period of 3–4 years. Special design features are the linkage with a family supplement (EDSP-FS) as well as neurobiological laboratory studies of high-risk subjects.

Parental psychopathology and unfavorable family environment are established risk factors for onset of offspring social phobia (SP), but their associations with the further course, e.g., persistence of the disorder, remain understudied. A community cohort of 1395 adolescents and their parents was followed-up over almost 10 years using the DIA-X/M-CIDI. Parental diagnostic interviews were supplemented by family history data. Parental rearing was retrospectively assessed by the Questionnaire of Recalled Parental Rearing Behavior in offspring, and family functioning by the Family Assessment Device in parents. Persistence measures (proportion of years affected since onset) were derived from diagnostic interviews, using age of onset, age of recency, and course information. Lack of emotional warmth and dysfunctional family functioning characteristics were associated with higher SP persistence, particularly in interaction with parental psychopathology. Predictors for SP persistence differ from those predicting SP onset. Unfavorable family environment alone and in interaction with parental disorders predict higher SP persistence.

Background. There are inconclusive findings regarding whether danger and loss events differentially predict the onset of anxiety and depression. Method. A community sample of adolescents and young adults (n=2304, age 14–24 years at baseline) was prospectively followed up in up to four assessments over 10 years. Incident anxiety and depressive disorders were assessed at each wave using the DSM-IV/M-CIDI. Life events (including danger, loss and respectively mixed events) were assessed at baseline using the Munich Event List (MEL). Logistic regressions were used to reveal associations between event types at baseline and incident disorders at follow-up. Results. Loss events merely predicted incident ‘pure’ depression [odds ratio (OR) 2.4 per standard deviation, 95% confidence interval (CI) 1.5–3.9, p<0.001] whereas danger events predicted incident ‘pure’ anxiety (OR 2.3, 95% CI 1.1–4.6, p=0.023) and ‘pure’ depression (OR 2.5, 95% CI 1.7–3.5, p<0.001). Mixed events predicted incident ‘pure’ anxiety (OR 2.9, 95% CI 1.5–5.7, p=0.002), ‘pure’ depression (OR 2.4, 95% CI 1.6–3.4, p<0.001) and their co-morbidity (OR 3.6, 95% CI 1.8–7.0, p<0.001). Conclusions. Our results provide further evidence for differential effects of danger, loss and respectively mixed events on incident anxiety, depression and their co-morbidity. Since most loss events referred to death/separation from significant others, particularly interpersonal loss appears to be highly specific in predicting depression.

Background. To examine the role of parental psychopathology and family environment for the risk of social anxiety disorder (SAD) in offspring from childhood to early adulthood, covering an observational period of 10 years. Method. A community sample of 1,395 adolescents (aged 14 to 17 years at baseline) was prospectively followed-up over the core high risk period for SAD onset. DSM-IV offspring and parental psychopathology was assessed using the Munich-Composite International Diagnostic Interview; direct diagnostic interviews in parents were supplemented by family history reports from offspring. Parental rearing was assessed by the Questionnaire of Recalled Rearing Behavior in offspring, family functioning by the McMaster Family Assessment Device in parents. Results. Parental SAD was associated with the offspring’s risk to develop SAD (OR = 3.3, 95%CI: 1.4-8.0). Additionally, other parental anxiety disorders (OR = 2.9, 95%CI: 1.4-6.1), depression (OR = 2.6, 95%CI: 1.2-5.4) and alcohol use disorders (OR = 2.8, 95%CI: 1.3-6.1) were associated with offspring SAD. Offspring’s reports of parental overprotection, rejection and lack of emotional warmth, but not parental reports of family functioning were associated with offspring SAD. Analyses of interaction of parental psychopathology and parental rearing indicated combined effects on the risk for offspring SAD. Conclusions. These findings extend previous results in showing that both parental psychopathology and parental rearing are consistently associated with the risk for offspring SAD. As independent and interactive effects of parental psychopathology and parental rearing may have already manifested in early adolescence, these factors appear crucial and promising for targeted prevention programs.

Despite potentially severe medical consequences of pica and rumination disorder (RD), little is known about their prevalence and association with other psychopathology in childhood. As a part of a larger population-based study, 804 youths aged 7–14 years and their parents were asked about their experience of pica and RD behaviors, and associated eating, feeding and general psychopathology. A total of 12.31% and 11.49% of youth reported having engaged in pica or RD behaviors at least once. Recurring pica or RD behaviors had been experienced by 4.98% and 1.49% of the participants. The behaviors showed a significant, but small correlation with one another (r = .28, p < .01). Correlations with symptoms of avoidant/restrictive food intake disorder (ARFID) were significant, but small (pica: r = .18, RD: r = .27, both p < .01). Prevalence rates of recurring pica behavior were significantly increased if recurring RD was present (58.33%), and also greater vice versa (17.50%). The prevalence rates for recurrent pica and RD behaviors were also increased in the presence of an ARFID diagnosis (both behaviors 12.0%). However, correlations with restraint, eating, weight, and shape concern were nonsignificant (all p > .05). In addition, RD behavior was positively correlated with emotional and conduct problems (r = .15 and .22, both p < .01) and both behaviors were negatively correlated with prosocial behavior (r = −.10 and −.09, both p < .05). Our findings underscore the clinical significance of pica and RD behaviors. More research is warranted on both disorders, their association and their relation with ARFID, in order to reach a further understanding of their presentation and to ascertain diagnostic validity.

Aims. To prospectively examine whether negative life events (NLE) and low perceived coping efficacy (CE) increase the risk for the onset of various forms of psychopathology and low CE mediates the associations between NLE and incident mental disorders. Methods. A representative community sample of adolescents and young adults (N = 3017, aged 14–24 at baseline) was prospectively followed up in up to three assessment waves over 10 years. Anxiety, depressive and substance use disorders were assessed at each wave using the DSM-IV/M-CIDI. NLE and CE were assessed at baseline with the Munich Event List and the Scale for Self-Control and Coping Skills. Associations (odds ratios, OR) of NLE and CE at baseline with incident mental disorders at follow-up were estimated using logistic regressions adjusted for sex and age. Results. NLE at baseline predicted the onset of any disorder, any anxiety disorder, panic disorder, agoraphobia, generalised anxiety disorder, any depression, major depressive episodes, dysthymia, any substance use disorder, nicotine dependence and abuse/dependence of illicit drugs at follow-up (OR 1.02–1.09 per one NLE more). When adjusting for any other lifetime disorder prior to baseline, merely the associations of NLE with any anxiety disorder, any depression, major depressive episodes, dysthymia and any substance use disorder remained significant (OR 1.02–1.07). Low CE at baseline predicted the onset of any disorder, any anxiety disorder, agoraphobia, generalised anxiety disorder, any depression, major depressive episodes, dysthymia, any substance use disorder, alcohol abuse/dependence, nicotine dependence and abuse/dependence of illicit drugs at follow-up (OR 1.16–1.72 per standard deviation). When adjusting for any other lifetime disorder prior to baseline, only the associations of low CE with any depression, major depressive episodes, dysthymia, any substance use disorder, alcohol abuse/dependence, nicotine dependence and abuse/dependence of illicit drugs remained significant (OR 1.15–1.64). Low CE explained 9.46, 13.39, 12.65 and 17.31% of the associations between NLE and any disorder, any depression, major depressive episodes and dysthymia, respectively. When adjusting for any other lifetime disorder prior to baseline, the reductions in associations for any depression (9.77%) and major depressive episodes (9.40%) remained significant, while the reduction in association for dysthymia was attenuated to non-significance ( p-value > 0.05). Conclusions. Our findings suggest that NLE and low perceived CE elevate the risk for various incident mental disorders and that low CE partially mediates the association between NLE and incident depression. Subjects with NLE might thus profit from targeted early interventions strengthening CE to prevent the onset of depression.

Background: Effective interventions for maltreated children are impeded by gaps in our knowledge of the etiopathogenic mechanisms leading from maltreatment to mental disorders. Although some studies have already identified individual risk factors, there is a lack of large-scale multilevel research on how psychosocial, neurobiological, and genetic factors act in concert to modulate risk of internalizing psychopathology in childhood following maltreatment. To help close this gap, we aim to delineate gender-specific pathways from maltreatment to psychological disorder/resilience. To this end, we examine the interplay of specific maltreatment characteristics and psychological, endocrine, metabolomic, and (epi-)genomic stress response patterns as well as cognitive-emotional/social processes as determinants of developmental outcome. Specifically, we will explore endocrine, metabolomic, and epigenetic mechanisms leading from maltreatment to a higher risk of depression and anxiety disorders.

Background. Previous research suggests that individuals experiencing DSM-IV panic attacks (PA) are at increased risk for various forms of psychopathology, including anxiety, depressive and substance use disorders. However, little is known regarding whether the sole occurrence of fearful spells (FS-only; distressing spells of anxiety with less than four panic symptoms and/or lacking crescendo in symptom onset) similarly elevates the risk for subsequent psychopathology and could therefore be promising to identify high-risk groups for targeted preventive interventions. Thus, the current dissertation thesis aims to examine (a) whether FS-only predict incident mental disorders in addition to full-blown PA and whether their associations with subsequent psychopathology differ from those obtained for PA, (b) whether FS-only, PA, and panic disorder (PD) share similar etiologies, (c) which characteristics of initial FS/PA and other risk factors predict a progression to more severe panic pathology and other mental disorders, and (d) whether help-seeking/potential treatment in individuals with panic alters the risk for subsequent psychopathology. Methods. A representative community sample of adolescents and young adults (N=3021, aged 14-24 at baseline) was prospectively followed up in up to three assessment waves over a time period of up to 10 years. FS-only, PA, PD, and other mental disorders were assessed at each assessment wave using the DSM-IV-M-CIDI. Additional modules/questionnaires were used to assess characteristics of initial FS/PA (T1/T2), potential risk factors, and help-seeking/potential treatment. Logistic regressions were applied to test associations (Odds Ratios, OR) of FS-only and PA at baseline with incident mental disorders at follow-up as well as respective interactive effects with help-seeking at baseline. Associations (Hazard Ratios, HR) of putative risk factors with the onset of panic pathology (FS-only, PA, and PD) or the onset of subsequent anxiety/depressive vs. substance use disorders in those with panic pathology (aggregated data across assessment waves) were estimated with Cox regressions. Multinomial logistic regressions were used to test associations of initial FS/PA characteristics (aggregated from T1 and T2) with PA and PD (lifetime incidences aggregated across assessment waves). Results. FS-only at baseline predicted incident anxiety and depressive disorders at follow-up (OR 1.59-4.36), while PA at baseline predicted incident anxiety, depressive, and substance use disorders at follow-up (OR 2.08-8.75; reference group: No FS/PA). Merely any anxiety disorder (OR=3.26) and alcohol abuse/dependence (OR=2.26) were significantly more strongly associated with PA than with FS-only. Female sex, parental anxiety disorders, parental depressive disorders, behavioral inhibition, harm avoidance, lower coping efficacy, and parental rejection predicted FS-only, PA, and PD (HR 1.2-3.0), whereas the associations with other risk factors partially differed for FS-only, PA, and PD and tended to be more pronounced for PA and PD than for FS-only. Alcohol consumption, use of drugs/medication, and physical illness as perceived reasons for the initial FS/PA were associated with the occurrence of full-blown PA (without PD, OR 2.46-5.44), while feelings of anxiety/depression and having always been anxious/nervous as perceived reasons for the initial FS/PA, appraising the initial FS/PA as terrible and long-term irritating/burdensome, subsequent feelings of depression, avoidance of situations/places, and consumption of medication, alcohol, or drugs were associated with the development of PD (OR 2.64-4.15). A longer duration until “feeling okay again” was associated with both PA and PD (OR 1.29-1.63 per category). Moreover, partially different risk constellations in subjects with panic pathology (FS/PA/PD) predicted the onset of subsequent anxiety/depressive vs. substance use disorders. Panic pathology (FS/PA) and help-seeking/potential treatment at baseline interacted on predicting incident PD (OR=0.09) and depression (OR=0.22) at follow-up in a way that panic pathology only predicted these disorders in individuals not seeking help at baseline. Conclusions. Findings suggest that individuals with FS-only are at similar risk of developing subsequent psychopathology compared to individuals with full-blown PA. Specific initial FS/PA characteristics and additional risk factors may be used to identify sub-groups of individuals with panic pathology, which are at particular risk of progressing to more severe panic pathology or other mental disorders and might therefore profit from supplemental outcome-related preventive interventions in addition to panic-specific treatment. Future research may replicate the current findings and test the efficacy of targeted preventive interventions in panickers at elevated risk for PD and other forms of psychopathology.:CONTENT 0 Synopsis 10 1 Introduction 13 1.1 Current challenges in clinical psychology 13 1.2 Psychological models of mental disorders 13 1.3 Diagnostic approaches to psychopathology 15 1.4 Methodological issues 16 1.5 Preventive and early treatment interventions 17 2 Panic pathology 18 2.1 Definitions 18 2.2 Epidemiology 19 2.3 Etiology 20 2.4 Physiological, neurobiological, and genetic findings 21 2.5 Unresolved issues 22 3 Aims 24 4 Methods 26 5 Study I: Associations of fearful spells and panic attacks with incident anxiety, depressive, and substance use disorders: A 10-year prospective-longitudinal community study of adolescents and young adults 27 5.1 Abstract 27 5.2 Introduction 27 5.3 Materials and methods 28 5.4 Results 30 5.5 Discussion 35 6 Study II: Characteristics of initial fearful spells and their associations with DSM-IV panic attacks and panic disorder in adolescents and young adults from the community 37 6.1 Abstract 37 6.2 Introduction 37 6.3 Materials and methods 38 6.4 Results 41 6.5 Discussion 43 7 Study III: Risk factors for fearful spells and panic: A 10-year prospective-longitudinal study among adolescents and young adults 47 7.1 Abstract 47 7.2 Introduction 47 7.3 Materials and methods 49 7.4 Results 52 7.5 Discussion 60 8 Study IV: Does help-seeking alter the risk for incident psychopathology in adolescents and young adults with and without fearful spells or panic attacks?

Theoretischer Hintergrund. Auf Grundlage früherer Forschungsbefunde ist anzunehmen, dass Personen mit DSM-IV-Panikattacken (PA) ein erhöhtes Risiko für zahlreiche psychische Störungen, einschließlich Angst-, depressiver und Substanzstörungen, aufweisen. Unklar ist jedoch, ob das alleinige Auftreten von Fearful Spells (FS-only, Angstanfälle mit weniger als vier Paniksymptomen und/oder fehlendem Crescendo in der Symptomentwicklung) das Risiko für Psychopathologie in ähnlicher Weise erhöht und hilfreich sein könnte, um Hochrisikogruppen für Präventivinterventionen zu identifizieren. Innerhalb der vorliegenden Dissertation wird daher untersucht, (a) ob FS-only zusätzlich zu PA inzidente psychische Störungen vorhersagen und ob sich Unterschiede in den Assoziationen von FS-only vs. PA mit nachfolgender Psychopathologie ergeben, (b) ob FS-only, PA und Panikstörung (PS) ähnliche Ätiologien teilen, (c) welche Merkmale initialer FS/PA und welche anderen Risikofaktoren die Entwicklung schwerer Panikpathologie und weiterer psychischer Störungen vorhersagen und (d) ob Hilfesuchverhalten/potenzielle Behandlung bei Personen mit Panik das Risiko für nachfolgende Psychopathologie verändert. Methodik. Eine repräsentative Bevölkerungsstichprobe Jugendlicher und junger Erwachsener (N=3021, 14-24 Jahre zur Baseline-Erhebung) wurde in bis zu drei Erhebungswellen über einen Zeitraum von bis zu 10 Jahren untersucht. FS-only, PA, PS und andere psychische Störungen wurden zu jeder Erhebungswelle mithilfe des DSM-IV-M-CIDI erfasst. Merkmale initialer FS/PA (T1/T2), mögliche Risikofaktoren sowie Hilfesuchverhalten/potenzielle Behandlung wurden mit weiteren Modulen und Fragebögen erhoben. Mithilfe logistischer Regressionen wurden Assoziationen (Odds Ratios, OR) von FS-only und PA zu Baseline mit inzidenten psychischen Störungen zum Follow-Up sowie diesbezügliche Interaktionen mit Hilfesuchverhalten zu Baseline getestet. Zusammenhänge zwischen möglichen Risikofaktoren und dem Auftreten von Panikpathologie (FS-only, PA und PS) bzw. nachfolgender Angst-/depressiver und Substanzstörungen bei Personen mit Panikpathologie (Verwendung von über die Erhebungswellen hinweg aggregierter Daten) wurden mithilfe von Cox-Regressionen geschätzt. Multinomiale logistische Regressionen wurden genutzt, um Assoziationen von Merkmalen initialer FS/PA (aggregiert über T1 und T2) mit PA und PS (über die Erhebungswellen hinweg aggregierte Lebenszeitinzidenzen) zu erfassen. Ergebnisse. FS-only zu Baseline sagten inzidente Angst- und depressive Störungen zum Follow-Up vorher (OR 1.59-4.36), wohingegen PA zu Baseline inzidente Angst-, depressive und Substanzstörungen zum Follow-Up vorhersagten (OR 2.08-8.75; Referenzkategorie: Keine FS/PA). Lediglich irgendeine Angststörung (OR=3.26) und Alkoholmissbrauch/-abhängigkeit (OR=2.26) waren signifikant stärker mit PA als mit FS-only assoziiert. Weibliches Geschlecht, elterliche Angst- und depressive Störungen, Verhaltenshemmung, Schadensvermeidung, geringere Coping-Erwartung und elterliche Zurückweisung sagten FS-only, PA und PS vorher (HR 1.2-3.0), während sich teils unterschiedliche Assoziationen anderer Risikofaktoren mit FS-only, PA und PS ergaben, die tendenziell stärker für PA und PS als für FS-only waren. Alkoholkonsum, Drogen-/Medikamentengebrauch und körperliche Erkrankungen als wahrgenommene Gründe für die initiale FS/PA waren mit dem Auftreten vollständiger PA assoziiert (ohne PS; OR 2.46-5.44), während Gefühle von Angst/Depression und die Einschätzung schon immer ängstlich/nervös gewesen zu sein als wahrgenommene Gründe für die initiale FS/PA, die Bewertung der initialen FS/PA als schrecklich und langfristig verunsichernd/belastend, nachfolgende Gefühle von Niedergeschlagenheit, Vermeidung von Situationen/Orten und Konsum von Medikamenten, Alkohol oder Drogen mit der Entwicklung von PS assoziiert waren (OR 2.64-4.15). Eine längere Dauer bis sich die betroffene Person wieder vollständig in Ordnung fühlte war sowohl mit PA als auch mit PS assoziiert (OR 1.29-1.63 pro Kategorie). Weiterhin sagten teils unterschiedliche Risikokonstellationen bei Personen mit Panikpathologie (FS/PA/PS) die nachfolgende Entstehung von Angst-/depressiven und Substanzstörungen vorher. Panikpathologie (FS/PA) und Hilfesuchverhalten/potenzielle Behandlung zu Baseline interagierten bei der Vorhersage von inzidenter PS (OR=0.09) und Depression (OR=0.22) zum Follow-Up; d.h. das Vorhandensein von Panikpathologie sagte diese Störungen nur bei Personen ohne, nicht aber bei Personen mit Hilfesuchverhalten zu Baseline vorher. Schlussfolgerungen. Die vorliegenden Ergebnisse implizieren, dass Personen mit FS-only im Vergleich zu Personen mit vollständigen PA ein ähnliches Risiko für die Entwicklung nachfolgender Psychopathologie aufweisen. Spezifische Merkmale initialer FS/PA und zusätzliche Risikofaktoren könnten zur Identifikation von Sub-Gruppen von Personen mit Panik genutzt werden, die sich durch ein besonderes Risiko für schwergradige Panikpathologie und andere psychische Störungen auszeichnen und demzufolge von Outcome-bezogenen Präventionen (ergänzend zu Panik-spezifischer Intervention) profitieren könnten. Zukünftige Studien sollten die vorliegenden Befunde replizieren und die Effektivität gezielter Präventivinterventionen bei Personen mit erhöhtem Risiko für PS und andere psychische Störungen testen.:CONTENT 0 Synopsis 10 1 Introduction 13 1.1 Current challenges in clinical psychology 13 1.2 Psychological models of mental disorders 13 1.3 Diagnostic approaches to psychopathology 15 1.4 Methodological issues 16 1.5 Preventive and early treatment interventions 17 2 Panic pathology 18 2.1 Definitions 18 2.2 Epidemiology 19 2.3 Etiology 20 2.4 Physiological, neurobiological, and genetic findings 21 2.5 Unresolved issues 22 3 Aims 24 4 Methods 26 5 Study I: Associations of fearful spells and panic attacks with incident anxiety, depressive, and substance use disorders: A 10-year prospective-longitudinal community study of adolescents and young adults 27 5.1 Abstract 27 5.2 Introduction 27 5.3 Materials and methods 28 5.4 Results 30 5.5 Discussion 35 6 Study II: Characteristics of initial fearful spells and their associations with DSM-IV panic attacks and panic disorder in adolescents and young adults from the community 37 6.1 Abstract 37 6.2 Introduction 37 6.3 Materials and methods 38 6.4 Results 41 6.5 Discussion 43 7 Study III: Risk factors for fearful spells and panic: A 10-year prospective-longitudinal study among adolescents and young adults 47 7.1 Abstract 47 7.2 Introduction 47 7.3 Materials and methods 49 7.4 Results 52 7.5 Discussion 60 8 Study IV: Does help-seeking alter the risk for incident psychopathology in adolescents and young adults with and without fearful spells or panic attacks?

This chapter discusses psychiatry. It outlines psychiatric history skills (principles, mental state exam, risk assessment, confidentiality, and physical ecamination), assessment of psychiatric symptoms (descriptive psychopathology, classification of disorders (ICD-10, DSM-V)), community psychiatry (community care, schizophrenia, depression, bipolar affective disorder, anxiety, OCD, and PTSD, and the withdrawal of psychotropics), emergency department psychiatry (suicide and suicidal ideation, deliberate self-harm, crisis intervention, urgent psychiatry situations, and managing violence), liaison psychiatry and organix illness (delirium and dementia), child and adolescent psychiatry (depression, psychosis, behavioural difficulties, sleep disorders, ASD, and ADHD), psychiatric subspecialties (substance and alcohol misuse, intellectual disability, personality disorders, eating disorders, psychosexual disorders, and perinatal disorders), psychological treatment and psychotherapy (cognitive therapy, behavioural therapy, dynamic psychotherapy, systemic/family therapy, counselling and supportive psychotherapy, group psychotherapy, play and art therapy), and mental health and the law (compulsory hospitalisation, consent, capacity, and the Mental Health Act).

Classification of child psychiatric conditions has advanced enormously in the last 20 years. There is a much stronger empirical basis to support current schemes, which are grounded in the many scientific disciplines that contribute to developmental psychopathology. Nonetheless there are considerable obstacles to overcome if DSM V and ICD 11 are to be major steps forward.
