Danger and loss events and the incidence of anxiety and depressive disorders: a prospective-longitudinal community study of adolescents and young adultsAsselmann, E., Wittchen, H.-U., Lieb, R., Höfler, M., Beesdo-Baum, K. 11 June 2020 (has links)
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.

Standardized Assessment of Psychopathology by Relatives of Mentally Disordered Patients: Preliminary Results of Using the Positive and Negative Syndrome Scale to Compare Schizophrenic and Affective DisordersNitsche, Ines, Kallert, Thomas W. January 2007 (has links)
Background: For optimizing the validity of diagnoses of mental disorders, several sources of information should be used to assess psychopathological symptoms. Among these are relatives of patients with mental illness. The very low number of empirical studies examining the assessment of psychopathology by relatives of adult, nondemented mentally ill patients stands in significant contrast to the clinical importance of this source of information, however. Sampling and Methods: Using the Positive and Negative Syndrome Scale (PANSS), researchers asked 163 relatives of patients with the main clinical ICD-10 diagnosis of schizophrenic, recurrent depressive or bipolar disorders to rate the current symptoms of the patients at the time of outpatient community-oriented treatment. Results: On average, severity of symptoms was rated as absent or minimal, although anxiety, depression and passive/apathetic social as well as emotional withdrawal, motor retardation, poor attention, and disturbance of volition were clearly rated above the PANSS mean total score for all patients. A six-factor structure identified by factor analysis better illustrates the significant differences in the assessments of the three main diagnostic groups than the three established PANSS scales. With the exception of ‘problematic social behavior’, differences among the diagnostic groups appeared in all factors and were particularly pronounced for ‘delusional beliefs’ and ‘motor impairments’. Conclusions: The results of this study showed that the use of standardized instruments such as PANSS for the assessment of psychopathology by relatives is not only practical, but produces adequately reliable results. The use of PANSS for this purpose, however, requires interviewing of relatives by trained experts able to explain technical terms. Because this study did not sufficiently explore the validity of this approach, further research on this specific issue is urgently needed and should, for example, assess the concordance of ratings between professionals and relatives as well as correlation with suitable external criteria. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

Associations of familial risk factors with social fears and social phobia: evidence for the continuum hypothesis in social anxiety disorder?Knappe, Susanne, Beesdo, Katja, Fehm, Lydia, Lieb, Roselind, Wittchen, Hans-Ulrich January 2009 (has links)
We examined parental psychopathology and family environment in subthreshold and DSM-IV threshold conditions of social anxiety disorder (SAD) in a representative cohort sample of 1,395 adolescents. Offspring and parental psychopathology was assessed using the DIAX/ M-CIDI; recalled parental rearing and family functioning via questionnaire. Diagnostic interviews in parents were supplemented by family history reports from offspring. The cumulative lifetime incidence was 23.07% for symptomatic SAD, and 18.38 and 7.41% for subthreshold and threshold SAD, respectively. The specific parent-tooffspring association for SAD occurred for threshold SAD only. For subthreshold and threshold SAD similar associations were found with other parental anxiety disorders, depression and substance use disorders. Parental rearing behaviour, but not family functioning, was associated with offspring threshold SAD, and although less strong and less consistent, also with subthreshold SAD. Results suggest a continued graded relationship between familial risk factors and offspring SAD. Parental psychopathology and negative parental styles may be used defining high-risk groups to assign individuals with already subthreshold conditions of SAD to early intervention programs.

Do parental psychopathology and unfavorable family environment predict the persistence of social phobia?Knappe, Susanne, Beesdo, Katja, Fehm, Lydia, Höfler, Michael, Lieb, Roselind, Wittchen, Hans-Ulrich January 2009 (has links)
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.

Investigation of the relation between substance use and cognitive performance and its mediating effect on psychopathology symptomsMorin, Jean-François G. 01 1900 (has links)
Le projet de thèse porte sur la consommation de substances psychoactives chez les adolescents et le lien séquentiel entre la consommation de drogues, la performance cognitive, et la santé mentale des jeunes. Les objectifs de la thèse sont : 1) de tester la relation entre la prise de cannabis, ou d’alcool, et la performance cognitive, et d’en observer la séquence, 2) de vérifier si la relation entre la consommation et la performance cognitive permet, en partie, de comprendre l’apparition de symptômes de psychopathologie chez les jeunes, et 3) de définir les pratiques les mieux fondées empiriquement pour prévenir la consommation de substances chez les adolescents.
Le premier chapitre de la thèse évalue la relation et la séquence entre les habitudes de consommation d’environ 4000 jeunes de la région métropolitaine de Montréal (Qc, Canada) et la trajectoire de leur développement cognitif sur une période de quatre ans. Dans un deuxième chapitre, la thèse évalue comment la relation entre la consommation et la performance cognitive de ces mêmes jeunes peut expliquer, sur une période de cinq ans, une partie de la relation observée entre la consommation et l’apparition de symptômes de psychopathologie. Dans un dernier chapitre, la thèse fait la revue des données portant sur trois types d’interventions préventives afin d’identifier comment la recherche empirique peut bonifier les efforts de prévention de la toxicomanie chez les adolescents.
Les données ont été extraites d’une cohorte d’adolescents issus de la population générale, suivis longitudinalement, dans le cadre de l’étude Co-Venture (n = 3826, âgés de 12 ans à l’admission dans l’étude, suivis annuellement pendant 5 ans).
Les résultats ont démontré que, bien que certains facteurs semblent prédisposer un sous-groupe de jeunes à une consommation hâtive ainsi que des difficultés neuropsychologiques, la consommation de drogues, notamment de cannabis, semble liée, de façon à la fois ponctuelle et durable, à un délai du développement cognitif, plus particulièrement des fonctions exécutives. Cette association avec le cannabis semble, en faible partie, jouer un rôle médiateur dans la relation qui unit cette consommation et l’émergence de symptômes de psychopathologie chez les adolescents. Toutefois, des facteurs prédisposants semblent contribuer à l’association entre ces trois variables. Bien que la recherche identifie que plusieurs programmes de prévention peuvent être efficaces, la majorité d’entre eux présentent des effets modestes et ponctuels. Les programmes les plus probants semblent s’inscrire dans le registre des approches de prévention ciblées.
Pour bonifier nos méthodes de prévention de la toxicomanie chez les adolescents, nous pourrions tenir compte de certains facteurs prédisposants et les utiliser comme cible d’intervention; par exemple, le fonctionnement cognitif basal pourrait constituer une piste intéressante. De plus, le tempérament ou la personnalité semblent mieux établis pour prévenir la consommation de façon durable et pour aborder les enjeux cognitifs et psychologiques associés à la consommation abusive de substances.
Mots-clés : Alcool, cannabis, adolescence, fonctions cognitives, symptômes de psychopathologie, devis longitudinaux, médiation, prévention / This thesis project addresses adolescents’ substance misuse and the sequential link between drug use, cognitive performance, and mental health outcomes in youth. The objectives of this thesis are: 1) to test the relation and sequence between cannabis or alcohol use and cognitive outcomes, 2) to verify if the relation between substance use and cognitive outcomes could help understand, in part, why young substance users report psychopathology symptoms, and 3) to review evidence-based interventions to prevent adolescent substance misuse and to assess what contribution could stem from the collected empirical data.
The first chapter of this thesis assesses the relation and sequence between substance use behaviour of nearly 4000 youth from the Montreal metropolitan area (QC, Canada) and their cognitive development over four years. In a second chapter, this thesis analyzes how the association between substance use and cognitive outcomes could partially explain, over five years, the link observed between substance use and the appearance of psychopathology symptoms. In a final chapter, this thesis reviews data surrounding three types of preventative interventions to identify how empirical research could improve addiction prevention strategies.
The data was extracted from a group of adolescents issued from the general population followed longitudinally in the scope of the Co-Venture study (n = 3826, from 12 years of age upon admission to the study, followed up annually for a period of five years).
The results demonstrated that, although certain factors seem to predispose a sub-group of young people to early consumption and neuropsychological difficulties, drug consumption, especially cannabis consumption, seem to reliably predict a delay in the development of cognitive faculties, particularly the executive functions of the brain. This association with cannabis appears, to a small extent, to partially mediate the link already observed between said consumption and the emergence of psychopathology symptoms in adolescents. Still, predisposing factors seem to contribute to the association between these three variables. Although research would appear to show that several prevention strategies could be effective, most of them present modest and punctual results. The best-substantiated programs appeared to be those that adhered to a targeted prevention approach.
To improve our methods of substance use prevention, one could take predisposing factors into account and use them to inform specialized intervention. Baseline cognitive functioning could constitute a particularly promising avenue. All the same, certain predisposing factors such as temperament or personality seem better equipped to prevent early-onset substance misuse and to address the psychological and cognitive issues associated with adolescent substance intake.
To improve addiction prevention methods in adolescents, one could factor into account predisposing factors and use them to inform specialized intervention; for example, baseline cognitive functioning could constitute a promising avenue. In addition, temperament or personality traits seem better established to prevent early-onset substance use and to address the psychological and cognitive issues associated with adolescents’ substance misuse.

Intoxications médicamenteuses volontaires répétées : une conduite addictive plutôt que suicidaire. Phénotypage clinique et modélisation comportementale par une approche dimensionnelle / Repeated self-poisoning : an addictive rather than a suicidal behavior. Clinical phenotyping and behavioral modeling using a dimensional approachPennel, Lucie 03 November 2016 (has links)
Les intoxications médicamenteuses volontaires répétées (IMVr) constituent un problème de santé publique croissant, mais sous-évalué et traité comme une conduite suicidaire, alors qu’elles appartiendraient au registre des addictions. Notre travail abonde dans ce sens en montrant que les suicides alcoolisés se font principalement par IMV et correspondent au deliberate self-harm syndrom ; les suicidants récidivants se distinguent par un névrosisme et un attachement anxieux typiques des addictions ; les IMVr même suicidaires témoignent d’une relation addictive aux médicaments ; le facteur le plus prédictif d’IMV serait de l’avoir envisagée. Conceptualisé de façon translationnelle et argumenté par une approche pharmacologique, nous proposons un modèle dimensionnel des conduites suicidaires, intégré au continuum des addictions, confirmant l’hypothèse initiale et l’intérêt d’un raisonnement transnosographique diagnostique et thérapeutique dans le champ des pathologies mentales. / Repeated Self-poisoning (RSP) constitute an under evaluated but growing public health problem, treated as a suicidal rather than an addictive behavior. Our work brings arguments by showing that suicides involving alcohol are mainly by self-poisoning and correspond to deliberate self-harm syndrome; repeat suicide attempters are identified by a neuroticism and anxious attachment typically found in addicts; even suicidal RSP shows addictive behavior involving medicines; the best predictor of self-poisoning is having thought about it. Conceptualized through a translational approach and supported by pharmacological arguments, we propose a multidimensional model of suicidal behaviors, that could integrate the continuum of addictive behaviors. This confirms the initial hypothesis and the viability of a transnosographic concept for diagnosis and treatment of mental illnesses.

The Role of Parental Psychopathology and Family Environment for Social Anxiety Disorder in the First Three Decades of Life: parental psychopathology and family environment in social anxiety disorderKnappe, Susanne, Lieb, Roselind, Beesdo, Katja, Fehm, Lydia, Low, Nancy Chooi Ping, Gloster, Andrew T., Wittchen, Hans-Ulrich January 2009 (has links)
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.

Adaptation dans un contexte scolaire : évaluation et évolution du risque au cours de l'enfanceCouture, Germain. 17 February 2021 (has links)
Le but de cette thèse est l'étude de variables susceptibles d'orienter le cours du développement d'une situation de risque initiale vers la manifestation ultérieure de problèmes d'adaptation scolaire sous l'angle du rendement scolaire et des problèmes de comportement. L'échantillon étudié est composé de 41 enfants à risque et de 22 enfants non à risque, recrutés vers l'âge de 1 an. Les mesures d'adaptation scolaire ont été effectuées vers l'âge de 11 ans. Les résultats indiquent que l'incidence de problèmes de rendement scolaire et de comportement est plus élevée chez les enfants exposés au risque pour lesquels la persistance de l'exposition au cours du développement est la plus intense. Le rôle de l'encadrement parental comme mécanisme de protection, permettant á des enfants à risque de connaître malgré tout une bonne adaptation scolaire, n'a pu être démontré au sein de l'échantillon étudié.

La violence psychologique entre les parents et leurs adolescents et l'adaptation des jeunesMelançon, Claudiane 16 April 2018 (has links)
Une proportion importante d'adolescents subissent la violence psychologique de leurs parents et les effets potentiels peuvent s'avérer particulièrement néfastes quant à la santé mentale de ces jeunes. La présente thèse vise à étudier le lien entre la violence psychologique et l'adaptation des jeunes. Dans le premier chapitre, la violence psychologique du père et de la mère sont examinées séparément en tant que facteurs de risque des problèmes de comportement intériorisés et extériorisés des adolescents. La violence familiale vécue dans l'enfance, la violence extrafamiliale vécue en concomitance et la structure familiale sont prises en considération. Le second chapitre se penche sur le rôle des stratégies d'adaptation (approche et évitement) en tant que facteurs médiateurs expliquant le lien entre la violence psychologique des parents et les problèmes de comportement des adolescents. Ce chapitre étudie également le rôle protecteur du soutien social. Le quatrième chapitre explore la réciprocité de la violence psychologique entre les parents et leurs adolescents. L'Inventaire des Conduites Adolescentes Psychologiquement Violentes (ICAPV) a d'abord été conçu pour cette fin et il est présenté au chapitre 3. Un groupe de 278 adolescents (âge moyen : 14.2 ans) a été recruté dans trois écoles secondaires de niveau socioéconomique allant de faible à élevé situées dans la région de Québec. Les participants étaient en première, deuxième et troisième secondaire et ont rempli un questionnaire auto-administré. La violence psychologique des deux parents est associée aux problèmes de comportement des adolescents au-delà de la structure familiale et des autres types de violence considérés dans l'étude. Elle est également modérément associée à la violence psychologique de l'adolescent. Chez les filles, l'évitement est associé à une augmentation des problèmes intériorisés et extériorisés, alors que l'approche est associée à une augmentation des problèmes extériorisés chez les garçons. Aucun rôle protecteur du soutien social n'a été trouvé. Au contraire, cette variable semble être associée à une augmentation de la force de la relation entre la violence psychologique et les problèmes de comportement extériorisés chez les garçons. Les résultats démontrent l'urgence d'agir pour aider les jeunes subissant de la violence psychologique au moyen de programmes de prévention et d'intervention efficaces.
