My research centers on two topics:

  • Depression, Affective Disorders

    Keywords: Assessment, diagnosis, classification, cognitive behavioural therapy

    A classification of instruments for the assessment of depression can be based on two major distinguishing features, namely (1) the differentiation between dimensional and categorical levels of measurement, and (2) the consideration of the influence of the applied method: questionnaire versus interview. Departing from this approach we evaluated the reliability and validity of several instruments measuring depression such as the Beck Depression Inventory, the Zung Depression Scale and the Hamilton Depression Rating Scale (e.g., Schotte et al., 1996, 1997; for a review see Schotte & Maes, 2001).

    The importance of the differentiation between dimensional and categorical levels of measurement can also be recognised within the discussion on quantitative/dimensional versus qualitative/categorical taxonomic views on depression. The Integrated Threshold Model was developed by our research group and integrates both the quantitative and the qualitative view on the classification of depressive disorders (e.g., Schotte et al., 1997; for a review see Schotte & Maes, 2001).

    Effective treatment of severe or chronic unipolar depression requires the combination of pharmacological and psychotherapeutic interventions and demands a theoretical paradigm integrating biological and psychosocial aspects of depression. Supported by recent research, the present essay proposes a biopsychosocial diathesis-stress model of depression. Its basic aim is psychoeducational: to provide therapists, patients and their environment a constructive conceptual framework to understand depressive complaints, vulnerability and stress.

  • Personality Disorders

    Keywords: Assessment, diagnosis, classification, cognitive behavioural therapy

    Our research considers methods, instruments, and strategies for assessing the personality disorders as described within the frame of the DSM-IV classification. However, we emphasize the interaction between diagnosis and treatment and recommend a two-tier diagnostic strategy for the diagnostic assessment of the personality disorders. Tier one results in a DSM-IV Axis II categorical diagnosis, whereas tier two refers to a dimensional, or functional approach, based on a biopsychosocial theoretical model and offering therapeutic prospects.

    The application of this diagnostic strategy in the clinical context involves feedback to the patient, in which the descriptive evaluation is integrated with etiologic and pathogenic elements using an idiographic approach. This therapeutically oriented diagnostic strategy is exemplified by the use of our ADP-IV (Assessment of DSM-IV Personality disorders) questionnaire. Our approach constitutes a way to fill the (large) gap between the descriptive DSM-IV diagnostics and a (psycho)therapeutically oriented diagnostic view (e.g., Schotte , De Doncker & Courjaret, 2007).

Varia / Miscellaneous

Hoofdauteur en ontwikkelaar van de Nederlandstalige ADP-IV vragenlijst, welke vertaald is in het Engels, Japans, Frans, Duits, Italiaans.

De ADP-IV is een vragenlijst voor de descriptieve diagnostiek van de DSM-IV persoonlijkheidsstoornissen, die bijzonder bruikbaar is om in het kader van een psychotherapeutische diagnostiek bij te dragen tot de ontwikkeling van een probleemsamenhang. De ADP-IV vragenlijst is wordt in het Nederlandse taalgebied als één van de belangrijkste en meest valide As II  instrumenten beschouwd (e.g., Vertommen en Maesschalk, 1997; Verheul, Van den Brink, Spinhoven et al., 2000; Arntz, van Genderen en Wijts, 2006 ).

Hoofdauteur en ontwikkelaar van de ADP-IV Internettoepassing

De ADP-IV internettoepasing werd ontwikkeld door Schotte, De Doncker en De Ruyter. Volgende methode wordt gehanteerd: De diagnosticus logt vanuit zijn werksituatie in op de ADP-IV         homepage (http://webhost.ua.ac.be/adpiv/). Geanonimiseerde gegevens over de cliënt, zijn/haar zelfbeschrijving, de klinische DSM-IV As I en As II diagnoses en de scores op de  ADP-IV items worden ingebracht.  Na inbreng worden de data door het programma verwerkt en worden dimensionele schaalscores, categoriale ADP-IV diagnoses en therapeutisch relevante informatie op het scherm vertoond en op de site opgeslagen. De clinicus kan te allen tijde een Word- document downloaden (ongeveer 7 pagina's) waarin de ADP-IV informatie overzichtelijk wordt voorgesteld. Het ADP-IV verslag kan bewerkt en aangevuld worden en in een globaal diagnostisch verslag ondergebracht worden. De ADP-IV internettoepassing wordt op dit ogenblik door een tal van clinici uit diverse ambulante en residentiële psychiatrische en psychotherapeutische settingen in Vlaanderen en Nederland regelmatig gebruikt. Deze dienstverlening is gratis en vindt plaats binnen het kader van een onderzoeksovereenkomst.
