Differential Cognitive Treatment of Polythematic Delusions and Generalised Anxiety Disorder

640px-Panic-attackEnglish translation of a paper published in french under the title “Traitement cognitif différentiel des délires polythématiques et du trouble anxieux généralisé”, in the Journal de Thérapie Comportementale et Cognitive, 2011, vol. 21-4, pp. 121-125.

Schizophrenia is often associated with other physical and mental problems. Generalized anxiety disorder is notably one of the comorbid disorders which is often linked to schizophrenia. The association of polythematic delusions and of ideas resulting from generalized anxiety disorder complicates the exercise of the corresponding cognitive therapy, for the resulting ideas are most often inextricably intertwined. In what follows, we endeavour to propose a methodology for the differential treatment of polythematic delusions inherent to schizophrenia when combined with ideas originating from generalized anxiety disorder. We propose, with regard to the corresponding content of delusions, an analysis which allows under certain conditions, to separate the content associated with polythematic delusions and the one that relates to generalized anxiety disorder, in order to facilitate the exercise of the corresponding cognitive therapy.

Polythematic Delusions and Logico-Theoretical vs. Experimentalist Turn of Mind

George Grie-Panic-attackpaper published in the Journal for Neurocognitive Research,  Vol.  2013, 55, No. 1-2.

This article aims to contribute to cognitive therapy of polythematic delusions by proposing a preliminary step to the implementation of traditional cognitive therapy, based on the construction of alternative hypotheses to delusions and testing of the latter. This additional step resides in the construction in the patient of the necessary skills to use the general experimentalist method of knowledge acquisition. Such an approach is based on the contrast between the logico-theoretical and the experimentalist turn of mind. Some elements such as to allow any such construction in the patient are then described and analyzed.

Polythematic Delusions and Logico-Theoretical vs.  Experimentalist Turn of Mind

Classical cognitive therapy targeted at polythematic delusions associated with schizophrenia is based on the search for evidence related to delusional ideas and the construction of alternative hypotheses to the latter. This article aims to contribute to cognitive therapy for polythematic delusions by proposing a preliminary step to this classical cognitive therapy. Such a step aims to strengthen the patient’s ability to use the general approach of experimentalist type for knowledge acquisitionan approach which is based on the opposition between the theoretical-logical and the experimentalist turn of mind. Some elements such as to enable the reinforcement of such a capability in the patient are thus described and analyzed.

On the Plausibility of Psychotic Hallucinations

anonyme flamand_cauchemarA paper published in the Journal for Neurocognitive Research,  Vol. 53, No 1-2 (2011).

In this paper, we describe several factors that can contribute, from the patient’s viewpoint, to the plausibility of psychotic hallucinations. We sketch then a Plausibility of Hallucinations Scale, consisting of a 50-item questionnaire, which aims at evaluating the degree of plausibility of hallucinations. We also emphasize the utility of pointing out to the patient the several factors that contribute to the plausibility of his/her hallucinations, in the context of cognitive therapy for schizophrenia.

A Logical Defence of Maher’s Model of Polythematic Delusions

Noahs-Ark-delusionEnglish translation of a paper published in French in Philosophiques, autumn 2008, under the title “Une défense logique du modèle de Maher pour les délires polythématiques”.

In this paper, we proceed to describe a model for the formation and maintenance of polythematic delusions encountered in schizophrenia, which is in adequation with Brendan Maher’s account of delusions. Polythematic delusions are considered here as the conclusions of arguments triggered by apophenia that include some very common errors of reasoning such as post hoc fallacy and confirmation bias. We describe first the structure of reasoning which leads to delusions of reference, of telepathy and of influence, by distinguishing between the primary, secondary, tertiary and quaternary types of delusional arguments. These four levels of arguments correspond to a stage the nature of which is respectively instantial, inductive, interpretative at a monothematic level and interpretative at a polythematic level. We also proceed to identify accurately the fallacious steps in the corresponding reasoning. We expose then the role of apophenia in the elaboration of delusional ideas. Lastly, we describe the role played by the hallucinations in the present model.

Theory of Cognitive Distortions: Over-generalisation and Labeling

English translation of a paper published in French in the Journal de Thérapie Comportementale et Cognitive, 2009, 19-4, pages 136-140 under the title “Théorie des distorsions cognitives : la sur-généralisation et l’étiquetage”.

In a previous article (Complements to a theory of cognitive distorsions, Journal de Thérapie Comportementale et Cognitive, 2007), we introduced some elements aimed at contributing to a general theory of cognitive distortions. Based on the reference class, the duality and the system of taxa, these elements allow to define the general cognitive distortions as well as the specific cognitive distortions. This model is extended here to the description of two other classical cognitive distortions: over-generalisation and mislabelling. The definition of the two latter cognitive distortions is based on prior differentiation between three levels of reasoning: primary, secondary and ternary pathogenic arguments. The latter analysis also leads to define two other cognitive distortions which insert themselves into this framework: ill-grounded inductive projection and confirmation bias.

Theory of Cognitive Distortions: Personalisation

English translation of a paper published in French in the Journal de Thérapie Comportementale et Cognitive, 2010, 20-2, pages 51-55 under the title “Théorie des distorsions cognitives : la personnalisation”.

In a previous paper (Complements to a theory of cognitive distorsionsJournal de Thérapie Comportementale et Cognitive, 2007), we did present some elements aimed at contributing to a general theory of cognitive distortions. Based on the reference class, the duality and the system of taxa, these elements led to distinguish between the general cognitive distortions (dichotomous reasoning, disqualification of one pole, minimisation, maximisation) and the specific cognitive distortions (disqualifying the positive, selective abstraction, catastrophism). By also distinguishing between three levels of reasoning – the instantiation stage, the interpretation stage and the generalisation stage – we did also define two other cognitive distortions: over-generalisation and mislabelling (Théorie des distorsions cognitives : la sur-généralisation et l’étiquetageJournal de Thérapie Comportementale et Cognitive, 2009). We currently extend this model to another classical cognitive distortion: personalisation.

Theory of Cognitive Distortions: Application to Generalised Anxiety Disorder

grad-tag4-bw-bakEnglish translation and postprint (with additional illustrations) of a paper published in French under the title “Théorie des distorsions cognitives : application à l’anxiété généralisée” in the Journal de Thérapie Comportementale et Cognitive, 2008, 18, pp. 127-131.
This article follows the contribution to the general theory of cognitive distortions exposed in “Complements to a theory of cognitive distorsions” (Journal de Thérapie Comportementale et Cognitive, 2007). The elements described, namely the reference class, the duality and the system of taxa, are applied here to generalised anxiety disorder. On the one hand, these elements allow to describe the cognitive distortions which are specific to generalised anxiety disorder, consistent with recent work emphasising the role played uncertain situations relative to future events. On the second hand, they allow to define a type of structured reasoning, of inductive nature, which leads to the formation and maintenance of anxious ideas.

Complements to a Theory of Cognitive Distortions

Fig1English preprint of a paper published in French under the title “Compléments pour une théorie des distorsions cognitives”, in the Journal de Thérapie Comportementale et Cognitive, 2007, 17-2, pp. 84-88.

The purpose of this study is to describe a conceptual framework for cognitive distortions, which notably allows to specify more accurately their intrinsic relationships. This conceptual framework aims at inserting itself within the apparatus of cognitive therapy and of critical thinking. The present analysis is based on the following fundamental concepts: the reference class, the duality and the system of taxa. With the help of these three notions, each cognitive distortion can be defined. A distinction is also made between, on the one hand, general cognitive distortions and on the other hand, specific cognitive distortions. The present model allows then to define within the same conceptual framework the general cognitive distortions such as dichotomous reasoning, disqualifying a given pole, minimisation and maximisation. It also allows to describe as specific cognitive distortions: disqualifying the positive, selective abstraction and catastrophism. Furthermore, the present model predicts the existence of two other general cognitive distortions: the omission of the neutral and requalifying in the other pole.
