Current Research Projects

  • The Integrated Metatheoretical Model of Addiction: Towards a general model of addiction. PhD Thesis, Unisa, Department of Psychology.                                               
    Abstract:This research project aims to develop a general theory of addiction and adapt this theory to clinical practice. The objective of this study will be pursued through the exploring the systematic connections and relationships between the diverse etiological and explanatory paradigms of addiction, and to systematise those into an overarching integrative meta-theory (general theory) of addiction and its treatment. This goal will be achieved through analysing several theoretical orientations, identifying their core conceptual themes. From these core conceptual themes or lenses, an integrative meta-theory of addiction (general theory of addiction) will be constructed. The specific objectives of the study are to: i) perform a multi-paradigmatic review and analysis of the theoretical literature on addiction and to identify the core conceptual elements of the extant theories; ii) develop a general theory for addiction, tentatively titled the ‘integrated metatheoretical model of addiction’; iii) apply the integrated metatheoretical model of addiction to addiction treatment. This study is theoretical, and the discussion is based entirely on published literature. It involves a conceptual analysis of existing theories of addiction. Considering that theories are the data to be analysed, this type of conceptual analysis is known as meta-theorising. A maximum variation sampling procedure will be used to identify the theories to be included in the study. The chosen theories will be found by searching scientific literature databases. This study will contribute to the longstanding aim for an integrative model of addiction or a general theory of addiction.

  • Ideology Addiction: I am researching the relationship between ideology and addiction. I propose that ideologies are psychoactive and potentially addictive. Ideology addiction can be understood as a type of ideological possession and zealotry, with deleterious consequences for the individual and society. An individual in the grips of an ideology addiction exhibits psychological and behavioral patterns common to all addicted populations. From a psychodynamic perspective, ideology addiction can be understood as the result of a narcissistic disturbance of self experience and deficits in self capabilities. Consequently, the activism of an ideology addict is fundamentally a narcissistic project. A misguided attempt at self repair and satisfaction of archaic narcissistic needs, and seldom motivated by the ideals of the ideology.
