Influence du monde affectif et interpersonnel de l’individu dans la relation entre la dépendance, l’automutilation et ses fonctions
The objective of this thesis is to shed light on what may lead a dependent person who fears abandonment to engage in self-injury. Psychological models of object relations and attachment have shown that self-injury is empirically associated with fear of abandonment via dependency and attachment anxiety. However, the nature of this relationship has yet to be thoroughly explained. Having defined and contextualised self-injury, a theoretical explanation is proposed through object relations, attachment and experiential avoidance functions of self-injury, all with the goal of better understanding what can influence a dependent individual to self-injure. This thesis suggests that individuals who are dependent and afraid of being abandoned might use self-injury to regulate negative emotions associated with their perception of abandonment, separation or rejection. Theoretically, this influence of self-injury could occur through intrapersonal and interpersonal functions, such as affect regulation, self-punishment and interpersonal influence, as well as autonomy avoidance. These functions might serve to protect internal representations of dependence and thus, reduce subjective feelings of abandonment.  To test these theoretical proposals, 58 outpatient participants completed, among other measures, the Depressive Experiences Questionnaire (DEQ), the Inventory of Statements About Self-Injury (ISAS) and the Revised Diagnostic Interview for Borderlines (DIB-R). Results showed a relationship between anaclitic neediness and self-injury frequency, which was explained by mediator effects of both affective and interpersonal problems. Furthermore, this type of dependency was found to be specifically associated with marking distress, anti-dissociation, interpersonal influence and autonomy avoidance functions of self-injury. These findings suggest that anaclitic neediness favours the experience of affective and interpersonal difficulties, which in turn increase the frequency of self-injury. Results also suggested that self-injury associated with this type of dependency might serve to regulate internal affective states, to influence the interpersonal environment and to avoid autonomy. Affect regulation and self-punishment functions were endorsed by the majority of individuals who self-injured, regardless of their level of dependence. While these two functions are associated in theory to dependency issues that underpin self-injury for some individuals, analyses indicated that these functions also contribute to self-injury behaviour in people who do not fear abandonment specifically.
