Résumé
In this study, we assessed attention-deficit/hyperactivity disorder (ADHD) diagnosis in adults from the social labeling perspective of deviance, resulting from the actions of moral entrepreneurs (Howard S. Becker).As an object of several moral entrepreneurs with distinct interests, ADHD diagnosis in adults can be defined as a multidimensional deviance, at the crossroads of medical and social norms.In our research, the stigmatization that precedes diagnosis gives ADHD adults the status of a social deviant. These adults, as part of a social reaction fostered by an incomplete medical context, increased medicalization and identity-building injunction, set in motion a moral enterprise of reparation, by instrumentalizing the diagnostic process and establishing new norms to serve their own interest. This medicalization process relies on a peer group that intermingles diagnosed and undiagnosed ADHD adults and intervenes from the very start of the search for stigma identification. The social support that emanates from this group initiates a psychosocial healing and potentiates the action of moral entrepreneurs.However, this approach is not insignificant: as part of a quest for social integration, the moral enterprise of adults with ADHD not only conveys a logic of community interest, but above all bears witness to a psychosocial suffering linked to a society refusing to move away from a perspective of standardization in favor of an acceptance of singularities.
