The purpose of this quantitative study was to determine to what extent the 4 M-PULSE scale scores (interpersonal difficulties, unprofessional conduct, discharge of weapon, and inappropriate use of weapon) account for variance in the MMPI-2RF (aggression and antisocial) subscales scores. Archival data was provided by a private business that conducts these screenings for multiple law enforcement organizations (local and state). Law enforcement candidates (N = 127) were evaluated by a private business during the prehiring psychological screening process using the M-PULSE and MMPI-2RF to assess their risk factors for employment as law enforcement officers. Using Social Learning theory as the basis, the scores from the 2 measures were provided for regression analysis to determine what effect the M-PULSE factors had on the MMPI-2RF factors. This research did not find any significant effect on either MMPI-2RF factor by the 4 M-PULSE factors. This study adds to the growing body of knowledge of law enforcement psychological screening processes and how different measures provide critical information on personality, aggression, and risk factors that should be considered for individuals seeking employment in a law enforcement position. This study has implications for positive social change by increasing understanding of how current psychological screening processes determine suitability of candidates and help to ensure that individuals who would put the public and law enforcement organizations at higher risk should be screened out prior to completion of any law enforcement training.

La recherche que nous avons développée dans notre thèse a eu pour objectif l’étude des psychoses dissociées à travers une approche clinique et projective comparées. C’est à travers une révision de la littérature des psychoses, que nous avons, dans un premier temps, mis en évidence les diverses positions au sein de la nosographie psychiatrique dans un contexte historique, puis actuel. Nous avons croisé cette perspective à une approche issue de l’application du modèle métapsychologique, dont les jalons ont été posés par Freud (1911, 1920, 1924, 1940). En outre, nous avons mis en évidence une opposition entre Freud et Bleuler à travers leurs échanges épistolaires parus en 2016, et cela à propos de la question de l’autisme. La recherche que nous avons conduite est composée de plusieurs études. La première étude vise la comparaison statistique des indicateurs au test de Rorschach (Nina Rausch de Traubenberg, 1990) entre la population tout-venant ([n=310], (de) Tychey et al., 2012) et entre la population psychiatrique psychotique (n=81). Tous les diagnostics ont été réalisés en double aveugle au test de Rorschach et selon une double approche nosographique dans la clinique (psychanalytique et psychiatrique). La seconde étude est une analyse qualitative contrastée, constitué de 5 cas cliniques, consacrée à une investigation approfondie des psychés de cas cliniques exemplaires représentatifs des trois sous-groupes de référence de la population de l'étude. La troisième étude est longitudinale sur un cas clinique à 24 mois d’intervalles en test/re-test nous permettant de valider la fiabilité du diagnostic de paranoïa, dont nous assistons pourtant à l’évanouissement nosographique.Pour conclure, nous avons dégagé et validé l’indicateur de la représentation de soi intitulé : le degré de représentation de soi entière unitaire, qui permet notamment de discriminer les structures et les organisations entre elles. La psychose dissociée, reconnue pour représenter la faillite du narcissisme primaire est apparue comme une population adéquate au développement de ces travaux sur l’évaluation du narcissisme / It is thought a depth psychosis literature review, that we have, in a first time, highlighted various positions within the psychiatric nosography, in an historic and then, in a current context. We cross a perspective called objective to an approach more subjective, however very rewarding: the metapsychological model, whose milestones were thrown by Freud (1911, 1920, 1924, 1940). In addition, we highlighted an opposition between Freud and Bleuler thought their epistolary exchanges published in 2016 in French. This about, question of autism that Freud (1911) designated as well as a retreat of the libido on the Ego; contrarily to Bleuler (1911). To us, that epistemological and theoretical cleavages, have influenced the current nosography (DSM-5, A.P.A., 2013). The empirical research developed in this thesis, aimed at the study of dissociated psychosis through a clinical and projective compared approaches. Indeed, this research is composed by many studies: the first was aimed at the statistical comparisons of Rorschach’s indicators (Nina Rausch de Traubenberg, 1990) between non-clinical population ([n= 310], (de) Tychey et al., 2012) and clinical population, psychiatrist, and more specifically: psychosis dissociated ([in]patient [n= 81]). Within the first study, in a second time, we proceeded to the statistical comparisons between the three subgroups of the sample, constitute of: 25 subjects diagnosed with paranoia, 30 subjects diagnosed with schizophrenia and 26 diagnosed with paranoid schizophrenia. All diagnostics were realized in double bind et and according to a double approach (psychoanalytic and psychiatrist). The second study is a qualitative analysis contrasted, devoted to the deeply psychic investigation of exemplary clinical cases, representatively of three subgroups from the population’s study (paranoia; schizophrenia paranoid; pure schizophrenia). The sample is itself constituted of limits’ subgroups suffering from psychotic decompensations and hospitalized on a long court. In the qualitative study of clinical contrasted cases, we presented firstly, a subject from a pure paranoia structure: Catherine, an autopunitive feminine paranoia case.Secondly, we presented the analysis of a clinical picture from schizophrenic structure: Joseph, from which megalomaniac Ego and invasive delirium will surely arrested the lector; and finally, we analysed a pure schizophrenia case: Doug, which psychic desert particularly challenges us in conter-transferential’s dynamic. Then, to illustrated closer that we understand by sliding of an a-structure to a dissociated psychosis (and not to a melancholic proceed, as well as that is permitted by Bergeret [1974]), we analysed the cases of Jordan and Ali. Ali was initially inscribed in an a-structure (Bergeret, 1974), from which he decompensed secondarily in a paranoiac organisation; Jordan on other hands, decompensed secondarily in a pure schizophrenia
