The relationship of personality disorders and persistent post concussive syndrome in mild head injuryAlyman, Cheryl Ann 05 June 2017 (has links)
The relationship of personality disorders and persistent post concussive syndrome
(PPCS) in mild head injury was investigated. Personality disorders were measured
with the Millon Clinical Multiaxial Inventory-II (MCM-II). Mild head injury referrals
were compared to a moderate head injury group, (n=46), and to a non-head injured
neurological control group, (n=93). There was little evidence to suggest that the mild
traumatic brain injury (TBI) group had more personality disorders than either of the
two comparison groups. The mild TBI group did endorse more passive-aggressive,
aggressive-sadistic, self-defeating and borderline personality traits; however, the
overall scores were below ranges which indicate a personality disorder. The
relationship between personality disorders (the MCMl-Il) and emotional status, as
measured by the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) was also
examined. Neither maladaptive personality characteristics or psychological distress
were related to performance on neuropsychological tests. The results are discussed
within the context of physiological and psychological determinants of the PPCS. / Graduate

The Association between Reported Denominational Affiliation and Psychiatric Diagnosis: a Study of First Admissions to a Private Psychiatric Hospital, 1960-1963Cochran, Carole Makeig 01 1900 (has links)
The present study examines the relationship of diagnosis and denominational affiliation in light of the work of Charles Glock and Rodney Stark. The major hypothesis of the study was that diagnoses of first admissions to Timberlawn sanitarium would vary by denominational affiliation.

Precursors for schizophrenia : are schizotaxia and schizotypy related?Whitehead, Kirsty Victoria, n/a January 2006 (has links)
Meehl�s (1962, 1989, 1990b) schizotypy and Tsuang et al.�s (1999b, 2000a, 2000b) schizotaxia are fundamentally different notions of the schizophrenia precursor. Both represent a categorical precursor but differ in the nature of their relationships to schizophrenia. Specifically, schizotypy is dimensional, unchanging despite the presence or remission of schizophrenia. In contrast, schizotaxia is a transitional precursor; the presence of schizophrenia signals the end of schizotaxia. There are also differences in the way in which risk is determined. Schizotypy is reflected in a variety of information processing and experiential aberrations, is typically assessed using self-report measures, and is best identified using taxometric analyses. In contrast, schizotaxia is characterised by negative symptoms of schizophrenia and neurocognitive impairment, can be assessed using standardised clinical measures, and is diagnosed at the individual case level.
The aim of Phase 1 of this study was to investigate the manifest structure of Meehl�s schizotypy in a sample of psychiatric patients. The aims of Phase 2 were to determine if schizotypy group membership was associated with poorer functioning and to determine the nature of the relationship between Meehl�s (1962, 1989, 1990b) schizotypy and Tsuang et al.�s (1999b, 2000a, 2000b) schizotaxia. Participants in Phase 1 were 109 psychiatric patients and all completed a self-report measure of schizotypy, the Thinking and Perceptual Style Questionnaire (TPSQ; Linscott & Knight, 2004). Multivariate taxometric analyses of TPSQ subscales yielded evidence of a manifest group structure within the sample. The prevalence of the latent group, presumed to reflect schizotypy, was estimated to be 32% (SD = 8%), as yielded by MAXCOV analyses. MAXCOV analyses also yielded a mean indicator validity of 1.02; variance of 7; base rate estimates of .08; and a goodness of fit index of .98. MAMBAC analyses yielded a mean base rate of 56% (SD = 18%).
Twenty-nine participants from Phase 1 took part in Phase 2. Fourteen were from the schizotypy group (had a p value of .85 or higher of schizotypy group membership) and 15 from the nonschizotypy group (had a p value of .03 or lower of schizotypy group membership). Participants completed tests of attention, verbal memory, and executive functioning. Negative symptoms of schizophrenia were also rated and diagnosis was determined using a diagnostic interview. The schizotypy group was significantly impaired relative to the nonschizotypy group on neuropsychological test scores spanning domains of attention, verbal memory, and executive functioning. A current DSM-IV diagnosis was made for 71% of the schizotypy group and 43% of the nonschizotypy group. Individuals were classified as having met criteria for schizotaxia if they had a negative symptom impairment and a neuropsychological impairment in two domains. A total of 7 people of 29 met criteria for schizotaxia, 6 of these people were from the schizotypy group. There was statistical evidence that Meehl�s (1962, 1989, 1990b) schizotypy and Tsuang et al.�s (1999b, 2000a, 2000b) schizotaxia are not independent. The proposed precursors for schizophrenia may reflect the same construct, not separate entities. Limitations and implications of these results are considered.

Mechanisms of Borderline Personality Disorder: The Role of Identity DiffusionLowmaster, Sara Elizabeth 16 December 2013 (has links)
Borderline personality disorder (BPD) is a disabling psychiatric condition that causes pervasive and enduring impairments in social and occupational functioning. Previous literature has outlined the core components of the disorder to include disturbances in affect regulation, identity problems, disrupted interpersonal relationships, and impulsive behavior. While several theories have postulated the primacy of one component in driving the remaining components, the etiological and maintaining mechanisms of BPD are poorly understood. Therefore, the present study examined the primacy of one of these components, identity disturbance, in eliciting changes in the affective, interpersonal, and impulsive components of the disorder. The current study employed an experimental manipulation of identity coherence in 388 undergraduates who were screened for high or low levels of borderline personality features. All participants completed measures of affect prior to and immediately following the manipulation and then completed a GoStop task of impulsivity and an interpersonal trust task in a counterbalanced order. The results suggest individuals with high levels of borderline personality features generally report reduced self-concept clarity and are more susceptible to efforts to alter the coherence of their identity than those with lower levels of borderline personality features. Destabilization of identity coherence led to greater difficulties inhibiting behavior in those with high levels of borderline features, whereas it improved behavioral control in those with low levels of borderline features. These results support theoretical articulations of BPD that indicate impulse control problems are a means of regulating one’s internal self-state. Contrary to some characterizations of the disorder, there was no evidence to suggest that alterations of identity coherence led to an exaggerated emotional response or disturbed interpersonal behavior. This finding is consistent with a number of studies examining affective reactivity to emotion induction procedures, interpersonal stimuli, and now alterations in identity coherence indicating that BPD is better characterized by severe, trait negative affect valence compared to healthy controls rather than hyper-reactivity. Moreover, the failure of interpersonal behavior to vary as a function of borderline personality status or experimental task type indicates the importance of dynamic influences during interactions as potential sources for variability in behavior. Although further research is needed to clarify the mechanisms linking identity, affective dysregulation, and interpersonal behavior; psychosocial interventions aimed at maintaining and developing a stable sense of identity may be beneficial for reducing the impulsive behaviors in BPD, which are potentially most critical for establishing the patient’s safety.
