The current study provides convergent, discriminant, and incremental validity data for a measure of schizotypia from the perspective of the Five-Factor Model (FFM) of general personality structure. Nine schizotypia facet scales were constructed as maladaptive variants of respective facets of the FFM (e.g., Aberrant Ideas as a maladaptive variant of FFM Openness to Ideas). On the basis of data from 143 undergraduates the convergent validity of these nine facet scales was tested with respect to 11 established measures of schizotypia and the respective facets of the FFM. Discriminant validity was tested with respect to other personality disorders and facets from other FFM domains. Incremental validity was tested with respect to the ability of the FFM schizotypia facet scales to account for variance in two established measures of schizotypia, after variance accounted for by respective FFM facets and other established measures of schizotypia were first removed. The findings support the validity of these new facet scales as measures of schizotypia and as maladaptive variants of the FFM.

The current thesis tests empirically the relationship of the dimensional trait model proposed for the fifth edition of the American Psychiatric Association’s (APA) Diagnostic and Statistical Manual of Mental Disorders with five-factor models (FFM) of personality disorder (PD). The DSM-5 Personality and Personality Disorders Work Group proposes to diagnose the disorders largely in terms of a 25 trait dimensional model organized within five broad domains (i.e., negative affectivity, detachment, antagonism, disinhibition, and psychoticism). Consistent with the authors of DSM-5, it was predicted that negative affectivity would align with FFM neuroticism, detachment with FFM introversion, antagonism with FFM antagonism, disinhibition with low FFM conscientiousness and, contrary to the authors of DSM-5, psychoticism would align with FFM openness. Suggested changes in trait placements according to FFM of PD research were also tested. Four measures of five factor models of general personality were administered to 445 undergraduates along with the Personality Inventory for DSM-5. The results of the present study provided support for the hypothesis that all five domains of the DSM-5 dimensional trait model are maladaptive variants of general personality structure, including the domain of psychoticism; however, the findings provided mixed support for suggested trait placement changes in the DSM-5 model.

While the overall stability of personality across the lifespan has been well-documented, there is also evidence of meaningful personality change. This is particularly true when individuals are going through periods of developmental transition. Over time, one sees incremental changes not just in behavior but in basic personality as well. 1,906 early adolescents were assessed for urgency scores, levels of maladaptive behavior engagement (drinking, smoking, and binge eating), and pubertal status every six months for four years. Zero-Inflated Poisson structural equation modeling (SEM) was used to test the model of reciprocal influence between behavior and personality. Across most six-month intervals over the course of the four-year study, urgency predicted increased engagement in the maladaptive behaviors. Strikingly, the reverse was true as well: engagement in behaviors predicted subsequent increases in urgency, which is otherwise a stable personality trait. This study is the first to find reciprocal prediction between engagement in maladaptive, risky behaviors and endorsement of the maladaptive personality trait of urgency during the early adolescent years. One implication of these findings is the apparent presence of a positive feedback loop of risk, in which maladaptive behaviors increase high-risk personality traits, which in turn further increase the likelihood of maladaptive behaviors.

abstract: The link between victimization and offending is well established in the literature, yet an unexplored causal pathway within this relationship is concerned with why some individuals engage in maladaptive coping in response to victimization. In particular, those with low self-control may be attracted to problematic yet immediately gratifying forms of coping post-victimization (e.g., substance use), which may increase their likelihood of violent offending in the future. Using three waves of adolescent panel data from the Gang Resistance Education and Training (GREAT) program, this research examines: (1) whether individuals with low-self control are more likely to engage in substance use coping following violent victimization, and (2) whether victims with low self-control who engage in substance use coping are more likely to commit violent offenses in the future. The results from negative binomial regressions support these hypotheses, even after controlling for prior offending, peer influences, prior substance abuse, and other forms of offending. The implications for integrating general strain and self-control theories, as well as for our understanding of the victimization-offending overlap, are discussed. / Dissertation/Thesis / M.S.

abstract: General Strain Theory (GST) posits that different types of strain lead to different types of negative emotions, some of which increase the likelihood of maladaptive coping. Much research on GST has focused on anger and depression. Far less attention has been directed toward other negative emotions, including anxiety and envy. The current study uses cross-sectional data from surveys administered to a university-based sample (N = 500) to address these voids and explore gender differences in the effects of strain and negative emotions in maladaptive coping. Results indicate that when gender differences existed in levels of strain and negative emotions, females experienced higher levels than males. Strain significantly predicted all four measures of negative emotions examined in this study. Finally, different negative emotions were found to have differing effects on different measures of maladaptive coping. Implications of this study for theory, future research, and policy are discussed. / Dissertation/Thesis / Masters Thesis Criminology and Criminal Justice 2015

abstract: The relationship between stress and policing has long been established in literature. What is less clear, however, is what departments are doing to help officers deal with the stress that comes with the job. Looking at a small Southwestern police agency and using a modified version of Speilberger’s (1981) Police Stress Survey, the present study sought to examine stressors inherent to policing, as well as to identify departmental services that may be in place to help officers alleviate those stressors and whether or not police officers would choose to take part in the services that may be offered. The findings suggest that a shift in stress in policing is occurring with operational stressors being reported at higher levels than organizational stressors, contrary to previous research. / Dissertation/Thesis / Masters Thesis Criminology and Criminal Justice 2016

This study investigated the relationship between maladaptive behavior, defined as referral to counseling, and the Adlerian construct of birth order. The birth order variables examined were ordinal position, sex of subject, family density, family size, socio-economic status, intactness of family, age of mother, and sex of sibling. The subjects in this study were 217 school-aged children with academic and/or behavior problems who were referred to an interdisciplinary guidance center. The subjects were assigned to counseling or no-counseling groups on the basis of an interdisciplinary evaluation and staffing, which included an extensive battery of academic and psychological tests.

Tinnitus is a phantom auditory perception characterized by a ringing sound in either one or both ears. It is a common disorder most often associated with hearing loss and can have a severe impact on a person's quality of life. There is currently no cure and no efficient therapeutic options. There is little known about the neural mechanisms underlying the generation of tinnitus but a better understanding of its neural basis could greatly benefit the development of efficient treatment methods. This literature study aims to explore the neural mechanisms of tinnitus in terms of generation, perpetuation, and perception. Cochlear dysfunction, changes in neuronal firing rates and oscillatory properties, hyperactivity, lack of inhibitory activity and plasticity in auditory-limbic structures have been associated with tinnitus and may be a part of a crossmodal network involved in generating, perpetuating and perceiving tinnitus, through maladaptive CNS plasticity. New developing treatment methods aim to modulate and re-route tinnitus-related plasticity, however, this leads to treatment difficulties due to the crossmodal nature of the tinnitus pathophysiology. These difficulties will be further examined in the discussion.

Actualmente, se observa un crecimiento en los índices de violencia en la ciudad de Lima. Los especialistas forenses indican que los agresores y víctimas crecen en ambientes familiares y sociales donde no se satisfacen las necesidades emocionales. Por tal motivo, se abordó la problemática a partir de los esquemas maladaptativos tempranos los cuales se generan en las primeras etapas de la vida e influyen en la vida adulta. En ese sentido, el principal objetivo de esta investigación fue describir los esquemas maladaptativos tempranos en investigados por algún delito en Lima. Este estudio se realizó desde un enfoque cuantitativo de tipo descriptivo. Por ello se aplicó el Cuestionario de Esquemas de Young 3era edición (versión reducida) en una muestra de 20 personas investigadas por algún delito, siendo 8 presuntas víctimas y 12 presuntos victimarios. Los resultados indican que los EMT con mayor prevalencia son el de Estándares inflexibles (70%) y Pesimismo (55%). Según la condición del participante, las presuntas víctimas presentan mayormente Grandiosidad (63%) y Búsqueda de Aprobación (63%); mientras que, en los presuntos victimarios, la mayor prevalencia está en Vulnerabilidad (67%) e Insuficiente autocontrol (58%). El estudio presenta limitaciones en relación al tamaño reducido de la muestra ya que no permite hacer una generalización de los resultados, por lo que se sugiere ampliar la muestra para futuras investigaciones. / Currently, there is a growth in the rates of violence in the city of Lima. Forensic specialists indicate that aggressors and victims grow up in family and social settings where emotional needs are not met. For this reason, the problem was addressed from the early maladaptive schemes which develop in the early stages of life and influence adult life. In this sense, the general objective of this study was to describe the early maladaptive schemes in people investigated for a crime in Lima. This study was carried out from a descriptive quantitative approach. For this reason, the Young Schemes Questionnaire 3rd edition (reduced version) was applied to a sample of 20 people investigated for a crime, with 8 alleged victims and 12 alleged perpetrators. The results indicate that the EMT with the highest prevalence are that of inflexible Standards (70%) and Pessimism (55%). According to the condition of the participant, the alleged victims present mostly Grandiosity (63%) and Search for Approval (63%); while, in the alleged perpetrators, the highest prevalence is in Vulnerability (67%) and Insufficient self-control (58%). The study has limitations in relation to the reduced sample size since it does not allow a generalization of the results, so the sample will be expanded for future research. / Trabajo de investigación
