Emotion dysregulation and rumination are involved in the development, maintenance, and treatment of both posttraumatic stress disorder (PTSD) and sleep disturbances. We examined if and how these factors influenced the nature of the relationship between PTSD symptom severity and subjective sleep disturbances among trauma-exposed individuals. Using data gathered from a community sample of 199 trauma-exposed individuals (Mean age = 35.48; 59.80% female), we examined whether there were stronger significant associations between greater PTSD symptom severity and poorer sleep quality/lower sleep quantity at higher (vs. lower) levels of (1) negative emotion dysregulation and positive emotion dysregulation (both included in the same model) and (2) rumination. Participants recruited via Amazon's Mechanical Turk completed the PTSD Checklist for DSM-5, Brief Version of the Difficulties in Emotion Regulation Scale, Difficulties in Emotion Regulation Scale – Positive, Ruminative Thought Style Questionnaire, and sleep quality/quantity items from the Pittsburgh Sleep Quality Index. Results of simple and additive multiple moderation analyses showed that neither negative/positive emotion dysregulation nor rumination moderated the relationships between PTSD symptom severity and sleep quality/quantity. Exploratory analyses showed that negative emotion dysregulation (when examined independently) moderated the relationship between PTSD symptom severity and sleep quality. There were also significant associations between poorer sleep …

Violence and aggression continue to be both public health and economic concerns. The field of violence prediction has undergone a series of changes in an attempt to best assess risk including using unstructured clinical judgment, actuarial measures, and structured professional judgment. Although prediction has become more accurate with improved measures, a new generation has recently emerged with an emphasis on understanding violence, as opposed to merely predicting it, to shift the focus towards violence prevention. In addition to the creation of measures, researchers have sought to identify specific risk factors for aggression and violence including static and dynamic risk factors. Despite research demonstrating associations between neuropsychological and social-cognitive factors, violence risk measures continue to omit these variables. The current study developed a multi-faceted, theoretical model of aggression including social-cognitive, neuropsychological, personality, and psychiatric factors. A community, male sample (N = 1,192) collected through Amazon's MTurk responded to a series of self-report measures and neuropsychological tasks. Utilizing structural equation modeling (SEM), I created a model predicting aggression. Several important paths were significant including from entity theory to aggression, mediated by hostile attribution bias, schizotypy to aggression, mediated by both hostile attribution bias and disinhibition, substance use to aggression mediated by disinhibition, …

The decision of the landmark United States Supreme Court case Miranda v. Arizona (1966) established procedural safeguards to protect custodial suspects' 5th and 6th Amendment rights through requiring provision of what is now known as the Miranda warnings prior to interrogation. Suspects may elect to waive their rights once informed; however, research indicates that many individuals have inadequate knowledge and appreciation of their Miranda rights and consequences of waiving them. Miranda abilities and individual factors are critical factors in determining the validity of Miranda rights waivers. Researchers implicated many factors as influencing waiver decisions (e.g., intellectual ability, psychopathology, age); however, the differential impact of racial/ethnic identity is relatively unexplored. The importance of the investigation of race/ethnicity in Miranda abilities and decisions is underscored by the established differences in perceptions of police officers for racial/ethnic groups. Additionally, scholars have identified a potential presence of stereotype threat contributing to detrimental interrogation decisions. The current study advances previous research through examining the influence of racial/ethnic identity on Miranda abilities and waiver decision. This study also seeks to further the understanding of the effects of perceptions of police officers and presence of stereotype threat through investigate the role of those variables in Miranda abilities …

The hierarchical taxonomy of psychopathology (HiTOP) is a novel classification system that adopts both a dimensional and hierarchical approach to psychopathology to address shortcomings. However, the HiTOP framework is descriptive in nature and requires additional research to consider potential mechanisms for the onset and maintenance of psychopathology, such as cognitive-behavioral emotion regulation strategies. To redress this gap, a sample of 341 adults who endorsed ongoing mental health concerns completed self-report measures of emotion regulation strategies and psychopathology. The data revealed a three-spectra HiTOP model consisting of internalizing, thought disorder, and antagonistic externalizing. Results found that psychopathology was most strongly associated with avoidance, catastrophizing, expressive suppression, and self-blame. In contrast, adaptive strategies were generally unrelated to the HiTOP spectra. This pattern was strongest for internalizing, distress, and detachment. Fewer, yet noteworthy unique relationships between the strategies and specific spectra/subfactors were also found. These findings suggest that psychopathology may be best conceptualized as an overutilization of maladaptive emotion regulation strategies. Furthermore, the results indicate there is added benefit to considering these strategies within a hierarchical approach to psychopathology. These associations alert clinicians to potential treatment targets and contribute to an ongoing literature that seeks to identify underlying mechanisms of the structure of …

The current dissertation had three primary objectives, categorized into two MTurk studies with capital juror-eligible community members: (a) cross-validate the psychometric properties of the JQVV, (b): explore the role of legal attitudes via the JQVV in mock capital sentencing decisions, and (c): examine the JQVV's ability to detect juror social desirability in capital voir dire. Impressively, Study 1 (N = 552) and Study 2 (N = 313) provided strong and consistent evidence for the JQVV's reliability and construct validity. In the mock juror paradigm, punitive legal attitudes on the JQVV (i.e., Crime-Neg, Convict, and Death-Pos), did not directly affect sentencing decisions, however they indirectly influenced the perception of nearly all other legally relevant variables (e.g., evidence type). For example, participants with more punitive criminal justice attitudes evaluated aggravating evidence more favorably which, in turn, increased death sentence verdicts. Study 1 also underscored the concerningly low levels of comprehension jurors have regarding judicial instructions and other relevant legal knowledge (e.g., the definition of aggravating). In Study 2, the support-life and support-death groups evidenced divergent patterns of social desirability, although support-death participants did not dramatically alter their scores between the genuine and social desirability condition. Additionally, the JQVV Pros-Cyn and Justice-Pos scales …

Despite significant progress in the acceptance and celebration of LGBTQ+ individuals, there is overwhelming evidence that sexual minorities still face disproportionate levels of health inequity compared to their heterosexual peers. Relative to their heterosexual peers, LGBTQ+ emerging adults may encounter unique challenges with discrimination, stigma, and limited social support as they navigate changes in their educational and occupational environments. Additionally, within the broader public health and LGBTQ+ mental health literature, little is known about the mental health service utilization of sexual minority emerging adults. To address these empirical gaps, a sample of 98 LGBTQ+ emerging adults completed self-report measures of heterosexist discrimination experiences, mental health symptoms, LGBTQ+ positive identity, LGBTQ+ community connectedness, and mental health service utilization. The present study found that LGBTQ+ positive identity and LGBTQ+ community connectedness did not attenuate the significant positive relationship between discrimination and negative mental health outcomes. The present study also found that LGBTQ+ positive identity predicted greater likelihood of mental health service utilization, whereas LGBTQ+ community connectedness did not. Finally, exploratory qualitative analyses yielded deeper understanding of relationships between LGBTQ+ positive identity, LGBTQ+ community connectedness, mental health service utilization, and resilience among sexual minority emerging adults. Implications and future directions for empirical research …

Using a multimethod-multimodal approach, this study compared the contributions of executive function (EF) abilities (Go No-Go, Visual Search, 2-Back task, and Task Switching) to narrative comprehension tasks (False Belief, Strange Stories, Self-Reported Theory of Mind Inventory [TOMI-SR]) and a narrative production task (interpersonal decentering) in a sample of young adults. Separate regression models were conducted for each theory of mind (ToM) measure with EF measures as predictor variables and empirically selected demographic variables controlled. As expected, in this college student sample (N = 110), False Belief demonstrated a ceiling effect and was not associated with any EF ability. Task Switching and 2-Back accounted for significant variance in Strange Stories. No EF task significantly predicted performance on TOMI-SR or interpersonal decentering. Both story comprehension tasks (False Belief and Strange Stories) were significantly associated, but these tasks were not correlated with either self-reported ToM or interpersonal decentering. Several unanticipated demographic associations were found; having more siblings and English proficiency accounted for significant variability in Strange Stories; education, presence or absence of self-disclosed autism diagnosis and mental health diagnosis explained a large portion of variance in TOMI-SR; interpersonal decentering maturity differed significantly between cisgender men and cisgender women. Lastly, interpersonal decentering number of …

This study used an archival data set of 26 healthy adult immigrants from a sub-Saharan African country to the United States (Mage 39.0, SD = 11.36; Meducation 16.33, SD = 2.88; 40.7% male). Additional archival data was used for 32 healthy African American adults (Mage 34.06, SD = 11.18; Meducation 16.16, SD = 2.49; 53.1% male). A bivariate correlation indicated that acculturation to African culture, as measured by the mBIQ (M 49.29, SD = 8.66), was significantly positively correlated with ethnicity, r = .632, p = .000, ηp2 = 0.399. Two-way ANOVAs revealed that African Americans were able to name more animals than African immigrants (F(1, 54) = 4.82, p = 0.32, ηp2 = 0.82) and exhibited greater organizational skills during a task of cognitive set shifting and problem solving than African immigrants, regardless of level of acculturation (F(1, 54) = 4.47, p =.039, ηp2 = 0.078). In contrast, African immigrants scored higher than African Americans on indigenous fruit (F(1, 54) = 7.60, p =.008, ηp2 = 0.123) and object naming (F(1, 54) = 5.59, p =.022, ηp2 = 0.094). Results of the study concluded that there are small variance effects in language tasks as well as strategy-based approaches to …
