Description
Approximately one-third of Iraq and Afghanistan veterans develop mental health problems, yet only 35-40% of those with mental disorders are seeking mental healthcare (Hoge, et al., 2004; Vogt, 2011). Military spouses may be an important resource for facilitating treatment seeking (Warner, et al., 2008), especially if service member mental health issues are impacting the marriage. Military spouses might be hesitant to encourage service member help-seeking, however, due to perceived threat of adverse military career consequences. For this study, 62 military wives completed an online survey. As part of the survey, participants were randomly assigned to one of four vignettes containing a description of a hypothetical military husband with mental health symptoms. Each vignette presented different combinations of marital conflict (high versus low) and service member concerns about adverse career consequences (high versus low). Wives rated on a five-point scale how likely they were to encourage the hypothetical military husband to seek help. It was hypothesized that spouses would be more willing to encourage help-seeking when concerns about adverse military career consequences were low and marital distress was high. No main effects or interaction effect were found for marriage and career. Perceived stigma about seeking mental health treatment in the military, psychological identification as a military spouse, and experience and familiarity with military mental healthcare policies failed to moderate the relationship between marital conflict, career concerns, and encouragement of help-seeking. Correlational analyses revealed that (1) greater experience with military mental healthcare (first- or secondhand), and (2) greater perceptions of stigma regarding seeking mental healthcare in the military each were associated with decreased perceptions of military supportiveness of mental healthcare. Therefore, although the experimental manipulation in this study did not lead to differences in military spouses' encouragement of a hypothetical military service member to seek mental health services, other findings based on participants' actual experiences suggest that experiences with military mental healthcare may generate or reinforce negative perceptions of military mental healthcare. Altering actual experiences with military mental healthcare, in addition to perceptions of stigma, may be a useful area of intervention for military service members and spouses.

Description
Researchers have found inconsistent effects (negative or positive) of social relationships on self-control capacity. The variation of findings may depend on the aspects of social relationships. In this study, rather than examining overall social relationships and self-control, characteristics in social relationships were clearly defined, including social support, social connection and social conflict, to determine their specific effects on self-control. An online survey study was conducted, and 292 college students filled out the survey. For data analysis, path analysis was utilized to examined the direct effect and indirect effect from social relationships to self-control. Results showed social connection and social conflict may indirectly associate with self-control through stress, but social support does not. It may suggest, in traditional stress buffering model, it is the social connection in social support that really reduce the stress. Concerning the direct effects, social support and social connection were significantly associated with self-control directly, but social conflict does not. This result may support the Social Baseline Theory that positive social relationships have direct regulating effects. Results are good for guidance of experimental manipulation of social relationships in study of social influences of self-control.

Description
As threats emerge and change, the life of a police officer continues to intensify. To better support police training curriculums and police cadets through this critical career juncture, this thesis proposes a state-of-the-art framework for stress detection using real-world data and deep neural networks. As an integral step of a larger study, this thesis investigates data processing techniques to handle the ambiguity of data collected in naturalistic contexts and leverages data structuring approaches to train deep neural networks. The analysis used data collected from 37 police training cadetsin five different training cohorts at the Phoenix Police Regional Training Academy. The data was collected at different intervals during the cadets’ rigorous six-month training course. In total, data were collected over 11 months from all the cohorts combined. All cadets were equipped with a Fitbit wearable device with a custom-built application to collect biometric data, including heart rate and self-reported stress levels. Throughout the data collection period, the cadets were asked to wear the Fitbit device and respond to stress level prompts to capture real-time responses. To manage this naturalistic data, this thesis leveraged heart rate filtering algorithms, including Hampel, Median, Savitzky-Golay, and Wiener, to remove potentially noisy data. After data processing and noise removal, the heart rate data and corresponding stress level labels are processed into two different dataset sizes. The data is then fed into a Deep ECGNet (created by Prajod et al.), a simple Feed Forward network (created by Sim et al.), and a Multilayer Perceptron (MLP) network for binary classification. Experimental results show that the Feed Forward network achieves the highest accuracy (90.66%) for data from a single cohort, while the MLP model performs best on data across cohorts, achieving an 85.92% accuracy. These findings suggest that stress detection is feasible on a variate set of real-world data using deepneural networks.

Description
When questions about a person’s mental state arise in court, psychologists are often called in to help. Psychological assessment tools are routinely included in these evaluations to inform legal decision making. In accordance with the Daubert standard, which governs the admissibility of expert testimony, courts are obligated to exclude evidence that relies on poor scientific practice, including assessment tools. However, prior research demonstrates that psychological assessment tools with weak psychometric properties are routinely admitted in court, rarely challenged on the basis of their reliability, and if a challenge is indeed raised, often still admitted (Neal et al., 2019). Is neuropsychological assessment evidence in particular vulnerable to the same pitfalls? The present research aimed to 1) quantify the quality of neuropsychological assessment evidence used in court, 2) evaluate whether courts are calibrated to the quality of these tools through the rate and success of legal admissibility challenges raised, and 3) compare forensic mental health evaluators’ experiences and practices with regard to the quality of neuropsychological versus non-neuropsychological assessment tools. Neuropsychological tools appeared to perform worse than non-neuropsychological tools in terms of psychometric quality. However, in a case law analysis, significantly fewer challenges were observed to the legal admissibility of neuropsychological tools than to non-neuropsychological tools. To protect the legitimacy of the legal system and prevent wrongful decisions, it is critical that the evidence on which psychologists’ expert opinions are formed is scientifically valid, and that judges and attorneys adequately scrutinize the quality of evidence introduced in court.

Description
Depression has been linked to a significant burden of disease, loss of life, and decreased efficacy of treatment for its comorbidities. Empirical evidence has mounted over the past several decades supporting health benefits from vinegar ingestion, including improvements in blood glucose management, blood cholesterol levels, and inflammation indicators. To date, there have not been any studies in human populations that explore the potential relationship between daily vinegar ingestion and changes in depression indicators and blood metabolomics. This blinded, randomized controlled trial examined the impact of twice-daily vinegar ingestion on mental health measures in healthy young adults recruited from a metropolitan setting. Participants (n=28; aged 25.8±7.0 y; body mass index [BMI] >23 kg/m2) were stratified by age, gender, and BMI and randomly assigned to the liquid (VIN) or pill (CON) groups. VIN participants ingested 2 tablespoons of red wine vinegar (~1550 mg acetic acid; Pompeian Inc., Appendix J) diluted in 8-12 ounces of water, consumed with food at mealtimes twice daily (total ~3100mg acetic acid daily). CON participants consumed 1 vinegar pill daily (22.5 mg acetic acid; Spring Valley, Appendix J). The study lasted four weeks, and anthropometric measurements were conducted in a fasted state at weeks 0 and 4. Study adherence varied slightly (90±17% and 100±14% for VIN and CON respectively, p=0.084); hence, adherence was controlled for in all subsequent analyses. Changes in L-tryptophan (p=0.777, η2=0.003), peripheral serotonin levels (p=0.348, η2=0.035), GABA (p=0.403, η2=0.028), and gut-mediated short-chain fatty acids acetic acid (p=0.355, η2=0.034), and propionic acid (p=0.383, η2=0.031), did not differ significantly between VIN and CON groups respectively with the exception of isobutyric acid (p=0.0374, q=0.0473). However, Patient Health Questionnaire (PHQ-9) depression scores improved significantly for VIN participants in comparison to CON participants (-0.5±1.3 vs. +0.7±2.4 cm [p=0.026] and -0.4±0.7 vs. +0.3±1.0% [p=0.045]. Although these differences between groups are modest, which would be expected given the short study duration, changes were not driven by pharmacological or lifestyle interventions, suggesting the benefits of vinegar ingestion on mental health symptomology and the blood metabolome.

Description
Since the passing of anti-immigration laws, Latinos/as have become more vulnerable to racial profiling, thus increasing the chances of having negative interactions with police officers regardless of documentation status. Within criminology fields it has been reported that Latinos/as in general hold a higher fear towards the police when compared to Whites. However, there is has been limited research capturing perceptions of police officers using a quantitative approach. Method: 26 items were developed and was hypothesized to have 3 subscales: Fear of Police Officers, Anxiety of Interacting with Police Officers, and Self-Perceptions of How Police View Latinos/as. The final analytic sample included 288 self-identified as Latinos/as using an online survey. Most of the participants (92.7%) indicated being either U.S. citizens or permanent residents. Results: Results indicated that there were 3 latent factor structure of the POPS with Cronbach’s alpha’s above 0.9. Results from the Pearson bivariate analysis indicated that POPS sub-scale Anxiety of Interacting of police officers positively correlated with anxiety symptoms (r = .47, p < .01). In addition, POPS sub-scale Fear of Police Officers positively correlated with anxiety symptoms (r = .43, p < .01). POPS sub-scale Perceptions of Police Officers (r = .36, p < .01). Furthermore, direct negative past experiences with police officers had a moderation effect between the associations of self-perceptions of how police view Latinos/as and psychological distress by enhancing the relationship between those two variables (ΔR2= .25, F (2, 297) = 31.82, p < .05; (β = -.16, p > .05). Conclusion: This study contributes to our knowledge on self-perceptions of police among ethnic minorities and its association with mental health. These findings warrant attention for law enforcement and health service providers as it can help assist in understanding the mechanism involved in the development of Latino/a mental health disparities.

Description
Mood disorders are highly prevalent, especially in adolescent populations. One potential cause of the widespread nature of these disorders is the formation of stigma around emotionality. Emotion research, while extensive, has not expanded to capture how a parent’s emotion regulation and expression may lead to stigmatized behaviors in their child affecting that child’s mental health into adulthood. The current thesis aimed to investigate the relevance of this novel concept – emotionality stigma – in the relationship between parental emotionality and adult-child mental health. Using social learning theory, parental emotionality was predicted to influence a child’s emotionality into adulthood. Specifically, this thesis investigated if parental emotion over- and under-expression (dysregulation) would influence adult-children to perceive a stigma around emotionality leading to worse mental health, whereas well-regulated parental emotion expression would relate to adult-child emotional intelligence, leading to better mental health. Moreover, it was predicted that these relationships would differ depending on parent and child gender. To examine these ideas, data was collected from 1,136 college and community individuals through a university survey system and Amazon’s Mechanical Turk. Using a combination of linear regression, PROCESS, and Structural Equation Modeling (SEM) models, the results supported the proposed hypotheses. As predicted, parental dysregulation in childhood predicted impaired adult-child mental health, whereas parental regulation in childhood predicted lower levels of adult-child depression and anxiety. Additionally, emotionality stigma and emotional intelligence partially mediated the relationship between parental emotionality and adult-child mental health. Furthermore, results showed interesting gender differences; male participants were more impacted by both maternal and paternal emotionality as compared to female participants. These findings not only build on emotion research, but also have numerous applications in practice including improving parenting classes and family therapy interventions. This study is the first to explore the role of parental emotionality on adult-child mental health through stigma and emotional intelligence.

Description
Sociopolitical involvement has been previously shown to be associated with experiences of discrimination. Lesbian, gay, and bisexual (LGB) racial/ethnic minorities have faced multiple levels of discrimination from the mainstream community, racial/ethnic minority communities, and LGB communities. However, not many studies have investigated the association between intersectional forms of discrimination and sociopolitical involvement. The present study examines differences in perceptions of racism in the LGB community, sociopolitical involvement in racial/ethnic communities, and sociopolitical involvement in LGB communities among LGB racial/ethnic minorities (N = 203, MAge = 27.25). The sample included 107 (52.7%) men and 96 (47.3%) women; 41 (20.2%) lesbians, 89 (43.8%) gay men, and 73 (36.0%) bisexuals; 47 (23.2%) African Americans, 50 (24.6%) Asian Americans, 64 (31.5%) Latinos/as, and 42 (20.7%) from another race/ethnicity or mixed race. This study also looks at the association between perceptions of racism in the LGB community and sociopolitical involvement in racial/ethnic communities and/or LGB communities. Asian American participants reported perceiving higher levels of racism in the LGB community than Latino/a participants. No other differences in perceptions of racism in the LGB community were found between sexual orientation or by racial/ethnic group. No differences between racial/ethnic group or sexual orientations were found in sociopolitical involvement in racial/ethnic or LGB communities. When controlling for sexual orientation, gender, and race/ethnicity, perceptions of racism in the LGB community predicted sociopolitical involvement in racial/ethnic and LGB communities. By exploring correlates of discrimination from an intersectional perspective, this study provides a better understanding of the experiences of LGB racial/ethnic minorities.

Description
Proponents of cues-filtered-out approaches to communication suggest that the quality of person-to-person interaction is diminished when that interaction is mediated by technology. This postulation has implications for communication given the surging popularity of text messaging in the United States. It is important to examine the degree to which text messaging may inhibit successful communication due to the detriments of technologically mediated communication. The relation between text messaging and romantic relationship satisfaction in individuals ages 18-45 was investigated because successful communication is widely known by researchers and lay individuals to be an integral aspect of healthy intimate relationships. The Relationship Assessment Scale (RAS) (Hendricks, 1988) and an inventory of text messaging behavior was administered to graduate students (n = 22), undergraduate students (n = 24), and people not affiliated with universities (n = 104). Using responses on these inventories, whether or not (1) frequency of text messaging and (2) preference for a particular method of communication are related to romantic relationship satisfaction were evaluated. It was hypothesized that (1) a higher frequency of text messaging will be inversely related with romantic relationship satisfaction and (2) that a participant indicating a preference for verbal phone communication over text messaging communication will be positively correlated with romantic relationship satisfaction. The lack of statistically significant results prevented the drawing of conclusions about relationships between text messaging frequency or preference for voice communication over texting and romantic relationship satisfaction.

Description
Depressive disorders are common among the general populations but are present at an even higher rate among college students. Some research suggests that new stressors during the transition to college may place young adults at increased risk of depressive disorders. In addition, depression in college students has been linked to a variety of risky behaviors such as alcohol use and risky sexual activity. Fortunately, research suggests that religiosity may act as a buffer and lead to lower levels of depressive symptoms and risky behavior. Current research has not adequately examined the relationship between religiosity, depression, and risky behavior among college students. In this study, depressive symptoms were measured using the 20-item Center for Epidemiological Studies Depression scale, while risky behaviors were measured using the section on risky sexual behavior from the Youth Risk Behavior Surveillance survey and the section on alcohol consumption from the Behavioral Risk Factor Surveillance System survey, both developed by the Centers for Disease Control and Prevention. Four questions frequently used in literature to measure critical behaviors and attitudes were used to assess participants' religiosity. It was predicted that engagement in risky behaviors would be associated with higher levels of depressive symptoms while increased religiosity would be associated with lower levels. Additionally, increased religiosity would be associated with lower levels of engagement in risky behavior. Multiple regression analyses revealed that risky behavior were not significantly associated with higher depressive symptoms, while higher church attendance was associated with lower depressive symptoms. Although not considered a risky behavior, ever being forced to have sex was associated with higher depressive symptoms. Linear regression analyses revealed that increased religiosity was associated with increased engagement in risky behavior. These findings suggest that while depressive symptoms and risky behaviors are prevalent among college students, religiosity may act as a buffer and lead to lower levels of depression and risky behavior. Limitations, implications, and future research are discussed.
