Description
Alcohol use disorder (AUD) causes immense global burden and has a significant impact on economic and societal functioning. Efficacious treatments for AUDs have been well-established within the literature, however the most commonly accessed treatments for AUD are alcohol-related services, such as self-help groups, outpatient clinics, and detoxification centers. Though studies suggest these services are effective at treating AUDs, there are numerous differences between individuals who receive alcohol-related services and individuals who do not, causing selection bias. Furthermore, current studies of alcohol-related services frequently define recovery outcomes as abstinence, which reduces variability in viable recovery outcomes, such as reduction of drinking behaviors. In addition, reduction in drinking and alcohol-related problems should theoretically have an impact on broader aspects of functioning, such as familial functioning. Improved familial context may reduce risk to family members, who are otherwise at heightened risk for emotional and behavioral problems when living with a family member with AUD. The current study investigated the effect of alcohol-related services on binary and continuous drinking outcomes after eliminating selection bias using multiple propensity score approaches, to identify the best methodology for a high-risk community sample of individuals with AUD. Propensity scores were created using logistic regression approaches and boosted regression trees. Matching, weighting, and subclassification were used, and matching was performed both using greedy and global approaches. Results suggested subclassification was the most successful method for real world alcohol-related services samples with moderate sample size. Moreover, findings demonstrated that boosted regression approaches were less successful than logistic regression approaches at minimizing the effects of selection bias on known confounding variables that are highly related to group selection. In addition, after removing the effects of selection bias, there were no significant difference between participants who received alcohol-related services and the comparison control group on drinking or family functioning, though both groups reduced drinking from pre- to post-alcohol-related services receipt. Findings suggest careful selection of quasi-experimental methods is warranted in real-world samples, to ensure optimal removal of selection bias. Moreover, future studies should continue to clarify the profile of individual that benefits from alcohol-related services to inform intervention efforts.

Description
Activity in the sympathetic branch of the autonomic nervous system tends tocovary amongst romantic partners. Studies of interpersonal physiology suggest that
romantic partners possess the ability to influence each other’s physiological states, which
may be observable through systematic covariation in partners’ physiological activity (i.e.,
physiological synchrony). However, very few studies have directly tested physiological
synchrony across conversation contexts, which is a notable gap in the literature given that
social context may modulate the implications of physiological synchrony on relational
functioning. Using electrodermal skin conductance as a measure of autonomic activity,
this study used multilevel vector autoregressive modeling to test for time-lagged
physiological synchrony across different-gender romantic partners while they discuss 1) a
mutual stress and 2) a topic of mutual enjoyment. Strong carryover (i.e., autoregressive)
effects were observed in both female and male partners in both conversations.
Unidirectional time-lagged synchrony was observed in the mutual stress conversation,
with female skin conductance preceding and predicting male skin conductance, on
average. No time-lagged synchrony effects were observed in the enjoyment conversation,
on average. Across both conversations, physiological synchrony varied greatly between
each couple. Findings prompt future studies to further explore physiological synchrony
using multiple physiological indicators to identity couple-specific dynamics.

Description
As any group-work member can attest, conveying information, and confirming understanding among group members can be a challenging first step in problem-solving. Despite being a ubiquitous strategy employed in many educational and organizational settings, there are collaborations that fall flat while others succeed. Recent strides have been made in the psycholinguistic approach to communication, evaluating the extent to which speakers align across lexical, syntactic, and semantic usages of language within various task environments, but gaps remain in understanding the role of language in open-ended, emergent problem-solving spaces. Study 1 examines the specific trends and functions of lexical, syntactic, and semantic alignment among speakers in a complex, creative problem-solving effort. As collaborators work through their tasks, lexical alignment decreases as semantic alignment increases and syntactic re-use decreases. These findings suggest alignment may be a sensitive mechanism that hinges on time spent in a collaborative environment and the influencing factor of goal type. More research is needed to understand the varying mechanisms across unique problem-solving spaces that vary in complexity, silence of referents, and cognitive load placed upon performers. Follow-up analyses explore how speakers use specific terms in their collaborative dialogues, assessing the roles of cognition- and action-related language. The use of thinking words (e.g. “think”, “wonder”) predicts when participants may hit an impasse in their collaborations. One interpretation suggests that cognition-related language tends to be involved when groups struggle to convey ideas. Findings from the current work have implications for interventions in organizational and educational domains, along with potential artificial intelligence applications.

Description
With the rise of Posttraumatic Stress Disorder (PTSD) among adults in the United States, understanding the processes of trauma, trauma related disorders, and the long-term impact of living with them is an area of continued focus for researchers. This is especially a concern in the case of current and former military service members (veterans), whose work activities and deployment cycles place them at an increased risk of exposure to trauma-inducing experiences but who have a low rate of self-referral to healthcare professionals. There is thus an urgent need for developing procedures for early diagnosis and treatment. The present study examines how the tools and findings of the field of linguistics may contribute to the field of trauma research. Previous research has shown that cognition and language production are closely linked. This study focuses on the role of prosody in PTSD and pilots a procedure for the data collection and analysis. Data consist of monologic talk from a sample of student-veterans and analyzed with speech software (Praat) for pauses greater than 250 milliseconds per 100 words. The pause frequency was compared to a PCL-5 score, an assessment used to check for PTSD symptoms and evaluate need for further assessment and possible diagnosis of PTSD. This pilot study found the methods successfully elicited data that could be used to measure and test the research questions. Although the findings of the study were inconclusive due to limitations of the participant pool, it found that the research model proved effect as a model for future linguistic research on trauma.

Description
Relations between two aspects of the parent-child relationship, parent warmth and modeling of emotion expression, and youth internalizing and externalizing problems and maladaptive grief were examined in a longitudinal sample of parentally bereaved youth. Youth expressive suppression was tested as a mediator of these relations and youth age was examined as a moderator. Parentally bereaved youth (N=244) aged 8 to 16 and their parents were assessed at three timepoints. Across 14 months, parent modeling of maladaptive emotion expression was significantly associated with increased parent report of both internalizing and externalizing problems, and youth report of parental warmth was significantly associated with decreased youth report of externalizing problems. There was no support for youth expressive suppression mediating these relations and the pattern of relations did not differ significantly by youth age. Implications for intervention programs targeting parents and youth are discussed.

Description
Whether through scaring incarcerated people straight or encouraging rehabilitation through treatment, most people hope that, one way or another, incarceration will alter an individual’s path towards a better life. Current forms of incarceration are not achieving this goal and instead inflict undue amounts of pain (Crewe, 2011; Sykes 1958). In times of deprivation and isolation, some people have found ways to not only persevere, but to thrive. Though these individuals are not commonly the focus of criminal justice literature, there is much value in shifting attention to people thriving in prison including the opportunity to gain knowledge on the multi-faceted nature of well-being broadly and the rehabilitation of incarcerated people more specifically. The current study uses structured interview data from 386 men serving time in a medium-security prison unit to explore the correlates of life satisfaction among people in prison. To identify contributing factors to well-being during incarceration, logistic and multinomial regressions analyze variation in the life satisfaction scores of these incarcerated men. The results from these analyses suggest that perceptions of life meaning, generativity, flourishing, and age are all positively associated with thriving in prison and frequency of experiences with incarceration are not related, positively or negatively, to life satisfaction. This study provides some support to current well-being literature and also introduces complexities to the existing knowledge regarding the relationships between demographics such as race or relationship status, and well-being.

Description
Sexual minorities use social media platforms at higher rates than heterosexual individuals, often to find and connect with other sexual minorities and the broader online LGBTQ+ community. These online connections may help normalize feelings and experiences as a sexual minority in a heterosexual-normed society by increasing exposure to more meaningful reference groups and helping to mitigate the negative impact of heterosexist norms. There has been relatively little research investigating online social connectedness (OSC) among sexual minority adults, the relation between OSC and positive psychological outcomes, and the role of OSC in lessening the impact of heterosexist norms. The goal of the present thesis was to examine the relation between OSC and positive psychological outcomes, and whether such a relation is mediated by compulsory heterosexuality (CH; i.e., heterosexist norms) and internalized heterosexism (IH; i.e., internalizing and accepting heterosexist norms). A sample of 298 sexual minority adults in the U.S. completed an online survey that included measures of OSC, CH, IH, and positive psychological outcomes including resilience, well-being, self-acceptance, and self-esteem. The hypothesized model, with CH and IH as serial mediators of the relation between OSC and positive psychological outcomes, along with a series of alternative models, were tested using structural equation modeling. Support was found for the hypothesized model, such that greater OSC predicted lower CH, which then predicted lower IH, which in turn predicted greater positive psychological outcomes. While several alternative models had adequate fit, the hypothesized model was best supported statistically and by previous literature. These findings provide insights into the psychological benefits of social media connections for sexual minorities and the potential for OSC to lessen the impact of heterosexist norms. This study also adds to the existing literature regarding OSC and sexual minority adults, expanding the literature from primarily focusing on sexual minority youth. Future studies should be more socio-demographically diverse and longitudinal in nature in order to help better understand the directionality of the relationship between CH and IH. The present findings may also inform the development of interventions aimed at decreasing CH and IH, which future studies should investigate more fully.

Description
The current study explores the extent to which different processing strategies affect comprehension accuracy and integration of information across multiple texts. Reading comprehension of single texts is a difficult task, in which the challenges are compounded by the need to integrate information across texts. Processing strategies, such as self-explanation and source-evaluation, help reduce the challenges that readers face when attempting to comprehend texts. Self-explanation has been a successful strategy for coherence-building processes in single text comprehension, but the benefits for supporting inter-textual comprehension have not yet been explored. Source-evaluation supports identification of different sources, which helps resolve inconsistencies between texts; yet it remains unclear whether sourcing alone supports comprehension within as well as between texts. Think-aloud is a strategy intended to encourage further processing of the text without providing any explicit comprehension strategy. The differences between these two strategies prompts questions regarding the adequacy of either strategy for supporting inferencing and integration within and across texts. In this study, participants (n=80) were randomly assigned to one of three strategy conditions: self-explanation, source-evaluation, or think-aloud. Students read four texts after which they completed three types of open-ended comprehension questions (i.e., textbase, intra-textual inference, and inter-textual inference), a source memory task, and individual difference measures. Prior knowledge and reading skill were strongly correlated (r = .65) and showed moderate correlations (r = .31 to .60) with participants’ comprehension accuracy, total number of integrations within their responses, and their memory for sources. Participants were more likely to respond accurately and demonstrate integrations across texts for the text-based questions in comparison to the more challenging inference questions. There was a marginal effect of condition on comprehension question accuracy, wherein participants who self-explained responded more accurately than those who engaged in the think-aloud task. In addition, those in the self-explanation or source-evaluation conditions recalled more sources than those in the think-aloud condition. There were no significant differences in performance between the self-explanation and the source-evaluation conditions. Overall, the results of this study indicate that encouraging students to self-explain and/or evaluate sources while they read multiple documents enhances comprehension and memory for sources.

Description
The purpose of this research was to investigate the effect of the type of crime (namely, its perceived immorality) a juvenile is suspected of on how juvenile suspects are perceived (in terms of moral character, immaturity, and suggestibility) and, in turn, interrogated. I expected act-person dissociation to influence that effect. To that end, perceptions of crime (i.e., immorality, seriousness) were also investigated. The study was first conducted with law enforcement officers (n = 55), then replicated with laypeople (n = 171). Participants were randomly assigned to one of three crime conditions: robbery, sexual assault, and murder. In each condition, participants read a probable cause statement involving a 15-year-old suspect. There were several key findings: (1) Murder was the most serious crime, whereas robbery and sexual assault were more immoral. (2) Act-person dissociation did not occur. (3) Participants were more likely to endorse the use of psychologically coercive tactics on the juvenile suspected of sexual assault than the juvenile suspected of murder. (4) The more favorably participants perceived a juvenile’s moral character, the less likely they were to endorse the use of psychologically coercive interrogation tactics. (4) Participants who more strongly agreed that juveniles are more immature and suggestible than adults were less likely to endorse the use of psychologically coercive tactics, more likely to endorse the use of tactics that encourage compliance with interrogators, and more likely to adhere to the PEACE model of juvenile interrogations. The implications and limitations of these findings are discussed, along with potential directions for future research.

Description
Ecological systems theory argues that multiple nested systems impact child development. This study used a moderated mediation pathway to examine whether presence of a grocery store, number of fast-food restaurants, outdoor play space, and outdoor play safety affected children’s blood pressure and BMI through variation in healthy family habits. Maternal perceived neighborhood social and cultural cohesion was examined as a moderator of the mediated effect. Data was collected from 214 mother–child dyads via biological measurement, maternal-report surveys, and geocoding of children’s neighborhoods using Google Earth. Zero-order correlations showed that higher number of fast-food restaurants in a child’s neighborhood was correlated with less engagement in healthy family habits and lower child BMI z-score. In all models, higher neighborhood social and cultural cohesion was associated with more engagement in healthy family habits. No statistically significant mediated effects or moderation of the mediated effects were found. Future directions may aim to identify which objective neighborhood environment indicators influence child health and what are potential variables mediating the relation.
