Previous work has attempted to fit reward-driven attentional selection as being exogenous (stimulus-driven) or endogenous (goal-driven). However, recent work suggests that reward’s effects on attention depend on the type of stimulus feature that the motivational information is imparted during learning (incentive salience). If true, then reward should not be limited to solely impacting early perceptual or late categorization processes attention. The current study used event-related potentials (ERPs) to test the idea that reward’s effects on attention depend on the process that the reward information is embedded – early perceptual or late categorization. Results demonstrated reward-driven effects on perceptual representation when value information was conveyed by cues in a spatial cuing task, but did not find any value-driven effects when value was introduced later in processing in target-defined features in a target detection task. The current work suggests that reward can be rapidly acquired and sustained throughout a task, recruiting mechanisms of both exogenous and endogenous attention.

This paper aims to study the factors relating to eating disorders and disordered eating onset. Adolescents are the focus on this review and through the evaluation of these factors. Individual factors being addressed are as follows: active social media use, experience of child abuse or maltreatment, and chronic illnesses. Evaluating family factors such as family history, experience of intimate partner violence, and parenting dynamics allow us to understand the environment and its effect on eating disorder onset. Finally, protective factors addressed include parental resilience, concrete support, and emotional competence. Understanding the associations between these factors and disordered eating will aid in better treating and preventing eating disorders in adolescents.

Spirituality represents a key part of life for the majority of U.S. adults and there is a growing body of research supporting relationships between spirituality and numerous health outcomes. Governing healthcare organizations have acknowledged the role religiousness and spirituality play in comprehensive and holistic patient care. While the U.S. shows documented trends towards diverse expressions of spirituality, existing theory-driven measures of spirituality are largely theocentric. The current study concludes a multiphase project that aimed at the outset to develop an inclusive measure of spirituality and establish initial psychometric evidence, validating its use across both theistic and nontheistic spiritual populations. The Inclusive Spiritual Connection Scale (ISCS) was developed based on an expanded conceptualization of spiritual connection to include both theistic and nontheistic expressions of spirituality. The current study builds on a previous study that established preliminary evidence of content validity of the ISCS, from which a 45-item pool was developed. In the present study, data were collected from 736 participants who indicated either theistic or nontheistic sources of spiritual connection. Using a split sample approach (primary developmental sample, n = 368; secondary developmental sample, n = 368) and a test-retest subsample (n =129), the 45-item pool underwent three phases of data analysis to establish initial psychometric evidence of the ISCS for use with theistic and nontheistic populations. Through a series of factor analytic procedures, the 45-item pool was reduced to 13 items, yielding a unidimensional scale of spiritual connection with evidence of sound psychometric properties. The ISCS demonstrated adequate evidence of convergent validity, limited evidence of divergent validity, and strong evidence of reliability. Assessment of measurement equivalence across nontheistic and theistic groups yielded partial evidence of equivalence; however, the baseline levels of spiritual connection appeared to differ between theistic and nontheistic participants. Initial psychometric properties support the ISCS as a reliable and valid tool to assess spiritual connection in spiritually diverse populations, though comparison between spiritual groups requires further validation. The ISCS responds directly to existing gaps in research and possesses the ability to support holistic healthcare care for all US adults regardless of spiritual expression.

Forgiveness is the act of moving beyond shame, guilt, anger, or blame, and it has been linked to psychological well-being, prosocial behavior, and religion/spirituality (R/S). However, the research on why and how people forgive is inconsistent, as the concepts involved are complex and difficult to define and operationalize. The purpose of this interpretative phenomenological analysis (IPA) was to provide a better understanding of why and how people are cognitively and emotionally able to forgive and the role of R/S in that process. Goal orientation and cognitive restructuring theories were used as frameworks for understanding the forgiveness experience. First-person, semistructured interviews were conducted with 12 persons from 10 different sacred belief systems who had experienced forgiveness of a major transgression. Data were analyzed using the IPA process, and five themes emerged: what is forgiveness?; why forgive?; how to forgive; the relationship between self-forgiveness and forgiveness of others; and developing a forgiveness disposition. All participants described forgiveness as an effortful, transformative process. Their motivation to forgive was based on a learning goal orientation and benefits to personal well-being and relationships. Participants forgave through making supportive R/S and/or social connections, finding the courage to confront transgressions, and resolving issues with compassion and creativity. A model of forgiveness was proposed that researchers can apply to future research efforts, and that mental health providers, clergy, and other helping professionals can use with clients in therapeutic applications of healing from major transgressions.

Body objectification theories propose that humans have an innate desire to compare themselves with others. When self-objectification is influenced by media exposure to idealized body images, results may be unrealistic self-perceptions and increased risk of depression, eating pathology, and overexercising. Although considerable work has been done to study these processes among women, much less is known about effects of media exposure on adult men. In response to this gap, this quantitative research study examined effects of exposure to an idealized man's body image on men observers' body dissatisfaction and related behaviors. A convenience sample of 119 freshman and sophomore community college men ranging in ages 18 to 29 was assigned to 1 of 2 conditions where they were exposed to images of male models with idealized bodies or to a neutral landscape image (independent variable). They completed questions to assess their body dissatisfaction, drive for muscularity, disordered eating, and depression. BMI and workout frequency also were assessed as covariates. It was predicted that body dissatisfaction, drive for muscularity, disordered eating, and depression scores would be higher for the group exposed to the idealized body images, as compared with neutral images. The research hypotheses were tested using ANCOVA analyses. No statistically significant between-group differences were found for any of the dependent variables. Design limitations and suggestions for further research are discussed. This study has social significance as it helps to keep the focus of researchers and mental health providers on media exposure as a risk factor among males for negative body image and related behaviors.

Although significant research has shed light on what happens to children when they are removed from their parents, few studies have explored the effects on parents undergoing separation from their children. Discussions tend to be confined to separate dimensions exploring child’s needs on one side and parental obligations on the other. Much of the planning and prolonged care provided for children in placement reflects a traditional child-centered focus. This has led to a lack of attention to parental needs, and a gross ignorance about their lives, feelings and aspirations. When women are involuntarily separated from their children through incarceration, a more complex disruption between parent and child occurs. There is systemic research done on the unique nature and meaning of this separation to mothers. With this in mind, the focus of this descriptive study has been on the exploration of feelings and attitudes of imprisoned mothers regarding enforced separation from their children and the effects of imprisonment on their maternal role.

To understand the impact of daily travel on personal and societal well-being, researchers are developing measurement techniques that go beyond satisfaction-based measures of travel. Metrics related Subjective Well-Being (SWB), defined as an evaluation of one's happiness or life satisfaction, are increasingly important for evaluating transportation and land-use policies. This dissertation examines commute well-being, a multi-item measure of how one feels about the commute to work, and how it is shaped. Data are from a web-based survey of workers (n=828) in Portland, Oregon, U.S.A., with three roughly equally sized groups based on mode: bike, transit and car users. Descriptive analysis shows that commute well-being varies widely across the sample. Those who bike and walk to work have significantly higher commute well-being than transit and car commuters. A multiple linear regression model shows that along with travel mode, traffic congestion, travel time, income, health, attitudes about travel, job satisfaction and residential satisfaction also play important individual roles in shaping commute well-being. A structural equation model reveals a significant correlation between commute well-being and overall happiness, controlling for other key happiness indicators. This research helps expand existing theory by demonstrating (1) how commute well-being can be measured and modeled; (2) how accessibility, distance and travel time impact commute well-being; (3) how individual mode choices interact with attitudes to impact commute satisfaction and (4) commuting's relationship to overall well being.

<p> </p> <p>Though literature on the influence and efficacy of service dogs as a complementary and integrative health intervention option for a variety of needs (e.g., medical, mobility, psychiatric) continues to emerge, a focus on how service dogs are integrated into the everyday lives of their handlers remains understudied. This dissertation offers new insights to this previously understudied area by first comparing the expectations versus lived experiences of veteran service dog handlers with posttraumatic stress disorder (PTSD) and then focusing in on the influence of service dogs beyond the handler, looking at the influence of service dogs on spouses, family members and caregivers. Using a rigorous multi-modal approach, both qualitative and quantitative insights emerge regarding the integration of a service dog for the handler and their families. Findings suggest that understanding the similarities and differences between expectations and experiences may help to inform practitioners and interested recipients about the service dog intervention and help to set realistic expectations about the integration process. Additionally, in populations of psychiatric assistance dogs for posttraumatic stress disorder (PTSD) and in populations of mobility and medical alert assistance dogs, findings suggest that the benefits and challenges of the intervention reach beyond the service dog recipient and handler, extending to affect the wellbeing of their families and caregivers. Researchers and practitioners should work together to develop programs that integrate these findings to provide family-focused educational interventions where both positive and negative experiences are shared alongside strategies to overcome the challenges associated with integrating a service dog into a home prior to pairing. Providing this opportunity enables setting realistic expectations for this complementary and integrative intervention option which in turn may affect its efficacy and success throughout and beyond the integration process. </p>

This investigation was an analysis of the effects of methylphenidate (MPH; trade name: Ritalin) on drug reward using the conditioned place preference (CPP) behavioral paradigm in a rodent model and underlying mechanisms of this effect. Animals were conditioned in adolescence from postnatal day (P)33-39) or P44-49 with saline, 1 or 5 mg/kg MPH. Rats administered 5 mg/kg but not 1 mg/kg MPH, resulted in a significant preference that was more robust in younger male adolescent rats. The 5 mg/kg dose of MPH also resulted in a significant decrease of the dopamine transporter in both the nucleus accumbens and striatum, revealing dopamine clearance is decreased by MPH in brain areas that mediate reward. Finally, MPH-induced CPP was blocked by the dopamine D1 but not D2 antagonist, demonstrating the importance of the D1 receptor in the rewarding effects of MPH. These results demonstrate that dopamine mediates the rewarding effects of MPH in adolescence.

Self-control has been measured using a variety of methods including self-report measures, cognitive inhibition tasks, delay discounting and delay of gratification tasks, and persistence and willpower tasks. Although these are all theoretically linked to processes involved in self-control, recent evidence has shown that these diverse measurement techniques relate only minimally to one another. Assuming that self-control is a reflective construct, this would indicate that many of these tasks are poor indicators of self-control. The present research challenges the common assumption that self-control is a reflective construct and instead proposes that self-control is a formative construct. Conceptualizing self-control as a formative construct could reconcile some of the inconsistencies in the literature, in particular the fact that many indicators for self-control do not correlate highly. To examine the possibility of a formative model of self-control, this research examines 13 commonly used measures of self-control and investigates indicator intercorrelations, indicator relationships with the theoretical consequences of self-control, and performs a vanishing tetrad test (Bollen & Ting, 2000). Results show that in general, indicator intercorrelations are low and nonsignificant as well as indictor correlations with theorized construct consequences. The results of the vanishing tetrad test suggest a reflective interpretation of self-control, but concerns with uniformly low covariances between indicators limit the interpretation of this test.
