Description
This dissertation explores the role of smart home service provisions (SHSP) as motivational agents supporting goal attainment and human flourishing. Evoking human flourishing as a lens for interaction encapsulates issues of wellbeing, adaptation and problem solving within the context of social interaction. To investigate this line of research a new, motivation-sensitive approach to design was implemented. This approach combined psychometric analysis from motivational psychology's Personal Project Analysis (PPA) and Place Attachment theory's Sense of Place (SoP) analysis to produce project-centered motivational models for environmental congruence. Regression analysis of surveys collected from 150 (n = 150) young adults about their homes revealed PPA motivational dimensions had significant main affects on all three SoP factors. Model one indicated PPA dimensions Fearful and Value Congruency predicted the SoP factor Place Attachment (p = 0.012). Model two indicated the PPA factor Positive Affect and PPA dimensions Value Congruency, Self Identity and Autonomy predicted Place Identity (p = .0003). Model three indicated PPA dimensions Difficulty and Likelihood of Success predicted the SoP factor Place Dependency. The relationships between motivational PPA dimensions and SoP demonstrated in these models informed creation of a set of motivational design heuristics. These heuristics guided 20 participants (n = 20) through co-design of paper prototypes of SHSPs supporting goal attainment and human flourishing. Normative analysis of these paper prototypes fashioned a design framework consisting of the use cases "make with me", "keep me on task" and "improve myself"; the four design principles "time and timing", "guidance and accountability", "project ambiguity" and "positivity mechanisms"; and the seven interaction models "structuring time", "prompt user", "gather resources", "consume content", "create content", "restrict and/or restore access to content" and "share content". This design framework described and evaluated three technology probes installed in the homes of three participants (n = 3) for field-testing over the course of one week. A priori and post priori samples of psychometric measures were inconclusive in determining if SHSP motivated goal attainment or increased environmental congruency between young adults and their homes.

Description
Fibromyalgia (FM) is a chronic musculoskeletal disorder characterized by widespread pain, fatigue, and a variety of other comorbid physiological and psychological characteristics, including a deficit of positive affect. Recently, the focus of research on the pathophysiology of FM has considered the role of a number of genomic variants. In the current manuscript, case-control analyses did not support the hypothesis that FM patients would differ from other chronic pain groups in catechol-O-methyltransferase (COMT) and mu-opioid receptor (OPRM1) genotype. However, evidence is provided in support of the hypothesis that functional single nucleotide polymorphisms on the COMT and OPRM1 genes would be associated with risk and resilience, respectively, in a dual processing model of pain-related positive affective regulation in FM. Forty-six female patients with a physician-confirmed diagnosis of FM completed an electronic diary that included once-daily assessments of positive affect and soft tissue pain. Multilevel modeling yielded a significant gene X environment interaction, such that individuals with met/met genotype on COMT experienced a greater decline in positive affect as daily pain increased than did either val/met or val/val individuals. A gene X environment interaction for OPRM1 also emerged, indicating that individuals with at least one asp allele were more resilient to elevations in daily pain than those homozygous for the asn allele. In sum, the findings offer researchers ample reason to further investigate the contribution of the catecholamine and opioid systems, and their associated genomic variants, to the still poorly understood experience of FM.

Description
In rehabilitation settings, activity limitation can be a significant barrier to recovery. This study sought to examine the effects of state and trait level benefit finding, positive affect, and catastrophizing on activity limitation among individuals with a physician-confirmed diagnosis of either Osteoarthritis (OA), Fibromyalgia (FM), or a dual diagnosis of OA/FM. Participants (106 OA, 53 FM, and 101 OA/FM) who had no diagnosed autoimmune disorder, a pain rating above 20 on a 0-100 scale, and no involvement in litigation regarding their condition were recruited in the Phoenix metropolitan area for inclusion in the current study. After initial questionnaires were completed, participants were trained to complete daily diaries on a laptop computer and instructed to do so a half an hour before bed each night for 30 days. In each diary, participants rated their average daily pain, benefit finding, positive affect, catastrophizing, and activity limitation. A single item, "I thought about some of the good things that have come from living with my pain" was used to examine the broader construct of benefit finding. It was hypothesized that state and trait level benefit finding would have a direct relation with activity limitation and a partially mediated relationship, through positive affect. Multilevel modeling with SAS PROC MIXED revealed that benefit finding was not directly related to activity limitation. Increases in benefit finding were associated, however, with decreases in activity limitation through a significant mediated relationship with positive affect. Individuals who benefit find had a higher level of positive affect which was associated with decreased activity limitation. A suppression effect involving pain and benefit finding at the trait level was also found. Pain appeared to increase the predictive validity of the relation of benefit finding to activity limitation. These findings have important implications for rehabilitation psychologists and should embolden clinicians to encourage patients to increase positive affect by employing active approach-oriented coping strategies like benefit finding to reduce activity limitation.

Description
Artists and designers are preparing for rapidly changing and competitive careers in creative fields that require a healthy dose of resiliency to persevere. However, little is known on how students within these fields become more self-efficacious, gritty, situated toward a growth mindset, and persistent over time. This mixed-method action research study investigates how undergraduate arts and design college students approach and navigate perceptions of failure as well as incorporates an intervention course designed to increase their self-efficacy, growth mindset, and academic persistence. Participants were eighteen arts and design students representing a variety of disciplines from an eight-week, one-unit, 300-level course that utilized arts-based methods, mindfulness, and active reflection. After the course, students had significant changes in their self-efficacy and academic persistence as well as moderate significant change in their fixed mindset.

Description
Eat Your Heart Out is a visually rich qualitative ethnic food research that examines consumption, production, and distribution practices transnationally. Through the example of Mumbai’s street foods, the study aims to discover how design participates in fashioning the street food experiences locally and globally.
Food is an important cultural artifact in the world. However, past research in design suggests that the discipline has mainly focused on food as a catalyst for creativity and imagination or as a tool to examine materialistic, economical, sensorial, and emotional connections. Studying the user-focused involvement in the creation of food artifacts and focusing on cultural, global, and historical aspects of that participation are important to address the gaps in the knowledge required to solve increasingly “wicked problems” (Buchanan, 1992; Rittel, 1971). To achieve this goal, Eat Your Heart Out implemented a comparative practice-based study of the Indian street foods in Mumbai and Phoenix to examine consumption, production, and distribution practices at both places. The methodological design was highly multi-disciplinary in nature and included rapid ethnographic assessment, interviews, visual research, and a generative method of co-creation.
The study revealed that street foods as cultural artifacts were deeply rooted in specific traditional values specific to the context, which significantly influenced personal and communal consumption, production, and distribution practices of Indian street foods in Mumbai and Phoenix. The values of standardization, formality, and higher food regulation practices limited the diversity and radically transformed the central values of Mumbai’s street foods when the foods re-territorialized in Phoenix. This resulted in lowering the consumption.
Eat Your Heart Out presents cultural and practical insights into the interactions between contexts, artifacts, practices, and participants. Eat Your Heart Out recommends new frameworks of correlation for various consumption and production practices and suggests how street food artifacts alter when they move across cultures. Such knowledge can be valuable for similar ethnic food culture studies and the development of innovative research tools incorporating transnational and multidisciplinary methods in the future.
On a broader scope, Eat Your Heart Out provides a unique opportunity to study a culture that has not been examined by scholars much in the past. It also focuses on gaining knowledge about ethnic culinary practices of Indian immigrants in the United States and encouraging enhanced cross-cultural acceptance.

Description
The present study utilized longitudinal data from a high-risk community sample (n= 377; 166 trauma-exposed; 54% males; 52% children of alcoholics; 73% non-Hispanic/Latino Caucasian; 22% Hispanic/Latino; 5% other ethnicity) to test a series of hypotheses that may help explain the risk pathways that link traumatic stress, posttraumatic stress disorder (PTSD) symptomatology, and problematic alcohol and drug use. Specifically, this study examined whether pre-trauma substance use problems increase risk for trauma exposure (the high-risk hypothesis) or PTSD symptoms (the susceptibility hypothesis), whether PTSD symptoms increase risk for later alcohol/drug problems (the self-medication hypothesis), and whether the association between PTSD symptoms and alcohol/drug problems is due to shared risk factors (the shared vulnerability hypothesis). This study also examined the roles of gender and ethnicity in these pathways. A series of logistic and negative binomial regressions were performed in a path analysis framework. A composite pre-trauma family adversity variable was formed from measures of family conflict, family life stress, parental alcoholism, and other parent psychopathology. Results provided the strongest support for the self-medication hypothesis, such that PTSD symptoms predicted higher levels of later alcohol and drug problems among non-Hispanic/Latino Caucasian participants, over and above the influences of pre-trauma family adversity, pre-trauma substance use problems, trauma exposure, and demographic variables. Results partially supported the high-risk hypothesis, such that adolescent substance use problems had a marginally significant unique effect on risk for assaultive violence exposure but not on overall risk for trauma exposure. There was no support for the susceptibility hypothesis, as pre-trauma adolescent substance use problems did not significantly influence risk for PTSD diagnosis/symptoms over and above the influence of pre-trauma family adversity. Finally, there was little support for the shared vulnerability hypothesis. Neither trauma exposure nor preexisting family adversity accounted for the link between PTSD symptoms and later substance use problems. These results add to a growing body of literature in support of the self-medication hypothesis. Findings extend previous research by showing that PTSD symptoms may influence the development of alcohol and drug problems over and above the influence of trauma exposure itself, preexisting family risk factors, and baseline levels of substance use.

Description
Pediatric chronic pain is pervasive and associated with myriad adverse consequences, yet due consideration has not been given to the mental health disturbances that often present alongside chronic pain and the etiological mechanisms that potentially underlie both. The current study examined the etiology underlying chronic pain and internalizing symptomology in middle childhood, considering both independent and co-occurring symptom presentations. Phenotypic parent-offspring associations across chronic pain and internalizing symptomology were also examined. Lastly, nuclear twin family models were tested to determine the extent to which genetic and environmental factors underlie parent-offspring transmission. The sample comprised 795 children (399 families; Mage= 9.7 years; SD = 0.92) and their parents drawn from the Arizona Twin Project. Results indicated that chronic pain was highly heritable (78%), whereas internalizing symptomology was modestly heritable (32%) and further subject to moderate shared environmental influence (50%). Moreover, 9% of the variance in chronic pain was explained by additive genetic factors shared with internalizing symptomology. Maternal chronic pain and internalizing symptomology were positively associated with both child chronic pain and internalizing symptomology. The association between maternal chronic pain and child chronic pain was more pronounced for girls than boys, whereas the association between maternal internalizing symptomology and child internalizing symptomology was more pronounced for boys than girls. Paternal chronic pain was not significantly associated with child chronic pain but was unexpectedly associated with lower child internalizing symptomology. The negative association between paternal chronic pain and child internalizing symptomology was more pronounced for boys than girls. Paternal internalizing symptomology was not significantly associated with child chronic pain but was positively associated with child internalizing symptomology. Lastly, the best fitting reduced nuclear twin family models for both chronic pain and internalizing symptomology retained additive genetic, sibling-specific shared environmental, and nonshared environmental parameters, where parent-offspring transmission was solely explained by shared genetics and sibling-specific shared environmental factors further accounted for co-twin resemblance. Results provide novel insight into common liabilities underlying chronic pain and internalizing symptomology in middle childhood, parent-offspring associations across chronic pain and internalizing symptomology, and the etiological mechanisms that explain symptom aggregation across generations.

Description
Guided by the Risky Families model and Daily Process methods, the present study examined how daily stressors are related to emotional well-being at the between- and within-person levels among adolescent grandchildren raised by grandmothers. This study also examined whether risk (i.e., adverse childhood experiences/ACES) and resilience (i.e., socio-emotional skills) factors were linked to differences in daily well-being, stressor exposure, and emotional reactivity, and evaluated the efficacy of an online social intelligence training (SIT) program on daily stressor-emotion dynamics. Data came from a subsample (n = 188) of custodial adolescents who participated in an attention-controlled randomized clinical trial and completed 14-day daily surveys prior to and following intervention. Analyses were conducted with dynamic structural equation modeling. Daily stressors, on average, and experiencing above average stressors, were associated with higher negative emotions and lower positive emotions and social connection. Those with more ACEs, on average, reported higher daily stressors and worse well-being, whereas those with higher socio-emotional skills, on average, reported lower daily stressors and better well-being. At the within-person level, more ACEs were associated with higher daily negative emotions. Nonverbal processing was linked to higher daily positive emotions and social connection. Conversational skills were associated with higher daily positive emotions and social connection, and lower, more inert daily negative emotions. Neither ACEs nor socio-emotional skills were associated with within-person reactivity to stressors. Also, the SIT program did not demonstrate efficacy for any outcome. My discussion focused on how findings extend the literature on custodial adolescents by showing that daily stressors impact well-being, offer knowledge of how ACEs and socio-emotional skills shape daily stressor-emotion dynamics, and considers reasons why the online, self-guided SIT program failed to show efficacy on key outcomes.

Description
Adults with autism spectrum disorder (ASD) face heightened risk of co-occurring psychiatric conditions, especially depression and anxiety disorders, which contribute to seven-fold higher suicide rates than the general population. Mindfulness-based stress reduction (MBSR) is an 8-week meditation intervention centered around training continuous redirection of attention toward present moment experience, and has been shown to improve mental health in autistic adults. However, the underlying therapeutic neural mechanisms and whether behavioral and brain changes are mindfulness-specific have yet to be elucidated. In this randomized clinical trial, I utilized functional magnetic resonance imaging (fMRI) and electroencephalography (EEG) to characterize fMRI functional activity (Study 1) and connectivity (Study 2) and EEG neurophysiological (Study 3) changes between MBSR and a social support/relaxation education (SE) active control group. Study 1 revealed an MBSR-specific increase in the midcingulate cortex fMRI blood oxygen level dependent signal which was associated with reduced depression. Study 2 identified nonspecific intervention improvements in depression, anxiety, and autistic, and MBSR-specific improvements in the mindfulness trait ‘nonjudgment toward experience’ and in the executive functioning domain of working memory. MBSR-specific decreases in insula-thalamus and frontal pole-posterior cingulate functional connectivity was associated with improvements in anxiety, mindfulness traits, and working memory abilities. Both MBSR and SE groups showed decreased amygdala-sensorimotor and frontal pole-insula connectivity which correlated with reduced depression. Study 3 consisted of an EEG spectral power analysis at high-frequency brainwaves associated with default mode network (DMN) activity. Results showed MBSR-specific and nonspecific decreases in beta- and gamma-band power, with effects being generally more robust in the MBSR group; additionally, MBSR-specific decreases in posterior gamma correlated with anxiolytic effects. Collectively, these studies suggest: 1) social support is sufficient for improvements in depression, anxiety, and autistic traits; 2) MBSR provides additional benefits related to mindfulness traits and working memory; and 3) distinct and shared neural mechanisms of mindfulness training in adults with ASD, implicating the salience and default mode networks and high-frequency neurophysiology. Findings bear relevance to the development of personalized medicine approaches for psychiatric co-morbidity in ASD, provide putative targets for neurostimulation research, and warrant replication and extension using advanced multimodal imaging approaches.

Description
Over the past century, the relationship between the built environment and people’s health and well-being has become central to the discussion and critique of healthcare design. The concept of such a relationship is not new; more than a century ago, Florence Nightingale promoted a particular vision for hospital design. Her concerns with naturalism, acoustics, ventilation, and aesthetics in the healthcare environment are as relevant today as they were in the mid-19th century.
This dissertation examines Nightingale’s contributions to the development of the nascent field of healthcare interiors by: identifying major developments of healthcare interiors through the centuries; investigating Nightingale’s life, work, and principles on the healthcare environment; and examining whether certain contemporary hospital design approaches support, expand upon, or negate her principles. The research integrates material culture analysis of extant objects and content analysis of documents within the framework of a case study of two healthcare facilities in Tucson, Arizona.
Findings show that the Nightingale era was seminal in the evolution of the healthcare environment, with key developments towards healthful interiors for the sick. Wide adoption of hospital design guidelines suggested by Nightingale—emphasizing physical elements such as ventilation, natural light, view, sanitization, and ambiance—occurred in various types of healthcare facilities, including military and tuberculosis sanatoria around the world. Additionally, analysis of the case study shows just how welcoming and supportive a 1920s healthcare facility, like the Desert Sanitarium, can be. The facility successfully adapts Florence Nightingale’s principles to the local climate and context, including indigenous pueblo architecture, traditional
Southwestern materials, Native American artifacts, desert views, and even the traditional courtyard plan used by Spanish colonial settlers. This successful adaptation suggests that Nightingale’s principles may be valuable to and relevant within different places and times, even today.
Thus, Nightingale contributed to the emerging field of healthcare interiors by: 1) functionally organizing the built environment affecting patients’ healing, 2) preventing healthcare-associated infection in the physical environment, and 3) supporting psychological health with aesthetic amenities. The findings advance interior design scholarship, education, and practice; and further the documentation and explication of Arizona’s history in the healthcare environment.
