Promoting population health is an essential task for sustainable development. This study explores the association between socioeconomic status and perceived health in the United States, with special attention on the influence of living arrangements. It also improves the existing explanations of causal mechanisms underlying the impact of SES on health among Americans over 50. Using the first and seventh waves of Health and Retirement Study to run ordered logistic regression, this research addresses the importance of living arrangements and social capital on self-reported health. Income and education are both important predictors of self-reported health. In addition, living arrangements and household social capital also affects self-reported health after controlling individuals’ characteristics and SES indicators. These effects do not appear to mediate the socioeconomic effects on self-reported health. Future research should highlight better measures of living arrangements and social capital, as well as explore longitudinal analyses.

Dysfunction of the visual cortex is implicated in psychosis and recently, the extrastriate visual cortex (V5/MT) has been causally linked to visual hallucinations through lesion network mapping. Transcranial electric stimulation (tES) has been shown to improve psychotic symptoms and cognition in psychosis spectrum disorders. However, few investigations have used novel approaches, such as high definition tES (HD-tES) to target specific brain circuits. Previously, we showed that stimulation delivered to V5/MT using HD-tDCS (direct current) reduced Positive and Negative Syndrome Scale (PANSS) general symptoms in the short-term (5 days), while HD-tACS (alternating current) improved general symptoms and functioning in the long-term (30 days). Here, we aim to determine if HD-tES to V5/MT has altering effects on cognition and self-reported symptoms of psychosis, and to investigate the differences between self-reported and clinician-reported symptoms. A pilot open label study with a within-subjects, single blind, crossover design was conducted in order to characterize the efficacy of cathodal HD-tDCS and 2Hz delta HD-tACS for psychosis treatment. Enrolled patients received 20 mins of HD-tES twice daily for 5 consecutive days applied bilaterally to V5/MT with a washout between conditions. Assessments were performed at baseline, day 5, and day 30. HD-tACS treatment was found to improve cognition on Digit Sequencing, Tower of London, Semantic Fluency, and “S” Letter Fluency tasks as measured by brief assessment of cognition in schizophrenia (BACS) as well as symptoms of paranoid ideation and anger/hostility as measured by the symptom checklist 90 (SC-90) 1 month after treatment. HD-tDCS treatment yielded significant improvement on “F” Letter Fluency as measured by BACS and did not yield any significant improvement on SC-90 symptoms. Lastly, correlations between SC-90 and PANSS described a distinct relationship between the two scales and their measures of psychiatric morbidity. Ultimately, delta wave tACS may be able to improve cognition and certain symptoms of psychosis by altering cortico-cortico communication between relevant brain structures. Future large-scale investigations are needed to further solidify these results. / 2026-03-04T00:00:00Z

Elderly Black and Hispanic adults have poorer overall health, higher disability rates, and lower life expectancies than elderly Whites and other racial and ethnic minority group members. There are also sex differences in health, with women more likely to suffer from non-life threatening chronic conditions and men more likely to suffer from acute conditions. Health pathways, or the processes to good or poor health, are shaped by race, SES, and sex. This study focuses on the race and SES literature, framing race and SES inequalities within a cumulative advantage lens. Using Hierarchical Linear Modeling techniques to examine data from the Health and Retirement Survey, this study finds that there are racial differences in health through health problems, health insurance, and health care treatment, and that Black, Hispanic, and other racial and ethnic minority group members have worse self-reported health than Whites in old age. This study also finds evidence of cumulative advantage through friends in the neighborhood, and finds evidence of cumulative disadvantage through health problems and hospital and nursing home treatment. There are also cumulative disadvantages for women, who have more functional limitations in old age than their male counterparts, and these disadvantages grow over time. This study adds support to the race literature, by furthering understandings of race and SES as interconnected but not interchangeable systems of inequality. In lieu of the findings, this study provides implications for future research and ways to reduce racial health disparities in old age. / Ph. D.

Doctor of Philosophy / Department of Hospitality Management / Kevin R. Roberts / Ethnic foods have gained in popularity and have become mainstream in the diet of most Americans. However, researchers have noted that ethnic food, specifically food served in ethnic restaurants, has been associated with foodborne outbreaks. Little has been done using the Social Cognitive Theory to predict food safety behaviors, especially in independent ethnic restaurants. The purpose of this study was to determine whether self-efficacy, self-regulation, outcome expectations, and environmental determinants are predictive of self-reported food safety behaviors in independent ethnic restaurants. Utilizing a thorough literature review and results of five focus group and group interviews, a questionnaire was developed. The questionnaire was translated to Chinese and Spanish and back-translated to English to ensure consistency. After pilot-testing, a multistage random sampling technique was utilized to collect data, targeting a total of 150 food handlers from independent Mexican and Chinese restaurants. A total of 204 food handlers responded, but due to incomplete data or responses from non-food handlers, 201 responses were usable for a response rate of 80.4%. A multiple regression analysis investigated the prediction of food safety behavioral intentions based on the respondents’ self-efficacy, self-regulation, outcome expectations, and environmental determinants and found the model was significant (F = 75.246, p = 0.002). The significant independent variables in the model were self-regulation (β = 0.467, p = 0.001), environmental determinants (β = 0.181, p = 0.011), and outcome expectations (β = 0.152, p = 0.018), which explained about 60.6 % of the variance in food safety behavioral intentions. Self-efficacy was not significant (β = 0.078, p = 0.219). A mediation analysis showed that behavioral intentions are a significant mediator of the relationships between self-efficacy and self-reported food safety behaviors (b = 0.24, CI [0.161, 0.336], self-regulation and self-reported food safety behaviors (b = 0.252, CI [0.155, 0.366]), outcome expectations and self-reported food safety behaviors (b = 0.355, CI [0.247, 0.469]), and environmental determinants and self-reported food safety behaviors (b = 0.269, CI [0.172, 0.393]). Implications, limitations, and direction for future research were discussed.

Research suggests a correlation between high levels of stress and burnout, and low levels of self- efficacy, in school and habilitation professionals. These findings are also prominent in practitioners in Applied Behavior Analysis (ABA) such as teachers, psychologists and Board-Certified Behavior Analysts (BCBAs). This current study aimed to examine the levels in self-reported stress, burnout, and self-efficacy reported in the Ohio State Teacher Efficacy Scale (OSTES), in a Swedish-speaking sample consisting of sixty-seven participants based in school settings, and twenty-five participants based in habilitation settings. All participants were divided into two subgroups: one group who have stated participation in formal post-graduate ABA-training (n = 31), and a group without formal ABA training (n = 61). The hypotheses formulated from previous research were: 1) Teacher Efficacy levels are higher in professionals with ABA-training; 2) Stress-levels are lower in professionals with ABA- training; 3) Burnout levels are lower in professionals with ABA-training; 4) Stress-levels are lower in professionals working in habilitation settings; 5) Burnout levels are lower in professionals working in habilitation settings. Analyzes showed that stress correlated highly positive with burnout, and that teacher efficacy had a negative correlation with stress and burnout. Furthermore, no differences in stress and burnout levels were found between participants from school and habilitation, but the levels in Self-reported Stress and Self-reported Burnout were lower in the ABA group, which therefore confirmed the predictions. Reported OSTES-levels were higher in the ABA-group, but at non- significant levels (except in the sub-item “Efficacy for instructional strategies” where significant levels were found). The conclusion was that educators high in teacher efficacy may be less likely to suffer from stress and burnout, than low-efficacy educators. To address the growing problem of stress-related diseases among Swedish school and habilitation staff, the current teacher efficacy-levels in these occupations must be further highlighted. / Forskning tyder på en korrelation mellan höga nivåer av stress och utbrändhet, och låga nivåer av self- efficacy hos personal i skola och habilitering. Dessa forskningsresultat är också framträdande gällande utövare av tillämpad beteendeanalys (TBA), såsom lärare, psykologer och certifierade beteendeanalytiker (BCBA). Den aktuella studien syftade till att undersöka nivåerna i självrapporterad stress, utbrändhet och self-efficacy baserat på Teacher efficacy-skalan Ohio State Teacher Efficacy Scale (OSTES), gällande ett urval av svensktalande deltagare bestående av sextiosju personer som arbetar inom skolan och tjugofem personer som arbetar inom habiliteringen. Samtliga deltagare delades in i två undergrupper: en grupp som tidigare genomfört en formell TBA-utbildning (n = 31) och en grupp utan formell TBA-utbildning (n = 61). Hypoteserna utifrån tidigare forskning var: 1) Teacher efficacy-nivåerna är högre hos yrkesverksamma med TBA-utbildning; 2) Stressnivåerna är lägre hos professionella med TBA-utbildning; 3) Utbrändhetsnivåerna är lägre hos professionella med TBA-utbildning; 4) Stressnivåerna är lägre hos yrkesverksamma som arbetar inom habiliteringsyrken; 5) Utbrändhetsnivåerna är lägre hos professionella som arbetar inom habiliteringsyrken. Analyserna visade att stress korrelerade mycket positivt med utbrändhet och att Teacher efficacy-nivåerna hade en negativ korrelation med stress och utbrändhet. Vidare hittades inga skillnader i stress- och utbrändhetsnivåerna mellan deltagare från skola och habilitering, men nivåerna i självrapporterad stress och självrapporterad utbrändhet var lägre i TBA-gruppen, vilket därför bekräftade denna förutsägelse. Nivåerna erhållna i OSTES-skalan var högre i TBA-gruppen, men på icke-signifikanta nivåer (förutom i underkategorin “Efficacy for instructional strategies” där signifikanta nivåer hittades). Slutsatsen var att lärare med hög Teacher efficacy kan vara mindre benägna att drabbas av stress och utbrändhet än lärare med låg Teacher efficacy. För att ta itu med det växande problemet med stressrelaterade sjukdomar bland svensk skol- och habiliteringspersonal måste de aktuella nivåerna av Teacher efficacy i dessa yrken belysas ytterligare.

The purpose of this study was to determine the construct validity of self-reported historical walking, running, and jogging (WRJ) activity. The criterion measure was concurrent performance on a maximal treadmill test. Subjects completed a medical exam and treadmill test between the years 1976 and 1985, and completed a follow-up questionnaire in 1986. Questionnaire included an item that assessed WRJ for each year from 1976 through 1985. Data analysis included Spearman correlations, partial correlations, ANOVA, and ANCOVA. Results indicated self-reported historical WRJ can be assessed with reasonable validity when compared with concurrently measured treadmill performance, and there is no decay in the accuracy of this reporting for up to ten years in the past.

This study was predicated on the belief that a father brings something unique to the family, thus, making irreplaceable contributions to the life of a child. Fathers are unique in that they provide something different from mothers. They are irreplaceable because when they are absent, children are said to suffer emotionally, intellectually, socially, and behaviorally. The contributions of fathers to a child's well being cannot be fully replaced by better programming, ensuring child support programs, or even by well-intentioned mentoring programs. A review of literature relevant to delinquency and adolescent behavioral and academic success revealed that there may be a correlation between a male role-model and the teaching of self-control and socially appropriate behaviors. Indeed, much of what the large body of research pertaining to fatherhood reveals is that, compared to children raised in two-parent homes, children who grow up without their fathers have significantly worse outcomes, on average, on almost every measure of well being (Horn, 2002). In addition, an understanding of the factors that may influence delinquent behaviors, in particular within the family unit, can better equip parents and educators to support those who may be exhibiting the beginning signs of delinquent behavior. This study was designed to determine the influence of, or correlation between, juvenile delinquency and the presence or absence of a father-figure in a child's life. Responses made on the Delinquency Check List between two sample sets, delinquent and non-delinquent adolescents, were examined. The study attempted to determine if delinquent activity among adolescents was differentiated by the absence or presence of a father-figure in a child's life. This study also investigated the frequency and severity of delinquent activities between adolescents in the determined sample groups.

Currently there is extensive literature on evidence-based practices (EBP) for students with autism spectrum disorder (ASD). However, there is limited research on whether or not these practices are implemented in the classroom by teachers serving students with ASD. Special education teachers are responsible for the learning outcomes of students across a range of ages and disabilities. This study investigated teachers' self-reported use of EBP and what factors influence implementation. Participants included 129 special education teachers in Texas public schools. Data utilizing descriptive statistics and logistic regression was conducted to determine what factors (i.e., education, employment, teaching experience and training methods) predicted implementation of a particular practice. Although 67% of teachers reported using EBPs, teachers' employment and training experiences did not predict the implementation of a particular practice. Information from this study can be used to enhance professional development for teachers serving students with ASD.

Stress är ett växande problem i dagens samhälle, allt fler barn och ungdomar mår sämre på grund av den ökande stressnivån. Barn och ungdomar befinner sig stora delar av sin vakna tid i skolan. Inom denna arena är stress vanligt förekommande, vilket utgör vikten att arbeta mot den ökande stressnivån. Studier och rapporter visar på att den psykiska ohälsan och stress har ökat och då främst inom skolan. En lagom mängd stress gör att prestationen ökar vilket är en positiv följd av stress. Dock är nivåerna av stress höga och blir inte hanterbara för barn och ungdomar som vistas i stressiga miljöer. Syftet med studien är att undersöka förekomsten och könsfördelningen av stress bland ungdomar i Västmanlands län samt eventuella samband mellan stress och sömnbesvär respektive självskattad hälsa. För att besvara syftet användes data från Liv och hälsa ung Västmanland 2012 undersökning, vilket är en hälsoundersökning som omfattar 6675 studenter i årskurs 7 och 9 samt årskurs 2 på gymnasiet. Studiens resultat visar att stress är vanligt förekommande, där nästan en tredjedel (29.5 %) ofta eller mycket ofta känner sig stressade, vilket motsvarar drygt 2000 barn och ungdomar. Resultatet visar på samband mellan ökad stress och ökade sömnbesvär och mellan ökad stress och sämre självskattad hälsa. Som teoretisk anknytning för stress användes krav/kontroll/stöd-modellen. Coping som förklarande teori användes för att tolka sambandet mellan stress och sömnbesvär. Känsla av sammanhang (KASAM) användes för att tolka sambandet mellan stress och självskattad hälsa. / Stress is a growing problem in today's society, more and more children and adolescents are feeling bad because of the increased stress levels. Children and adolescents spend most of their time in school. Stress is one of the most common problems in this arena, which makes it crucial to work preventive against stress in schools. Studies have shown that the mental illness and stress has increased, primarily within schools. Low levels of stress enhance performance and are therefore a positive aspect of stress. However the levels of stress are high and not manageable for the children and adolescents who spend time in stressful environments. The purpose of the study was to investigate the prevalence and gender distribution of stress among adolescents in Västmanlands län, and potential relation between stress and insomnia respective self-reported health. Data from Liv och Hälsa Ung Västmanland 2012, which investigates health among students, has been used. Data includes 6675 students in grade 7 and 9 in elementary school and grade 2 in upper secondary school. The results shows that stress is a common problem, where almost a third of the participants (29.5 %) often or very often feel stressed, which corresponds to about 2000 adolescents. Results show a significant relation between stress and increased insomnia as well as between stress and self-reported health. The demand/control/support model was used as a theoretical explanation for stress. Coping as an explaining theory was used to interpret the relation between stress and insomnia. Sense of Coherence was used to explain the relation between stress and self-reported health.
