As a social species, human beings are driven by an innate desire to belong and are thus motivated to develop and maintain meaningful social relationships. As such, perceiving a lack of belongingness strongly impacts psychological and physiological health and well-being. A common form of perceived relationship deficits is loneliness, a negative-affective experience detrimental to health and well-being over time. Through a series of three manuscripts, this dissertation applies the full-cycle model of social psychological research to explore various affective, behavioral, and cognitive consequences of loneliness. Whereas existing models of loneliness focus on long-lasting or chronic forms of loneliness, these studies investigate chronic and transient loneliness, as well as processes through which transient loneliness may develop into more chronic levels. The first paper demonstrates that solitary consumption is a unique behavioral response to transient loneliness, which may exacerbate the experience of loneliness and negatively impact health over time. The second paper provides support for a positivity-deficit perspective, demonstrating that chronic loneliness is related to less disclosure of recent positive experiences, a deficit which may be consequential for the development of close relationships. The third paper demonstrates the role of transient loneliness in inhibiting individuals and their interaction partners from reaping the social rewards of positive-event disclosure, particularly among those who typically feel socially connected. Taken together, these studies expand the current understanding transient loneliness, revealing various social-cognitive and behavioral consequences which could impede the social-reaffiliation process, and thus contribute to the maintenance of loneliness over time.

Durch die Veröffentlichung der Ergebnisse im Rahmen dieses Sammelbandes werden die Forschungsprojekte zudem für ein breites Publikum sichtbar gemacht.

Humans’ social relationships determine to a large degree their trajectories in life. Despite strong evidence for the impact of interpersonal relations on wellbeing, the causal links between the two are not yet fully understood. This dissertation offers a new perspective on the mechanisms through which social ties influence negative (excessive drinking) and positive (participation in recreational activities) health behaviors. In three studies employing a unique combination of social network, fMRI, and experience-sampling methods, we propose that health decisions are the result of complex computations involving prior social experiences, perceived social norms, social comparison processes, and current feelings of connections. Each chapter of this dissertation discusses one of these three studies. Chapter 1 provides evidence that past social experiences shape valuations of new information by showing that pairs of students that drink often together tend to have more similar neural responses to novel alcohol cues in regions associated with affective self-generated thought. In addition, this Chapter suggests that researchers must consider the intricate interplay between individuals’ personal goals and their communities’ norms to understand the influence of social environments on neural representations. The degree to which students aligned their neural response patterns to alcohol with those of their peers depended on interactions between their individual motives for drinking and their group’s approval of this behavior. Chapter 2 presents novel findings that people spontaneously represent social information from multiple networks (e.g., popularity and leadership) at a neural level in social cognition (right TPJ, dmPFC) and valuation (vmPFC) regions. Importantly, individuals who display higher neural sensitivity to status differences are also more likely to align their drinking behavior with their group norms in daily life. Together, our results provide insight into the neural mechanisms through which social comparison processes shape conformity and suggest social cognition and valuation regions as important hubs orchestrating this process. While Chapter 1 and Chapter 2 focus on the influence of social ties on drinking, Chapter 3 discusses the protective role of close relations during difficult times. We provide evidence that close college friendships, even if afar, helped young adults cope with the stress of the COVID-19 pandemic. Follow-up between- and within-individual analyses reveal that this buffering effect could be explained by differences in the quality of online interactions (e.g., via phone, text messaging), instances of personal disclosure, and participation in enjoyable activities. All in all, this dissertation advances our understanding of why measures of social wellbeing are the best predictor of health trajectories in life, by highlighting the important role social ties play in shaping valuation of new information, guiding behavior to meet social goals, and protecting against stress by allowing people to engage in recreational activities.

Introduction. HIV positive men who have sex with men (HIVMSM), facing severe stigma and many stressors, have high prevalence of mental health problems, such as depression. However, there is a lack of mental health promotion and treatment services targeting HIVMSM in China. The Three Good Things (TGT) exercise is one of the commonly used positive psychology interventions; its benefits in reducing depression have been scientifically proven in many disease groups. Yet, TGT has not been applied among HIVMSM. In addition, social support has shown to be protective of depression. The emergence of electronic social media allows for integration of social networking and TGT exercise among HIVMSM. / Objectives. This study aimed to evaluate the efficacy of a one-month online intervention combining TGT with social networking (TGT-SN) versus a control of dissemination of information in reducing depressive symptoms among HIVMSM in Chengdu, China. / Methods. A randomized controlled trial design was applied. A total of 205 HIVMSM were recruited and randomly assigned to the TGT-SN (N=100) or control group (N=105) by four well-trained peer fieldworkers. Self-administered surveys were given to all participants at baseline, at the end of the 1-month intervention (T1), and at the 3-month (T2) and 6-month (T3) post-intervention follow-ups. The intervention was delivered via “QQ”, the most widely used Chinese social networking service. Participants in TGT-SN group were divided into four “QQ” groups, each the size of 20-30 persons. Participants in TGT-SN were asked to post three things they experienced that they feel grateful about daily onto the QQ platform and share them with members of their group. They were also asked to read others’ messages and give positive and encouraging feedbacks to those messages. Members of the control group received information about mental health promotion from research assistants via QQ once a week during the one-month intervention period. The primary mental health outcome was probable case of mild to severe depression measured by Center for Epidemiologic Studies Depression Scale (CES-D). Secondary psychological outcomes include depressive symptoms, anxiety, positive and negative affect, life satisfaction, subjective happiness, gratitude level, and perceived social support. Generalized Estimating Equation models were fit. Structural equation modeling was applied for mediation analysis. / Results. Among all participants, the prevalence of probable mild, moderate, and severe depression were, respectively, 14.6%, 9.3%, and 35.6% at baseline. All baseline background characteristics and outcome measures were balanced (statistically non-significant) between the two groups. Based on data obtained at T1, T2 and T3 that were analyzed by GEE model, there was a significant main effect of TGT-SN on reducing depression (B=-2.35, 95% CI=-4.53, -0.16, p=0.035), indicating significantly lower depression score in the intervention group as compared with that of control group. Nonetheless, such significant effect became non-significant (B=-1.67, 95% CI=-3.79, 0.46, p=0.124) when controlled for baseline depression score. Significant differences were also found between the TGT-SN and the control group in anxiety symptoms (B=-1.14, 95% CI=-2.06, -0.22, p=0.016) and negative affect (B=-2.08, 95% CI=-3.62, -0.55, p=0.008). The effect of TGT-SN on reducing depression was most evident at T3. Structural equation modeling indicated that gratitude and negative affect fully mediated the effect of TGT-SN in reduction of depression and anxiety (mediation effect=-0.17, 95% CI=-0.30, -0.04, p<0.05) at T3. / Conclusions. TGT-SN is a feasible, acceptable, sustainable, and scalable intervention to improve mental health among HIVMSM. It is warranted to increase awareness and policy support for mental health services for people living with HIV (PLWH). Mental health services should be integrated into the HIV/AIDS care system as a key component. Future translational studies are needed to further investigate the efficacy and effectiveness of the intervention in other groups of PLWH and in other cultures and countries. / 研究背景：艾滋病在男男性接觸（men who have sex with men, MSM）人群中的感染率正在以前所未有的速度在我國蔓延。艾滋病陽性的男男性接觸（HIV positive men who have sex with men, HIVMSM）人群面臨極大的壓力，心理疾病（例如抑鬱症）的患病率很高。但是，目前我國對HIVMSM人群的心理健康服務比較缺乏。“三件好事情”是最被廣泛使用的能有效降低抑鬱症的積極心理學干預。這項練習要求參與者每天寫下三件令他們感到高興或者感激的事情。“三件好事情”這兩練習還沒有在HIVMSM 人群中應用。此外，社會支持對抑鬱症有保護作用。電子社交網絡是一種潛在的有效的平台，可以將調查對象（HIVMSM）的“好事情”相互傳遞，加強“三件好事情”的效果。 / 研究目的：本研究的目的是在中國成都市使用隨機對照研究評估積極心理學結合社會網絡干預對減少HIVMSM人群抑鬱症的效果。 / 研究方法：本研究採用隨機對照試驗。四名同伴調查員共招募205位HIVMSM，其中100人被隨機分配到“三件好事情結合電子社交網絡組（TGT-SN）”，105人被分配到對照組。所有參與本研究的調查對象將在隨機分組之前完成基線調查（T0），並在一個月的干預結束時（T1）、干預結束后三個月（T2）、十二個月（T3）時完成隨訪調查。 / TGT-SN干預通過騰訊QQ實施。騰訊QQ是在中國最被普遍使用的社交網絡。TGT-SN組的調查對象將被分配到4個QQ組，每組20-30人。TGT-SN干預要求調查對象在一個月的干預期，每天需要完成以下三個任務：i）每天回想當天發生的三件或以上令自己開心、感激的事情，并將這三件好事情發佈到各自的QQ群留言板；ii）每天閱讀本QQ群其他組員發佈的三件好事情；iii）每天對組員發佈的三件好事情進行正面的積極的評論。被隨機分配到對照組的調查對象在一個月的干預期內，每週收到一條有關心理健康促進的信息。 / 本研究的主要結果為抑鬱症狀，採用美國國立衛生研究院流行病學研究中心抑鬱量表。次級結果包括焦慮症狀、正性和負性情緒、生活滿意度、主觀幸福感、感恩心理、以及社會支持。分析採用廣義估計方程模型（GEE）。中介效應分析採用結構方程模型。 / 研究結果：所有調查對象中，59.5%有輕度到重度抑鬱症（CESD≥16）。TGT-SN和對照組基線所有的背景變量及結果變量均無顯著性差異。基於對T1、T2和T3數據的GEE模型分析，相比于對照組，TGT-SN對降低抑鬱症有顯著主效應（B=-2.35, 95% CI=-4.53, -0.16; p=0.035）。但是此顯著主效應在控制基線抑鬱症狀后變為不顯著（B=-1.67, 95% CI=-3.79, 0.46, p=0.124）。相比于對照組，TGT-SN對降低焦慮症狀（B=-1.29, 95% CI=-2.22, -0.36; p=0.007）和負性情緒（B=-2.24, 95% CI=-3.73, -0.74; p=0.003）也有顯著效果。TGT-SN對降低抑鬱症的效果在T3最為顯著。結構方程模型表明，負性情緒和感恩心理對TGT-SN干預降低T3時抑鬱症和焦慮症的效果中發揮完全中介效應（中介效應=-0.17, 95%置信區間=-0.30, -0.04; p<0.05）。 / 研究結論：TGT-SN能有效減少HIVMSM人群的心理健康問題（例如抑鬱症和焦慮症），並且是可行的和被HIVMSM所接受的干預措施。TGT-SN練習的實施成本較低並且不需要心理學專家的參與，因此可以在資源有限的國家和地區（例如中國）推廣實施。未來需要更多的研究來評估TGT-SN干預在其他艾滋病病毒感染者人群中以及其它國家的效力和效果。" / Li, Jinghua. / Thesis Ph.D. Chinese University of Hong Kong 2015. / Includes bibliographical references (leaves 136-149). / Abstracts also in Chinese; some appendixes in Chinese. / Title from PDF title page (viewed on 06, October, 2016). / Li, Jinghua. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only.

The objective of this thesis is to examine which socio-economic, structural and cultural factors may influence Indian women’s propensity to contract HIV and later their ability to access the relevant healthcare services for their condition. The research draws on two theoretical frameworks, the first being Barnett and Whiteside’s (2002) concept of social structural factors of disease transmission. Second, Anderson and Aday’s (1981) model of access examines how a variety of structural and resource-based factors, e.g. area of residence, can influence usage of healthcare facilities. Two stages of data analysis were undertaken, the first being secondary statistical analysis of the National Family Health Survey III. The survey provided state level estimates on the HIV sero-status of the general population in India and data on demographic and socio-economic determinants for family planning, nutrition, utilization of healthcare and emerging health issues. The second stage of analysis consisted of a set of qualitative interviews conducted in Andhra Pradesh, India. Thirty-three interviews were conducted with female sero-positive patients and ten with HIV-infected women who were providing social services to others with the same condition. Statistical results on social structural determinants of HIV transmission illustrated that Indian women who were formerly married (OR=5.27, CI=3.07-9.04), lived in higher prevalence states (OR=3.48, CI=2.19-5.54), had a low level of education (OR=2.27, CI=1.40-3.68) and were employed (OR=1.45, CI=0.96-2.18) had significantly (<.05) higher odds of being HIV-positive in comparison to those who were not. Findings in the qualitative phase of analysis were similar but participants’ narratives illustrated that their risk of contracting HIV begun before they even had the opportunity to seek a match as they seemed to live in communities with a high level of HIV prevalence. Many of the participants commented that there were factors outside of their sphere of control, e.g. lack of education, which resulted in them having a narrow choice of potential partners. Additionally, statistical results on female participants’ access to healthcare services indicated the vast majority of HIV-positive respondents were almost certainly not aware of their sero-status as they had not undertaken an HIV test prior to the survey. As the sample of female HIV infected respondents was relatively small, it was difficult to ascertain which social factors had an impact on these participants utilisation of HIV testing services. On the other hand, respondents’ narratives from the qualitative stage of research highlighted on social structural factors which could potentially influence WLHA’s continual utilisation of HIV-related healthcare services. It was found that participants experienced the most barriers to accessing healthcare facilities in the initial phases of their treatment. These barriers were mediated by the structure of healthcare services, culturally sanctioned medical practices (e.g. physicians refusal to inform the patient of their sero-status) and quality of services.

The dissertation is a compilation of three essays on Turkey's poverty alleviation programs. The first paper focuses on the welfare impact of the global financial Crisis on Turkish households. The second paper considers the protective impact of the Green Card non-contributory health insurance program in Turkey during the Crisis in 2008-2009. The third paper uses experimental data from the field in eastern Turkey, to look at patterns of agricultural technology diffusion in a rural development program implemented in a post-conflict setting.

The collapse of the communist regimes in Central and Eastern Europe in 1989-1990 heralded the beginning of an economic transition from central planning to market economies. The subsequent period was marked by malfunctioning of these countries’ social sectors, including their health care systems, raising serious issues of equity. This thesis examines the impact of the transition period and the introduction of social insurance on equity in health care provision in Bulgaria. Equity in health care is investigated with respect to function - i.e. financing (according to ability to pay) and delivery (according to need) - and outcomes - i.e. health status, income inequality and poverty. Differences in health, health care financing and delivery are explored by income, education, ethnic, employment, marital status, age and sex groups. Furthermore, the thesis outlines the impact of health care provision, in particular social insurance, on poverty and health inequalities. The thesis employs empirical analysis based on household data. Its methodology includes concentration and decomposition analysis, and provides new ways of modelling health care financing and delivery, as well as the link between health and health care delivery. The thesis concludes that social insurance does not provide a uniform means of improving equity and that the root cause of the problem lies in the large proportion of out-of-pocket payments and the rather limited size of the health insurance sector. Inequity in health care provision leads to poverty and untreated illness. The data suggests that there are differences between socio-economic groups as regards their likelihood to seek treatment for their ill health, which result in differences in their health status. The social factors that have impacted the most on health are low education and low income.

The thesis presents rich empirical analysis of the role of public relations in facilitating participation in social change in the Arab Gulf. The focus is on what public communication approaches are used and how they are regarded from the perspectives of the key social actors. It presents an historical and sociological background of public communication and media in the Arab Gulf. Moreover, it provides in-depth analysis of two empirical case studies in the Arab Gulf: Ghiras, the national drugs prevention programme in Kuwait, and Be Free, the voluntary anti-child abuse programme in Bahrain. This thesis relates the practice of public communication in the Arab Gulf society to Arabic culture and ethics. The thesis uses a qualitative constructivist paradigm to “re-construct” the multiple realities initially constructed by social actors in the cases to provide original insights on the role of public communication and public relations in social change in the Arab Gulf. It presents a new perspective of 'social change' in the two cases that is tied to Islamic ethics. Besides, it re-constructs original Arabic-oriented understanding of 'relational' and 'persuasion' approaches, which differs from the Western paradigm. One of the key contributions of the thesis is its adaptation of relevant Western communication models to the empirical Arab Gulf cases to identify some of the crucial factors of the practice and role of public communication in the Arab Gulf. The unique contribution of this thesis is that it develops a greater understanding of alternative cultural context that might contribute to the adaptations of existing theory and therefore a first step towards new models. It introduces a theoretical framework for other scholars to develop an Arabic public communication ethics theory and to build up a cultural model of the practice of public communication and public relations in the Arab Gulf. The thesis generates key theoretical implications that contribute to the theoretical discussion on the value and role of media, public relations, social marketing, and public communication in the Arab Gulf society at the age of globalisation.

At the onset of the First World War, Germany was subject to a shipping embargo by the Allied forces. Ostensibly military in nature, the blockade prevented not only armaments but also food and fertilizers from entering Germany. The impact of this blockade on civilian populations has been debated ever since. Germans protested that the Allies had wielded hunger as a weapon against women and children with devastating results, a claim that was hotly denied by the Allies. The impact of what the Germans termed the 'Hungerblockade' on childhood nutrition can now be assessed using various anthropometric sources on school children, several of which are newly discovered. Statistical analysis reveals a grim truth: German children suffered severe malnutrition due to the blockade. Social class impacted risk of deprivation, with working-class children suffering the most. Surprisingly, they were the quickest to recover after the war. Their rescue was fuelled by massive food aid organized by the former enemies of Germany, and delivered cooperatively with both government and civil society. Children, and those who cared for them, responded to these acts of service with gratitude and joy. The ability of former belligerents to work together after an exceptionally bitter war to feed impoverished children may hold hope for the future.

How we share our good news with people can have a significant effect on our lives. Sharing good news on social media sites involves a process called capitalization. Capitalization has been shown to increase well-being when others provide appropriate responses in face-to-face interactions. To see if this effect on well-being extends to our online presence, this study utilized the social media site Facebook to observe if capitalization predicted well-being and relationship satisfaction. This study used data collected from 137 participants recruited from an undergraduate participant pool and from Amazon Mechanical Turk. Consistent with hypotheses, participants who reported receiving active and constructive responses after sharing a positive event on Facebook also reported greater personal well-being and relationship satisfaction. Although future experimental research is needed to establish causality, the current results suggest that the ways in which friends respond to social media posts are associated with personal and relationship well-being. / Includes bibliography. / Thesis (M.A.)--Florida Atlantic University, 2016. / FAU Electronic Theses and Dissertations Collection
