- Abstract
Background: Distinct monocyte subsets predict cardiovascular risk and contribute to heart failure progression in murine models, but they have not been examined in clinical acute decompensated heart failure (ADHF).Methods and Results: Blood samples were obtained from 11 healthy control subjects (HCs) and at admission and discharge from 19 ADHF patients. Serologic markers of inflammation were assessed at admission and discharge. Monocyte populations were defined with the use of flow cytometry for cell-surface expression of CD14 and CD16: CD14++CD16- (classic), CD14++CD16+ (intermediate), and CD14+CD16++ (nonclassic). In ADHF patients, C-reactive protein (CRP) and interleukin-6 (IL-6) were higher compared with HCs (both P < .001) and decreased from admission to discharge (CRP: 12.1 ± 10.1 to 8.6 ± 8.4 mg/L [P = .005]; IL-6: 19.8 ± 34.5 to 7.1 ± 4.7 pg/mL [P = .08]). In ADHF patients, the admission proportion of CD14++CD16- monocytes was lower (68% vs 85%; P < .001) and that of CD14++CD16+ (15% vs 8%; P = .002) and CD14+CD16++ (17% vs 7%, P = .07) monocytes higher compared with HCs. Additionally, the proportion of CD14++CD16- monocytes increased (68% to 79%, P = .04) and the CD14+CD16++ monocytes decreased (17% to 7%, P = .049) between admission and discharge.Conclusions: Following standard treatment of ADHF, the monocyte profile and circulating inflammatory markers shifts to more closely resemble those of HC, suggesting a resolution of the acute inflammatory state. Functional studies are warranted to understand how specific monocyte subsets and systemic inflammation may contribute to ADHF pathophysiology. [ABSTRACT FROM AUTHOR]- Published

- Abstract
This study investigated the role of breast cancer survivors in a computer-mediated social support (CMSS) group for women with breast cancer. Applying a computer-aided content analytic method, the present study examined the differences in support provision between survivors and newly diagnosed patients. This study further investigated the impacts of survivor-provided social support on psychosocial adjustment of newly diagnosed patients. The results revealed that, compared with newly diagnosed patients, breast cancer survivors provided more emotional and informational support. Receiving emotional support from survivors contributed to an improvement in the quality of life and the depression of patients. The effects of survivor-provided informational support were not significant.

Media Perceptions are a fixture of modern electoral politics. . In this paper, we explore potential sources of these perceptions in the socialization of young people into citizenship during their adolescent years. To explore these issues, we rely on data collected from a national cross-section of 12-17 years olds and their parents. Our analysis examines how demographic, ideological, conversational, and informational variables shape judgments of news credibility among American youth, our future voters. Our results demonstrate that factors such as political interest, opinion leadership and "echo chamber" variables play a significant role. Unlike adults partisanship or partisan strengths do not have significant influences in the media perceptions of adolescents. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]

CULTURE ,LIFESTYLES ,INTERPERSONAL relations ,POLITICAL participation - Abstract
In this paper, we analyze the field of cultural consumption in the United States, drawing on the methods of correspondence analysis employed by Bourdieu (1979, see also Greenacre, 1993). Using the 2000 DDB Lifestyle Study, we analyze a cross section of Americans (N=3,122) in terms of the associations among occupational categories, media usage, consumption practices, social behaviors, and indicators of civic and political engagement. In doing so, we find many parallels to the determinants of taste, cultural discrimination, and choice within the field structure observed by Bourdieu in 1970s French society, though there are also some notable differences. Most notable is the important role occupied by media consumption in defining the field of cultural consumption. The characteristics we map are arrayed along two axes of volume and form of economic and cultural capital. We find striking similarities in the upper ranges of the quadrants mapping a high volume of cultural and economic capital, but substantial differences toward middle and lower levels. Specifically, we find that in terms of the form of cultural capital, the distribution of positions is largely defined by patterns of taste that discriminate between refinement, moderation, nurturance, and a communal orientation, on the one side, and coarseness, excess, aggressiveness, and an individual orientation, on the other. Historical and national differences partly account for this variation, but we hypothesize that a major role is played by the formation of identities around media and consumption, leading to a more gendered and ideological positioning of taste cultures in the U.S. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]

Recent research has found that the levels of incivility in televised debate exchanges adversely affect political legitimacy, particularly when the appearance of contentiousness is intensified through the use of broadcast production techniques such as close-up camera perspectives (Mutz & Reeves, 2005). Our experimental research builds on these findings to examine how different modalities of presidential debate presentations (single screen or split screen) and post debate spin (no spin, policy focused, or performance focused) influence judgments of political trust and news credibility. No direct effects of these manipulations are observed, but building on work by Eveland and Shah (2003), we find that political talk conditions certain experimental effects on perceptions of news credibility, but not political trust. Specifically, news credibility is adversely affected by the use of split screen presentations, but only among those who engage in higher levels of political talk. Thus, it appears that the negative effects of “in your face” politics may be reserved for those more attuned to politics through the interpersonal exchange of views on policy and government and limited in scope to judgments about media credibility, not political trust. ..PAT.-Conference Proceeding [ABSTRACT FROM AUTHOR]

This article examines the contribution of offline and online news consumption and political discussion to civic participation during the period leading up to the Iraq war in 2003. The interpersonal utility function explains that people consume news content specifically so that they can relay that information to others and discuss issues more persuasively.

The article investigates the interplay of news frames and political predispositions on the complexity of individuals' cognitive responses. The social level of the news frame and the affective reactions generated by the cause predisposition and their interplay are expected to shape the extent of cognitive processing. Frames are thought to exploit widely shared heuristics and cognitive biases such that the effects are typically conceived as occurring across all people. Insight into the effects of news frames and emotional responses on cognitive processing and complexity can be found in research on framing effects and inferential processes, work on threat perceptions triggered by political predispositions and studies of network models of memory.

Scholars in various fields have criticized the the commercialized content of the media by suggesting that media driven consumer culture diminishes civic-mindedness. Nonetheless, some scholars argue that consumer and civic culture are not separate entities, but instead are inextricably linked with positive interrelationships. Despite a history of discussion surrounding these relationships, they are only beginning to be empirically investigated. Thus, this study examines the influences of media on indicators of consumer and civic culture. Further, the interrelationships of civic participation with consumption activities are considered. In so doing, the role of opinion leadership is included, due to the possibility that individuals who have leadership traits are likely to be leaders in media use, consumption, and participation. To explore these issues, this study performed a secondary analysis of the 2000 DDB Life Style Survey data with a sample of 3,122 adults. A series of hierarchical regressions and correlations were used to test study hypotheses. The results showed that the use of informational media motivates status-conscious consumption, socially conscious consumption, and civic participation. More importantly, the endogenous core of civic participation and consumption activities were all positively interrelated. Underlying these relationships is opinion leadership, which indirectly influences both citizen and consumer activities mediated through media use. In addition, the results indicate that opinion leadership is the common factor behind the positive dynamic between consumer and citizen activism. [ABSTRACT FROM AUTHOR]

10. Discussion and Participation in the Wake of 9/11: Panel Analysis of Lagged and Concurrent Relationships.

- Abstract
This paper examines the relationship between citizen communication and civic participation. Past research has theorized that political discussion encourages participation by providing exposure to public affairs information and interpersonal pathways to civic recruitment. Others suspect that discussion is a consequence of participation, with experience anchoring attitudes and encouraging expression. Merging these perspectives, we hypothesize a set of relationships in which the size of interpersonal discussion networks explains change in levels of political participation and frequency of political talk, with these two variables reciprocally related to one another. To overcome the limitations of cross sectional studies, hypotheses were tested using panel data from a community survey. Testing for both lagged and concurrent effects, our results suggest that discussion network size is antecedent to civic participation, whereas more frequent political talk is an outcome of participation. We also observe concurrent effects between changes in levels of participation and changes in frequency of discussion. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]

- Abstract
The USA Patriot Act enacted by Congress in the wake of the September 11 terrorist attacks has stirred public debate about the tradeoff between domestic security and civil liberties. In light of this debate, this 2 x 2 experiment presented participants with news stories about government efforts to restrict the civil liberties of an "extremist" individual or group (news frame) advocating for a cause either supported or opposed by the respondent (cause predisposition). Results indicate that willingness to take expressive action was greatest for individual-framed stories about a cause opposed by the respondent, and for group-framed stories about a cause supported by the respondent. This study underscores the conditional nature of media framing effects. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]

- Abstract
Numerous studies have demonstrated a relationship between community attachment and local news media use. However, despite calls for panel studies to help determine the direction of causality in this relationship, there is little in the way of evidence beyond cross-sectional surveys, and these surveys are most often limited to single communities. In order to help provide empirical data to help settle the longstanding debate about the direction of this relationship, we conducted a four-wave national panel study with repeated measurement of community attachment and local news media use across waves two, three and four, with antecedent demographic and structural variables measured in the first wave. Cross-sectional analyses confirmed the expected relationship between news use and community attachment, but more conservative panel analyses with control for prior levels of outcome variables indicated no significant relationships. An additional prediction about the role of community size as a moderator of the relationship between local news use and community attachment was not supported. We discuss methodological and theoretical reasons for the lack of support for these hypotheses and make suggestions for alternative study designs for future research. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]

- Abstract
A growing body of literature on communication and community emphasizes contextual effects, often with limited methodological correspondence to their theoretical arguments. The present study empirically tests the multi-level nature of community engagement by performing hierarchical linear modeling, which assesses both individual-level and community-level effects and variances. This study examines whether the effects of the individual-level variables on participation differ across communities, and if so, which community-level variables explain such variability. We find that individuals' residential tenure and home ownership, sociability, life satisfaction, and local newspaper have a positive influence on engagement. The data also reveal that the effects of variables at the individual-level differed across communities. In addition, we find cross-level interaction effects, which indicate that in communities where average homeownership is higher, the effects of certain individual-level variables - life satisfaction, sociability, and local newspaper reading - became stronger. Notably, the non-significant effect of national newspaper reading at individual-level becomes significant where residents have a higher level of national newspaper readership (community-level). Implications of the results, important issues for studies in contextual effects, and future directions are discussed. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]

This study merges insights from extant cultivation research with a media uses and gratifications perspective to examine the relationship between environmental concern, five forms of television viewing, and pro-environmental behaviors. In doing so, we consider a host of variables, including environmental attitudes, that are exogenous television use and environmental behaviors and may motivate certain viewing patterns and social actions. Thus, perspective advanced by this research considers both the direct effects of various forms of television viewing and their potential mediating roles in the relationship between environmental attitudes and behaviors. Analysis of 1999 and 2000 DDB Life Style Study data reveals that television public affairs and nature documentary use, the genres of programming that give tangible and visible form to abstract environmental issues, are predicted by environmental concern and contribute to pro-environmental behaviors, whereas the three forms of entertainment television use are not consistently linked to these variables. Public affairs and nature documentary use were also found to be important mediators of the effects of other exogenous variables on pro-environmental behaviors. Implications for future research are discussed. [ABSTRACT FROM AUTHOR]

In recent years, many scholars have bemoaned declining levels of social trust and civic engagement in our society, yet there is a group of citizens that does participate actively in civic life and that is strongly involved in the community -- opinion leaders. Scheufele and Shah (2000) found that opinion leadership, or personality strength, is linked to civic engagement both directly and indirectly, mediated by various communication variables. However, they do not offer a complete theoretical account explaining the nature of these influences that relates them to the specific patterns of media use that foster participation. Accordingly, we explicate the construct of opinion leadership, outline it causes and consequences, and then examine hypothesized relationships using data from a large national survey conducted in 1998. We examine opinion leadership as an endogenous variable within a structural equation model. Our analyses show that opinion leadership is less a function of demographic variables than a number of psychological factors related to levels of self-esteem and confidence in one's own abilities. In addition, we find opinion leaders are strategic in their media use, with television hard news use prompting newspaper hard news use and subsequent on-line information search. Particularly important, the link between opinion leadership and media use is largely mediated by interest in politics, which triggers information seeking across all types of media. In turn, interest in politics, newspaper reading, and on-line searching are significant direct predictors of civic engagement. Implications for future research and practice are discussed.

This research explores the relationship between Internet use and gratifications gained within the context of digital divide. Analyses within sub-samples defined by age and socio-economic status reveal that there are notable differences across the subcategories. For instance, those that are young and high in socioeconomic status are most likely to use the Internet to strategically satisfy their motivations and gain the desired gratifications. They are most likely to engage in specific Internet behaviors -- computer-mediated interaction, surveillance, and consumption uses -- to achieve particular gratifications -- connection, learning, and acquisition, respectively. In contrast, respondents who were low in socio-economic status and young were particularly likely to employ consumptive use of the Internet to attain connection gratifications. Similarly, both low socioeconomic status subgroups, regardless of age, were likely to use computer-mediated interaction as a means to gain learning gratifications. We concluded that even if gaps in access are closing, gaps in usage and gratifications gained may persist. Further implications for digital divide will be discussed. [ABSTRACT FROM AUTHOR]

- Abstract
In the online news environment, audience information processing may be influenced by the framing not only of a news story itself but also of other messages that introduce, link to, or accompany the news content. We test these mixed media framing effects on audience reason acquisition from news content with an experiment, in which we manipulate the frame—value or strategy—of a text introduction about the issue of stem cell research, followed by exposure, or no exposure, to a video news report about stem cell research. Value framing (as opposed to strategy framing) prior to a news story increased the number of reasons for one’s own side of the issue acquired from the news report, but no effects were found on learning reasons for the other side.

- Abstract
A sizable body of empirical evidence indicates political conversation—both face-to-face and online—drives participatory engagement. Digital, social, and mobile media provide new avenues and tools for political talk, with affordances that may be particularly conducive to expression effects—that is, the impact of message production on the sender. This essay contends that an emphasis on deliberative democracy has limited attention to the psychological implications of political expression and creative production via information technologies and digital media.

- Abstract
Importance: Patients leaving residential treatment for alcohol use disorders are not typically offered evidence-based continuing care, although research suggests that continuing care is associated with better outcomes. A smartphone-based application could provide effective continuing care.Objective: To determine whether patients leaving residential treatment for alcohol use disorders with a smartphone application to support recovery have fewer risky drinking days than control patients.Design, Setting, and Participants: An unmasked randomized clinical trial involving 3 residential programs operated by 1 nonprofit treatment organization in the Midwestern United States and 2 residential programs operated by 1 nonprofit organization in the Northeastern United States. In total, 349 patients who met the criteria for DSM-IV alcohol dependence when they entered residential treatment were randomized to treatment as usual (n = 179) or treatment as usual plus a smartphone (n = 170) with the Addiction-Comprehensive Health Enhancement Support System (A-CHESS), an application designed to improve continuing care for alcohol use disorders.Interventions: Treatment as usual varied across programs; none offered patients coordinated continuing care after discharge. A-CHESS provides monitoring, information, communication, and support services to patients, including ways for patients and counselors to stay in contact. The intervention and follow-up period lasted 8 and 4 months, respectively.Main Outcomes and Measures: Risky drinking days--the number of days during which a patient's drinking in a 2-hour period exceeded 4 standard drinks for men and 3 standard drinks for women, with standard drink defined as one that contains roughly 14 g of pure alcohol (12 oz of regular beer, 5 oz of wine, or 1.5 oz of distilled spirits). Patients were asked to report their risky drinking days in the previous 30 days on surveys taken 4, 8, and 12 months after discharge from residential treatment.Results: For the 8 months of the intervention and 4 months of follow-up, patients in the A-CHESS group reported significantly fewer risky drinking days than did patients in the control group, with a mean of 1.39 vs 2.75 days (mean difference, 1.37; 95% CI, 0.46-2.27; P = .003).Conclusions and Relevance: The findings suggest that a multifeatured smartphone application may have significant benefit to patients in continuing care for alcohol use disorders.Trial Registration: clinicaltrials.gov Identifier: NCT01003119.

- Abstract
The intersection of consumer culture and civic life has long been a topic of academic discussion. This study revisits the relationship between consumption and civic engagement and investigates the moderators of this relationship. Specifically, we focus on news consumption and opinion leadership as intervening factors that condition the way consumption and civic life are interconnected. Our data reveal that both socially conscious consumption and status-oriented consumption are positively related with civic participation. The positive relationships become stronger when news consumption increases or when one’s opinion leadership is strong. Implications for research on consumer culture and civic engagement are discussed.

- Abstract
Tailored within the increasingly competitive news environment, political talk shows have adopted a range of styles, heralding a rise in “combatant” and “comic” hosts to complement the conventional “correspondent.” Using an experimental design to rule out self-selection biases, this study isolates the impact of host style on media judgments. In comparison to the other styles, the correspondent host increases perceptions of informational value, enhances host and program credibility, and reduces erosion of media trust, while a comic host mitigates some of the negative impact compared to a combatant host. Implications for media accountability and democratic functioning are discussed.

- Abstract
After more than a decade of public journalism efforts, empirical knowledge of whether these efforts have met the movement's goals remains largely based on in-depth case studies. To address this shortcoming, this study analyzes 651 cases of public journalism conducted between 1994 to 2002. Hierarchical multiple regression analysis is used to consider the predictive power of organizational factors, project features, story frames, and efforts to engage citizens and assess public opinion on three civil society outcomes: improvements in citizenship, political processes, and volunteerism. Specific effects on civil society are discussed, study limitations are addressed, and insights for future research and practice are offered.

- Abstract
This study explores the cross-level interactions of local media use with individual and community factors, in particular, local print news use, using a multi-level analysis of community participation. Findings show local print news readership, an essential constituent of communal solidarity, increases the likelihood of community participation both at the individual level and as a function of readership in communities with higher levels of social interaction. Cross-level effects are also observed between individual-level differences in social interaction and home ownership and contextual variation in print news readership.

- Abstract
Based on uncertainty reduction theory, this paper argues that individuals were motivated to seek information and learn about the September 11 terrorist attacks to reduce uncertainty about what happened. Results from a panel survey indicate that negative emotional response was a strong predictor of efforts to learn. Analyses also show that relative increases in newspaper, television, and Internet use from Wave 1 to Wave 2 were positively related to efforts to learn about the attacks. The findings extend uncertainty reduction theory to the mass media context thereby contributing to our understanding of uses and gratifications.

26. Fear, Authority, and Justice: Crime-Related TV Viewing and Endorsements of Capital Punishment and Gun Ownership

Holbert, R., Shah, Dhavan, and Kwak, Nojin
- Abstract
We focus on the relationships among three types of television viewing (news, police reality, and crime drama) and attitudes toward capital punishment and handguns, as well as the likelihood of actually owning a handgun. A host of exogenous variables are treated as predictors of television use, support for police authority, fear of crime, and our criterion variables. A series of direct and indirect relationships are assessed. Analysis suggests that viewing police reality shows is both directly and indirectly related to the endorsement of capital punishment and handgun ownership, while also directly predicting a greater likelihood of actual handgun ownership. In addition, TV news viewing predicts fear of crime in audience members, and this fear contributes to the endorsement of capital punishment and handgun ownership. Crime drama viewing is positively related to support for the death penalty.

- Abstract
Although some argue that Internet use may erode involvement in public life, the most common Internet behaviors, social communication and information searching, may actually foster social and civic participation. To examine this possibility, we test a series of non-recursive models using a national survey of nearly 3,400 respondents. Two-stage least squares regressions were performed to simultaneously test the reciprocal relationship between frequency of Internet use (i.e., hours per day) and three sets of community engagement behaviors: informal social interaction, attendance at public events, and participation in civic volunteerism (i.e., annual frequency). Time spent online has a positive relationship with public attendance and civic volunteerism. No evidence of time displacement from frequency of Internet use is observed.

Background: Multiple chronic conditions (MCCs) are common among older adults and expensive to manage. Two-thirds of Medicare beneficiaries have multiple conditions (eg, diabetes and osteoarthritis) and account for more than 90% of Medicare spending. Patients with MCCs also experience lower quality of life and worse medical and psychiatric outcomes than patients without MCCs. In primary care settings, where MCCs are generally treated, care often focuses on laboratory results and medication management, and not quality of life, due in part to time constraints. eHealth systems, which have been shown to improve multiple outcomes, may be able to fill the gap, supplementing primary care and improving these patients' lives. Objective: This study aims to assess the effects of ElderTree (ET), an eHealth intervention for older adults with MCCs, on quality of life and related measures. Methods: In this unblinded study, 346 adults aged 65 years and older with at least 3 of 5 targeted high-risk chronic conditions (hypertension, hyperlipidemia, diabetes, osteoarthritis, and BMI ≥30 kg/m2) were recruited from primary care clinics and randomized in a ratio of 1:1 to one of 2 conditions: usual care (UC) plus laptop computer, internet service, and ET or a control consisting of UC plus laptop and internet but no ET. Patients with ET have access for 12 months and will be followed up for an additional 6 months, for a total of 18 months. The primary outcomes of this study are the differences between the 2 groups with regard to measures of quality of life, psychological well-being, and loneliness. The secondary outcomes are between-group differences in laboratory scores, falls, symptom distress, medication adherence, and crisis and long-term health care use. We will also examine the mediators and moderators of the effects of ET. At baseline and months 6, 12, and 18, patients complete written surveys comprising validated scales selected for good psychometric properties with similar populations; laboratory data are collected from eHealth records; health care use and chronic conditions are collected from health records and patient surveys; and ET use data are collected continuously in system logs. We will use general linear models and linear mixed models to evaluate primary and secondary outcomes over time, with treatment condition as a between-subjects factor. Separate analyses will be conducted for outcomes that are noncontinuous or not correlated with other outcomes. Results: Recruitment was conducted from January 2018 to December 2019, and 346 participants were recruited. The intervention period will end in June 2021. Conclusions: With self-management and motivational strategies, health tracking, educational tools, and peer community and support, ET may help improve outcomes for patients coping with ongoing, complex MCCs. In addition, it may relieve some stress on the primary care system, with potential cost implications.

Background: The growing epidemic of opioid use disorder (OUD) and associated injection drug use has resulted in a surge of new hepatitis C virus (HCV) infections. Approximately half of the people with HCV infection are unaware of their HCV status. Improving HCV awareness and increasing screening among people with OUD are critical. Addiction-Comprehensive Health Enhancement Support System (A-CHESS) is an evidence-based, smartphone-delivered relapse prevention system that has been implemented among people with OUD who are receiving medications for addiction treatment (MAT) to improve long-term recovery. Objective: We incorporated HCV-related content and functionality into A-CHESS to characterize the HCV care continuum among people in early remission and receiving MAT for OUD and to determine whether incorporating such content and functionality into A-CHESS increases HCV testing. Methods: HCV intervention content, including dissemination of educational information, private messages tailored to individuals' stage of HCV care, and a public discussion forum, was implemented into the A-CHESS platform. Between April 2016 and April 2020, 416 participants with OUD were enrolled in this study. Participants were randomly assigned to receive MAT alone (control arm) or MAT+A-CHESS (experimental arm). Quarterly telephone interviews were conducted from baseline to month 24 to assess risk behaviors and HCV testing history. Cox proportional hazards regression was used to assess whether participants who used A-CHESS were tested for HCV (either antibody [Ab] or RNA testing) at a higher rate than those in the control arm. To assess the effect of A-CHESS on subsets of participants at the highest risk for HCV, additional analyses were performed to examine the effect of the intervention among participants who injected drugs and shared injection equipment. Results: Overall, 44.2% (184/416) of the study participants were HCV Ab positive, 30.3% (126/416) were HCV Ab negative, and 25.5% (106/416) were considered untested at baseline. At month 24, there was no overall difference in HCV testing uptake between the intervention and control participants. However, among the subset of 109 participants who engaged in injection drug use, there was a slight trend toward increased HCV testing uptake among those who used A-CHESS (89% vs 85%; hazard ratio: 1.34; 95% CI 0.87-2.05; P =.18), and a stronger trend was observed when focusing on the subset of 32 participants who reported sharing injection equipment (87% vs 56%; hazard ratio: 2.92; 95% CI 0.959-8.86; P =.06). Conclusions: Incorporating HCV prevention and care information into A-CHESS may increase the uptake of HCV testing while preventing opioid relapse when implemented among populations who engage in high-risk behaviors such as sharing contaminated injection equipment. However, more studies that are powered to detect differences in HCV testing among high-risk groups are needed.

- Abstract
Background: Depressive symptoms are the most prevalent mental health concern among older adults (possibly heightened during the COVID-19 pandemic), which raises questions about how such symptoms can be lowered in this population. Existing research shows that offline social connectedness is a protective factor against depression in older adults; however, it is unknown whether web-based social connectedness can have similar effects. Objective: This study investigates whether social connectedness on a support website protects older adults against depressive symptoms over the course of a year, above and beyond the protective effect of offline social connectedness. The secondary aim is to determine whether older adults with increased depressive symptoms are more likely to engage in social connectedness on this website. Thus, we examine depressive symptoms as both an outcome and predictor of web-based social connectedness to fully understand the chain of causality among these variables. Finally, we compare web-based social connectedness with offline social connectedness in their ability to lower depressive symptoms among older adults. Methods: A total of 197 adults aged 65 years or older were given access to a social support website, where they were able to communicate with each other via a discussion forum for a year. Participants' social connectedness on the web-based platform, conceptualized as message production and consumption, was measured using behavioral log data as the number of messages participants wrote and read, respectively, during the first 6 months (t
1 ) and the following 6 months (t2 ) of the study. Participants self-reported their offline social connectedness as the number of people in their support networks, and they reported their depressive symptoms using the Patient Health Questionnaire-8 both at baseline (t1 ) and at 12-month follow-up (t2 ). To ascertain the flow of causality between these variables, we employed a cross-lagged panel design, in which all variables were measured at t1 and t2 . Results: After controlling for the effect of offline support networks at t1 , web-based message consumption at t1 decreased older adults' depressive symptoms at t2 (β =−.11; P =.02), but web-based message production at t1 did not impact t2 depressive symptoms (β =.12; P =.34). Web-based message consumption had a larger effect (β =−.11; P =.02) than offline support networks (β =−.08; P =.03) in reducing older adults' depressive symptoms over time. Higher baseline depressive symptoms did not predict increased web-based message consumption (β =.12; P =.36) or production (β =.02; P =.43) over time. Conclusions: The more messages older adults read on the web-based forum for the first 6 months of the study, the less depressed they felt at the 1-year follow-up, above and beyond the availability of offline support networks at baseline. This pinpoints the substantial potential of web-based communication to combat depressive symptoms in this vulnerable population.

Shah, Dhavan, Domke, David, and Wackman, Daniel
- Abstract
This study explores how “moral” issues interact with individuals' core values to influence the mental processes involved in choosing among candidates. Drawing upon three major domains of research - (1) construct activation and framing; (2) values and the self; and (3) decision making - we examine how individuals interpret electoral issues and the influence of these evaluations on the process of electoral choice. The same research design was used with three subpopulations - military reservists, ROTC student members, and undergraduate students - expected to be differentially involved with two issues in the study, abortion and gays in the military. Subjects were presented simulated newspaper articles about an election contest and asked to make a candidate choice. Findings indicate that an individual's interpretation of issues - as either ethical or material in nature - is strongly related to differences in the type of decision-making strategy used, even after accounting for a variety of demographic, orientational, and issue importance variables.

- Abstract
This study investigated the relationship between ethical and societal interpretations of issues and voters' decision-making strategies within systematically varied electoral issue environments. Analysis across two issue milieus using two measures of the decision-making process found that individuals who ascribed an ethical interpretation to issues were more likely to use a noncompensatory strategy, which focuses on one or two key issues in the decision-making process, than individuals who ascribed a societal interpretation to issues. This relationship held when the number of issues considered important and the importance placed on “social-moral” issues each were controlled.

Domke, David, Fan, David, Fibison, Michael, Shah, Dhavan, Smith, Steven, and Watts, Mark
- Abstract
There are two primary goals with this research. First, we examine whether news media were biased in coverage of the candidates or issues during the 1996 U.S. presidential campaign, as Republican Party candidate Bob Dole and others claimed. Second, we use an ideodynamic model of media effects to examine whether the quantity of positive and negative news coverage of the candidates was related to the public's preference of either Bill Clinton or Dole. The model posits that a candidate's level of support at any time is a function of the level of previous support (as measured in recent polls) plus changes in voters' preferences due to media coverage in the interim. This model allows exploration of whether news media coverage, alone, could predict the public's presidential preference in 1996. Using a computer content analysis program, 12,215 randomly sampled newspaper stories and television transcripts were examined from forty-three major media outlets from 10 March to 6 November 1996. Findings reveal both remarkably balanced media coverage of the two principal candidates, Clinton and Dole, and a powerful relationship between media coverage and public opinion.

Background: People who inject drugs are at a disproportionate risk for contracting hepatitis C virus (HCV). However, use of HCV prevention and treatment services remains suboptimal among people with substance use disorders due to various health system, societal, and individual barriers. Mobile health applications offer promising strategies to support people in recovery from substance use disorders. We sought to determine whether the Addiction-Comprehensive Health Enhancement Support System (A-CHESS), an existing mobile health application for opioid use disorder, could be adapted to improve HCV screening and treatment. Objective: The goals of this paper are to describe: (1) the components and functionality of an HCV intervention incorporated into the existing A-CHESS system; and (2) how data are collected and will be used to evaluate HCV testing, linkage to care, and treatment. Methods: People with recent opioid use were enrolled in a randomized controlled trial to test whether A-CHESS reduced relapse. We developed and implemented HCV intervention content within the A-CHESS platform to simultaneously evaluate whether A-CHESS improved secondary outcomes related to HCV care. All A-CHESS users received the HCV intervention content, which includes educational information, private messages tailored to an individual's stage of HCV care, and a public discussion forum. Data on patients' HCV risk behaviors and stage of care were collected through quarterly telephone interviews and weekly surveys delivered through A-CHESS. The proportion of people with opioid use disorder who are HCV untested, HCV-negative, HCV antibody-positive, or HCV RNA–positive, as well as linked to care, treated and cured at baseline is described here. The 24-month follow-up is ongoing and will be completed in April 2020. Survey data will then be used to assess whether individuals who received the HCV-enhanced A-CHESS intervention were more likely to reduce risky injection behaviors, receive HCV testing, link to medical care, initiate treatment, and be cured of HCV compared to the control group. Results: Between April 2016 and April 2018, 416 individuals were enrolled and completed the baseline interview. Of these individuals, 207 were then randomly assigned to the control arm and 209 were assigned to the intervention arm. At baseline, 202 individuals (49%) self-reported ever testing HCV antibody-positive. Of those, 179 (89%) reported receiving HCV RNA confirmatory testing, 134 (66%) tested HCV RNA–positive, 125 (62%) were linked to medical care and 27 (13%) were treated and cured of HCV. Of the remaining 214 individuals who had never tested HCV antibody–positive, 129 (31%) had tested HCV antibody–negative within the past year and 85 (20%) had not been tested within the past year. Conclusions: The A-CHESS mobile health system allows for the implementation of a bundle of services as well as the collection of longitudinal data related to drug use and HCV care among people with opioid use disorders. This study will provide preliminary evidence to determine whether HCV-specific services embedded into the A-CHESS program can improve HCV outcomes for people engaged in addiction treatment.

Background: Online discussion forums allow those in addiction recovery to seek help through text-based messages, including when facing triggers to drink or use drugs. Trained staff (or "moderators") may participate within these forums to offer guidance and support when participants are struggling but must expend considerable effort to continually review new content. Demands on moderators limit the scalability of evidence-based digital health interventions.Objective: Automated identification of recovery problems could allow moderators to engage in more timely and efficient ways with participants who are struggling. This paper aimed to investigate whether computational linguistics and supervised machine learning can be applied to successfully flag, in real time, those discussion forum messages that moderators find most concerning.Methods: Training data came from a trial of a mobile phone-based health intervention for individuals in recovery from alcohol use disorder, with human coders labeling discussion forum messages according to whether or not authors mentioned problems in their recovery process. Linguistic features of these messages were extracted via several computational techniques: (1) a Bag-of-Words approach, (2) the dictionary-based Linguistic Inquiry and Word Count program, and (3) a hybrid approach combining the most important features from both Bag-of-Words and Linguistic Inquiry and Word Count. These features were applied within binary classifiers leveraging several methods of supervised machine learning: support vector machines, decision trees, and boosted decision trees. Classifiers were evaluated in data from a later deployment of the recovery support intervention.Results: To distinguish recovery problem disclosures, the Bag-of-Words approach relied on domain-specific language, including words explicitly linked to substance use and mental health ("drink," "relapse," "depression," and so on), whereas the Linguistic Inquiry and Word Count approach relied on language characteristics such as tone, affect, insight, and presence of quantifiers and time references, as well as pronouns. A boosted decision tree classifier, utilizing features from both Bag-of-Words and Linguistic Inquiry and Word Count performed best in identifying problems disclosed within the discussion forum, achieving 88% sensitivity and 82% specificity in a separate cohort of patients in recovery.Conclusions: Differences in language use can distinguish messages disclosing recovery problems from other message types. Incorporating machine learning models based on language use allows real-time flagging of concerning content such that trained staff may engage more efficiently and focus their attention on time-sensitive issues.

Background: Despite the near ubiquity of mobile phones, little research has been conducted on the implementation of mobile health (mHealth) apps to treat patients in primary care. Although primary care clinicians routinely treat chronic conditions such as asthma and diabetes, they rarely treat addiction, a common chronic condition. Instead, addiction is most often treated in the US health care system, if it is treated at all, in a separate behavioral health system. mHealth could help integrate addiction treatment in primary care.Objective: The objective of this paper was to report the effects of implementing an mHealth system for addiction in primary care on both patients and clinicians.Methods: In this implementation research trial, an evidence-based mHealth system named Seva was introduced sequentially over 36 months to a maximum of 100 patients with substance use disorders (SUDs) in each of three federally qualified health centers (FQHCs; primary care clinics that serve patients regardless of their ability to pay). This paper reports on patient and clinician outcomes organized according to the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework.Results: The outcomes according to the RE-AIM framework are as follows: Reach-Seva reached 8.31% (268/3226) of appropriate patients. Reach was limited by our ability to pay for phones and data plans for a maximum of 100 patients per clinic. Effectiveness-Patients who were given Seva had significant improvements in their risky drinking days (44% reduction, (0.7-1.25)/1.25, P=.04), illicit drug-use days (34% reduction, (2.14-3.22)/3.22, P=.01), quality of life, human immunodeficiency virus screening rates, and number of hospitalizations. Through Seva, patients also provided peer support to one another in ways that are novel in primary care settings. Adoption-Patients sustained high levels of Seva use-between 53% and 60% of the patients at the 3 sites accessed Seva during the last week of the 12-month implementation period. Among clinicians, use of the technology was less robust than use by patients, with only a handful of clinicians using Seva in each clinic and behavioral health providers making most referrals to Seva in 2 of the 3 clinics. Implementation-At 2 sites, implementation plans were realized successfully; they were delayed in the third. Maintenance-Use of Seva dropped when grant funding stopped paying for the mobile phones and data plans. Two of the 3 clinics wanted to maintain the use of Seva, but they struggled to find funding to support this.Conclusions: Implementing an mHealth system can improve care among primary care patients with SUDs, and patients using the system can support one another in their recovery. Among clinicians, however, implementation requires figuring out how information from the mHealth system will be used and making mHealth data available in the electronic health (eHealth) record. In addition, paying for an mHealth system remains a challenge. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Building upon the vast compilation of academic work that has risen from the theory of social capital, this paper seeks to further explore two concepts central to this strand of research: social and interpersonal trust. A primary goal of this project is to emphasize the theoretical differences between these two types of trust âa distinction that has been blurred in past workâ and to empirically demonstrate that social trust of an abstract collective other is significantly different from interpersonal forms of trust that are derived from more direct, personal interactions. Analysis of data collected from a large, national survey sample suggests that social and interpersonal trust have unique relationships with a host of situational and social orientation variables. Results from this study also reveal that the relationship between local television news use and various forms of trust is not uniform, but variable and nuanced. The ability for social orientation variables, such as community attachment, interpersonal communication, and informal socializing, to act as moderators that enhance the relationship between local television news attention and certain types of trust is also documented. On a larger scope, the results of this study suggest that it might be useful to continue to include multiple measures of interpersonal trust in studies that seek to uncover relationships between media use and participatory outcomes. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]

Background: Symptom distress in patients toward the end of life can change rapidly. Family caregivers have the potential to help patients manage those symptoms, as well as their own stress, if they are equipped with the proper resources. Electronic health (eHealth) systems may be able to provide those resources. Very sick patients may not be able to use such systems themselves to report their symptoms but family caregivers could.Objective: The aim of this paper was to assess the effects on cancer patient symptom distress of an eHealth system that alerts clinicians to significant changes in the patient's symptoms, as reported by a family caregiver.Methods: A pooled analysis from two randomized clinical trials (NCT00214162 and NCT00365963) compared outcomes at 12 months for two unblinded groups: a control group (Comprehensive Health Enhancement Support System [CHESS]-Only) that gave caregivers access to CHESS, an online support system, and an experimental group (CHESS+CR [Clinician Report]), which also had CHESS but with a CR that automatically alerted clinicians if symptoms exceeded a predetermined threshold of severity. Participants were dyads (n=235) of patients with advanced lung, breast, or prostate cancer and their respective family caregivers from 5 oncology clinics in the United States of America. The proportion of improved patient threshold symptoms was compared between groups using area-under-the-curve analysis and binomial proportion tests. The proportion of threshold symptoms out of all reported symptoms was also examined.Results: When severe caregiver-reported symptoms were shared with clinicians, the symptoms were more likely to be subsequently reported as improved than when the symptoms were not shared with clinicians (P<.001). Fewer symptom reports were completed in the group of caregivers whose reports went to clinicians than in the CHESS-Only group (P<.001), perhaps because caregivers, knowing their reports might be sent to a doctor, feared they might be bothering the clinician.Conclusions: This study suggests that an eHealth system designed for caregivers that alerts clinicians to worrisome changes in patient health status may lead to reduced patient distress.Trial Registration: Clinicaltrials.gov NCT00214162; https://clinicaltrials.gov/ct2/show/NCT00214162 (Archived by WebCite at http://www.webcitation.org/6nmgdGfuD) and Clinicaltrials.gov NCT00365963; https://clinicaltrials.gov/ct2/show/NCT00365963 (Archived by WebCite at http://www.webcitation.org/6nmh0U8VP).

This study examines the relationship between perceived social support and emotional well-being when predicting various types of information seeking behaviors of breast cancer patients in the Comprehensive Health Enhancement Support System (CHESS)—a well-established ICCS. The findings revealed that women with breast cancer sought out more health-related information when they perceived low levels of social support than high levels of social support. Also, the negative relationship between perceived social support and different information seeking behaviors - Total Information Service, Experiential Information Service, and Psychosocial Topic Use - was greater for those who reported high levels of emotional well-being than those who experienced low levels of emotional well-being. Regarding specific topic use, patients with low levels of social support and high sense of emotional well-being used psychosocial information the most as a way to compensate the deficiency in social networks. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]

This study examines the effects of exchanging treatment information within computer-mediated breast cancer support groups on emotional well-being, and explores whether this relationship is moderated by health self-efficacy. To test the hypotheses, analysis of data was conducted on 177 breast cancer patients using an eHealth program with discussion group. Findings suggest the effects of expression and reception of treatment information on emotional well-being are significantly greater for those who have higher health self-efficacy. These results conditionally support prior research finding positive effects of treatment information exchanges among breast cancer patients. Such exchanges had a positive impact on emotional well-being for those with higher health self-efficacy, but they had a negative influence for those with lower health self-efficacy. Given that the benefits of exchanging treatment information in CMSS are conditioned by health self-efficacy, clinicians should especially encourage use of e-health systems among those with higher self-efficacy regarding their disease. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]

Social support in computer-mediated setting is an important variable in health communication research, yet little is known about the factors that influence the amount of social support one gives and receives within online support groups. To shed some light on this issue, we examined demographics, disease-related factors, psychosocial factors, and strategies for coping with breast cancer as potential determinants of which patients provide support to others and which ones receive it. Data collected from 177 participants in an online discussion group revealed that those who are younger, have higher levels of positive reframing, and lower levels of self-blame are more likely to provide emotional support. In contrast, those who are more educated, have less existing social support, and have lower levels of religious coping are more likely to receive emotional support from others. The practical implications for providing effective psychosocial support for women with breast cancer are discussed. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]

Past studies on the efficacy of participation in online cancer support groups have primarily focused on the role of expression in the accrual of health benefits for participants. Unfortunately, few steps have been taken to determine whether this observed effect arises solely from the internal mental processes underlying the act of expressing or, perhaps, owes something to a nuanced, multi-dimensional understanding of expression which includes reception of responses to what is expressed. To test for the multi-layered effect, we attend to one of the key concepts in the online support community scholarship: Empathy. Our findings suggest that it is a combination of empathy expression and reception that is crucial to attaining optimal benefits for cancer patients. Further, our finding supports the buffering hypothesis that empathic expression provides a salutary effect for patients who experienced a higher degree of concern associated with their cancer diagnosis and follow-up treatments. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]

Numerous studies have investigated the effect of Interactive Cancer Communication Systems (ICCSs) on cancer patients or caregivers' health benefits. Research in this area, however, has focused mostly on the direct effects of an ICCS on positive health outcomes, rather than the psychological mechanism of the ICCS effect. This study examines the effect of perceived caregiver bonding in an ICCS (the Comprehensive Health Enhancement Support System, CHESS) on caregivers' coping strategies, assuming that perceived bonding is one of the core curative factors that result from using an ICCS. 246 caregivers were randomly assigned to either the Internet with links to high-quality lung cancer websites or access to CHESS, which integrated information, communication and interactive coaching tools. Findings suggest that the perceived bonding has positive impacts on caregivers' appraisal and problem-focused coping strategies, and it mediates the effect of ICCS on the coping strategies 6 months after the intervention began. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]

The effects tradition in mass communication has faced considerable criticism, with questions directed at the epistemological and ontological basis of tracing the influence of media. Political communication research has not addressed these critiques as well as it might, with too many scholars relying on ecologically invalid experimental studies or structural equation modeling of cross-sectional data as the basis for making claims about effects. I contend that a focus on explaining processes should displace a concern with predicting outcomes, though this shift need not mean abandoning the concept of effects. Instead, advances in methods, design, and analysis have put communication researchers, especially those concerned with politics, in a unique position to examine media influence. More complex experimental studies, multi-wave panel surveys, and full network studies of reception and expression are adding to the field's ability to explore actual and perceived effects of mass media. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]

In this paper, we contend that youth engagement - both in the form of civic behaviors such as volunteering and organizational memberships and more overtly political behaviors such as political expression and campaign participation - is critical to early adulthood socialization, and the accompanying responsibilities of citizenship (McLeod, 2000). However, we question whether media - television, campaign ads, and the Internet - are culprits reducing participation, contending instead that certain forms of mass media use may be agents of socialization into civic and political engagement. As a robust test of these relationships, we conducted two multimethod studies of campaign communication effects. Our studies merged campaign advertising placement and content data on a community-by-community basis during the 2000 and 2004 U.S. presidential election seasons with two national panel surveys conducted during these elections. We then run separate models of younger and older adults' civic and political participation during these two election seasons. Findings reveal that campaign effects on younger and older generations are mediated through information seeking and citizen expression about politics to encourage civic and political engagement. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]

Serious decline of media trust are thought to represent widespread cynicism in American political culture, which results in citizens' withdrawal from political activities as well as their political inefficacy. However, the linkages between media distrust and decreased political participation might not be self-evident. Rather, citizens' media distrust may in some part represent healthy skepticism which is related to citizens' active political participation through their effortful information search and exchange. These ideas are tested with a national survey data on 2004 presidential election. Findings show that media distrust was positively related to citizens' online information seeking and offline political discussion, which, in turn, affected their diverse campaign participations. These effects of media distrust appear to be channeled through citizens' communicative participation such as online information search and face-to-face political discussion which then facilitate citizens' political activities. ..PAT.-Unpublished Manuscript [ABSTRACT FROM AUTHOR]

47. How can research keep up with eHealth? Ten strategies for increasing the timeliness and usefulness of eHealth research.

- Abstract
Background: eHealth interventions appear and change so quickly that they challenge the way we conduct research. By the time a randomized trial of a new intervention is published, technological improvements and clinical discoveries may make the intervention dated and unappealing. This and the spate of health-related apps and websites may lead consumers, patients, and caregivers to use interventions that lack evidence of efficacy.Objective: This paper aims to offer strategies for increasing the speed and usefulness of eHealth research.Methods: The paper describes two types of strategies based on the authors' own research and the research literature: those that improve the efficiency of eHealth research, and those that improve its quality.Results: Efficiency strategies include: (1) think small: conduct small studies that can target discrete but significant questions and thereby speed knowledge acquisition; (2) use efficient designs: use such methods as fractional-factorial and quasi-experimental designs and surrogate endpoints, and experimentally modify and evaluate interventions and delivery systems already in use; (3) study universals: focus on timeless behavioral, psychological, and cognitive principles and systems; (4) anticipate the next big thing: listen to voices outside normal practice and connect different perspectives for new insights; (5) improve information delivery systems: researchers should apply their communications expertise to enhance inter-researcher communication, which could synergistically accelerate progress and capitalize upon the availability of "big data"; and (6) develop models, including mediators and moderators: valid models are remarkably generative, and tests of moderation and mediation should elucidate boundary conditions of effects and treatment mechanisms. Quality strategies include: (1) continuous quality improvement: researchers need to borrow engineering practices such as the continuous enhancement of interventions to incorporate clinical and technological progress; (2) help consumers identify quality: consumers, clinicians, and others all need to easily identify quality, suggesting the need to efficiently and publicly index intervention quality; (3) reduce the costs of care: concern with health care costs can drive intervention adoption and use and lead to novel intervention effects (eg, reduced falls in the elderly); and (4) deeply understand users: a rigorous evaluation of the consumer's needs is a key starting point for intervention development.Conclusions: The challenges of distinguishing and distributing scientifically validated interventions are formidable. The strategies described are meant to spur discussion and further thinking, which are important, given the potential of eHealth interventions to help patients and families.

- Abstract
Background Emotional support has traditionally been conceived as something a breast cancer patient receives. However, this framework may obscure a more complex process, facilitated by the emerging social media environment, which includes the effects of composing and sending messages to others. Accordingly, this study explores the effects of expression and reception of emotional support messages in online groups and the importance of bonding as a mediator influencing the coping strategies of breast cancer patients.Methods Data were collected as part of two National Cancer Institute–funded randomized clinical trials. Eligible subjects were within 2 months of diagnosis of primary breast cancer or recurrence. Expression and reception of emotionally supportive messages were tracked and coded for 237 breast cancer patients. Analysis resulted from merging 1) computer-aided content analysis of discussion posts, 2) action log analysis of system use, and 3) longitudinal survey data.Results As expected, perceived bonding was positively related to all four coping strategies (active coping: β = 0.251, P = .000; positive reframing: β = 0.288, P = .000; planning: β = 0.213, P = .006; humor: β = 0.159, P = .009). More importantly, expression (γ = 0.138, P = .027), but not reception (γ = −0.018, P = .741), of emotional support increases perceived bonding, which in turn mediates the effects on patients’ positive coping strategies.Conclusions There is increasing importance for scholars to distinguish the effects of expression from reception to understand the processes involved in producing psychosocial benefits. This study shows that emotional support is more than something cancer patients receive; it is part of an active, complex process that can be facilitated by social media.- Published
