Internet-based health information consumer skills intervention for people living with HIV/AIDS

When Experts Offer Conflicting Information: A Study of Perceived Ambiguity, Information Insufficiency, Trustworthiness and Risk Information Behaviors

This study conducted an experiment to examine the impact of informational conflicts about COVID-19 transmission routes on cognitive and behavioral factors. We were guided by the risk information seeking and processing model and focused on relationships among perceived ambiguity, information insufficiency, trustworthiness, and seeking/avoidance across several conditions. Data from 304 participants indicated a higher level of perceived ambiguity in the conflicting information condition compared to the one-sided information condition. The serial mediations suggest conflicting information enhanced perceived ambiguity, which was negatively related with trustworthiness of experts, information seeking, and adherence intentions. These findings shed light on how conflicting information negatively affects the decision-making process and provide insight about what to consider when presenting dynamic information to the public.

Interventions for improving health literacy in migrants

BACKGROUND

Health literacy (HL) is a determinant of health and important for autonomous decision-making. Migrants are at high risk for limited HL. Improving HL is important for equitable promotion of migrants' health.

OBJECTIVES

To assess the effectiveness of interventions for improving HL in migrants. To assess whether female or male migrants respond differently to the identified interventions.

SEARCH METHODS

We ran electronic searches to 2 February 2022 in CENTRAL, MEDLINE, Embase, PsycInfo and CINAHL. We also searched trial registries. We used a study filter for randomised controlled trials (RCTs) (RCT classifier).

SELECTION CRITERIA

We included RCTs and cluster-RCTs addressing HL either as a concept or its components (access, understand, appraise, apply health information).

DATA COLLECTION AND ANALYSIS

We used the methodological procedures recommended by Cochrane and followed the PRISMA-E guidelines. Outcome categories were: a) HL, b) quality of life (QoL), c) knowledge, d) health outcomes, e) health behaviour, f) self-efficacy, g) health service use and h) adverse events. We conducted meta-analysis where possible, and reported the remaining results as a narrative synthesis.

MAIN RESULTS

We included 28 RCTs and six cluster-RCTs (8249 participants), all conducted in high-income countries. Participants were migrants with a wide range of conditions. All interventions were adapted to culture, language and literacy. We did not find evidence that HL interventions cause harm, but only two studies assessed adverse events (e.g. anxiety). Many studies reported results for short-term assessments (less than six weeks after total programme completion), reported here. For several comparisons, there were also findings at later time points, which are presented in the review text. Compared with no HL intervention (standard care/no intervention) or an unrelated HL intervention (similar intervention but different information topic) Self-management programmes (SMP) probably improve self-efficacy slightly (standardised mean difference (SMD) 0.28, 95% confidence interval (CI) 0.06 to 0.50; 2 studies, 333 participants; moderate certainty). SMP may improve HIV-related HL (understanding (mean difference (MD) 4.25, 95% CI 1.32 to 7.18); recognition of HIV terms (MD 3.32, 95% CI 1.28 to 5.36)) (1 study, 69 participants). SMP may slightly improve health behaviours (3 studies, 514 participants), but may have little or no effect on knowledge (2 studies, 321 participants) or subjective health status (MD 0.38, 95% CI -0.13 to 0.89; 1 study, 69 participants) (low certainty). We are uncertain of the effects of SMP on QoL, health service use or adverse events due to a lack of evidence. HL skills building courses (HLSBC) may improve knowledge (MD 10.87, 95% CI 5.69 to 16.06; 2 studies, 111 participants) and any generic HL (SMD 0.48, 95% CI 0.20 to 0.75; 2 studies, 229 participants), but may have little or no effect on depression literacy (MD 0.17, 95% CI -1.28 to 1.62) or any health behaviour (2 studies, 229 participants) (low certainty). We are uncertain if HLSBC improve QoL, health outcomes, health service use, self-efficacy or adverse events, due to very low-certainty or a lack of evidence. Audio-/visual education without personal feedback (AVE) probably improves depression literacy (MD 8.62, 95% CI 7.51 to 9.73; 1 study, 202 participants) and health service use (MD -0.59, 95% CI -1.11 to -0.07; 1 study, 157 participants), but probably has little or no effect on health behaviour (risk ratio (RR) 1.07, 95% CI 0.91 to 1.25; 1 study, 135 participants) (moderate certainty). AVE may improve self-efficacy (MD 3.51, 95% CI 2.53 to 4.49; 1 study, 133 participants) and may slightly improve knowledge (MD 8.44, 95% CI -2.56 to 19.44; 2 studies, 293 participants) and intention to seek depression treatment (MD 1.8, 95% CI 0.43 to 3.17), with little or no effect on depression (SMD -0.15, 95% CI -0.40 to 0.10) (low certainty). No evidence was found for QoL and adverse events. Adapted medical instruction may improve understanding of health information (3 studies, 478 participants), with little or no effect on medication adherence (MD 0.5, 95% CI -0.1 to 1.1; 1 study, 200 participants) (low certainty). No evidence was found for QoL, health outcomes, knowledge, health service use, self-efficacy or adverse events. Compared with written information on the same topic SMP probably improves health numeracy slightly (MD 0.7, 95% CI 0.15 to 1.25) and probably improves print literacy (MD 9, 95% CI 2.9 to 15.1; 1 study, 209 participants) and self-efficacy (SMD 0.47, 95% CI 0.3 to 0.64; 4 studies, 552 participants) (moderate certainty). SMP may improve any disease-specific HL (SMD 0.67, 95% CI 0.27 to 1.07; 4 studies, 955 participants), knowledge (MD 11.45, 95% CI 4.75 to 18.15; 6 studies, 1101 participants) and some health behaviours (4 studies, 797 participants), with little or no effect on health information appraisal (MD 1.15, 95% CI -0.23 to 2.53; 1 study, 329 participants) (low certainty). We are uncertain whether SMP improves QoL, health outcomes, health service use or adverse events, due to a lack of evidence or low/very low-certainty evidence. AVE probably has little or no effect on diabetes HL (MD 2, 95% CI -0.15 to 4.15; 1 study, 240 participants), but probably improves information appraisal (MD -9.88, 95% CI -12.87 to -6.89) and application (RR 1.51, 95% CI 1.29 to 1.77) (1 study, 608 participants; moderate certainty). AVE may slightly improve knowledge (MD 8.35, 95% CI -0.32 to 17.02; low certainty). No short-term evidence was found for QoL, depression, health behaviour, self-efficacy, health service use or adverse events. AVE compared with another AVE We are uncertain whether narrative videos are superior to factual knowledge videos as the evidence is of very low certainty. Gender differences Female migrants' diabetes HL may improve slightly more than that of males, when receiving AVE (MD 5.00, 95% CI 0.62 to 9.38; 1 study, 118 participants), but we do not know whether female or male migrants benefit differently from other interventions due to very low-certainty or a lack of evidence.

AUTHORS' CONCLUSIONS

Adequately powered studies measuring long-term effects (more than six months) of HL interventions in female and male migrants are needed, using well-validated tools and representing various healthcare systems.

The effect of digital interventions on related health literacy and skills for individuals living with chronic diseases: A systematic review and meta-analysis

BACKGROUND

Chronic diseases are a leading cause of death and disease burden globally. Digital interventions could be an approach to improve patients' ability to find, evaluate, and use health information.

OBJECTIVES

The main objective was to conduct a systematic review to determine the effect of digital interventions on digital health literacy for patients living with chronic disease. Secondary objectives were to provide an overviewof the design and delivery characteristics of interventions that impact digital health literacy in people with chronic disease.

METHODS

Randomized controlled trials examining digital health literacy (and related components) for individuals with cardiovascular disease, chronic lung disease, osteoarthritis, diabetes, chronic kidney disease, and HIV were identified. This review was conducted following the PRIMSA guidelines. Certainty was assessed using GRADE and the Cochrane risk of bias tool. Meta-analyses were conducted using Review Manager 5.1. The protocol was registered on PROSPERO (CRD42022375967).

RESULTS

9386 articles were identified and 17 articles representing 16 unique trials were included. Studies evaluated 5138 individuals with one or more chronic conditions (50% women, ages 42 ± 7-71 ± 12 years). The most targeted conditions were cancer, diabetes, cardiovascular disease, and HIV. Interventions included: skills training, websites, electronic personal health records, remote patient monitoring, and education. The effects of the interventions were related to: (i) digital health literacy, (ii) health literacy, (iii) health information skills, (iv) technology skills and access, and (v) self-management and participation in care. A meta-analysis of three studies identified the effect of digital interventions was better than usual care for eHealth literacy (1.22 [CI 0.55, 1.89], p < 0.001).

CONCLUSIONS

The evidence of the effects of digital interventions on related health literacy is limited. Existing studies reflect the heterogeneity in study design, population, and outcome measures. There is a need for further studies on the effects of digital interventions on related health literacy for individuals with chronic conditions.

Evaluation of the health promotion effect of hepatitis B prevention and treatment in the Zhejiang demonstration area, China

Background

To investigate the health literacy level and health promotion effect of hepatitis B prevention and treatment in the demonstration area of Zhejiang Province.

Methods

The National Science and Technology Major Health Education Group took 6 demonstration areas in Zhejiang Province as the whole research site. After the sample size (N=2160 people) was determined, a multistage stratified cluster sampling method was used to conduct a questionnaire survey in 2018 (before health education) and 2019 (after health education). Stata 12 statistical software was used to analyse the status and improvement rate of hepatitis B health literacy of residents in the demonstration area before and after health education and compare the health promotion effects of different health intervention methods.

Results

Before and after health education, there was no significant difference in the basic information of the subjects (P>0.05). After the health education intervention, the level of hepatitis B health literacy of residents in the demonstration area increased by 11.8%, and the difference was statistically significant (P < 0.001). The awareness rate of hepatitis B transmission was low before health education but increased after health education. The form of "Internet +" health education may better improve the residents' health literacy level about hepatitis B prevention and treatment.

Conclusion

After health education, the level of health literacy of residents in the Zhejiang demonstration area about hepatitis B prevention and control significantly improved, but there is room for further improvement. In the future, targeted health education intervention should be carried out, and the health education mode of "Internet +" can achieve better results to effectively prevent and control hepatitis B.

From physician’s authority to patient expertise: the effects of e-health technology use on patient’s behavior and physician-patient relationship

Purpose

This paper aims to examine the health technology use in health information seeking, communication and personal health information management, as well as in the effects they may have on his relationship with the physician and on the consumption of medical resources.

Design/methodology/approach

An online survey was conducted. The questionnaires were distributed via online health discussion forums using Google's survey software with a summary presentation of the study’s objective. The final selection of 362 individuals was made using social media, direct email and collaboration with community groups. The empirical validation of the causal model was conducted using the partial least square approach.

Findings

The results show that the use of e-health strengthens the quality of the patient–physician relationship and patient empowerment while increasing the consumption of medical resources.

Originality/value

The results of this research indicate that the internet has transformed the relationship of patients to health, to their doctors and to the health-care system. In this new context, a reconsideration of the status of the patient must be considered by health service providers.

Uptake of and Engagement With an Online Sexual Health Intervention (HOPE eIntervention) Among African American Young Adults: Mixed Methods Study

Background

Regarding health technologies, African American young adults have low rates of uptake, ongoing usage, and engagement, which may widen sexual health inequalities.

Objective

We aimed to examine rates of uptake and ongoing usage, and factors influencing uptake, ongoing usage, and engagement for a consumer health informatics (CHI) intervention for HIV/sexually transmitted infection (STI) prevention among African American young adults, using the diffusion of innovation theory, trust-centered design framework, and O’Brien and Toms’ model of engagement.

Methods

This community-based participatory mixed methods study included surveys at four time points (n=315; 280 African American participants) among young adults aged 18 to 24 years involved in a blended offline/online HIV/STI prevention intervention (HIV Outreach, Prevention, and Education [HOPE] eIntervention), which was described as a “HOPE party.” Qualitative interviews were conducted with a subset of participants (n=19) after initial surveys and website server logs indicated low uptake and ongoing usage. A generalized linear mixed-effects model identified predictors of eIntervention uptake, server logs were summarized to describe use over time, and interview transcripts were coded and thematically analyzed to identify factors affecting uptake and engagement.

Results

Participants’ initial self-reported eIntervention uptake was low, but increased significantly over time, although uptake never reached expectations. The most frequent activity was visiting the website. Demographic factors and HOPE party social network characteristics were not significantly correlated with uptake, although participant education and party network gender homophily approached significance. According to interviews, one factor driving uptake was the desire to share HIV/STI prevention information with others. Survey and interview results showed that technology access, perceived time, and institutional and technological trust were necessary conditions for uptake. Interviews revealed that factors undermining uptake were insufficient promotion and awareness building, and the platform of the intervention, with social media being less appealing due to previous negative experiences concerning discussion of sexuality on social media. During the interaction with the eIntervention, interview data showed that factors driving initial engagement were audience-targeted website esthetics and appealing visuals. Ongoing usage was impeded by insufficiently frequent updates. Similarly, lack of novelty drove disengagement, although a social media contest for sharing intervention content resulted in some re-engagement.

Conclusions

To encourage uptake, CHI interventions for African American young adults can better leverage users’ desires to share information about HIV/STI prevention with others. Ensuring implementation through trusted organizations is also important, though vigorous promotion is needed. Visual appeal and targeted content foster engagement at first, but ongoing usage may require continual content changes. A thorough analysis of CHI intervention use can inform the development of future interventions to promote uptake and engagement. To guide future analyses, we present an expanded uptake and engagement model for CHI interventions targeting African American young adults based on our empirical results.

Effects of health literacy interventions on health-related outcomes in socioeconomically disadvantaged adults living in the community: a systematic review

OBJECTIVES

The objectives of this review were: i) to identify and synthesize the best available evidence on the effectiveness on health-related outcomes of health literacy interventions for enabling socioeconomically disadvantaged people living in the community to access, understand, appraise and apply health information; and ii) to identify components of health literacy interventions associated with improved health-related outcomes.

INTRODUCTION

Health literacy is defined as a person's competence in accessing, understanding, appraising and applying health information in order to make sound health decisions. A high level of health literacy is positively related to better health outcomes. However, nearly half of the American and European populations have low health literacy levels. Socioeconomically disadvantaged groups in particular present with the weakest health literacy levels, suggesting that differences in health literacy levels contribute to health disparities. Therefore, there is a need to understand the conditions under which health literacy interventions aiming at improving health-related outcomes among socioeconomically disadvantaged people can be implemented.

INCLUSION CRITERIA

This review considered studies on socioeconomically disadvantaged adults living in the community identified using the socially stratifying PROGRESS factors (Place of residence, Race/ethnicity, Occupation, Gender, Religion, Education, Socioeconomic status, Social capital).This review considered studies evaluating the following interventions: i) targeting health literacy based on either a clinical and/or a public health approach, ii) delivered at the individual, interpersonal, community or societal level, iii) delivered by any healthcare/social work professional, and iv) using a single or multicomponent strategy. The comparator was no treatment, standard care or a variation of the intervention. All randomized and non-randomized controlled trials as well as quasi-experimental designs were included. Outcomes considered were: i) health-related quality of life and health-related outcomes, ii) health behavior outcomes, and iii) outcomes related to the access and use of healthcare services.

METHODS

A three-step strategy was conducted for primary research published up to May 2018 across seven databases without any language restriction. A search for gray literature was also conducted. Titles and abstracts were screened for assessment against the inclusion criteria. Studies that met the inclusion criteria were retrieved in full and then assessed in detail against the inclusion criteria. Critical appraisal was undertaken using the standardized critical appraisal instruments from JBI. Data were extracted from included studies using standardized data extraction tools from JBI. A meta-analysis was not possible; findings have been presented in a narrative form.

RESULTS

Twenty-one studies were included in the review. Three studies addressed the health literacy competency of understanding health information, and 18 addressed the competency of applying health information. Thirteen studies were found as effective based on a variety of health-related outcomes (mainly clinical outcomes), preventive health practices and behaviors, and health-promoting behaviors. Results enabled identification of some effective intervention operational components, including cultural appropriateness, tailoring, skills building, goal setting and active discussions. Multi-faceted interventions, combining both an information transfer medium and contact with an interventionist, appear to be more effective than single modality interventions. The use of an appropriate theoretical foundation is also an important factor for successful interventions.

CONCLUSION

To improve health-related outcomes among socioeconomically disadvantaged people, health literacy interventions are more likely to be successful if they are theory-based, are multi-faceted and use person-centered operational components such as cultural appropriateness, tailoring, skills building, goal setting and active discussions.

Talk to Your Doctors Online: An Internet-based Intervention in China

China has long faced the problem of having health care that is difficult to access. Online patient-provider communication (OPPC) may offer a new option for the delivery of affordable health services in a timely manner. However, OPPC is still novel in China, particularly among middle-aged and older adults. Thus, to promote effective use of OPPC for these population groups, the current study implemented a four-week Internet-based intervention program, with a general basis of Social Cognitive Theory. With analyses of three-wave panel data, the results offer the promise of this intervention program in increasing usage frequency, quality of users' experience, self-efficacy, behavioral capability, and awareness of OPPC. This Internet-based intervention program also provides important implications for future research, practice, and policy in promoting e-Health in China.

Interventions to support consumer evaluation of online health information credibility: A scoping review

PURPOSE

Various interventions have been designed to help consumers better evaluate the credibility of online health information (OHI). However, assessing information credibility remained the most widely reported challenge by online health consumers. This review aims to provide an overview of major intervention approaches for improving consumer ability to evaluate OHI credibility in order to identify opportunities for future interventions.

METHODS

A scoping review was performed. Seven relevant scientific databases were searched to identify articles that report the design and/or evaluation of interventions to support, facilitate, or assist consumers in assessing the credibility of OHI. Thirty-one articles met the inclusion criteria. Relevant content was extracted from the articles and all codes were validated by second coders.

RESULTS

Three major intervention approaches for enhancing consumers' ability to evaluate OHI credibility were identified: educational program, algorithm, and interactive interface. The design of most interventions (particularly the credibility evaluation component) lacked the guidance of theories, and very few studies systematically evaluated their effectiveness in real online search contexts. Few interventions can provide spontaneous support to consumers while they search online.

CONCLUSION

Our understanding of what theoretical constructs contribute to effective OHI credibility evaluation interventions and how intervention outcomes should be measured remained limited. Future efforts need to focus on the design, development, test, and evaluation of theory-guided OHI credibility evaluation interventions that are scalable, sustainable, and can provide real-time support to consumers.

How Does Online Patient-Provider Communication Heal? Examining the Role of Patient Satisfaction and Communication Experience in China

China is facing the problem of having health care that is difficult to access. Online patient-provider communication (OPPC) may bring a new option to deliver health services. However, online communication with doctors is still novel to many people in China. Little research has been conducted to examine how OPPC could improve health outcomes. With an integrated model that incorporates social cognitive theory into the three-stage model of health promotion using interactive media, this study tested the social mechanism underlying the impact of OPPC. Results indicated that self-efficacy, behavioral capability, and outcome expectation positively predicted OPPC at Stage 1, which in turn increased patient satisfaction at Stage 2, which finally improved three types of health outcomes (general, emotional, and physical) at Stage 3. In addition, quality of users' experience in OPPC positively moderated this mediation pathway. Theoretical and practical implications of this study were also discussed.

Deaf Adults' Health Literacy and Access to Health Information: Protocol for a Multicenter Mixed Methods Study

Background

Deaf American Sign Language (ASL) users often struggle with limited health literacy compared with their hearing peers. However, the mechanisms driving limited health literacy and how this may impact access to and understanding of health information for Deaf individuals have not been determined. Deaf individuals are more likely than hearing individuals to use the internet, yet they continue to report significant barriers to health information. This study presents an opportunity to identify key targets that impact information access for a largely marginalized population.

Objective

This study aims to elucidate the role of information marginalization on health literacy in Deaf ASL users and to better understand the mechanisms of health literacy in this population for the purpose of identifying viable targets for future health literacy interventions.

Methods

This is an exploratory mixed methods study to identify predictors and moderators of health literacy in the Deaf population. These predictors of health literacy will be used to inform the second step that qualitatively explains the findings, including how Deaf individuals access and understand Web-based health information. Multiple interviewer- and computer-based instruments underwent translation and adaptation, from English to ASL, to make them accessible for the Deaf participants in our study. A planned sample of 450 Deaf ASL users and 450 hearing native English speakers, aged 18 to 70 years, will be recruited from 3 partnering sites: Rochester, NY; Flint, MI; and Chicago, IL. These individuals will participate in a single data collection visit. A subset of participants (approximately 30) with key characteristics of interest will be invited for a second data collection visit to observe and inquire more about their ability to directly access, navigate, and comprehend Web-based health information. The study will help assess how the ways health literacy and information are visualized may differ between Deaf individuals and hearing individuals. The study will also survey participants’ ownership and use of computer and mobile devices and their level of Web-based information use, including health information.

Results

Adaptation and translation of protocols and instruments have been completed and are now in use for the study. Recruitment is underway and will continue until late 2020. Results from this study will be used to provide a guide on how to structure Web-based health information in a way that maximizes accessibility and improves health literacy for Deaf individuals.

Conclusions

The results from this mixed methods proposal will advance what is known about health literacy and health information accessibility for Deaf individuals. This innovative study will generate rich data on how to formulate health information and health literacy interventions more accurately to take advantage of visual learning skills.

Changing behaviour 'more or less'-do theories of behaviour inform strategies for implementation and de-implementation? A critical interpretive synthesis

BACKGROUND

Implementing evidence-based care requires healthcare practitioners to do less of some things (de-implementation) and more of others (implementation). Variations in effectiveness of behaviour change interventions may result from failure to consider a distinction between approaches by which behaviour increases and decreases in frequency. The distinction is not well represented in methods for designing interventions. This review aimed to identify whether there is a theoretical rationale to support this distinction.

METHODS

Using Critical Interpretative Synthesis, this conceptual review included papers from a broad range of fields (biology, psychology, education, business) likely to report approaches for increasing or decreasing behaviour. Articles were identified from databases using search terms related to theory and behaviour change. Articles reporting changes in frequency of behaviour and explicit use of theory were included. Data extracted were direction of behaviour change, how theory was operationalised, and theory-based recommendations for behaviour change. Analyses of extracted data were conducted iteratively and involved inductive coding and critical exploration of ideas and purposive sampling of additional papers to explore theoretical concepts in greater detail.

RESULTS

Critical analysis of 66 papers and their theoretical sources identified three key findings: (1) 9 of the 15 behavioural theories identified do not distinguish between implementation and de-implementation (5 theories were applied to only implementation or de-implementation, not both); (2) a common strategy for decreasing frequency was substituting one behaviour with another. No theoretical basis for this strategy was articulated, nor were methods proposed for selecting appropriate substitute behaviours; (3) Operant Learning Theory makes an explicit distinction between techniques for increasing and decreasing frequency.

DISCUSSION

Behavioural theories provide little insight into the distinction between implementation and de-implementation. Operant Learning Theory identified different strategies for implementation and de-implementation, but these strategies may not be acceptable in health systems. Additionally, if behaviour substitution is an approach for de-implementation, further investigation may inform methods or rationale for selecting the substitute behaviour.

Structural Inequities and Social Networks Impact Hormone Use and Misuse Among Transgender Women in Los Angeles County

In order to reduce gender dysphoria and combat stigma, transgender women often affirm their gender through social and medical transition, which may include cross-sex hormone therapy. This study examined associations between medically monitored hormone use and hormone misuse (non-prescribed hormone use including "fillers"), structural inequities (access to housing, health insurance, and income), and social network dynamics among 271 transgender women in Los Angeles. Hormone use status was coded trichotomously (hormone use, hormone misuse, no hormone use), and robust multinomial logistic regression as well as novel social network analysis was conducted to examine associations. Results demonstrated that younger, African-American/Black transgender women were most likely to engage in hormone misuse compared to transgender women who were older or non-African-American/Black. One-third of the sample reported sex work as a main source of income, and this group was more likely to misuse hormones than those with another primary source of income. Transgender women with access to stable housing and health insurance were most likely to engage in medically monitored hormone use. Social network analysis revealed that transgender women with a greater number of hormone-using network alters were most likely to misuse hormones, but that using the Internet to find transgender friends mitigated this association. Results demonstrate the multifaceted risk profile of transgender women who use and misuse hormones, including that social networks play an important role in hormone usage among transgender women.

Investigating Relationships Between Health-Related Problems and Online Health Information Seeking

Online health information seeking (OHIS) functions as a coping strategy to relieve health-related stress and problems. When people rate their health as poor or felt concern about their health, they frequently visit the Internet to seek health-related information in order to understand their symptoms and treatments. Regarding this role of OHIS, it is important to understand the relationships between health-related problems and OHIS. This study applies the Common-Sense Model as a theoretical lens to examine the relationship between health-related problems (ie, diagnosis of cancer, poor self-rated health, and psychological distress) and OHIS of adults in the US. Using the Health Information National Trends Survey 4 Cycle 1 (2012), a total of 2351 adult Internet users was included in this research. Hierarchical logistic regression analyses were conducted to examine the research model, and the model adding psychological distress resulted in a statistically significant improvement in model fit. In this study, lower levels of self-rated health and higher levels of psychological distress were significantly associated with higher odds of OHIS. Study findings support the idea that individuals' low levels of self-rated health and high levels of perceived psychological distress make people search for health-related information via the Internet in order to cope with health-related concern and distress.

Does the Theory of Planned Behaviour Explain Condom Use Behaviour Among Men Who have Sex with Men? A Meta-analytic Review of the Literature

The aim of this meta-analysis was to explore whether the constructs in the theory of planned behaviour (TPB; i.e., attitude, subjective norm, perceived behavioural control, intention) explain condom use behaviour among men who have sex with men (MSM). Electronic databases were searched for studies that measured TPB variables and MSM condom use. Correlations were meta-analysed using a random effects model and path analyses. Moderation analyses were conducted for the time frame of the behavioural measure used (retrospective versus prospective). Attitude, subjective norm and perceived behavioural control accounted for 24.0 % of the variance in condom use intention and were all significant correlates. Intention and PBC accounted for 12.4 % of the variance in condom use behaviour. However, after taking intention into account, PBC was no longer significantly associated with condom use. The strength of construct relationships did not differ between retrospective and prospective behavioural assessments. The medium to large effect sizes of the relationships between the constructs in the TPB, which are consistent with previous meta-analyses with different behaviours or target groups, suggest that the TPB is also a useful model for explaining condom use behaviour among MSM. However, the research in this area is rather small, and greater clarity over moderating factors can only be achieved when the literature expands.

Modeling Online Health Information-Seeking Behavior in China: The Roles of Source Characteristics, Reward Assessment, and Internet Self-Efficacy

The outbreak of severe acute respiratory syndrome (SARS) in 2003 marked the explosion of health information seeking online in China and the increasing emergence of Chinese health websites. There are both benefits and potential hazards of people's online health information seeking. This article intended to test part of Wilson's second model of information behavior, including source characteristics and activating mechanisms, and to identify the relationships among perceived access, perceived expertise credibility, reward assessment, Internet self-efficacy, and online health information-seeking behavior. Data were drawn from face-to-face surveys and an online survey of health information seekers (N = 393) in China. The results showed that source characteristics predicted activating mechanisms, which in turn predicted online health information-seeking behavior. Activating mechanisms, that is, reward assessment and Internet self-efficacy, mediated the relationship between source characteristics (i.e., access and credibility) and online health information-seeking behavior. Strategies for improving information access, expertise credibility, and Internet self-efficacy are discussed in order to maximize the benefits of online health information seeking and to minimize the potential harm.

Health-Related Everyday Functioning in the Internet Age: HIV-Associated Neurocognitive Disorders Disrupt Online Pharmacy and Health Chart Navigation Skills

This study evaluated the effects of HIV-associated Neurocognitive Disorders (HAND) on 2 Internet-based tests of healthcare management. Study participants included 46 individuals with HIV infection, 19 of whom were diagnosed with HAND, and 21 seronegatives. Participants were administered Internet-based tests of online pharmacy and health records navigation skills in which they used mock credentials to log in to an experimenter-controlled website and independently perform a series of typical online health-related behaviors (e.g., refill a prescription, read and interpret an electronic chart note). HAND was associated with significantly lower accuracy on both the online pharmacy and health records navigation tasks. Among the HIV+ participants, poorer performance on the online healthcare navigation tasks was associated with fewer years of education, higher plasma viral load, less frequent Internet use, and lower health literacy. Findings indicate that individuals with HAND may have marked difficulties navigating the Internet to complete important health-related behaviors.

The Association Between Online Health Information-Seeking Behaviors and Health Behaviors Among Hispanics in New York City: A Community-Based Cross-Sectional Study

Background

Hispanics are the fastest-growing minority group in the United States and they suffer from a disproportionate burden of chronic diseases. Studies have shown that online health information has the potential to affect health behaviors and influence management of chronic disease for a significant proportion of the population, but little research has focused on Hispanics.

Objective

The specific aim of this descriptive, cross-sectional study was to examine the association between online health information–seeking behaviors and health behaviors (physical activity, fruit and vegetable consumption, alcohol use, and hypertension medication adherence) among Hispanics.

Methods

Data were collected from a convenience sample (N=2680) of Hispanics living in northern Manhattan by bilingual community health workers in a face-to-face interview and analyzed using linear and ordinal logistic regression. Variable selection and statistical analyses were guided by the Integrative Model of eHealth Use.

Results

Only 7.38% (198/2680) of the sample reported online health information–seeking behaviors. Levels of moderate physical activity and fruit, vegetable, and alcohol consumption were low. Among individuals taking hypertension medication (n=825), adherence was reported as high by approximately one-third (30.9%, 255/825) of the sample. Controlling for demographic, situational, and literacy variables, online health information–seeking behaviors were significantly associated with fruit (β=0.35, 95% CI 0.08-0.62, P=.01) and vegetable (β=0.36, 95% CI 0.06-0.65, P=.02) consumption and physical activity (β=3.73, 95% CI 1.99-5.46, P<.001), but not alcohol consumption or hypertension medication adherence. In the regression models, literacy factors, which were used as control variables, were associated with 3 health behaviors: social networking site membership (used to measure one dimension of computer literacy) was associated with fruit consumption (β=0.23, 95% CI 0.05-0.42, P=.02), health literacy was associated with alcohol consumption (β=0.44, 95% CI 0.24-0.63, P<.001), and hypertension medication adherence (β=–0.32, 95% CI –0.62 to –0.03, P=.03). Models explained only a small amount of the variance in health behaviors.

Conclusions

Given the promising, although modest, associations between online health information–seeking behaviors and some health behaviors, efforts are needed to improve Hispanics’ ability to access and understand health information and to enhance the availability of online health information that is suitable in terms of language, readability level, and cultural relevance.

General and health-related Internet use among an urban, community-based sample of HIV-positive women: implications for intervention development

Internet-based HIV interventions are increasingly common, although little focus has been on HIV-positive women. To understand the feasibility of using the Internet to deliver behavioral interventions to HIV-positive women, we sought to describe patterns of Internet use for general and health-related purposes and to explore differences between Internet-using and non-using women. From February 2014 to April 2014, 103 women were recruited at six community-based organizations in the Bronx, NY that provide services to HIV-positive persons. Women completed a 30-minute interview and answered a brief survey of socio-demographic factors, risk behavior and clinical characteristics. We performed χ(2) and Kruskal-Wallis tests to compare Internet users and non-users. Sixty-one percent of participants were current Internet users, most of whom used a personal electronic device (e.g., cellphone/smartphone) to access the Internet. While higher proportions of Internet users were passively engaged (e.g., signed up to receive email updates [42.9%] or watched an online video [58.7%] for health-related purposes), smaller proportions (12.7-15.9%) were involved in more interactive activities such as posting comments, questions, or information about health-related issues in an online discussion or a blog. A majority of Internet non-users (60.0%) expressed interest in going online. Lack of computer or Internet access (37.5%) and Internet navigation skills (37.5%) were the primary reasons for non-use. Compared with non-users, Internet users were more likely to be younger, to have higher socioeconomic status, and to report low health-related social support. Despite having a lower proportion of Internet users in our study than the general population, Internet-using women in our study had relatively high levels of online engagement and went online for both general and health-related purposes. However, Internet-based interventions targeting HIV-positive women will likely need to include providing computer and/or Internet access as well as training participants in how to navigate the Internet.

HIV-infected Women's Perspectives on the Use of the Internet for Social Support: A Potential Role for Online Group-based Interventions

While the development and implementation of HIV-related online interventions has expanded, few have been tailored for women or have leveraged Web 2.0's capabilities to provide social support. We conducted semi-structured interviews with 27 women with HIV at an urban community health center to understand their perspectives on the potential role of the Internet and the use of an online group format to provide social support. Data were analyzed using the constant comparative method. We identified six themes: a need for groups and increased sense of connectedness, convenience and accessibility, trust as a precondition for participating, online groups as a potential facilitator or barrier to expression, limited digital access and literacy, and privacy concerns. Overall, women were highly supportive of online group-based interventions but acknowledged the need for increased digital access and Internet navigation training. Hybrid (in-person and online) interventions may be most useful for women with HIV.

Online health information seeking behaviors of Hispanics in New York City: a community-based cross-sectional study

BACKGROUND

The emergence of the Internet has increased access to health information and can facilitate active individual engagement in health care decision making. Hispanics are the fastest-growing minority group in the United States and are also the most underserved in terms of access to online health information. A growing body of literature has examined correlates of online health information seeking behaviors (HISBs), but few studies have included Hispanics.

OBJECTIVE

The specific aim of this descriptive, correlational study was to examine factors associated with HISBs of Hispanics.

METHODS

The study sample (N=4070) was recruited from five postal zip codes in northern Manhattan for the Washington Heights Inwood Informatics Infrastructure for Comparative Effectiveness Research project. Survey data were collected via interview by bilingual community health workers in a community center, households, and other community settings. Data were analyzed using bivariate analyses and logistic regression.

RESULTS

Among individual respondents, online HISBs were significantly associated with higher education (OR 3.03, 95% CI 2.15-4.29, P<.001), worse health status (OR 0.42, 95% CI 0.31-0.57, P<.001), and having no hypertension (OR 0.60, 95% CI 0.43-0.84, P=.003). Online HISBs of other household members were significantly associated with respondent factors: female gender (OR 1.60, 95% CI 1.22-2.10, P=.001), being younger (OR 0.75, 95% CI 0.62-0.90, P=.002), being married (OR 1.36, 95% CI 1.09-1.71, P=.007), having higher education (OR 1.80, 95% CI 1.404-2.316, P<.001), being in worse health (OR 0.59, 95% CI 0.46-0.77, P<.001), and having serious health problems increased the odds of their household members' online HISBs (OR 1.83, 95% CI 1.29-2.60, P=.001).

CONCLUSIONS

This large-scale community survey identified factors associated with online HISBs among Hispanics that merit closer examination. To enhance online HISBs among Hispanics, health care providers and policy makers need to understand the cultural context of the Hispanic population. Results of this study can provide a foundation for the development of informatics-based interventions to improve the health of Hispanics in the United States.

Interventions to assist health consumers to find reliable online health information: a comprehensive review

Background

Health information on the Internet is ubiquitous, and its use by health consumers prevalent. Finding and understanding relevant online health information, and determining content reliability, pose real challenges for many health consumers.

Purpose

To identify the types of interventions that have been implemented to assist health consumers to find reliable online health information, and where possible, describe and compare the types of outcomes studied.

Data Sources

PubMed, PsycINFO, CINAHL Plus and Cochrane Library databases; WorldCat and Scirus ‘gray literature’ search engines; and manual review of reference lists of selected publications.

Study Selection

Publications were selected by firstly screening title, abstract, and then full text.

Data Extraction

Seven publications met the inclusion criteria, and were summarized in a data extraction form. The form incorporated the PICOS (Population Intervention Comparators Outcomes and Study Design) Model. Two eligible gray literature papers were also reported.

Data Synthesis

Relevant data from included studies were tabulated to enable descriptive comparison. A brief critique of each study was included in the tables. This review was unable to follow systematic review methods due to the paucity of research and humanistic interventions reported.

Limitations

While extensive, the gray literature search may have had limited reach in some countries. The paucity of research on this topic limits conclusions that may be drawn.

Conclusions

The few eligible studies predominantly adopted a didactic approach to assisting health consumers, whereby consumers were either taught how to find credible websites, or how to use the Internet. Common types of outcomes studied include knowledge and skills pertaining to Internet use and searching for reliable health information. These outcomes were predominantly self-assessed by participants. There is potential for further research to explore other avenues for assisting health consumers to find reliable online health information, and to assess outcomes via objective measures.

How many bytes does it take? A content analysis of cyber issues in couple and family therapy journals

In the fifteen years since the explosion of the Internet, using cyber technology for work and social functions has exponentially increased. Yet, questions around how to manage such changes remain elusive in family therapy literature. In this investigation, we conducted a content analysis to determine to what extent marriage/couple and family therapy (M/CFT) journals have responded to the integration of the Internet in couple and family life. We found 79 of 13,274 articles across seventeen journals focused on the Internet in some capacity. Implications for clinical practice, training, and future research are discussed.

The Psychology of AIDS Denialism

More than 34 million people in the world are living with HIV/AIDS. Each year there are nearly three million new HIV infections and nearly two million AIDS-related deaths. In the face of these staggering statistics, there is a vocal group of individuals who deny reality and claim that HIV is harmless or may not even exist at all. Mirroring the AIDS pandemic itself, AIDS denialism is a threat to public health. AIDS denialism propagates the views of a few rogue scientists through press releases, social media, and a significant presence on the Internet. AIDS Denialists aim to undermine HIV testing, prevention, and treatment. Most tragic has been the adoption of AIDS Denialist views by public officials, perhaps none more infamous than former President of South Africa Thabo Mbeki. This article examines the psychology of AIDS denialism, focusing on its emergence from the earliest days of AIDS and its grounding in conspiracy thinking and medical mistrust. The article also describes the tactics and rhetoric of AIDS denialism and those who are most vulnerable to AIDS Denialist claims. Recommendations are offered for countering AIDS denialism by exposing its fake experts and baseless claims.

A web-based intervention trial for depressive symptoms and subjective well-being in patients with chronic HIV infection

The current study examined the efficacy of a web-based intervention (WBI; Avanti) on symptoms of depression and well-being for patients diagnosed with HIV. A two-armed randomized trial recruited patients on antiretroviral therapy (ART) at an outpatient clinic. Thirty-six patients were allocated to Avanti and 31 patients to a control group. Primary outcomes were symptoms of depression and subjective well-being (SWB), and secondary outcomes included life satisfaction and affect balance. Paired tests showed that only patients following Avanti had significant improvements in SWB by 3 months as well as affect balance. No significant differences between groups were detected in any of the outcome parameters at baseline after 3 months, as expected from group size and variability in the parameters. However, time since HIV diagnosis and ART initiation moderated the effects of Avanti. In conclusion, our data show that patients with HIV infection may benefit from a WBI in adjunct to medical treatment.

Creating comprehensive, youth centered, culturally appropriate sex education: What do young gay, bisexual and questioning men want?

We examined young gay, bisexual and questioning men's (YGBQM) experiences with school-based sex education as they sought to learn about sex and sexual health, and their suggestions for improving same-sex education resources. Thematic analysis of 30 in-depth interviews with YGBQM (ages 18-24) underscored the discrepancies between the existing school-based sex education curricula and YGBQM's perceived sex education needs. Our results show that many youths' sexuality and same-sex sexual behaviors are excluded in sex education lessons; however, YGBQM noted that they sought out other resources (e.g., websites) to answer their questions. We discuss YGBQM's ideas for the creation of a sex and sexual health website that would be tailored for youth like themselves, including topics and features that an ideal website would contain. In addition, we present recommended changes to existing school-based sexual education curricula.

Opportunities for engaging low-income, vulnerable populations in health care: a systematic review of homeless persons' access to and use of information technologies

We systematically reviewed the health and social science literature on access to and use of information technologies by homeless persons by searching 5 bibliographic databases. Articles were included if they were in English, represented original research, appeared in peer-reviewed publications, and addressed our research questions. Sixteen articles met our inclusion criteria. We found that mobile phone ownership ranged from 44% to 62%; computer ownership, from 24% to 40%; computer access and use, from 47% to 55%; and Internet use, from 19% to 84%. Homeless persons used technologies for a range of purposes, some of which were health related. Many homeless persons had access to information technologies, suggesting possible health benefits to developing programs that link homeless persons to health care through mobile phones and the Internet.

Development and evaluation of an internet and personal health record training program for low-income patients with HIV or hepatitis C

BACKGROUND

Vulnerable populations face difficulties accessing and using the internet and personal health record (PHR) systems for health-related purposes. Populations disconnected from the internet also tend to be disconnected from health care services.

OBJECTIVES

To develop and evaluate an intervention to increase skills in health-related internet and PHR use for vulnerable populations with limited computer and internet experience.

RESEARCH DESIGN

Preevaluation and postevaluation using quantitative surveys, semistructured interviews, focus groups, and ethnographic observation.

SUBJECTS

Fourteen low-income Veterans receiving care at Veterans Affairs medical centers for human immunodeficiency virus or hepatitis C.

MEASURES

Internet and PHR use, self-efficacy, patient activation, disease knowledge, predictors of medication adherence.

RESULTS

At follow-up one (FU1), mean number of internet for health features used increased from 1.57 to 4.07 (P<0.001) as did number of PHR features, from 0.36 to 2.00 (P<0.001). Mean self-efficacy increased at FU1, from 7.12 to 8.60, (P=0.009) and was maintained at follow-up two (FU2). Patient activation increased only at FU2, from 3.42 to 3.61 (P=0.03). Disease specific knowledge showed borderline increase at FU1, from 67.9% to 72.2% (P=0.05), whereas there were no changes in predictors of medication adherence. Qualitative findings underscored the interest in using internet and PHRs and their contribution to increased engagement in care. Training cost per participant was $287.

CONCLUSIONS

Group training of vulnerable patients represents a cost-effective method to increase internet and PHR skills, and improve patient confidence in finding health-related information, making online health-related transactions, and interacting with health care providers.

Online health-searching behavior among HIV-seropositive and HIV-seronegative men who have sex with men in the Baltimore and Washington, DC area

Background

Searching online for health information is common among American adults. However, there have been few studies to investigate the online health-searching behaviors among men who have sex with men (MSM) with human immunodeficiency virus (HIV).

Objective

To estimate the prevalence of Internet use among HIV-seropositive MSM and compare their online behaviors with HIV-seronegative men with chronic disease(s).

Methods

This study was performed at the Baltimore/Washington, DC site of the Multicenter AIDS Cohort Study (MACS). A total of 200 MACS participants were asked to answer a self-administered questionnaire on a first-come basis during a semiannual study visit (from July to November 2011); 195 (97.5%) participants completed the survey. Multiple logistic regression models were used to investigate the factors influencing their online health-searching behaviors.

Results

The median age of the 195 MSM participants was 57 years, 64.6% were white, 59.0% were employed, and 88.2% had Internet access at home and/or other locations. Of the 95 HIV-seropositive participants, 89.5% currently used highly active antiretroviral therapy (HAART) and 82.1% had Internet access. After adjusting for age and race/ethnicity, the HIV-seropositive participants were less likely to perform online searches for general disease-related information compared to the HIV-seronegative men with chronic disease(s) (OR 0.20, 95% CI 0.06-0.68, P=.01). There were no statistically significant associations with HIV status and searching for new medications/treatments (OR 0.55, 95% CI 0.19-1.55, P=.26) or support/advice from other patients (OR 0.52, 95% CI 0.18-1.53, P=.24). Increasing age by 5 years led to a decrease by 29% in the odds of online health-related searches for general information (OR 0.71, 95% CI 0.52-0.98, P=.03) and 26% for support/advice from other patients (OR 0.74, 95% CI 0.56-0.98, P=.03). A decrease of 25% for new medications/treatments was also seen, but was not statistically significant (OR 0.75, 95% CI 0.57-1.01, P=.06).

Conclusions

This study shows that HIV-seropositive MSM have similar online health-searching behaviors as HIV-seronegative men with chronic disease(s). Independent of HIV status, older MSM are less likely to perform online health-related searches.

Targeting HIV prevention messaging to a new generation of gay, bisexual, and other young men who have sex with men

HIV prevention messaging has been shown to reduce or delay high-risk sexual behaviors in young men who have sex with men (YMSM). Since the onset of the HIV/AIDS epidemic, a new generation of YMSM has come of age during an evolution in communication modalities. Because both these communication technologies and this new generation remain understudied, the authors investigated the manner in which YMSM interact with HIV prevention messaging. In particular, the authors examined 6 venues in which YMSM are exposed to, pay attention to, and access HIV prevention information: the Internet, bars/dance clubs, print media, clinics/doctors' offices, community centers/agencies, and educational classes. Data were drawn from a community-based sample of 481 racially and ethnically diverse YMSM from New York City. Significant differences in exposure to HIV prevention messaging venues emerged with respect to age, race/ethnicity, and sexual orientation. Attention paid to HIV prevention messages in various venues differed by age and sexual orientation. Across all venues, multivariate modeling indicated YMSM were more likely to access HIV messaging from the same venues at which they paid attention, with some variability explained by person characteristics (age and perceived family socioeconomic status). This suggests that the one-size-fits-all approach does not hold true, and both the venue and person characteristics must be considered when generating and disseminating HIV prevention messaging.

Bridging the digital divide in HIV care: a pilot study of an iPod personal health record

BACKGROUND

Persons living with HIV (PLWH) need practical tools to self-manage their condition.

METHODS

We conducted a proof-of-concept study among PLWH to assess whether patients could learn to use a personal health record (PHR) on a hand-held device (iPod Touch) to manage their condition. We began individual trainings and later adapted this to group training. We assessed usability, acceptability and also effects on self-efficacy for treatment adherence using the HIV Treatment Adherence Self-Efficacy Scale (HIV-ASES).

RESULTS

Nine PLWH participated in the individual training and 29 participated in the group sessions. The participants were largely middle aged, low-income and of racial/ethnic minorities. The sessions were well attended and participants fully engaged in tasks and shared learning. Most participants stated they intended to use the PHR and reported improved self-efficacy in treatment adherence (P = .05) particularly on the integration of treatment adherence into one's routine (P < .02).

CONCLUSIONS

Training PLWH in use of a handheld PHR shows promise.

Mobilizing homeless youth for HIV prevention: a social network analysis of the acceptability of a face-to-face and online social networking intervention

The objective of the study is to use social network analysis to examine the acceptability of a youth-led, hybrid face-to-face and online social networking HIV prevention program for homeless youth.Seven peer leaders (PLs) engaged face-to-face homeless youth (F2F) in the creation of digital media projects (e.g. You Tube videos). PL and F2F recruited online youth (OY) to participate in MySpace and Facebook communities where digital media was disseminated and discussed. The resulting social networks were assessed with respect to size, growth, density, relative centrality of positions and homophily of ties. Seven PL, 53 F2F and 103 OY created two large networks. After the first 50 F2F youth participated, online networks entered a rapid growth phase. OY were among the most central youth in these networks. Younger aged persons and females were disproportionately connected to like youth. The program appears highly acceptable to homeless youth. Social network analysis revealed which PL were the most critical to the program and which types of participants (younger youth and females) may require additional outreach efforts in the future.

Use of dietary supplements among people living with HIV/AIDS is associated with vulnerability to medical misinformation on the internet

Background

Use of dietary supplements is common among people living with HIV/AIDS. Because dietary supplements are used in the context of other health behaviors, they may have direct and indirect health benefits. However, supplements may also be associated with vulnerability to medical misinformation and unfounded health claims. We examined use of dietary supplements among people living with HIV/AIDS (PLWH) and the association between use of dietary supplements and believing medical misinformation.

Methods

A convenience sample of 268 men and 76 women living with HIV was recruited from AIDS services and clinics in Atlanta, GA. Participants completed measures of demographic and health characteristics, dietary supplement use, beliefs about dietary supplements, internet use, and an internet evaluation task designed to assess vulnerability to medical misinformation.

Results

One out of four PLWH currently used at least one dietary supplement product excluding vitamins. Dietary supplement use was associated with higher education and greater use of the internet for health-related information. Dietary supplement users also endorsed greater believability and trust in unfounded claims for HIV cures.

Conclusions

Dietary supplement use is common among PLWH and is associated with a broad array of health information seeking behaviors. Interventions are needed to reduce the vulnerability of PLWH, particularly dietary supplement users, to medical misinformation propagated on the internet.

Exploring digital divides: An examination of eHealth technology use in health information seeking, communication and personal health information management in the USA

Recent government initiatives to deploy health information technology in the USA, coupled with a growing body of scholarly evidence linking online heath information and positive health-related behaviors, indicate a widespread belief that access to health information and health information technologies can help reduce healthcare inequalities. However, it is less clear whether the benefits of greater access to online health information and health information technologies is equitably distributed across population groups, particularly to those who are underserved. To examine this issue, this article employs the 2007 Health Information National Trends Survey (HINTS) to investigate relationships between a variety of socio-economic variables and the use of the web-based technologies for health information seeking, personal health information management and patient-provider communication within the context of the USA. This study reveals interesting patterns in technology adoption, some of which are in line with previous studies, while others are less clear. Whether these patterns indicate early evidence of a narrowing divide in eHealth technology use across population groups as a result of the narrowing divide in Internet access and computer ownership warrants further exploration. In particular, the findings emphasize the need to explore differences in the use of eHealth tools by medically underserved and disadvantaged groups. In so doing, it will be important to explore other psychosocial variables, such as health literacy, that may be better predictors of health consumers’ eHealth technology adoption.

HIV and depression--a systematic review of interventions

HIV-positive individuals are more likely to be diagnosed with major depressive disorder than HIV-negative individuals. Depression can precede diagnosis and be associated with risk factors for infection. The experience of illness can also exacerbate depressive episodes and depression can be a side effect to treatment. A systematic understanding of which interventions have been tested in and are effective with HIV-seropositive individuals is needed. This review aims to provide a comprehensive understanding of evaluated interventions related to HIV and depression and provide some insight on questions of prevalence and measurement. Standard systematic research methods were used to gather quality published papers on HIV and depression. From the search, 1015 articles were generated and hand searched resulting in 90 studies meeting adequacy inclusion criteria for analysis. Of these, 67 (74.4%) were implemented in North America (the US and Canada) and 14 (15.5%) in Europe, with little representation from Africa, Asia and South America. Sixty-five (65.5%) studies recruited only men or mostly men, of which 31 (35%) recruited gay or bisexual men. Prevalence rates of depression ranged from 0 to 80%; measures were diverse and rarely adopted the same cut-off points. Twenty-one standardized instruments were used to measure depression. Ninety-nine interventions were investigated. The interventions were diverse and could broadly be categorized into psychological, psychotropic, psychosocial, physical, HIV-specific health psychology interventions and HIV treatment-related interventions. Psychological interventions were particularly effective and in particular interventions that incorporated a cognitive-behavioural component. Psychotropic and HIV-specific health psychology interventions were generally effective. Evidence is not clear-cut regarding the effectiveness of physical therapies and psychosocial interventions were generally ineffective. Interventions that investigated the effects of treatments for HIV and HIV-associated conditions on depression generally found that these treatments did not increase but often decreased depression. Interventions are both effective and available, although further research into enhancing efficacy would be valuable. Depression needs to be routinely logged in those with HIV infection during the course of their disease. Specific data on women, young people, heterosexual men, drug users and those indiverse geographic areas are needed. Measurement of depression needs to be harmonized and management into care protocols incorporated.

Internet health information seeking behavior and antiretroviral adherence in persons living with HIV/AIDS

Abstract While the Internet has the potential to educate persons living with HIV/AIDS (PLWHA), websites may contain inaccurate information and increase the risk of nonadherence with antiretroviral therapy (ART). The objectives of our study were to determine the extent to which PLWHA engage in Internet health information seeking behavior (IHISB) and to determine whether IHISB is associated with ART adherence. We conducted a survey of adult, English-speaking HIV-infected patients at four HIV outpatient clinic sites in the United States (Baltimore, Maryland; Detroit, Michigan; New York, and Portland, Oregon) between December 2004 and January 2006. We assessed IHISB by asking participants how much information they had received from the Internet since acquiring HIV. The main outcome was patient-reported ART adherence over the past three days. Data were available on IHISB for 433 patients, 334 of whom were on ART therapy. Patients had a mean age of 45 (standard error [SE] 0.45) years and were mostly male (66%), African American (58%), and had attained a high school degree (73%). Most (55%) reported no IHISB, 18% reported some, and 27% reported "a fair amount" or "a great deal." Patients who reported higher versus lower levels of IHISB were significantly younger, had achieved a higher level of education, and had higher medication self-efficacy. In unadjusted analyses, higher IHISB was associated with ART adherence (odds ratio [OR], 2.96, 95% confidence interval [CI] 1.27-6.94). This association persisted after adjustment for age, gender, race, education, clinic site, and medication self-efficacy (adjusted odds ratio [AOR] 2.76, 95% CI 1.11-6.87). Our findings indicate that IHISB is positively associated with ART adherence even after controlling for potentially confounding variables. Future studies should investigate the ways in which Internet health information may promote medication adherence among PLWHA.

Interventions for enhancing consumers' online health literacy

BACKGROUND

Access to health information is critical to enable consumers to participate in decisions on health. Increasingly, such information is accessed via the internet, but a number of barriers prevent consumers making effective use of it. These barriers include inadequate skills to search, evaluate and use the information. It has not yet been demonstrated whether training consumers to use the internet for health information can result in positive health outcomes.

OBJECTIVES

To assess the effects of interventions for enhancing consumers' online health literacy (skills to search, evaluate and use online health information).

SEARCH STRATEGY

We searched: the Cochrane Consumers and Communication Review Group Specialised Register; Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 1 2008); MEDLINE (Ovid); EMBASE (Ovid); CINAHL (Dialog); ERIC (CSA Illumina); LISA (CSA Illumina); PsycINFO (Ovid); Index to scientific and technical proceedings; SIGLE; ASLIB Index to Theses; ProQuest Dissertation Abstracts; National Research Register/UK CRN Portfolio database; Current Controlled Trials - MetaRegister of Controlled Trials. We searched all databases for the period January 1990 to March 2008.

SELECTION CRITERIA

Randomised controlled trials (RCTs), cluster RCTs and associated economic evaluations, quasi-RCTs, interrupted time series analyses, and controlled before and after (CBA) studies assessing interventions to enhance consumers' online health literacy, in any language.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies for inclusion, assessed their quality and extracted data. We contacted study authors for clarification and to seek missing data. We presented results as a narrative and tabular summary, and calculated mean differences where appropriate.

MAIN RESULTS

We included two studies: one randomised controlled trial (RCT) and one controlled before and after (CBA) study with a combined total of 470 participants. The RCT compared internet health information classes with patient education classes for participants with HIV infection. Only the RCT, which we rated as having a moderate risk of bias, reported statistically significant positive effects for primary outcomes related to online health literacy in the intervention group, for the following outcomes: 'Self-efficacy for health information seeking', 'health information evaluation skills' and the 'number of times the patient discussed online information with a health provider'. The CBA, which we rated as having a high risk of bias, compared internet health information classes with a control group receiving no intervention among healthy adults aged 50+. It showed significant positive changes only in a secondary (behavioural) outcome in the intervention group, regarding the readiness to adopt the internet as a tool for preventive health information. No adverse effects were reported.There is low quality evidence that such interventions may improve some outcomes relevant to online health literacy in certain populations.

AUTHORS' CONCLUSIONS

Due to the small number of studies and their variable methodological quality, the evidence is too weak to draw any conclusions about implications for the design and delivery of interventions for online health literacy. There is a need for well-designed RCTs to investigate the effects of such interventions. These should involve different participants (in terms of disease status, age, socio-economic group and gender) to analyse the extent to which online health literacy reduces a barrier to using the internet for health information. Trials should be conducted in different settings and should examine interventions to enhance consumers' online health literacy (search, appraisal and use of online health information) like internet training courses, measuring outcomes up to at least one year after the intervention to estimate the sustainability of the intervention effects.

"There is no proof that HIV causes AIDS": AIDS denialism beliefs among people living with HIV/AIDS

AIDS denialists offer false hope to people living with HIV/AIDS by claiming that HIV is harmless and that AIDS can be cured with natural remedies. The current study examined the prevalence of AIDS denialism beliefs and their association to health-related outcomes among people living with HIV/AIDS. Confidential surveys and unannounced pill counts were collected from a convenience sample of 266 men and 77 women living with HIV/AIDS that was predominantly middle-aged and African American. One in five participants stated that there is no proof that HIV causes AIDS and that HIV treatments do more harm than good. AIDS denialism beliefs were more often endorsed by people who more frequently used the internet after controlling for confounds. Believing that there is a debate among scientists about whether HIV causes AIDS was related to refusing HIV treatments and poorer health outcomes. AIDS denialism beliefs may be common among people living with HIV/AIDS and such beliefs are associated with poor health outcomes.

Challenges and recommendations for blinding in behavioral interventions illustrated using a case study of a behavioral intervention to lower blood pressure

OBJECTIVE

To describe the challenges to blinding in behavioral interventions, specifically those for asymptomatic medical conditions, where the intervention is through counseling, and to provide recommendations for achieving blinding in behavioral randomized controlled trials (RCTs).

METHODS

This paper reviews the challenges of preserving blinding in behavioral RCTs with a focus on interventions for asymptomatic medical conditions. This is illustrated using a case study of an ongoing behavioral intervention to improve hypertension control.

RESULTS

In contrast to easily keeping study investigators and participants masked to treatment assignment through the use of identical pills or sham treatments, the need to have differing levels of blinding among study personnel and participants in randomized behavioral intervention trials is presented. Recommendations for achieving this are provided.

CONCLUSIONS

Despite the challenges inherent in behavioral interventions, it is possible to achieve differing levels of blinding across study personnel and participants to minimize bias and generate valid data in RCTs that test interventions for asymptomatic medical conditions such as hypertension. Modifications may be needed for RCTs in symptomatic medical conditions.

PRACTICE IMPLICATIONS

Researchers designing behavioral RCTs should be aware of the challenges to blinding all staff and study participants, and plan to have procedures in place to standardize outcome data collection and intervention delivery without compromising the varying levels of blinding. The challenges and recommendations described may need modifications in behavioral intervention studies for symptomatic conditions.

A systematic review of patient acceptance of consumer health information technology

A systematic literature review was performed to identify variables promoting consumer health information technology (CHIT) acceptance among patients. The electronic bibliographic databases Web of Science, Business Source Elite, CINAHL, Communication and Mass Media Complete, MEDLINE, PsycArticles, and PsycInfo were searched. A cited reference search of articles meeting the inclusion criteria was also conducted to reduce misses. Fifty-two articles met the selection criteria. Among them, 94 different variables were tested for associations with acceptance. Most of those tested (71%) were patient factors, including sociodemographic characteristics, health- and treatment-related variables, and prior experience or exposure to computer/health technology. Only ten variables were related to human-technology interaction; 16 were organizational factors; and one was related to the environment. In total, 62 (66%) were found to predict acceptance in at least one study. Existing literature focused largely on patient-related factors. No studies examined the impact of social and task factors on acceptance, and few tested the effects of organizational or environmental factors on acceptance. Future research guided by technology acceptance theories should fill those gaps to improve our understanding of patient CHIT acceptance, which in turn could lead to better CHIT design and implementation.

A tailored Internet-plus-email intervention for increasing physical activity among ethnically-diverse women

OBJECTIVE

To evaluate the feasibility and efficacy of an individually tailored, Internet-plus-email physical activity intervention designed for adult women.

METHOD

Healthy and ethnically-diverse adult females (N=156) (mean age=42.8 years, 65% Caucasian) from California were randomly assigned to an intervention (access to a tailored website and weekly emails) or wait-list control group. Participants completed web-based assessments of physical activity, stage of behavior change, and psychosocial variables at baseline, one month, two months, and three months. Data were collected during 2006-2007. Multilevel random coefficient modeling examined group differences in rates of change.

RESULTS

As compared to the control condition, the intervention group increased walking (+69 versus +32 min per week) and total moderate-to-vigorous physical activity (+23 versus -25 min per week) after three months. The intervention did not impact stage of behavior change or any of the other psychosocial variables.

CONCLUSION

A tailored, Internet-based intervention for adult women had a positive effect on walking and moderate-to-vigorous physical activity in an ethnically-diverse sample. However, given the lack of comparable research contact in the control group, these findings should be taken cautiously.
