Information e-services are useful for exchanging information among many users, whether human or automated agent; however, e-service users are susceptible to risk of inaccurate information, since users have no traditional face-to-face interaction or past relational history with information providers. To encourage use of information e-services, individuals must have technology to assess information accuracy and information source trustworthiness. This research permits automated e-service users—here called agents—acting on behalf of humans, to employ policies, or heuristics, for predicting information accuracy when numerous pieces of information are received from multiple sources. These intuitive policies draw from human strategies for evaluating the trustworthiness of information to not only identify accurate information, but also distinguish untrustworthy information providers. These policies allow the agent to build a user’s confidence in the trust assessment technology by creating justifications for trust assessment decisions and identifying particular policies integral to a given assessment decision.

During a global health crisis, people are exposed to vast amounts of information from a variety of sources. Here, we assessed which information sources could increase COVID- 19 knowledge by endorsing accurate information and refuting inaccurate information. A nationally representative sample of 1060 Cloud Research participants first rated the accuracy of a set of statements about COVID-19 (belief pre-test). Then, they were randomly assigned to one of 10 between-subjects conditions for which we varied the source that provided belief-relevant information: a political leader (President Trump or Vice-President Biden), a health authority (Doctor Fauci or the CDC), an anecdote (of a Democrat or a Republican), a large group of prior participants (Democrats, Republicans, or No affiliation), or no source (Control Condition). Finally, they rated the accuracy of the initial set of statements again (belief post-test). We found that, compared to the Control Condition, participants increased in COVID-19 knowledge by changing their beliefs to align with health authorities and with all three large groups of prior participants, and were not influenced by political leaders or anecdotes. Information source did not interact with participants’ political affiliation, suggesting that Democrats and Republicans are similarly affected by COVID-19 information sources.

BACKGROUND Very few evidence-based eHealth interventions for caregivers of people with dementia are implemented into practice. Municipalities are one promising context to implement these interventions, due to their available policy and innovation incentives regarding (dementia) caregiving and prevention. In this study, two evidence-based eHealth interventions for caregivers of people with dementia (Partner in Balance and Myinlife) were implemented in eight municipalities in the Euregion Meuse-Rhine. OBJECTIVE This study’s objectives were to (1.) evaluate this implementation and (2.) investigate determinants of successful implementation. METHODS This study collected eHealth usage data, Partner in Balance coach evaluation questionnaires, and information on implementation determinants. This was done by conducting interviews with the municipality officials, based on the Measurement Instrument for Determinants of Implementation (MIDI). This data from multiple sources and perspectives was integrated and analysed to form a total picture of the municipality implementation process. RESULTS The municipality implementation of Partner in Balance and Myinlife showed varying levels of success. In the end, three municipalities planned to continue the implementation of Partner in Balance, while none planned to continue the implementation of Myinlife. The two Partner in Balance municipalities that did not consider the implementation to be successful, viewed the implementation as an external project. For Myinlife, it was clear that more face-to-face contact was needed to engage the implementing municipality and the target groups. Successful implementations were linked to implementer self-efficacy CONCLUSIONS The experiences of implementing these interventions suggested that this implementation context was feasible regarding the required budget and infrastructure. The need to foster sense of ownership and self-efficacy in implementers will be integrated into future implementation protocols, as part of standard implementation materials for municipalities and organisations implementing Myinlife and Partner in Balance.

BACKGROUND Peer support groups for people with long-term mental health problems are at the heart of recovery-oriented approaches in mental health care. When conducted face-to-face (offline) or on the Internet (online), peer support groups have proven to have differing strengths and weaknesses. Little is known about the benefits and challenges of combining the two formats. OBJECTIVE The aim of this study was to gain insights into the benefits and challenges of combining online and offline peer support groups facilitated through an Internet intervention designed to support recovery processes. METHODS In this exploratory and descriptive study, an e-recovery portal called ReConnect was used by service users in two mental health communities in Norway for 6-12 months. The portal included an online peer support forum which also facilitated participation in local in-person ReConnect-cafés. Both formats of peer support were facilitated by an employed service user consultant with lived experience of mental health problems and with training in peer support. Qualitative data about service users’ experiences of using the portal were collected through focus groups and individual interviews and inductively analyzed thematically with focus on benefits and challenges of peer support online and offline. RESULTS A total of 14 service users 22-63 years of age with various diagnoses, receiving services at both primary and specialist levels of mental health care participated in three focus groups and 10 individual interviews. Two main themes were identified in the analysis: 1) balancing anonymity and openness, and 2) enabling connectedness. These themes are further illustrated with the subthemes: i) dilemmas of anonymity and confidentiality, ii) towards self-disclosure and openness, iii) new friendships, and iv) networks in the local community. Three of the subthemes mainly describe benefits. Challenges were more implicit and cut across the subthemes. Identified challenges were linked to transitions from anonymity to revealing one’s identity, how to protect confidentiality, or to participation at face-to-face meetings in the local community. CONCLUSIONS Our study suggests that online peer support groups and offline meetings complement each other, and the combination is mainly beneficial to users. The identified benefits appeared to arise from participants’ options of one format or the other, or that they could combine formats in ways that suited their individual values and comfort zones. We also identified challenges related to combination of formats, and both formats require appropriate facilitation of peer support. Combining online formats that enable anonymity, a non-judgmental atmosphere, and 24/7 accessibility regardless of location, with offline formats that foster local, in-person community ties, is a promising concept for facilitating recovery-oriented care, and warrants continued research.

AimsTransition from CAMHS to AMH is recognised as a potential struggle for young people who suffer with poor mental health. In response to the 2017-19 NHS CQUIN project, LPT organised a monthly working group to establish the best transition process & deliver the CQUIN project.BackgroundIt is estimated that more than 25,000 young people transition each year. It is reported that this process is often handled poorly, which can result in repeat assessments and emergency admissions for this large cohort of service users at a critical stage in life. The result is that young may go on to develop more severe problems in the absence of an appropriate transition service.MethodCohort of service users eligible for transition (17yrs 6months) was identified. They were referred from CAMHS to AMH with a transition plan and referral letter. A face-to-face transition meeting was arranged which included the patient, carer & clinicians from sending & receiving services. A clinical audit was completed to ensure that care was transferred to AMH post-18th birthday of the patient. The process was followed up by pre- and post-transitions surveys.ResultFrom 110 identified service users 46% had joint-agency transition meeting and 79% had transition plan in place. 72% felt prepared to transition to AMH and 89% felt their transition goals were met. Positive comments have been received from service users.ConclusionLink workers were identified to facilitate the transition process. Flow chart was established and disseminated across LPT. Services that need an improvement will be targeted and monitored. LPT will host an event for patients and carers to involve them in enhancing the transition process.

Summary In order to understand how mutual understanding was achieved in discursive interactions between the welfare service users and service practitioners, conversation analysis was conducted in four discussion panels set up for building consensus on the appropriate structure for user participation in service management. Conversations in eight panel discussion meetings were audio-taped for analysing the talks-in-interaction therein. Drawing on the conversation analysis, the article uncovers the dynamics of consensus building among participants from different epistemic communities. Findings The study identifies the extent of divergence in views among stakeholders, which could have been obscured by the pressure to acquiesce in platform of face-to-face coordination. In the contest for truth between the welfare service users and service practitioners, personal experience has not been accepted as legitimate resource for supporting truth claims. Having limited argument resources on issues of service management, the welfare service users perceived argumentation in panel discussion a threatening venture that they chose to avoid. Avoidance was also a strategy that panel participants employed to maintain mundane interactions in the face of looming dissents. The article argues that the Habermasian communicative ethics are not panacea to the problem of coordination between the welfare service users and service practitioners. An agonistic model of democracy is called for to shift the objective of communication from gauging consensus to encouraging articulation of disagreements in the intricate user participation project. Application The article provides a new direction for developing the user participation imperative to address necessary pluralities among stakeholders of welfare services.

Background: Dissemination of the Physical Activity Guidelines for Americans (Guidelines) is needed, but how individuals respond to the Guidelines is not well understood. This surveillance study describes US adults’ reported responses to and information sources for hearing about the Guidelines and explores relationships between how respondents heard about the Guidelines and their reported response(s). Methods: Data were analyzed from the population-based 2019 Health Information National Trends Survey 5 Cycle 3. Population-weighted proportions of response were calculated. Among those who had heard about the Guidelines, binary logistic regressions examined associations between the reported response(s) and the information source and number of sources reported. Results: The analytical sample included 5047 adults. Nearly 65% of US adults reported hearing about the Guidelines, and 29% reported a behavioral response (eg, increased physical activity). Hearing about the Guidelines through health professionals (adjusted odds ratio = 2.30, 95% confidence interval, 1.45–3.65) or social media (adjusted odds ratio = 1.89, 95% confidence interval, 1.20–2.96) (vs other sources) was associated with reporting increasing physical activity. Hearing from multiple sources (vs one source) was associated with reporting increasing physical activity (adjusted odds ratio = 1.97, 95% confidence interval, 1.18–3.31). Conclusion: Findings suggest dissemination of the Guidelines across multiple channels may promote greater changes in physical activity.

Medical information is readily online to patients, family’s doctors and others in search of enhanced or supplementary information arising from healthcare concerns. To a large extent, this information varies greatly in terms of information quality and depending on the healthcare information source, is often incomplete. This study used an indirect qualitative analysis of the information completeness of 31 Indoor Air Quality (IAQ) checklists using CATPAC and found that these sources differed in both the depth and breathe of information provided. We suggest that users of healthcare information may be underserved and that healthcare information providers might act in a more collaborative way to better balance the presentation of their information in terms of depth and breathe of presented content.

Learning from multiple sources of information is an important problem in machine-learning research. The key challenges are learning representations and formulating inference methods that take into account the complementarity and redundancy of various information sources. In this paper we formulate a variational autoencoder based multi-source learning framework in which each encoder is conditioned on a different information source. This allows us to relate the sources via the shared latent variables by computing divergence measures between individual source’s posterior approximations. We explore a variety of options to learn these encoders and to integrate the beliefs they compute into a consistent posterior approximation. We visualise learned beliefs on a toy dataset and evaluate our methods for learning shared representations and structured output prediction, showing trade-offs of learning separate encoders for each information source. Furthermore, we demonstrate how conflict detection and redundancy can increase robustness of inference in a multi-source setting.

Informal trade has grown at an alarming rate in South Africa because of lack of employment opportunities in both the private and public sectors. This has resulted in many unemployed members of the population joining the informal business sector. The majority of people in this sector do not have skills that are needed in the formal employment sector, others are semi-literate and a small percentage has some level of qualification. Nevertheless, this sector is plagued by a number of challenges which this article presents.  The article reports on the study that was conducted at Greater Letaba Municipality in Limpopo Province. The aim of the study was to investigate the challenges that were faced by informal traders in Greater Letaba Municipality in Limpopo Province in South Africa. The area was chosen because of its accessibility to the researchers and its potential to provide relevant and accurate information for the research project. Thus, a qualitative research method was used to collect data through face to face interviews. The research discovered that some of the challenges experienced by the informal traders in the area ranged from lack of support from the local municipality to structural challenges like lack of ablution facilities and limited access to electricity. Furthermore, other challenges concerned safety and health issues that were also gender based. Most of the traders in the area were women; an element which attest to the fact that it is difficult to find employment in the country when one is less educated and is also a woman.

The effects of information conflict, the frequency with which the information is updated, and the reliability of the information sources upon information seeking and decision behavior were studied. Sixteen U. S. Army enlisted men performed a computer-controlled task in which they had to request updated enemy-position reports from three information sources to determine which of eight locations was the target of a gradual enemy advance. Forty problems, presented twice each, were arranged in two within-subject factorial designs-with source reliability varied between and within problems, respectively. Subjects were permitted to make up to three decisions on each problem, with correct decisions rewarded and incorrect decisions penalized according to a non-linear payoff function. Results from analyses of variance indicated that less information was sought prior to an initial decision (a) for higher than for lower reliability conditions, (b) as update frequency decreased, and (c) as degree of conflict increased. When all sources were of higher reliability, accuracy of decisions was higher; but, in general, accuracy was complexly affected by conflict and update frequency. These results were discussed in terms of the cost of requesting information and the probability that an update would contain accurate information. Information sampling and decision latencies as well as other indices of performance were also evaluated and discussed.
