The Role of Social Network Technologies in Online Health Promotion: A Narrative Review of Theoretical and Empirical Factors Influencing Intervention Effectiveness.

BACKGROUND: Social network technologies have become part of health education and wider health promotion­either by design or happenstance. Social support, peer pressure, and information sharing in online communities may affect health behaviors. If there are positive and sustained effects, then social network technologies could increase the effectiveness and efficiency of many public health campaigns. Social media alone, however, may be insufficient to promote health. Furthermore, there may be unintended and potentially harmful consequences of inaccurate or misleading health information. Given these uncertainties, there is a need to understand and synthesize the evidence base for the use of online social networking as part of health promoting interventions to inform future research and practice. OBJECTIVE: Our aim was to review the research on the integration of expert-led health promotion interventions with online social networking in order to determine the extent to which the complementary benefits of each are understood and used. We asked, in particular, (1) How is effectiveness being measured and what are the specific problems in effecting health behavior change?, and (2) To what extent is the designated role of social networking grounded in theory? METHODS: The narrative synthesis approach to literature review was used to analyze the existing evidence. We searched the indexed scientific literature using keywords associated with health promotion and social networking. The papers included were only those making substantial study of both social networking and health promotion­either reporting the results of the intervention or detailing evidence-based plans. General papers about social networking and health were not included. RESULTS: The search identified 162 potentially relevant documents after review of titles and abstracts. Of these, 42 satisfied the inclusion criteria after full-text review. Six studies described randomized controlled trials (RCTs) evaluating the effectiveness of online social networking within health promotion interventions. Most of the trials investigated the value of a "social networking condition" in general and did not identify specific features that might play a role in effectiveness. Issues about the usability and level of uptake of interventions were more common among pilot studies, while observational studies showed positive evidence about the role of social support. A total of 20 papers showed the use of theory in the design of interventions, but authors evaluated effectiveness in only 10 papers. CONCLUSIONS: More research is needed in this area to understand the actual effect of social network technologies on health promotion. More RCTs of greater length need to be conducted taking into account contextual factors such as patient characteristics and types of a social network technology. Also, more evidence is needed regarding the actual usability of online social networking and how different interface design elements may help or hinder behavior change and engagement. Moreover, it is crucial to investigate further the effect of theory on the effectiveness of this type of technology for health promotion. Research is needed linking theoretical grounding with observation and analysis of health promotion in online networks.

Active assistance technology for health-related behavior change: an interdisciplinary review.

BACKGROUND: Information technology can help individuals to change their health behaviors. This is due to its potential for dynamic and unbiased information processing enabling users to monitor their own progress and be informed about risks and opportunities specific to evolving contexts and motivations. However, in many behavior change interventions, information technology is underused by treating it as a passive medium focused on efficient transmission of information and a positive user experience. OBJECTIVE: To conduct an interdisciplinary literature review to determine the extent to which the active technological capabilities of dynamic and adaptive information processing are being applied in behavior change interventions and to identify their role in these interventions. METHODS: We defined key categories of active technology such as semantic information processing, pattern recognition, and adaptation. We conducted the literature search using keywords derived from the categories and included studies that indicated a significant role for an active technology in health-related behavior change. In the data extraction, we looked specifically for the following technology roles: (1) dynamic adaptive tailoring of messages depending on context, (2) interactive education, (3) support for client self-monitoring of behavior change progress, and (4) novel ways in which interventions are grounded in behavior change theories using active technology. RESULTS: The search returned 228 potentially relevant articles, of which 41 satisfied the inclusion criteria. We found that significant research was focused on dialog systems, embodied conversational agents, and activity recognition. The most covered health topic was physical activity. The majority of the studies were early-stage research. Only 6 were randomized controlled trials, of which 4 were positive for behavior change and 5 were positive for acceptability. Empathy and relational behavior were significant research themes in dialog systems for behavior change, with many pilot studies showing a preference for those features. We found few studies that focused on interactive education (3 studies) and self-monitoring (2 studies). Some recent research is emerging in dynamic tailoring (15 studies) and theoretically grounded ontologies for automated semantic processing (4 studies). CONCLUSIONS: The potential capabilities and risks of active assistance technologies are not being fully explored in most current behavior change research. Designers of health behavior interventions need to consider the relevant informatics methods and algorithms more fully. There is also a need to analyze the possibilities that can result from interaction between different technology components. This requires deep interdisciplinary collaboration, for example, between health psychology, computer science, health informatics, cognitive science, and educational methodology.

Metastatic spinal cord compression: a review of practice and care.

AIM AND OBJECTIVES: The aim of this review was to address: (1) How is spinal stability assessed? (2) What is the role of bracing/should braces be used? (3) When is it safe to mobilise the patient? (4) What position should the patient be nursed in? BACKGROUND: Controversy surrounds the care for patients with metastatic spinal cord compression (MSCC). There is some evidence to indicate that care for patients with MSCC is based on individual clinician preference rather than evidence-based guidelines which has been shown to cause delays and discrepancies in patient treatment. DESIGN: A structured literature review to synthesise the available evidence about the management of MSCC. METHODS: The following databases were searched: Medline, EMBASE, Cochrane Systematic Reviews Database, SIGN (Scottish Intercollegiate Guidelines Network), NICE (National Institute for Clinical Excellence), AMED (Allied and Complementary Medicine), CINAHL (Cumulative Index to Nursing and Allied Health Literature) and BNI (British Nursing Index). Publications were selected from the past 10 years. The search yielded a total of 1057 hits, 755 abstracts were screened, and 73 articles were retrieved and examined. Thirty-five articles were included. RESULTS: The findings identified a gap and evidence relating to spinal stability, bracing, patient mobilisation, and positioning is limited and may be inconclusive. It is important for patients with a poor prognosis that their preferences and quality of life are considered. CONCLUSION: Currently, the evidence base to underpin care is limited, and further research in this area is necessary for patients and healthcare professionals alike. RELEVANCE TO CLINICAL PRACTICE: Patients who suffer from MSCC suffer numerous physical, psychological and social issues. Because of lack of consensus, the current guidelines to inform clinical decision-making of professional staff are of limited benefit.

Qualitative meta-synthesis of user experience of computerised therapy for depression and anxiety.

OBJECTIVE: Computerised therapies play an integral role in efforts to improve access to psychological treatment for patients with depression and anxiety. However, despite recognised problems with uptake, there has been a lack of investigation into the barriers and facilitators of engagement. We aimed to systematically review and synthesise findings from qualitative studies of computerised therapies, in order to identify factors impacting on engagement. METHOD: Systematic review and meta-synthesis of qualitative studies of user experiences of computer delivered therapy for depression and/or anxiety. RESULTS: 8 studies were included in the review. All except one were of desktop based cognitive behavioural treatments. Black and minority ethnic and older participants were underrepresented, and only one study addressed users with a co-morbid physical health problem. Through synthesis, we identified two key overarching concepts, regarding the need for treatments to be sensitive to the individual, and the dialectal nature of user experience, with different degrees of support and anonymity experienced as both positive and negative. We propose that these factors can be conceptually understood as the 'non-specific' or 'common' factors of computerised therapy, analogous to but distinct from the common factors of traditional face-to-face therapies. CONCLUSION: Experience of computerised therapy could be improved through personalisation and sensitisation of content to individual users, recognising the need for users to experience a sense of 'self' in the treatment which is currently absent. Exploiting the common factors of computerised therapy, through enhancing perceived connection and collaboration, could offer a way of reconciling tensions due to the dialectal nature of user experience. Future research should explore whether the findings are generalisable to other patient groups, to other delivery formats (such as mobile technology) and other treatment modalities beyond cognitive behaviour therapy. The proposed model could aid the development of enhancements to current packages to improve uptake and support engagement.

A typology of knowledge for district nursing assessment practice.

BACKGROUND: This paper reports on part of a larger study, the aim of which was to explore the nature of knowledge required by district nurses (DNs) to carry out first assessment visits, and the relationship of this to the decisions they make. Assessment of need is a key and complex component of the DN role. To date, there has been limited exploration of the knowledge underpinning needs assessment in district nursing practice. AIM: The aim of this paper is to identify and categorize the knowledge in use by DNs undertaking first assessment visits, by presenting it in the form of the typology of knowledge which emerged from the study. METHODS: The study used a qualitative, ethnographic design. Eleven DNs were observed undertaking first assessment visits and interviewed twice: following the observed visit and 1 year later, after preliminary data analysis had been undertaken. Approaches to analysis were data driven, and constructing the typology involved uncovering and linking what the DN was seeing, asking and doing. Data were collected during 1997 and 1998. FINDINGS: The findings revealed a breadth and depth of community nursing knowledge that seemed to incorporate an amalgam of theoretical (knowing that) and practice-based (knowing how) knowledge. The findings depict the range and scope of the knowledge in use by the DNs, and challenge the utility of theoretical models that remove knowledge from the context in which it is used and applied. CONCLUSION: The findings presented here provide fresh insight into the 'know-how' of district nursing assessment practice. Whilst the typology requires further testing and refinement in order to enhance understanding of practice, it conceptualizes aspects of district nursing assessment knowledge and addresses the current lack of underpinning principles in district nursing practice.

The work of district nurses: first assessment visits.

BACKGROUND: District nurses are the largest group of community nurses in the United Kingdom and overall responsibility for assessing and planning how patients' and families' needs are met remains an essential element of their role. AIM: To explore the nature of the knowledge required by district nurses to carry out first assessment visits and the relationship of this to the decisions they make. METHODS: An ethnographic design was used. The sample was 11 district nurses and the principal data collection methods were participant observation and two semi-structured interviews. The first interview, which took place immediately after the visit, was designed to explore general areas in relation to assessment and particular issues from the visit (phase 1). Following analysis of the phase 1 interview and fieldnote data, questions for the second interview were generated to facilitate further exploration and clarification of important issues that had arisen (phase 2). The second interviews were conducted approximately 1 year later and data were collected during 1997 and 1998. FINDINGS: The findings revealed a breadth and depth of community nursing knowledge that seemed to incorporate an amalgam of theoretical (knowing that) with practice-based (knowing how) knowledge. The findings depict the range and scope of knowledge in use by district nurses and reflexive character of the assessment process, and challenge the use of theoretical models that remove knowledge from the context in which district nurse-patient interactions take place. CONCLUSION: The information search in assessment was paced to cope with the uncertainty that existed in many of the complex multifaceted situations encountered by the district nurses. Understanding assessment as a paced process was linked to making the best judgement at the time of the visit.
