IntroductionToward the Global Vaccine Action Plan 2020 goal, almost 90% of countries have established a National Immunization Technical Advisory Group (NITAG). However, little is known about NITAG's contributions to governance.MethodsIn 2017–2018, a two-step, qualitative retrospective study was conducted. Jordan (JO), Argentina (AR), and South Africa (SA) were selected owing to government-financed NITAGs from middle-income countries (MICs), geographic diversity, and a vaccine introduction with NITAG support. Country case studies were developed, collecting data through desk review and face-to-face key informant interviews (KIIs) from Ministry of Health (MoH) and NITAG. Case studies were analyzed together, to assess governance applying the European Observatory on Health Systems and Policies framework focusing on transparency, accountability, participation, integrity, and policy capacity (TAPIC).ResultsDocument review and 53 KII (22 AR, 20 SA, 11 JO) showed NITAGs played a pivotal role as advisors promoting a culture of evidence-informed policies. NITAGs strengthened governance, although practices varied among countries. Meetings were conducted behind-closed-doors, participation restricted to members, only in one country agendas, and recommendations were public (AR). To increase participation, policy capacity, and transparency, countries considered adding experts in communications, advocacy, and economics. AR and SA contemplated including community members. NITAGs functioned autonomously from the government, with no established internal or external monitoring or supervision. NITAG meeting minutes allowed the review of integrity, adherence to terms of reference, standard operating procedures, and conflict of interest (CoI). For the most part, NITAGs abided by their mandates. Significant issues were related to the level of MoH support and oversight of CoI declaration and documentation.ConclusionsSystematically implementing governance approaches could improve processes, better tailor policies, and implementation. The long-term survival and resilience of NITAGs in these countries showed they play a significant role in strengthening governance. Lessons learned could be useful to those promoting country-driven evidence-informed decision-making. 相似文献

BackgroundTheories of health behavior change are being inadequately adopted to understand the reasons behind low influenza vaccination rates among healthcare workers (HCWs). The Theory of Planned Behavior (TPB) is being used to predict intention-behavior relationship while the Health Belief Model (HBM) is being employed to predict actual behavior. The purpose of this study was to test a conceptual model based on the HBM’s constructs to predict Jordanian HCWs’ intentions for influenza vaccine uptake as an alternative to the TPB.MethodA cross-sectional questionnaire-based study was conducted in 2016 in a tertiary teaching hospital in Amman-Jordan including a convenience sample of 477 HCWs with direct patient contact. The study instrument was tested for validity and reliability. A conceptual regression model was proposed incorporating the constructs of the primary HBM with some modifications in the threat construct as well as an additional variable about explicit past vaccination behavior (in the past year and/or any previous history of influenza vaccine uptake).ResultsAlmost all the constructs of the HBM demonstrated significant differences between participants intending and those who did not intend to vaccinate against influenza. After adjusting for the confounding variables in the final conceptual regression model, past vaccination behavior (OR= 4.50, 95%Confidence Interval 3.38–6.00, P< 0.0005) and the perceived benefit scale (OR= 1.19, 95% Confidence Interval 1.11–1.28, P< 0.0005) were the only significant predictors of intentions to vaccinate against influenza in the next season.ConclusionTaking into consideration the altruistic beliefs of HCWs and their explicit past vaccination history augments the utility of the original HBM tool in predicting HCWs’ intentions to vaccinate against influenza in a way that is consistent with the predictive ability of the Theory of Planned Behavior. 相似文献

Derived relational responding is an increasingly researched topic in the behavioral sciences. Deictic frames, among other forms of relational responding, have been found to underlie complex behavior, including perspective-taking. Researchers have developed procedures for training children, with and without disabilities, to demonstrate relational responding. Recent extensions of these teaching procedures incorporated more naturalistic contexts as an avenue for establishing these repertoires, but the efficacy of these new procedures for children with disabilities and the degree to which these improvements generalize have not yet been explored. The purpose of this study was to determine if relational repertoires could be established using newer, more naturalistic teaching procedures in children diagnosed with an autism spectrum disorder and to what degree improvements would generalize to another adult. Results indicated that all participants met criteria for mastery on all levels of relational complexity. Additionally, all three children demonstrated generalization of these repertoires to a novel adult following training to mastery. The results suggest that an intervention approach utilizing a Barnes-Holmes protocol in a story reading context was effective for establishing deictic repertoires in children diagnosed with an autism spectrum disorder. 相似文献

This paper introduces the ‘foot function’ approach used by podiatrists in the treatment of lower limb musculoskeletal dysfunction. The aim is to demonstrate how podiatric theory has evolved its own perspective of mechanisms relating to normal and abnormal locomotion. Three individual podiatric paradigms are discussed, and a further theory allowing a working simplification of theory is introduced. Finally, an example of gait abnormality is discussed in relation to podiatric and physiotherapy perspectives.An insight into podiatric theory should enable therapists working within this field to develop a more holistic and multidisciplinary approach. It is the view of the authors that a closer working relationship between physiotherapists and podiatrists with an interest in movement dysfunction provides a better quality service for appropriate patients. 相似文献

Background: The bariatric patient exists in dynamic relationship with family members and friends who have considerable influence
upon the patient and his or her surgical outcome. When family members and friends behave as intimate saboteurs, they attempt
to hamper, hurt, or subvert the bariatric patient's goal of achieving and maintaining a healthy body weight. Successful or
not, intimate saboteurs provide significant treatment challenges for the patient and the treatment team. Methods and Patients:
Patient profiles provide examples of intimate sabotage. The psychological construct of Family Systems Theory is used as a
plausible explanation for the sabotage of friends and family. Conclusions: Multidisciplinary professionals treating the bariatric
patient must be aware of the critical influence of intimate saboteurs and the tactics they use to sabotage. Treatment guidelines
recommended by Family Systems Theory are presented as strategies to mitigate the influence of intimate saboteurs. 相似文献
