A Mobile Health Information Behavior Model: Theoretical Development and Mixed-Method Testing in the Context of Mobile Apps on Child Poisoning Prevention.

While several studies have explored the use of mobile health applications, few have observed determinants of mobile health information behavior. To develop a model explaining parents' mobile information behavior on child poisoning prevention, we first explored relevant theories to suggest a theoretical model. In that, we combine existing models on risk and health information seeking, such as the Planned Risk Information Seeking Model, with models on the acceptance of mobile technologies, such as the Unified Theory of Acceptance and Use of Technologies. Thereafter, we employed a sequential mixed-method design with an initial qualitative study (four online focus groups with n = 25 parents in total) and a standardized online survey of n = 1,013 parents to evaluate our research model. Results confirm that both, determinants of information seeking and determinants of technology acceptance, contribute to the explanation of mobile information behavior. App use intention was mainly related to the performance expectancy of app use, the subjective information norm, and social influence on app use. To increase the usage of prevention apps and contribute to the reduction of child injuries, communication on poisoning apps should address subdimensions of the performance expectancy, such as their utility and peoples' trust in app providers. Moreover, physicians are important multipliers for these messages.

[Health information behavior of 65+: reaching older target groups]. / Gesundheitsinformationsverhalten 65+: Erreichbarkeit älterer Zielgruppen.

BACKGROUND: The proportion of older adults among the population is constantly growing. At the same time, the risk of health problems increases with age. From a health promotion perspective, it is therefore important to reach this target group. The selection of media and communication channels should be based on media use and health information behavior of the target group. In this context, it may be necessary to segment the heterogeneous group of older adults into subgroups. OBJECTIVES: The article provides current empirical data on the health information behavior of older adults in general and in particular subgroups. On this basis, adequate communication channels can be selected to address these groups. METHODS: First, 20 people participated in guided qualitative interviews. Second, a subsequent standardized telephone survey of 1001 randomly selected people aged 65 years and above was conducted. RESULTS: Older adults can best be reached via interpersonal and traditional mass media sources. Health-related media such as pharmacy magazines also play an important role, especially for people with chronic diseases. Furthermore, health professionals are also an important source of information for older adults with chronic diseases and a negative attitude towards aging. On the internet, men and people with a higher income are more likely to be reached. CONCLUSIONS: Older adults in Germany are a heterogeneous target group. To reach them effectively, differences in the health information behavior of subtarget groups must be considered. Furthermore, the content and design of communication measures should also be evidence based.

The multi-faceted usage patterns of nutrition apps: a survey on the appropriation of nutrition apps among German-speaking users of MyFitnessPal.

BACKGROUND: Current systematic reviews of randomized controlled trials suggest positive influences of mobile app-based health promotion programs on dietary and physical activity behaviors. However, the actual adoption of and rates of nutrition app use remain low among the overall population. Therefore, we took a step back and investigated actual use patterns. In doing so, we took an appropriation perspective in order to reveal different styles of everyday life integration of these apps. METHODS: We conducted an online survey with 761 German-speaking users of the MyFitnessPal app. Respondents were asked about their detailed use of nutrition apps according to an adapted version of the mobile phone appropriation model. Based on a cluster analysis, different user types were identified. These user types were compared and further described based on analyses of variance. In addition, we conducted a multinomial logistic regression to determine significant predictors of the varying usage patterns. RESULTS: Four different user types were identified: (1) Supported, (2) Indifferent, (3) Health-conscious, and (4) Socializer. These user types mainly differed regarding three aspects: (1) their willingness to adjust default settings to one's own needs and abilities, (2) the role of social support and social norms, and (3) app use for socializing and competition. CONCLUSIONS: Our study sheds light on the multi-faceted appropriation patterns of nutrition apps in Germany, thus paving the way for future studies on mHealth appropriation patterns and the design of more refined mHealth-interventions.

Mobile Apps Aimed at Preventing and Handling Unintentional Injuries in Children Aged <7 Years: Systematic Review.

BACKGROUND: Despite various global health crises, the prevention and handling of unintentional childhood injuries remains an important public health objective. Although several systematic reviews have examined the effectiveness of different child injury prevention measures, these reviews did not address the evaluation of mobile communication intervention tools. Whether and how mobile apps were evaluated provides information on the extent to which communication theories, models, and evidence-based knowledge were considered. Previous studies have shown that the effectiveness of mobile apps increases when theories and evidence are considered during their development. OBJECTIVE: This systematic review aimed to identify research on mobile apps dealing with the prevention and handling of unintentional injuries in children and examine the theoretical and methodological approaches thereof. In addition, this review analyzed the different needs of various target groups of the mobile apps described in the articles. METHODS: In total, 8 electronic databases, ranging from interdisciplinary to medical and technical as well as social sciences databases, were searched for original research articles or brief reports in peer-reviewed journals or conference proceedings. Moreover, this review encompassed a systematic scan of articles published in the BMJ journal Injury Prevention. These steps were followed by a snowball search based on the literature references in the articles identified through the initial screening. The articles had to be written in English or German, published between 2008 and 2021, and evaluate mobile apps dealing with the prevention and handling of unintentional child injuries. The identified 5 studies were analyzed by 5 independent researchers using an inductive approach. Furthermore, the quality of the studies was assessed using the Mixed Methods Appraisal Tool. RESULTS: A total of 5 articles were included and assessed with regard to overall quality of theoretical and methodological foundations, assessed variables, the focal app's architecture, and the needs of the study participants. The overall study quality was moderate, although part of this classification was due to a lack of details reported in the studies. Each study examined 1 mobile app aimed at parents and other caregivers. Each study assessed at least 1 usability- or user experience-related variable, whereas the needs of the included study participants were detailed in only 20% (1/5) of the cases. However, none of the studies referred to theories such as the Technology Acceptance Model during the development of the apps. CONCLUSIONS: The future development and evaluation of apps dealing with the prevention and handling of child injuries should combine insights into existing models on user experience and usability with established theories on mobile information behavior. This theory-based approach will increase the validity of such evaluation studies.

Effective communication with caregivers to prevent unintentional injuries in children under seven years. A systematic review.

OBJECTIVE: This review systematically examines the theory base and effectiveness of communication strategies (i.e., message content, message attributes, communication channels, and communicators) of interventions for caregivers to prevent unintentional child injuries. METHODS: Relevant articles were searched in the databases Communication and Mass Media Complete, PsycInfo, Pubmed, and Google Scholar, the journal Injury Prevention, and the literature of included studies. A total of 71 articles reporting 67 different studies were included and fully coded. Quality was assessed using the Mixed Methods Appraisal Tool. Coded categories and their frequencies are described, and the effectiveness of different communication strategies is explored with crosstabs. RESULTS: Only 17 studies stated the use of a specific theory base; Precaution Adoption Process-Model, Theory of Planned Behavior, and Health Belief Model were most often used. The message content of most studies aimed at knowledge dissemination; however, addressing behavioral determinants, such as risk perception and self-efficacy, was more effective. About half of the studies did not elaborate on message attributes; calls to action, exemplars, and tailoring were most often used, the latter being most effective. Communication channels ranged from printed products to face-to-face communication and digital media. In addition, studies specifying interpersonal communicators were highly effective. CONCLUSION: The results of the review suggest that the following aspects can contribute to effective communication in child injury prevention: theory-based communication, addressing broad knowledge and further behavioral determinants, digital tailoring, and health professionals as communicators. However, a conclusive statement on the effectiveness of different communication strategies is hampered by the fact that they are not specified and/or confounded in many studies. PRACTICE IMPLICATIONS: Communication strategies should be theory based and address, in addition to knowledge, behavioral determinants such as risk perception and self-efficacy. Moreover, digital tailoring is an advanced way of enhancing effectiveness and health professionals, such as pediatricians and clinic staff, are important multipliers.

Determinants of Physical Activity in Older Adults: Integrating Self-Concordance into the Theory of Planned Behavior.

Based on the theory of planned behavior (TPB), augmented by the concept of self-concordance (derived from self-determination theory, SDT), we conducted a study to identify the key determinants of physical activity in older adults. We applied structural equation modeling of telephone survey data from a random sample of adults aged 65 years and older living in Germany (N = 865). Relations of attitude, subjective norms, and perceived behavioral control (PBC) with intention strength and self-concordance of intention to be physically active were tested. Habit strength was analyzed as a moderator. Data analysis showed this model to be well-suited for explaining the intention to be physically active-especially for people with a weak habit. The influence of TPB components on intention would have been underestimated if we had investigated intention strength only, without considering the self-concordance of intention. While attitude and PBC had positive relations with a strong and self-determined intention, the subjective norm showed no relation with intention strength but, rather, with non-self-determined regulation forms. We conclude that the combined model provides a better theoretical foundation from which to explain physical activity intentions than does just one of the theories.

Beliefs and motivation regarding physical activity among older adults in Germany: results of a qualitative study.

Purpose: As the proportion of older adults in Germany continues to grow, so does the need for physical activity as a strategy for health promotion. The purpose of this study is to gain insights into the belief system underlying older adults' physical activity and its interplay with motivation by integrating Theory of Planned Behaviour and Self-Determination Theory.Methods: We conducted 20 semi-structured interviews with residents of Germany who were 65 years of age or older. Transcripts of interviews were analysed with a coding frame of deductive main categories and inductive subcategories.Results: Part of our results is a typology that divides our sample into four groups based on the intensity and perceived sufficiency of their physical activity. These groups mainly differ in their intrinsic vs. extrinsic motivation and how they deal with barriers to physical activity, i.e., control beliefs.Conclusion: Messages to promote physical activity should be tailored regarding older adults' varying beliefs and motivation. To overcome barriers, intrinsic motivation plays a crucial role. Intrinsic motivation is closely linked to activities that are joyful and satisfy basic psychological needs. Moreover, it is important for older adults to be able to adjust their activities to age-related physical limitations and chronic diseases.

Consideraciones para el uso de tramadol en dolor crónico no oncológico en atención primaria de salud (APS)

Introducción: tramadol es un analgésico opioide usado frecuentemente para el manejo del dolor crónico no oncológico (DCNO). En Chile, es parte del arsenal farmacológico de los centros de atención primaria para el tratamiento de patologías como artrosis de cadera y rodilla. Es considerado seguro y efectivo, sin embargo, existen reportes de efectos adversos serios por polimorfismos hepáticos, interacciones farmacológicas, intoxicaciones, adicción y muerte. La dosis óptima de tramadol es paciente dependiente. Por esto, es necesario contar con orientaciones específicas para prescribir tramadol de manera segura y eficaz según las características de cada paciente. Materiales y métodos: se revisaron guías actualizadas, revisiones sistemáticas y guías de sociedades internacionales sobre el uso de opioides en DCNO y el uso de tramadol en patologías de DCNO como artrosis, lumbago crónico, dolor neuropático y fibromialgia. Resultados: tramadol no está indicado en el tratamiento de cuadros de dolor primario como fibromialgia y en DCNO secundario es un fármaco de segunda línea o no está recomendado. En dolor crónico neuropático (DCN) es segunda línea de tratamiento. En osteoartritis de cadera, rodilla y mano, se reporta efecto analgésico modesto. Sopesar riesgos versus beneficios en estos pacientes. En artritis reumatoide y lumbago crónico se desaconseja su uso. Conclusiones: tramadol es un medicamento seguro y efectivo si se indica, administra, supervisa y descontinúa adecuadamente. Sin embargo, puede asociarse a interacciones farmacológicas, efectos secundarios serios, conductas de abuso y usos ilícitos, por lo que es necesario conocer y manejar adecuadamente su farmacología e indicaciones.

Introduction: Tramadol is an opioid pain medicine commonly used for chronic non-cancer pain (CNCP) management. In Chile, it is part of the pharmacological arsenal available in primary care centers for treating specific CNCP pathologies, such as hip and knee arthrosis. Tramadol is considered a safe and effective drug. Nevertheless, there are reports of serious adverse effects of tramadol, such as poisoning, addiction, and death, probably caused by liver polymorphisms and drug interaction. The optimal dose of tramadol is patient-specific. Specific knowledge is needed to prescribe tramadol in a safe and effective way according to the patient's medical backward. Methods: We review updated guidelines, systematic reviews, and guidelines from international societies about the use of opioids and tramadol in CNCP pathologies such as osteoarthritis, chronic low back pain, neuropathic pain, and fibromyalgia. Results: Tramadol has no role in primary pain treatment, such as fibromyalgia, but is a second-line drug for chronic neuropathic pain (CNP) and some secondary pain syndromes. Tramadol has a modest analgesic effect in osteoarthritis patients. Clinicians should always weigh the risks and benefits before prescribing tramadol. Tramadol use is discouraged in rheumatoid arthritis and chronic lumbago. Conclusions: Tramadol is a safe and effective drug if correctly indicated, administered, supervised, and discontinued. However, it may be associated with pharmacological interactions, serious side effects, abuse behaviors, and illicit uses, and it is necessary that clinicians know and manage its pharmacology and indications appropriately.
