How Confidence in Prior Attitudes, Social Tag Popularity, and Source Credibility Shape Confirmation Bias Toward Antidepressants and Psychotherapy in a Representative German Sample: Randomized Controlled Web-Based Study.

J Med Internet Res 2019 Apr 23;21(4):e11081. Epub 2019 Apr 23.

Knowledge Construction Lab, Knowledge Media Research Center, Leibniz-Institut für Wissensmedien, Tuebingen, Germany.

Background: In health-related, Web-based information search, people should select information in line with expert (vs nonexpert) information, independent of their prior attitudes and consequent confirmation bias.

Objective: This study aimed to investigate confirmation bias in mental health-related information search, particularly (1) if high confidence worsens confirmation bias, (2) if social tags eliminate the influence of prior attitudes, and (3) if people successfully distinguish high and low source credibility.

Methods: In total, 520 participants of a representative sample of the German Web-based population were recruited via a panel company. Read More

Developing a Physical Activity Ontology to Support the Interoperability of Physical Activity Data.

J Med Internet Res 2019 Apr 23;21(4):e12776. Epub 2019 Apr 23.

Department of Radiological Science, University of California Los Angeles, Los Angeles, CA, United States.

Background: Physical activity data provides important information on disease onset, progression, and treatment outcomes.

Integration of Rehabilitation Activities Into Everyday Life Through Telerehabilitation: Qualitative Study of Cardiac Patients and Their Partners.

J Med Internet Res 2019 Apr 15;21(4):e13281. Epub 2019 Apr 15.

Department of Psychology and Behavioral Sciences, Aarhus University, Aarhus, Denmark.

Clinical Efficacy of Telemedicine Compared with Face-to-face Clinic Visit on Smoking Cessation: A Multi-center, Open-label, Randomized Controlled, Non-inferiority Trial.

J Med Internet Res 2019 Apr 11. Epub 2019 Apr 11.

CureApp Institute, 4136-1 Yokozawa Nagakura, Karuizawa, JP.

Background: Tobacco is a major public health concern. A 12-week standard smoking cessation program is available in Japan; however, its required face-to-face clinic visits has been one of the key obstacles to completing the program, leading to a low smoking cessation success rate. Telemedicine using an internet-based video counseling instead of regular clinic visits could address the obstacles. Read More

Implementation of a Novel Electronic Patient-Directed Smoking Cessation Platform for Cancer Patients: Interrupted Time Series Analysis.

J Med Internet Res 2019 Apr 9;21(4):e11735. Epub 2019 Apr 9.

Princess Margaret Cancer Centre, Toronto, ON, Canada.

Background: Continued smoking in cancer patients undergoing treatment results in significantly higher rates of treatment toxicities and persistent effects, increased risk of recurrence and second malignancy, and increased all-cause mortality. Despite this, routine tobacco use screening and the provision of smoking cessation treatment has yet to be implemented widely in the cancer setting.

Objective: The objective of this study was to implement and evaluate the adoption and impact of an innovative Smoking Cessation e-referral System (CEASE) to promote referrals to smoking cessation programs in cancer patients. Read More

Identification of Anxiety and Depression Symptoms in Patients With Cancer: Comparison Between Short and Long Web-Based Questionnaires.

J Med Internet Res 2019 Apr 5;21(4):e11387. Epub 2019 Apr 5.

Experimental and Clinical Oncology, Department of immunology, genetics and pathology, Uppsala University, Uppsala, Sweden.

Background: Physicians and nurses in cancer care easily fail to detect symptoms of psychological distress because of barriers such as lack of time, training on screening methods, and knowledge about how to diagnose anxiety and depression. National guidelines in several countries recommend routine screening for emotional distress in patients with cancer, but in many clinics, this is not implemented. By inventing screening methods that are time-efficient, such as digitalized and automatized screenings with short instruments, we can alleviate the burden on patients and staff. Read More

Background: The decisions that individuals make about the food and beverage products they purchase and consume directly influence their energy intake and dietary quality and may lead to excess weight gain and obesity. However, gathering and interpreting data on food and beverage purchase patterns can be difficult. Leveraging novel sources of data on food and beverage purchase behavior can provide us with a more objective understanding of food consumption behaviors. Read More

Googling for neurological disorders: from seeking health-related information to patient empowerment, advocacy and open self-disclosure in the Neurology 2.0 era.

J Med Internet Res 2019 Apr 4. Epub 2019 Apr 4.

University of Genoa, Via Antonio Pastore 1, Genova, IT.

Unstructured: The Internet, since its introduction, has played a major role in re-shaping the patient-physician communication and interaction, fostering a shift from a paternalistic to a patient-centered model. Because of its dynamic nature, the Internet has been used a platform not only for disseminating knowledge, facilitated by an improved access to an increasing figure of available resources, but also to spread advocacy, awareness, funding raising and even to openly self-disclosure one's own disease, breaking and removing any taboo. The era of Medicine 2. Read More

Guideline Development for Technological Interventions for Children and Young People to Self-Manage Attention Deficit Hyperactivity Disorder: Realist Evaluation.

J Med Internet Res 2019 Apr 3;21(4):e12831. Epub 2019 Apr 3.

University of Sheffield, Sheffield, United Kingdom.

Background: Attention deficit hyperactivity disorder (ADHD) is a complex neurodevelopmental disorder characterized by inattention, hyperactivity, and impulsivity. ADHD can affect the individual, the individual's family, and the community. ADHD is managed using pharmacological and nonpharmacological treatments, which principally involves others helping children and young people (CAYP) manage their ADHD rather than learning self-management strategies themselves.

To Each Stress Its Own Screen: A Cross-Sectional Survey of the Patterns of Stress and Various Screen Uses in Relation to Self-Admitted Screen Addiction.

J Med Internet Res 2019 Apr 2;21(4):e11485. Epub 2019 Apr 2.

PERFORM Centre, Department of Mathematics and Statistics, Concordia University, Montreal, QC, Canada.

Background: The relationship between stress and screen addiction is often studied by exploring a single aspect of screen-related behavior in terms of maladaptive dependency or the risks associated with the content. Generally, little attention is given to the pattern of using different screens for different types of stressors, and variations arising from the subjective perception of stress and screen addiction are often neglected. Given that both addiction and stress are complex and multidimensional factors, we performed a multivariate analysis of the link between individual's subjective perceptions of screen addiction, various types of stress, and the pattern of screen usage.

Centre for the Development and Evaluation of Complex Interventions for Public Health Improvement, School of Social Sciences, Cardiff University, Cardiff, United Kingdom.

Background: Exercise referral schemes (ERSs) are recommended for patients with health conditions or risk factors. Evidence points to the initial effectiveness and cost-effectiveness of such schemes for increasing physical activity, but effects often diminish over time. Techniques such as goal setting, self-monitoring, and personalized feedback may support motivation for physical activity and maintenance of effects. Read More

Exploring the Challenges of Implementing a Web-Based Telemonitoring Strategy for Teenagers With Inflammatory Bowel Disease: Empirical Case Study.

J Med Internet Res 2019 Mar 29;21(3):e11761. Epub 2019 Mar 29.

Department of Pediatric Gastroenterology, Hepatology and Nutrition, University of Groningen, University Medical Centre Groningen, Groningen, Netherlands.

Background: We designed a telemonitoring strategy for teenagers with inflammatory bowel disease to prevent an anticipated disease flare and avert unplanned office visits and day care procedures. The strategy was evaluated in a randomized controlled trial that involved 11 Dutch pediatric gastroenterology centers, each using repeated symptom scores and stool calprotectin measurements. In the telemonitoring arm of the trial, teenagers (n=84) as well as their health providers were alerted to out-of-range results, and suggestions for change in therapy were offered. Read More
