Introduction: Addressing the public health problem of physical inactivity, this study evaluates SNapp, a just-in-time adaptive app intervention to promote walking through dynamically tailored coaching content. It assesses SNapp's impact on daily steps and how users' perceptions regarding ease of use and usefulness moderated its effectiveness.

Methods: SNapp was evaluated in an RCT from February 2021 to May 2022.

Real-world nudging, pricing, and mobile physical activity coaching was insufficient to improve lifestyle behaviours and cardiometabolic health: the Supreme Nudge parallel cluster-randomised controlled supermarket trial.

Background: Context-specific interventions may contribute to sustained behaviour change and improved health outcomes. We evaluated the real-world effects of supermarket nudging and pricing strategies and mobile physical activity coaching on diet quality, food-purchasing behaviour, walking behaviour, and cardiometabolic risk markers.

Methods: This parallel cluster-randomised controlled trial included supermarkets in socially disadvantaged neighbourhoods across the Netherlands with regular shoppers aged 30-80 years.

SNapp, a Tailored Smartphone App Intervention to Promote Walking in Adults of Low Socioeconomic Position: Development and Qualitative Pilot Study.

Background: Adults of low socioeconomic position (SEP) are generally less physically active than those who are more socioeconomically advantaged, which increases their cardiovascular disease incidence risk. Moreover, individuals of low SEP are often less easily reached with physical activity (PA) interventions than individuals of higher SEP. Smartphone apps have been presented as a promising platform for delivering PA interventions to difficult-to-reach individuals of low SEP.

Cancer patients' needs for support in expressing instrumental concerns and emotions.

Introduction: The aim of our study was to provide an overview of intervention guidelines on how to address patients' practical needs for support in expressing instrumental concerns and emotions regarding medical, psychosocial and practical topics.

Methods: Six focus groups of cancer patients and survivors (N = 39) were organised. An interview guide was created that consisted of three topics: (a) concerns, (b) needs for support, and (c) a Concern Prompt List.

"I was Right about Vaccination": Confirmation Bias and Health Literacy in Online Health Information Seeking.

When looking for health information, many people turn to the Internet. Searching for online health information (OHI), however, also involves the risk of confirmation bias by means of selective exposure to information that confirms one's existing beliefs and a biased evaluation of this information. This study tests whether biased selection and biased evaluation of OHI occur in the context of early-childhood vaccination and whether people's health literacy (HL) level either prevents or facilitates these processes.

The effects of persuasive messages on cancer patients' attitudes, norms and intention to express concerns.

Objective: To examine whether the use of persuasive messages in which cancer patients' attitudes and perceived social norms were either simultaneously or exclusively targeted can positively change patients' attitudes, perceived social norms and the intention to express concerns in consultations.

Methods: Two online experiments were conducted. The first experiment had a pre-test and post-test measurements design with 4 conditions (attitudes message, social norms message, combined message, control message).

Patients' Online Information-Seeking Behavior Throughout Treatment: The Impact on Medication Beliefs and Medication Adherence.

Research on the longitudinal impact of using the internet as an information source on patients' beliefs and medication adherence is scarce. Chronic patients ( = 107) from six hospitals were surveyed to longitudinally explore their online information seeking behavior throughout treatment (i.e.

Creating a synergy effect: A cluster randomized controlled trial testing the effect of a tailored multimedia intervention on patient outcomes.

Objective: Improving adherence is a challenge and multiple barriers are likely to explain non-adherence. These barriers differ per patient and over course of the regimen. Hence, personalized interventions tailored to the specific barriers are needed.

Dutch health websites and their ability to inform people with low health literacy.

Objective: To evaluate whether Dutch online health information (OHI) generally reflects message elements that support information processing and understanding among people with low health literacy.

Methods: We content-analyzed one hundred Dutch webpages about Ebola, fibromyalgia, ALS, losing weight, borderline personality disorder, hemorrhoids, ADD, bladder infection, shingles, and chicken pox. The codebook covered the following domains: images and videos, readability level, Suitability Assessment of Materials (SAM), advertising, interactive features, and reliability cues.

Understanding the interplay of cancer patients' instrumental concerns and emotions.

Objective: 1) to assess patients' descriptions of concerns, and 2) to inform a conceptual framework in which the impact of the nature of concerns on doctor-patient communication is specified.

Methods: Six focus groups were conducted with 39 cancer patients and survivors. In these focus groups participants were asked to describe their concerns during and after their illness.

Signalling product healthiness through symbolic package cues: Effects of package shape and goal congruence on consumer behaviour.

Three studies show that product packaging shape serves as a cue that communicates healthiness of food products. Inspired by embodiment accounts, we show that packaging that simulates a slim body shape acts as a symbolic cue for product healthiness (e.g.

Framing in Entertainment-Education: Effects on Processes of Narrative Persuasion.

Nowadays, entertainment-education (E-E) is often used as a persuasive strategy to stimulate prosocial behavior. Although E-E is mostly regarded as a persuasive strategy in itself, in an increasing number of E-E programs several persuasive strategies are used to communicate the educational message to the audience. This study investigates the effects of a strategy widely used in health communication, but not previously studied in the field of E-E: framing.

Health Literacy and Online Health Information Processing: Unraveling the Underlying Mechanisms.

The usefulness of the Internet as a health information source largely depends on the receiver's health literacy. This study investigates the mechanisms through which health literacy affects information recall and website attitudes. Using 2 independent surveys addressing different Dutch health websites (N = 423 and N = 395), we tested the mediating role of cognitive load, imagination ease, and website involvement.

Unraveling the Determinants of Cancer Patients' Intention to Express Concerns.

Little is known about the behavioral determinants that underlie cancer patients' intention to express concerns during a consultation. This information can be relevant to developing effective interventions for cancer patients. In this study, the integrative model of behavioral prediction (IMBP) is used as a framework to unravel the determinants of patients' intention to express concerns.

Should We Be Afraid of Simple Messages? The Effects of Text Difficulty and Illustrations in People With Low or High Health Literacy.

It is often recommended that health information should be simplified for people with low health literacy. However, little is known about whether messages adapted to low health literacy audiences are also effective for people with high health literacy, or whether simple messages are counterproductive in this group. Using a two (illustrated vs.

Strategies and motives for resistance to persuasion: an integrative framework.

Persuasion is an important element of human communication. But in many situations, we resist rather than embrace persuasive attempts. Resistance to persuasion has been studied in many different disciplines, including communication science, psychology, and marketing.

Does Media Use Result in More Active Communicators? Differences Between Native Dutch and Turkish-Dutch Patients in Information-Seeking Behavior and Participation During Consultations With General Practitioners.

This study investigates differences between native Dutch and Turkish-Dutch patients with respect to media usage before and patient participation during medical consultations with general practitioners. In addition, the authors assessed the relation between patient participation and communication outcomes. The patients were recruited in the waiting rooms of general practitioners, and 191 patients (117 native Dutch, 74 Turkish-Dutch) completed pre- and postconsultation questionnaires.

The effectiveness of health animations in audiences with different health literacy levels: an experimental study.

Background: Processing Web-based health information can be difficult, especially for people with low health literacy. Presenting health information in an audiovisual format, such as animation, is expected to improve understanding among low health literate audiences.

Objective: The aim of this paper is to investigate what features of spoken health animations improve information recall and attitudes and whether there are differences between health literacy groups.

Educational storylines in entertainment television: audience reactions toward persuasive strategies in medical dramas.

Medical television drama series provide an important source of health information. This form of entertainment-education (E-E) can be used to influence knowledge, attitudes, and behaviors toward health-related issues. In the literature, E-E is generally regarded as a persuasive strategy in itself, whereas in an increasing number of E-E programs, several different persuasive strategies are used.

Patients' reports of barriers to expressing concerns during cancer consultations.

Objective: To identify cancer patients' most influential barriers to expressing concerns during cancer consultations in a new manner by examining patients' reports of perceived barriers and perceived occurrence of barriers in consultations.

Methods: Two online focus groups (N=16) and an online survey (N=236) were conducted among cancer patients and cancer survivors. The online focus groups and survey were used to examine two elements of patients' barriers, i.

The value of nurses' tailored communication when discussing medicines: Exploring the relationship between satisfaction, beliefs and adherence.

Numerous studies of various populations and settings link patient-provider communication or beliefs to medication adherence. A better understanding of this interplay may help to improve patient-centred communication. To predict adherence, this study used the Beliefs about Medicines Questionnaire and indications of the quality of the nurse's communication in terms of patient satisfaction.

May you never forget what is worth remembering: the relation between recall of medical information and medication adherence in patients with inflammatory bowel disease.

Background: Nurses play an important role in educating patients with inflammatory bowel disease (IBD) about immunosuppressive or biological therapy during prescribing consultations. The education for immunosuppressive or biological therapy often contains complex information. Poor medication intake behavior can be a result of poor information recall, which is often caused by complex information.

1+1=3? The systematic development of a theoretical and evidence-based tailored multimedia intervention to improve medication adherence.

Objective: To describe the development of a theoretical and evidence-based tailored multimedia intervention to improve medication intake behavior in patients with inflammatory bowel disease (IBD). The intervention integrates interpersonal and technology-mediated strategies with the expectation that this will work synergistically.

Methods: The development followed the Medical Research Council's framework.

Words that make pills easier to swallow: a communication typology to address practical and perceptual barriers to medication intake behavior.

Purpose: The barriers to patients' successful medication intake behavior could be reduced through tailored communication about these barriers. The aim of this study is therefore (1) to develop a new communication typology to address these barriers to successful medication intake behavior, and (2) to examine the relationship between the use of the typology and the reduction of the barriers to successful medication intake behavior.

Patients And Methods: Based on a literature review, the practical and perceptual barriers to successful medication intake behavior typology (PPB-typology) was developed.
