A qualitative study of user perceptions of mobile health apps

BackgroundMobile apps for health exist in large numbers today, but oftentimes, consumers do not continue to use them after a brief period of initial usage, are averse toward using them at all, or are unaware that such apps even exist. The purpose of our study was to examine and qualitatively determine the design and content elements of health apps that facilitate or impede usage from the users’ perceptive.MethodsIn 2014, six focus groups and five individual interviews were conducted in the Midwest region of the U.S. with a mixture of 44 smartphone owners of various social economic status. The participants were asked about their general and health specific mobile app usage. They were then shown specific features of exemplar health apps and prompted to discuss their perceptions. The focus groups and interviews were audio recorded, transcribed verbatim, and coded using the software NVivo.ResultsInductive thematic analysis was adopted to analyze the data and nine themes were identified: 1) barriers to adoption of health apps, 2) barriers to continued use of health apps, 3) motivators, 4) information and personalized guidance, 5) tracking for awareness and progress, 6) credibility, 7) goal setting, 8) reminders, and 9) sharing personal information. The themes were mapped to theories for interpretation of the results.ConclusionsThis qualitative research with a diverse pool of participants extended previous research on challenges and opportunities of health apps. The findings provide researchers, app designers, and health care providers insights on how to develop and evaluate health apps from the users’ perspective.

Qualitative Interviews With Science Communication Trainers About Communication Objectives and Goals

Qualitative interviews with science communication trainers (n = 24) on the role of objectives and goals in training efforts suggest that trainers believe that scientists come to training with a range of long-term goals in mind. However, trainers appear to focus on teaching communication skills and are relatively unlikely to focus on identifying specific communication objectives as a means of achieving scientists’ goals. The communication objective that trainers consistently report emphasizing is knowledge building. Other potential objectives such as fostering excitement, building trust, and reframing issues were rarely raised. Research aimed at helping trainers foster strategic communication capacity is proposed.

What do they like? Communication preferences and patterns of older adults in the United States: The role of technology

ABSTRACT With the development of information and communication technologies (ICTs), there are increasingly more Internet-based communication methods available for older adults besides traditional methods (e.g., in-person or landline phone). However, older adults’ preferred communication methods remain under-investigated. The purpose of this study is to explore the communication preferences and patterns of older adults in the United States, with emphasis on technologically-mediated environments. In this study, 17 semistructured interviews were conducted with participants from a midwestern state in the United States. The goal was to examine older adults’ communication patterns and preferences with family members and friends, as well as their views about the impacts of modern technology on communication. Three themes (communication preferences and reasons, communication barriers, and the impacts of technology) were generated from the interviews. The findings showed that although face-to-face communication is the most preferred method, telephone communication is the most commonly adopted method. Interviewees also shared different opinions regarding Internet-based communication. The current study illustrated the importance of understanding the preferences and patterns of older adults’ communication needs and desires.

Take a Break Examining College Students’ Media Multitasking Activities and Motivations During Study- or Work-Related Tasks

A survey (N = 524) examined how frequently college students engage in multitasking with social media, texting/instant messaging (IM), and music while studying/working and what motivates them to multitask with each medium. Four out of five participants multitasked with Facebook and texting/IM, and two out of three multitasked with music. Habit was the strongest motivation for multitasking that positively predicted multitasking frequency. Overall, multitasking with Facebook, texting/IM, and music differed by motivations. Multitasking with music was associated with entertainment and efficiency needs, while multitasking with Facebook/texting/IM was related to satisfying socialization, passing time, and escaping needs.

Exploring the Challenges and Opportunities of Health Mobile Apps for Individuals with Type 2 Diabetes Living in Rural Communities

BACKGROUND Many adults with type 2 diabetes (T2D), living in rural communities, are not optimally managing the disease through their diet and physical activities. Mobile apps have the potential to facilitate self-management activities, such as providing educational content, assisting with problem solving, and self-regulation. The goal of this study was to understand the perceived barriers, benefits, and facilitators among rural adults with T2D regarding the use of free mobile apps available in Apple App store or Google Play store for diabetes management or behavior monitoring. MATERIALS AND METHODS Four focus groups were conducted with 18 participants with T2D who owned a smartphone (age: M = 54.4, SD = 12.7; 27.8% male). The participants were asked about their general app and health-specific app usage. They were then shown features of four apps related to diabetes self-management (Glucose Buddy, mySugr, MyFitnessPal, and MapMyWalk) and prompted to provide feedback. The focus groups were audio recorded, transcribed verbatim, and coded using inductive thematic analysis. RESULTS Four themes were identified as follows: (1) perceived barriers to use or continuous use, (2) perceived benefits of desired features of diabetes self-management, (3) facilitators to motivate use, and (4) information sharing with family, friends, and health professionals. CONCLUSIONS The findings provide initial user perceptions regarding the feasibility and acceptability of mobile apps for T2D self-management. These findings regarding perceived barriers, benefits, and facilitators can guide the development and design of apps for individuals with T2D and help researchers determine best practices when developing apps for other chronic conditions.

Double-Dipping Effect? How Combining YouTube Environmental PSAs With Thematically Congruent Advertisements in Different Formats Affects Memory and Attitudes

An online experiment (N = 303) explored the effects of ad-video thematic congruence and ad format on recall and recognition for and attitudes toward persuasive environmental videos and paid commercials on YouTube. Pairing YouTube videos with congruent advertisements enhanced recall for both messages and recognition for advertisements. Congruent in-stream commercials were the strongest in affecting recognition of advertising contents. A negative congruence effect occurred in evaluations of advertised companies where companies in congruent ads were rated less favorably. In-stream advertisements elicited better memory for persuasive messages but less favorable attitudes toward companies and environmental organizations. Overall, advertisements and advertised companies elicited more positive attitudes than environmental videos and environmental organizations.

If I choose when to switch

The present study explored the effects of switching between reading an online article and checking Facebook on recognition memory, moderated by polychronicity, or preference for multitasking. The results of the study indicated that participants recognized online information less efficiently when they were required to check Facebook (forced multitasking) and when they could choose to check Facebook if and when they wanted (voluntary multitasking) compared with the control, non-multitasking, condition. I.e., the opportunity to multitask interfered with the efficiency of online information processing as much as actual multitasking. Polychronicity was a significant moderator of the multitasking effects. Low polychronics were negatively affected by multitasking to a greater extent than high polychronics. Their article recognition levels were lower than those of high polychronics. Two recognition measures derived from the signal detection theory: recognition sensitivity and criterion bias, were used. The study indicated that forced and voluntary multitasking affected high and low polychronics differently. Low polychronics showed greater cognitive effort than high polychronics when they engaged in voluntary media multitasking, while the amount of cognitive resources allocated to processing increased in high polychronics in the non-multitasking (control) condition. When high polychronics did not have control over switching to Facebook (forced multitasking), their recognition of the online article content decreased. Theoretical, methodological, and managerial implications of the study are discussed. Opportunity to multitask interfered with memory as much as actual multitasking.Multitasking negatively affected low polychronics more than high polychronics.Recognition increased in high polychronics who had control over using Facebook.Low polychronics showed higher cognitive effort during voluntary multitasking.High polychronics showed higher cognitive effort in the nonmultitasking condition.

Two-Way Communication between Scientists and the Public: A View from Science Communication Trainers in North America.

ABSTRACT The current study explores the degree to which two-way communication is applied in science communication contexts in North America, based on the experiences of science communication trainers. Interviews with 24 science communication trainers suggest that scientists rarely focus on applying two-way communication tactics, such as listening to their audiences or tailoring messages based on their audiences’ needs. Also, although trainers generally recognize the value of two-way communication, it is seldom addressed in science communication trainings. The importance of two-way communication in fostering interactive dialogical communication between scientists and the public, and thus the importance of emphasizing it more during science communication training, is discussed.

Scientists’ views about communication objectives:

This study looks at how United States–based academic scientists from five professional scientific societies think about eight different communication objectives. The degree to which scientists say they would prioritize these objectives in the context of face-to-face public engagement is statistically predicted using the scientists’ attitudes, normative beliefs, and efficacy beliefs, as well as demographics and past communication activity, training, and past thinking about the objectives. The data allow for questions about the degree to which such variables consistently predict views about objectives. The research is placed in the context of assessing factors that communication trainers might seek to reshape if they wanted get scientists to consider choosing specific communication objectives.

Does being a jerk work? Examining the effect of aggressive risk communication in the context of science blogs

Understanding aggressive risk communication is important because many scientists use this approach and we know little about its effects. Two studies were conducted to assess the effect of exposure to aggressive risk communication by a scientist on respondents’ perceptions of risk communication quality, supportive behavior (i.e. forwarding the communication), risk communicator likability, and overall views about scientists. Perceived aggressiveness (studies 1–2) and expectation violation (study 2) were considered as mediators. Analyses suggest both direct and indirect negative effects of aggressive risk communication in the case of likability but potentially positive effects in terms of evaluating the message quality. Moreover, expectation violation provided one possible explanation for the effect of aggression.
