Guidelines and Recommendations for Developing Interactive eHealth Apps for Complex Messaging in Health Promotion.

BACKGROUND: The now ubiquitous catchphrase, "There's an app for that," rings true owing to the growing number of mobile phone apps. In excess of 97,000 eHealth apps are available in major app stores. Yet the effectiveness of these apps varies greatly. While a minority of apps are developed grounded in theory and in conjunction with health care experts, the vast majority are not. This is concerning given the Hippocratic notion of "do no harm." There is currently no unified formal theory for developing interactive eHealth apps, and development is especially difficult when complex messaging is required, such as in health promotion and prevention. OBJECTIVE: This paper aims to provide insight into the creation of interactive eHealth apps for complex messaging, by leveraging the Safe-D case study, which involved complex messaging required to guide safe but sufficient UV exposure for vitamin D synthesis in users. We aim to create recommendations for developing interactive eHealth apps for complex messages based on the lessons learned during Safe-D app development. METHODS: For this case study we developed an Apple and Android app, both named Safe-D, to safely improve vitamin D status in young women through encouraging safe ultraviolet radiation exposure. The app was developed through participatory action research involving medical and human computer interaction researchers, subject matter expert clinicians, external developers, and target users. The recommendations for development were created from analysis of the development process. RESULTS: By working with clinicians and implementing disparate design examples from the literature, we developed the Safe-D app. From this development process, recommendations for developing interactive eHealth apps for complex messaging were created: (1) involve a multidisciplinary team in the development process, (2) manage complex messages to engage users, and (3) design for interactivity (tailor recommendations, remove barriers to use, design for simplicity). CONCLUSIONS: This research has provided principles for developing interactive eHealth apps for complex messaging as guidelines by aggregating existing design concepts and expanding these concepts and new learnings from our development process. A set of guidelines to develop interactive eHealth apps generally, and specifically those for complex messaging, was previously missing from the literature; this research has contributed these principles. Safe-D delivers complex messaging simply, to aid education, and explicitly, considering user safety.

Young people's difficulty in talking to others about mental health problems: An analysis of time trends in Switzerland.

The article aimed to analyse time trends regarding young people's willingness to talk about mental health problems. Data on 16,774 participants (16-20-year olds) of the 'Swiss Multicentre Adolescent Survey on Health' (SMASH) were analysed. The survey was conducted in 1992/93 and in 2002. Logistic regression analyses were conducted to identify predictors associated with the self-reported willingness of youth to talk about mental health problems with adults (other than parents), friends or no one. Socio-demographic characteristics were used as covariates. These analyses were first carried out for the total sample and, in a second step, stratified by suicidality of the participants. The percentage of participants who would talk about mental health problems with adults or friends increased between 1992/93 and 2002, while the percentage of those who would not talk about such problems decreased. This pattern was confirmed in the stratified analyses (i.e., for suicidal and non-suicidal individuals). Hence, Swiss youth seem to have less difficulty in talking with others about mental health problems than previous cohorts. This trend towards increased disclosure may have implications for claims that the prevalence of mental health problems has increased in recent decades.

Prevalence of depression and its correlates among undergraduates in Sri Lanka.

AIMS: There is a dearth of mental health research on undergraduates in Sri Lanka. This study examines the prevalence of depression in a sample of Sri Lankan undergraduates, their exposure to threatening life events and the predictors of their depression. METHODS: Responses of 4304 undergraduates were obtained on the Patient Health Questionnaire-9 and a measure of exposure to threatening life events, with binary logistic regression models used to identify the demographic and life event correlates of screening positive for Major Depressive Disorder (MDD). RESULTS: PHQ-9 diagnoses of 'Major' and 'Other' depression were obtained by 9.3% and 13.5% of undergraduates, respectively. A higher likelihood of MDD was seen among those who were older and those living in hostels (compared to home), although no differences were seen between genders or those studying in different faculties. Likelihood of MDD was higher in undergraduates exposed to multiple threatening life events as well as those exposed to physical threat; family deaths; romantic break-ups; a problem with a close associate; educational difficulties; unemployment and domestic violence, and among male undergraduates harassed by another student. CONCLUSIONS: MDD is prevalent in these undergraduates and universities need to develop services to assist them. Such services may also need to focus on supporting those who have experienced threatening life events, particularly those that arise as a result of being an undergraduate, as these may increase the risk of MDD.
