WhatsApp-Based Coaching Program to Support Smoking and Vaping Cessation Among Young People: Pre-Post Study on Acceptance and Preliminary Efficacy

To date, no studies have been conducted on the acceptance or effectiveness of automated Whats App-based smoking cessation programs. Nevertheless, Whats App has characteristics that make it a promising platform for delivering smoking and vaping cessation interventions. In Switzerland, as in many other European countries, Whats App is the most widely used instant messenger and the most used smartphone app among adolescents and young adults [24].

This app's multiple content and delivery options facilitate integrating BCTs into message design. Moreover, Whats App allows documentation of intervention delivery processes, including records of scheduled, sent, read, and answered messages.

A Mindfulness-Based App Intervention for Pregnant Women: Qualitative Evaluation of a Prototype Using Multiple Case Studies

Participants were recruited through instant messaging tools (Whats App [Meta]) and email.

Participants were given oral and written information about the study and provided written informed consent before user testing. At this stage, the Personas methodology was also found useful.

Educational Video Intervention to Improve Health Misinformation Identification on WhatsApp Among Saudi Arabian Population: Pre-Post Intervention Study

Educational Video Intervention to Improve Health Misinformation Identification on WhatsApp Among Saudi Arabian Population: Pre-Post Intervention Study

According to their survey results, Whats App was used by 52.4% (n=144) of health care workers and 51.3% (n=500) of non–health care workers to circulate information. The findings of their study concluded that Whats App is the most commonly used social network among Saudi Arabians. COVID-19–related information is, therefore, more likely to be shared on this application [6].

The Impact of WhatsApp as a Health Education Tool in Albinism: Interventional Study

The Impact of WhatsApp as a Health Education Tool in Albinism: Interventional Study

Among the apps employed in digital health education interventions, Whats App holds a unique position. It is a messenger app that enables users to make voice calls and send instant messages, photos, videos, and voice messages over the internet [10]. In contrast to the original text messaging function on mobile phones, Whats App allows users to send and receive messages at no cost per message [11].

Use and Acceptance of Digital Communication Technology by Older Adults for Social Connectedness During the COVID-19 Pandemic: Mixed Methods Study

Use and Acceptance of Digital Communication Technology by Older Adults for Social Connectedness During the COVID-19 Pandemic: Mixed Methods Study

Videoconferencing apps accounted for most of the positive PU ratings, with the majority (n=22, 88%) of the participants reporting benefits from these apps (eg, Whats App, Zoom). Although the use of these tools did not measure up to in-person activities for older adults, they allowed engagement with friends and family during the pandemic, which was valuable to the participants. I love the quick and easy on-demand nature.
