Current Trends in Nursing II

Current Trends in Nursing II

Trends in nursing are multifactorial and associated with changes in society, within the nursing profession, and in other professions. Notably, telehealth and remote nursing contribute to successful healthcare delivery for numerous patients and help reduce stress for nurses due to nursing shortages. Nurses can reach patients, monitor their conditions, and interact with them using computers, audio, visual accessories, and telephones—for example, remote patient monitoring systems. Likewise,...

Social Foundations of Self IV: Self in Digital Communication

Social Foundations of Self IV: Self in Digital Communication

Since the early 2000s, computer-mediated communication (CMC) has grown rapidly, playing a crucial role in self-development. A key distinction between CMC and real-life interactions is the lack of a physically present partner. This absence makes non-verbal cues such as facial expressions, body language, and paralinguistic signals unavailable in CMC platforms like email, instant messaging, or social media. The lack of these cues can create ambiguity and complicate how feedback is interpreted.The...

Social Scripts

People tend to know what behavior is expected of them in specific, familiar settings. A script is a person’s knowledge about the sequence of events expected in a specific setting (Schank & Abelson, 1977). Essentially, scripts are a particular kind of schema, one containing default values for the features within an event. In the restaurant example, the script's features include the props (e.g., tables, menu, food, and money), the roles to be played (e.g., customer and waiter),...

The Sense of Self: Reflected Self-Appraisal and Social Comparison

The Sense of Self: Reflected Self-Appraisal and Social Comparison

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Impact of Social Context on Individuals

Impact of Social Context on Individuals

Social psychology examines how the real or imagined presence of others influences individuals' thoughts, feelings, and behaviors. A key concept in this field is the role of social context in shaping behavior. The same individual may act differently depending on the social setting, due to the varying expectations and norms associated with each environment. This context-dependent behavior illustrates the influence of social roles, which prescribe appropriate conduct in specific situations.Social...

Area of Science:

Public Health
Digital Health
Behavioral Science

Background:

Adults spend substantial time on screen-based activities, some linked to adverse health outcomes.
Understanding contemporary screen time patterns and trends is crucial for public health.
Existing research highlights potential negative physical and psychological impacts of excessive screen use.

Purpose of the Study:

To characterize current patterns of adult screen-based behaviors.
To describe temporal trends in screen time globally, by region, age, sex, and education.
To provide data for health behavior surveillance and research on screen time and health.

Main Methods:

Utilized aggregated data from Global Web Index (GWI) covering 2012-2019.
Analyzed self-reported screen time data from over 2 million adults (16-64 years) across 46 countries.
Examined trends in personal computer, laptop, tablet, mobile phone, broadcast TV, online TV, and games console use.

Main Results:

International daily screen time rose from approximately 9 hours in 2012 to 11 hours in 2019.
Significant increases observed in mobile phone use (+2 hours), online TV viewing (+37 min), and games console use (+26 min).
Greater increases in screen time were noted in Latin America, the Middle East, Africa, and among younger age groups.

Conclusions:

Adult screen time has substantially increased globally between 2012 and 2019.
Screen time trends vary significantly by region and socio-demographic factors, particularly age.
These findings underscore the need for updated health behavior surveillance and research into screen time's health implications.
