Bullying02:04

Bullying

A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is bullying.
Surveys02:16

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.
Group Design02:01

Group Design

The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between the two are due to...

Cross-Sectional Research01:50

Cross-Sectional Research

In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

Area of Science:

  • Psychology
  • Public Health
  • Sociology

Background:

  • Internet use is prevalent among young adults.
  • Problematic Internet use (PIU) can negatively impact various aspects of life.
  • Existing research highlights the need for a deeper understanding of PIU's associations.

Purpose of the Study:

  • To investigate the prevalence of problematic Internet use among college students.
  • To examine the relationship between problematic Internet use and health behaviors, psychosocial functioning, and psychiatric comorbidities.

Main Methods:

  • A survey of 2108 college students was conducted.
  • The Internet Addiction Test (IAT) assessed levels of problematic Internet use.
  • The Mini-International Neuropsychiatric Interview (MINI) screened for psychiatric problems.

Main Results:

  • 5.3% of students exhibited moderate to severe problematic Internet use.
  • Higher levels of Internet use were associated with lower Grade Point Average (GPA).
  • Problematic Internet use correlated with less frequent exercise, increased depression symptoms (PHQ-9), and higher perceived stress.

Conclusions:

  • Moderate to severe Internet use is associated with significant psychosocial problems in young adults.
  • The findings underscore the need for further investigation into the links between Internet use, mental health, physical health, and academic outcomes.
