Surveys

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.

Bullying

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.

Case Studies

Case Studies

There are many research methods available to psychologists in their efforts to understand, describe, and explain behavior and the cognitive and biological processes that underlie it.

Group Design

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 Research

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...

Self-Presentation: Self-Monitoring and Self-Handicapping

Self-Presentation: Self-Monitoring and Self-Handicapping

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about the way you...

Background:

Internet addiction is a growing concern among US college students, yet reliable prevalence data are scarce.
Existing research highlights the need for better understanding of problematic internet usage and its mental health correlates in this demographic.

Purpose of the Study:

To estimate the prevalence of problematic internet usage among US college students.
To investigate the association between problematic internet usage and moderate to severe depression.

Main Methods:

A pilot survey was administered to 307 college students at two US universities.
Participants completed the Internet Addiction Test (IAT) and the Patient Health Questionnaire (PHQ).
Modified Poisson regression was used to assess the association between problematic internet usage and depression.

Main Results:

Out of 224 respondents, 4% reported problematic internet usage, and 12% had moderate to severe depression.
Depressive symptoms were significantly associated with 13 of the 17 individual Internet Addiction Test items analyzed.
Problematic internet usage overall showed a strong association with moderate to severe depression (RR 24.07, P = 0.001).

Conclusions:

Problematic internet usage is a significant concern in US college students, necessitating interventions for vulnerable populations.
While prevalence in this study was lower than some reports, the high-risk population warrants preventative strategies.
Further research is needed to confirm these findings and develop targeted interventions.
