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.
Relationship Formation02:12

Relationship Formation

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...
Bias in Epidemiological Studies01:29

Bias in Epidemiological Studies

Biases can arise at various stages of research, from study design and data collection to analysis and interpretation. Recognizing and addressing these biases is essential to ensure the validity and reliability of epidemiological findings.Broadly speaking, biases in epidemiology fall into three main categories: selection bias, information bias, and confounding. A more detailed description of possible biases is:
Bystander Effect02:09

Bystander Effect

The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.
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...
Stereotypes, Prejudice, and Discrimination02:55

Stereotypes, Prejudice, and Discrimination

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who are...

Summary

Interview location does not impact participation or accuracy when studying elder violence. Research office or home interviews yield similar prevalence rates for physical, psychological, financial, sexual violence, and neglect in older adults.

Area of Science:

  • Gerontology
  • Public Health
  • Sociology

Background:

  • Assessing violence in the elderly is sensitive, with potential setting influences on participation and accuracy.
  • The study investigated how interview location (home vs. research office) affects violence prevalence data in urban older adults.

Purpose of the Study:

  • To compare participation rates and prevalence estimates of various violence types (physical, psychological, financial, sexual, neglect) among elderly individuals interviewed at home versus a research office.
  • To determine if the interview setting influences the reliability of data on elder violence.

Main Methods:

  • A cohort of 450 urban dwellers aged 60-84 was randomly assigned to home (n=300) or research office (n=150) interviews.
  • Standardized face-to-face interviews were conducted, collecting data on violence experienced in the previous year.
  • Groups were comparable in demographics and behavioral characteristics.

Main Results:

  • Participation rates were similar: 67.0% for home interviews and 70.7% for research office interviews (P=0.431).
  • No significant differences in the prevalence of physical, psychological, financial, sexual violence, or neglect were observed between the two settings.
  • Specific prevalence rates for violence types showed no statistically significant variation based on interview location.

Conclusions:

  • The interview setting (home vs. research office) does not appear to influence participation rates in studies of elder violence.
  • Interview location has no discernible effect on the reported prevalence of different forms of violence among the elderly.
  • Findings suggest flexibility in choosing interview settings for elder violence research without compromising data integrity.
