Longitudinal Research02:20

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...
Naturalistic Observations02:30

Naturalistic Observations

If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...
Introduction to Epidemiology01:26

Introduction to Epidemiology

Epidemiology, known as the cornerstone of public health, involves studying the distribution and determinants of health-related events in defined populations and applying these insights to control health issues. This is essential for understanding how diseases spread, identifying populations at greater risk, and implementing measures to control or prevent outbreaks. Epidemiology addresses not only infectious diseases but also non-communicable conditions like cancer and cardiovascular disease,...
Deindividuation00:57

Deindividuation

Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.
Statistical Methods for Analyzing Epidemiological Data01:25

Statistical Methods for Analyzing Epidemiological Data

Epidemiological data primarily involves information on specific populations' occurrence, distribution, and determinants of health and diseases. This data is crucial for understanding disease patterns and impacts, aiding public health decision-making and disease prevention strategies. The analysis of epidemiological data employs various statistical methods to interpret health-related data effectively. Here are some commonly used methods:
Regression Toward the Mean01:52

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...

Summary

Reducing adolescent access to firearms in the Israeli Defense Forces led to a significant 40% decrease in suicide rates. This reduction was primarily observed in firearm suicides over weekends, highlighting policy

Area of Science:

  • Public Health
  • Epidemiology
  • Military Health

Background:

  • Firearm access is a significant risk factor for suicide completion.
  • Adolescent populations, particularly within military settings, are vulnerable to suicide.
  • Previous research indicates a correlation between firearm availability and suicide rates.

Purpose of the Study:

  • To evaluate the impact of a policy restricting adolescent access to firearms on suicide rates.
  • To determine if policy changes in firearm accessibility affect overall suicide trends.
  • To analyze the specific effects on firearm-related suicides versus other methods.

Main Methods:

  • Analysis of suicide rates before and after a policy change in the Israeli Defense Forces.
  • Focus on adolescent populations within the military.
  • Comparison of suicide rates during weekdays and weekends.
  • Examination of suicide methods, specifically firearm use.

Main Results:

  • A significant 40% decrease in overall suicide rates was observed post-policy change.
  • The majority of the reduction was attributed to a decrease in firearm suicides.
  • Suicide rates decreased notably over weekends, with no significant change during weekdays.

Conclusions:

  • Restricting adolescent access to firearms can substantially reduce suicide rates.
  • Policy interventions aimed at limiting firearm availability can have a major impact on public health.
  • Weekend firearm suicide rates are particularly sensitive to access restrictions.
