Longitudinal Research

13.0K
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...

Bullying02:04

Bullying

8.8K
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...

Prevalence and Incidence01:08

Prevalence and Incidence

1.5K
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Bias in Epidemiological Studies01:29

Bias in Epidemiological Studies

1.2K
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:

Surveys02:16

Surveys

16.6K
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.

Regression Toward the Mean01:52

Regression Toward the Mean

6.8K
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...

Summary

Inconsistent reporting in suicide research, like endorsing suicide plans but denying suicidal ideation, can skew findings. This pattern significantly impacts suicide plan prevalence estimates.

Area of Science:

  • Psychiatry
  • Public Health
  • Epidemiology

Background:

  • Inconsistent reporting in suicidality research can introduce bias.
  • A specific pattern involves endorsing suicide plans while denying suicidal ideation, which is often overlooked.
  • This inconsistency may affect the accurate estimation of suicidality prevalence.

Purpose of the Study:

  • To examine the prevalence of endorsing suicide plans while denying suicidal ideation.
  • To estimate the impact of this reporting inconsistency on suicidality prevalence in the Youth Risk Behavior Survey (YRBS).
  • To assess how excluding such inconsistent reporters affects the prevalence of various suicidality indicators.

Main Methods:

  • Analysis of publicly available Youth Risk Behavior Survey (YRBS) data from 1993 to 2023 (n = 242,403).
  • Examination of four suicidality indicators: active suicidal ideation, suicide plans, suicide attempts, and post-attempt medical treatment.
  • Statistical analyses included proportion tests and Cohen's h to compare prevalence rates.

Main Results:

  • Approximately 3.1% of respondents reported suicide plans while denying suicidal ideation.
  • Excluding these inconsistent reporters systematically altered the prevalence estimates for suicide plans.
  • The prevalence of active suicidal ideation, suicide attempts, and post-attempt medical treatment showed only marginal effects.

Conclusions:

  • The study highlights the significant impact of inconsistent reporting on suicide plan prevalence.
  • Decisions regarding the inclusion or exclusion of participants with conflicting responses require explicit justification.
  • The findings suggest a need to address inconsistent reporting and potentially revise the wording of the suicide plan item for improved validity.
