Introduction to Stress and Lifestyle01:27

Introduction to Stress and Lifestyle

666
Stress is a multifaceted response to events perceived as challenging or threatening, highlighting physical, emotional, cognitive, and behavioral reactions. Physically, stress can lead to fatigue, sleep disruptions, and various health issues such as frequent colds, chest pains, and nausea. Emotionally, it can manifest as anxiety, depression, irritability, and anger triggered by both minor and major life events. Cognitively, it may result in difficulty in concentration, memory, and...

Mechanistic Models: Compartment Models in Individual and Population Analysis

285
Mechanistic models are utilized in individual analysis using single-source data, but imperfections arise due to data collection errors, preventing perfect prediction of observed data. The mathematical equation involves known values (Xi), observed concentrations (Ci), measurement errors (εi), model parameters (ϕj), and the related function (ƒi) for i number of values. Different least-squares metrics quantify differences between predicted and observed values. The ordinary least...

Pharmacodynamic Models: Additive and Proportional Drug Effect Model

18
Drug response models describe how pharmacological agents interact with biological systems to produce measurable effects. Baseline responses are inherent physiological activities without a drug significantly influencing the observed pharmacological outcomes. Depending on the drug response model employed, these baseline responses may combine with the drug's effect in either an additive or proportional manner.Additive Drug Response ModelIn the additive model, the drug effect is independent of the...

Assumptions of Survival Analysis

438
Survival models analyze the time until one or more events occur, such as death in biological organisms or failure in mechanical systems. These models are widely used across fields like medicine, biology, engineering, and public health to study time-to-event phenomena. To ensure accurate results, survival analysis relies on key assumptions and careful study design.

Parametric Survival Analysis: Weibull and Exponential Methods

1.1K
Parametric survival analysis models survival data by assuming a specific probability distribution for the time until an event occurs. The Weibull and exponential distributions are two of the most commonly used methods in this context, due to their versatility and relatively straightforward application.
Weibull Distribution
The Weibull distribution is a flexible model used in parametric survival analysis. It can handle both increasing and decreasing hazard rates, depending on its shape parameter...

Noncompartmental Analysis: Statistical Moment Theory

438
Noncompartmental analyses leverage statistical moment theory to examine time-related changes in macroscopic events, encapsulating the collective outcomes stemming from the constituent elements in play. Statistical moment theory is a mathematical approach used to describe the time course of drug concentration in the body without assuming a specific compartmental model. SMT provides insights into drug absorption, distribution, metabolism, and elimination by treating drug concentration versus time...

Summary

Two distinct affect profiles emerged in students vicariously exposed to terrorism. One profile showed lower positive affect and higher negative affect, linked to lower conscientiousness and higher neuroticism.

Area of Science:

  • Psychology
  • Psychiatry
  • Data Science

Background:

  • Affect is a complex, nonlinear dynamic process.
  • Understanding affect profiles in populations exposed to trauma is crucial.
  • Vicarious exposure to terrorism can significantly impact psychological well-being.

Purpose of the Study:

  • To identify distinct affect profiles over time in university students vicariously exposed to terrorism.
  • To examine the relationship between identified affect profiles and personality traits (Big Five).
  • To apply latent class extended mixed models (LCMM) for uncovering unobserved groupings in longitudinal affect data.

Main Methods:

  • Utilized latent class extended mixed models (LCMM) with R.
  • Analyzed longitudinal affect data from 193 university students over seven days post-terrorism attacks.
  • Assessed Big Five personality traits and antecedents of affect.

Main Results:

  • Identified two distinct affect profiles among students influenced by terrorism (33% of sample).
  • Profile 1: Lower positive affect, higher negative affect; associated with lower conscientiousness and higher neuroticism.
  • Profile 2: Higher positive affect, lower negative affect; associated with higher conscientiousness and lower neuroticism.

Conclusions:

  • Affective responses to vicarious terrorism exposure can be distinctly profiled over time.
  • Personality traits, specifically conscientiousness and neuroticism, are associated with different affect profiles.
  • Findings offer theoretical insights into dynamic affect processes and practical implications for psychological support.
