Theoretical Approaches to Psychological Disorder01:29

Theoretical Approaches to Psychological Disorder

278
The development of psychological disorders, which are characterized by deviant, maladaptive, and personally distressing behaviors, has been explored through several theoretical approaches.
Biological approach
The biological approach posits that internal, organic factors are the primary causes of such disorders. This perspective emphasizes brain structure and function, genetic predispositions, and neurotransmitter imbalances. For example, schizophrenia has been associated with both genetic...

Mechanistic Models: Overview of Compartment Models

144
Mechanistic models, a category encompassing both physiological and compartmental modeling, differ from empirical models' approaches to incorporating known factors about the systems being modeled. Empirical models describe data with minimal assumptions, while mechanistic models aim to provide a robust description of available data by specifying assumptions and integrating known factors about the system. Compartmental analysis is a key example of a mechanistic model in pharmacokinetics and...

Mechanistic Models: Compartment Models in Individual and Population Analysis

79
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...

Pharmacokinetic Models: Overview

991
Pharmacokinetic models utilize mathematical analysis to achieve a detailed quantitative understanding of a drug's life cycle within the body. They are instrumental in simulating a drug's pharmacokinetic parameters, predicting drug concentrations over time, optimizing dosage regimens, linking concentrations with pharmacologic activity, and estimating potential toxicity.
There are three primary types of models: empirical, compartment, and physiological. Empirical models, with minimal...

Models of Health Promotion and Illness Prevention I

2.1K
A model is a theoretical way to understand a concept or an idea. Models can overcome barriers to health regardless of diverse economic and cultural backgrounds. In addition, models make the task easier by providing different ways to approach complex issues. There are two major health promotion models: the health belief model and the health promotion model.
The health belief model (HBM) attempts to predict health-related behavior in specific belief patterns. According to the HBM, a person's...

Pharmacokinetic Models: Comparison and Selection Criterion

132
Physiological and compartmental models are valuable tools used in studying biological systems. These models rely on differential equations to maintain mass balance within the system, ensuring an accurate representation of the dynamic processes at play.
Physiological models take a detailed approach by considering specific molecular processes. They can predict drug distribution, metabolism, and elimination changes, providing a comprehensive understanding of how drugs interact with the body.

Area of Science:

  • Neurology
  • Pain Medicine
  • Psychiatry

Background:

  • Tension-type headache (TTH) is a common yet poorly understood pain condition.
  • Multiple factors are believed to contribute to TTH pathogenesis.
  • Existing models do not fully capture the complexity of TTH.

Purpose of the Study:

  • To compare competing multivariate pathway models explaining TTH complexity.
  • To identify key factors influencing TTH disability.
  • To develop a data-driven model for TTH research.

Main Methods:

  • Collected data on headache features, disability, anxiety, depression, sleep quality, pressure pain thresholds (PPTs), and trigger points (TrPs) from 208 TTH individuals.
  • Utilized Structural Equation Modelling (SEM) and Bayesian Network (BN) analyses.
  • Compared a theoretical model (modeltheory) with a data-driven model (modelBN).

Main Results:

  • The data-driven model (modelBN) demonstrated a superior statistical fit (RMSEA=0.035) compared to the theoretical model (RMSEA=0.094).
  • The strongest association in modelBN was between Distress (psychological factors) and Disability (β=1.524, P=.006).
  • ModelBN highlighted poor sleep, psychological factors, and pain duration as significant influences on disability, differing from modeltheory.

Conclusions:

  • A data-driven model provides a more accurate representation of TTH complexity than a theoretical model.
  • Psychological factors, sleep quality, and pain duration are critical in TTH disability.
  • The data-driven model can inform clinical trials for TTH treatment strategies.
