Reliability and Validity01:29

Reliability and Validity

13.7K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Statistical Analysis: Overview

14.0K
When we take repeated measurements on the same or replicated samples, we will observe inconsistencies in the magnitude. These inconsistencies are called errors. To categorize and characterize these results and their errors, the researcher can use statistical analysis to determine the quality of the measurements and/or suitability of the methods.
One of the most commonly used statistical quantifiers is the mean, which is the ratio between the sum of the numerical values of all results and the...

Kendall's Coefficient of Concordance01:20

Kendall's Coefficient of Concordance

915
Kendall's Coefficient of Concordance (W), also known as Kendall's W, is a non-parametric statistical measure used to assess the agreement or concordance between multiple raters or judges when they rank a set of items. It is often used when you have ordinal data (ranks) and you want to see if there is consistency or consensus among the raters. It is widely applied in research areas such as psychology, medicine, and social sciences, where multiple judges are asked to rank or rate subjects...

Group Design

10.1K
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...

Bioequivalence Experimental Study Designs: Repeated Measures, Cross-Over, Carry-Over, and Latin Square Designs

162
Body:Bioequivalence experimental study designs play a pivotal role in testing the effectiveness of various treatments. Key among these are the repeated measures, cross-over, carry-over, and Latin square designs. In the repeated measures design, each subject receives all treatments, allowing for temporal comparisons. This type of design is useful in reducing variability but requires careful planning to avoid bias.The cross-over design, an economical method, involves sequential administration of...

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...

Área de la Ciencia:

  • Psicología
  • Psicología Cuantitativa
  • Psicometría

Sus antecedentes:

  • La fiabilidad entre evaluadores es esencial en la investigación psicológica.
  • Los modelos existentes a menudo luchan con tipos de evaluadores estructuralmente diferentes (por ejemplo, autoinformes frente a informes de pareja).
  • Necesidad de métodos para evaluar la consistencia del evaluador específica de la persona y sus predictores.

Objetivo del estudio:

  • Proponer un modelo novedoso de series temporales latentes multinivel (MR-MLTS) para datos intensivos longitudinales con evaluadores múltiples y estructuralmente diferentes.
  • Permitir la estimación de coeficientes de consistencia del evaluador idiográficos (específicos de la persona).
  • Facilitar la vinculación de la consistencia del evaluador con variables externas.

Principales métodos:

  • Desarrollo de un modelo de series temporales latentes multinivel (MR-MLTS).
  • Implementación del modelo en Mplus y un nuevo paquete de R (mlts).
  • Aplicación del modelo a datos intensivos longitudinales de 100 parejas heterosexuales (86 puntos de tiempo).

Principales resultados:

  • La duración de la relación y los recursos cognitivos de la pareja predicen positivamente la consistencia del evaluador para las innovaciones.
  • Los resultados de la simulación resaltan la importancia del número de puntos de tiempo para estimar los coeficientes idiográficos.
  • El número de participantes es crucial para recuperar las varianzas de los efectos aleatorios.

Conclusiones:

  • El modelo MR-MLTS ofrece un enfoque flexible para cuantificar el acuerdo entre evaluadores en estudios diádicos y longitudinales complejos.
  • Los hallazgos subrayan el papel de los factores de relación en la configuración de la consistencia del evaluador.
  • El modelo proporciona información valiosa sobre la precisión de la medición y las diferencias individuales en el acuerdo.
