Introduction to Test of Independence01:21

Introduction to Test of Independence

2.9K
In statistics, the term independence means that one can directly obtain the probability of any event involving both variables by multiplying their individual probabilities. Tests of independence are chi-square tests involving the use of a contingency table of observed (data) values.
The test statistic for a test of independence is similar to that of a goodness-of-fit test:

Reliability and Validity01:29

Reliability and Validity

13.6K
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.

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Summary

The Timed Up and Go (TUG) test can predict future functional dependency in older adults. Impaired mobility on the TUG test indicates a higher risk, suggesting its utility as a screening tool.

Area of Science:

  • Gerontology
  • Preventive Medicine
  • Biostatistics

Background:

  • Functional dependency is a significant concern for aging populations.
  • Early identification of individuals at risk is crucial for timely interventions.

Purpose of the Study:

  • To evaluate the association between baseline Timed Up and Go (TUG) test results and the occurrence of functional dependency.
  • To determine if TUG test performance can serve as a predictive marker for future care needs.

Main Methods:

  • Analysis of a large cohort (39,519 individuals) from the National Health Insurance Service-Senior Cohort database.
  • Definition of impaired mobility as a TUG test duration of 10 seconds or longer.
  • Utilized Cox proportional hazard regression models to assess risk for functional dependency.

Main Results:

  • Impaired mobility on the TUG test was significantly associated with a higher risk of functional dependency (adjusted HR, 1.65).
  • This association remained significant even in participants with intact baseline activities of daily living.
  • The occurrence rate of dependency was higher in the impaired TUG group compared to the normal group.

Conclusions:

  • The TUG test is a valuable and accessible tool for predicting future functional dependency in older adults.
  • Interventions targeting individuals with impaired TUG test performance may help prevent or delay functional decline and dependency.
