Reference:Hicks GE, et al Preliminary development of a clinical prediction rule for determining which patients with low back pain will respond to a stabilization exercise program.Arch Phys Med Rehabil. 2005 Sep;86(9):1753-62. The Prone Instability Test has been shown to have good inter-rater reliability and reasonable sensitivity (0.72), meaning if the test is negative.Purpose: Test for the likelihood of a patient responding positively to a spinal stabilization program. Test Position: Prone, Legs fully off plinth resting on floor Performing the Test: With the patient lying prone on a plinth with his legs fully resting on the ground, the examiners places a posterior to anterior pressure in the lumbar spine. The patient then lifts his legs off the floor.To test the interrater reliability of examiners performing the prone instability test (PIT), a clinical test proposed to identify lumbar shear instability. Design Cross-sectional test-retest design examining individuals with mechanical low back pain (LBP).
Whiston (2013) continues on to explain the various types of reliability, including: test-retest, alternate or parallel forms, and internal consistency measures. The designers and authors of the Values and Motives Questionnaire explain that the measurement used internal consistency reliability with the sample (Values and Motives Questionnaire, n.d).
CHAPTER 3 VALIDITY AND RELIABILITY 3 VALIDITY AND RELIABILITY 3.1 INTRODUCTION In Chapter 2, the study’s aims of exploring how objects can influence the level of construct validity of a Picture Vocabulary Test were discussed, and a review conducted of the literature on the various factors that play a role as to how the.
Abstract. The purpose of this study is to reveal the reliability, practicality, and validity level of the entrance exam for the teacher training program at National Institute of Education in Cambodia and to measure the knowledge of the student and test when they did the examination in 2010.

Test-retest reliability is best used for things that are stable over time, such as intelligence. Test-retest reliability is measured by administering a test twice at two different points in time. This type of reliability assumes that there will be no change in the quality or construct being measured.

Test-retest reliability is a measure of reliability obtained by administering the same test twice over a period of time to a group of individuals. The scores from Time 1 and Time 2 can then be correlated in order to evaluate the test for stability over time.
STABILITY TESTING measures the ability of a software product to continue to function, over long period of time, exercising its full range of use, without failing or causing failure. The purpose of Stability Testing is to check if the application will crash at any point in time.

Test-Retest Reliability and Confounding Factors. To give an element of quantification to the test-retest reliability, statistical tests factor this into the analysis and generate a number between zero and one, with 1 being a perfect correlation between the test and the retest. Perfection is impossible and most researchers accept a lower level, either 0.7, 0.8 or 0.9, depending upon the.
What is Reliability? Reliability, on the other hand, is not at all concerned with intent, instead asking whether the test used to collect data produces accurate results. In this context, accuracy is defined by consistency (whether the results could be replicated). The property of ignorance of intent allows an instrument to be simultaneously reliable and invalid.
