Testretest reliability is conducting the same test with the same respondents at different moments of time. For example, a group of participants is given a personality test and then are given the same is tested at a later time, Dec 19, 2009 The types of reliability used consist of testretest reliability and internal consistency where the types of validity that were used are construct validity and criterion validity (vmiman).
The testretest reliability is an assessment of the similarity of scores on a particular scale over two or more test occasions. Types of Reliability The criterion of reliability is the consistency or stability, but it may also imply dependability. The different types of reliability are: Alternateform reliability, Itemtoitem reliability, and Testretest reliability. Interrater reliability of the Berg Balance Scale, 30 s chair stand test and 6 m walking test, and construct validity of the Berg Balance Scale in nursing home residents with mildtomoderate dementia Berg Balance Test.
Overview and Statistics. Purpose: 14item test that assesses static standing balance and subsequent fall risk. Diagnoses Assessed: Stroke; SCI's; Testretest reliability. 77; Intrarater reliability. 97; Interrater reliability. 88; Berg Balance Test Instructions. The intrarater testretest reliability assessments were made at approximately the same time of day and with 1 to 3 days in between assessments. allowing 2 attempts. 31 The BBS was administered twice by the same assessor for each participant to assess intrarater testretest reliability.
The first test (Berg A) and the retest (Berg B) were Parallel forms reliability (also called Equivalence): This answers the question, Are the two forms of the test or measure equivalent?
If different forms of the same test or measure are administered to the same group; one would expect that the reliability coefficient will be high. Reliability and Validity Essay 877 Words 4 Pages. Reliability and Validity are important aspects of research in the human services field. Without reliability and validity researchers results would be useless. This paper will define the types of reliability and validity and give examples of each.
Aug 12, 2009 To obtain the validity and reliability of the essay test I am constructing, I have to see it first from the defintion of validation and reliabilty first. Validation is the process of accumulating evidence that supports the appropriateness of the inferences made from student responses for the test. The reliability of the Berg Balance Scale has been investigated among a wide variety of subjects, although both studies investigating the reliability of the Berg Balance Scale in patients with Parkinson's disease used subjects with high Berg Balance Scale scores which incurred a ceiling effect.
