Reliability

Influences on reliability include: the test itself; how the test is administered and scored; and the test taker. All of these items can cause errors. The TSI reports a reliability rating on each scale and overall reliability of .93 for a combined sample of 3,401 teachers across the US. Kourmousi, Darviri, Varvogli, & Alexopoulos (2015) adapted the TSI to a Greek version…

refers to a tool implemented in analytical psychology. Just like any other scientific tool, criminal profiling has its disadvantages. The disadvantages influence the validity, reliability, and utility of the technique, making it to be classified as a tool rather than science. For one to be conversant with the validity, reliability, and usefulness of this tool, understanding its definition is crucial. Criminal profiling refers to the procedure of categorizing personality mannerisms, behavior…

Addiction Potential Scale vs Addiction Severity Index The Addiction Potential Scale (APS) and the Addiction Severity Index (ASI) are both used to measure substance abuse. Each one has its advantages and disadvantages, but they both work together to determine not only who has the potential to become addicted to alcohol and drugs, but also the severity of the addiction. Both are critical to assessing a person’s addiction, or likeliness to develop an addiction, so that the individual can be treated…

CHAPTER THREE: Chapter Three was the beginning of how to create a test and what is needed for a test to be considered “good”. Two important factors that help determine if a test will be good is understanding norms and reliability. Figuring out a norm group for a test is really crucial because it is a sample of examinees who are the representative population of people the test is intended to measure. This information is important because you do not want to give a test that is meant for an age…

It has fifteen items and two subscales: pain severity and pain interference. Each item is rated on an eleven-point scale, from 0-10, where 0 indicates no problems and 10 indicates maximal problems [212]. The reliability and validity of BPI are supported by the literature. Test-retest reliability of pain severity and interference are 0.98 and 0.79, respectively. Construct validity was tested through the correlations with the same construct; the correlation between the pain severity subscale and…

However, negatively scored items were used sparingly (see Appendix B). Validity and Reliability An instrument is valid when it measures the construct it was designed for, and reliable when an instrument can consistently produce the same results over time, across different situations (Field, 2003). Content validity is an evaluation of the…

A panel of experts is needed to review the instrument, and determined the validity and reliability. The group discussion was an example of panel of experts, who determined the content of validity and reliability between the items composing in the instrument. The reliability was conducted before the expert panel review, which for this assignment were my classmates. The panel of experts provided suggestions with regard to improving…

Concept of a Leader There are many definitions of leadership. The Collins English dictionary defines leadership as “the leader of a party or group.” Yet true leadership is much more than that. A decent leader has an excellent character. It is of most extreme significance that a pioneer is reliable to lead others. A pioneer should be trusted and be known to carry on with their existence with genuineness and respectability. A decent leader has a superb character. It is of most outrageous…

assessed by experts and made sure the scales were correct. In the development of the Japanese version there was special attention put on the differences between North American and Japanese cultural difference. Results showed high internal consistency reliability with a Cronbach’s alpha of .87 and the mean inter-item correlation of .24 (Kojima et al., 2002). Factorial validity was proven by conduction a factor analysis and the researchers found “an almost identical pattern matrix with the…

tests would score higher on lower level of the same test. To answer this question much of the research on out-of-level testing has examined the effects on raw scored and derived scores. Many have turned to chance score as a criterion measure of reliability. When the effects of the out-of-level testing on chance scores have been examined, researchers found that the number of students who score at the chance level on a…
