Assignment 1
Reliability and Validity
Locate an established survey/test/assessment/instrument, which is commonly used in the field of psychology, then provide the following information:
Wait, how do I find an instrument?
Download the List of Psychological Tests found in Modules 5-6 and scroll through the plethora of instruments. Find one that you think interests you and start from there. Be creative and start with the internet to start your research on the instrument of choice.
Title of Instrument
Include full title and name of developers.
Description
Provide a full description of the instrument. This includes the intended use of the scale and the target population. Also include the number of items within it and note if there are any subscales within the entire scale. Include any other relevant information, not including psychometric properties. This should be about 1-page in length.
Psychometric Properties (not specifically related to the instrument of choice)
Summarize two major types of Reliability. Specifically, define each term and discuss the application and relevance to the instrument, which you have chosen (1-page in length).
Summarize two major types of Validity. Specifically, define each term and discuss the application and relevance to the instrument, which you have chosen (1-page in length).
Psychometric Properties of the Instrument (include instrument name here) (1/2 – 1-pages in length).
Include here any type of psychometric properties of the instrument that you can locate. This includes various forms of validity and reliability. Include the correlational coefficients (r = .41).
How do I locate the psychometric properties of an instrument?
One way to locate the psychometric properties is to go to the Tests & Measurements database in the NSU library (see screenshot on next page).
Another way is to simply Google the title of the instrument followed by the word “psychometric properties.” For example, if you’re interested in writing your assignment on the Beck’s Depression Inventory then in the search engine simply type “Beck’s depression inventory psychometric properties.”
The search will reveal many studies that have been conducted on the scale with the primary focus in establishing the validity and the reliability of the instrument.
