Locate a pre-existing instrument such as a survey or scale (or a snippet of at least 5 questions and some description of the scoring mechanism) that can be used to measure one of the variables within your research proposal. You may find this questionnaire through the articles that you read, through the references provided within those articles, or possibly through one of these resources (*Note: you cannot develop your own instrument):
Mental Measurements Yearbook: https://libguides.asu.edu/mentalmeasureLinks to an external site.Links to an external site.Links to an external site.. This source includes many different psychological measures.
The Health and Psychosocial Instruments database: https://libguides.asu.edu/healthinstruLinks to an external site.Links to an external site.Links to an external site.. This source includes different interdisciplinary scales.
PsycTESTS: https://libguides.asu.edu/psyctestsLinks to an external site.Links to an external site.Links to an external site.. This source includes access to psychological tests and other instruments.
Write a 1-2 paragraph post that answers the following prompt:
In your own words, explain generally what should be considered when constructing survey questions (hint: see Chapter 7, starting on page 128) and identify at least TWO ways that a researcher can develop strong questions or a “better” measurement (there are lots of ways, which are highlighted in our text and lectures so just focus in on two of your favorites)
Next, describe how the principles of instrument development (i.e., the types of questions) relate to the reliability and validity of that scale (hint: see Chapter 5). Use the concepts you learned in this week’s assigned readings and lectures to support your ideas with an in-text and corresponding reference citation.
Then, describe the instrument you found that measures one of your variables and evaluate its suitability for your research project.Clearly explain what is measured in this instrument.
Discuss the scale of measurement (nominal, ordinal, interval, or ratio)
Explain how the questions within this instrument are scored and how that score is interpreted (for example: what does a higher score versus a lower score mean; do you add the items together? or are there separate subscales?).
Look back at the concepts you noted from Chapter 7 about question development and explain what about your scale follows these principles.
Post a reference citation of your instrument at the bottom of your discussion post.
Post an example of 2-3 questions from this instrument and the response option prompt (e.g., “strongly disagree to strongly agree”)
