used as an example. For specific example answers for the test I completed the results all rated “low” for all personality disorders. Limitations arise from decreased reliability and validity and issues with credibility of responses due to response bias. Content validity‚ construct validity and criterion-related validity as well as test-retest reliability will be presented. The forms of response biases that will be discussed are social desirability‚ acquiescence‚ halo effect‚ extreme responding‚ midpoint
