Specificity of an instrument used for diagnosis refers to what?

Homework Answers

Answer #1

Specificity of an instrument used for diagnosis refers to ability to detect the absence of a condition or illness.

Specificity of a screening or diagnostic test is the proportion of patients without the disease who have a negative test result or true negative. A test with high specificity is very good at identifying the patient without any disease. Specificity is required to be high in order that few cases without the disorder are screen positive (avoiding falsely alarming parents and costly referral for in-depth).

Based on the following information, calculate the specificity. A screening test was used with 224 children ages 3-5 years attending a subsidized day care to determine if any of the children had speech/language delays using the ASQ (Ages and Stages Questionnaire). The same children were also given a clinical evaluation by a Speech and Language Pathologist (SLP) which is the gold standard for diagnosis of speech/language delays. The ASQ found that 75% of the children had a speech/language delay. Of...

An instrument has been used to measure the length of a part. The result was 6.70052 cm. An error-of-measurement study on the instrument had the following results: Bias: +0.00254 cm (on the average, the instrument reads 0.00254 cm high). Repeatability (precision): 0.001016 cm (1σ). Make a statement concerning the true value of the part just measured. State all assumptions needed.
