Abstract:
Assessment of the retest-reliability and sensitivity to change of the ICD-10-Symptom-Rating (ISR) is provided. The ISR was filled out repeatedly by a non-clinical as well as different samples of psychosomatic patients. Between the two measurements either no or an integrated psychosomatic treatment took place. During the treatment free phase a high degree of stability of the test scores was expected, whereas a significant improvement of test scores was expected for the respective scales over the treatment phase. The retest-reliability for the individual scales ranges from 0.70 to 0.94. Between admission to a psychosomatic treatment and discharge significant differences were found for all scales. The retest-reliability showed satisfactory results comparable to similar, symptom-oriented instruments. Furthermore, the instruments reproduces symptomatic changes consistently and is - from our point of view - suitable for the assessment of change.

Measures of Intelligence
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this; it...

Interpretation of Confidence Intervals
Confidence intervals have confidence coefficients that are crucial for their interpretation. The most common confidence coefficients are 0.90, 0.95, and 0.99, which can be written as percentages–90%, 95%, and 99%, respectively.
Suppose a person calculates a confidence interval with a confidence coefficient of 0.95. In that case, they can...
