Document Summary
Assessment is collecting relevant information in an effort to reach a conclusion. The specific tools used in an assessment depend on the clinician"s theoretical orientation. Hundreds of clinical assessment tools have been developed and fall into three categories: o clinical interviews o tests o observations. To be useful, assessment tools must be standardized and have clear reliability and validity. To standardize a technique is to set up common steps to be followed whenever it is administered o one must standardize administration, scoring, and interpretation. Reliability refers to the consistency of an assessment measure. A good tool will always yield the same results in the same situation. Two main types: o test retest reliability yields the same results every time it is given to the same people o interrater reliability different judges independently agree on how to score and interpret a particular tool. Validity refers to the accuracy of a tool"s results.
