PSY 105 Lecture Notes - Lecture 6: Inter-Rater Reliability, External Validity, Internal Validity
Document Summary
Clinical assessment: much larger than diagnosis, systematic evaluation and measurement. Social: degree of fit between symptoms and diagnostic criteria, part of assessment, mostly symptom based. Signs--something you observe whether the patient reports it or now. Purpose: why are we assessing: understanding the individual, predicting behavior, treatment planning and utility, evaluating outcomes. Evaluate how we"re doing; how is the treatment process going; is the patient better or worse: assessment is only as useful as it informs treatment (informs impacts on the patient) Funnel analogy: start broad and get more narrowed as you go along! Reliability--(synonym: consistent) understanding whether what you"re assessing and how you"re assessing has consistency in measuring: measurement consistency. Test, and then retest later to quantify the degree to which there is consistency. More than one rater rating the same subject; where there is high agreement or consistency, you have interrater reliability.
