PSY343H1 Lecture Notes - Lecture 2: Panic Disorder, Dependent And Independent Variables, External Validity
Document Summary
Issues that challenge reliability: clinical expectancies could have effects on trial outcomes, randomization usually takes care of confounds on reliability. Most medication trial studies do not test against each other. Doesn"t want to be less effective than already existing drugs. Dependent variable: symptom reduction, sustainability of clinical outcome, quality of life back to baseline. Most experiments are done on uni student, uni students are not the most generalizable group of people. Cohen"s d: small -> . 3, medium -> . 5, large -> . 8. Measuring cohen"s d does not illustrate how the individual"s doing: depressed individual may be doing better after treatment but may still be depressed. Usually 20% reduction of symptoms, leaving 80% symptoms still untreated. Ocd for example complete recovery is not a realistic goal. Panic disorder -> episodic, may lend to complete recovery. Do we attribute the result of patients who seek additional therapy to cbt.
