PSYD33H3 Lecture Notes - American Psychological Association, Randomized Controlled Trial, Interpersonal Psychotherapy
Document Summary
Est (part 1: essentials to know from pg. Cbt and interpersonal psychotherapy are both est (empirically supported treatments). Assumption is that est has been subjected to scientific data and trials this is done by the means of rct (randomized controlled trial). First psychotherapy study no difference between waiting list and psychoanalysis. American psychology association wanted to start designing psychotherapy studies so we can study or design studies that have experimental validity. Difference between efficacy and effectiveness is that efficacy is the outcome of an experimental design that has high control (experimental and control groups are the same) or are rcts and effectiveness are not rcts. Major argument is that ests concentrate on rcts more than external validity. Effectiveness maximizes external validity and efficacy maximizes internal validity. This design mimics the design used in medicinal studies for psychological disorderscontrol vs experimental. Psychotherapy is more complex and there is more variability (hard to control interaction, length of time).
