Empirically based treatments
- **tested on the graphs in lecture slides
- interchangeable names: empirically validated/ supported treatments. Empirically based practice.
- Has to have multiple studies in order to be classified as empirically based treatments. Must have a
statistically significant change in an identified problem. Must be behaviourally, so it can be
measured and seen.
- Criteria must be made for the problem (suicide attempts, binge eating etc.- things you can see
infront of you)
- Systematic empirical research: very rigorous studies, controlled and expensive.
Efficacy vs. effectiveness
- Efficacy study is highly controlled and focuses on a specific disorder. Specific group of people doing
specific things for a specifc amount of time
- Effectiveness study is applied research. Study done in the real world. How effective is it in the real
- Every study is a balance between the two. The more applied the less controlled.
Path to EBP
- Has to go through a lot of testing
- Case studies/clinical observation: pick one person and focus on everything that’s happening.
o it takes just an interesting case and a new method. Something new
- Pre-post studies: when you measure them in pre treatment and measure them in post treatment
o You don’t know everything about the study, just know pre and post treatment results
o Additional questions: maybe it isn’t just the treatment that produces the changes
Adherence: the experimenter doing what they say they are going to do. Becomes an
issue when talking about treatment validity. To make sure experimenter is
practicing adherence: Make sure person is certified, adherence measures (Checklist
to make sure they are doing what they are supposed to do), videotape all sessions
and send it to someone who has been trained to judge.
Clinically significant change (vs statistical change): clinically significant is judged by
how we classify the patient if they come out of the clinical group and get into
normal range. Clinically significant is always statistically significant, but statistically
significant is not always clinically
