research Flashcards
outcome research
focused on the effects of psychotherapy
simple control group
a waiting list condition
- have to receive the intervention after a delay
typical research course
- uncontrolled study checking status before/after treatment
- comparisons with waiting list controls
- comparisons with placebo or basic counseling
- comparisons with other medications or other efficacious psychotherapies
empirically supported treatments (EST)
treatments that have met the standards set by one or more groups who have reviewed the psychotherapy literature to identify treatments for particular disorders
how can psychotherapy be harmful?
- an ineffective treatment is harmful
- if it continues to divert resources from programs that could be helpful
- some disorders worsen without treatment
- you’re withholding effective treatments that exist
how good are inpatient therapists at predicting treatment success?
no better than chance
why is clinical experience unhelpful in predicting treatment outcomes?
it taxes cognitive capacity and leaves you open to cognitive biases
clinicians rarely receive feedback
spontaneous remissions
illusory correlations
availability heuristic
sensitivity
likelihood of testing positive if one has a specified mental disorder
specificity
likelihood of testing negative if one does not have the specified disorder
treatment utility
the extent that an assessment instrument contributes to decisions about treatment that lead to better outcomes
structured interviews are more valid than semi structured because…
- good adherence to diagnostic criteria and good interrater reliability
- designed to comprehensively inquire about DSM criteria
limitations of structured interviews
- easy for patients to over/under-report symptoms
- memory is fallible
- need to use clinical judgment when getting info. from multiple sources (which is fallible)
- doesn’t reduce the occurrence of racial bias
dilution effect
validity decreases when we place more weight on the highly salient but low-validity info. at the expense of less salient, but more valid info.
hindsight bias
overestimating the likelihood that they would’ve predicted an outcome after they’re aware of the outcome
converging operations
key paradigm through which scientists interpret data from multiple investigations of a given phenomenon
- hinge on multiple measurements of the same construct
