Transcript of Scientist-Practitioner Model
Single Subject Design
Evaluation methods where
of a subject's (client's) behaviour are taken over time, including measurements before, during and after an intervention is implemented.
- period in which no intervention is being offered to the client
- the period in which the intervention is being implemented
3) Follow-up Phase - "checking-in" period to see if intervention effects maintained
The dependent variable is the measurement of the behaviour targeted for change (e.g., rates of self-injurious behaviour)
With intervention, the dependent variable may increase, decrease or stay the same compared to baseline. These changes are evaluated to determine if intervention was effective or not.
The independent variable is the introduction of the treatment being implemented (e.g., medication, reinforcement system).
Ideally, the intervention is the only thing changed. All other variables should be controlled for, kept constant (e.g., don't implement medication + reinforcement system together or don't implement an intervention when the client is moving).
Data on the dependent variable is compiled and graphed. This allows for interventionists and researchers to visually analyze the results in order to evaluate effectiveness and client progress.
Assessment data can also be graphed in order to visually present comparisons and support the identification of functional relationships (and thus the treatment being implemented).
of the research to keep up to date on assessment and intervention techniques
of our own interventions using single-subject designs
: sharing data/results from our clinical settings with other professionals and the scientific community.
