Single-subject research is usually conducted with one participant at a time, and we measure that participant’s behavior under different conditions. This way, we can evaluate if – and how much – an intervention changes that individual’s behavior. Here are some examples of questions we can try to answer using single-subject research.
Purpose of Single-Subject Research:
Does an INTERVENTION cause a change in BEHAVIOR?
I believe intervention does cause a change in behaviour. However, I do think the relationship between the interventionist and subject affects the degree to which an intervention may or may not be successful. For example, I am more likely to accept an intervention from my siblings than my parents. In addition, a subject’s motivation for change and desired outcomes may affect the effectiveness of the intervention.
That is an interesting statement above, especially when dealing with family dynamics. Sometimes the intervention from parents is unwarranted from a child; thinking of the teen years, when so many other dynamics to the relationship are challenged. I reflect back on my two children, somethings worked for one child and not for the other. I agree that the relationship is integral between individuals along with motivation.
