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?

Will single-subject research determine if my roommate will make dinner more often based on the purpose of washing the dishes?
Conducting a single-subject research to determine if providing the student with books that match her reading level will serve the purpose of increasing her engagement in free reading.
Conducting single-subject research by spraying your cat with water when she scratches the couch serves the purpose of reducing her scratching 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.

Hi Hurrain
I totally agree that you are right, intervention does cause a change in behaviour, also, effect the relationships. Thanks for sharing. Have a great day!

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.

Intervention definitely changes behavior. I understood why behavior analysts choose to do a single-subject design to collect data.

Avatar Amelie Eidem November 6, 2024 at 4:02 pm

Intervention is a great way to change behaviour.

Avatar Diana Francis November 9, 2024 at 4:15 pm

Intervention is a critical way to change a behavior coupled with positive reinforcement.
