Social workers strive to make informed decisions about the interventions they implement. These decisions should be driven by what the research data say. As a result, social workers have been called to systematically evaluate the effectiveness of the interventions they implement. A common way to evaluate interventions is to use a single-subject design. This involves monitoring an outcome for an intervention implemented for one client. After a social worker works with the client to determine the outcome to be measured, the following steps to the evaluation might look like this:
- When evaluating social work practice, social workers can use a single-subject design that looks like this:
O1 X O2
The Os are the observations of the outcome that will be measured. For instance, O1 is the first observation or measurement of the outcome before the intervention is implemented (pretest). O2 is the second observation of the outcome after the intervention was implemented (posttest).
With single-subject designs, the social worker might evaluate a single client or a small number of clients and the intervention that was implemented for them.

- Implement the intervention
- Administer the same instrument, after a specified time period
- Monitor to determine if there have been any changes in the outcome
In this Discussion, you use the lens of resiliency When knowledge comes from theory, it is based on statements that have been tested using science.
” data-hasqtip=”17″>theorywhen reflecting on a case from your fieldwork, and then you consider how to measure the effectiveness of a possible intervention.
To prepare, read this article listed in the Learning Resources:
- Smith-Osborne, A., & Whitehill Bolton K. (2013). Assessing resilience: A review of measures across the life course. Journal of Evidence-Based Social Work, 10(2), 111â€“126. doi:10.1080/15433714.2011.597305
- Reflect on your fieldwork experience, and identify a case where it would have been beneficial to employ resiliency When knowledge comes from theory, it is based on statements that have been tested using science.
” data-hasqtip=”18″>theory. Describe the case in 2 sentences.
- Describe the presenting problem in one concise sentence.
- Describe an intervention you would implement to promote resiliency.
- Identify an instrument from the Smith-Osborne and Whitehill Boltonâ€™s article that would be appropriate when employing a single-subject design to evaluate how effective the intervention is in increasing the clientâ€™s level of resiliency.
- Explain why you selected the instrument.
- In other words, why would the instrument be appropriate? (Consider the age of the client and for whom the instrument was designed, how feasible it would be to administer the instrument such as cost, time to administer it, etc.).
