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: Administer the instrument before the intervention is implemented **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 theory when 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), 111-126. doi:10.1080/15433714.2011.597305 Post: *Reflect on your fieldwork experience, and identify a case where it would have been beneficial to employ resiliency 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 Bolton’s article that would be appropriate when employing a single-subject design to evaluate how effective the intervention is in increasing the client’s level of resiliency. *Explain why you selected the instrument.
