The dependent variable can be withdrawn or varied as is necessary to the study. Single research design is the most applicable because it provides a framework for one on one work with a single client.
Single research design focuses only on a single subject as the name suggests. As an alternative to group research design, single system design is structured differently in such a way that it can easily adapt to social work practice. As a result, it is the most accurate method of research on interventions and other social work practices (Royse, 2009). The process of single-system design entails identifying target problems, undertaking pre-intervention measures, providing the intervention, taking additional measures and evaluating the efficacy of the intervention.
Multiple base designs will ensure that the client does not reverse to the old behaviors during the withdrawal phase. As the name suggests, multiple baseline designs introduces the baselines in sequence. For instance, the baseline for self-efficacy may last for four sessions while the baseline for parenting skills may last for seven sessions. These baseline sessions may overlap, allowing the researcher to determine the behaviors influenced by the intervention while controlling for the external events. On the other hand, Single-system design is the best choice since it focuses on the individual and not a group. Contrary to group design, single system is concerned with whether an intervention works for the client while the group design is concerned with the average change. It delivers a framework that allows the practitioner to asses and specifies the client’s goals, implement interventions, safely terminate with the client and perform follow up activities. SSD was created specifically to address social work practice that group designs could not. As such, it is most suited for social practitioners especially in evaluations of efficacy of their programs with
