Social workers can use quasi-experimental strategies as alternatives to repeated baseline measurements in single-case experimental designs (SCEDs). This supports evidence-based practice (EBP) when traditional SCED methods are not feasible for individual client interventions.
Area of Science:
- Social Work Research
- Evidence-Based Practice
- Quasi-Experimental Designs
Background:
- Social workers face challenges implementing evidence-based practice (EBP) due to the unique needs of individual clients.
- Single-Case Experimental Designs (SCEDs) offer a method for evaluating intervention effectiveness at the individual level.
- Traditional SCEDs often require repeated baseline measurements, which can be difficult to implement in routine social work practice.
Conclusions:
- Implementing quasi-experimental elements in single-case designs can help social workers evaluate interventions more rigorously.
- These methods move beyond simple narrative evaluations, providing stronger evidence for intervention effectiveness.
- The study provides practical alternatives to enhance the application of EBP in social work settings.
