Abstract
BACKGROUND: Good interpersonal communication is the cornerstone of social work practice, enhancing the outcomes of people in receipt of its services. Social workers' communication skills are often identified as an area of concern. Communication skills can be developed and refined through training or education. The teaching and learning of communication skills is firmly embedded in many social work qualifying courses; however, considerable heterogeneity exists regarding such complex interventions and the theoretical underpinnings of which have not been made explicit. Realist synthesis can help explain how, why, for whom and in what circumstances an intervention might work, which is an important first step for helping educators to tailor courses to meet the needs of different learner groups and, where applicable, the employing agencies and government departments who fund them. METHODS: Realist synthesis is an interpretive, theory-driven and explanatory approach that aims to explain the interplay between the context, mechanisms and outcomes of interventions. This realist synthesis seeks to understand and explain to what extent, how, why, for whom and in what circumstances complex educational interventions aimed at teaching communication skills to social work students produces its effects. A five-step process will be followed iteratively. In step 1, the initial programme theory will be developed. Step 2 will involve searching for evidence. In step 3, selection and appraisal will take place. Step 4 requires data to be extracted and organised, and in step 5, data will be analysed and synthesised. DISCUSSION: The teaching and learning of communication skills in social work education is under theorised. The findings from this realist synthesis aim to help policymakers and educators make informed decisions about the design and delivery of complex educational interventions aimed at improving the communication skills of social work students. The realist synthesis will be conducted and reported in accordance with the RAMESES guidelines and standards.
