Efficacy and Effectiveness Research on Interventions in Sweden Between 1990 and 2019

Purpose: This article investigates the extent of effectiveness studies of behavioral, psychological, and social interventions aiming for measurable changes at the individual level in Sweden 1990–2019. Methods: The data stems from a retrospective analysis of published literature on effect studies between 1990 and 2019. Results: The results show an increase in published articles reporting on effect studies in Sweden the past 30 years, accelerating the past 10 years. However, only 25% of the studies focuses on core social work practices and only certain target groups and areas, especially children and elderly, are covered. Of these studies, only 4% are conducted by social work scholars. Conclusions: Effect studies still holds a weak position in Swedish social work research, despite of processes of professionalization and academization with national efforts to promote knowledge production for practice. This is discussed in relation to competence, opportunity, and motivation in Swedish social work and beyond.
