Systematic review of international ethics knowledge in the speech-language pathology literature (1980–2022)

A systematic review was conducted to describe various viewpoints expressed in speech-language pathology literature over four decades concerning ethics knowledge in the profession. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were employed. Our sample search encompassed peer-reviewed journal articles sourced from electronic databases including MEDLINE, CINAHL, ERIC, MasterFILE Premier, E-Journals, Africa-Wide Information, and Academic Search Premier, spanning the period from 1980 to 2022. The initial search of articles identified 139 papers. After applying rigorous inclusion and exclusion criteria, 60 full-text papers were deemed suitable for inclusion. We conducted a qualitative, deductive analysis of the relevant data and findings. Studies primarily concentrated on the speech-language pathologist’s roles in rehabilitation/management and education, research, and administration. A predominant focus of these papers revolved around moral judgement, a fundamental component of moral behaviour. Findings suggest an evolving landscape within the speech-language pathology discipline, with an increased focus on moral judgement, professional competency, and rehabilitation/management. The findings highlight a consistent need for further development and emphasis on ethics in education, research, administration, and advocacy/consultation roles. This underscores the necessity for ongoing ethical education and support to ensure practitioners are well-equipped to navigate the complex ethical landscape of their professional practice.
