PURPOSE: Effective and efficient health services require efforts to increase collaboration among health professionals. One of the barriers to effective collaboration is stereotypes. Stereotypes represent perceptions or perspectives about a person or group of people. This study aims to explore the perceptions of health professional students and practitioners regarding stereotypes. METHODS: This was a qualitative study using a phenomenology approach. A sample of health professions students from both preclinical and clinical stages, as well as health practitioners, was selected using a maximum variation sampling method. Primary data collection was conducted through focus group discussions. Data obtained were analyzed using thematic analysis. A total of nine focus group discussions were conducted. RESULTS: Four themes were identified from this study, including the types of stereotypes, factors affecting stereotype formation, the implications of stereotypes, and how to overcome stereotypes. Stereotype formation was affected by the lack of understanding of other health professions' roles, hierarchical culture, personal experience in receiving healthcare, and community view. Stereotypes among health professionals created obstacles to healthcare team communication and reduced self-confidence in certain health professionals. These stereotypes may be overcome through competency development and knowledge sharing among professionals as well as through education on other health care professionals' roles and competencies so that each profession possessed similar goals for patient safety. CONCLUSION: Both positive and negative stereotypes negatively affected collaboration. Stereotypes were greatly affected by multifactorial causes. Therefore, understanding other professions' roles and conducting interprofessional education are important to overcome stereotypes.
