This thesis addresses a significant gap in the literature by exploring the professional experiences of Indigenous clinicians delivering mental health interventions to Indigenous children and youth. The study focuses on the clinicians' experiences of culturally adapting mental health interventions and seeks to understand the support they receive in achieving the delivery of these interventions. Six practicing, self-identified Indigenous child and youth mental health clinicians participated in the study. The Indigenous child and youth mental health clinicians shared their experiences through in-depth conversations, which were analyzed while employing a qualitative, exploratory approach within the framework of The Dene Laws. Data analysis revealed three central themes: ‘Utilizing Culturally Adapted Mental Health Interventions,’ ‘Supportive Factors for Culturally Adapting Mental Health Interventions,’ and ‘Examining Barriers and Identifying Areas for Improvement.’ The findings provide valuable insights into the clinicians’ use of collaborative, intuitive, and client-centred approaches. The study further highlighted the necessity for systemic support to overcome challenges and improve the delivery of culturally adapted mental health care for Indigenous children and youth.
