Late teens and early adulthood is the peak age of onset for mental disorders. Currently, there is a gap between primary mental health care and more intensive mental health services for young people in New South Wales (NSW), Australia. Two headspace Early Intervention Teams (hEITs) were developed to bridge this gap in Sydney Local Health District (SLHD), in Sydney, Australia. This study aims to explore clinician experiences of hEIT after the first 2 years of implementation. Semistructured interviews were conducted with key clinicians working within hEIT or closely associated with hEIT. Nine interviews were conducted, transcribed and analysed using qualitative thematic analysis. Four themes were identified: (1) building a bridge between services, (2) filling a clinical gap, (3) service collaborations and their challenges and (4) difficulties of small team size. There is evidence that clinicians value the service provided by hEIT. There are difficulties such as referral confusion, staff turnover and suggestions to increase staffing to improve the stability, skill diversity and viability of the service. Findings have implications for other collaborative youth mental health models.
