Peer work is a rapidly growing part of the mental health workforce, yet few studies explore the implementation of peer work in youth mental health. Qualitative focus groups were conducted with eight youth peer workers at the commencement of their employment, then at 3-months and 6-months after this time. Data were transcribed verbatim and analysed using thematic and trajectory analysis. The three main findings included: (1) there was a trajectory from fear to hope; (2) there was an improved understanding of benefits and role definition over time; and (3) there was an evolving concept of understanding shared experiences as a primary asset. Known barriers to implementing peer work are likely to occur in youth mental health settings as well. Ensuring that adequate training, change management and tailored support strategies are important to maximise the chances of successful youth peer work programs.
