This study is an attempt to explore the impacts of language revival on the mental health of Indigenous Australians through literature review and case study. On the basis of a delineation of how language, a sense of identity and mental health are interrelated, the study, with a focus on Barngarla reclamation, integrates the data from various reports of Australian institutions and the findings about minority groups in the U. S. and Canada, and demonstrates that language revival may enhance the mental health of minority groups like the Barngarla people through improving their self-confi dence, helping them develop resilience, and improving their sense of identity, sense of purpose and wellbeing. However, for a systematic assessment of the benefits of language reclamation to mental health, revivalists need to cooperate with mental health research professionals so as to identify, review, and (when required) adapt existing quantitative methods and tools. In addition, we contend that, in the evaluation of language reclamation activities, the revival process is as important as the revival goals.
