This paper uses secondary analysis to understand how COVID-19 shaped people’s experiences with psychosocial support services in Australia. Data are drawn from questionnaires (n = 66) and semi-structured interviews (n = 62), conducted for a national service evaluation, with 121 people living with enduring mental health conditions and using psychosocial support services. Data relating to COVID-19 were inductively coded and analysed using constant comparative analysis. Most people’s experiences included tele-support. While some people described minimal disruption to their support, many reported reduced engagement. People’s wellbeing and engagement were influenced by: their location, living situation and pre-COVID lifestyles; physical health conditions; access to, comfort with, and support worker facilitation of technology; pre-COVID relationships with support workers; and communication from the organisation. The findings can help services prepare for future pandemics, adjust their services for a ‘COVID-normal’ world, and consider how learnings from COVID-19 could be incorporated into a flexible suite of service delivery options.
