ABSTRACT Objective Evaluate survey respondents’ perceptions concerning the acceptability and effectiveness of a localised, community-based mental health program. Method Avondale University and Lake Macquarie City Council partnered to implement an online, lifestyle-based program for all Council residents during a COVID-19 lockdown period. The University and Council promoted the program through established networks, resulting in 2390 registrations representing 4041 participants. Researchers invited registered users to respond to a post-program survey assessing their perceptions concerning program satisfaction, mental health benefits, and self-efficacy for managing mental health. Qualitative questions probed respondents’ likes and dislikes and were analysed thematically. Results Response rates were low, 6% (138/2390) of registered participants completed the post-program survey. Of the 138 responses, 99% indicated they would recommend the program to others, and 94% believed they gained skills to manage their mental well-being into the future. Themes generated from the qualitative data indicated that respondents liked the video content and delivery style, community camaraderie, personal empowerment, and easy accessibility. Some respondents found online accessibility problematic, disliked the delivery style, and experienced technical difficulties. Discussion The findings from a limited number of respondents indicate that a localised, community-based lifestyle program may offer a replicable model that is acceptable and effective in improving perceived mental health and self-efficacy in managing mental well-being. Survey respondents valued the practical content, community togetherness and emphasis on self-empowerment.
