METHODS: We assessed campaign impact using serial population surveys, with the target population being women living in Victoria who were not meeting the current physical activity guidelines. Two surveys were carried out before the campaign (October 2017 and March 2018), and the post-campaign survey immediately following the first wave of TGC-Victoria mass media (May 2018). Analyses were primarily on the cohort sample of 818 low-active women followed across all three surveys. We measured campaign effects using campaign awareness and recall, and self-report measures of physical activity behaviour and perceptions of being judged. Changes in perceptions of being judged and in reported physical activity were assessed in relation to campaign awareness over time.

METHODS: Sport programme deliverers, targeting physically inactive women in Victoria, participated in concept mapping to brainstorm, sort and rate (impact on their ability to prevent/manage injury, frequency of and difficulty to overcome the challenge on a 1 (low)-5 (high) scale) the challenges faced. Analysis included multidimensional scaling, hierarchical cluster analysis and descriptive statistics (eg, mean ratings).

RESULTS: Twenty-five deliverers brainstormed 82 injury prevention/management-related challenges. An eight cluster map was considered the most appropriate representation of the participants' sorting data (mean cluster impact, frequency and difficulty to overcome rating (1-5)): time constraints (3.42, 3.69, 3.12); perceived competence in injury prevention/management (3.36, 3.50, 3.27); navigating participant perceptions and knowledge (3.35, 3.74, 3.49); information and responsibility (3.32, 3.50, 3.26); session planning and structure (3.25, 3.45, 3.07); participant engagement (3.13, 3.47, 3.08); responding to individual needs (3.07, 3.42, 2.92) and access to injury management resources (2.87, 3.25, 3.17).
