Key issues from primary mixed methods research and scoping review and associated intervention features.

Issue identified by research	Intervention features addressing the issue
Ambulators with SCIa participate in low levels of leisure-time physical activity, and no interventions exist for this group [7].	Intervention should be developed to improve physical activity participation.
Exercise intervention studies lacking measurement of psychosocial outcomes [7].	Intervention must address and measure psychosocial constructs related to physical activity participation.
Correlates related to physical activity include physical and psychological capability (eg, pain and lack of knowledge), environmental and social opportunity (eg, time and underestimated disability), and reflective and automatic motivation (eg, intentions and boredom) [7] Barriers to physical activity include lack of knowledge, weak beliefs about capabilities, lack of coping planning, and high goal conflict [28]. Coping planning, action planning, goal conflict, and skills significantly predict physical activity [28].	Intervention must target the following constructs through educational modules, behavioral support, and peer support: Physical activity guidelines and benefits (knowledge) Self-monitoring and goal setting (goal conflict) Action planning Coping planning Confidence (beliefs about capabilities) Skills
A total of 35 types of physical activity recorded and organized into 10 higher-order categories (eg, walking, resistance training, and rock climbing) [28].	Intervention content must include educational modules that refer to these types of physical activity when examples are used. A list of these types of physical activity as ideas for participants should also be included.
Ambulators with SCI have physical activity experiences, which are shaped by feelings of ableism, feeling sidelined, and the effects of their SCI [29].	Behavioral support in the intervention must be provided by a person who understands this context for physical activity participation.
Conditions and elements of quality physical activity experiences map onto the Quality Participation Framework [41] and Quality Parasport Participation Framework [29,40].	Conditions and elements of quality physical activity experiences must be included as a separate module for intervention. Quality of physical activity experiences must be referred to throughout the intervention.
Ambulators with SCI lack sense of community, especially in physical activity settings [29].	Peer support must be included and prioritized in intervention delivery.
