Notes: Indicated sub-constructs reflect those conceptualised via our hypothesised collective efficacy framework. Items presented in italicised font were hypothesised to have an inverse relationship with CE. Given the various conceptualisations of these latent constructs, substantive justification existed for the re-conceptualisation articulated in our EFA-derived factor structures. * self-referent item prompts about the respondent’s own sense of self, agency, autonomy, and level of engagement within his/her community; all other items reflect group-referent items prompts about ecological aspects of the respondent’s community; items that refer to endogenous community structures (e.g., community-initiated/organised community associations)—local endogenous structures used as examples, but should be adapted to the given local context; items that refer to exogenous community structures (e.g., government or NGO-initiated/organised community associations)—local exogenous structures used as examples, but should be adapted to the given context; § measured through different scenarios reflecting different levels of urgency/need.
