Linear probability path analysis of data from large compounds (> 20 members) of the MapSan trial. Path model for large compounds (> 20 members) subgroup assessing effects of a sanitation intervention on intermediary outcomes. Unstandardised path coefficients (bold type) represent the increase in absolute probability of the outcome as a result of a unit change in the exposure. Sections of the model corresponding to process evaluation domains and subdomains indicated by dashed lines. The model structure was more complex than that of the small compounds subgroup. Large direct effects on latrine maintenance (condition of slab/floor), privacy (working lock) and cleanliness were observed. Indirect effects on latrine cleanliness via cleaning behaviours (supported by a compound cleaning rota system) and indirect effects on latrine privacy were both minimal. A small negative effect on handwashing (soap residue) was observed. Abbreviations: ‘chefe’, chefe de composto (informal compound leader); HWF, handwashing facility; HWWS, handwashing with soap
